Effect of immediate all-digital restoration of single posterior implants: The SafetyCrown concept on patient-reported outcome measures, accuracy, and treatment time-A randomized clinical trial.

The SafetyCrown workflow facilitates the immediate restoration of posterior single sites with the one-abutment/one-time concept. This randomized clinical trial aimed to assess the direct effect of immediate restoration on dental patient-reported outcomes (dPROs), feasibility, implant accuracy, and time. Participants with a single posterior edentulous site for late implant placement underwent optical impressions, shade selection, and cone beam computed tomography. After virtual treatment planning, they were randomized into the test group and the control group. For the test group, individual definitive hybrid abutments were prefabricated. The next step was a fully guided surgery with printed guides. After the implant was placed using guided surgery, the abutment was inserted. A chairside CAD/CAM workflow was used to provide the patient with a provisional restoration. Implants in the control group were left submerged to heal. Oral health-related quality of life (OHRQoL) was assessed using the OHIP-G14, and dPRO was measured using a 10-item visual analog scale (VAS) questionnaire. Additional measurements of implant accuracy and time were performed. Follow-up was performed 7 to 10 days after implant placement. Thirty-nine participants with 45 restorations were included (test group: 23, control: 22). Immediate restoration was successful in 21 out of 23 implants (91.3%) in the test group. Both groups exhibited decreased OHRQoL without significant intergroup differences, while patient satisfaction was high overall. Test group participants perceived higher benefits and satisfaction with immediate loading than participants in the control group. Implant accuracy averaged 0.60 mm at the shoulder and 0.95 mm at the apex. Operative time was longer in the immediate loading group (61.9 min) than in the control group (32.1 min) (p < 0.001). Considering the limitations, the immediate restoration of late placed posterior implants using the described workflow proved feasible in 21 out of 23 cases. Both groups achieved high patient satisfaction with no differences in OHRQoL during the first week. Patients who received immediate loading rated the benefits very highly and were satisfied with the provisional restoration during the healing period.

The impact of craniofacial and dental osteogenesis imperfecta manifestations on oral health-related quality of life of children and adolescents.

Craniofacial and oral manifestations of Osteogenesis Imperfecta (OI) can affect the functioning of the stomatognathic system and impact the patient's quality of life. The objective of the study was to evaluate the relationship between craniofacial and oral manifestations and the Oral Health-related Quality of Life (OHRQoL) of OI children and adolescents. A total of 30 OI patients aged eight to fourteen years old followed up at the Oral Care Center for Inherited Diseases were enrolled in the research. OHRQoL was assessed using the short form of the Child Perceptions Questionnaire (CPQ) for eight to ten-year-olds (CPQ8-10) and 11 to 14-year-olds (CPQ11-14). The relationship between the OHRQoL index and its assessment domains, OI types, and the presence of dentinogenesis imperfecta (DI), class III malocclusion, and dental agenesis were evaluated. The median CPQ score of patients was 5, and there was no significant difference in OHRQoL between children and adolescents, nor associated with the disease severity or the presence of DI. The oral manifestations evaluated did not directly impact the patients' OHRQoL. The study demonstrated that the perception of OHRQoL is similar for both adolescents and children. The oral symptom was the most relevant domain for the index among patients aged eight to fourteen years while the emotional well-being was the most impacted. this study makes contributions by indicating that addressing dental care for children and adolescents with OI is important in clinical management and better OHRQoL for this population.

Oral Health-Related Quality of Life in Different Subtypes of Ehlers-Danlos Syndrome.

This study assessed differences in the oral health-related quality of life (OHRQoL) between subtypes of Ehlers-Danlos syndrome (EDS). For statistical analysis, participants were divided according to their subtype: classical EDS (cEDS), hypermobile EDS (hEDS), and vascular EDS (vEDS). All other subtypes were descriptively analyzed. Free-text questions and the German short form of the Oral Health Impact Profile (OHIP-14) were used. Finally, 295 questionnaires were included, representing 10 different EDS subtypes. The mean OHIP score of all participants was 19.6 points (standard derivation (SD) ± 12.3). The most predominant subtypes showed similar reduced OHRQoL, with 18.0 (cEDS, ±12.9), 19.5 (hEDS, ±12.0), and 15.2 (vEDS, ±11.6) OHIP points. For all other subtypes, the OHIP values varied. Participants waited an average of 21.8 years (±12.8) for their diagnosis. However, within the predominant subtypes, vEDS patients waited a noticeably shorter period of 13.3 years (±13.0; p = 0.004) compared to participants with hEDS. Additionally, this study showed no difference in OHRQoL for the predominant subtypes regardless of whether a participant was a self-help group member (18.8, ±12.0) or not (19.4, ±12.1; p = 0.327).

Translation and validation of Sinhala version of modified EORTC QLQ-OH15 in oral cancer patients who receive radiotherapy with or without chemotherapy in Sri Lanka

BackgroundThe recognition of patient-reported outcomes for oral cancer is important in improving patients’ quality of life. The aim of this study was to translate and validate the modified Sinhala version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Oral Health Module (EORTC QLQ-OH15).MethodsA cross-sectional study was conducted to validate the EORTC QLQ-OH15 that was modified after adding two questions to the original questionnaire. The two questions added were ‘difficulty in opening the mouth wide’ and ‘trouble with talking’ which affect oral health related quality of life (OHRQOL) of oral cancer patients receiving radiotherapy. The Sinhala translated modified EORTC QLQ-OH15 and already validated the core questionnaire EORTC QLQ-C30 were self-completed by 85 adult oral cancer patients who received initial anti-cancer treatment with radiotherapy with or without chemotherapy. Content and face validity were examined by an expert panel. Construct validity was confirmed by using factor analysis, multi-trait scaling analysis, and known group comparison. Reliability was assessed by internal consistency, test–retest reliability by Wilcoxon Signed Ranks Test and intra class correlation coefficient. Responsiveness to change was assessed.ResultsThe majority of participants (58%) were aged 50–69 years and 84% were males. Nearly 32% had cancer of the anterior two thirds of the tongue. Of the sample, 66% received chemo radiotherapy. Thirteen items were included for the factor analysis. They were loaded for four factors. Three scales ‘Eating problem’, ‘Gum and Speech problem’ and ‘Soreness’ loaded with 5, 4 and 3 items respectively and single item ‘teeth’ to a one factor with the total variance explained was 72.74%. Mann–Whitney U tests for all three scales were statistically significant confirming the ability of the modified EORTC QLQ-OH15 to detect expected differences in OHRQOL in clinically different groups. Cronbach’s alpha for all the scales were more than 0.8. Wilcoxon Matched Paired Sign Rank Test showed highly significant results (p < 0.05) for all three scales revealing high responsiveness.ConclusionsThe modified Sinhala version of the EORTC QLQ-OH15 is a valid, reliable tool that can be used to measure OHRQOL in oral cancer patients who receive radiotherapy with or without chemotherapy.

Assessment of Quality of Life and Supporting Structures in Implant Retained Mandibular Overdenture: A 5-Year Cohort Study.

AimTo assess oral health-related quality of life (OHRQoL), marginal bone loss (MBL), and changes in soft tissue including probing pocket depth and implant stability in 2 implants retained mandibular overdentures during 5 years follow-up periods.MethodsForty completely edentulous patients with age 51–64 years were recruited for that longitudinal cohort study. Complete dentures were performed for all participants. Two implants (3.6 × 11.5 mm) were installed in the canine areas of the mandible. OHRQoL and MBL measures were performed every 1 year for 5 years, while clinical measures were made every 6 months for 60 months. Data were examined using repeated ANOVA and Friedman test.ResultsThirty-seven patients had 74 implants; with mean age 56 ± 3.6 years; 43% females (n = 16) and 57% males (n = 21) accomplished the study. There were statistically significant differences in OHRQoL, MBL, and changes in soft tissue, including probing pocket depth and implant stability in 2 implants retained mandibular overdentures during 5 years follow-up periods, p ≤ 0.05.ConclusionMandibular overdentures retained by 2 implants provide a positive long-term effect on OHRQoL, MBL, probing pocket depth, and implant stability.

Silver diamine fluoride and oral health-related quality of life: A review and network meta-analysis.

ObjectiveSilver diamine fluoride (SDF) is an effective non-surgical treatment for dental caries which may also impact oral health-related quality of life (OHRQoL). The objective of this study was to conduct a network meta-analysis of SDF versus other standard of care therapies on OHRQoL.Data sourcesStudies published in PubMed/MEDLINE, Scopus, or Web of Science through July 2021 with no date or language restrictions.Study selectionAny randomized controlled trial, cohort, or case-control study that included silver diamine fluoride as either a single or combinative treatment for dental caries and a quantitatively measured outcome for oral health-related quality of life was included.Data extraction and synthesisPotentially eligible studies were screened by two independent reviewers trained in conducting systematic reviews. Studies meeting inclusion criteria underwent a full-text review with data being extracted using a standardized form, including publication details, study methodology, outcomes, assessors, and sample information. Studies underwent a risk of bias assessment. Quantitative synthesis was performed using fixed effects meta-analysis and individual comparisons were assessed via network meta-analysis.Main outcome(s) and measure(s)Oral health-related quality of life.Results19 articles were returned following search strategies. Following screening, ten studies were evaluated for full-text eligibility and five were retained for meta-analyses. Results across all treatments indicate no differences in OHRQoL when compared to SDF (SMD = -0.06, 95% CI = -0.20, 0.08). Direct and indirect estimates from network meta-analysis indicated that OHRQoL in children was not significantly different when treated with SDF versus atraumatic restorations (d = 0.02, 95% CI = -0.32, 0.36) or placebo (d = 0.03, 95% CI = -0.16, 0.22).ConclusionsEvidence from the literature consistently shows no discernible impact on OHRQoL across various non-surgical treatments for dental caries. Overall oral health-related quality of life may increase regardless of treatment protocol due to treatment of the underlying disease. Concerns over the staining of dental decay and oral mucosa resulting from treatment with silver diamine fluoride do not seem to affect OHRQoL.

The Impact on Oral Health Related Quality of Life of Orthodontic Patients with Missing Teeth Substituted with Acrylic Teeth During Orthodontic Treatment

Objective: This research aims to assess the impact on the Oral Health-Related Quality of Life (OHRQoL) in patients who had the missing teeth substituted with acrylic teeth during orthodontic treatment. Materials and Methods: Eighteen orthodontic patients aged between 18 and 35 years who had at least one missing tooth, and required prosthesis, were recruited. All patients were undergoing orthodontic treatment with fixed appliance for space opening and idealisation. Patient were randomly allocated into Group 1: Transbond XT adhesive only; Group 2: Transbond XT adhesive with surface sandblasting; Group 3: Transbond XT adhesive with surface abrasion; and Group 4: Triad Gel adhesive only. Upon achieving adequate space intraorally, the acrylic tooth was adjusted to required dimension. Subsequently, the corresponding metal bracket was attached to the labial surface using the different surface preparation prior to archwire ligation. The short version of Oral Health Impact Profile (S-OHIP-14) was used to measure the difference in OHRQoL between pre- (T0) and 6 months post-attachment (T1) of acrylic teeth. The patients were monitored monthly for six months. Results: The S-OHIP-14 for simple count (SC) and additive (ADD) scores method showed 28.3% and 40.4% improvement, respectively, although only the ADD method showed significance. Among all the domains, only the handicap domain showed the highest improvement (54.0%) which was statistically significant (p=0.001). Conclusion: There was an overall improvement in the orthodontic treatment outcome measure on the OHRQoL scores after six-months of having missing teeth substituted with acrylic teeth.

Oral health-related quality of life in children with osteogenesis imperfecta

PurposeOsteogenesis imperfecta (OI) results from mutations in the genes involved in the modification or biosynthesis of collagen. This study aimed to assess the oral health-related quality of life (OHRQoL) in children with OI.MethodologyParticipants were recruited from a highly specialised OI centre for children. The Child Oral-Health Impact Profile—Short Form (COHIP-SF) was used, adding demographic and qualitative questions. Children aged 8–16 years participated between January and October 2019. Statistical analysis was carried out. A higher COHIP-SF score indicates better OHRQoL (maximum score, 76).ResultsOne hundred and six (106) children participated (44 female, mean age 11.93 years). COHIP-SF median score was 59. Children reporting mild OI (n = 55) had higher median scores (62) compared to severe OI (n = 7) with median scores of 55 (P = 0.087). When comparing mixed (< 12 years, n = 46) and permanent dentition (≥ 12, n = 60), no significant difference in OHRQoL was seen (P = 0.977). There was no significant difference between severities for each COHIP-SF domain. Limited data on the presence of dentinogenesis imperfecta did not impact overall score (P = 0.109), but was significant in the oral-health domain (P = 0.033).QualitativeCommon themes were the need for braces, discolouration, pain and function.ConclusionThis study confirmed that children with OI have dental concerns in areas including oral health, functional well-being and socio-emotional well-being. This was related to severity of OI.

Examining the effectiveness of different dental recall strategies on maintenance of optimum oral health: the INTERVAL dental recalls randomised controlled trial.

Objective To compare the clinical effectiveness of different frequencies of dental recall over a four-year period.Design A multi-centre, parallel-group, randomised controlled trial with blinded clinical outcome assessment. Participants were randomised to receive a dental check-up at six-monthly, 24-monthly or risk-based recall intervals. A two-strata trial design was used, with participants randomised within the 24-month stratum if the recruiting dentist considered them clinically suitable. Participants ineligible for 24-month recall were randomised to a risk-based or six-month recall interval.Setting UK primary dental care.Participants Practices providing NHS care and adults who had received regular dental check-ups.Main outcome measures The percentage of sites with gingival bleeding on probing, oral health-related quality of life (OHRQoL), cost-effectiveness.Results In total, 2,372 participants were recruited from 51 dental practices. Of those, 648 were eligible for the 24-month recall stratum and 1,724 participants were ineligible. There was no evidence of a significant difference in the mean percentage of sites with gingival bleeding on probing between intervention arms in any comparison. For those eligible for 24-month recall stratum: the 24-month versus six-month group had an adjusted mean difference of -0.91%, 95% CI (-5.02%, 3.20%); the 24-month group versus risk-based group had an adjusted mean difference of 0.07%, 95% CI (-3.99%, 4.12%). For the overall sample, the risk-based versus six-month adjusted mean difference was 0.78%, 95% CI (-1.17%, 2.72%). There was no evidence of a difference in OHRQoL (0-56 scale, higher score for poorer OHRQoL) between intervention arms in any comparison. For the overall sample, the risk-based versus six-month effect size was -0.35, 95% CI (-1.02, 0.32). There was no evidence of a clinically meaningful difference between the groups in any comparison in either eligibility stratum for any of the secondary clinical or patient-reported outcomes.Conclusion Over a four-year period, we found no evidence of a difference in oral health for participants allocated to a six-month or a risk-based recall interval, nor between a 24-month, six-month or risk-based recall interval for participants eligible for a 24-month recall. However, patients greatly value and are willing to pay for frequent dental check-ups.Zusatzmaterial online: Zu diesem Beitrag sind unter 10.1038/s41415-021-2612-0 für autorisierte Leser zusätzliche Dateien abrufbar.

A Nationwide Survey of Oral Health Related Quality of Life of Children With Orofacial Cleft in New Zealand.

To describe (1) oral health related quality of life (OHRQoL) for children with orofacial cleft (OFC) in New Zealand and (2) assess any differences in OHRQoL by sex, ethnicity, and cleft phenotype using the 16 item (and 8 item subset) of the Child Perception Questionnaire (CPQ) and Parent version (P-CPQ). Prospective cross-sectional nationwide study. Children with OFC and their parents completed the 16-item CPQ or the Parent CPQ, respectively, when attending cleft clinic appointments between January 2015 and December 2017. Overall, 174 children (mean age 10.4 ± 1.2 years) and their parents (n = 181) completed the CPQ or P-CPQ. In multivariable analysis, neither the CPQ nor P-CPQ 16-item or 8-item subset showed significant differences in OHRQoL total score with cleft phenotype. Children with cleft lip and palate (CLP) had higher (worse) well-being scores than those with cleft palate alone (CP) on the P-CPQ. Pacific Island children had consistently higher scores across both CPQ and P-CPQ, total and subscales. Significant differences in OHRQoL among children with OFC were found for the well-being domain for children with CLP as reported by P-CPQ, but the symptom domain and total score showed no differences. Poorer scores were reported for children of Pacific Island descent using both questionnaires. The study findings indicate that children with OFC in New Zealand are a group who experience worse OHRQoL when referenced to normative non-OFC data. Further investigations are required to establish greater insight into specific factors influencing OHRQoL.

Is there an association between oral health-related quality of life and Alzheimer's disease?

Data sources PubMed, Medline, Embase, CINAHL, Cochrane Library database and ProQuest databases were searched.Study selection Observational and non-randomised studies in English language were considered for inclusion. Two reviewers independently selected the relevant studies. Any disagreement was resolved by discussion with a third reviewer. The outcome of interest for this review was oral health-related quality of life (OHRQoL) in patients with Alzheimer's disease.Data extraction and synthesis Data extraction was conducted independently by two reviewers. Critical appraisal was conducted by two reviewers using the Joanna Briggs Institute 'Meta-Analysis of Statistics Assessment and Review Instrument'.Results Six studies were included in the review, of which five were cross-sectional and one was a non-randomised controlled trial. OHRQoL was measured by the Oral Health Impact Profile (OHIP) in one study and the Geriatric Oral Health Assessment Index (GOHAI) in the other five included studies. All six studies were judged as methodologically strong. When the results of four studies which used the GOHAI were pooled together in a meta-analysis, no statistically significant differences in the GOHAI scores between patients with Alzheimer's disease and controls were found (SMD = 0.09; 95%CI: -0.66 to 0.85).Conclusions The results of this review showed no significant difference in OHRQoL between patients with Alzheimer's disease and healthy controls.

Does the Clinical Form of Oral Lichen Planus (OLP) Influence the Oral Health-Related Quality of Life (OHRQoL)?

(1) Background: The aim of the study was to investigate the oral health–related quality of life (OHRQoL) of patients with oral lichen planus (OLP) and to evaluate differences between the various clinical forms of OLP. Specifically, the differences in OHRQoL, physical pain levels and eating restriction were assessed; (2) Methods: One hundred and twelve patients with clinical and histological features of OLP from the Department of Cranio-Maxillofacial Surgery of the Münster University Hospital participated in this prospective study. OHRQoL was analysed by using the German short version of the Oral Health Impact Profile (OHIP-14). Physical pain levels and restriction in eating were rated on visual analogue scales (VAS). The statistical analysis was performed using the Mann–Whitney U-Test and the chi-squared test with a significance level at p = 0.05; (3) Results: Group 1 consisted of patients with reticular OLP (n = 50) and group 2 of patients with atrophic, erosive-ulcerative or bullous OLP (n = 62). The average OHIP-14 score was 13.54 points and differed significantly between the two groups. There were significant differences in the domains “physical pain”, “psychological discomfort”, “physical disability” and “social disability”. The VAS “physical pain” score and “restriction in eating” score varied significantly between the clinical forms. Positive correlations were found between the OHIP-14 total scores and the VAS scores; (4) Conclusion: The OHRQoL is significantly limited in patients with OLP; especially, patients with erosive-ulcerative OLP are affected.

Oral Health Related Quality of Life (OHRQoL) outcomes at the time of orthodontic appliance removal and three months into retention

Abstract Background Oral health-related quality of life (OHRQoL) has become an important measure of orthodontic treatment outcome. However, it is unclear how long OHRQoL benefits manifest themselves following the removal of the orthodontic appliances. Objectives To investigate differences in OHRQoL recorded at the time of orthodontic appliance removal and three months into retention. Setting and sample Described is a prospective outcome study of 59 consecutive participants treated in a hospital-based clinic between 2015 and 2018. The patients comprised three groups: those who received orthognathic surgery (N = 15), those who had an orofacial cleft (N = 30) and those who had no-surgery/no-cleft (N = 14). Each individual completed an age-specific OHRQoL questionnaire that categorised them as either an adolescent (N = 37) or an adult (N = 22) participant. Method The OHRQoL questionnaires were completed at the time of appliance removal (T0) and again three months into retention (T1). The Child Perceptions Questionnaires (CPQ11-14-ISF8 and P-CPQ8) were used for adolescent participants and their parent/caregiver, respectively, while the short-form Oral Health Impact Questionnaire (OHIP-14) was used for the adults. Results The OHIP-14, CPQ11-14-ISF8 and P-CPQ8 detected improvements in overall and domain scores between T0 and T1 for all patient groups. Moderate effect sizes (0.2–0.7) were observed in all the domain, overall and group mean scores. Conclusions Post-treatment orthodontic OHRQoL outcomes improve over the three-month period following appliance removal. The use of these measures should be delayed beyond the immediate time of appliance removal to allow the benefits of orthodontic treatment to be appreciated.

Patient satisfaction and oral health-related quality of life (OHRQoL) of conventional denture, fixed prosthesis and milled bar overdenture for All-on-4 implant rehabilitation. A crossover study.

This study aimed to evaluate patient satisfaction and oral health-related quality of life (OHRQoL) of conventional denture, fixed prosthesis and milled bar overdenture for All-on-4 implant rehabilitation. Sixteen completely edentulous patients with ill-fitted mandibular dentures received new mandibular dentures (CDs). After 3months, 4 implants were installed according to the "All-on-4 concept" and immediately loaded with mandibular dentures. Three months after osseointegration, patients received either fixed prosthesis (FP) or milled bar overdenture (MB) in a crossover design. Patient satisfaction was evaluated using a visual analog scale (VAS). OHRQoL was evaluated using the OHIP-14. Questionnaires of VAS and OHIP-14 were measured 3months after wearing each of the following prostheses: CD, FP, and MB. For all questions of VAS and OHIP-14, CD showed significant lower satisfaction compared to FP and MB (p<.00025). FP recorded significant higher VAS scores than MB regarding retention and stability (p<.00007). MB recorded significant higher scores than FP regarding general satisfaction, comfort, ease of cleaning, and handling (p<.00008). Regarding OHIP-14, no significant differences in OHIP scores between FP and MB were observed for all domains of OHIP. "All-on-4" implant rehabilitation of edentulous mandible with FP and MB achieves high patient satisfaction and OHRQoL compared to CD. No significant difference in OHRQoL between FP and MB was observed. Regarding VAS, FP rated greater satisfaction with retention, stability, and chewing compared to MB. However, MB rated greater satisfaction with ease of cleaning and handling compared to FP.

Oral health-related quality of life, oral aesthetics and oral function in head and neck cancer patients after oral rehabilitation.

Head and neck cancer (HNC) is diagnosed in more than 500000 patients every year worldwide with increasing prevalence. Oral rehabilitation is often needed after HNC treatment to regain oral function, aesthetics and oral health-related quality of life (OHRQoL). The objectives were to evaluate OHRQoL, oral aesthetics and oral function after oral rehabilitation in HNC patients and compare it to that of non-HNC patients. Eighteen patients treated for HNC who subsequently had oral rehabilitation (2014-2017), and a control group of eighteen age- and gender-matched non-HNC patients treated with removable prostheses (2014-2018) were included in a cross-sectional study. The OHRQoL was assessed by the Oral Health Impact Profile 49 questionnaire (OHIP-49), the oral aesthetics by the Prosthetic Esthetic Index (PEI) and the Orofacial Esthetic Scale (OES), and the oral function by the Nordic Orofacial Test-Screening (NOT-S). The HNC patients had worse oral function and OHRQoL than the control patients (mean NOT-S score 4.56 vs 0.56, P<0.01 and mean OHIP-49 score 42.50 vs 20.94, P=0.050). When including number of replaced teeth and type of prosthesis in the tests, no significant difference in OHRQoL was found between the groups. No difference was found in the overall aesthetic outcomes (mean PEI total score 32.28 vs 30.67, P=0.367 and mean OES total score 48.78 vs 53.56, P=0.321). Multiple regression analyses showed that being HNC patient compared to control patient impaired the oral function. Oral function is significantly impaired in HNC patients compared to non-HNC patients after oral rehabilitation.

Oral Health-Related Quality of Life in Native and Immigrant Populations in the PELFI Study in Spain.

Quality of life and its relationship to oral health is an important consideration in the determinants of health of vulnerable groups. The aim of this study is to assess oral health-related quality of life (OHRQoL) and its related factors in native and immigrant population families from the Platform of Longitudinal Studies on Immigrant Families (PELFI) study in Spain. A cross-sectional study was conducted in a sample of 401 adults aged 18 years and older from Spain, Ecuador, Colombia, and Morocco. The OHIP-14 instrument was applied, and three summary variables were used (prevalence, extent, and severity). Sociodemographic and self-perceived health variables were included. Bivariate analyzes were carried out to summarize the variables of the OHIP-14 according to sociodemographic and health variables, and bivariate analyzes of the OHIP-14 dimensions was conducted by country of origin. Multivariate linear models were used to investigate predictors for the dimensions of the OHIP-14. Multivariate logistic models were used to estimate the association of OHRQoL with immigration status using crude and adjusted odds ratios with 95% confidence intervals (OR-95% CI). It was found that 14.8% of men and 23.8% of women reported negative impacts in terms of OHRQoL (statistically significant differences: p < 0.05). There were statistically significant differences according to the country of origin in the prevalence and severity outcomes of the OHIP-14 in women (p < 0.05), and severe outcomes were observed in Moroccan women. In women, statistically significant differences (p < 0.05) in OHRQoL were observed according to age and marital status. There were some differences between OHIP-14 summary outcomes according to the health variables. Some sociodemographic and health variables were predictors for the OHIP-14 and their dimensions with differences by sex. Multivariate analysis showed a statistically significant association between OHRQoL and immigration status for Moroccan women. Differences in OHRQoL were found according to sociodemographic and health variables. Further research could clarify the predictors of OHRQoL through epidemiological surveillance and longitudinal studies.

Associations between symptoms of temporomandibular disorders, quality of life and psychological states in Asian Military Personnel.

Symptoms of Temporomandibular Disorders (TMD) could affect oral health-related quality of life (OHRQoL) and psychological distress. This study aims to determine the prevalence of TMD symptoms, and impact of type and number of TMD symptoms on OHRQoL and psychological states among Asian military personnel. The study was conducted across 12 military dental centres using self-administered questionnaire comprising demographical data, DC/TMD symptom questionnaire, OHIP-14 and DASS-21. A total of 3028 personnel, aged between 18-65years old, were invited to participate with an acceptance rate of 90.5%. Data analysis was done using non-parametric tests, regression analysis and Spearman correlation (P<0.05). Out of 2043 subjects (1998 males; 45 females, mean age 24.18±7.18years), 36.32% (n=742) reported at least one TMD symptom. Significant differences in summary OHIP-14, depression, anxiety and stress scores were observed between subjects with and without TMD symptoms. Significant differences in OHIP-14 and DASS-21 scores were observed between dissimilar type and number of TMD symptoms in the TMD group. Those with headaches and 2-3 symptoms have substantially poorer OHRQoL and greater psychological distress. Associations between number of TMD symptoms, quality of life, depression, anxiety and stress were significant but weak (r=0.19-0.40). Symptoms of Temporomandibular Disorders were prevalent among Asian military population. Significant differences in OHRQoL and psychological states were observed between subjects with and without TMD symptoms. Specific type and number of TMD symptoms impacted OHRQoL and psychological states differently. Associations between number of TMD symptoms and quality of life, depression, anxiety and stress were significant but weak.

Oral health-related quality of life of children and adolescents with and without migration background in Germany.

To compare oral health-related quality of life (OHRQoL) in children and adolescents with and without migration background, and to assess whether potential differences in OHRQoL can be sufficiently explained by oral health characteristics. A consecutive sample of 112 children and adolescents was recruited in a German university-based orthodontic clinic, and a convenience sample of 313 children and adolescents of German public schools was enrolled in the study (total N = 425, age range 7-17years). However, 29 participants were excluded due to insufficient information regarding migration background. Accordingly, the non-migrant group consisted of 262 participants (61.6%). For children with migration background, two groups were classified: (i) one parent born in a foreign country (N = 41, 9.6%, single-sided migration background), and (ii) both parents and/or child born in a foreign country ( N= 93, 21.9%, double-sided migration background). OHRQoL was assessed using the German 19-item version of the Child Oral Health Impact Profile (COHIP-G19). Additionally, physical oral health of 269 children with classified migration background was determined in a dental examination. Overall, OHRQoL was significantly lower in the group with double-sided migration background indicated by lower COHIP-G19 summary scores (mean: 58.6 points) than in the group with single-sided migration background (mean: 63.3 points) or the non-migrant group (mean: 63.2 points). Likewise, the summary scores of the subscale "oral health well-being" and the subscale "social/emotional, school, and self-image" were also lower in the double-sided migrant group than in the other two groups. Linear regression analysis showed an association between double-sided migration background and impaired OHRQoL, even after statistically controlling for demographic, socioeconomic, and oral health characteristics. Children and adolescents with double-sided migration background have poorer OHRQoL than comparably aged migrants with single-sided migration background or non-migrations. Between-group differences in OHRQoL could not be sufficiently explained by effects of socioeconomic status or physical oral health characteristics. Thus, other methodological, cultural, or immigration-related factors might also play an important role for the observed effects.

Impact of oral clefts on the oral health-related quality of life of preschool children and their parents.

To assess the oral health-related quality of life (OHRQoL) of preschool children with cleft lip and palate (CLP) and their relatives. In this cross-sectional study, 55 2-5-year-old children with the history of CLP were randomly selected from those referred to Shiraz Lip and Palate Cleft Research Center and treated with single-stage closure (Push back palatoplasty). Furthermore, same number of children with the same age who attended the Shiraz School of Dentistry for routine dental care were selected as control group using randomized sampling. Children's demographic data were obtained from their parents. Farsi version of the Early Childhood Oral Health Impact Scale (F-ECOHIS) was used for evaluating these children's QoL. We found a significant difference in OHRQoL between children with CLP and children without CLP in the overall score of F-ECOHIS and all of subscales. In the impact on children subscale, the difference between these groups was remarkable in limitations' domain. As for difficulties faced by children, question on "difficulty in pronouncing words" had the highest average score. Furthermore, in impact on family, in parental distress domain, the difference between these groups was remarkable. For difficulties faced by family, financial impact got the highest average score. No significant difference was found between boys and girls with CLP in all subscales. While according to the score of total F-ECOHIS in unilateral and bilateral CLP children, there was statistically significant difference in these groups. Since oral clefts affect the QoL of children and their families even after the usual treatments, the implementation and maintenance of multidisciplinary interventional strategies are required for establishment of facial esthetics, oral function, and psychological support for such individuals.

Rural-urban disparity in oral health-related quality of life.

The objective of this population-based cross-sectional study was to estimate rural-urban disparity in the oral health-related quality of life (OHRQoL) of the Quebec adult population. A 2-stage sampling design was used to collect data from the 1788 parents/caregivers of schoolchildren living in the 8 regions of the province of Quebec in Canada. Andersen's behavioural model for health services utilization was used as a conceptual framework. Place of residency was defined according to the Statistics Canada Census Metropolitan Area and Census Agglomeration Influenced Zone classification. The outcome of interest was OHRQoL measured using the Oral Health Impact Profile (OHIP)-14 validated questionnaire. Data weighting was applied, and the prevalence, extent and severity of negative oral health impacts were calculated. Statistical analyses included descriptive statistics, bivariate analyses and binary logistic regression. The prevalence of poor oral health-related quality life (OHRQoL) was statistically higher in rural areas than in urban zones (P = .02). Rural residents reported a significantly higher prevalence of negative daily-life impacts in pain, psychological discomfort and social disability OHIP domains (P < .05). Additionally, the rural population showed a greater number of negative oral health impacts (P = .03). There was no significant rural-urban difference in the severity of poor oral health. Logistic regression indicated that the prevalence of poor OHRQoL was significantly related to place of residency (OR = 1.6; 95% CI = 1.1-2.5; P = .022), perceived oral health (OR = 9.4; 95% CI = 5.7-15.5; P < .001), dental treatment needs factors (perceived need for dental treatment, pain, dental care seeking) (OR = 8.7; 95% CI = 4.8-15.6; P < .001) and education (OR = 2.7; 95% CI = 1.8-3.9; P < .001). The results of this study suggest a potential difference in OHRQoL of Quebec rural and urban populations, and a need to develop strategies to promote oral health outcomes, specifically for rural residents. Further studies are needed to confirm these results.
