Difference In Oral Health-related Quality Research Articles

Clinical outcomes of milled, 3D-printed, and conventional complete dentures in edentulous patients: A systematic review and meta-analysis.

This systematic review aims to compare clinical outcomes of digital dentures with conventional dentures. This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and was registered in Prospero. The formulated population, intervention, comparison, outcome (PICO) question was "What is the clinical outcome of digital versus conventional complete dentures (CDs) in edentulous patients?". The search strategy used three main electronic databases and an additional manual search was completed in August 2023 by following an established search strategy. Initial inclusion was based on titles and abstracts, followed by a detailed review of selected studies, and clinical studies that evaluated the clinical outcome of digital (milled or 3D-printed) versus conventional CDs were included. A qualitative analysis for clinical studies was used to assess the risk of bias. The certainty of the evidence was assessed according to the grading of recommendations, assessment, development, and evaluations (GRADE) system. In addition, a single-arm meta-analysis was performed to evaluate the retention between digital versus conventional CDs. The initial search yielded a total of 947 articles, out of which 19 were selected for a comprehensive review, and six met the eligibility criteria to be included in this systematic review. The computer-aided design and computer-aided manufacturing (CAD-CAM) CDs showed increased retention, no relevant differences in oral health-related quality of life (OHRQoL), and shorter working time compared to conventional dentures. Two studies were eligible for meta-analysis; retention was significantly better among CAD-CAM fabricated dentures (standardized mean difference [SMD] 0.501) than conventional dentures. The heterogeneity between studies was high (95% CI: 0.049-0.952). Clinically, both the milled and the 3D-printed CD fared better than conventional dentures in terms of retention, reduction in the number of appointments, improved patient comfort, and improved predictable maintenance of the denture. Patients' perceptions and satisfaction were independent of the digital and conventional fabricated dentures.

Assessing oral health and the minimally important differences in oral health-related quality of life of non-diabetic and diabetic patients: a cross-sectional study.

Non-diabetics and diabetics might have different oral health problems and impacts on their oral health-related quality of life (OHRQoL). Comparison of oral health status and coping strategies between these patients, and evaluation of factors associated with OHRQoL might facilitate better treatment planning for improved patient-centred outcome. One hundred and eleven non-diabetics and 107 diabetics attending a public hospital were clinically examined and evaluated for coping strategies (abbreviated coping orientation to problems experienced) and OHRQoL [short-form oral health impact profile (OHIP-14S)]. Factors associated with OHRQoL were analysed through correlation/partial correlation. Minimally important differences (MID) of OHIP-14S were calculated to confirm associations between attachment loss, caries, and tooth loss with OHRQoL. Non-diabetics had worse periodontal status. Diabetics had more missing teeth. Non-diabetics and diabetics employed maladaptive coping to manage oral health problems. Overall, non-diabetics reported worse OHRQoL. Determination of MID showed that non-diabetics with high-severe attachment loss and <20 teeth experienced poorer OHRQoL. Diabetics with caries, high-severe attachment loss, and <25 teeth experienced poorer OHRQoL. Different factors were associated with OHRQoL of non-diabetics and diabetics. Delivery of treatment aimed at maintaining teeth in a periodontally healthy and caries free state, and provision of more chewing units might help improve OHRQoL of diabetics. © 2024 Australian Dental Association.

Risk factors associated with periodontal disease and its impact on quality of life among pregnant women

Background Periodontal disease during pregnancy affects maternal oral health and increases the risk of adverse pregnancy outcomes. However, studies on the risk factors for periodontal disease and its impact on oral health-related quality of life in pregnant women in Taiwan are lacking. This present study aimed to identify the risk factors associated with periodontal disease during pregnancy and examine the relationship of periodontal disease with oral health-related quality of life among pregnant women. Methods This study was conducted in a large medical centre in northern Taiwan. Eighty-four participants completed a periodontal examination by dentists as well as structured questionnaires, including the Oral Health Impact Profile-14, demographics, obstetric history, dietary habits, and oral hygiene behaviours. Multivariate logistic regression was used to determine the risk factors associated with periodontal disease and a t-test was used to compare the difference in oral health-related quality of life between pregnant women with and without periodontal disease. Results Fifty participants (59.5%) had periodontal diseases. Risk factors for periodontal disease included eating out for lunch, consuming beverages, brushing less than three times per day, and not receiving regular professional dental cleanings. The oral health-related quality of life was significantly poorer in pregnant women with periodontal disease than in those without. Conclusions The risk factors for periodontal disease, including eating out for lunch, drinking beverages, brushing teeth less, and not regular dental cleaning, provide convincing evidence for pregnant women to maintain good oral hygiene to prevent periodontal disease and improve oral health-related quality of life.

Minimally important differences in oral health-related quality of life after fixed orthodontic treatment: a prospective cohort study.

The minimally important difference (MID, the smallest difference that patients perceive as beneficial) has been proposed to assess whether study results are clinically meaningful, reducing the shortcoming of P-values-based approaches in the assessment of clinical outcomes. The post-treatment changes and the MID in Oral Health-Related Quality of Life (OHRQoL) among adults undergoing fixed orthodontic treatment were investigated. Ninety-two patients (29.1 ± 6.3 years old, 18 males and 74 females) were prospectively included. Oral Health Impact Profile (OHIP-14) and United Kingdom Oral Health-related Quality of Life (OHQoL-UK) were used to assess OHRQoL at baseline and post-treatment (50.8 ± 15.7 months). Global Transition Rating (GTR) was used to assess oral health/well-being, Peer Assessment Review (PAR), and Index of Complexity, Outcome and Need (ICON) were used to assess occlusion. Wilcoxon signed-rank test was used to assess changes in OHRQoL and occlusion, Kruskal-Wallis one-way ANOVA and Mann-Whitney U-test were used to assess associations between OHRQoL and oral health/well-being or occlusion. MID for OHIP-14 and OHQoL-UK was estimated via anchor-based (PAR, ICON, GTR) and distribution-based approach (effect size, standardized response mean, standard error of measurement). The median OHIP-14 and OHQoL-UK post-treatment scores were significantly changed, indicating improved OHRQoL. Based on the agreement between different methods, the MID of OHIP-14 and OHQoL-UK were at least 15 and 6 scale points, corresponding to a large effect size (1.5-1.7). Orthodontic treatment had a positive long-term impact on OHRQoL. MID for the OHIP-14 and OHQoL-UK provide guidance to interpreting the impact of orthodontic treatment on the OHRQoL of patients.

Differences in Oral Health-Related Quality of Life (OHRQoL) among the Elderly Population in Rembang Regency

Epidemiological studies have shown that several factors, such as age, gender, tooth loss, socioeconomic status, cultural background, psychological stress of dental visit, and smoking can influence OHRQoL. Oral health is strongly age dependent, therefore OHRQoL differences are predicted to exist in the elderly group according to WHO. This condition is especially true for Rembang Regency due to the high population of the elderly and the shared ignorance on oral health given an overemphasis on other priorities, which will have an impact on their quality of life. The objective of this study is to know the OHRQOL difference in the elderly group in Rembang Regency with cross-sectional design. The research subjects were selected by inclusion and exclusion criteria with online informed consent. The questionnaire related to age and GOHAI was distributed and filled out online. Data were processed and analyzed using the Kruskall Wallis followed by Mann-Whitney post-hoc analysis and multiple linear regression test. A total of 222 respondents were involved (n= 222) consisting of 102 male and 120 female. The majority level of their OHRQoL were moderate (65.3%). The most affected dimension was physical function since it limits the type or amount of food intake (30.4%). The Kruskall-Wallis test showed significant OHRQoL differences in middle-age, elderly, old, and very old groups (p&lt;0.05). The OHRQoL difference between middle-age and old and middle-age and very old obtained a significant result in the Mann-Whitney post hoc test with p value &lt;0.05. Multiplelinear regression test showed a significant effect of age on OHRQoL with tooth loss as a confounding variable. Thus, Oral Health Related Quality of Life (OHRQoL) of the elderly group is significantly different.

Effect of physical and psychological status on oral health quality of life of geriatric patients undergoing complete denture treatment.

The present study was conducted to evaluate differences in Oral Health-Related Quality of Life (OHRQoL) in denture wearers based on psychological classification and patient satisfaction. A prospective study. 284 patients, aged 30 years and above who fulfilled the eligibility criteria were recruited. Participants answered the OHIP - EDENT questionnaire at the time of denture insertion and 6 months later. Psychological categorization was based on MM House classification. Patient satisfaction was graded from totally satisfied to not very satisfied. SPSS 23 version was used for analyzing descriptive and inferential statistics. ANOVA was used to find significant differences for OHRQoL based on psychological classification and patient satisfaction. Before and after intervention analysis was assessed using student 't' test. Philosophical and exacting patients had better adaptation to dentures than the hysterical and indifferent class of denture wearers. Totally satisfied and very satisfied patients with dentures had lesser mean scores as against the other categories which was significant in all domains suggesting better. Overall, OHIP - EDENT score decreased from 20.253 ± 12.466 to 17.168 ± 14.143, which were significant at P =0.043, thus showing an improvement after a 6 month follow up. Psychological attitude of denture wearers must be considered by the prosthetic specialist for effective adaptation and acceptance by the edentulous patient.

Comparison of two survey instruments measuring quality of life in pediatric dentofacial patients.

(1) To assess the effectiveness of the Orthognathic Quality of Life Questionnaire (OQLQ) and the Child Oral Health Impact Profile (COHIP) to detect differences in Oral Health-Related Quality of Life (OHRQoL) between pediatric patients with dentofacial deformities and controls. (2) To assess for correlations between scores from the OQLQ and COHIP domains with the type and severity of the skeletal mal-relationship. (3) To assess if the COHIP and OQLQ were identifying unique or overlapping OHRQoL concerns. Subjects were under age 18, presented with a dentofacial deformity, and completed both surveys. Matched controls completed the same. Severity for conditions was recorded via overjet, overbite, and ANB values and subjects were classified as skeletal Class I, II, or III. Enrollment yielded 30 subjects and 31 controls. For the OQLQ, significant differences between subjects and controls were found for the Facial Esthetics domain, Oral Function domain, and total score. For the COHIP, significant differences were found for the Social/Emotional Well-Being and Self-Image domains plus total score. There were no significant correlations between the severity of the condition as measured by overjet and reported OHRQoL for any domains. The OQLQ and COHIP are effective at detecting significant OHRQoL differences between pediatric patients with dentofacial deformities and controls. Although there is some overlap in the results, the instruments appear to identify different OHRQoL concerns.

Risk-based, 6-monthly and 24-monthly dental check-ups for adults: the INTERVAL three-arm RCT.

Traditionally, patients are encouraged to attend dental recall appointments at regular 6-month intervals, irrespective of their risk of developing dental disease. Stakeholders lack evidence of the relative effectiveness and cost-effectiveness of different recall strategies and the optimal recall interval for maintenance of oral health. To test effectiveness and assess the cost-benefit of different dental recall intervals over a 4-year period. Multicentre, parallel-group, randomised controlled trial with blinded clinical outcome assessment at 4 years and a within-trial cost-benefit analysis. NHS and participant perspective costs were combined with benefits estimated from a general population discrete choice experiment. A two-stratum trial design was used, with participants randomised to the 24-month interval if the recruiting dentist considered them clinically suitable. Participants ineligible for 24-month recall were randomised to a risk-based or 6-month recall interval. UK primary care dental practices. Adult, dentate, NHS patients who had visited their dentist in the previous 2 years. Participants were randomised to attend for a dental check-up at one of three dental recall intervals: 6-month, risk-based or 24-month recall. Clinical - gingival bleeding on probing; patient - oral health-related quality of life; economic - three analysis frameworks: (1) incremental cost per quality-adjusted life-year gained, (2) incremental net (societal) benefit and (3) incremental net (dental health) benefit. A total of 2372 participants were recruited from 51 dental practices; 648 participants were eligible for the 24-month recall stratum and 1724 participants were ineligible. There was no evidence of a significant difference in the mean percentage of sites with gingival bleeding between intervention arms in any comparison. For the eligible for 24-month recall stratum: the 24-month (n = 138) versus 6-month group (n = 135) had an adjusted mean difference of -0.91 (95% confidence interval -5.02 to 3.20); the risk-based (n = 143) versus 6-month group had an adjusted mean difference of -0.98 (95% confidence interval -5.05 to 3.09); the 24-month versus risk-based group had an adjusted mean difference of 0.07 (95% confidence interval -3.99 to 4.12). For the overall sample, the risk-based (n = 749) versus 6-month (n = 737) adjusted mean difference was 0.78 (95% confidence interval -1.17 to 2.72). There was no evidence of a difference in oral health-related quality of life between intervention arms in any comparison. For the economic evaluation, under framework 1 (cost per quality-adjusted life-year) the results were highly uncertain, and it was not possible to identify the optimal recall strategy. Under framework 2 (net societal benefit), 6-month recalls were the most efficient strategy with a probability of positive net benefit ranging from 78% to 100% across the eligible and combined strata, with findings driven by the high value placed on more frequent recall services in the discrete choice experiment. Under framework 3 (net dental health benefit), 24-month recalls were the most likely strategy to deliver positive net (dental health) benefit among those eligible for 24-month recall, with a probability of positive net benefit ranging from 65% to 99%. For the combined group, the optimal strategy was less clear. Risk-based recalls were more likely to be the most efficient recall strategy in scenarios where the costing perspective was widened to include participant-incurred costs, and in the Scottish subgroup. Information regarding factors considered by dentists to inform the risk-based interval and the interaction with patients to determine risk and agree the interval were not collected. Over a 4-year period, we found no evidence of a difference in oral health for participants allocated to a 6-month or a risk-based recall interval, nor between a 24-month, 6-month or risk-based recall interval for participants eligible for a 24-month recall. However, people greatly value and are willing to pay for frequent dental check-ups; therefore, the most efficient recall strategy depends on the scope of the cost and benefit valuation that decision-makers wish to consider. Assessment of the impact of risk assessment tools in informing risk-based interval decision-making and techniques for communicating a variable recall interval to patients.

Gender-wise comparison of oral health-related quality of life and its relationship with periodontal status among the Indian elderly.

Aim:The aim of this study is to assess if there are any gender differences in oral health-related quality of life (OHRQoL) and periodontal status among the elderly population of Haryana.Materials and Methods:A cross-sectional study was conducted among 1200 geriatric population of Faridabad district of Haryana. Subjects were selected by a combination of systematic, cluster, and multistage sampling techniques. Primary, secondary, and tertiary sampling units were chosen as wards, areas, and households, respectively.Self-Administered Questionnaire:Geriatric oral health assessment index was used to assess the OHRQoL among males and females. Periodontal status was assessed using the World Health Organization oral health survey pro forma with some modifications.Results:Results were analyzed using the Statistical Package for the Social Sciences 21 software. Gender-wise association of periodontal status with OHRQoL revealed a significant association with mobile teeth (P < 0.05). No relation was seen between OHRQoL, gingival bleeding, periodontal pocket, and loss of attachment (P > 0.05).Conclusion:No significant differences were observed in periodontal status among males and females, but OHRQoL was found to be better among males than females. Indian policymakers can use the conclusion derived from this study for planning and implementing public oral health strategies for the geriatric population.

Parent’s report on oral health‐related quality of life of children with haemophilia

Among children with haemophilia and their caregivers; problems arising from the teeth and the surrounding tissues have an important role in the treatment of this disease and it affects the quality of life of children and their parents. Aim of this study is to evaluate the oral health-related quality of life of children with haemophilia from the perspective of their parents. Paediatric oral health-related quality of life (POQL) instrument was used in this cross-sectional study for quality of life measurement. The research data collected by the questionnaire form were coded for scale items and personal information questions and transferred to SPSS, a multivariate statistical analysis program for social sciences. SPSS 23.0 (IBM Corp, Armonk, NY) package program was used for statistical analysis of the data. Primary dentition dmft scores of patients with haemophilia are higher than the control group; mean value of haemophilic group is 3.5 vs control group are 2.6, respectively (P=0.034). In spite of higher dmft scores, the haemophilia and control groups have shown no significant difference in oral health-related quality of life scores; median scores were 63.9 in haemophilic group and 85.3 in control group (P=0.336), respectively. In spite of lower oral health measures, children with haemophilia and their parents reported no difference in oral health-related quality of life from their healthy counterparts.

Impact of skeletal divergence on oral health-related quality of life and self-reported jaw function.

ObjectiveTo investigate the differences in oral health-related quality of life (OHRQoL) and self-reported jaw function between patients with hyperdivergent and normodivergent facial types.MethodsEighty patients with a distinctively hyperdivergent facial type (mandibular plane angle greater than 2 standard deviations, or 42°) and 80 controls were individually matched according to age, sex, ethnicity, and treatment stage. Data were collected using self-report questionnaires such as the Oral Health Impact Profile (OHIP-14) and Jaw Functional Limitation Scale (JFLS-8).ResultsThe mean age of the patients was 17.2 ± 4.6 years (range, 12–9 years), with most (65.0%) being female and of New Zealand European origin (91.3%). Individuals with hyperdivergent facial types had higher overall and social domain scores on the OHIP-14 (p < 0.05) than did the ones with normodivergent facial types. However, the intergroup differences in JFLS-8 scores were not significant (p > 0.05).ConclusionsJaw function appears to be similar in individuals with hyperdivergent and normodivergent facial morphologies. However, those with hyperdivergent facial types are more likely to self-report poorer OHRQoL than are those with normal faces, especially in relation to social aspects.

Oral health impact of halitosis in Chinese adults.

To compare differences in oral health-related quality of life (OHRQoL) between halitosis and non-halitosis patients and to explore relationships between halitosis and OHRQoL. Patients who visited the halitosis clinic at the Ninth People's Hospital and were diagnosed with halitosis were included in the halitosis group. The control group consisted of patients without halitosis. All participants were assessed for halitosis (volatile sulphur compound measurements with a portable sulphide monitor, Oral Chroma and organoleptic tests), underwent a clinical oral examination (dental caries status and periodontal condition) and completed a questionnaire. Oral health-related quality of life was measured using the Oral Health Impact Profile (OHIP-14, Chinese version). A total of 204 patients (102 halitosis and 102 controls) were included. The halitosis group had significantly higher OHIP-14 scores (severity) than the control group (15.7 versus 7.9, P < 0.001). The mean number of items with negative impact (extent) was significantly different between the halitosis and control groups (1.8 versus 0.3, P < 0.001). Around 56% of participants in the halitosis group reported at least one item with 'fairly often' or 'very often' (prevalence), while 21% did so in the control group (P < 0.001). In halitosis patients, the most commonly reported negative impacts were within the domains of 'psychological discomfort' and 'psychological disability'. Oral health-related quality of life status was significantly poorer in halitosis patients than in non-halitosis patients. Halitosis patients may experience some degree of psychological discomfort and disability.

Racial Differences in Oral Health-Related Quality of Life: A Multilevel Analysis in Brazilian Children.

This cross-sectional study aimed to assess the influence of race/ethnicity on Brazilian children' oral health-related quality of life (OHRQoL). A multistage random sampling selected a representative sample of 1,134 twelve-years-old children from public schools of Santa Maria, a city in Southern Brazil. Participants were examined by 4 calibrated clinicians (minimum Kappa-value for inter-examiner agreement of 0.8) and the Brazilian short version of the Child Perceptions Questionnaire (CPQ11-14) was administered. The children's parents or guardians answered questions regarding their demographics and socioeconomic status. Associations were analyzed using multilevel Poisson regression models. Children from racial/ethnic minority groups had poorer OHRQoL. The mean CPQ11-14 score was 1.08 times higher for non-white children than their white counterparts' score. "Social" and "Emotional well-being" were the most affected domains for non-white children, with significantly higher mean scores as compared to white children (RR 1.19, 95% CI, 1.07-1.33; and RR 1.14; 95% CI 1.04-1.24). This association remained significant even after adjusting for individual and contextual covariates. OHRQoL disparities are prevalent among children from racial/ethnic minority groups. Non-white children have lower OHRQoL compared to white children.

Impact of caries prevalence on oral health-related quality of life among police personnel in Virajpet, South India.

Objective:The objective of this study is to assess the impact of caries prevalence on oral health-related quality of life among police personnel in Virajpet, South India.Materials and Methods:Police personnel were randomly selected from the 296 police staff working in Virajpet, India. They were invited for a dental examination and a questionnaire survey. A self-administered questionnaire was used to collect their demographic information, and to determine the oral health-related quality of life (OHRQoL). Caries experiences of the participants were recorded as per the World Health Organization (WHO) criteria (1997). The analysis of variance (ANOVA) was used to compare within-group differences of the selected sociodemographic factors and the Chi-square analysis was used to explore the association between the variables.Results:All the 172 invited participants joined this study. Their mean age was 38.02 ± 9.08 years. There was no significant difference in oral health-related quality of life scores according to gender and age. The prevalence of dental caries was found to be 78% in the current study. Data analysis showed that there was no statistically significant association between the oral health-related quality of life scores and caries prevalence.Conclusion:The present study showed that there was no association between the oral health-related quality of life and caries prevalence among the police personnel in Virajpet.

The effect of mandibular 2‐implant overdentures on oral health–related quality of life: an international multicentre study

To determine the difference in oral health-related quality of life (OHRQoL) in patients who received mandibular 2-implant overdentures and conventional dentures in a pragmatic international study. In this prospective study, data were gathered from 203 edentulous patients (mean age, 68.8; SD: 10.4years) at eight centres in North America, South America and Europe. The patients were provided with new mandibular conventional dentures or implant overdentures supported by 2 implants and ball attachments and opposed by conventional dentures. At baseline and at 6months post-treatment, patients rated their oral health-related quality of life using the OHIP-20. A significantly higher proportion of the participants in the implant group in North America reported improvement in both the psychological and the handicap domains, compared to those who received conventional dentures (93% vs. 52%; P<0.05). In South America, 100% of participants who received implant overdentures reported improvement in physical pain, compared to 66% in the conventional group (P<0.05). Differences in mean change scores among those who expressed improvement were not significantly different between sites or treatments. Mandibular 2-implant overdentures are more likely than conventional dentures to improve OHRQL for edentulous patients. Cultural differences were also observed in the impact of implant overdentures on the different domains of the OHIP-20.

Degree of Dry Mouth and Factors Influencing Oral Health-related Quality of Life for Community-Dwelling Elders

This study was conducted to investigate the degree of dry mouth and oral health-related quality of life and to identify factors contributing to oral health-related quality of life for community-dwelling elders. A descriptive correlational study design was used. Participants were 156 older adults from two senior welfare centers. Data were collected on February 21, 22 and 29, 30, 2009 using structured questionnaires. Enter type multiple regression analysis was used to identify factors influencing oral health-related quality of life according to general and oral health characteristics. There were significant differences in oral health-related quality of life according to living arrangement, insurance, smoking, number of natural teeth, and denture type. The oral health-related quality of life had significant correlations with the number of chronic disease, number of medications, and dry mouth. Factors influencing oral health-related quality of life for community-dwelling older adults were dry mouth, number of chronic disease, and medical aid, which explained about 47.9% of total variance. These results indicate that in order to promote oral health-related quality of life for older adults, prevention or management of chronic diseases as well as oral health and dry mouth are needed for this population, and especially economically poor elders.

Factors associated with receipt of preventive dental treatment procedures among adult patients at a dental training school in Wisconsin, 2001–2002

Gender differences in oral health-related quality of life and the fear of dental pain in seeking and receiving preventive dental care have been recognized and documented. Preventive dental treatment procedures (PDTPs) are commonly accepted as the primary approach to prevent dental disease. We examined whether the likelihood of receiving PDTPs differed by gender in adult patients receiving dental care at a dental training institution in Milwaukee, Wisconsin. Data from the Marquette University School of Dentistry electronic patient management database for 2001 through 2002 were analyzed. Descriptive, bivariate, and multivariable analyses were performed. The preventive procedures used in the study were those coded in accordance with the American Dental Association's classification system: D1110 (adult prophylaxis: professional cleaning and polishing of the teeth), D1204 (adult topical application of fluoride), D1205 (adult topical application of fluoride plus prophylaxis), and D1330 (oral hygiene instruction). Of the 1563 consecutive patient records (888 women, 675 men) reviewed for the years 2001-2002, 794 individuals (51%), aged 18 to 60 years, were identified as having received PDTPs. At the bivariate level, a significant gender difference in the receipt of PDTPs was identified (423 women [48%] vs 371 men [55%]; P = 0.004). In the multivariable analyses, age, race/ethnicity, marital status, poverty level, and health insurance type (public, private, none) were significantly associated with the receipt of PDTPs (all, P < 0.05), but gender was not. Gender differences in receiving PDTPs were not found in this dental school patient population. Receipt of PDTPs was associated with other demographic factors such as age, race/ethnicity, marital status, income level, and health insurance.
