Oral Health Impact Profile Research Articles

Oral health and self-perceived job readiness among socially disadvantaged and unemployed citizens.

The aims of this article are (1) to evaluate the association between oral health-related quality of life (OHRQoL) and self-perceived job readiness and (2) to investigate changes in self-perceived job readiness following an oral health promotion intervention. The first aim was elucidated in a cross-sectional design, and the second through a prospective intervention study. A survey was administered among 273 unemployed vulnerable people in Copenhagen, Denmark. Participants were randomised to either control or intervention in 2018, and follow-up was conducted 7-15 months later. The intervention entailed support for dental care. OHRQoL was measured by the Oral Health Impact Profile (OHIP-14), and self-perceived job readiness was measured using the Employability Indicator Project (BIP) questionnaire. The sample reported a high mean OHIP-14 score at baseline (26.9, SD 15.6) and poor OHRQoL was significantly associated with low self-perceived job readiness (rs = -0.15, p = 0.02). The control group reported better job readiness at follow-up compared to the intervention group. However, the effect sizes were small in both groups and no clear pattern was observed. The results indicate that OHRQoL is linked to self-perceived job readiness. However, the oral health promotion applied in this study did not lead to better self-perceived job readiness. Further research is needed on the effect of oral health promotion interventions on job readiness within socially vulnerable groups.

A comparison of oral health-related quality of life and satisfaction among patients undergoing root canal treatment or tooth extraction – A prospective controlled cohort study

Objective: This study aimed to evaluate the impact of root canal treatment on Oral Health-Related Quality of Life (OHRQoL) in general dental practice and compare it with tooth extraction. Additionally, patient satisfaction following tooth-preserving treatment was assessed. Material and methods: In all, 65 patients were recruited from 6 general dental clinics in Västra Götaland over 8 weeks, with 37 starting root canal treatment and 28 having extractions. Questionnaires, including Oral Health Impact Profile-14 (OHIP-14) and 9 questions assessing patient satisfaction, were administered at treatment initiation, and at 1, 6, and 12 months. The responses from both modalities were analysed using descriptive and analytical statistical methods. Results: The response rate ranged from 73.8% to 92.3%. Regarding OHRQoL, differences between the groups were few compared to baseline. However, significant improvements were observed in the extraction group at the 6- and 12-month follow-ups, in the ‘total score’, and the dimensions ‘pain’, ‘discomfort’, and ‘handicap’. Patient satisfaction was generally high, with cost being the least satisfactory item. Pain intensity remained consistently low. Conclusions: In this prospective cohort study few differences were found between the two treatment modalities. However, significant improvements were observed in the extraction group in several dimensions. The patient satisfaction regarding root canal treatment was considered high.

A retrospective study on patient satisfaction and Oral Health-Related Quality of Life with fixed 4- or 6-implant supported prostheses over 3-7 years.

To compare patients' satisfaction and oral health-related quality of life (OHRQoL) in edentulous patients treated by All-on-4 and All-on-6 implant-supported fixed prostheses rehabilitation over 3-7 years. All patients (n = 125) were divided into short-term (3-5 years, n = 71) and long-term (5-7 years, n = 54) follow-up groups. Patients' satisfaction was examined in a cross-sectional survey. OHRQoL and psychological impact were evaluated using the Oral Health Impact Profile (OHIP). Comparison of All-on-4 and All-on-6, including OHIP values, satisfaction scores, treatment duration and complications, were analyzed using the Chi-square test and the Mann-Whitney U test. Potential influence of patient-related factors on patient-reported outcome measures (PROMs) were analyzed via the Mann-Whitney U test, the Kruskal-Wallis test and multiple regression analyses. Power calculation was conducted in R Studio. Both All-on-4 and All-on-6 follow-up groups showed high scores in total satisfaction and PROMs, including chewing comfort, aesthetics, cleanability, and stability, with no significant difference (p > 0.05). Meanwhile, no significant differences were observed in the OHIP scores between two groups in both follow-up durations (p > 0.05). However, in patients with 3-5 years follow-up, All-on-4 group had significantly lower phonetic satisfaction scores than All-on-6 group (p < 0.05). Additionally, during both follow-up periods, All-on-4 patients exhibited notably superior psychological effect in contrast to All-on-6 patients (p < 0.05). Edentulous patients treated by four or six implant-supported fixed prostheses showed same high satisfaction in oral health-related quality of life in both 3-5 years and 5-7 years follow-ups.

An investigation of machine learning algorithms for prediction of temporomandibular disorders by using clinical parameters.

This study aimed to predict temporomandibular disorder (TMD) using machine learning (ML) approaches based on measurement parameters that are practically acquired in clinical settings. 125 patients with TMD and 103 individuals without TMD were included in the study. Pain intensity (with visual analog scale), maximum mouth opening (MMO) and lateral excursion movements (with millimeter ruler), cervical range of motion (with goniometer), pressure pain threshold (PPT; with algometer), oral parafunctional behaviors (with Oral Behaviors Checklist), psychological status (with Hospital Anxiety and Depression Scale), and quality of life (with Oral Health Impact Profile) were evaluated. The measurements were analyzed via over 20 ML algorithms, taking into account an extensive parameter tuning and cross-validation process. Results of variable importance were also provided. Bagging algorithm using Multivariate Adaptive Regression Spline (MARS) algorithm (accuracy = 0.8966, area under receiver operating characteristic curve = 0.9387, F1-score = 0.9032) was the best performing model regarding the performance criteria. According to this model, the 5 most important variables for predicting TMD were pain intensity, MMO, lateral excursion and PPT values of masseter and temporalis anterior muscles, respectively. The Bagging algorithm using the MARS algorithm is a robust model that, in combination with clinical parameters, assists in the detection of patients with TMD in settings with limited capabilities. The clinical parameters and ML algorithm proposed in this study may assist clinicians inexperienced in TMD to make a preliminary detection of TMD in clinics where diagnostic imaging tools are limited.

Effect of Electrical Stimulation of Lingual Nerve on Xerostomia: A Randomized Controlled Trial.

Xerostomia is a subjective sensation of dry mouth affecting millions of people worldwide. Current management has limitations, often causing side effects. This study aims to investigate whether electrical stimulation of the lingual nerve could offer effective relief for xerostomia sufferers. Eligible participants were randomly assigned (1:1) to either the experimental or sham group, receiving electrical stimulation of the lingual nerve (n = 24) or sham stimulation (n = 23) for 12 wk. The primary outcome is the changes in xerostomia score using a 100-mm visual analog scale throughout the therapy. Participants assessed their dryness and assigned corresponding scores, with lower scores indicating more severe dry mouth. Secondary outcomes included remission rate in dry mouth frequency, changes in stimulated/unstimulated salivary flow rate (SSFR/USFR), and changes in Oral Health Impact Profile-14 (OHIP-14) questionnaire scores, where higher scores indicate greater impact on oral quality of life. At week 12, the electrical stimulation group showed greater improvement in xerostomia score compared to the sham group, with a mean between-group difference of 13.8 (95% confidence interval [CI], 10.0-17.6). The therapeutic effect of electrical stimulation was also confirmed by secondary outcomes. The remission rate of dry mouth was higher at 12 wk in the electrical stimulation group (61.9% [95% CI, 40.9%-79.3%] vs. 28.6% [95% CI, 13.8%-50.0%]). Participants in the electrical stimulation group also experienced a greater increase in USFR, with a mean difference of 14.5 (6.1-23.0) μL/min. Moreover, they exhibited significant improvement in OHIP-14 score after 12 wk of therapy, with a mean between-group difference of -10.0 (-13.9 to -6.2). No significant difference was observed between the 2 groups for SSFR (P = 0.702). Electric stimulation offers promise as a noninvasive, nonpharmacological strategy for the management of xerostomia. Further research is needed to understand its long-term effectiveness, optimal parameters, and underlying mechanisms. The study confirmed that electrical stimulation of the lingual nerve is a promising noninvasive and nonpharmacological modality for relief of xerostomia.

Tongue and Lip Strength and Endurance in Healthy Young Adults With and Without Orofacial MyofunctionalDisorders.

Based on the premise that tongue and lip force is affected in individuals with orofacial myofunctional disorders (OMDs), orofacial myofunctional therapy (OMT) programs typically include the strengthening of orofacial muscles through isometric and isotonic exercises. The purpose of this study is to examine whether there is indeed a measurable difference in maximum tongue and lip strength and endurance between subjects with and without OMDs, as well as to explore Oral Health-Related Quality of Life (OHRQoL) in this population. Sixty healthy young adults (mean age 18.9 years, SD 0.69 years, range 18.0-21.4 years) participated in this study. Perceptual evaluation of orofacial functions was conducted using the Orofacial Myofunctional Evaluation with Scores (OMES) protocol. Participants were divided into three groups, namely those with physiological orofacial functions (POF; n = 20), those with inconsistent orofacial functions (IOF; n = 11), and those with consistent OMDs (OMD; n = 29). Maximum isometric pressure and endurance of tongue and lips were measured using the Iowa Oral Performance Instrument (IOPI). OHRQoL was assessed using the Oral Health Impact Profile (OHIP-14). The OMES total scores did not differ significantly between the three groups, though the subscale 'function' showed significant differences (13.637; p = 0.001). No statistically significant differences in maximum isometric pressure or endurance for tongue and lips, nor for OHIP scores, were measured between the three groups. Although orofacial muscle strengthening is commonly part of OMT, current findings suggest the superfluity of these types of exercises in the treatment of OMDs in healthy young adults and may indicate the need to focus on awareness and rehabilitation of pathological functions in these individuals. Re-evaluation of the efficacy of OMT programs in different populations may be an important strategy going forward.

The influence of dental bleaching on patient's quality of life: A multistudy analysis of aesthetic and psychosocial outcomes

ObjectivesTo assess the Quality of Life (QoL) of participants treated with dental bleaching using different techniques by administering two questionnaires Oral Health Impact Profile (OHIP-14) and Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ), as well as the bleaching efficacy and tooth sensitivity (TS). Materials and MethodsSecondary results for nine randomized clinical trials were included, involving 489 participants who underwent bleaching procedures. The questionnaires were applied at baseline and 30-day post-bleaching. Bleaching efficacy (ΔSGU/ΔEab) and TS were also evaluated (VAS/NRS). The effect of bleaching on aesthetic self-perception was evaluated using the Paired t-test. The Kruskal-Wallis test assessed variations by technique. Also, the correlations between questionnaires and outcomes was evaluated (α = 0.05). ResultsAfter the bleaching treatment, both questionnaire revealed significant differences compared to the baseline, regardless of the factor evaluated (p < 0.05), except for Physical pain in OHIP-14 (p = 0.53). No correlation was found between OHIP-14 and bleaching efficacy (p < 0.008). A significant correlation was found between bleaching efficacy and dental self-confidence, indicating that dental self-confidence increased as the number of SGU (ΔSGU) increased, while social impact (ΔEab) and aesthetic concern (ΔSGU) decreased. Additionally, a significant correlation was observed between TS and OHIP-14 (Physical pain). For PIDAC, both dental self-confidence and psychological impact were correlated with TS in the VAS. ConclusionSubjects who underwent dental bleaching treatment improved their self-perception and dental self-confidence. Dental bleaching, besides enhancing the patient's smile, also improves their self-esteem. Clinical RelevanceDental bleaching, besides improving the patient's smile, also enhances their self-esteem.

Unequal smiles: consequences of untreated dental caries in citizens living in vulnerable circumstances in the Netherlands: an exploratory pilot study.

The often poor oral health status of socioeconomically vulnerable adults is widely recognised. Nevertheless, research on it is scarce. To address this gap, this exploratory pilot study aimed to report on the prevalence of untreated caries and its clinical odontogenic consequences, as well as the associated Oral Health Related Quality of Life (OHRQoL) in a marginalised adult Dutch population. The Dutch department of Médecins du Monde (Doctors of the World) included socioeconomically vulnerable (low socioeconomic position [SEP]) adults in the Netherlands through community organisations. The validated Deprivation in Primary Care Questionnaire (DiPCare-Q) was translated in Dutch and used to characterise the SEP of the population. To document untreated caries and severe odontogenic consequences, the DMFT (Decayed, Missing, Filled Permanent Teeth) and PUFA (Pulpal, Fistula, Ulceration, Abscess) index were used. The validated Dutch Oral Health Impact Profile questionnaire (OHIP-14) was used to document the impact of these issues on OHRQoL. Data analysis was conducted in SPSS® (Statistical Package for the Social Sciences) statistics (Kruskal-Wallis, Mann-Whitney-U-test) and STATA software. Data from 59 adult participants were analysed. The prevalence of untreated caries (DT ≥ 1) was 65.5%, 57.9% of which experienced severe odontogenic consequences (DT+PUFA). The prevalence of severe odontogenic consequences (PUFA ≥ 1) was 45.5%. The mean OHIP-14 score of 17.7 ± 13.4 (25th-75th percentile: 6-26) illustrated that untreated caries may have impact on OHRQoL. Individuals who experienced any severe odontogenic consequences from untreated caries reported significantly higher OHIP-14 scores (mean ± s.d.: 21.8 ± 14.8 vs.11.1 ± 7.2). The untreated caries and severe odontogenic consequences seen in a large number of the socioeconomically vulnerable adult participants seemed to have an impact on OHRQoL. These findings emphasise the urgency of including these adults in the professional oral health system for treatment and prevention, and may emphasise the necessity of improving the socioeconomic circumstances of this population. Further exploration of the exact barriers and facilitators to oral healthcare access for socioeconomically vulnerable adults is necessary.

Oral health-related quality of life among oropharyngeal cancer survivors

ObjectivesThe incidence of oropharyngeal cancer continues to rise in the United States, yet studies on the quality of life (QoL) of oropharyngeal cancer patients are limited. The objective of this pilot study was to assess the impact of oral health on the QoL in oropharyngeal cancer survivors. Materials and MethodsOropharyngeal cancer survivors with a confirmed cancer diagnosis from 1996 to 2016 were sampled from the Utah Cancer Registry. The Oral Health Impact Profile-14 (OHIP-14) questionnaire was administrated between January and May of 2019. The impact of oral health on QoL was evaluated using simple linear regression (β-coefficient). ResultsAmong the 260 oropharyngeal cancer survivors, the majority were male (84.6 %) and ≥ 60 years of age at the time of cancer diagnosis (74.0 %). The most frequently reported symptoms of OHIP-14 were discomfort while eating any foods (19.2 %) and worsening sense of taste (16.0 %). The overall OHIP-14 mean score was 13.3. Significantly worse OHIP-14 scores were observed for females (β = 12.85, p = 0.01), chemotherapy recipients (β = 6.60, p = 0.02), and past smokers (β = 5.25, p = 0.04). Better OHIP-14 scores (better oral QoL) were observed in patients with distant cancer stage (β = −7.66, p = 0.01), higher income (β = −2.50, p = 0.05), and older age at cancer diagnosis (β = −0.35, p = 0.03). ConclusionThe oral health-related quality of life scores observed in this pilot study suggest a need for improvement in patient symptom management over time.

Impact of malocclusion and oral habits on oral health-related quality of life and sleep disturbance in young adults : Across-sectional study.

The aim of this study was to investigate the impact of malocclusion and oral habits on oral health-related quality of life and sleep disturbance in young adults. Across-sectional study was conducted with asample of 213 young adults aged 18-30years. Dental occlusion data were assessed through clinical examination. Aquestionnaire was used to collect data on oral habits. Outcomes were collected using the Oral Health Impact Profile (OHIP-14) and Mini Sleep Questionnaire. Anterior open bite (adjusted odds ratio [OR] = 2.41, 95% confidence interval [CI] = 1.02-5.67, p = 0.044), swallowing disorders (adjusted OR = 2.39, 95% CI = 1.13-5.05, p = 0.022), and sleeping on hands were associated with anegative impact on oral health-related quality of life. Females (adjusted OR = 2.61, 95% CI = 1.10-6.17, p = 0.029), teeth grinding (adjusted OR = 2.78, 95% CI = 1.08-7.14, p = 0.034), biting lips or cheeks (adjusted OR = 4.28, 95% CI = 1.49-12.29, p = 0.007), and self-perception of need for orthodontic treatment (adjusted OR = 7.88, 95% CI = 2.12-29.30, p = 0.002) were associated as arisk for sleep disturbances. The findings suggest that oral habits and some types of malocclusions can impact oral health-related quality of life. In addition, sleep disturbances were associated with agreater need for orthodontic treatment and ahabit of grinding teeth in young adults.

Fully digital versus conventional workflow: Are removable complete overdentures equally good? A randomized crossover trial.

Implant-supported removable complete overdentures (IODs) are a common treatment in case of edentulism and malfunctioning of the conventional denture. Manufacturing IODs in a conventional way (C-IODs) is time-consuming, but in a digital workflow, this can be done in three sessions. Digitally produced IODs (3D-IODs) are also more advantageous than C-IODs because lost or broken 3D-IODs can be swiftly reproduced as the digital design is always available. To prove in a non-inferiority study, with a margin of 0.3 point per Oral Health Impact Profile-20 (OHIP-20) question, that IODs made according to a fully digital workflow (3D-IODs), function as good as C-IODs with respect to patient-reported outcome measures (PROMs). This randomized crossover study included 36 fully edentulous patients who showed extreme resorption of the maxillary alveolar process, making denture retention difficult. After a maxillary bone augmentation and the installation of 4-6 implants, each patient wore both types of IOD for 1 year each, with the order reversed in two subsets of patients. The 3D-IODs and C-IODs were fabricated in advance for both jaws (at least two mandibular implants were already present). The OHIP-20 survey was performed at baseline, after 1 year (before the IOD switch), and after 2 years to determine patient satisfaction scores using a visual analog scale (VAS). The general health status was assessed using the Short Form (SF-36) questionnaire. Regarding the PROMs, patients preferred the 3D-IOD: the improvement on the overall OHIP scale (0-4), expressed as a mean, was 0.26 points greater than for the C-IOD (p < 0.001). This applied also to the VAS scale (1-100) with an increase of 7.37 points (p < 0.001). Regarding the SF-36 scale, only for the item "emotional well-being," the 3D-IOD scored significantly better (p = 0.033). Compared with conventionally fabricated C-IODs, fully digitally produced 3D-IODs resulted in significantly higher OHIP-20 and satisfaction scores.

EVALUATION OF ORTHODONTIC TREATMENT NEED AND ITS ASSOCIATION WITH SELF-ESTEEM AND ORAL HEALTH-RELATED QUALITY OF LIFE OF PATIENTS RECEIVING CARE AT SAIDU COLLEGE OF DENTISTRY, SWAT

Orthodontic treatment needs can impact both self-esteem and oral health-related quality of life (OHRQoL). The relationship between these factors, particularly in a developing region, remains underexplored. Objective: To investigate the relationship between orthodontic treatment needs, self-esteem and oral health-related quality of life among patients at Saidu College of Dentistry, Swat. Methods: This cross-sectional study was conducted at Saidu College of Dentistry, Swat and included 115 participants aged 8-30 years. Data were collected using the Index of Orthodontic Treatment Needs (IOTN), Rosenberg Self-esteem Scale and Oral Health Impact Profile (OHIP-14) over a six-month period. Demographic variables such as age, gender and socioeconomic status were also analyzed. Descriptive statistics and statistical tests such as chi-square and t-tests were employed to evaluate associations between variables, with significance set at p &lt; 0.05. Results: Of the 115 participants, 59.1% were male and 40.9% were female. Age groups were distributed as 33% (8-15 years), 39.1% (15-22 years) and 27.8% (22-30 years). Socioeconomic analysis revealed that 25.2% belonged to the upper class, 49.6% to the middle class and 25.2% to the poor class. Severe orthodontic treatment needs were identified in 36.5% of participants. Self-esteem scores were unaffected by gender, age, or socioeconomic status. In contrast, oral health impact scores were notably high, with a mean OHIP-14 score of 19.77±17.7, indicating a significant need for comprehensive oral health care. Conclusion: Despite high orthodontic treatment needs, participants exhibited stable self-esteem levels, suggesting resilience in psychosocial health. The findings emphasize the strong connection between orthodontic needs, OHRQoL and patient demographics, providing important insights for oral health professionals in addressing both clinical and psychological aspects of care.

Influence of age and gender on oral health impact profile among dental implant patients in alkarkh district in Baghdad / Iraq: cross-sectional study.

To evaluate the age and gender influence on the quality of life of patients with a dental implant. The cross-sectional study was conducted from February to April 2022 at Al-Mammon Specialised Dental Centre in the Al-Karkh sector of Baghdad, Iraq, and comprised healthy adult subjects of either gender who had dental implant treatment in the preceding 2 years and their dental implant was in place for at least 6 months. . Data was collected using the Oral Health Impact Profile Questionnaire to measure oral health quality of life. Data was analysed using SPSS 22. Of the 103 subjects, 55(53.4%) were females and 48(46.6%) were males. There were 41(39.81%) subjects aged 18-37 years, 42(40.78%) aged 37-56 years and 20(19.42%) aged 57-74 years. Of the total, 50(48.5%) subjects had moderate health quality, followed by 26(25.24%) low and 27(26.21%) high. There was a significant association of age and gender on the quality of life (p<0.05). Age and gender were found to be important factors influencing the quality of life of dental implant patients.

Psychological problems and their impact on oral mucosal disease patients’ quality of life: A cross-sectional study in the Chinese population

ObjectivesWe aimed to investigate the presence of common psychological factors (i.e., stress, depression, anxiety) and their impact on the Oral health-related quality of life (OHRQoL) in patients diagnosed with four oral mucosal diseases (OMDs): recurrent aphthous ulcers (RAU), oral lichen planus (OLP), oral leukoplakia (OLK), and oral submucous fibrosis (OSF). MethodsA total of 229 patients with clinically diagnosed OMDs were enrolled in this study, consisting of 55 RAU, 68 OLK, 50 OLP, and 56 OSF patients. The patients were statistically analyzed for psychological problems and OHRQoL using the Visual Analog Scale (VAS)､ the 5-item Oral Health Impact Profile (OHIP-5) and the Depression Anxiety Stress Scale-21 (DASS-21) scales. ResultsThere were 229 valid questionnaires collected, consisting of 83 females and 146 males with a mean age of 45.24 (SD = 11.88) years. Multiple regressions between DASS-21 scores and OHIP-5 scores revealed generally negative impacts of psychological problems on OHRQoL, with depression on OLP (β = 0.47), OLK (β = 0.65) and OSF (β = 0.38), stress on RAU (β = 0.29), OLP (β = 0.72), OLK (β = 0.38) and OSF (β = 0.60), and anxiety on OLP (β = 0.33), OLK (β = 0.49) and OSF (β = 0.51). ConclusionsPsychological problems like depression, stress, and anxiety were found to be prevalent in OMDs patients and adversely affected their OHRQoL. The results support the biopsychosocial medical model in the treatment of OMDs patients. Clinical significanceThe present study reinforced the crucial roles of psychological factors in impacting OMDs patients' OHRQoL. Therefore, it is necessary to monitor patients’ psychological status and OHRQoL using questionnaires like DASS-21 and OHIP-5. Followed by psychological interventions, the treatment is expected to be enhanced.

Efficacy of different low-level laser therapy sessions in the management of masseter muscle trigger points

BackgroundLow-level laser therapy (LLLT) is one of the recent treatment modalities for myofascial pain dysfunction syndrome with trigger points. The objective of the present study was to examine the impact of varying LLLT sessions on the treatment of masseter muscle trigger points.Methods90 patients diagnosed with orofacial pain and trigger points in the masseter muscle for at least 6 months were selected and divided into 3 groups (n = 30) based on the number of LLLT sessions provided to patients. Patients in Group I received one session/per week, group II received two sessions/per week, and Group III received three sessions/per week. The sessions continued for 4 weeks, evaluations of pain levels, maximum mouth opening (MMO), and quality of life were conducted before and after the procedure at 1, 2, 3, 4, and 8 weeks.ResultsThe pain scores exhibited a highly statistically significant difference among the three groups (p < 0.001) over the 8-week study period. MMO was statistically significantly different between groups at week 4 and week 8. The Oral Health Impact Profile-14 (OHIP-14) score was statistically significant difference between groups at week 8. The time showed a highly significant effect on the study outcomes within each group.ConclusionIncreased the number of LLLT sessions reduced the pain improved the MMO, and subsequently improved the quality of life.ClinicalTrials.gov IDNCT06327204 - retrospectively registered.

Stress is simultaneously related to sleep and temporomandibular disorders.

This study aimed to clarify the relationship between the oral environment and psychological factors as predictor variables of sleep quality, in addition to inferring the relevant mechanisms of sleep and temporomandibular disorders (TMDs) by analyzing the relationship between TMDs and stress. This cross-sectional study analyzed data from 1,032 participants, comprising 420 men and 612 women, from the 2017 Iwaki Health Promotion Project using multiple regression analysis. The primary endpoints were the scores of each item in the Pittsburgh Sleep Quality Index (PSQI) and its sum. Predictor variables included the number of teeth; TMDs; stress, assessed using the World Health Organization-5 (WHO-5); sleep bruxism; and oral health-related quality of life, assessed using the oral health impact profile-14 (OHIP14). The confounding factors included age, body mass index, and alcohol intake. Multiple regression analysis revealed that TMDs (β value = 0.293, p = 0.034) and stress (β value = 1.3, p < 0.001) were significantly correlated with the PSQI total score. In addition, TMDs were significantly correlated with stress (β value = 0.076, p = 0.007). The significant relationship between sleep and TMDs suggests that mental stress contributes to the development sleep disorders and consequently is associated with the development of TMD symptoms.

Relationships Between Test Results for Oral Hypofunction, Subjective Frailty Symptoms and Oral Health-Related Quality of Life of Japanese Dental Outpatients: A Multicentre, Cross-Sectional Study.

Oral hypofunction is the stage before oral dysfunction. The subjective symptoms of poor oral function and the decline in oral health-related quality of life (OHRQoL) that occur in the oral hypofunction stage can be missed. This multicentre cross-sectional study was performed to examine the relationships between the test results for oral hypofunction, subjective frailty symptoms and OHRQoL of outpatients in dental clinics. The basic characteristics and oral function test results of 637 dental clinic outpatients were evaluated. The subjective symptoms of physical and oral frailty were investigated using a questionnaire. OHRQoL was assessed using the Japanese short version of the Oral Health Impact Profile (OHIP-JP16) and OHRQoL dimension score. The overall prevalence of oral hypofunction was 37.8%, with no significant difference between men and women. No significant differences in the presence or absence of subjective symptoms of frailty and a high OHIP score were observed based on sex. However, the prevalence of oral hypofunction was significantly different among the age groups and increased with age. The subjective symptoms of frailty score, OHIP score and OHRQoL dimension score were significantly higher in patients with versus without oral hypofunction. Age, number of underlying diseases, total score for subjective symptoms of frailty, total score for OHIP and OHRQoL dimension score were significantly associated with oral hypofunction. Oral hypofunction may affect the subjective symptoms of frailty and OHRQoL in older adults.

Pain, Function and Quality of Life in Temporomandibular Disorder Patients With Different Disc Positions.

Whether pain, jaw function and quality of life are correlated with disc positions is controversial, and similar studies evaluating disc positions by magnetic resonance imaging (MRI) are very limited. This study evaluated the pain, mandibular function and quality of life of the temporomandibular disorders (TMDs) patients with different disc positions according to MRI, and the relationship among them. Three hundred and thirty-five participants were included. Patients completed questionnaires included the Numeric Rating Scale (NRS), Jaw Functional Limitation Scale 8-item (JFLS-8), the Generalised Anxiety Disorder 7-item (GAD-7), Patient Health Questionnaire 9-item (PHQ-9) and Oral Health Impact Profile for TMD (OHIP-TMD). MRI was conducted to evaluate these diagnoses, resulting in the identification of three distinct categories: normal positioning (NP), disc displacement with reduction (DDwR) and disc displacement without reduction (DDwoR). Participants had the mean age of 28.55 ± 11.10 years (80.90% women). DDwR and DDwoR had a higher percentage of females compared with NP. Significant differences existed among patients in all questionnaires. The DDwoR group had significantly the highest pain, functional limitation and the worst quality of life. Moreover, they experienced the most difficulties in chewing tough foods, yawning, experiencing pain and psychological discomfort. Moreover, the multivariate regression showed that age, female gender, diagnosis as DDwoR, GAD-7 and PHQ-9 were significantly linked to higher functional limitation. Worse quality of life was associated with age, diagnosis as DDwoR, GAD-7 and PHQ-9. Among patients with different disc positions, DDwoR showed the highest pain, functional limitation and the worst quality of life. Also, NP showed a proportion of chronic pain. Physical pain, psychological discomfort and chewing tough food were regarded as the most impaired. Women who experience anxiety and depression tended to have a higher propotion of dysfunction and a lower quality of life.

Reliability and validity of a Hindi version of the Oral Health Impact Profile (OHIP-EDENT-H) for edentulous subjects: A Cross-Sectional study

AimThe study aimed to translate the OHIP-EDENT into Hindi and assess its validity and reliability. MethodsThe study included 150 participants whose demographic information was collected using the Modified Kuppuswamy Socio-economic Scale. The Oral Health Impact Profile in Edentulous (OHIP-EDENT) was translated into Hindi using the standard forward-backward method. Test-retest reliability was assessed using the Intra-class Correlation Coefficient (ICC) and internal consistency using Cronbach's alpha. The Kaiser-Meyer-Olkin (KMO) test and Bartlett's test of sphericity coefficient were used to conduct Exploratory Factor Analysis (EFA) and confirm the Construct validity. To establish Convergent validity, the relationship between the global question and the OHIP-EDENT-H subscale scores was observed. ResultsThe data was analyzed with a confidence level of 95 %, and statistical significance was interpreted as a p-value of less than 0.05. The Cronbach's alpha score for OHIP-EDENT-H was 1.00, indicating high internal consistency. The corrected item-total correlations ranged from 0.665 to 0.923, and the total ICC score was 0.763, demonstrating good reliability. The subscales' intra-class correlation coefficient values ranged from 0.968 to 0.997, indicating high reliability. However, items 4, 6, 13, 17, 18, and 19 had factor loadings below the acceptable threshold of 0.40 in the factor analysis. Additionally, the total and subscale scores of the OHIP-EDENT-H showed significant correlations with global question, with correlation coefficients ranging from 0.665 to 0.923. ConclusionThe Hindi version of OHIP-EDENT is a reliable and valid tool for evaluating the OHRQoL of Hindi-speaking edentulous individuals.

Validation of the Jamaican version of the Oral Health Impact Profile (OHIP-14) in adults: JAM-OHIP study

Background: The Oral Health Impact Profile (OHIP-14) is a widely used tool for measuring the effects of oral health-related quality of life (OHRQoL). However, the validity of the OHIP-14 in the Jamaican context, referred to as the Jamaican Oral Health Impact Profile (JAM-OHIP), has yet to be established. Purpose: To determine the validity of the Jamaican language version of the OHIP in evaluating the OHRQoL of Jamaican adults. Methods: The original English version of the Oral Health Impact Profile (OHIP-14) was translated into the Jamaican language using forward and backward translation. The JAM-OHIP was used to evaluate the OHRQoL of 236 individuals at the University of the West Indies Dental Polyclinic. The overall fit was checked using a chi-square test (p &gt; 0.05), comparative fit index (CFI), Tucker–Lewis index (TLI), root mean square error of approximation (RMSEA), and standardized root mean square residual (SRMR). Results: More DMFT (p &lt; 0.01) was associated with high JAM-OHIP scores, and the most impacted domain was physical pain. Cronbach’s alpha and the standardized item alpha for the JAM-OHIP were 0.82. The overall fitting results for the CFA were χ²(68) = 80.558, p = 0.142, and χ²/g.l. = 1.185. The CFI and TLI were 0.996 and 0.994, respectively. The SRMR was 0.072 and the RMSEA was 0.028 (CI95% = [0.000; 0.050]) p = 0.953. Conclusions: The JAM-OHIP instrument was shown to be reliable and valid for the assessment of OHRQoL in the Jamaican adult population.
