Objectives : The objective of this study was to assess a level of oral health related quality of life(OHRQoL) for rural communities elderly and to determine the association between OHRQoL and socio-economic position. Methods : The study population was elderly(60+year-old) residents of PyeongChang county, Jeongseon county, Yeongwol county, Gangwon province. A total of 171 people were invited to participate. Oral health related quality of life was measured using the GOHAI. The data were analyzed with Mann-Whitney U test or Kruskal-Wallis test and to assess socio-economic inequalities in OHRQoL(GOHAI), we used multi-variable logistic regression models. We used models adjusting for age, sex, family status factors(Model I) and compared them to models additionally adjusting for stress level(Model II). Results : There were significant differences in lower score of GOHAI at lower age group and live alone group. And we found that lower SES was significantly associated with lower score of OHRQoL. Social gradient in the score of OHRQoL persisted when adjusted for age, sex, family status, stress level. Conclusions : We recommend that oral health promotion program should be developed after due consideration SES for rural communities elderly because OHRQoL of rural communities elderly was low and association between SES and OHRQoL for rural communities elderly.

Objectives: This study conducted a literature review to systematically confirm the quantitative results of individual studies on oral health-related quality of life (OHRQoL) among elderly adults. Methods: Studies on quality of life related to oral health among Korean elderly adults were selected as targets, and literature published in Korean journals until January 10, 2019, was examined. A total of 179 papers were reviewed using RISS, KISS, eArticle, and DBpia, and 17 papers meeting the final conditions were selected for analysis. Factors were categorized with publication year, sample size, gender, and statistical analysis as main variables. Relevant factors and effect sizes were then encoded, and the values of correlation coefficients and correlation effect sizes were coded. Results: After classifying the factors affecting OHRQoL among elderly adults according to common characteristics, four studies related to food and diet, five studies related to xerostomia, and four studies related to dentures and denture satisfaction were found to be related. Conclusions: Overall, various factors affected OHRQoL among elderly adults. Therefore, oral health among elderly adults must be developed and managed considering the various factors related to OHRQoL.

Background: The Child Oral Health Impact Profile (COHIP) is a measure of oral health-related quality of life (OHRQoL) in children and adolescents. This study examined the impact of dental fear on the OHRQoL by comparing the COHIP scores of children with and without dental fear. Methods: The OHRQoL in children and adolescents was measured using the Korean version of the COHIP. In total, 102 students (49 boys and 53 girls) filled in a questionnaire designed to evaluate dental fear and the OHRQoL in 2012 and 2014. Results: In 2012, the group without dental fear showed higher COHIP scores than the group with dental fear; the difference between the two groups was statistically significant. In 2014, the same pattern was observed, but the difference was non-significant for all COHIP items other than those pertaining to social-emotional well-being. Comparison of COHIP scores according to changes in fear showed that the group with continuous dental fear showed significantly lower overall COHIP, negative COHIP, and low social-emotional wellbeing scores, than the group without continuous fear in 2012 and 2014. Conclusion: We expected children with dental fear to have poor oral health, affecting their OHRQoL; however, dental fear did not affect the OHRQoL.

The purpose of this study was to analyze the relationship between objective oral health status determined by dentists, self-perceived subjective oral health status, and oral health related quality of life (OHRQoL) in the elderly. The related factors affecting OHRQoL in the elderly were also surveyed. Four hundred and thirty elderly individuals who visited the three public health centers and four dental clinics in Busan were selected by convenience sampling. Twelve dental hygienists investigated the subjective oral health status and OHRQoL using the 14-item Oral Health Impact Profile (OHIP-14) and twentyone dentists examined the objective oral health status, including healthy remaining teeth, treated remaining teeth, functional remaining teeth, missing teeth, and non-treated missing teeth. Data were analyzed using SPSS ver. 12.0. OHRQoL was higher when oral and periodontal status was perceived as healthy, when there was no toothache, no interference in mastication, and when study subjects had the ability of food softening. It was also higher when study subjects had ${\geq}20$ remaining teeth and <9 missing teeth, and were wearing denture. The related factors affecting OHRQoL of the elderly were the type of medical insurance, toothache, ability of food softening, perception of periodontal status, and the number of healthy remaining teeth. There was a significant relationship between the subjective-objective oral health status and OHRQoL in the elderly. A continuous oral health care system aimed at retaining ${\geq}20$ healthy remaining teeth is needed to improve oral health and OHRQoL for the elderly, especially for the elderly receiving medical aid.

Objective: The purpose of this study was to evaluate the effect of malocclusion or orthodontic treatment on oral health-related quality of life (OHRQoL) in adults. Methods: The sample consisted of 860 adults (378 men and 482 women, aged 18-39 years) who were clinically evaluated for malocclusion or orthodontic treatment experience. Participants were divided into 4 groups as follows: normal occlusion, malocclusion, fixed treatment, and retention. OHRQoL was assessed with the short form of the Oral Health Impact Profile (OHIP-14) and Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ). Results: The malocclusion group and the fixed treatment group had significantly higher OHIP-14 scores than the normal occlusion group and the retention group (p < 0.001). The malocclusion group had the highest PIDAQ score, while the normal occlusion group and the retention group had the lowest PIDAQ score (p < 0.001). Women had higher OHIP-14 and PIDAQ scores than men. A significant positive correlation was found between OHIP-14 and PIDAQ scores (p < 0.01). Conclusions: Malocclusion has a negative impact on OHRQoL, but this could be improved in adults through orthodontic treatment. These OHRQoL questionnaires can provide additional useful information on specific aspects of orthodontic patients' psychological state.

Objective: The aim of this randomized controlled clinical trial was to compare oral health-related quality of life (OHRQoL) of patients treated with conventional, active self-ligating (ASL), and passive self-ligating (PSL) brackets in different therapeutic phases. Methods: Sixty patients (mean age 18.3 years; 29 males and 31 females) requiring orthodontic treatment were randomly and equally assigned to receive conventional (Victory Series), ASL (In-Ovation R), or PSL (Damon 3MX) brackets. OHRQoL was measured with a self-administered modified 16-item Malaysian version of the Oral Health Impact Profile for immediate (soon after the visit) and late (just before the subsequent visit) assessments of the bonding and activation phases. Data were analyzed with the Kruskal-Wallis and chi-square tests. Results: The PSL and ASL groups showed more immediate and late impacts in the bonding phase, respectively; the conventional group was affected in both the assessments. The first activation phase had similar impacts in the groups. After the second activation, the conventional group showed more immediate impacts, whereas the PSL and ASL groups had more late impacts. The commonly affected domains were "physical disability," "functional limitation," "physical pain," and "psychological discomfort." No significant differences in the prevalence and severity of immediate and late impacts on OHRQoL of the patients were noted in any therapeutic phase. Conclusions: No bracket system seems to ensure superior OHRQoL. This information could be useful for explaining the therapeutic phases, especially the initial one, and selecting the optimal bracket system based on the patient's preference.

Purpose: Depression is a condition that weakens psychosocial functioning and reduces quality of life. In Korea, the prevalence of depression among the elderly is 29.2% and depression is a considerable public health concern for the elderly. Depression has a statistically significant relationship with oral conditions such as number of teeth and salivary flow rate. Oral health-related quality of life (OHRQoL) is the concept including subjective evaluations of psychological, physical and social aspects of oral health. Tooth loss and hyposalivation can affect mental health and quality of life. Our study was designed to identify the relationship among the number of teeth, salivation, OHRQoL, and depressive symptoms in the elderly in Korea. Methods: We recruited 100 participants, aged over 65 years, and assessed their number of teeth, unstimulated salivary flow rate. All participants filled out oral health impact profile 14 (OHIP-14) and Zung self-rating depression score (SDS) for checking OHRQoL and depressive symptoms. Statistical analysis was done by R program. Results: We found that the positive relationship between OHIP-14 and SDS after Mann-Whitney test (p=0.03). The lower SDS group had an OHIP-14 median score of 4. On the other hand, the higher SDS group had a median value of 7.5. The other factors (number of teeth and salivary flow rate) did not show correlations with OHIP-14 or SDS. Conclusions: OHRQoL and depressive symptoms have significant correlation.

We study a bivariate response regression model with arbitrary marginal distributions and joint distributions using Frank and Clayton's families of copulas. The proposed model is used for fitting dependent bivariate data with explanatory variables using the log-odd log-logistic Weibull distribution. We consider likelihood inferential procedures based on constrained parameters. For different parameter settings and sample sizes, various simulation studies are performed and compared to the performance of the bivariate odd-log-logistic-Weibull regression model. Sensitivity analysis methods (such as local and total influence) are investigated under three perturbation schemes. The methodology is illustrated in a study to assess changes on schoolchildren's oral health-related quality of life (OHRQoL) in a follow-up exam after three years and to evaluate the impact of caries incidence on the OHRQoL of adolescents.
