          This study investigated denture and patient related factors associated with oral health-related quality of life (OHRQoL) of complete denture wearers and their association with general health and happiness.


          This retrospective cohort study comprised 130 participants with complete edentulism, with maxillary and mandibular complete dentures treated at Chulalongkorn University Dental School during 2010-2017. The primary outcome was the presence of overall and domain-specific Oral Impacts on Daily Performances (OIDP). Secondary outcomes were diagnosed and perceived general health, and happiness. Denture retention and stability were classified as acceptable or unacceptable following the CU-modified Kapur criteria. Five esthetic-assessment criteria of the harmonization and proportions between facial and dental anatomical landmarks were measured from patient's photographs. Age, sex, previous complete denture experience, and denture age were recorded. The associations between each variable and oral impacts were analyzed using bivariate logistic regression, and the factors with p < 0.25 were further adjusted using multivariable analysis. Associations between oral impact scores and general health and happiness were assessed using Spearman's rank correlation.


          The most frequent oral impacts were on physical domain, while social domain was the least affected. Denture retention/stability was significantly associated with both overall and specific domains of oral impact. Happiness was found to be strongly correlated with perceived general health, but marginally with oral impact scores.


          Unacceptable complete denture retention and stability are substantial risk factors for impaired OHRQoL in complete edentulism. Maintaining optimal denture retention and stability in denture wearers is essential for good oral health and well-being with the goal of enhancing happiness.

          Oral impacts affecting daily performance in a low dental disease Thai population.

          The aim of the study was to measure incidence of oral impacts on daily performances and their related features in a low dental disease population. 501 people aged 35-44 years in 16 rural villages in Ban Phang district, Khon Kaen, Thailand, were interviewed about oral impacts on nine physical, psychological and social aspects of performance during the past 6 months, and then had an oral examination. The clinical and behavioural data showed that the sample had low caries (DMFT = 2.7) and a low utilization of dental services. 73.6% of all subjects had at least one daily performance affected by an oral impact. The highest incidence of performances affected were Eating (49.7%), Emotional stability (46.5%) and Smiling (26.1%). Eating, Emotional stability and Cleaning teeth performances had a high frequency or long duration of impacts, but a low severity. The low frequency performances; Physical activities, Major role activity and Sleeping were rated as high severity. Pain and discomfort were mainly perceived as the causes of impacts (40.1%) for almost every performance except Smiling. Toothache was the major causal oral condition (32.7%) of almost all aspects of performance. It was concluded that this low caries people have as high an incidence of oral impacts as industrialized, high dental disease populations. Frequency and severity presented the paradoxical effect on different performances and should both be taken into account for overall estimation of impacts.

              The prevalence of dental impacts on daily performances in older people in Northern Thailand.

              To assess the prevalence of oral related impacts on the quality of daily life in older Thais. A cross-sectional study on a non-random sample. Metropolitan area of Chiang Mai, Thailand Subjects: 707 older individuals living independently, aged 60 to 74 years, 549 were dentate, 158 were edentate. Clinical examination and questionnaire for the Oral Impacts on Daily Performances (OIDP) index and on dental behaviours. About one half of the older people interviewed (52.8%) had at least one OIDP oral impact. The most common performance affected was eating (47.2%). The two main symptoms that caused oral impacts in the total sample were functional limitation and pain. The majority of older people had low OIDP scores below 8.0 (76.4%). Almost one in 10 had OIDP scores above 16.0. Individuals with a high income were more likely to have lower OIDP score (p<0.001). Subjects who had attended a dentist were more likely to have no oral impacts (p=0.02). There was a significant difference between OIDP scores related to some clinical variables; dental status (p=0.002), having mobile teeth (p=0.005), periodontal attachment loss (p<0.001), missing anterior and posterior teeth (p<0.001). Oral impacts that affected quality of life of older people were relatively common but not severe. The impacts were related to some social and clinical variables.
