Self-rated oral health among elderly patients attending a university dental hospital in Thailand: a telephone-based cross-sectional survey study.

Background: Oral health perception is an influential predictor of both current and future health among the elderly. However, limited research has focused on self-rated oral health among older patients attending tertiary dental care. Therefore, this study aimed to explore the potential factors associated with self-rated oral health among elderly patients attending a university dental hospital in Thailand. Methods: This telephone-based cross-sectional study was carried out among elderly patients older than 60 years who attended at least one dental visit at the university dental hospital in 2020. Hospital numbers (HN) were used to identify eligible candidates for this study. We calculated the sample size by assuming a finite population of 70,028 elderly patients with valid telephone numbers. The minimum sample required for this study was 398 participants. Trained interviewers conducted telephone calls between July 2021 and January 2022 using the validated modified oral health questionnaire. Self-rated oral health was assessed using a conventionally used global oral health question: "How would you describe your dental health?" with three response options: good, fair, and poor. Descriptive statistics, Fisher's exact test, and binary logistic regression were performed to analyze the data. Results: A total of 836 telephone numbers were called. There were 402 (48.10%) elderly patients who agreed to and completed the telephone interview. Most of the study participants were women (61.4%) between 61-74 years of age (83.1%) with a mean age of 69.18 years. Bivariate analyses showed associations between poor self-rated oral health and lower subjective oral functions: chewing discomfort (p < 0.001) and speaking discomfort (p = 0.013). However, the multivariate regression model indicated a significant association between poor self-rated oral health and chewing discomfort (p < 0.001). Therefore, elderly patients with chewing discomfort were more likely to perceive poor oral health. Conclusions: These findings indicate that difficulty chewing could be a potential factor influencing self-rated adverse oral health among older patients attending the university dental hospital. Furthermore, our study adds that the predictive power of a single-item self-measurement supports its value as a standard measure to predict oral health risk in tertiary care institutions, as well as primary care settings and community-based survey research. Therefore, healthcare providers should routinely evaluate self-rated oral health among elderly patients to detect early signs and symptoms of oral health problems, assess the success of dental treatments, and monitor general health and well-being.

Factors Associated with Self-reported Oral Health Among Community-Dwelling Older Adults in a Rural Province of Thailand.

Background: Limited research has focused on self-reported oral health in older Thai individuals. Objective: We explored the factors associated with self-reported oral health among older adults residing in rural Thailand. Methods: This cross-sectional study included males and females aged ≥ 60 years living in Phon Thong district, Roi Et province, a rural area in northeast Thailand. This community-based study was conducted between May 2021 and December 2021. A trained interviewer administered a face-to-face interview questionnaire. Study data were analyzed using descriptive statistics, Pearson's chi-squared test, and binary logistic regression. Results: In total, 249 older individuals completed the interviews. Most study participants were aged ≥ 67 years (55.8%), with a mean age of 66.92 years. Pearson's chi-squared test showed statistically significant associations between self-reported oral health and age (P = 0.035) and chewing ability (P = 0.005). The multivariate binary logistic regression analysis revealed significant associations between self-reported poor oral health and older age (AOR = 0.290, 95% CI: 0.091-0.925) and chewing discomfort (AOR = 4.032, 95% CI:1.119-14.56). We observed no significant associations between self-reported oral health and sex, toothbrushing frequency, and speaking ability. Conclusion: Younger respondents with chewing discomfort were more likely to self-report poor oral health. In rural areas, nonprofessional health providers can use a single-item self-reported oral health question as a simple tool for evaluating oral health status in the elderly. Moreover, dental health education programs are needed to help older individuals improve their oral self-care, access dental services, and achieve appropriate oral function. Such programs are essential for promoting good oral health in this population, particularly among "younger" elders.

Association Between Oral Health Literacy and Number of Remaining Teeth Among the Thai Elderly: A Cross-Sectional Study.

PURPOSE: Limited oral health literacy is associated with poor oral health status. This study aimed to determine the association between oral health literacy (OHL) and the number of remaining teeth (NRT) among Thailand's older population. PATIENTS AND METHODS: This cross-sectional study was conducted between July 1, 2020 and September 30, 2020 at the Subdistrict Health Promoting Hospitals in Panare, Pattani, Thailand. A total of 361 independent-living older adults, male and female, participated in the study. OHL data were obtained using the Thai version of Health Literacy in Dentistry (HeLD-Th) questionnaire. Trained interviewers performed face-to-face interviews for oral health-related behavior information. The NRT was collected through intraoral examination by a trained examiner. Data were analyzed using SPSS version 22. Mann-Whitney U-tests, chi-square tests, and binary logistic regression analysis were performed. A multivariate logistic regression model was developed to test associations between OHL and NRT and other potential covariates. All analyses were two-sided with a 95% confidence interval. RESULTS: There were significant associations between limited OHL and fewer than 20 remaining teeth (odds ratio [OR]=1.986, P = 0.018), older age (OR=1.743, P = 0.023), and lower educational levels (OR=2.365, P = 0.007). CONCLUSION: The significance of this evidence is that OHL influences NRT among older Thai people who have lower education levels. Therefore, OHL intervention is an essential strategy for better oral health-related behaviors to reduce tooth loss and to improve the oral health status of Thai older adults.

Effectiveness of an individually tailored oral hygiene intervention in improving gingival health among community-dwelling adults with physical disabilities in Thailand.

AIMS: Persons with physical disabilities require specific methods for sustaining good oral health. This study aimed to evaluate an individually tailored oral hygiene intervention program (IT-OHI) for improving gingival health among adults with disabilities. METHODS AND RESULTS: A single group, quasi-experimental design with pre- and post-tests, conducted at a community club for disabled people in Thailand. This study included 145 adults with disabilities, aged 18-74 years. Trained caregivers provided IT-OHI program to all participants. Calibrated dentists assessed the gingival bleeding and dental plaque at baseline/pre-intervention (T0) and at 6 (T1) and 12 (T2) weeks post-intervention. The outcomes were analyzed using the Friedman test, Cochran's Q test, and Binary logistic regression. There were significant decreases in bleeding on probing scores (P < .001) and plaque control record scores (P < .001) throughout the study. However, considering the individual periods, values between T1 and T2 did not improve. Additionally, the IT-OHI program's protective effect was more substantial among the male participants at 12 weeks post-intervention (odds ratio = 0.094, P = .027) than among the females. CONCLUSION: The IT-OHI program had partial effectiveness in improving gingival health and reducing dental plaque accumulation in a group of Thai people with physical disabilities; however, the long-term impact remains unclear.

Validation of Thai version of the Health Literacy in Dentistry scale: Validation among Thai adults with physical disabilities.

AIM: To validate the Thai version of the Health Literacy in Dentistry scale (HeLD-Th) among Thai adults with physical disabilities. METHODS: The original Health Literacy in Dentistry (HeLD) was translated into Thai (HeLD-Th). The final version of the HeLD-Th was evaluated through a cross-sectional study of 160 participants in Thailand. Interview questionnaires and oral examination were performed. The reliability and validity of the HeLD-Th were determined. RESULTS: The internal consistency was acceptable, with an overall Cronbach's alpha of 0.76. The face and content validity were confirmed. Sufficient construct validity was revealed by exploratory factor analysis. The convergent validity (P ≤ .013) and discriminant validity (P = .017) were estimated. The concurrent validity and predictive validity were confirmed by significantly higher HeLD-Th scores (P < .001). Multiple linear regression analyses indicated that approximately 60% of the variation in the HeLD-Th scores was explained by the final model. CONCLUSION: The HeLD-Th has sufficient psychometric properties to assess the oral health literacy of Thai adults with mild to moderate disabilities. There are some limitations of the study due to the small sample size, and the results are specific to Thai adults with disabilities. Future studies using the HeLD-Th scale are recommended.

Perspectives and experiences of Thai adults using wheelchairs regarding barriers of access to dental services: a mixed methods study.

PURPOSE: To explore the perspectives and experiences of Thai wheelchair users regarding barriers of access to dental services and report potential solutions in terms of customer satisfaction. PARTICIPANTS AND METHODS: We conducted a 2-phase cross-sectional study with quantitative and qualitative components at a community club for individuals with disabilities in Pathum Thani province, Thailand, in February 2018. In quantitative phase, participants were interviewed using a structured questionnaire that consisted of 1) questions on demographic characteristics and 2) adapted questions that were based on the modified Penchansky and Thomas dimensions of access. Enter method of binary logistic regression analysis was used. Regarding qualitative phase, focus group discussions were conducted using the themes of a semi-structured discussion guide. Thematic analysis was used. RESULTS: A total of 156 wheelchair users participated in the quantitative phase. Most study participants had not attended dental care services in the previous year (78.2%). Multivariate analysis found a statistically significant association that indicated that participants who had education level ≤primary education were 3.5 times more likely to had not attended a dental appointment in the previous year (P=0.003). In the qualitative phase, 33 participants were included in 3 focus groups (each comprising 11 participants), they were wheelchair users with education >primary, who did not go to see a dentist in the previous 12 months. Findings of the 3 focus groups suggest generally negative views about Thai dental services for all dimensions of access. CONCLUSION: This study reflects the unheard voices of wheelchair users and provides rigorous evidence in Thai context that difficulties of access to dental services persist. Policy makers and oral health professionals in oral health system should be alerted to the explicit barriers reported, such that equitable and equal dental services for disabled individuals can be developed.
