Determinants and inequality of recurrent aphthous stomatitis in an Indonesian population: a cross sectional study.

INTRODUCTION: Recurrent Aphthous Stomatitis (RAS) is the most common type of ulceration in the oral cavity which can occur due to several factors. AIMS: To determine the factors related to the incidence of RAS and examine the social class inequality in RAS among the Indonesian population using data from the fifth wave of the Indonesian Family Life Survey (IFLS5) in 2014. METHODS: This study is a descriptive study with a cross-sectional design using secondary data from IFLS5 data in 2014 (n = 28,410). Socio-economic position (SEP) was calculated by Adult Equivalent Scale and categorized into 4 classes. Outcome is RAS. Mediating factors were psychosocial (stress), eating behavioral (food consumption), and systemic diseases. Descriptive analysis, chi-square and a series of logistic regressions were performed to analyze the data. Odds ratio (OR) and 95% confidence interval (CI) were used to report the results. RESULTS: Only 18.39% of IFLS5 respondents experienced the incidence of recurrent aphthous stomatitis in 2014. The bivariate (chi-square) results showed that there was a relationship between the incidence of RAS and the related independent variables. Logistic regression showed the highest possibility of RAS in respondents aged 18-34 years, female, unmarried, high school education level, living in the city, having frequent stress levels, having food habits that frequently drinking soda, sweet foods, chili sauce, fried food and has systemic diseases such as, asthma, cancer, rheumatism, and digestion. The lowest SEP group had the highest probability of occurrence of RAS over the other groups among the different models. CONCLUSIONS: There are several factors that determine the incidence of RAS. There was a monotonic gradient of inequality in RAS according to SEP group. This study might be useful to provide information regarding the relationship of determinants factors with the incidence of RAS to prevent it and promote oral health in the future.

The use of mouthguards and related factors among basketball players in Indonesia.

BACKGROUND: Basketball is a sport with a higher injury rate. Regardless, few basketball players use mouthguards, which predisposes them to injuries. The use of mouthguards (UoM) could be related to several factors. This study aims to identify factors associated with UoM and to construct a model from the factors among basketball players in Indonesia. METHODS: Through convenience sampling, a total of 286 among basketball players in Indonesia was included in this cross-sectional study. These participants filled out online a modified questionnaires regarding demographic and several factors related to UoM. The data was analyzed using chi-square test, independent-sample t-test, binary logistic regression, and structural equation modeling (SEM). RESULTS: There were 286 players. 127 of them were males and 159 were females. Of them, 86 (30.1%) used mouthguards. Age, duration (in year), and weekly practicing basketball (in hour) were all significantly different between mouthguards users and non-users with (p = 0.005, p = 0.036 and p = 0.035), respectively. The UoM was significantly associated with level of awareness, injury experience, social support, and oral health professional (OHP) support with (p = 0.002, p < 0.001, p < 0.001 and p < 0.001), respectively. This result was also supported by a variety of variables' ORs, which range from 1.28 to 5.97. The coefficient of determination (R2) was 0.27. CONCLUSIONS: The UoM among basketball players in Indonesia was related to several factors, including the level of knowledge, level of awareness, duration of basketball career, injury experiences, social support, and oral health professionals' support which was constructed to propose a model. The model could explain 27% of the relationship between variables and UoM among Indonesian basketball players. This model will be useful for more comprehensive initiatives to promote oral health. It might be applicable for other countries as well as other sports communities / physical activities.

The Effect of Educational Video on COVID-19 and Dental Emergency Literacy among Students during Pandemic Era.

OBJECTIVES: To determine (1) the level of knowledge regarding COVID-19 and dental emergency (DE) along with the factors that might be associated (2) with the effect of educational video on the level of knowledge among nondental students. MATERIALS AND METHODS: This online pre-experimental study used an educational video regarding COVID-19 and DE with a one-group pretest-posttest design toward the undergraduate nondental students (n = 363) from six public universities in West Java Province, Indonesia, aged 18 to 22 years. A Google Form was used and convenience sampling was undertaken. STATISTICAL ANALYSIS: The chi-squared, Mann-Whitney, Wilcoxon, and Spearman correlation tests were performed. Cohen's d effect size was used to assess the effect of videos. RESULTS: Most of the respondents were females around 20.36 ± 0.94 years. There is a statistically significant difference between the pre- and posttest knowledge score for COVID-19 (p <0.001) and DE (p <0.001). The "with dental school" group had a significantly higher pretest score in DE literacy than the "without dental school" group. There is a significantly positive linear relationship between the frequency of watching videos and the posttest score. The effect size was 1.03 and 0.8 for COVID-19 and DE, respectively. The majority of students agreed (agree and very agree) with all statements regarding video education. CONCLUSIONS: The level of knowledge regarding COVID-19 and DE increased from 5.30 to 6.75 and 6.58 to 8.02, respectively. The associated factors were the type of university and the frequency of watching videos. Educational intervention seems to have a great effect in increasing the knowledge of nondental students.

Oral health inequality among Indonesian workers in South Korea: role of health insurance and discrimination factors.

BACKGROUND: The health of migrant workers is becoming an important public health issue. Although there are an increasing number of migrant workers in Korea, the health status in migrant populations remains unknown. The aims of this study were (1) to evaluate the association between income and self-rated oral health (SROH), and (2) to assess the role of health insurance and self-perceived discrimination in the association between income and SROH among Indonesian migrant workers in Korea. METHODS: Information about self-reported income, SROH, coverage/utilization of health insurance (HI), living difficulties related to oral health (LDROH), oral health literacy (OHL), and discrimination were obtained from Indonesian migrant workers in Korea (n = 248). The main explanatory variable was income, and SROH was an outcome variable. Logistic regression analyses were performed controlling for age, gender, HI, LDROH, OHL, and discrimination. The paths from income to SROH were analyzed using the Partial Least Square-Structural Equation Model (PLS-SEM). RESULTS: Among Indonesian migrant workers, the lower income group had the highest probability of a poor SROH compared to the higher income group. The variables showing a high explanatory power were discrimination among the low income group and HI among the middle income group. In PLS-SEM, the variables such as HI, LDROH, OHL, and discrimination contributed 11% to explaining the association between income and SROH. CONCLUSION: A monotonic gradient was revealed among migrant workers according to the association between income and SROH. Discrimination and HI contributed to oral health inequalities.

Neo-Marxian social class inequalities in oral health among the South Korean population.

AIM: The aims of this study were to examine inequalities in periodontitis and tooth loss among South Korean adults using the Wright's Neo-Marxian social class (NMSC) indicator and to assess the impact of material, psychosocial, health behavioural and workplace environmental factors in the association of social class with oral health. METHODS: This study used the data from the 4th Korea National Health and Nutrition Examination Survey with 6710 participants aged 19-54 years old. Participants were classified into 12 social class positions based on the Wright's social class map. Healthy gum and absence of tooth loss were the health outcomes. Mediating factors were material (M), psychosocial (PS), health behavioural (HB) and workplace environmental (WPE) factors. A series of logistic regressions were performed to analyse the data. Odds ratio (OR) and 95% confidence interval (CI) were used to report the results. RESULTS: For the absence of periodontal pockets status, expert supervisors were the healthiest periodontal group among the social classes (OR = 2.15 95% CI 1.59-2.90) in the age and gender adjusted model. For the absence of tooth loss, skilled workers had the highest OR for absence of tooth loss (OR = 1.64 95% CI 1.31-2.05) in the age- and gender-adjusted model. For absence of periodontal pockets, the explanatory power of the M factor was the highest in all social class positions except for nonskilled supervisors followed by the HB factor. Additionally, the absence of tooth loss had a fairly similar pattern. The explanatory power of the M factor was the highest in all social class positions except for the petty bourgeoisie (highest: HB) and nonskilled supervisors (highest: WPE) followed by the HB and WPE factors. CONCLUSION: There were nongradient oral health inequalities among the South Korean population according to the NMSC. Oral health promotion programmes that focus on changing the socioeconomic environment and health behaviours should be implemented.
