Objective:Oral health-related quality of life (OHRQoL) questionnaires have been administered to children older than 6 years. Currently, the scale of oral health outcomes for 5-year-old children (SOHO-5) has been used to determine the OHRQoL through self-reports and parental proxy reports of children aged <6 years. This study was conducted to estimate the psychometric reliability and validity after adapting the SOHO-5 to the Indonesian language.Materials and Methods:The cross-cultural adaptation was tested in children aged 5 years old and their parents. The reliability and validity of the questionnaire were measured among 161 kindergarten children in Jakarta, along with a clinical examination for dental caries.Results:Cronbach's alpha coefficients for internal consistency were 0.89 and 0.86 for child's self-reports and parental reports, respectively. The test-retest reliability results were excellent based on repeated administrations in 27 children; the intraclass correlation coefficients were 0.81 and 0.94 for the parental reports and child's self-reports, respectively. No corrected item-total correlation value was lower than 0.30, allowing all items in the instrument to be included for data analyses. The construct validity of the child's self-reports showed that the Indonesian SOHO-5 total score was significantly associated only with the presence of dental caries (P < 0.001). The construct validity of the parental reports described that the SOHO-5 total score was significantly associated with proxy-rated oral health, the child's perceived dental treatment and satisfaction with the child's oral health (P < 0.001).Conclusions:This study showed the Indonesian version of SOHO-5 is a reliable and valid OHRQoL measure for 5-year-old Indonesian children.

Background This study aimed to evaluate the prevalence of tooth wear among preschool children in Jakarta, Indonesia, and examine the risk factors associated with its occurrence. Methods An epidemiological survey was conducted with a cross-sectional study design. The participants were recruited via cluster sampling. Tooth wear was clinically assessed by one examiner using the Basic Erosive Wear Examination (BEWE) criteria. The children’s caries experience was also recorded. The parents of the participating children completed a self-administered questionnaire to answer demographic questions about the children and gather information about the children’s diet and oral health behaviors as well as the parents’ dental health-related knowledge. The data were analyzed using the Chi-square test and binary logistic regression. Results A total of 752 five-year-old children were invited to participate, with 691 (92%) enrolling in the study. Tooth wear occurred in 23% (161/691, BEWE > 0) of the participants, in which 78% (125/161) had at least one moderate tooth wear status (BEWE = 2). The consumption of citrus drinks, fruit juice, and vitamin C supplement drinks, together with the child’s caries experience, the father’s education level, and the family’s socioeconomic status, were significantly associated with tooth wear. Conclusions The five-year-old preschool children in Jakarta had a relatively low prevalence of tooth wear. Those consuming more acidic drinks, those with a higher socioeconomic status, and those with an absence of caries experience had a higher risk of tooth wear.

The aim of this cross-sectional study was to assess knowledge related to tooth erosion among dental students in dental hospital, Jakarta. Data were collected by means of a self-applied questionnaires that were distributed among 90 participants from three dental hospitals in Jakarta. The response rate was 100 percent. Chi-square and Mann-Whitney tests were used for statistical analysis (p0.05). The majority of the participants had heard about erosion (95.6 percent). 33.3 percent of the students almost had not seen a patient with erosion, and 37.8 percent reported they saw a patient with erosion in a month at their dental hospital. 90 percent of the students were knowledgeable and well-prepared to diagnose the condition.
