Timor-Leste struggles with problems of poverty and inequalities that underlie many health disparities, including oral health. This study aimed to determine the association between parental education and dental caries in school children aged 6 to 17 years from 40 randomly selected schools in 4 Dili subdistricts. A questionnaire and oral examination collected data and multivariable log binomial models were used for data analysis. Results indicate no association between parental education level and the prevalence of untreated decay in deciduous teeth ( P = .96). There was an association between parental education level and untreated decay in permanent teeth ( P = .03) and untreated decay overall ( P = .01). Children whose parents had higher education levels have approximately half the relative risk (aRR 0.47, 95% CI 0.25-0.89) of decay compared with children whose parents had low levels of education.

Introduction: This research compared the oral health status of school children in Dili (the capital of Timor Leste) in 2002 and 2014., Methods: The 2014 oral health survey of Dili's children replicated the methods of an AusAID-supported oral health survey conducted in 2002. Equal numbers of children were invited to participate from four age groups (6-8, 9-11, 12-14 and 15-17 years). For the 2014 survey, the subdistricts of Dom Aleixo, Cristo Rei, Metinaro and Vera Cruz were randomly selected for inclusion. A questionnaire was used to collect data on demographics and oral health behaviours. Oral epidemiological examinations were conducted by four dentists and five dental nurses., Results: The 2014 survey in Dili recruited 758 participants for the questionnaire and 655 children for the oral examination. In 2014, a lower proportion of children reported brushing their teeth the previous day (97% vs 100%, p =0.01) and a larger proportion reported having toothache (40% vs 19%, p <0.001) (sometimes to very often) during the previous 12 months. The mean number of decayed, missing or filled teeth in the primary plus permanent dentition (dmft + DMFT) was greater in 2014 than in 2002 (4.2 vs 3.5, p =0.01). There was no difference in the prevalence of decay in the primary dentition (39% vs 37%, p =0.61) or the mean number of decayed, missing or filled (dmft) teeth in the primary dentition in 2014 compared to 2002 (2.0 vs 1.8, p =0.47). However, the prevalence of decay in the permanent dentition was greater in 2014 (70% vs 53%, p <0.001) as was the mean DMFT (2.3 vs 1.7, p =0.04). The prevalence of gingival bleeding (65% vs 81%, p <0.001) and calculus (57% vs 86%, p <0.001) was lower in 2014., Conclusions: There was an increase in dental caries experiences in Dili school children between 2002 and 2014, associated with more permanent teeth dental caries experiences.

Timor-Leste is one of the poorest countries in the world. The aim of this article was to investigate the association between socioeconomic status (SES) and dental caries experience in children living in Dili. Four out of 6 Dili subdistricts and 40 schools were randomly selected. Equal numbers of school children from 4 age groups (6-8, 9-11, 12-14, 15-17 years) were invited to participate. Data were gathered via a questionnaire and an oral examination by dental practitioners. In bivariate analysis, decayed, missing, and filled teeth index for deciduous + permanent teeth (dmft) was higher in children from mid- to high-SES than low-SES schools (1.1, 2.2, P = .001). With age, having had a toothache and dental visiting in the past 12 months in the multivariable model, higher dmft was found in children from mid- to high- to low-SES schools ( P < .001). The primary dental caries experience was greater among children from mid- to high- than low-SES schools, which may be explained by high sugar consumption.
