Abstract

Jakarta is the capital city of Indonesia which is surrounded by its satellite cities Bogor, Depok, Tangerang, Bekasi. Nonetheless, scarce information are available of the current oral health of children. Objective: The study aims to describe caries and gingival status among 5 and 12 years old children in Jabodetabek. Jabodetabek is an abbreviation of Jakarta, the capital city of Indonesia, and the satellite cities in its surrounding (Bogor, Depok, Tangerang, Bekasi). Methods: The survey was done in 2014 and had already got ethical approval. Design of this study was crosssectional. Subjects were 5-year-old and 12-year-old Indonesian children living in Jabodetabek, selected using cluster sampling method. One trained examiner performed the clinical examination. Caries experience was measured using DMFT index, severity of decayed teeth was assessed using PUFA index, gingival status and oral hygiene were measured by Loe and Sillness modified index. Results: A total of 390 5-year-old and 458 12-year-old children with balanced proportion between girls and boys participated in the survey. The prevalence of caries experience among the 5-yearold children and 12-year-old children were 90% and 84% respectively. The mean DMFT and DT scores among the 5-year-old children and 12-year-old children were 7.5±5.5 and 6.8±4.8; 3.2±2.2 and 2.9±2.1 respectively. Pulp involvement were apparent in 45% and 23% of caries in 5 and 12-year-old children respectively. Most children, 45% 5-year-old children and 92% 12-year-old children had substantial amount of plaque. Moreover, 68% 12-year-old children had gingivitis. Conclusion: Dental caries were prevalent among 5 and 12-year-old Indonesian children in Jakarta and its satellite cities. The oral health condition of most of the children were poor

Abstract

Previous surveys have indicated that the majority of Indonesian children have poor oral health. However, scant information is available on children’s oral health related quality of life (OHRQoL). The purpose of this study was to assess reliability as well as discriminant and convergent validity of Child Oral Health Impact Profile-Short Form 19 (COHIP-SF 19) Indonesian version. Methods: The Indonesian version of COHIP-SF 19 was developed according to the guidelines for the cross-cultural adaptation process. The instrument was tested among 529 children between 12 – 15 years old who were randomly selected from six junior high schools in Jakarta. The psychometric testing included internal consistency reliability, test-retest reliability, discriminant validity, and convergent validity. Results: Mean age of the participants was 13.3±0.9 years and 54% of the participants were female. The mean COHIP-SF 19 score was 57.8±8.8 and the median was 58 (range 27 – 75). The internal consistency and test-retest reliability was excellent for COHIP-SF 19 score with Chronbach’s alpha 0.83 and intra-class correlation coefficient 0.81. Children with active decay, untreated caries with pulpal involvement, and gingivitis had significantly lower COHIP-SF 19 scores (p-value ≤ 0.030). Correlation between COHIP-SF 19 score, subscale scores and clinical severity as well as self-rated general or oral health were very low to low (rs = 0.04 – 0.27, p-value ≤ 0.028), after adjustment for children’s age and gender. Conclusions: The Indonesian version of COHIP-SF 19 was successfully developed to be used as an OHRQoL instrument for Indonesian school-age children. The internal consistency, test-retest reliability, discriminant validity, and convergent validity of COHIP-SF 19 Indonesian version were confirmed.

Abstract

Fluoride and calcium play an important role in the prevention of dental caries, promoting the inhibition of demineralization and the increase of remineralization. Objective: To investigate the effects of milk with/without the combination of tea and 0.2% NaF on enamel demineralization using micro-computed tomography (microCT). Methods: The coronal parts of 40 extracted sound premolars were prepared as tooth blocks. An unvarnished occlusal surface window was created for each tooth by covering the occlusal surface with a 3x5 mm2 sticker and painting all other surfaces with an acid-resistant varnish. These blocks were randomly allocated into four groups that were immersed in remineralizing solutions for 26 minutes: Group A, milk; Group B, milk and tea; Group C, milk and 0.2% NaF; and Group D, deionized water (control). Results: After 3 days of immersion in a buffered demineralization solution at pH 4.4, micro-CT scans were taken. The mean grayscale values and the standard deviations are: 98.1 ± 24.0; 90.8 ± 9.1; 92.6 ± 21.4; 81.1 ± 20.3, respectively. The mean grayscale values were significantly different among the four groups (p

Abstract

Epidemiological study of tooth brushing is essential to evaluate dental health of a country. Objective: To obtain data on tooth brushing frequency, time of day and duration from adults and children in Jakarta, Indonesia. Methods: Toothbrushes containing data loggers were distributed to 120 random families in Jakarta to record how many times a day, when and for how long subjects brushed their teeth. The families were each composed of a mother, father and two children aged between 6 and 15 years. Results: The mean brushing frequency of the population was 1.27 times per day. The majority of the tooth brushing (46%) was performed in the morning. The mean tooth brushing duration of this population was 57.29 seconds. The mothers’ tooth brushing frequencies tended to be higher than that of the other family members, and the fathers tended to brush their teeth longer. Conclusion: Effective education aimed at increasing both the duration and frequency of tooth brushing from once to twice per day is urgently required in Indonesia.
