ABSTRACT
PURPOSE: To compare the effects of gels containing 2.5% and 5% carboxymethyl chitosan amorphous calcium phosphate (CMC-ACP) on the microhardness of primary tooth enamel. METHODS: Twenty-four tooth specimens were demineralized with 37% phosphoric acid and divided into four groups: an untreated control group, a positive control group treated with casein phosphopeptide amorphous calcium phosphate, and two groups treated with 2.5% and 5% CMC-ACP gel, respectively. The enamel surface hardness was then measured with a Vickers hardness tester. RESULTS: In terms of Vickers Hardness Number (VHN), the degree of alteration in tooth surface microhardness was 77.83 ± 13.44 in the 5% CMC-ACP group and 52 ± 6.93 in the 2.5% CMC-ACP group (P = 0.002). The inter-group difference in the surface hardness change was significant (P < 0.05). CONCLUSION: The 5% CMC-ACP gel increased the hardness of primary tooth enamel to a greater degree than the 2.5% CMC-ACP gel.

Abstract Objective: To evaluate the oral hygiene status of children with Down syndrome using the busy book Ayo Sikat Gigi as an educational toy. Material and Methods: We ran an experimental study involving 25 educable and trainable children with Down syndrome, comprising 17 males and 8 females aged 7-12 years, who were free from other disabilities and did not use orthodontic or prosthodontic appliances. Parents were instructed to educate their children using the busy book Ayo Sikat Gigi and also to guide their children in brushing their teeth effectively at home. We evaluated the OHI-S score over two visits, one before and the other after education using the busy book Ayo Sikat Gigi over a 7 day period. The Wilcoxon test with the p-value set at 0.05 was used Results: It was noted a statistically significant decrease in the OHI-S scores of children with Down syndrome (p<0.05), reflecting an improvement in their dental health, after education using the busy book Ayo Sikat Gigi (median scores before and after education: 2.30 and 1.84, respectively) Conclusion: The busy book Ayo Sikat Gigi is a highly effective educational toy for children with Down syndrome, and in our study, it was demonstrated to decrease their OHI-S scores after education for 7 days.

Abstract Objective: To determine the frequency distribution of gingivitis and oral hygiene in individuals with Down syndrome. Material and Methods: This study used a cross-sectional descriptive method and the subjects were 174 individuals with Down syndrome aged ≥14 years attending type C (intellectual disability) special needs schools in Jakarta. Gingivitis was measured using the gingival index, and oral hygiene was measured using the Simplified Oral Hygiene Index (OHI-S). The measurement of the two components of plaque and calculus was completed on six teeth on different surfaces, including the facial side of three maxillary teeth, the lingual side of the two posterior mandibular teeth, and the labial side of one anterior mandibular tooth. Descriptive statistics were used to calculate the absolute and relative frequencies Results: 3.4% had no gingivitis, 47.2% had mild gingivitis, 40.8% had moderate gingivitis, and 8.6% had severe gingivitis. Regarding oral hygiene, 28.2% had good hygiene, 49.4% had fair, and 22.4% had poor hygiene Conclusion: Individuals with Down syndrome had a frequency distribution of gingivitis mainly in the mild and moderate categories, and a majority of subjects had fair OHI-S.

OBJECTIVES: One of the most common ways to communicate to children with autism spectrum disorder (ASD) is by using pictures. This study was conducted to identify the easiest perception of dental visit by children with ASD when using pictures as printed photographs. MATERIALS AND METHODS: Purposive sampling was used to recruit participants from a school for children with special needs in south Jakarta. Semi-structured interviews were conducted with 10 autistic children aged 13-17 years, 2 parents, and 2 teachers. Open-ended questions were asked to participants regarding pictures of dental clinic personnel and activity. Conversations were noted, tape recorded, and then categorized to extract a theme. The data were analyzed using Dedoose mixed methods software. RESULTS: Most respondents showed a positive perception of the dental visit pictures. Many of the pictures were easily recognized by children with ASD, but some failed to be understood. Caretakers not only gave their perception but also recommendations for improvement of the pictures. CONCLUSIONS: Dental visit pictures could be used as useful communication tools for children with ASD. Based on the results, the pictures related to dental visit were generally easy to understand, however, some needed correction to be comprehensible.
