Background: Down syndrome (DS) is a chromosome disorder due to the presence of all or part of a third copy of chromosome 21 (trisomy 21) caused by a failure in chromosome segregation. Following Riset Kesehatan Dasar (RISKESDAS) in 2013, the number of people with DS in Indonesia increased compared to 2010, with an estimated 924 children with DS in Surabaya. Data regarding caries status in children with DS in Surabaya is limited. Objective: To evaluate parents’ behavior (predisposing, enabling, and reinforcing factors) related to the caries status of children with DS. Methods: This observational analytic cross-sectional study included children aged ≤18 years with DS and parents who were members of the Parents' Association of Children with Down Syndrome (POTADS). Caries status were measured using the DMF-T/def-t score, and parents were asked to fill out a questionnaire. Data were analyzed using Spearman’s correlation test. Result: We included 46 children with DS in this study. The DMF-t / def-t index of children with DS (7.2) was categorized as very high according to WHO. There was a significant relationship between lack of knowledge of parents and caries status in children with DS. Enabling factors and reinforcing factors were not significantly correlated with caries status. Conclusion Parents' behavior is correlated with the caries status of children with DS. All combination of three factors behavior, including predisposing, enabling and reinforcing, are needed to reduce the number of caries in children with DS.

Objective: To describe various local and systemic factors as the cause of gingivitis and to find out the main etiological factors of gingivitis in children with DS. Methods: We searched PubMed and Google Scholar for Indonesian and English references either in the form of textbook, research results, reviews, and internet articles on the topic. We screened and selected the relevant articles for inclusion into the review. Results: In children with DS, apart from poor oral hygiene, the increasing incidence of gingivitis is caused by changes in other local factors related to systemic factors, such as oral dysfunction, dental and gingival abnormalities, changes in the oral microbial profile, and salivary characteristics. Furthermore, systemic immunodeficiency, changes in inflammatory mediators and proteolytic enzymes, and intellectual subnormality are considered as systemic factors. Conclusion There is no main etiological factor of gingivitis in children with DS since various local and systemic factors are interrelated with each other causing gingivitis. The severity of gingivitis in children with DS presumably were caused by the systemic factors. Furthermore, good oral hygiene habits and the dentist's intervention in periodontal health can significantly reduce gingivitis in DS patients.
