Objective: To determine the frequency distribution of dental anomalies in people with Down syndrome. Material and Methods: This cross-sectional study was developed in Jakarta, Indonesia, and evaluated 174 individuals with Down syndrome aged 14-53 years. Were collected information regarding the tooth number, tooth size, shape, and structure. Descriptive statistics were used to calculate the absolute and relative frequencies. The Pearson chi-square test was used in bivariate analysis. The significance threshold was set at 5%. Results: There were 70 female subjects (40.2%) and 104 male subjects (59.8%) with an average age of 19.2 years. In terms of anomalies of tooth number, hypodontia (80.9%), supernumerary teeth (12.4%), and combined hypodontia and supernumerary teeth (12.4%) were identified. In terms of anomalies of tooth size, microdontia (98.8%) is the most common anomaly. Anomalies of tooth shape included fusion (66.67%) and talon's cusp (33.3%), whereas anomalies of tooth structure included enamel hypoplasia (70.8%), enamel hypocalcification (4.2%), combined enamel hypoplasia and hypocalcification (12.5%), and tooth discoloration (12.5%). Conclusion: Individuals with Down syndrome in Jakarta showed a high prevalence of dental anomalies, with hypodontia and microdontia being the most common anomalies showing a tendency to occur predominantly in males.
