Purpose: This study was conducted on a randomly selected group of secondary school adolescents in the Sadar Upazila under Cox's Bazar to assess the incidence of developmental dental (Deciduous, permanent and Mixed Dentition) anomalies concerning age, gender, and the relationship between jaws and teeth. Methodology: A sample survey by an oral examination of 198 school students, 11–16 years of age, was drawn from a Kalatali, Cox's Bazar District school Bangladesh who were available on October 19, 2019. Our participants were limited to students whose parents were agreed to participate in the survey and provided informed consent. Clinical examination was performed to identify the prevalence of developmental dental anomaly using portable light, dental mirror, and oral explorer. Dental abnormalities were discovered after examining the complete maxillary and mandibular arch. Results: Of the total respondents under the study, 56.6% were female, and 43.4% were male. Among the diagnosed disturbances, developmental anomalies in upper lateral incisors prevailed in 34.3% of cases. The cusp of Carabelli appeared to be the most dominant one covering almost 73.9% of the existing coverage of anomalies. However, the presence of the cusp of Carabelli in the permanent dentition was found in 76.2% of cases. Conclusion: Out of several dental anomalies, cups of Carabelli came out as the most prevalent dental anomaly among the sample shows 11.15 Chi-square value of the study subjects.
