Prevalence of Supernumerary Teeth in Non-Syndromic Northern Malaysian Population

Objective: To describe the distribution and characteristics of the supernumerary teeth among non-syndromic Malaysian population. Material and methods: A total of 10,200 patients between age of 18 and 35years who visited our department between January of 2015 and May of 2017 were seen. 108 patients with supernumerary teeth were found. Patients were assessed for age, sex, site, position and type of supernumerary teeth. Statistical analysis was carried out using chi square test for gender. Results: Of these 108 patients, 30 (28%) were females and 78 (72%) were males. A total of 48 (44%) patients reported with mesiodens, 24 (22%) patients having distomolars and 12 (11%) patients with paramolars and 24 (22%) patients having other types of supernumerary teeth. 78 (72%) patients had supernumerary teeth in the maxillary region and 24 (22%) patients in the mandible while only 6 (6%) patients had supernumerary teeth in both maxillary and mandibular region. Conclusions: The prevalence of supernumerary teeth in non-syndromic Malaysian population is 1.05 % with slight male predilection and mesiodens being the commonest. Clinical Significance: Knowledge about the supernumerary teeth can enable dentist in early diagnosis, intervention and prevent many possible complications associated with supernumerary teeth.
