AbstractAims: The aim of the present study to analyze the prevalence of supernumerary teeth in a group of Bihar, India non-syndromic population.
Methods: A retrospective study was conducted in the Department of Dentistry, Jawaharlal Nehru Medical College and Hospital, Bhagalpur, Bihar, India, for 12 months. Total 50 non syndromic patients were included in this study. Panoramic radiographs and clinical records of patients above the age of 18 years and without any syndromic features were selected for the study. All the radiographs were examined for the presence of supernumerary teeth, their location, morphology, and number.
Results: Among the 4000 radiographs selected only 50 radiographs showed the presence of supernumerary teeth with a prevalence rate of 1.25%. Number of supernumerary teeth varied from 1 to 9 with a total of 100 supernumerary teeth. 45% of patients showed single supernumerary teeth whereas 24% showed two supernumerary teeth. One patient had 9 impacted supernumerary teeth Prevalence of supernumerary teeth was more in males compared to females with a ratio of 1.5:1. Among the 100 teeth, 90% were impacted, and 10 % were erupted. Maxillary posterior region (52%) was the most common location, followed by mandibular posterior region (33%). Maxillary right quadrant (40%) had a higher incidence of supernumerary teeth followed by maxillary left quadrant (27%). 40% of them were fully developed, whereas 22% of them had an evidence incomplete crown formation and 23% showed incomplete root formation. Based on morphology, supplemental form (60%) was the most common type followed by 32% showing tuberculate form and 8% odontomas.
Conclusion: We concluded that the knowledge about the supernumerary teeth is important for dental clinicians as they are relatively common but are detected as an incidental finding in a radiograph. A routine screening panoramic radiograph is mandatory for every patient to unveil this condition so as to enable the dentist in early diagnosis, intervention and prevent the possible complications associated with it.
