Characteristics of Non-Syndromic Supernumerary Teeth in (a Group of Turkish) Children

Introduction: The aim of this study was to investigate the prevalence, distribution, gender differences and characteristics of non-syndromic supernumerary (SN) teeth in children and adolescents.   Methods: In a 2 year cross-sectional study, a total of 16,986 patients aged between 6-14 years who visited our department between April 2014 and April 2016 were revised. 100 cases of supernumerary teeth were found. Patients with SN teeth were evaluated for demographic data (age and sex), location, morphology, classification and number of the SN teeth and related complications. The distribution rates of SN tooth types and the distribution of complications between sex and age groups were analyzed. Likelihood ratio test was used for statistical comparisons.   Findings: The prevalence of non-syndromic SN teeth was 0.59%. The mean age of cases included in the study was 13.88 years (65% male and 35% female). The most common type of SN tooth was conical type (50%), while the supplemental (29.6%), tuberculate (16.7%) and odontoma (3.7%) types were also found. 92% of the cases had one SN tooth. SN teeth were mostly located in the maxilla (95.6%) and were mostly unilateral (55.3%); followed by bilateral (23.7%) and midline (21.1%). There was no statistically significant difference between the distribution of SN teeth between males and females (p>0.05). At least one complication was found in 40% of the cases.   Conclusion: SN teeth can cause a variety of complications. Careful and early clinical and radiographic examinations in children are important in order to prevent complications of SN teeth.
