CONGENITAL DENTAL ANOMALIES IN THE PRIMARY DENTITION

Abstract

Aim:The purpose of this study was to investigate the prevalence of congenital anomalies in the primary dentition in preschool children populations.Material and Methods:Data pertaining to a total of 935 children (487 boys and 448 girls) in the 2–5 year age-group who visited the Department of Pedodontics Clinic at the Dokuz Eylul Univeristy Hospital, Izmir, Turkey between january 01, 2016, anddecember 31, 2017were all panoramic radiographs and photograph restrospectively analyzed. The presence of hypodontia, hyperdontia (supplemental and mesiodens), and double teeth (fusion and gemination) were recorded.Statisticalanalysis was performed usingFisher's exact testand chi-square test. Results:Dental anomalies were found in 2.7% of children. Double teeth were the most frequently observed anomaly (1.4%), followed by hyperdontia(0.9%) and hypodontia (0.5%). Unilateral missing teeth were more frequently observed than bilateral missing teeth. All supernumerary teeth were located in the primary maxillary incisor area. Dental anomalies were significantly more frequent (p=0.001) in boys (1.6%, n=15) as compared to that in girls (1.1%, n=10).Radiographic examination showed 36.0% of the patients (9 children) had anomalies in the permanent dentition.Conclusions: Identification of primary dental anomalies at an early age is of great importance as it may help prevent malocclusions as well as functional and psychological problems.Anomalies in primary dentition exhibited a correlation with anomalies in permanent dentition.
