Resumen

Introduction and objective: Dental anomalies are congenital malformations of tooth tissue that occur due to lack or increase in its development; these can be in shape, number, size and position. Such anomalies can affect maxillary length and occlusion. The aim of this study was to determine the prevalence of dental anomalies in a sample of orthodontic patients in Cali, Colombia. Materials and methods: Descriptive cross sectional study, with 277 panoramic radiographs of patients attending an orthodontic clinic between 2007 and 2011. Radiographs that were distorted, stained, elongated or blurred were excluded. Dental anomalies studied were, size: macrodontia and microdontia; form: fusion, gemination, concrescence, laceration, invaginated tooth, evaginated tooth, roots supernumerary enamel and pearls; Number: anodontia, hypodontia, oligodontia, anodontia and supernumerary teeth; and the position of the anomalies: retention and transposition. Results: Dental anodontia was the most prevalent dental anomaly (14.4%) in the patients, followed by retention (10.8%), microdontia (5.1%) and supernumerary teeth (3.6%). 3.8% of men suffered transposition, while none of the women presented this abnormality (p = 0.009). A significant relationship between the presence of supernumerary teeth and the presence of retention (p = 0.047) was found. Conclusions: The most frequent dental anomalies in the patients studied were anodontia, retention, microdontia and supernumerary teeth. In the sample, men showed a higher probability of transposition than women. There is a relationship between retention and supernumerary teeth.
