Abstract
This study aimed to survey the demographic profile of supernumerary teeth (ST) in Brazilian children and adolescents. A retrospective analysis was carried out of all nonsyndromic patients with ST attended at the Pediatric Oral Surgery Service of the Universidade Federal de Minas Gerais between 1995 and 2004. Diagnosis of ST was based on clinical and radiographic examination. Chi-squared test was used for statistical analysis. This study included 460 ST found in 305 patients. Radiographic assessment (32.1%) was the main care-seeking reason and also the means through which most (97.6%) permanent ST were identified. Most cases were single (63.0%), conical (44.6%), and unerupted (76.8%) ST. Most teeth were fully developed (41.3%), normally orientated (78.9%), placed in a palatal/lingual-sagittal position (84.1%), adjacent to the crown of permanent teeth (50.2%) (P < 0.001). The most frequent clinical complication was permanent teeth displacement (36.0%). Treatment was surgical removal followed by orthodontics (61.6%). The demographic profile of ST herein presented will be useful to provide additional epidemiological information. A wide range of factors should be considered when evaluating ST. In addition, it is essential to detect ST as early as possible to avoid complications and to assure successful management. Even after treatment, patients must be followed up.
