[Show abstract][Hide abstract] 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.

[Show abstract][Hide abstract] ABSTRACT: Adenomatoid odontogenic tumor (AOT) is a benign (hamartomatous), non-invasive lesion with slow but progressive growth. There are three variants of AOT: follicular, extrafollicular, and peripheral. This report illustrates an unusual case of AOT, i.e., arising within the periodontal ligament. A boy was brought in by his parents for evaluation of a gingival swelling. Periapical radiograph revealed thickening of the periodontal ligament with foci of calcification. Clinical diagnosis was peripheral ossifying fibroma. Biopsy was performed and microscopic examination revealed the presence of an AOT. The patient has been followed-up for eleven months without recurrence.
[Show abstract][Hide abstract] ABSTRACT: Supernumerary tooth/teeth (ST) are a well recognized clinical phenomenon defined as teeth that are additional to the normal complement. The purpose of this report was to describe 3 patients who developed multiple sequential ST. All patients were boys between 8 and 12 years old without significant medical history. In 2 cases, the ST were discovered while investigating the nonexfoliation of primary teeth, whereas in the other they were an occasional finding on a radiograph taken for orthodontic purposes. All patients were kept under close follow-up ofter treatment. The 3 patients collectively developed a total of 17 ST with 9 found in a single patient, over a 5-year period. This article demonstrates the importance of clinical and radiographic follow-up of ST patients, regardless of age, family history, or systemic condition.
