RESUMO
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.
