Impacted supernumerary tooth developed under palatal polyp.
We present a rare case of an infant's palatal polyp associated with an impacted supernumerary tooth. We have previously reported three cases of palatal polyps in infants [1]. In one case, after surgical removal of the palatal polyp at the age of 1 year and 8 months, the lesion subsequently began swelling. A periapical radiograph at the age of 2 years and 9 months revealed a small calcified mass in the maxillary left incisor region. The swelling was kept under observation, the calcified mass developed gradually and was removed surgically at the age of 5 years and 5 months. The removed calcified mass was clinically diagnosed as an impacted supernumerary tooth and this was confirmed histologically. Histological findings did not indicate any relationship between the palatal polyp and the impacted supernumerary tooth.
