Abstract:
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.

Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
