Reactive fibrous hyperplasia associated with a natal tooth.

A natal tooth is that which is present in the oral cavity at the time of birth. Fibrous hyperplasia is a non-specific reactive lesion of soft tissues of unknown etiology usually associated with trauma or local irritation. Natal teeth can occur as an isolated dental finding, but many times they are associated wilh syndromes and developmental disturbances. This is a rare case, where in a natal tooth has led to the formation of a reactive fibrous hyperplasia in a four and half month old infant, a relationship not reported previously.
