Neonatal teeth: Importance of histological findings in management update.

Background: Presence of teeth in a newborn represents a rare finding and a disturbance of biological chronology of teeth. The aim of this paper is to report two cases with neonatal teeth histologically examined.

Case Report: In this paper two cases of patients with neonatal teeth are reported and histological examinations of three extracted teeth are described. We report an exceptional finding in one of the neonatal teeth microscopically examined: a massive inflammatory infiltration in the pulp tissue similar to that in pulpitis.

Results: The management of natal and neonatal teeth usually includes the extraction in case of ulceration on the tongue or severe tooth mobility to prevent accidental inhalation or feeding disturbances. The presence of an inflammatory infiltration of pulp tissue in one of teeth histologically examined suggests to review the indications for extraction considered to date.

Conclusion: The management of natal and neonatal teeth should consider the presence of an inflammatory infiltration of pulp tissue. An anamnestic interview is advisable in ordert to deeply investigate about possible behaviours of the child due to pain or discomfort.
