Abstract

Tooth impaction refers to situations where a tooth fails to erupt due to mechanical blocking and remains unerupted beyond the normal time of eruption. It is commonly found in permanent dentition, but rarely in deciduous dentition. Tooth impaction is caused by systemic or local factors, and most common etiology is odontoma. Odontoma is also commonly found in permanent dentition, and rarely in deciduous dentition. We are presenting case of 4 year and 4 month year old girl, who had impacted and disto-angulated lower left deciduous second molar due to odontoma. We removed odontoma and performed orthodontic traction of impacted lower left deciduous second molar. Then, the impacted primary molar was erupted and acceptable occlusion was obtained.

Key Words: Tooth impaction, Odontoma, Deciduous dentition
