Unusual impaction of a primary lateral incisor.

Impactions in the primary dentition are rare and usually are found in the posterior regions. They tend to be asymptomatic and are found on routine radiographic examination when the patient is in the mixed dentition or permanent dentition stage. A literature review shows no reports of impactions of primary incisors, but there is mention of possible etiologies for anterior impactions. An impacted lateral primary maxillary incisor was identified during routine radiographic examination of a young child. There is no known etiology for this particular case. Treatment options are discussed.
