Tooth impaction is defined as any tooth that fails to erupt into a normal functional position and remains unerupted beyond the time at which it should normally erupt. Reports of impaction and eruption failure in primary teeth are relatively rare compared to permanent teeth. Several factors contribute to the impaction of a deciduous tooth. Impacted primary teeth may be associated with defects in development and eruption of their permanent successors, long-term observation is therefore necessary until the permanent successors erupt. This report describes the diagnosis and treatment of a 8-year-old boy who presented with an impacted maxillary first primary molar.
