FERNANDES, Ana Paula et al. Impactation of first permanent molar in a patient with cleft lip and palates. Stomatos []. 2011, 17, 32, pp. 55-64. ISSN 1519-4442.

The paradental cyst is an odontogenic inflammatory cyst, always related with vital molars, partially erupted, associated with pericoronaritis. Usually affects lower third molars, and more rarely can occur in others teeth, causing eruption disturbances. The impactation of lower first permanent molars is rare and a few cases have been reported in the literature. The most frequent tooth that presents impactation is the lower third molar followed by the maxilar third molars. Its etiology may involve both local and systemic factors. This case report has the objective to present a case of impactation of a first permanent molar caused by the presence of a paradental cyst, as well the treatment that was conducted.
