Bilateral extensive idiopathic apical root resorption in supraerupted maxillary molars: a case report.

Multiple idiopathic external root resorptions of permanent teeth are an infrequent phenomenon. A case report of a patient with multiple idiopathic external apical root resorptions is presented. This case is unusual in that extensive resorption is found bilaterally in supraerupted maxillary molar teeth. The pattern of severe resorption affecting only maxillary supraerupted teeth appears to be unique. No significant systemic, dental, or familial findings could be identified as a possible cause.
