Bilateral Idiopathic Root Resorption: An Unusual Case Report

Abstract

External root resorption in permanent teeth can occur as a result of a multitude of local and systemic factors. Root resorption that is idiopathic or occurring without any identifiable underlying cause is an unusual phenomenon. The aim of this case report is to present a case of a patient with multiple idiopathic external apical root resorptions. This case is unusual in that extensive resorption is found bilaterally only in the distal roots of mandibular first molars. The pattern of severe resorption appears to be unique. No significant systemic, dental, or familial findings could be identified as a possible cause.
