Multirooted- Bilateral Maxillary and Mandibular First and Second Premolars- A Rare Anatomical Variation

Rupali Karale*,Jayshree Hegde,Srirekha A,Sravanthi Y

Introduction: A thorough understanding of root canal anatomy and morphology is required for achieving high levels of success in endodontic treatment .The possible anatomic configurations of premolars are well documented in the literature, except for the small incidence of bilateral multi-rooted maxillary and mandibular premolars with three canals.

Objective: To report a rare case of bilateral morphological root aberrations in maxillaryand mandibular first and second premolars in a female patient.

Case report: A 36 yrs old female patient was evaluated for painful maxillary left Ist and IInd premolars. Physical examination revealed no alteration or apparent mental retardation. Panoramic and periapical X-rays revealed multiple roots and canals in maxillary and mandibular Ist and IInd premolars. This article reports and discusses the treatment recommendations for an unusual occurrence of three canals in both the first and second maxillary premolars in the same patient drawing particular attention to radiographic interpretation and access management.

Conclusion: Findings emphasize the importance of radiographic assessment for diagnosing multiple roots which might present unusual characteristics such as multiple and bilateral appearance. The absence of a syndrome should not be used to rule out the possible manifestation of this morphologic variation.
