RADIX ENTOMOLARIS: A CASE SERIES

Abstract

Introduction: Mandibular molars may have an additional root located lingually (radix entomolaris) or buccally (radix paramolaris), which, if not diagnosed, can lead to failure of endodontic treatment. The prevalence of this anatomic variation is 4.5-11.5% in Indian populations. Awareness and understanding of the presence of unusual external and internal root canal morphology contributes to the successful outcome of the root canal treatment.

Objective and case reports: The purpose of this study was to report 2 clinical cases of endodontic treatment in

mandibular molars with extra roots. Also mentioned are the modifications in the canal preparation, problems encountered during the treatment, common iatrogenic errors which occur during the treatment and factors which affect the prognosis.

Conclusion: A better understanding of the root canal morphology is essential for endodontic treatment success, as well as the use of technologic advancements including computed tomography, ultrasonic tips and the operating microscope.
