Radix entomolaris – A case report

Resumo

A comprehensive knowledge on the root canal
anatomy is a basic prerequisite for the endodontic treatment
successful. Mandibular molars may have an additional root located
lingually (radix entomolaris) or buccally (radix paramolaris).
In the literature, this anatomy variation is considered rare in
Caucasian 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 report: The purpose of this study was to
report a clinical case of successful endodontic treatment in a
mandibular molar with pulp necrosis and characterized as radix
entomolaris in which the use of magnification and ultrasonic tips
(the “microsonics concept”) was fundamental to the management
of the variations in the internal anatomy. Conclusion: A better
understanding of the root canal morphology is essential for
endodontic treatment success, as well as the use of technologic
advancements in Endodontics including computed tomography,
ultrasonic tips and the operating microscope.
