Abstract
The paper describes the anatomical variation of four roots in a mandibular permanent first molar diagnosed using multiple angulated preoperative radiographs and its successful nonsurgical endodontic management. Careful observation and exploration of the pulpal floor using a dental operating microscope revealed a peculiar developmental root fusion line on the pulp chamber floor. Based on the above observation, a correlation between this unusual line and the existence of additional roots has been proposed and discussed.
Highlights
One of the most important aspects in contemporary endodontics is a thorough knowledge of the internal and external root anatomy [1]
Anatomical variation is prevalent in many teeth, with some teeth having as many as 5 separate roots [4] or even seven [5, 6] or eight [7] separate root canals
The purpose of the present paper is to report the successful nonsurgical endodontic management of a fourrooted permanent mandibular first molar with each root containing its own independent root canal and to discuss a peculiar observation of the pulpal floor
Summary
One of the most important aspects in contemporary endodontics is a thorough knowledge of the internal and external root anatomy [1]. Additional roots and root canals if not detected could lead to endododontic failure [2]. A thorough knowledge of the root and root canal morphology and a good anticipation of their possible morphological variations will help reduce endodontic failure caused by incomplete debridement and obturation [3]. The mandibular first molar, or the “6-year molar,” which is the largest tooth in volume and most complex in root and canal anatomy, is possibly the most treated and least understood posterior tooth [3]. The purpose of the present paper is to report the successful nonsurgical endodontic management of a fourrooted permanent mandibular first molar with each root containing its own independent root canal and to discuss a peculiar observation of the pulpal floor
