“…The researchers [14][15][16][23][24] have reported cases of successful endodontic diagnosis and therapy using SCT. On the basis of previous reports, multi-slice CT was planned for a final diagnosis of the anatomic variations of the maxillary second molar.…”

We present a case of a patient with rare anatomy of a maxillary second molar with three mesiobuccal root canals and a maxillary third molar with four separate roots, identified using multi-slice computed topography (CT) and three-dimensional reconstruction techniques. The described case enriched/might enrich our knowledge about possible anatomical aberrations of maxillary molars. In addition, we demonstrate the role of multi-slice CT as an objective tool for confirmatory diagnosis and successful endodontic management.

Presence of missed canals results in unsuccess root canal treatment because of insufficient cleaning and obturation. The incidence of a maxillary second molar with two palatal roots and a mandibular second premolar with three roots has been rarely reported in literature. This case report describes the endodontic management of a maxillary second molar with two buccal and two palatal roots and mandibular second premolar with three separate roots. Successful endodontic treatment requires a detailed knowledge of root canal anatomy to overcome the anatomic variations of the root canal system. This would help in reducing endodontic failure due to incomplete cleaning and obturation.

“…During obturation, canal patency was maintained through the apically compacted gutta percha with a file or with a spreader of suitable taper while each canal was being obturated. Failure to recognize these extra canals and to obturate them with care can lead to acute flare-ups during treatment and subsequent failure in endodontic therapy (20,21).…”

Introduction: Accurate diagnosis of root canal morphology and anatomy is essential for thorough shaping and cleaning of the entire root canal system and consequent successful root canal treatment. In a mandibular second premolar, it is rare to find extra roots and canals. The anatomy of the pulp chamber floor in premolars with more than one canal usually reveals one lingual and two buccal orifices at the same level. Case Presentation: This case report explains nonsurgical endodontic treatment of a mandibular second premolar with three separate canals and three separate mesiobuccal, mesiolingual, and distolingual orifices. Discussion: Mandibular premolars have always proven to be an enigma to endodontist, as they exhibit a high degree of variability in their root canal morphology when compared to any other tooth in the oral cavity. Flat roots are much more likely to contain multiple canals and intercanal ramifications. In such cases, to obtain predictable results, high quality preoperative radiographs should be available at different horizontal angulations and carefully evaluated to detect the presence of extra root canals.
