“…Therefore, it is prudent to better understand the tooth root morphology by means of 3D imaging technology to anticipate the challenge of root canal treatment. It has been reported that when extracanals in the mesiobuccal root are suspected, the access cavity should be modified to locate their potential canal orifices [ 32 , 33 ]. Based on the present results, the cavity modification should be limited not only to horizontal extension of the cavity but also to apical extension which is represented as floor troughing, to expose the buried canal orifices in the mesiobuccal root area, if present [ 32 , 33 ].…”

However, the chamber floor should not be troughed more than 2 mm to avoid jeopardizing the tooth integrity and possible tooth perforation [ 8 ].…”

The aim of this study was to determine MB2 canal detectability in maxillary first and second molars obtained from a Saudi population using micro-CT. Maxillary first (n=35) and second (n=30) molars were scanned with micro-CT technology. The number of canals was recorded, and in case of having more than one canal, the level of extracanal detection was analyzed. The presence of extracanal was categorized based on the level they were first detected. Among the maxillary first molars, 28 (80%) and six (17%) teeth had two and three MB canals, respectively. Among the maxillary second molars, 24 (80%) and four (13%) teeth had two and three MB canals, respectively. The MB2 canal was detected at the chamber floor in 70% and 61% of the maxillary first and second molars, respectively. At 1 mm depth, the MB2 canal was found in 15% and 18% of the maxillary first and second molars, respectively. At 2 mm depth, the MB2 canal was found in 3% and 18% of the maxillary first and second molars, respectively. The remaining teeth had the MB2 canal at levels deeper than 2 mm. The MB2 canal was detected in 97% and 93%% of maxillary first and second molars, respectively. Among them, the MB2 canal could be immediately detected in 70% and 61% of the maxillary first and second molars, respectively, once the pulp chamber is exposed. However, the rest of the MB2 were observed at deeper levels in the root and this requires troughing preparation in the chamber floor.

“…When extra canals in the MBR are suspected, the access opening is extended on the mesial side to have a trapezoidal rather than a triangular shape (36,40,41,48,51,56). Next, the clinician should read the "road map" of the pulpal floor to locate potential canal orifices.…”

“…Next, the clinician should read the "road map" of the pulpal floor to locate potential canal orifices. This may include exploring the floor with an endodontic explorer (29,31,36,37,39,42,55,58), troughing the floor with round burs (31,36) or ultrasonic tips (41,49,56). In addition, staining the pulpal floor with a dye, performing the champagne test with sodium hypochlorite, visualizing canal bleeding points are important aids in locating canal orifices (2).…”

INTRODUCTION The knowledge of root canal anatomy is essential to ensure a successful outcome of surgical and nonsurgical root canal treatment. The aims of this article were to present 2 cases of maxillary molars with 3 mesiobuccal root canals and to review the available literature on this anatomic variation. METHODS The first case described a nonsurgical root canal treatment of tooth 16 in a 29-yearold man with the aid of a dental operating microscope. In the second case, an extracted maxillary right first molar was scanned by a micro-computed tomographic system and reconstructed 3-dimensionally using modeling software. RESULTS In both cases, the mesiobuccal root had 3 canals (type 3-2 in case I and type 3-3 in case II), whereas the distobuccal and palatal roots had a single canal. The literature review showed that the overall incidence of 3-canaled mesiobuccal roots in maxillary molars ranged from 1.3%-2.4% and that the most common root canal configuration was type 3-2. CONCLUSIONS Clinicians should always anticipate the presence of extra canals in maxillary molars and use all the available tools to locate and treat these.

“…The occurrence of 0.9 percent with a single root in the maxillary second molar was reported in an Indian population survey, but none with a single root canal was reported. (Gusiyska, 2010;Di Ventura et al, 2019)). Searching for a missing canal can result in iatrogenic mishaps, such as perforation or premature removal of the tooth(Table 2).…”

The dental professional should be familiar with the differences of number of root and root canal system anatomy, which at some aspects provides specific dental anomalies of tooth and helpful in analysing in the clinical field. The main aim for patients and doctors is to relive pain and maintain natural teeth with similar morphology. Root canal therapy is mostly the treatment of choice for teeth with pulpal and periradicular affected teeth. Effective treatment is required for good mechanical and chemical cleaning and shaping and provides a compact obturation under aseptic conditions with an inert filling material.The major reason for endodontic failure is the existence of untreated canals. A detailed diagnosis of the root canal system anatomy is a requirement for effective treatment of root canals. This review shows incidence of root and root canal variations in maxillary second molars. The presence of root canal orifices helps in diagnosis of preoperative radiographs and examination of the pulp.
