Dimension, Anatomy and Morphology of the Mesiobuccal Root Canal System in Maxillary Molars

Morphologic Variations of Maxillary Molars Palatal Root and the Importance of Its Knowledge for Endodontic Practice: A Case Series

“…4 However, due to the complexity of the root canal system, some variations have been reported. [1][2][3][4][5][6] Clinical studies confirm the presence of four root canals on maxillary first molars as the anatomical feature most frequently found. Wolcott et al 7 observed two canals in the mesiobuccal root in 61.1% of cases, and Buhrley et al 3 in 71.1%.…”

“…[1][2][3][4][5] The maxillary first molar usually presents three roots and four canals (one canal in the palatal root, two in the mesiobuccal root and one in the distal root). 4 On the contrary, the maxillary second molar often shows three roots and three canals (one canal in the palatal root, one in the mesiobuccal root and one canal in the distobuccal root).…”

Assessment of canal centering ability and topography of three nickel- titanium rotary systems

“…Regarding mesiobuccal canals of maxillary molars, approximately 2 mm from the apex, root canal wall thickness is set between 0.84 and 2.15 mm, whilst, at an apical distance of about 8 mm, this measure is comprised between 1.23 and 1.58 mm 22 . Correlation among data presented suggests that all groups promoted tolerable canal transportation in most of the samples.…”

Cone beam computed tomography: Adding three dimensions to endodontics

“…CBCT helps in confi rming the presence of MB2 [ Figure 3] and also determining its internal anatomy in relation to mesiobuccal canal. Degerness and Bowles [20] sectioned 150 maxillary molars to study the mesiobuccal root canal anatomy. It was found that 20% of mesiobuccal roots had one canal, 79.8% roots had two canals, and 1.1% had three canals.…”
