Morphology of Mesiobuccal Root of Maxilllary First Molars CBCTAnalysis
Objectives:
The aim of this study was to evaluate the anatomy of maxillary first primary molar mesiobuccal canal and its related factors in CBCT images of patients referred to Radiology Department of Islamic Azad University and a private imaging center in Tehran in 1396.
Methods: 80images of computer tomography in individuals aged 17-64 years were used to study mesiobuccal root anatomy in maxillary first molar teeth. Number of roots, root attachment, mesiobuccal root length, root curvature, number and type of canals in mesobuccal root, mesiobuccal first canal distance from mesiobuccal second canal in mm, position of mesiobuccal second canal relative to the corresponding line of mesiobuccal first canal and palatal canal and its distance Compared to this line of mesiobuccal first canal and palatal canal in terms of mm, root concavity location, length and maximum depth at the distal surface of the mesiobuccal root and the minimum thickness of the mesiobuccal root in this area,were examined and finally frequency was reported for qualitative data, and for Quantitative data, mean and standard deviation were reported.
Results: Root attachment was observed in 1.25% of the samples. The mesiobuccal root in the 93.75% of the samples had an extra mesiobuccal canal. mesial to the corresponding line of the mesiobuccal first canal and palatal canal in 83.75% of the samples. In terms of vertucci classification, type II (63.75%), type 1 (6.25%) and type 3 (5%) were the most abundant in maxillary first molar mesiobuccal root. The deepest root concavity zone in the distal wall of the mesiobuccal root was coronal (56.25%), middle (26.25%) and apical (17.50%) zone of the concavity.
Conclusions:
: According to the previous researches and the results obtained from this study, about the frequency of the presence of the second mesiobuccal canal and also the very low root thickness in the distal wall of the first and second mesiobuccal canals due to root deflection in the furca, It is important to carefully search for the additional canal, as well as to prepare and clean it, especially in the furca wall of the mesiobuccal root. In addition, due to the high curvature of the mesiobuccal root, attention to keeping the path and curvature is more necessary during the preparation and shaping of the root canals.
