Caption: Figure 2: Long axis of the lower first molar was constructed by joining the apex of mesiobuccal root
with mesiobuccal cusp.
Three-dimensional analysis of maxillary first molar mesiobuccal root
canal configuration and curvature using micro-computed tomography.
All roots (palatal and distobuccal) were observed to contain one root canal (100%) except the mesiobuccal root
where single root canal was observed in 29.6% of maxillary molars (Table-I).
The occurrence of a third canal in the mesiobuccal root
of maxillary first molar was first reported by Acosta Vigouroux & Trugeda Bosaans (1978).
Anatomic Determination of the Mesiobuccal Root
Resection Level in Maxillary Molars.
As an example, it is more relevant to report that complex canal morphology in the distobuccal root of a maxillary first molar corresponds to complex canal morphology in the mesiobuccal root
than reporting the complexity of both in a separate code as with the Vertucci classification.
The mesiobuccal roots
were considered in the MX group and the mesial roots in the MD group.
Besides the high incidence and difficulties in locating the MB2 canal, there is considerable variation in the configuration of the canal system in the mesiobuccal root
of maxillary first molars (Verma & Love; Yamada et al.; Gilles & Reader; Grande et al.; Kulild & Peters; Spagnuolo et al.; Weine et al.).
(MBR) of maxillary molars is the most complex root in entire dentition.
Only roots with radiographic confirmation of Vertucci's type IV root canal configuration in the mesiobuccal root
Morphology of Mesiobuccal Root
Canals of Maxillary First Molars: a comparison of CBCT scanning and Cross-sectioning.
Given the anatomical complexity of the mesiobuccal root
and the high frequency of the MB2 canal, the clinician must assume the existence of two canals in this root, and CBCT scanning is a good way to initially identify the MB2 canal in the different root thirds.
Most of cases in this report were maxillary incisors (n=10) or mesiobuccal roots
of maxillary molars (n=5).
In SRME group, the changes during the total treatment period (T2-T0) were analyzed on the axial sections of the CT images and significant decreases in the BABT of tooth number 16 (level of the distobuccal and mesiobuccal roots
), and significant increases in the palatal bone thickness of the same tooth were found (p<0.0125).
