Preliminary investigation to achieve patency of MB2 canal in maxillary molars

Abstract
Aim: To establish a preliminary investigation about the possibility to achieve patency of second
mesiobuccal canal (MB2) in mesiobuccal roots of maxillary molars. Methods: Three hundred
and five first maxillary molars were examined with direct vision and with magnification. The root
canal configurations were classified according to the possibility to achieve patency in MB2
canals. Clearing technique was also performed to illustrate root canal anatomy and verify the
presence of extra canals not identified with magnification. Results: The prevalence of MB2
canals detected only with direct vision was 53.4% and the use of the surgical operating microscope
increased rate detection to 90.7%. The clearing technique revealed the presence of MB2 canal
in 12 more teeth (94.7%). In 49.1% of the localized MB2 canals, it was not possible to achieve
patency. Conclusions: The findings of the presented study revealed that it was only possible
to achieve patency in 50.9% of the MB2 canals, showing that achieve patency in the MB2 canal
is much more challenging than locating them.
Keywords
