ABSTRACT
The aim of this study was to observed the anesthetic efficacy of the alveolar
nerve block on nine patients that CBCT diagnosed unilateral retromolar canal on a
double-blind, split-mouth approach. The assessments of patient response to thermal
(pulp vitality test) and pressure (compression of soft tissue) stimuli were carried out
before and 5 minutes after the inferior alveolar nerve block procedure, using both
visual analog scale (VAS) and Mc Gill pain questionnaires (McG). The mean percentage
of patient response decreased after alveolar nerve block, according to both VAS and
McG, and was statistically similar among hemi mandibles with and without retromolar
canal (Wilcoxon›0.05); however, those without retromolar canal presented greater
reduction in patient response in 6 out of 9 cases. Therefore, the retromolar canal is
not a determinant factor of inferior alveolar nerve block failure.
