“Anatomic Relationship Of Mandibular Canal Using Cone Beam Computed Tomography,”

Abstract

Introduction – The morphometric parameters of the mandibular canal (MC) may vary depending on the
population studied. Therefore, clinical data are required. The MC's specific location must know to plan and
advise various dental treatments. This study aimed to measure the distance of the root of mandibular teeth to
the mandibular canal & diameter of mandibular canal.
Material and Methods -CBCT scans of 200 subjects in age group of 18–60-year were evaluated. The distance
of the roots of lower jaw teeth from the upper margin of the Mandibular Canal was measured in the crosssection & for diameter of mandibular canal inner maximum vertical and horizontal diameters were measured
in coronal plane. Statistical analysis was performed in SPSS (VERSION 20.0)
Results – For the observations, paired t-test was applied to compare the right & the left side. Mandibular Canal
was found to be in close relationship with the roots of the third molar, premolar, second molar and first molar
respectively with a mean distance of 1.732, 2.743 mm, 3.254 mm, and 3.936 mm, respectively. Mandibular
canal diameter the mean vertical and horizontal diameter of the MC was found to be 2.436 mm and 2.231mm,
Conclusion - it is critical to the clinician to know three-dimensionally the topographic relationships between
the inferior teeth roots and the mandibular canal before proceeding to any invasive dental or surgical procedure
at this region.
