Abstract :
Introduction: Knowledge of the internal anatomy and apical foramen of a tooth has always been a
fundamental prerequisite for root canal therapy. Aim of the present study was to evaluate the
distance of apical foramen in relation to the anatomical apex of mandibular molars by cone beam
computed tomography (CBCT) in a selected Iranian population.
Material & Methods: In this cross- sectional study, 97 CBCT images of 25-50 years old
patients were evaluated .the teeth were assessed in coronal plan.
Results: Average (±SD) distance from apical foramen to the anatomical apex in the mesio-buccal
and mesio-lingual, distal canal were [0.938 (±0.294)mm], [0.964 (±0.315)mm] and [0.982
(±0.322)mm] respectively. No statistical difference was found between right and left quadrant.
Conclusion: This study demonstrated that 1mm distance from radiographic apex in mandibular
molars could be appropriate for root canal therapy.
