Purpose: To measure the position of the palatal(P) root tip relative to the buccal(B) root tip and to establish a predictable method for clinicians to locate P root tip during endodontic surgical procedures
N= 50 extracted bifurcated maxillary first premolars
•Each specimen was secured in a soft wax on a stainless steel block •Specimens photographed under 10 magnification and oriented to simulate a clinical view.
•Distance between the root tips were measured using the analySIS Imager 3.2 build 801.
•CBCT scans were used to investigate the BP distance between B and P roots and the MD diameter of P roots at an apico-coronal level
Most highlighted Results:
•In 25 (50%) teeth the P apex was superimposed by the B apex
•In 24 (48%) teeth the P apex was distal to the B apex (1.4 +/- 0.7)
•In 1 tooth the P apex was mesial to the B apex
•In 98% of the specimens, The P apex was positioned palatocoronal or palatocoronodistal to the B apex
