Table 3. Depicting the distribution of subjects according to location of canal and their relation with intraoperative nerve exposure. The canal was located lingually in 36 cases and among these 36 patients only 18 were having intraoperative nerve exposure. Out of 75 patients 30 cases were having canal in inter-radicular position and all have nerve exposure intraoperatively. 6 patients out of 75 have canal in inferior position and only 3 have nerve exposure intraoperatively. While no nerve exposure was observed in buccaly located canal.
