Pak Oral Dental J Jan ;40(4):240-3.

The study was carried out to assess various root canal configurations in permanent mandibular incisors of Pakistani population using Cone Beam Computerised Tomography scan. A descriptive retrospective study was planned by using CBCT images of past 01 year, i.e. December 2017 till November 2018. Approval was taken from ethical review committee. Images were assessed for different root canal configurations in permanent mandibular incisors using software NNTVIEWER NewTOM. Data was entered and analyzed using SPSS 20. Total number of 268 mandibular incisors of 67 patients were studied. 64.2% of the images were of male patients while 35.8% were of females. Mean age of the patients was 48.1 +- 15.9 years. All incisors were single rooted. Root configuration of type III was found in 29.9% of central incisors and 34.3% of lateral incisors. The rest of root canals of both central and lateral incisors were of type I. Frequency of occurrence of different root canal configurations were significantly different in central and lateral incisors (p< 0.001). All mandibular incisors were single rooted but 35.82% of the patients had more than one root canal in at least one of the mandibular incisors.
