Frequency of C Shaped Canals in Permanent Mandibular 2nd Molar in Pakistani Population

Abstract

Objective: Evaluation of C-shaped canal frequency and its types in permanent mandibular 2^nd molars in patients presenting with irreversible pulpitis.

Study Design: Cross Sectional study

Place and Duration of Study: This study was conducted at the Operative Dentistry department, Punjab Dental hospital, Lahore from January, 2019 to July, 2019 for a period of six months.

Materials and Methods: 100 patients were examined suffering from irreversible pulpitis, C-shaped canals and its types were assessed using Min’s classification system by using Dental loupes with 3.5 magnification and recorded information. SPSS Version 20 used for entering/analyzing data.

Results: In the 100 individuals, 42% were males and 58% females. 19% according to Min’s classification had a
C-shaped canal in mandibular second molar. Of these, 21% had type-1 (a peninsula), 47.4% had type II (a buccal), and 31.6% had type III (only one mesial) C-shaped canal. The major number was among 16-25 years, 08 (42.1%) but statistically insignificant differences was observed (p-value = 0.138). Similarly, maximum no of C-shaped canal was found among females, 11 (57.9%) but statistically insignificant difference was observed (p-value = 0.992).

Conclusion: There are a significant percentage of C-shaped canals among 2^nd molars mandibular in Pakistani people. Thus treating dentists need to know C-shaped root canal systems their presence as well as configuration so that endodontic treatment success rate increases.
