Racial predilection of C-shaped canal configuration in the mandibular second molar

Abstract

AIM: The purpose of this article is to determine the racial predilection of C-shaped canal configuration in a mandibular second molar. BACKGROUND: Unusual root canal anatomy always poses a diagnostic and treatment challenge. Identification of such variation is important for the success of root canal treatment outcome. C-shaped canal configuration is such an aberrant morphology of molar teeth that vary in different population and is commonly seen in a mandibular second molar. Thus, knowledge of racial predilection of C-shaped canal configuration in different population for early diagnosis is obligatory. MATERIALS AND METHODS: < 0.05 was performed to assess the statistical significance of this anomalous anatomic variation among the different population. RESULTS: Statistical test revealed a significant variation between the Asian and nonAsian population. The highest incidence of racial predilection was observed in China (Asia) with 93.1%, and the minimum was observed in America with 2.7%. CONCLUSION: This research reported that racial predilection of C-shaped canal configuration in mandibular second molar varies significantly.
