Journal Title: Scholars Journal of Dental Sciences - Year 2015, Vol 2, Issue 7
Abstract
Abstract: The aim of this study was to evaluate clinically the prevalence of radix entomolaris in mandibular first molars in south-eastern population and series of case reports. Methods and materials: 750 mandibular first molars from 406 females and 344 males received tooth canal treatment in Zahedan University of dentistry in 2-years period (2014-2015). The prevalence of a third root revealed by periapical radiographs and the comparison of the occurrence between males and females and between the right and left sides of the mandible were recorded. Statistical Analysis was done using the chi-square test with a significant level set at P < 0.05%. In results of the 750 treated mandibular first molars, 19 teeth were RE with an overall prevalence of 2.5%. There was no significant differences in prevalence of RE between male and female. There was no significant differences in prevalence of RE between right and left sides. In conclusion practitioners must be familiar with all molars variations to reduce failures caused by missing canals and roots.
