Abstract:
Objective:To investigate the root canal anatomy of one-rooted mandibular second molars. Methods:The root canals of 18 one-rooted mandibular second molars were visualized on radiographs and clinical examination, some specimens were cut at the mid-root level and observations were made on the coronal root section. Teeth with C-shaped canal system were categorized by using a modification of Melton classification.Results:12 molars exhibited C-shaped canals.2 molars were classified as category Ⅰ,5 as Ⅱ and another 5 cases as Ⅲ.Conclusions:C-shaped canals in mandibular second molars vary in canal number and shape.
