摘要
Abstract
Objective To investigate the prevalence and treatment of radix entomolaris (RE) in mandibular first molars. Methods 378 cases of mandibular first molars with root canal therapy were collected. Hie case included clinical records and periapieal radiographs of preoperative, intraoperative and postoperative. Hie root number, root canal number and root canal therapy were investigated. Results The RE prevalence of mandibular first molars was 26.98% (102/378). Both gender and bilateral occurrence of RE did not show a significantly difference (P>0.05), but there was a significantly greater incidence of instrument separation, lateral perforation and underfill of the root canals in RE than other canals in mandibular first molars (P<0.05). Conclusion The RE prevalence of mandibular first molar is high and there is a significantly greater incidence of instrument separation, lateral perforation and underfill of the canals in RE than other canals in mandibular first molars.关键词
