下颌侧切牙双根管的研究现状

摘要

下颌侧切牙多为单根管,但临床工作中发现下颌侧切牙双根管甚至多根管也较常见.目前国内外关于下颌侧切牙双根管的病例报道较多,本文就1971~2016年国内外报道的下颌侧切牙双根管的发生率、根管形态分型及检出方法作一综述.%Mandibular lateral incisors mostly have one single root canal,but during the clinical work double root canals or even more root canals are frequently found. The early recognition of these configurations facilitates clean-ing,shaping and filling of the root canal system. Now,there are many case reports about the mandibular incisors with double root canals at home and abroad. This article reviews all available germane articles of the past 45 years(from 1971 to 2016) from the following aspects:the incidence,the types and detection of the double root canals of the man-dibular lateral incisors.
