目的：研究云南省第一人民医院患者下颌第2恒磨牙C型根管的发生率并比较其一次性或两次性根管治疗的成功率。方法选取本院口腔内科就诊患者260例下颌第2恒磨牙，X线牙片和临床检查分析C型根管及各型发生率；C型根管患牙随机分为A、B2组，分别进行一次性和两次性根管治疗，6个月后比较2组成功率。结果260例中有80例为C型根管，发生率为30.77%；术前X线检查发现2组患牙共有Ⅰ型25例（31.25%），Ⅱ型32例（40%），Ⅲ型23例（28.75%）；改良Melton分类法发现C1型17例（21.25%）、C2型39例（48.75%）、C3a型13例（16.25%）、C3b型11例（13.75%），C4型0例；术后6个月A组成功率为78.94%（30/38），B组成功率为81.08%（30/37），2组间差异无统计学意义（P>0.05）。结论我院患者下颌第2恒磨牙C型根管较常见，一次性根管治疗可用于下颌第2恒磨牙C型根管系统。
目的：研究雲南省第一人民醫院患者下頜第2恆磨牙C型根管的髮生率併比較其一次性或兩次性根管治療的成功率。方法選取本院口腔內科就診患者260例下頜第2恆磨牙，X線牙片和臨床檢查分析C型根管及各型髮生率；C型根管患牙隨機分為A、B2組，分彆進行一次性和兩次性根管治療，6箇月後比較2組成功率。結果260例中有80例為C型根管，髮生率為30.77%；術前X線檢查髮現2組患牙共有Ⅰ型25例（31.25%），Ⅱ型32例（40%），Ⅲ型23例（28.75%）；改良Melton分類法髮現C1型17例（21.25%）、C2型39例（48.75%）、C3a型13例（16.25%）、C3b型11例（13.75%），C4型0例；術後6箇月A組成功率為78.94%（30/38），B組成功率為81.08%（30/37），2組間差異無統計學意義（P>0.05）。結論我院患者下頜第2恆磨牙C型根管較常見，一次性根管治療可用于下頜第2恆磨牙C型根管繫統。

Objective To investigate the incidence of C-shaped root canal systems in mandibular second perma?nent molar of patients in the First People’s Hospital of Yunnan Province, and compare the success rate between one-and two-visit root canal treatment. Methods Two hundred and sixty mandibular second molars were recruited from the pa?tients in the department of endodontics of our hospital, and teeth with C-shaped root canal were categorized by using radio?graphic classification criteria and the modified Melton’s method. Teeth with C-shaped root canal systems were then random?ly divided into two groups to receive one-or two-visit root canal treatment, and success rates of 6-month post-operation were compared between two groups. Results Eighty out of 260 mandibular second molars exhibited C-shaped canals (30.77%). Radiographic examination showed that 25 teeth belonged to typeⅠ(31.25%), 32 teeth typeⅡ(40.00%) and 23 teeth typeⅢ(28.75%) in two groups. As for modified Melton’s method, the incidence rates were 21.25%, 48.75%, 16.25%and 13.75% for C1,C2,C3a and C3b, respectively, while C4 was not found. The success rates were 78.94% (30/38) and 81.08%(30/37) for A group and B group, respectively, with no statistically significant difference between two groups ( 78.94 vs 81.08, P>0.05). Conclusion Results indicate a frequent incidence of C-shaped root canal system of mandibular per?manent second molars in our hospital. One-visit root canal treatment is an effective way for treating C-shaped canals in man?dibular permanent second molar.
