摘要
目的采用锥形束CT观察分析广州地区人群下颌前牙的根管系统。方法选取2015年4月~2016年7月之间我院拍摄的1038颗下颌前牙的CBCT图像扫描数据进行分析,对所有患者下颌前牙根管的数目、构型、对称性和根尖孔偏移等情况进行分析统计。结果广州地区人群下颌前牙的根管类型以Ⅰ型为主,比例为87.38%,其次为Ⅲ型比例为9.73%,Ⅱ型根管为2.50%,Ⅴ型根管最少,仅为0.39%。下颌前牙两侧同为单根管的发生率最高,而两侧同为双根管则侧切牙发生率较高。下颌前牙有32.5%的主根尖孔偏向唇侧,仅2.51%的主根尖孔开口偏舌侧。结论广州地区人群下颌前牙双根管发生率较高,根尖孔唇侧偏移较常见,锥形束CT能进行有效地诊断。
Objective The root canal system of mandibular anterior teeth in guangzhou was observed and analyzed by conical beam CT.Methods The CBCT scan data of 1038 mandibular anterior teeth taken by our hospital from April 2015 to July 2016 were selected for analysis,The number,configuration,symmetry and apical hole deviation of the mandibular anterior root canal were analyzed and counted in all patients.Results Guangzhou the root canal of mandibular anterior teeth in the type is given priority to withⅠtype,Compared with 87.38%,Followed byⅢtype was 9.73%,Ⅱtype root canal was 2.50%,LeastⅤtype root canal,Only 0.39%.The incidence of single tube on both sides of mandibular anterior teeth was the highest,The incidences of lateral incisions were higher with double root canals on both sides.The mandibular anterior teeth had 32.5%of the primary apical foramen to the lip,Only 2.51%of the main root apical orifice has an opening on the lingual side.Conclusion The incidence of mandibular anterior teeth double root canal is high in guangzhou area,Lip deviation of apical foramen is more common,Conical beam CT can diagnose effectively.
