摘　　要：目的在牙科显微镜下寻找肉眼无法找到的根管。方法选择肉眼无法找到和扩通根管的病例73例,77颗牙齿,在显微镜下寻找根管口。患者年龄分布32～78岁,记录年龄、牙位和寻找结果。结果上颌前牙最常见,下颌双尖牙最少见。未找到根管总数13颗,成功率83.11%。结论钙化、细小根管的发生与牙齿创伤、牙周病密切相关。肉眼无法找到的细小、钙化根管通过显微镜的放大功能,大部分可以找到。但仍有一些根管完全钙化,在显微镜帮助下也无法找到根管口,或找到根管口也无法扩通。Objective To analyze the results of detecting the root canals which cannot be found under naked eyes by using dental microscope.Methods Seventy-seven root canals of seventy-three cases aged 32～78 years old were enrolled,the root canals were not found under naked eyes and were chosen to detect under dental microscope.Location of tooth and results were recorded in detail.Results Sixty-four root canal were found,the succeed rate was 83.11%.The most common calcified or thin root canals were maxillary anterior teeth,while the least teeth were mandible premolars.Conclusion Calcified or thin root canals were related to tooth trauma and periodontal disease.Calcified or thin root canals that cannot be found under naked eye can be found mostly by using dental microscope,but some canals still cannot be found under microscope owing to complete calcification of root canal.
