【摘要】：目的:评价口腔手术显微镜用于下颌磨牙探查和疏通近中中央根管的临床效果。方法:采集门诊患者126人,下颌磨牙139颗。由3位高年资医生分别在常规肉眼下和口腔手术显微镜下进行下颌磨牙近中中央根管的探查和疏通,比较两者成功率。对下颌磨牙近中中央根管口进行定位测量,并采用偏移投照方法描记该根管走行特点。结果:在显微镜帮助下,所有下颌磨牙近中中央根管的探查和疏通成功率分别提高了11.5%和10.1%。下颌第一磨牙和第二磨牙近中中央根管的疏通率,分别由5.0%增加到15.0%,3.4%增加到了13.6%;而它们的探查成功率分别提高了12.5%和10.2%。所有近中中央根管口均位于髓底发育沟,46.2%靠近近中舌根管口,30.8%在两根管口中间,23.1%靠近近中颊根管口。所有疏通的近中中央根管有45%与近中舌侧根管融合,未发现独立根尖孔类型。结论:在口腔手术显微镜的帮助下,探查和疏通下颌磨牙近中中央根管的数量均有显著提高。
[Abstract]:Objective: to evaluate the clinical effect of dental surgery microscope for probing and dredging proximal central root canal of mandibular molars. Methods: 126 outpatients and 139 mandibular molars were collected. Three senior doctors were used to explore and dredge the proximal central root canal of mandibular molars under conventional naked eye and oral surgery microscope, and the success rates were compared. The proximal central root canal orifice of mandibular molars was measured and the characteristics of the root canals were recorded by offset projection method. Results: with the help of microscope, the success rate of probing and dredging the proximal central root canal of all mandibular molars was increased by 11.5% and 10.1%, respectively. The osseous rate of the first mandibular molar and the second molar increased from 5.0% to 15.0% to 13.6%, respectively, and their successful rate of exploration increased by 12.5% and 10.2%, respectively, in the mandibular first molar and the second molar, in the proximal central root canal of the mandibular first molar and the second molar, and increased from 5.0% to 15.0% and 10.2%, respectively. All the proximal central root canal orifices were located in 46.2% of the developing sulcus of the pulp floor near 30.8% of the proximal tongue root canal orifice and 23.1% near the mesiobuccal root canal orifice between the two canal orifices. 45% of the proximal central canals were fused with the lateral root canals of the proximal tongue, and no independent apical foramen type was found. Conclusion: with the help of oral surgery microscope, the number of probing and clearing the proximal central root canal of mandibular molars is significantly increased.
