摘要
目的探讨显微超声技术在在治疗上颌第一恒磨牙近颊根管的应用。方法以112颗上颌第一恒磨牙为研究对象,开髓后探查近颊第二根管(second mesiobuccal root canal,MB2),未能发现MB2者在牙科手术显微镜下(dental operating microscope,DOM)采用超声技术探查MB2根管口。结果上颌第一恒磨牙近颊第二根管肉眼下探查发现率为32.1%,使用显微镜后MB2的发现率为75.9%。结论显微超声技术有助于发现较隐匿的MB2根管口,对于完善根管治疗具有较大临床意义。
Objective To observe the effect of the dental operating microscope（DOM） and the ultrasonic instruments in the treatment of the mesiobuccal root canal of the maxillary first permanent molar.Methods The pulp chambers were opened and the second mesiobuccal root canals（MB2） were explored in 112 maxillary first permanent molar.MB2,not found under naked eyes,was explored with DOM and ultrasonic technique.Results The detection rate of MB2 with naked eyes was 32.1%.The rate was 75.9% by using DOM and ultrasonic instruments.Conclusions It is helpful to find some invisible orifice of MB2 using DOM and ultrasonic technique,and it would be beneficial to improve the root canal therapy.
