微创拔牙法与普通拔牙法拔除残根残冠的效果比较

Comparison of minimally invasive and general tooth extraction in pulling out residual roots and crowns

目的对比微创拔牙法与普通拔牙法拔除残根残冠的临床效果。方法选择需拔除的残根残冠600颗,按随机数字表法分为微创组与传统组各30例,分别采用微创拔牙方法与普通拔牙方法拔除残根残冠,观察两组的临床治疗效果。结果微创组在拔牙窝的不完整率、断根率、牙龈撕裂发生率等方面明显优于传统组,差异均有统计学意义(P<0.05)。结论微创拔牙法疗效肯定,值得在临床普遍采用。

Objective To compare the clinical effect of minimally invasive and general tooth extraction in pulling out residual roots and crowns.Methods Six hundred teeth of residual roots and crowns that needed to be extracted were divided into two groups. The minimally invasive tooth extraction and general tooth extraction were applied,respectively.Results The minimally invasive group was obviously superior to the traditional group in rates of incomplete teeth extraction socket,fractured dental root and gum laceration. Conclusion The curative effect of minimally invasive tooth extraction is positive and it should be widely used in clinic.
