目的观察微创与传统拔牙技术在阻生齿拔除中的应用效果。方法 90例阻生齿患者,以随机数字表法分为观察组与对照组,各45例。对照组实施传统的拔牙技术,观察组应用微创拔牙技术,对比两组效果。结果对照组手术时间长于观察组,且拔牙恐惧程度、拔牙窝不完整程度和术后肿胀评分均明显高于观察组,两组比较差异均具有统计学意义(P<0.05)。观察组中有2例患者出现断根,断根率为4.4%,对照中有9例患者出现断根,断根率为20.0%,两组比较差异具有统计学意义(χ2=5.075,P<0.05)。结论微创技术拔除阻生齿具有操作简单、创伤小的优点,可作为拔除阻生齿的首选方案。
Objective To observe the effect of minimally invasive and conventional extraction techniques in the removal of impacted teeth. Methods Totally 90 patients with impacted teeth were randomly divided into observation group and control group with 45 cases in each group. In the control group, the traditional extraction technique was used. The observation group was treated with minimally invasive extraction technique, and the two groups were compared. Results The operation time of the control group was longer than that of the observation group, and the degree of extraction fear, the incomplete degree of extraction socket and the postoperative swelling score were significantly higher than those in the observation group. There was significant difference between the two groups (P <0.05). In the observation group, there were 2 cases with broken roots, with the rate of cut-off being 4.4%. There were 9 cases with broken roots and 20.0% of broken roots in the control group. There was significant difference between the two groups (χ2 = 5.075, P <0.05). Conclusion Minimally invasive extraction of impacted teeth with simple operation, the advantages of small trauma can be used as the removal of impacted teeth preferred program.
