目的探讨分析不同拔牙方法对拔除残根残冠的临床效果。方法选取需行残根残冠拔除的患者72例,随机分成A、B两组,各36例,A组采用微创拔牙方法、B组采用普通拔牙方法,比较治疗效果。结果 A组拔牙时间较B组短,疼痛评分较B组低,满意度评分高于B组,差异均显著(P<0.05);A组在前牙、双尖牙、磨牙的术后拔牙窝的不完整率、断根率、牙龈撕裂发生率方面均明显优于B组(P<0.05)。结论微创拔牙方法能显著提高拔牙窝的完整率,降低断根、牙龈撕裂的发生,减轻拔牙痛苦,提高患者满意度,值得推广和使用。
Objective To investigate the clinical effects of different extraction methods on remnant crown. Methods Totally 72 patients with residual crown removal were randomly divided into A group and B group, 36 cases in each group. A group was treated by minimally invasive extraction and B group was treated by ordinary extraction. The treatment effect was compared. Results The tooth extraction time in group A was shorter than that in group B, the pain score was lower than that in group B, and the satisfaction score was higher than that in group B (P <0.05). In group A, The incomplete rate, the root breakage rate and the incidence of gums were significantly better than those in group B (P <0.05). Conclusion The minimally invasive extraction method can significantly improve the complete rate of tooth extraction socket, reduce the incidence of root rupture and gums tear, alleviate the pain of tooth extraction and improve patient satisfaction, which is worthy of promotion and use.
