摘要
目的回顾性分析实施根尖切除术的患牙是否应用羟基磷灰石生物陶瓷填充骨缺损区对临床疗效的影响。方法对2018—2020年在我科进行根尖切除术的病例进行回顾性分析,按照接受根尖切除术患者的年龄、性别、患牙牙位、根尖周病变范围、临床病因类型分组,通过术前和术后6个月回访的临床症状转归以及影像学检查,对比术中采用羟基磷灰石生物陶瓷充填骨缺损+口腔修复膜覆盖和骨缺损区单纯覆盖口腔修复膜两种方法的临床成功率。结果经纳入和排除标准,共筛选有效回访病例57例(男23例,女34例),共计88颗患牙,治疗成功率为97.7%;根据统计分析结果,患者性别、年龄、牙位、根尖周阴影大小以及临床病因类型对根尖切除术疗效无统计学影响(P>0.05),但是否使用羟基磷灰石生物陶瓷充填骨缺损区对疗效有显著性影响(P<0.01),且使用羟基磷灰石生物陶瓷与其他因素间不存在交互作用(P>0.05)。结论对于根尖病变范围小于7 mm的病例,骨缺损区单纯覆盖口腔修复膜即能够达到较满意的治疗效果;对于病变大于7 mm的患牙,应使用生物陶瓷充填骨缺损区。
Objective To retrospectively analyze the effect of using hydroxyapatite bioceramics to fill the bone defect in the affected teeth after apicectomy.Methods Retrospective analysis was conducted on the cases receiving apicectomy in our department from 2018 to 2020,and the patients were grouped according to their age,gender,affected tooth position,periapical lesion range,and clinical etiology type.Clinical symptoms and imaging examinations were conducted by preoperative and 6-month follow-up visits.The clinical success rates of the two methods of intraoperative filling of bone defect with hydroxyapatite bioceramics and covering bone defect area with oral repair membrane were compared with that of only covering bone defect area with oral repair membrane.Results By the criteria of inclusion and exclusion,a total of 57 effective follow-up cases(23 males,34 females)with 88 affected teeth were screened and included,and the treatment success rate was 97.7%.According to the results of statistical analysis,gender,age,tooth position,periapical shadow size and clinical etiology type of patients had no statistical influence on the efficacy of apicectomy(P>0.05),but whether hydroxyapatite bioceramics was used to fill the bone defect area had a significant influence on the efficacy(P<0.01).There was no interaction between the use of hydroxyapatite bioceramics and other factors(P>0.05).Conclusion For cases with apical lesions less than 7 mm,a satisfactory treatment effect can be achieved if the bone defect area is simply covered with oral repair membrane.For teeth with lesions greater than 7 mm,bioceramics should be used to fill the bone defect area.
