生物陶瓷材料iRoot BP Plus在显微根尖手术中应用的疗效分析

Outcome evaluation of bioceramic material as root-end filling materials in endodontic microsurgery

目的评价生物陶瓷材料iRoot BP Plus作为根管倒充填材料在根尖手术中的临床疗效。方法选择临床符合纳入标准的慢性根尖周炎患牙,进行显微根尖手术治疗,对患牙进行根尖切除、超声器械根尖倒预备和iRoot BP Plus根管倒充填。术后1年复查,通过临床检查和X线片评定结果,分析临床疗效。结果 2013年2月至2014年2月期间完成显微根尖外科手术59例,共80颗患牙。术后1年有效回访53例,72颗患牙,术后1年治疗成功率达94.4%(68/72)。患者性别、年龄、牙位、根尖周病变范围大小、根尖周病变类型、有无窦道等因素对疗效的影响均无统计学差异(P>0.05)。结论 iRoot BP Plus作为根尖手术倒充填材料,有良好的临床效果。

Objective To evaluate the outcome of endodontic microsurgery using iRoot BP Plus as root-end filling material in the treatment of chronic apical periodontitis. Methods Fifty-nine patients（ 80 teeth） with chronic apical periodontitis were included and underwent endodontic microsurgery. Surgical treatment included root-end resection,retropreparation with ultrasonic microtips,and root-end filling with iRoot BP Plus. The patients were followed up one year after operation, and the effect was evaluated clinically and radiographically and categorized into complete healing,incomplete healing,uncertain healing and unsatisfactory healing on the basis of clinical and radiographic findings. Results A total of 53 cases（ 72 teeth） were recalled. The overall success rate was 94. 4%. None of the prognostic factors,including age,sex,tooth position,size of periapical radiolucency,biopsy result of periapical lesion and presence of a sinus tract appeared to have any significant effects on the outcome（ P〉 0. 05）. Conclusion iRoot BP Plus is a suitable root-end filling material for endodontic surgery.
