目的比较纤维桩与铸造金属桩核修复大面积牙体缺损的疗效。方法将大面积牙体缺损的患者140例随机分为研究组和对照组各70例。研究组接受纤维桩修复,对照组接受铸造金属桩核修复,对2组患者进行随访2年,观察2组的成功率、治疗疗效。比较2组治疗不同时间牙周探诊深度及碱性磷酸酶。结果研究组成功率为97.14%(68/70)高于对照组的85.71%(60/70),差异有统计学意义(P<0.05)。2组患者进行随访2年,研究组的桩核松动、桩核折断、根折、牙龈炎症、根尖周炎的发生率低于对照组,差异均有统计学意义(P<0.05)。2组治疗前牙周探诊深度、碱性磷酸酶比较无显著差异(P>0.05)。2组治疗后1年、2年牙周探诊深度、碱性磷酸酶均升高,但研究组低于对照组,差异有统计学意义(P<0.05)。结论与铸造金属桩核修复大面积牙体缺损相比,纤维桩疗效更为肯定,通过术后长期随访发现纤维桩质量后桩核松动、桩核折断、根折、牙龈炎症、根尖周炎发生率更低。
Objective To compare the efficacy of fiber post and cast metal post to repair large area dental defects. Methods A total of 140 patients with large-scale dental defects were randomly divided into study group (70 cases) and control group (70 cases). The study group received fiber post repair, the control group received cast metal post repair, the two groups were followed up for 2 years, the success rate was observed in two groups, the curative effect. The depth of tooth exploration and alkaline phosphatase in the two groups were compared. Results The success rate of the study group was 97.14% (68/70), which was significantly higher than that of the control group (85.71%, 60/70) (P <0.05). The 2 groups of patients were followed up for 2 years. The study group had a statistically significant (P <0.05) difference of post-core stump looseness, broken post-core, root fracture, gingival inflammation and apical periodontitis. There was no significant difference in alkaline phosphatase between the two groups (P> 0.05). After 1 year and 2 years of treatment, the probing depth of periodontal exploration and alkaline phosphatase increased in both groups, but the research group was lower than the control group, the difference was statistically significant (P <0.05). Conclusion Compared with casting metal post to repair large-area dental defects, the effect of fiber post is more certain. After long-term postoperative follow-up, post-core looseness, post-core fracture, root fracture, gingival inflammation, apical periodontitis The incidence is lower.
