铸瓷髓腔固位冠修复应用于牙根管治疗后的临床效果评价

Evaluation of clinical effect of porcelain fused for metal crown restoration after root canal therapy

目的:探讨铸瓷髓腔固位冠修复在牙根管治疗后的临床效果。方法:选取某院2013年12月至2015年12月收治的90例根尖周炎或牙髓炎患者的临床资料进行分析,患者均接受牙根管治疗,依据修复方式将其分为观察组(采取铸瓷髓腔固位冠修复)与参照组(采取铸瓷全冠修复),每组各为45例。比较2组患者患牙经治疗后,3个月、6个月、1 a修复体的完整性、密合性、残留率、牙龈和食物嵌塞情况、颜色变化。结果:观察组患者3个月、6个月、1 a修复体边缘密合性、完整性均明显高于参照组(P<0.05)。2组患者修复牙齿在残留率、牙龈和食物嵌塞情况、颜色变化比较均有显著差异(P<0.05)。结论:在牙根管治疗术后给予患者铸瓷髓腔固位冠修复,1 a内其患牙边缘密合性、完整性、松动或脱落、牙龈情况和食物嵌塞、颜色情况均优于采取铸瓷全冠修复,修复体的修复效果令人满意,能够满足临床需求,其远期效果尚需进一步观察研究。

Objective To investigate the clinical effect of porcelain fused for metal crown restoration after root canal therapy.Methods Totally 90 patients with pulpitis or periapical periodontitis from December 2013 to December 2015 had their clinical data analyzed, who underwent root canal therapy and were divided equally into an observation group and a control group. The observation group took porcelain endocrowns repair and the control group applied ceramic crown. The two groups were compared on the restoration integrity, edge sealing, residual rate, gum, food impaction and color 3 months, 6 months and 1 a after treatment. Results The observation group behaved significantly better than the control group in the edge sealing and restoration integrity（P 0.05）. There were significant differences between the residual rates, gum and food impaction in the two groups（P0.05）. Conclusion Porcelain endocrowns repair gains advantages over ceramic crown repair in edge sealing,integrity, gum, food impaction and color after root canal therapy, though its long-term effect needs further investigation.
