全冠修复联合根管治疗在牙隐裂伴慢性牙髓炎中的临床疗效分析

Clinical Analysis of Total Crown Prosthesis Combined with Root Canal in Treatment of Dental Fissure with Chronic pulpitis

目的探讨分析全冠修复联合根管治疗在牙隐裂伴慢性牙髓炎中的临床疗效。方法选取2022年2月至2024年4月在如东县中医院口腔科接受治疗的牙隐裂伴慢性牙髓炎患者70例,依据单双号方式随机分为对照组和观察组,各35例。对照组接受根管治疗,观察组接受全冠修复联合根管治疗。术后随访6个月,对比临床疗效、咀嚼功能及咬合力。结果观察组治疗总有效率(97.14%)高于对照组(82.86%),P<0.05。与术前比,术后6个月,两组咀嚼功能及最大咬合接触面、最大咬合力均上升,咬合力不对称指数下降,且术后观察组咀嚼功能及最大咬合接触面、最大咬合力均高于对照组,咬合力不对称指数低于对照组,P<0.05。结论全冠修复联合根管治疗对牙隐裂伴慢性牙髓炎的疗效确切,可提高患者咀嚼功能,增强咬合力。

Objective:To explore and analyze the clinical effect of crown restoration combined with root canal therapy in cracked teeth with chronic pulpitis. Methods:From February 2022 to April 2024,70 cases of cracked teeth with chronic pulpitis were selected and randomly divided into control group and observation group according to odd and even numbers, with 35 cases in each group. The control group received root canal therapy, and the observation group received crown restoration combined with root canal therapy. The patients were followed up for 6 months after operation, and the clinical efficacy、masticatory function and bite force were compared. Results:The total effective rate in the observation group(97.14%)was higher than that in the control group(82.86%),P<0.05. Compared with before operation, 6 months after operation, the masticatory function, the maximum occlusal contact surface and the maximum occlusal force in both groups increased, while the asymmetry index of occlusal force decreased. The masticatory function、the maximum occlusal contact surface and the maximum occlusal force in the observation group were higher than those in the control group, and the asymmetry index of occlusal force was lower than that in the control group, P<0.05. Conclusion:Crown restoration combined with root canal therapy is effective in the treatment of cracked teeth with chronic pulpitis, which can improve the masticatory function and enhance the bite force.
