    A randomized controlled clinical study of onlay and full crown restorations for early vital cracked teeth

      摘要
    • 摘要:
      目的探讨全瓷高嵌体对早期活髓隐裂牙的2年疗效。
      方法采用随机对照方法研究全瓷高嵌体和全冠对早期活髓隐裂牙修复治疗的2年疗效。选择128例病人128颗患牙，基于临床症状分层，分层一：咬物不适；分层二：咬物不适伴冷热刺激痛。每层患牙按随机数字表法分为高嵌体修复组和全冠修复组。比较2组病人术后24 h疼痛差异；随访2年，分析2种修复方法、临床症状分层对早期活髓隐裂牙的疗效。
      结果分层一与分层二高嵌体组术后疼痛评分均低于全冠组(P < 0.01)。两个分层的高嵌体组和全冠组疗效差异均无统计学意义(P>0.05)。高嵌体组和全冠组均为分层一的治疗有效率高于分层二(P < 0.05)。
      结论全瓷高嵌体治疗早期活髓隐裂牙，术后疼痛反应小，疗效可靠，尽早治疗可提高治疗的有效率。

       

      Abstract:
      ObjectiveTo investigate the 2-year curative effect of full ceramic onlay in the treatment of early vital cracked teeth.
      MethodsA randomized controlled study was conducted to evaluate the 2-year effects of all-ceramic onlay and full crown on the restoration of early vital cracked teeth.One hundred and twenty-eight affected teeth from 128 patients were selected and stratified based on the clinical symptoms, layer one: occlusal discomfort; layer two: occlusal discomfort accompanied by cold and hot irritation and pain.The affected teeth in each layer were divided into the onlay group and full crown group according to the random number table method.The difference of 24 h postoperative pain was compared between two groups.All cases were followed-up for 2 years.The curative effects of the two restoration methods and clinical symptom stratification in the treatment of early vital cracked teeth with living pulp were analyzed.
      ResultsThe postoperative pain scores in onlay group of layer one and two were lower than that in full crown group(P < 0.01).The differences of the effective rate between two groups in layer one and two were not statistically significant(P>0.05).The effective rate of two groups in layer one was higher than that in layer two(P < 0.05).
      ConclusionsThe full ceramic onlay is an effective method in the restoration of early vital cracked teeth, and has little postoperative pain.Early treatment can obviously improve the effective rate of treatment.
