目的观察金属烤瓷全冠修复在早期隐裂牙保存活髓临床应用效果。方法选取医院口腔科就诊的早期隐裂牙患者110例,随机分为对照组和观察组,每组55例。对照组采用隐裂牙磨除、脱敏处理等常规治疗方法,观察组采用金属烤瓷全冠修复治疗,观察2组患者治疗6个月、12个月、18个月的临床效果。结果治疗6个月后,观察组总有效率为90.9%,高于对照组的80.0%(P<0.05);治疗12个月后,观察组总有效率为81.8%,高于对照组的65.5%(P<0.05);治疗18个月后,观察组总有效率为76.4%,显著高于对照组的49.1%(P<0.01)。结论早期隐裂牙保存活髓中金属烤瓷全冠修复取得了较好的治疗效果,无论是治疗时还是治疗后的一段时间都能够取得较好的治疗效果,在临床中具有推广和应用价值。
Objective To observe the clinical application of metal porcelain crown restoration in the preservation of vital pulp in early cracked teeth. Methods One hundred and ten patients with early cracked tooth in the hospital were randomly divided into control group and observation group with 55 cases in each group. The control group was treated with occult tear and desensitization treatment. The observation group was treated with metal porcelain crown restoration. The clinical effects of 6 months, 12 months and 18 months in two groups were observed. Results After 6 months of treatment, the total effective rate in the observation group was 90.9%, higher than that in the control group (80.0%, P <0.05). After 12 months of treatment, the total effective rate in the observation group was 81.8%, which was higher than that in the control group % (P <0.05). After 18 months of treatment, the total effective rate in the observation group was 76.4%, significantly higher than that in the control group (49.1%, P <0.01). CONCLUSIONS: The treatment of early PFG with live metal in the preservation of live pulp has achieved a good therapeutic effect. Both the treatment and the treatment after a period of time can achieve better therapeutic effect, which has the value of popularization and application in clinical practice .
