摘要
目的:比较不同修复方式对乳磨牙龋病治疗的临床疗效。方法:选取在2016年4月~2018年3月于我院需行乳磨牙龋齿修复治疗的患儿91例,共168颗患牙,随机数字表法分为复合树脂充填组55颗,传统预成冠治疗组56颗,Hall技术治疗组57颗;随访6个月、12个月、24个月,观察远期临床疗效并分析失败的原因。结果:龋坏的乳磨牙修复治疗6个月及12个月时,直接树脂充填修复与传统金属预成冠组、Hall技术组成功率差异均无统计学意义(P> 0. 05)。24个月时,传统金属预成冠组及hall技术组成功率均明显高于直接树脂充填(P <0. 05),但hall技术和传统金属预成冠修复成功率差异无统计学意义(P> 0. 05)。结论:治疗乳磨牙龋坏,hall技术和传统的金属预成冠修复成功率高于直接树脂充填,而hall技术和传统的预成冠修复均有利于龋损的修复,但hall技术更优。
Objective: To compare the long-term clinical effects of different restoration methods on deciduous molar caries. Methods: A total of 91 children( 168 teeth) with dental caries were selected,that divided into composite resin filling groups with 55 patients group,the traditional pretreated crown group with 56 patients and 57 patients in the Hall treatment group. With 6,12 and 24 months follow-up were observed,and the long-term clinical efficacy was observed and the reason of the failure was analyzed. Results: There was no significant difference in the successful rate among the resin filling,the traditional metal preformed crown group and the Hall technique group for 6 months and 12 months( P > 0. 05). Up to 24 months,the success rate of the traditional metal preformed crown group and the Hall technique group was significantly higher than that of the direct resin filling( P < 0. 05),but the Hall technique group and the traditional metal preformed crown group were found that the success rate was not statistically different( P > 0. 05). Finally,the reasons for failure of repair were analyzed.Conclusion: The treatment of decayed tooth decay,the success rate of Hall technique and traditional metal preformed crown restoration is higher than that of resin filling,while Hall technique and traditional preformed crown restoration are beneficial to the repair of caries,but the Hall technique is better.
