摘　　要：目的:比较全冠修复与调牙合充填治疗早期牙隐裂患儿的效果。方法:选取2019年7月至2020年4月该院收治的162例早期牙隐裂患儿进行前瞻性研究,按照随机数字表法将其分为对照组和观察组各81例。对照组采用调牙合充填治疗,观察组采用全冠修复治疗,两组治疗后均随访1个月。比较两组临床疗效、牙痛程度(Negm分级)、治疗前后最大咬合力、咀嚼效率及并发症发生率。结果:观察组治疗总有效率为96.30%(78/81),高于对照组的85.19%(69/81),差异有统计学意义(P<0.05);观察组Negm分级低于对照组,差异有统计学意义(P<0.05);治疗后1个月,观察组最大咬合力、咀嚼效率均高于对照组,差异有统计学意义(P<0.05);两组并发症发生率比较,差异有统计学意义(P<0.05)。结论:全冠修复治疗早期牙隐裂患儿可提高治疗总有效率,减轻牙痛程度,改善咬合力和咀嚼功能,效果优于调牙合充填治疗。Objective:To compare effects of full crown restoration and occlusal adjustment filling in treatment of children with early cracked teeth.Methods:A prospective study was conducted on 162 children with early cracked teeth admitted to the hospital from July 2019 to April 2020.They were divided into control group and observation group according to the random number table method,81 cases in each.The control group was treated with occlusal adjustment filling,while the observation group was treated with full crown restoration.Both groups were followed up for 1 month after the treatment.The clinical efficacy,the degree of toothache(Negm grade),the maximum bite force,the masticatory efficiency before and after the treatment,and the incidence of complications were compared between the two groups.Results:The total effective rate of treatment in the observation group was 96.30%(78/81),which was higher than 85.19%(69/81)in the control group,and the difference was statistically significant(P<0.05).The Negm grade of the observation group was lower than that of the control group,and the difference was statistically significant(P<0.05).1 month after the treatment,the maximum bite force and the masticatory efficiency of the observation group were higher than those of the control group,and the differences were statistically significant(P<0.05).Further,there was a statistically significant difference in the incidence of complications between the two groups(P<0.05).Conclusions:Full crown restoration in the treatment of the children with early cracked teeth can improve the total effective rate of treatment,reduce the degree of toothache,and improve the bite force and chewing function.Moreover,it is superior to occlusal adjustment filling treatment.
