Clinical effect of all ceramic pre crown restoration method in the treatment of children with extensive dental defects in primary molars
Objective To investigate the clinical effect of all ceramic pre crown restoration method in the treatment of children with extensive dental defects in primary molars.Methods One hundred and forty-eight children with extensive tooth defects in primary molars who were treated at Hangzhou Qingyi Dental Clinic Co.,Ltd.from January 2021 to January 2022 were selected as the study subjects,of which 74 received all ceramic pre crown restoration as the observation group;another 74 cases were treated with direct composite resin filling repair method as the control group.The efficacy at 6 months after repair,the proportions of intact restorations,good adjacency,and close edge fit,as well as the satisfaction score of aesthetic restoration[evaluated using the white esthetic score(WES)and pink esthetic score(PES)],changes in gingival index,plaque index,and chewing function before and 6 months after repair were compared between the two groups.Results In the observation group,the total effective rate 6 months after repair,the proportions of intact restorations,good adjacency and close edge,as well as the WES and PES scores,were significantly higher than the control group(all P＜0.05).There were no statistically significant differences in the gingival index,plaque index,chewing stability,and food-chewing score between the two groups before restoration(all P＞0.05).After 6 months of repair,the gingival index and plaque index were significantly lower than those before repair(all P＜0.05),and the chewing stability and food-chewing score were significantly higher(all P＜0.05),with those in the observation group significantly superior to the control group(all P＜0.05).Conclusion The all ceramic pre crown restoration method has a significant clinical effect on treating children with extensive dental defects in primary molars,which can improve their chewing function.
