Abstract
Objective To explore the effect of preformed metal crown(PMC)repair on occlusal function and repair effect in children with high-risk caries.Methods A total of 120 children with high-risk caries admitted to the author's hospital were enrolled between August 2019 and May 2022.According to random grouping method,they were divided into observation group(n=60)and control group(n=60).The control group was given resin filling,while observation group was given PMC for repair.The clinical curative effect in the two groups was compared.Before treatment,at 1 month and 3 months after treatment,occlusal function(the maximum occlusal contact area,the maximum bite force)was evaluated.At 3 months after treatment,repair effect(dental integrity,restoration condition,edge fitness,secondary caries,wear and adjacency).The occurrence of complications was recorded.Results The difference in total clinical response rate between observation group and control group was not statistically significant(P＞0.05).At 1 month and 3 months after treatment,the maximum occlusal contact area and maximum bite force in observation group were significantly higher than those in control group(P＜0.05).The children with restoration condition,edge fitness,secondary caries,wear and adjacency at grade A in observation group were more than those in control group(P＜0.05),but there was no significant difference in number of cases with dental integrity at grade A between the two groups(P＞0.05).There was no significant difference in the incidence of complications between observation group and control group(P＞0.05).Conclusion The curative effect of the two repair methods is comparable in children with high-risk caries.However,PMC repair has more significant advantages in improving repair effect and occlusal function in children with high-risk caries.关键词
