Abstract Objective To investigate the effect of resin filling and metal precrown on dental caries in children's deciduous teeth. Methods According to random number table method,78 children who underwent molar dental caries were divided into reference group and study group.Selected 39 patients in each group were included.The reference group underwent traditional resin-filled restoration,and the study group underwent metal precrown restoration.The repair effect,occlusal ability,masticatory efficiency and complications were compared between the two groups. Results The excellent repair rate of the study group was,which was higher than that of the reference group,with statistical difference(P<0.05).There was no significant difference in occlusal ability and masticatory efficiency between the two groups before repair(P>0.05).The maximum occlusal area,masticatory efficiency and masticatory force of the two groups were higher than those before repair 6 months after repair,while the maximum occlusal area of the study group was mm2,the maximum occlusal force was Ibs and the masticatory efficiency was.Higher than in the reference group,there were statistical differences(P<0.05).The complication rate of the study group was lower than that of the reference group(P<0.05).The incidence of post-repair complications in the study group,which was lower than that in the reference group,with statistical difference(P<0.05). Conclusion The high success rate of metal precrown restoration for deciduous molar proximal caries can effectively improve the occlusal ability of children,help children chew food more efficiently,effectively improve chewing efficiency,and significantly reduce the incidence of complications such as restoration loosening,loss and secondary caries,which has high application value in the treatment of children oral diseases.
