Abstract:
Objective:To compare the effect of metal prefabricated crowns and 3M350 universal resin on the dental caries of deciduous teeth.Methods:Retrospective analysis was performed on the clinical data of 89 children with proximal molar caries restoration admitted to Nantong Stomatological Hospital from January 2020 to January 2022. According to treatment methods, they were divided into observation group (metal prefabricated crowns restoration treatment, 49 cases of 49 teeth) and control group (3M350 universal resin restoration treatment, 40 cases of 40 teeth). The repair effect, occlusal function, periodontal index, treatment satisfaction and complications were compared.Results:The success rate of repair in the observation group (93.88%, 46/49) was higher than that in the control group (77.50%, 31/40), and the difference was statistically significant ( P<0.05). The maximum biting force and masticatory efficiency of the two groups after treatment were higher than those before treatment, and the observation group was higher than the control group, and the difference was statistically significant (all P<0.05). Comparison of periodontal indexes between the experimental and control groups comparison of probing depth (PD), plaque index (PLI), and bleeding index (BI) between the two groups before treatment, the differences were not statistically significant (all P>0.05); after treatment, PD, PLI, and BI were lower in both groups, and lower in the experimental group (all P<0.05). The total satisfaction of the observation group (87.76%, 43/49) was higher than that of the control group (65.00%, 26/40), and the difference was statistically significant ( P<0.05). The incidence of complications in the observation group (6.12%, 3/49) was lower than that in the control group (22.50%, 9/40), and the difference was statistically significant ( P<0.05). Conclusions:Compared with 3M350 general purpose resin, metal prefabricated crowns has better repairing effect and lower complication rate on adjacent caries of deciduous teeth, so it can be widely used in clinic.
