摘要
目的比较应用流体树脂及渗透树脂对新萌的第二磨牙进行窝沟封闭的效果。方法方便选取2018年1月—2020年6月在该院口腔科就诊的87例患者,共计256颗第二磨牙,分别用流体树脂(A组)和渗透树脂(B组)对其进行窝沟封闭,分别于术后6、12、18、24个月统计窝沟封闭剂保留率及龋病发病率。结果在术后6个月及12个月,A组和B组封闭剂保留率分别为99.22%、100.00%和95.31%、96.09%,差异无统计学意义(χ^(2)=0.000、0.000,P>0.05);而B组和A组龋病发病率分别为0.00%、0.00%和3.13%、2.34%,差异无统计学意义(χ^(2)=0.000、0.000,P>0.05);而在18个月及24个月时,A组和B组封闭剂保留率分别为84.38%、92.97%和79.69%、91.41%,差异有统计学意义(χ^(2)=3.889、6.192,P<0.05);而B组和A组龋病发病率分别为14.84%、6.25%和19.53%、10.16%,差异有统计学意义(χ^(2)=4.140、5.692,P<0.05)。结论渗透树脂由于其颗粒小,渗透性及流动性强,可以获得更好地封闭效果及防龋效果,并可有效治疗早期龋以及辅助冷光美白技术改善氟斑牙。
Objective To compare the effect of fluid resin and penetrating resin on the pit and fissure sealing of the new second molars.Methods It is convenient to select 256 second molars were treated with 87 patients in the Department of Stomatology from January 2018 to June 2020.The pits and fissures were sealed with fluid resin(Group A)and penetrating resin(Group B),respectively.The retention rate of pit and fissure sealant and the incidence of dental caries were counted at 6,12,18,and 24 months.Results The retention rates of the Group A and Group B of sealants were respectively at 6 months and 12 months after surgery 99.22%,100.00%and 95.31%,96.09%,the difference was not statistically significant(χ^(2)=0.000,0.000,P>0.05);and the incidence of dental caries in the Group B and Group A was 0.00%,0.00%and 3.13%,2.34%,the difference was not statistically significant(χ^(2)=0.000,0.000,P>0.05);and at 18 months and 24 months,the retention rates of the Group A and Group B of blocking agents were 84.38%,92.97%and 79.69%,91.41%,the difference was statistically significant(χ^(2)=3.889,6.192,P<0.05);and the incidence of dental caries in the Group B and Group A was 14.84%,6.25%and 19.53%,10.16%,the difference was statistically significant(χ^(2)=4.140,5.692,P<0.05).Conclusion Due to its small particles,strong permeability and fluidity,penetrating resin can obtain better sealing effect and anti-caries effect,and can effectively treat early caries and assist cold light whitening technology to improve dental fluorosis.
