4種不同方法預(yù)防乳磨牙齲病的效果觀察(1)
[摘要]目的 探討4種方法預(yù)防乳磨牙齲病的臨床效果。方法 選取2015年1～6月本轄區(qū)(深圳市寶安區(qū))160例3～5歲幼兒為研究對(duì)象，根據(jù)防齲方法的不同分為四組，每組40例，A組采用含氟牙膏刷牙，B組為含氟牙膏刷牙+涂氟保護(hù)漆，C組為含氟牙膏刷牙+流體樹脂窩溝封閉，D組為含氟牙膏刷牙+流體樹脂窩溝封閉+涂氟保護(hù)漆。分別對(duì)四組幼兒干預(yù)后6、12、18個(gè)月患齲情況進(jìn)行觀察。結(jié)果 A組干預(yù)后6、12、18個(gè)月的乳磨牙齲患率分別為5.00%、15.00%、40.00%，B組干預(yù)后12個(gè)月齲病發(fā)生率為5.00%，干預(yù)后18個(gè)月為25.00%，C組干預(yù)后12個(gè)月齲病發(fā)生率為10.00%，干預(yù)后18個(gè)月為25.00%，D組干預(yù)后18個(gè)月齲病發(fā)生率為10.00%，干預(yù)后18個(gè)月A組齲病發(fā)生率顯著高于B組、C組、D組，D組齲病發(fā)生率最低，差異有統(tǒng)計(jì)學(xué)意義(P<0.05)。鄰面齲發(fā)生率顯示，四組在干預(yù)后6、12個(gè)月時(shí)均無鄰面齲發(fā)生，A組干預(yù)后18個(gè)月時(shí)的鄰面齲發(fā)生率為15.00%，B組與C組均為10.00%，D組無鄰面齲發(fā)生，D組與A組、B組、C組比較，差異有統(tǒng)計(jì)學(xué)意義(P<0.05)。四組干預(yù)后6、12、18個(gè)月的齲均顯示，B組、C組、D組在18個(gè)月時(shí)的齲均明顯低于A組，差異有統(tǒng)計(jì)學(xué)意義(P<0.05)。結(jié)論 單用含氟牙膏刷牙的乳磨牙齲病預(yù)防效果最差，含氟牙膏刷牙+流體樹脂窩溝封閉+涂氟保護(hù)漆的預(yù)防效果最好，氟保護(hù)漆具有保護(hù)窩溝封閉劑作用，也能預(yù)防封閉劑脫落，對(duì)兒童乳磨牙齲病具有顯著預(yù)防作用。

[Abstract]Objective To investigate the clinical effect of 4 different methods for preventing dental caries in deciduous molars.Methods 160 cases of children aged 3-5 years in this district (Baoan District of Shenzhen City) from January to June in 2015 were selected as the research objects and divided into four groups with 40 cases in each group according to the different preventing decay methods.Children in group A used fluoride toothpaste to brush their teeth，children in group B used fluoride toothpaste to brush their teeth and their teeth were coated with fluoride protection paint，children in group C used fluoride toothpaste to brush their teeth and their teeth were coated with liquid resin pit and fissure sealant，children in group D used fluoride toothpaste to brush their teeth and their teeth were coated with fluoride protection paint and liquid resin pit and fissure sealant.The caries status of children in 4 groups 6，12，18 months after intervention were observed.Results In group A，the caries prevalence rates of primary molars was respectively 5.00%，15.00% and 40.00% when 6，12，18 months after intervention，which was 5.00%，25.00% 12，18 months after intervention in group B，with 10.00% 12 months and 25.00% 18 months after intervention in group C，and with 10.00% 18 months after intervention in group D.The incidence of dental caries in group A 18 months after intervention was significantly higher than that of group B，group C or group D，the incidence of dental caries in group D was the lowest and there were statistically significant differences (P<0.05).The incidence of adjacent caries showed that no caries occurred in 4 groups at the end of 6，12 months intervention.The incidence of adjacent caries in group A was 15.00% 18 months after intervention，10.00% in both group B and C and there was no adjacent caries in group D.There was significant differences between group D and group A，group B， group C (P<0.05).The caries showed in 4 groups 6，12，18 months after intervention that the caries in group B，group C or group D 18 months after intervention was significantly lower than that in A group，and the difference was statistically significant (P<0.05).Conclusion The effect of only using toothpaste with fluoride to prevent the deciduous molar caries is the worst and the effect of using fluoride toothpaste brush with fluid resin pit closed and fluoride protective paint is the best.Fluoride varnish has a protective effect of pit and fissure sealant and also can prevent blocking off，which has significant preventive effect on deciduous molar caries.
