澳门734名幼儿乳牙龋病及龋病活跃性追踪研究

A follow-up study on dental caries of deciduous teeth and caries activity in 734 pre-school children in Macao

目的了解澳门地区幼儿龋病和龋病活跃性的动向表现,分析幼儿龋病的患龋状况。方法选择澳门市2所幼儿园734名2～4岁幼儿追踪1 a,分析其乳牙患龋率、龋均(dft)、龋蚀严重度指数(caries severity index,CSI)和龋病活跃性(caries activity test,CAT)表现与变化。结果历经1 a,734名幼儿患龋率增长11.17%,dft增加0.92±1.49,CSI增加2.98±20.95。2岁组患龋率增加明显高于3,4岁组。734名幼儿CAT,0度明显减少,1度明显增加,2度略有增加,3度略有减少,CAT与1 a前维持一致者仅占36.51%。原1度者中,35.94%转为2,3度,2度者中有53.79%转为1度,3度者中有42.39%、27.17%分别转为2度和1度。结论对幼儿期患龋现状和增长状况应予以重视;幼儿CAT存在加剧和逆转的现象,应探索降低CAT的有效措施,加强预防幼儿龋病的力度。

Objective To investigate the dynamic changing of the dental caries,caries activity and to analyze the dental caries status in pre-school children in Macao.Methods A total of 734 pre-school children aged 2-4 years in two kindergartens were observed for two consecutive years.The performance and change of dental caries prevalence,dft,caries severity index（CSI） and caries activity test（CAT） were analyzed.Results One year later,the prevalence of dental caries increased 11.17%,dft increased 0.92±1.49,CSI increased 2.98±20.95.The increase of dental caries prevalence in 2 years old group was higher than that in 3 and 4 years old groups markedly.As to CAT,degree 0 decreased and degree 1 increased distinctly,degree 2 increased and degree 3 decreased lightly,36.51% maintained the same degree as one year ago,35.94% degree 1 changed to degree 2 or 3,53.59% degree 2 changed to degree 1.About 42.39% and 27.17% degree 3 changed to degree 2 and degree 1 respectively.Conclusion Much attention should be paid on the present status and increasing situation of dental caries.CAT in pre-school children displayed aggravation and converse transformation.The methods to lower CAT should be explored and the prevention of dental caries in pre-school children should be strengthened.
