261名5～13岁维吾尔族儿童牙龈点彩调查

On gingival stippling of 261 Uyghur children aged between 5 and 13 years old

目的：了解和调查维吾尔族儿童牙龈点彩发生情况。方法采用横断面调查研究方法，调查标准采用 WHO 口腔健康调查基本方法，随机抽取乌鲁木齐市第24小学1～4年级261名维吾尔族学生，其中男生116名，女生145名，进行口腔检查。结果在261名5～13岁儿童中，129名（49．43％）儿童可见牙龈点彩，其中男生55名（42．64％），女生74名（57．36％）。不同性别的学生点彩分布有统计学差异（χ2＝6．460，P ＜0．05），不同年龄段儿童及上、下牙弓牙龈点彩分布差异无统计学意义。结论5～13岁维吾尔族儿童部分发现牙龈点彩。男童点彩发生率低于女童。点彩仍不能作为诊断牙龈和牙周疾病的主要依据，应同时观察牙龈的颜色、外形、厚度、牙周袋深度、探诊出血指数等。

Objective To examine the gingival stippling in Uyghur children and to characterize it.Methods Cross-sectional study was used with the basic method of oral health investigation of WHO.261 Uyghur children （116 boys and 145 girls）were examined with average age of 8.66 years old.Results 49.43% of the children showed stippling,in 42.64% of the boys and 57.36% of the girls.The analysis of the differ-ences between boys and girls in gender （χ2-test）indicates statistical significance （P 〈0.05）.There is no statistical significance between arch,age （χ2-test）with distribution of gingival stippling （P 〈0.05）.Con-clusion Gingival stippling is a normal characteristic of the healthy keratinized gingiva and can be found in children from an age of 5 to 13 years.Boys is lower than girls in stippling incidence.It is not a major crite-rion in clinical assessment of gingival or periodontal inflammation.A better diagnosis on more criteria：col-our,contour,thickness,consistency,pocket depth and bleeding on probing,should be considered as well.
