摘要
目的：了解包头市3~5岁儿童患龋情况。方法：按照第三次全国口腔健康流行病学调查标准,采用整群抽样方法,随机抽取包头市区21所幼儿园3~5岁共2 976名儿童进行龋病检查,并对所得资料进行统计学分析。结果：包头市3~5岁儿童乳牙患龋率65.726%,龋均5.482±3.424,龋损充填率2.340%;男、女患龋率和龋均无统计学差异（P〉0.05）;不同年龄患龋率比较,4岁（69.753%）、5岁（71.631%）均高于3岁（58.031%）（P〈0.05）,而4、5岁间无统计学差异（P〉0.05）;龋均相比,5岁（6.418±3.127）高于3岁（4.748±3.282）和4岁（5.348±3.646）（P〈0.05）,而3、4岁间无统计学差异（P〉0.05）;男童患龋病严重程度大于女童（P〈0.05）;不同年龄与患龋相关（P〈0.05,CP=0.165）;下颌第二乳磨牙患龋率最高,下颌乳中切牙患龋率最低（P〈0.05）,患龋率最高为牙合面,舌、腭面最低（P〈0.05）。结论：包头市区3~5岁儿童龋病患病率较高,龋损充填率低。
AIM： To investigate the dental caries prevalence in 3-5 years old children in Baotou City.METHODS： According to the Third National Oral Health Epidemiological Survey Unified Standard,2,976 children aged 3- 5 years were randomly selected from 21 kindergartens. Dental decay was examined with the method of cluster sampling. Data were statistically analyzed. RESUITS： The prevalence of caries, dmf, caries filling rate were65. 726%,5. 482 ± 3. 424 and 2. 340%,respectively. The percentage of caries and dmf in male（ 65. 432% and5. 669 ± 3. 519） were not significantly different from those of the females（ 66. 008% and 5. 169 ± 3. 346）（ P 0. 05）.The caries percentage of 4- year- old（ 69. 753%） and 5- year- old（ 71. 631%） groups were significantly higher than that of 3- year- old group（ 58. 031%）（ P 0. 05）,but there was no statistical difference between 4 and 5-year- old groups（ P 0. 05）. The dmf of 5- year- old group（ 6. 418 ± 3. 127） was higher than that of 4- year- old（ 5. 348 ± 3. 646） and 3- year- old groups（ 4. 748 ± 3. 282） respectively（ P 0. 05）,there was no significant difference between 3 and 4- year- old groups（ P 0. 05）. The caries was more severe in males than in females（ P 0. 05）. Age was correlated with the risk of caries severity（ P 0. 05,CP = 0. 165）. Mandibular second deciduous molar was with the highest rate of caries and mandibular incisor was with the lowest（ P 0. 05）. Tooth occlusal surface was with the highest rate of caries and the tongue palatal surfaces the lowest（ P 0. 05）. CONCLUSION：There are a high prevalence of dental caries and low caries filling in 3- 5- year- old children in Baotou.
