膳食营养对小学生氟斑牙发病程度的影响

Objective To investigate the effect of dietary nutrition on dental fluorosis degrees of school children in endemic fluorosis areas. Methods Two hundred and eight children aged 8 to 12 years were chosen using cluster random sampling method from a village of municipal suburban and a town of autonomous region, both with a history of serious endemic fluorosis. Morning urinary fluoride was measured by fluoride ion electrode. The Tooth Surface Index of Dean was applied to measure the severity of dental fluorosis. Food and nutrient intakes were analyzed according to the 3-day diet records and duplicate meals. Results The urinary fluoride concentration of the children in the town [(6.80±3.90)mg/L]was much higher than those in the village [(5.20±2.75)mg/L, t= 3.21, P < 0.01]. Dental fluorosis index of the children in the town was 1.9, higher than that of the village of 1.8 (H=10.266, P < 0.01). The town had more children with fluoride tooth degree higher than Ⅱ [63.3%(57/90)]than the village did[48.3% (57/118), χ2=4.633, P < 0.05]. A 3-days diet records showed that children in the village ate more protein, calcium, vitamin C and so on but less dietary fiber, vitamin E, magnesium than those in the town did(all P < 0.01). Duplicate meals revealed that children in the town had more daily intake of magnesium, lithium, lead and less cadmium than those of the village did(P < 0.01 or < 0.05). Children in the village had higher intake of fluoride[(2.24±1.18)mg/d]than those of the town [(1.78±0.06)mg/d, t = 4.21, P < 0.01]. Conclusions Healthy diet can reduce the incidence of dental fluorosis or mitigate the degree of the impairment. This study can provide scientific basis for the future control and elimination of endemic fluorosis.

2005年北京12岁人群口腔健康行为调查

目的了解北京市12岁城乡学生口腔健康行为,为北京市口腔卫生保健工作提供信息支持。方法采用多阶段分层等容量随机抽样的方法,抽取北京市12岁城乡常住学生共396名,男女各半,按照《第三次全国口腔健康流行病学调查方案》设计的12岁学生问卷,对受检学生进行现场问卷调查,了解12岁学生饮食行为、口腔卫生行为、口腔卫生保健知识知晓情况及来源、对口腔卫生保健的态度、就医行为等。结果12岁学生的刷牙率为89％,每日刷牙两次者达到48％,同1995第二次流调相比提高10％,含氟牙膏使用率提高27％。90％左右的学生对口腔保健持积极态度,在“知识”,“信念”方面有很大提高,但“行为”与“知识”差距较大,1年内就医比例同1995年相比下降6％。结论北京市12岁学生口腔保健知识“知”、“信”比例较高,但“知”、“信”、“行”之间差距较大,农村表现更为突出。提示我们在今后的工作中要把工作重点放到激励学生做认知的一致。     

二种口香糖对牙面菌斑清除效果的观察

本文对１８一２４岁年龄青年共６０名，随机分为二组，用二种口香糖测定了各牙面菌斑清除效果。实验前，对全口６个指定牙进行了菌斑染色，测定面，近远中、颊舌面菌斑指数。用鼓漱方法作对照，观察各牙面菌斑的变化。实验后（咀嚼口香糖１０分钟）观察各牙面菌斑的变化。从三次记录各牙面菌斑指数，进行统计学分析。结是实验前和鼓漱后，菌斑指数有所下降，但阻嚼口香糖后各牙面菌斑指数明显下降。显著性试验，鼓漱后Ｐ＜０，０１，Ｐ＜０．０５，说明鼓漱对去除牙面软垢及粘附食物残渣有作用。实验后，显著性试验Ｐ＜０．０１各牙面菌斑指数下降值均有显著差异。结果表明，用口香糖清除牙面菌斑是有效的。二种口香糖同样有效。
