Examine the association between marginalization and fluorosis with caries experience in Mexican rural children aged 8-12, in Oaxaca, Mexico.
Cross-sectional study of 283 rural schoolchildren selected from two locations with high and medium levels of marginalization where the water fluoride concentration ranged from 2.0 to 2.5 ppm/F. Caries was evaluated using the DMFT index and dental fluorosis with the Thylstrup-Fejerskov Index (TFI). Socioeconomic data were collected from participants' parents, with data on the children's characteristics collected from them via a questionnaire.
The prevalence of caries was 72.4% (DMFT ≥1) in the permanent dentition. The prevalence of fluorosis was 98.0% (TFI ≥4=71.4%). 54.8% of the children brushed their teeth two or more times daily. In logistic regression children living in high levels of marginalization were more likely to present caries (OR=2.11, 95% CI 1.13 - 3.93) than children living in medium levels. Children with severe fluorosis (TFI ≥4) (OR=1.93, 95% CI 1.06 - 3.53) were more likely have caries than those with TFI ⟨3.
Rural children with a high level of marginalization and fluorosis (TFI ≥4) were more likely to present caries. Poor oral hygiene and low dental service levels were found in both marginalized areas. Populations with medium/high marginalization are more susceptible to caries.
研究墨西哥瓦哈卡州8至12岁农村儿童中，边缘化和氟中毒与龋齿经历之间的关联。
对283名农村学童进行横断面研究，这些学童选自两个边缘化程度高和中等的地区，当地水氟浓度在2.0至2.5 ppm/F之间。使用DMFT指数评估龋齿情况，用蒂尔斯楚普-费耶斯科夫指数（TFI）评估氟斑牙情况。从参与者的父母那里收集社会经济数据，并通过问卷从他们那里收集有关儿童特征的数据。
恒牙列中龋齿患病率为72.4%（DMFT≥1）。氟斑牙患病率为98.0%（TFI≥4 = 71.4%）。54.8%的儿童每天刷牙两次或更多次。在逻辑回归分析中，生活在高度边缘化地区的儿童比生活在中度边缘化地区的儿童患龋齿的可能性更高（OR = 2.11，95% CI 1.13 - 3.93）。患有重度氟斑牙（TFI≥4）的儿童（OR = 1.93，95% CI 1.06 - 3.53）比TFI＜3的儿童患龋齿的可能性更高。
高度边缘化和氟斑牙（TFI≥4）的农村儿童患龋齿的可能性更高。在两个边缘化地区均发现口腔卫生差和牙科服务水平低的情况。中度/高度边缘化人群更容易患龋齿。
