The purpose of this study was to assess the dental health of Navajo preschool children, a population about whom little dental information is published.
Caries data were collected and analyzed for 2,003 Navajo children aged 3-5 years in the Head Start program, and for a convenience sample of 115 children younger than three years old from the Women, Infants and Children (WIC) program.
Each age group had an extremely high mean dmfs; however, as much as 70 percent of this index comprised treated surfaces. Maxillary anterior caries was observed in the WIC children under two years of age and posterior proximal caries was observed as early as two years of age. The prevalence of maxillary anterior caries reached a maximum of 68 percent in the three-year-old Head Start children, and may be associated with the high level of posterior caries in this population.
Most children in this population may be considered at risk for developing caries. This Navajo preschool population has perhaps the earliest caries onset, among the highest caries prevalence, and among the highest level of treatment of any reported population.
本研究旨在评估纳瓦霍族学龄前儿童的口腔健康状况，该人群鲜有口腔方面的公开信息。
收集并分析了参与“领先开端计划”的2003名3至5岁纳瓦霍族儿童的龋齿数据，以及来自妇女、婴儿和儿童（WIC）计划的115名3岁以下儿童的便利样本数据。
每个年龄组的平均dmfs都极高；然而，该指数中多达70%为已治疗的牙面。在WIC计划中，两岁以下儿童出现上颌前牙龋齿，而后牙邻面龋齿最早在两岁时出现。在参与“领先开端计划”的三岁儿童中，上颌前牙龋齿患病率最高达到68%，这可能与该人群中后牙龋齿的高发有关。
该人群中的大多数儿童可能被视为有患龋齿的风险。这个纳瓦霍族学龄前人群的龋齿发病时间可能最早，龋齿患病率最高，且在所有已报道人群中治疗水平也最高。
