A study was undertaken to estimate dental caries prevalence and treatment need among racial/ethnic minority schoolchildren in the Bronx. Oral examinations were conducted on 148 second graders, 193 fourth graders and 299 sixth graders in three different schools. A single examiner trained to use the DMFS index according to National Institute of Dental and Craniofacial Research (NIDCR) diagnostic criteria and procedures examined all the children between November 1999 and July 2000. The study revealed that 39% of the children exhibited dental caries experience in their permanent dentition (mean DMFS = 1.45), treatment need (D/DMFS = 28%); 26.4% of children in their primary dentition (mean dfs = 1.01) and treatment need (d/dfs = 18%). Hispanic children (mean DMFS = 1.71) had higher dental caries experience compared to African-Americans (mean DMFS = 1.14). This was found to be statistically significant (p = 0.004). Treatment need in Hispanics was (30%, 17%) and in African-Americans (30%, 18%) in permanent and primary dentition respectively. Treatment need was highest among sixth grade African-Americans in their permanent dentition and in second grade Hispanics in the primary dentition. The study showed a difference in dental caries prevalence, but the treatment need percentages did not differ between Hispanics and African-Americans in both dentition.
一项研究旨在估计布朗克斯区少数族裔学童的龋齿患病率和治疗需求。对三所不同学校的148名二年级学生、193名四年级学生和299名六年级学生进行了口腔检查。在1999年11月至2000年7月期间，由一名经过培训、按照美国国立牙科和颅面研究所（NIDCR）诊断标准及程序使用DMFS指数的检查者对所有儿童进行了检查。研究显示，39%的儿童恒牙列有龋齿经历（平均DMFS = 1.45），需要治疗（D/DMFS = 28%）；26.4%的儿童乳牙列有龋齿经历（平均dfs = 1.01），需要治疗（d/dfs = 18%）。与非裔美国人（平均DMFS = 1.14）相比，西班牙裔儿童（平均DMFS = 1.71）有更高的龋齿经历。这在统计学上具有显著性（p = 0.004）。西班牙裔儿童恒牙列和乳牙列的治疗需求分别为（30%，17%）和非裔美国人（30%，18%）。恒牙列中六年级非裔美国儿童和乳牙列中二年级西班牙裔儿童的治疗需求最高。该研究显示了龋齿患病率的差异，但西班牙裔和非裔美国人在两个牙列中的治疗需求百分比没有差异。
