This study was undertaken to examine the prevalence of dental caries in Inuit (Eskimo) youth aged 5-22 years.
Both tooth-oriented indices and child-oriented caries patterns were recorded in a field study conducted in 1991 in Nain and Hopedale, Northern Labrador. Seventy-eight percent (N = 347) of all school-children in these two locations were examined by a single examiner.
Three percent of the population were caries free and 88 percent of those with caries experience had untreated dental decay. The mean combined dmft and DMFT per child for all ages was 6.85, while the mean combined dmfs and DMFS was 15.72. About 38 percent of subjects had pit and fissure caries; 2 percent had hypoplastic lesions; 4 percent had faciolingual caries; 31 percent had molar-approximal caries and 22 percent had faciolingual and molar-approximal caries, the most destructive caries pattern. About 68 percent of the 5-6-year-olds and 26 percent of the 15-22-year-olds experienced the most destructive pattern of decay in their primary and permanent dentitions, respectively.
Preventive measures should start well before the age of 5 years. Describing caries patterns according to the dentition type complemented the traditional indices.
本研究旨在调查5至22岁因纽特（爱斯基摩）青年的龋齿患病率。
在1991年于拉布拉多北部的奈恩和霍普代尔进行的一项实地研究中，记录了以牙齿为导向的指数和以儿童为导向的龋齿模式。这两个地点所有学童的78%（N = 347）由一名检查者进行了检查。
3%的人口无龋齿，有龋齿经历的人中88%有未经治疗的龋齿。所有年龄段儿童的平均dmft和DMFT总和为6.85，而平均dmfs和DMFS总和为15.72。约38%的受试者有窝沟龋；2%有发育不全病变；4%有颊舌面龋；31%有磨牙邻面龋，22%有颊舌面和磨牙邻面龋，这是最具破坏性的龋齿模式。在5至6岁儿童中，约68%在乳牙列中出现了最具破坏性的龋齿模式，在15至22岁青少年中，26%在恒牙列中出现了这种模式。
预防措施应在5岁之前就开始实施。根据牙列类型描述龋齿模式补充了传统指数。
