A large study of the dental health of children in the Canadian province of Alberta was undertaken in 1985. A ten per cent sample of 13-year old children (3117) was selected. This study reports on the gingival status of the children using the community periodontal index of treatment needs (CPITN). The findings show that the children have few periodontal problems and that the main treatment needs are oral prophylaxis and improvement in personal oral hygiene. The World Health Organisation guideline for the year 2000 in respect of the long-term goals for periodontal health is met in this Canadian population.
1985年，加拿大艾伯塔省针对儿童牙齿健康开展了一项大型研究。选取了13岁儿童的10%作为样本（共3117名）。本研究采用社区牙周治疗需要指数（CPITN）报告了这些儿童的牙龈状况。研究结果表明，这些儿童几乎没有牙周问题，主要的治疗需求是口腔预防和个人口腔卫生的改善。加拿大的这一人群达到了世界卫生组织2000年关于牙周健康长期目标的指导标准。
