To assess the prevalence, extent, and risk indicators of tooth loss in a representative young urban population from south Brazil.
A representative sample was drawn using a multi-stage probability cluster sampling strategy, and consisted of 612 subjects 14-29 years of age in the metropolitan area of Porto Alegre, Brazil. A clinical examination was carried out by 4 calibrated examiners in a mobile examination center.
The prevalence of tooth loss was 44.8%, 26%, and 60%, and the mean tooth loss was 1.4, 0.6, and 2.4 teeth in the age groups 14-29, 14-19 and 25-29 years, respectively. First molars were the most frequently missing teeth, and the mandibular incisors and canines were the least missing teeth. Tooth loss increased sharply with age, and was similar in males and females. Having > or =4 missing teeth was significantly associated with low socioeconomic status and heavy smoking, and was significantly more likely in persons who had > or =2 teeth with caries/fillings and/or > or =5 mm attachment loss.
Tooth loss is a dental health concern in this young Brazilian population. Community-based oral diseases prevention programs targeting groups having these risk factors should be implemented to reduce tooth loss.
评估巴西南部一个具有代表性的年轻城市人口的牙齿缺失患病率、程度及风险指标。
采用多阶段概率整群抽样策略抽取一个具有代表性的样本，该样本由巴西阿雷格里港大都市区612名14 - 29岁的受试者组成。由4名经过校准的检查人员在一个流动检查中心进行临床检查。
在14 - 29岁、14 - 19岁和25 - 29岁年龄组中，牙齿缺失患病率分别为44.8%、26%和60%，平均缺牙数分别为1.4颗、0.6颗和2.4颗。第一磨牙是最常缺失的牙齿，下颌切牙和尖牙是最少缺失的牙齿。牙齿缺失随年龄急剧增加，且在男性和女性中相似。有≥4颗牙齿缺失与社会经济地位低和大量吸烟显著相关，并且在有≥2颗龋齿/补牙和/或≥5毫米附着丧失的人群中显著更常见。
在这个年轻的巴西人群中，牙齿缺失是一个口腔健康问题。应实施针对具有这些风险因素群体的社区口腔疾病预防项目，以减少牙齿缺失。
