To determine the prevalence and severity of dental caries among school children of St. Vincent and The Grenadines. Also, to establish baseline data on dental caries and determine the extent to which the present oral health care system is meeting dental needs.
National cross-sectional survey utilising the World Health Organization's pathfinder methods. Dental examinations were conducted from October to November 1991 by three trained examiners.
A total of 1648 students, 21% of school children in St. Vincent and The Grenadines, were sampled through multistage systematic sampling.
Dental caries was diagnosed clinically according to the World Health Organization's diagnostic criteria.
Caries prevalence in the permanent dentition was 69.4%, ranging from 68 to 73% according to gender and geographic location. In the primary dentition caries prevalence was 76.6%. Mean DMFT for the survey population was 2.69, dmft was 3.25, while the DMFT scores for gender and location types varied from 2.39 to 3.25. DMFT at 12 years was 3.25. No difference in caries prevalence was observed between gender in the permanent dentition but prevalence was significantly different in the primary dentition being higher among boys. Prevalence was significantly higher in the urban population relative to the rural population. The decayed component constituted 92% of DMFT and 91% of dmft.
Moderate caries severity and high levels of untreated decay were found in both primary and permanent teeth. The results emphasise the need for continuous surveillance and for appropriate intervention and prevention programmes.
确定圣文森特和格林纳丁斯学龄儿童龋齿的患病率和严重程度。此外，建立龋齿的基线数据，并确定当前口腔保健系统满足口腔需求的程度。
采用世界卫生组织的探索性方法进行全国横断面调查。1991年10月至11月，由三名经过培训的检查人员进行牙科检查。
通过多阶段系统抽样，共抽取了1648名学生，占圣文森特和格林纳丁斯学龄儿童的21%。
根据世界卫生组织的诊断标准临床诊断龋齿。
恒牙列龋齿患病率为69.4%，根据性别和地理位置在68%至73%之间。乳牙列龋齿患病率为76.6%。调查人群的平均恒牙龋失补指数（DMFT）为2.69，乳牙龋失补指数（dmft）为3.25，而不同性别和地区类型的DMFT得分在2.39至3.25之间。12岁儿童的DMFT为3.25。恒牙列中不同性别间龋齿患病率无差异，但乳牙列中男孩的患病率显著高于女孩，且城市人口的患病率显著高于农村人口。龋损部分占DMFT的92%，占dmft的91%。
乳牙和恒牙均存在中度龋齿严重程度和高水平的未治疗龋损。结果强调了持续监测以及开展适当干预和预防项目的必要性。
