The study is a cross-sectional survey on the situation of dental caries in the population living in the Red river delta and in the Mekong river delta. The result of the study indicated that: 1. In both areas, the percentage of primary dentition is very high. The percentage of caries in the permanent dentition and DMFT index increases a cross the age groups in both areas. In the Mekong river delta, the situation of caries in children is more serious. 2. The percentage of adults who had dental caries is very high in both areas and the DMFT index in Mekong river delta is higher. 3. Almost all children 6-14 years old who had dental caries are untreated in both areas. In other groups, the percentage of filling teeth is higher but it is still in very low level and also lower than 8% for all age groups
