The SBBrasil 2010 Project (SBB10) was designed as a nationwide oral health epidemiological survey within a health surveillance strategy. This article discusses methodological aspects of the SBB10 Project that can potentially help expand and develop knowledge in the health field. This was a nationwide survey with stratified multi-stage cluster sampling. The sample domains were 27 State capitals and 150 rural municipalities (counties) from the country's five major geographic regions. The sampling units were census tracts and households for the State capitals and municipalities, census tracts, and households for the rural areas. Thirty census tracts were selected in the State capitals and 30 municipalities in the countryside. The precision considered the demographic domains grouped by density of the overall population and the internal variability of oral health indices. The study evaluated dental caries, periodontal disease, malocclusion, fluorosis, tooth loss, and dental trauma in five age groups (5, 12, 15-19, 35-44, and 65-74 years).
