Tamanho de amostra e estimativa de custo em levantamento epidemiológico de cárie dentária

Abstract: O objetivo do presente estudo foi analisar como a prevalência e a distribuição da cárie dentária influenciam o tamanho da amostra em levantamentos epidemiológicos, e os custos para sua realização. Foram utilizados dados de levantamentos realizados em escolares de 12 anos em Bauru nos anos de 1976, 1984, 1990, 1994 e 2001, e em Piracicaba nos anos de 2001 e 2005. Os tamanhos amostrais foram dimensionados considerando-se a média e o desvio padrão obtidos, fixando-se erro amostral em 1%, 2%, 5% e 10%. Os custos f… Show more

“…In some countries with huge populations (as in Brazil), performing epidemiological population-based studies is usually very expensive and requires a great amount of both human and technological resources. In addition, clinical examinations are needed in some studies, increasing the resources needed and hence making them unfeasible 2 , 3 . The self-perception of health associated with treatment needs, as well as the degree of satisfaction with health status, have been used more frequently in health surveys.…”

“…However, numerous works using this index have been identified, almost all using the "full mouth" method in order to obtain prevalence data and manifestation of dental caries in various countries, populations, age groups and study approaches, confirming the wide use of this index [4,[18][19][20][21].…”

“…From the epidemiological point of view, the reduced prevalence of dental caries, a trend that can be seen in Brazil and several countries, determines the need to increase the sample size of individuals to be examined [4] to obtain a representative probability sample. This represents an increase in costs of epidemiological surveys in oral health.…”
