Resumo
Foram testados, em sessenta e quatro pré-molares humanos recém-irrompidos, quatro procedimentos de limpeza de fóssulas e fissuras, realizados antes do condicionamento ácido e da aplicação de dois selantes, um fotopolimerizável e outro de polimerização quimicamente ativada. Após essas operações, os dentes foram desgastados até a obtenção de secções para estudo ao microscópio, em que se verificou que ambos os selantes se comportaram de maneira similar, nas regiões média e inferior, porém o selante de polimerização química apresentou projeções mais extensas. Quanto aos métodos de limpeza testados, a profilaxia mostrou-se mais eficiente apenas nas regiões média e inferior; na região superior, nenhuma diferença foi observada em função do método de limpeza das fissuras .

Abstract
Sixty-four newly erupted human bicuspid were used in this in vitro study. Four different pit and fissure cleaning procedures were accomplished before acid conditioning followed by the application of photo cured or chemical cured sealants. Ground sections were analysed underpolarized light. Results indicated that both sealants showed similar behaviour at the middle and lower portions of pits and fissures; the chemical cured sealant showed longer tags. Among the different cleaning procedures prophylaxis was the method of choice.
