A partir dos resultados obtidos nesta pesquisa pode-se concluir que:
• O ensaio de abrasão por escovação promoveu a formação de valamento marginal em todas as resinas avaliadas, sendo que todas apresentaram um aumento no índice ao longo do tempo, porém sem diferenças estatisticamente significativas nos períodos correspondentes a 1 e 2 anos.
• As resinas 4Seasons e Tetric Ceram HB apresentaram aumento significativo do valamento marginal, quando comparadas com as resinas Filtek Supreme e Z350, após os períodos correspondentes a 4 e 6 anos, sem apresentar diferenças estatísticas entre si.
• A resina Filtek Supreme XT não apresentou aumento significativo do valamento marginal ao longo de todos os períodos avaliados sem apresentar diferenças estatísticas quando comparada com a Filtek Z350.
• A resina Filtek Z350 não apresentou aumento significativo do valamento marginal nos períodos correspondentes a 1, 2 e 4 anos. Entretanto, a média de valamento marginal após 6 anos diferiu estatisticamente das médias após os períodos correspondentes a 1 e 2 anos de escovação, sem apresentar diferença estatisticamente significante quando comparada com o período de 4 anos.
• Através da MEV, observou-se nas resinas 4Seasons e Tetric Ceram HB, nos períodos avaliados, imagens indicativas de deslocamento das partículas de carga, exposição e desgaste da matriz orgânica mais evidentes do que nas resinas Filtek Supreme e Filtek Z350.
