Abstract: | The aim of this study was to investigate in vitro the antimicrobial activity of calcium hydroxide in combination with several vehicles against some microorganisms commonly isolated from root canals. Antimicrobial activity was determined by the agar diffusion method. Stainless-steel cylinders were placed on each inoculated agar medium. The test medicaments and their controls were placed inside the cylinders. The zones of growth inhibition were measured and recorded after incubation for each plate and the results were analyzed statistically (ANOVA). The in vitro antimicrobial effects of the medications were ranked from strongest to weakest as follows: Ca(OH)2 + CMCP + glycerine, Ca(OH)2 + CMCP, Ca(OH)2 + glycerine, Ca(OH)2 + anesthetic, Ca(OH)2 + saline, Ca(OH)2 + H2O, Ca(OH)2 + polyethyleneglycol. The pastes with oily vehicles showed significantly larger mean zones of inhibition compared to those with aqueous or viscous vehicles. It was concluded that diffusion and antimicrobial activity of calcium hydroxide were affected by the type of vehicle used.

metadata.dc.description.abstractalternative: | O objetivo deste trabalho foi investigar in vitro a atividade antimicrobiana do hidróxido de cálcio em combinação com vários veículos contra alguns microrganismos mais frequentemente isolados dos canais radiculares. A atividade antimicrobiana foi determinada pelo método de difusão no ágar. Cilindros de aço inoxidável foram colocados sobre as placas de agar já inoculadas, dentro dos quais os medicamentos testados e seus controles foram introduzidos. As zonas de inibição do crescimento microbiano foram medidas e anotadas após o período de incubação de cada placa e os resultados foram analisados estatisticamente. A atividade antimicrobiana in vitro dos medicamentos testados, em ordem decrescente, foi: Ca(OH)2 + PMCF + glicerina, Ca(OH)2 + PMCF, Ca(OH)2 + glicerina, Ca(OH)2 + anestésico, Ca(OH)2 + salina, Ca(OH)2 + H2O, Ca(OH)2 + polietilenoglicol. Pastas com veículos oleosos produziram as maiores zonas de inibição, quando comparadas com as com veículos aquosos ou oleosos. Concluimos que a habilidade de difusão e a atividade antimicrobiana do hidróxido de cálcio estão relacionadas com os tipos de veículos utilizados |
