Resumo
The current discussion about the importance of intracanal dressings and the effect of vehicles on calcium
hydroxide pastes is justified by controversy concerning the achievement of complete disinfection after
preparation of infected root canals and the real antimicrobial effect of these vehicles. The aim of this study is
to investigate the role of vehicles in the antimicrobial effect of calcium hydroxide pastes. Well-conducted
research about the characteristics of calcium hydroxide, such as antimicrobial potential, physico-chemical
aspects and histocompatibility, gives credibility to the choice of this medication in several clinical situations.
Different vehicles have been added to calcium hydroxide in an attempt to enhance its properties. Scientific
reasoning indicates the use of hydrosoluble vehicles (distilled water, saline) associated with calcium
hydroxide because of their chemical characteristics of dissociation, diffusibility and filling capability which
are decisive for the biological behavior, i.e., antimicrobial qualities and induction of tissue repair.
