Ação do Profident sobre os tecidos gengivais. 2. Efeitos da ação do jato de bicarbonato de sódio sobre os tecidos gengivais, sob variação do ângulo de incidência. Análise histológica.

Abstract

The effect of sodium bicarbonate jet (Profident System) on the gingival tissue was tested with comparison of application from 2 different angles: the angulation recommended by the manufacturer and ponted to the occlusal surface. The results showed a definite influence of the angulation on tissue trauma, with lesser degrees of injury when the modified angulation was applied.
