title: [A comparative study of the bacterial dental plaque formation on fixed dentures with different surface characteristics].
abstract: The accumulation of dental plaque on fixed prostheses made of various biomaterials is influenced by the roughness of the surface. For the investigation of this aspects it was necessary of a method rapid, facile and cheaper in comparison with bacterial culturing and identification which is laborious and expansive. In this study we followed the accumulation of dental plaque on biomaterials like chrome-cobalt and gaudent polished and unpolished, at different periods of time (3 and 14 days). We observed that after 3 days the aspect is predominant coccoid and after 14 days is predominant bacillary. On unpolished crowns the width of dental plaque is greater and on gaudent crowns the plaque is structural organised around of filamentous organisms.
