BACKGROUND This study aims to investigate bacterial adhesion on different titanium and ceramic implant surfaces, to correlate these findings with surface roughness and surface hydrophobicity, and to define the predominant factor for bacterial adhesion for each material. METHODS Zirconia and titanium specimens with different surface textures and wettability (5.0 mm in diameter, 1.0 mm in heigh...

UNLABELLED Although saliva is widely recognized as a primary source of carbon and nitrogen for growth of the dental plaque biofilm community, little is known about how different oral bacteria utilize specific salivary components. To address this question, 32 strains representing 16 genera commonly isolated from early plaque biofilms were compared for growth over two transfers in stimulated (by ...

An antibacterial substance from Streptococcus sanguinis (S. sanguinis) is known to have an inhibitory effect on putative periodontal pathogens, but its inhibitory effect on pathogens of oral candidiasis is unknown. In this study, intracellular and exocrine proteins were extracted from S. sanguinis. The antagonistic effect of the protein extracts on Prevotella intermedia (P. intermedia) and Porp...

Biofilms are aggregates of bacterial cells attached to a surface. Oral biofilms (" plague ") are major contributors to tooth decay (dental caries) and are a potential conduit for infection and disease. These biofilms have been shown to be resistant to removal by traditional oral hygiene practices. Novel prophylactic and in situ treatment methods are therefore needed to address this problem. Whi...

The purpose of this study was to determine the occurrence and nature of immunoglobulin A1 (IgA1) protease activity in members of the genus Gemella and related taxa. Among a total of 22 Gemella strains belonging to the four species Gemella haemolysans, Gemella morbillorum, Gemella sanguinis, and Gemella bergeriae and four reference strains of the species Helcococcus kunzii, Facklamia hominis, an...
