The plaque-control potential of commercially available amylase, lipase and protease was evaluated by observing their effects on coaggregation and on bacterial viability within various plaque microcosms. A quantitative coaggregation assay indicated that protease significantly inhibited the extent of coaggregation of Actinomyces naeslundii and Streptococcus(More)
OBJECTIVE Despite the targeted and incidental exposure of the oral cavity to probiotic bacteria, relatively little information is available concerning their bacteriological effects or ecological fate in this environment. We have investigated the effects of an oral probiotic bacterium, Lactobacillus reuteri on salivary biofilm microcosms. DESIGN Nascent in(More)
Salivary host-defence peptides include defensins, histatins and cathelicidin. We have investigated the effects of these peptides on the microbial composition of dental plaques. Salivary consortia, established within hydroxyapatite disc models, were exposed during development to physiological levels of human neutrophil proteins (HNP) 1 and 2; human β(More)
The effect of humoral immunity on the composition of the oral microbiota is less intensively investigated than hygiene and diet, in part due to a lack of simple and robust systems for investigating interactions between salivary immunoglobulins and oral bacteria. Here we report the application of an ex situ method to investigate the specificity of salivary(More)
