Salivary immunoglobulin A and serum antibodies to Streptococcus mutans ribosomal preparations in dental caries-free and caries-susceptible human subjects.

The Comparison of Proteins Elaborated by Streptococcus mutans Strains Isolated from Caries Free and Susceptible Subjects

Amount and avidity of salivary and serum antibodies against Streptococcus mutans in two groups of human subjects with different dental caries susceptibility.

Immunoglobulin A (IgA) and IgG antibodies against Streptococcus mutans K1R and 10449 were measured in serum and in stimulated whole saliva from two groups of naval recruits, representing high or low caries susceptibility. The antibody assays were performed by using the enzyme-linked immunosorbent assay, and the results were expressed by a method able to estimate the amount of high-avidity and t...

Effects of Short-term Consumption of Probiotic Yogurt on Streptococcus Mutans and lactobacilli Levels in 18-30 Years Old Students with Initial Stages of Dental Caries in Ahvaz City

Background and Objectives: Dental caries, caused by oral microbial flora, is considered as one of the most common infectious diseases in human. The aim of this study was to determine the effect of short-term consumption of probiotic yogurt containing bifidobacterium lactis on salivary streptococcus mutans and lactobacilli in students with initial stages of dental caries. Materials and Methods:...

Antigenic characterization of fimbria preparations from Streptococcus mutans isolates from caries-free and caries-susceptible subjects.

The adhesion of pathogenic bacteria to the host surface is an essential step in the development of numerous infections, including dental caries. Attachment of Streptococcus mutans, the main etiological agent of human dental caries, to the tooth surface may be mediated by glucan synthesized by glucosyltransferase (GTF) and by cell surface proteins, such as P1, which bind to salivary receptors. F...

Differential reactivity of salivary igA and igG against streptococcus mutans proteins in humans with different caries experience.

Dental caries is an infectious disease which still constitutes a public health concern. It begins at an early age and is caused mainly Streptococcus mutans (S. mutans). The aim of this study was to characterize the salivary humor immune response to S. mutans proteins in patients with caries, with history of caries and without caries, in order to determine which S. mutans proteins participate in...
