IgA antibodies to Streptococcus mutans in caries-resistant and -susceptible children.

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

Caries-free subjects or individuals with low caries susceptibility exhibited significantly higher (P less than 0.001) levels of naturally occurring salivary immunoglobulin A (IgA) and serum IgG, IgA, and IgM antibodies to a Streptococcus mutans ribosomal preparation than subjects with high caries susceptibility. Absorption of saliva and serum samples with S. mutans ribosomal preparations, but n...

Antibodies to indigenous and laboratory strains of Streptococcus mutans in saliva from children with dental caries and from caries-free children.

Whole, unstimulated saliva and dental plaque were collected from 63 children ages 6-13 years, 29 with dental caries and 34 without. If a child was infected with Streptococcus mutans, it was isolated from dental plaque and characterized. Saliva was tested for IgM, IgG, and IgA that would bind indigenous S. mutans, if present, and for antibodies that would bind 6 laboratory strains of S. mutans, ...

The Frequency of Streptococcus Mutans and Lactobacillus spp.in 3-5-year- old Children with and without Dental Caries

Abstract Background and Objective: The high occurrence of early childhood caries (ECC) is one of the most common problems in children dentistry. Streptococcus mutans and lactobacilli.spp are closely associated with the development of early childhood caries (ECC). Therefore, the aim of this study was to investigate the frequency of streptococcus mutans and lactobacilli.spp in 3-5 –year- old ch...

Effect of restorative treatment on mutans streptococci and IgA antibodies.

PURPOSE Streptococcus mutans has been implicated as the major causative agent of dental caries. Although restorative treatment for caries is thought to temporarily eliminate the carious challenge, there are few reports of alterations in salivary mutans streptococci (MS) numbers and no reports of changes in salivary IgA antibody to S. mutans following restorative treatment. METHODS This study ...
