Dental caries is a chronic infectious disease that needs at least four components to develop. As a susceptible host, a pathogenic microbiota, a high-sucrose diet and time. This work assess the relationships between Streptococcus mutans and dental plaque; Streptococcus mutans and IgA antibodies in children with and without caries experience. In order to achieve this goal we have used Mitis Salivarius bacitracin agar (DIFCO) to determine the colony forming units (CFU/mL), the simplified oral hygiene index (SOHI) for measuring bacterial plaque and ELISA for antibody detection. The results obtained have not shown any correlations between colony forming units of S. mutans and IgA antibodies. A significant correlation was found between bacterial plaque index and specific IgA in children with carious lesions.
