ABSTRACTThe oral health level and the role of Streptococcus mutans and dental plaque accumulation in the development of dental caries are important factors for the analysis and determination of importance as a risk factors, it have been demonstrated in preschool and scholars children, deficient hygiene practices, and for these reasons is important to use microbiological procedures in order to evaluate quantitative and qualitative the dental plaque conditions. The aim of this work is to determine the prevalence of dental caries in a group of school children from 10-13 years old from the urban area in Zacatecas city and determinate the presence of S. mutans in saliva in order to establish a relation between DMFT and the amount of S. mutans. It was determined the DMFT and the SOHI as well as the ufcs/mL of S. mutans in 150 children of both sex in a school of urban area in Zacatecas city, we found a 56% prevalence of dental caries and a correspondence between the S. mutans levels and the DMFT index; for this reason is important to control the amount of S. mutans in dental plaque.
