The aim of this study was to determine the effect of oral environment stabilization (OES) on the counting of Streptococcus mutans in high-caries-risk pregnant women participants of a prevention program in a public teaching institution. The sample was composed of 30 pregnant women aged 18 to 43 years, who looked for treatment at the Preventive Dentistry Clinic of the Araraquara Dental School, UNESP. Saliva samples were collected before and after the OES procedures and were forwarded to the pathology for observation and quantification of S. mutans CFU. There was a decrease in the number of S. mutans CFU, which was significantly different (p<0.0001) between samples. Considering the age group, 70.0% were between 18 to 30 years old and 30.0% belonged to the 31-43-year-old age group. Data related to the pregnancy period showed that 73.4% were in the second trimester, 13.3% in the first and 13.3% in third trimester. OES showed to be an effective clinical procedure in diminishing the number of S. mutans CFU in the saliva of high-caries-risk pregnant women. This management is simple and effective, corresponding to the basic treatment needs of pregnant women that search dental care in this public service.
