NCT04868513

Brief Summary

Evidence exists on the vertical transmission of Streptococcus mutans from the mother to her children. This transmission can be prevented by maintaining maternal oral health during pregnancy.

Outcome Measures

Primary Outcomes (8)

  • Caries prevalence assessment in pregnant womens

    For this purpose, the Decayed, Missing, and Filled Teeth Index was used to measure the prevalence of caries. This index is based on in-field clinical examination of individuals by using a probe, mirror and cotton rolls, and simply counts the number of decayed, missing (due to caries only) and restored teeth the number of participants with prevalence of caries will be reported.

    Basal measurement, at the beginning of the third trimester of gestation.

  • Streptococcus mutans levels identified in pregnant womens

    In this measurement was identified the S. mutans counts in the saliva of pregnant women after the applications of 1% chlorhexidine varnish together with the application of silane fluoride re-mineralizing varnish or only with the application of silane fluoride, was reported the distribution of cariogenic Streptococcus levels in mothers.

    In this measurement was identify the S. mutans counts in the saliva of pregnant women after the applications of 1% chlorhexidine varnish together with the application of silane fluoride re-mineralizing varnish or only with the application of silane fluoride. Will be reported the distribution of cariogenic Streptococcus levels in mothers.

    Six months after the birth of the child

  • Genotypes of the isolates of S. mutans in pregnant womens.

    The genotypes describes an organism's complete set of genes, in this study, was determined the homology among the samples of isolated bacteria from the mother-child pair. The molecular PCR test was implemented for the identification. Will be reported the % of S. mutans genotypes isolated from the mothers of both groups to the strains isolated from the newborns.

    Three months after the birth of the child.

  • Streptococcus mutans levels identified in childrens

    In this measurement was identified the S. mutans counts in the saliva of the children. Will be reported the distribution of cariogenic Streptococcus levels in the children.

Study Arms (4)

Pregnant women to whom applied silane fluoride

EXPERIMENTAL

We applied 0.1% silane fluoride (Fluor Protector, Ivoclar Vivadent AG™) as varnish in all teeth on all faces as a promotion strategy on the reduction of S. mutans.

Drug: Pregnant women to whom applied silane fluoride

Pregnant women to whom applied silane fluoride + 1% chlorhexidine

EXPERIMENTAL

We applied 0.1% silane fluoride (Fluor Protector, Ivoclar Vivadent AG™) and 1% chlorhexidine (Cervitec, Ivoclar Vivadent AG™), both applied as varnish, with a 1 min interval between applications, in all teeth on all faces, using the standardized technique indicated by the manufacturer as a promotion strategy on the reduction of S. mutans.

Drug: Pregnant women to whom applied silane fluoride + 1% chlorhexidine

Children of the pregnant women to whom it was applied silane fluoride

NO INTERVENTION

The children not given any intervention, they were only subjected to a microbiological and clinical examination.

Masking Details
Two groups were formed assigning 28 women to each intervention group. G-I received 0.1% silane fluoride applied as varnish in each visit. G-II women's teeth were coated with 0.1% silane fluoride and 1% chlorhexidine. For the primary culture, CRT Bacteria® system (Ivoclar-Vivadent™) was used for the growth and identification of cariogenic Streptococci.
