Streptococcus Mutans Reduction Early Mother-infant Transmission
27 april 2021 uppdaterad av: Marine Ortiz Magdaleno, Biochemical and Microbiology Laboratory, Faculty of Dentistry, Autonomous University of San Luis Pot
Enhancing Effect of the Application of 1% Chlorhexidine Varnish With Silane Fluoride and Oral Health Promotion on the Streptococcus Mutans Counts Reduction in Pregnant Women and on Early Mother-infant Transmission
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.

Detaljerad beskrivning
The aim of this study was to evaluate the enhancing effect of 1% chlorhexidine varnish together with silane fluoride re-mineralizing varnish and oral health promotion strategy on the reduction of S. mutans counts in saliva of pregnant women and the early mother-infant transmission until the first six months of age of the newborn.
Methods: An open, random clinical trial of parallel groups was performed.
56 pregnant women free of caries were studied prospectively and longitudinally since the third trimester of gestation until 6 months after giving birth, the newborns were also assessed until reaching 6 months of age.
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.
Identification of S. mutans was performed through PCR.
The DNA of the isolates identified molecularly as S. mutans was used for a second PCR reaction using the arbitrary primer OPA-O2 to determine the homology among the samples of isolated bacteria from the mother-child pair.

Experimentell: Pregnant women to whom applied silane fluoride
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.

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

Caries prevalence assessment in pregnant womens
Tidsram: Basal measurement, at the beginning of the third trimester of gestation.
|
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.
