Análisis de la variación de los niveles de S. mutans en saliva de pacientes libres de caries: comparando la acción de la clorhexidina en barniz y colutorios / Salival analysis on mutans streptococci levels in free caries patients: comparison of chlorhexidine varnish and chlorhexidine gluconato mouthrinses

RESUMEN

This study evaluated the reduction on Mutans Streptococci levels in free caries patients with the use of 10 por ciento chlorhexidine varnish, and chlorhexidine mouthrinses in two different concentrations 0.1 percent and 0.12 percent. After finished the restoratives treatment 48 patients caries free were divided in four groups of 12 patients each one. Group A treatted with 10 percent CHX varnish in one time; Group B mouth rinse with CHX, 12 percent twice a day for 20 days; Group C mouth rinse with CHX 0,1 percent twice a day during 20 days; and group D as control. Group A show the better reduction of s. mutans in saliva by Cariscreen method. The period of the study was two month
