Objetivo
Evaluar in vitro el efecto del gluconato de clorhexidina al 0.12% en diferentes tiempos de exposición (8, 16, 24, 32, 40 y 48 horas) en la inhibición de la adherencia del Streptococcus mutans en el metil-metacrilato autopolimerizable.
Material y métodos
Estudio de tipo experimental, por grupos de comparación. Se utilizaron 120 muestras de metil-metacrilato autopolimerizable divididas en seis grupos (subgrupo experimental y subgrupo control).
Resultados
No se encontraron diferencias en las medias de los primeros cuatro grupos en sus dos modalidades (p > 0.05). En los grupos restantes existieron diferencias significativas entre el subgrupo control y el subgrupo experimental (p < 0.001).
Conclusiones
Los resultados demuestran que la adherencia de Streptococcus mutans en el metil-metacrilato autopolimerizable in vitro se inhibe después de varias aplicaciones de gluconato de clorhexidina al 0.12%.
Palabras clave: Gluconato de clorhexidina; Streptococcus mutans; metil-metacrilato autopolimerizable; restauración provisional
Objective
The purpose of the present study was to evaluate in vitro the effect of Chlorhexidine gluconate at 0.12% in the adherence inhibition of Streptococcus mutans with provisional restorative at different exposure times (8, 16, 24, 32, 40, 48 hours).
Material and methods
The study was of experimental type, for comparison groups. Total of 120 samples of Autopolymerizing PMMA divided in six groups were used (experimental and control groups).
Results
No significant differences were found in medias of the first four groups (p > 0.05). The others showed significant difference between the experimental and control subgroups.
Conclusion
The results demonstrated that the adherence of Streptococcus mutans to Autopolymerizing PMMA in vitro is inhibited after several applications of Chlorhexidine gluconate at 0.12%.
Key words: Chlorhexidine gluconate; Streptococcus mutans; autopolymerizing PMMA; provisional restorative
