RESUMO
La presente investigación evaluó, en un estudio in vitro, la eliminación química-mecánica de caries dentinaria, utilizando un producto experimental (2R2M1) a diferentes concentraciones. Para verificar el grado de remoción de dentina infectada de cada concentración se formaron 4 grupos, a cada grupo se asignaron 10 piezas molares permanentes con menos de 12 horas de haberse extraído. Las piezas se asignaron aleatoriamente a cada grupo, quedando de la siguiente manera: Grupo 1= 1%, Grupo 2= 2%, Grupo 3= 3% y Grupo 4= Remoción de dentina cariada con cucharilla (grupo control). Se aplicó el material por 2 minutos, se removió con cucharilla sin filo, de ser necesario se aplicaba una segunda y hasta una tercera vez. El grado de remoción se evaluó táctil y visualmente. Se utilizó el análisis de varianza (ANOVA) y el test de Tukey como pruebas estadísticas; se demostró diferencias significativas entre el grupo 2 y 3 con el grupo control, mostrando en ambos casos diferencias de medias arriba del 0.5. Con los resultados obtenidos se concluyó que el material experimental remueve dentina infectada y da mejores resultados que con la técnica convencional. Además el material experimental en concentraciones al 2% y 3% es más eficaz que al 1% y que el método tradicional de corte de dentina cariada con cucharilla.
The present investigation evaluated, in an in vitro study, the chemical-mechanical removal of dental caries, using an experimental product (2R2M1) at different concentrations. To verify the degree of removal of infected dentin from each concentration, 4 groups were formed, each group was assigned 10 permanent molar pieces less than 12 hours after being extracted. The pieces were randomly assigned to each group, remaining as follows: Group 1 = 1%, Group 2 = 2%, Group 3 = 3% and Group 4 = Removal of carious dentin with a spoon (control group). The material was applied for 2 minutes, it was stirred with a dull spoon, if necessary a second and even a third time was applied. The degree of removal was evaluated tactilely and visually. Analysis of variance (ANOVA) and Tukey's test were used as statistical tests; Significant differences were demonstrated between groups 2 and 3 with the control group, showing mean differences above 0.5 in both cases. With the results obtained, it was concluded that the experimental material removes infected dentin and gives better results than with the conventional technique. In addition, the experimental material in concentrations of 2% and 3% is more effective than 1% and than the traditional method of cutting carious dentin with a spoon.
