Abstract
El presente estudio de tipo experimental, tuvo como objetivo comparar el efecto erosivo in
vitro de las bebidas carbonatadas sobre dos resinas compuestas y un ionómero de vidrio.
La población de estudio estuvo conformada por treinta bloques de 10 mm de diámetro por
4mm de altura de cada uno de los materiales de restauración estética en estudio,
distribuidos en diez unidades para cada uno de los tres grupos, “control” y grupos de
estudio. Los dos grupos experimentales fueron sometidos a la acción de las bebidas
carbonatadas por 15 minutos durante 14 días a temperatura ambiente, después del cual se
midió la microdureza mediante el sistema VICKERS, al igual que el grupo control.
Los resultados obtenidos muestran que existe diferencia estadística altamente significativa
entre las variaciones de la microdureza de los 3 materiales de restauración estética, en
donde se observó que la resina hibrida presentó mayor disminución de la microdureza,
seguida por el ionómero de vidrio y finalmente la resina bulk fill luego de ser expuestas a
ambas bebidas carbonatadas.
Se concluye que ambas bebidas carbonatadas tienen un efecto erosivo importante, sin
embargo, no existe diferencia estadística del efecto erosivo entre la coca cola y la inka
cola sobre los 3 materiales de restauración estética.
The present experimental study aimed to compare the in vitro erosive effect of carbonated drinks on two composite resins and a glass ionomer. The study population consisted of thirty blocks of 10 mm in diameter by 4 mm in height of each of the aesthetic restoration materials under study, distributed in ten units for each of the three groups, "control" and study groups. The two experimental groups were subjected to the action of carbonated beverages for 15 minutes during 14 days at room temperature, after which the microhardness was measured using the VICKERS system, as was the control group. The results obtained show that there is a highly significant statistical difference between the variations of the microhardness of the 3 aesthetic restoration materials, where it was observed that the hybrid resin presented a greater decrease in microhardness, followed by the glass ionomer and finally the bulk resin. fill after being exposed to both carbonated beverages. It is concluded that both carbonated beverages have an important erosive effect, however, there is no statistical difference of the erosive effect between coca cola and inka cola on the 3 aesthetic restoration materials.
