Abstract
Actualmente se viene haciendo estudios sobre la capacidad remineralizante de diferentes agentes unidos a flúor, donde aquellos que contienen estaño han mostrado resultados prometedores. El presente estudio tuvo como objetivo comparar la efectividad de cuatro diferentes agentes remineralizantes en dientes permanentes. Se realizó un estudio experimental con cinco grupos(n=10), empleando la microdureza Vickers. En la pérdida de minerales participó el ácido cítrico al 1% durante un periodo de cinco días y para el proceso de ganancia de minerales participaron los agentes NaF, CPP-ACP, CPP-ACP/F, SnF2/NaF; todas expuestas en saliva artificial en un periodo de cinco días. Para hallar la efectividad remineralizante se comparó la variación de la medida de microdureza superficial pos desmineralización con la de pos remineralización. Los resultados obtenidos muestran la variación media para el grupo sometido a Fluoruro de Sodio fue de 10.00kg/mm2, 13.22 kg/mm2 para CPP-ACP, 13.60 kg/mm2 para CPP-ACP/F y 16.31 kg/mm2 para Fluoruro de estaño con Fluoruro de sodio. Se concluye que al comparar los agentes remineralizantes; NaF, CPP-ACP, CPPACP/F y SnF2/NaF, tienen fectividad diferente sobre la desmineralización con ácido cítrico sobre dientes permanentes resultando el mas efectivo el SnF2/NaF.
Studies are currently being done on the remineralizing capacity of different fluorinebound agents, where those containing tin have shown promising results. The present study aimed to compare the effectiveness of four different remineralizing agents in permanent teeth. An experimental study was conducted with five groups (n = 10), using the Vickers microhardness. In the loss of minerals 1% citric acid participated during a period of five days and for the process of mineral gain the agents NaF, CPP-ACP, CPP-ACP / F, SnF2 / NaF participated; all exposed in artificial saliva in a period of five days. To find the remineralizing effectiveness, the variation of the surface microhardness post demineralization measure was compared with that of post remineralization. The results obtained show the average variation for the group subjected to Sodium Fluoride was 10.00kg / mm2, 13.22 kg / mm2 for CPP-ACP, 13.60 kg / mm2 for CPP-ACP / F and 16.31 kg / mm2 for Tin Fluoride with sodium fluoride. It is concluded that when comparing remineralizing agents; NaF, CPP-ACP, CPPACP / F and SnF2 / NaF, have different effectiveness on demineralization with citric acid on permanent teeth, the most effective being SnF2/NaF.
