dc.description.abstractObjective: The purpose of the present study was the in vitro pH and solubility of an experimental cement based on zinc oxide, Portland cement and dolomite clay with other cements commonly used as temporary restoration in endodontics Ketac™ Molar Easymix, Zinc Oxide Eugenol, Clip F and Coltosol® F. Materials and methods: One hundred ten polyethylene tubes were filled with the cements corresponding to the 5 groups (n = 22). Fifty-five of these samples were immersed in 10 ml of distilled water and incubated at 37 ° C. The pH was determined with a digital pH meter after one day and the 3, 7, 14, 21 and 28 days of immersion were determined. In addition, the initial weight of 55 samples were recorded, immersed in artificial saliva at pH 7 and incubated at 37 ° C for 7 days. After this period the samples were dried, stored in a desiccator containing anhydrous calcium sulfate for 60 min and weighed. Data were analyzed using ANOVA and Student’s t-test (P <0.05). Results: Experimental cement showed alkaline values in all periods evaluated and significantly different from other materials (p <0.005). As for the solubility study, only the significant difference in Coltosol and experimental cement was found, there being a lower solubility after 7 days in the Coltosol® F followed by the experimental cement, Ketac™ Molar Easymix, Zinc Oxide Eugenol and Clip F. Conclusion: Experimental cement based on zinc oxide, Portland cement and clay dolomite showed alkalinity and low solubility, properties sought in a temporary restoration material in endodontics.

html.description.abstractObjetivo: Evaluar y comparar in vitro el pH y la solubilidad de un material experimental a base de óxido de zinc, cemento Portland y arcilla dolomita con otros materiales de restauración temporal comúnmente usados en endodoncia: Ketac™ Molar Easymix, Óxido de Zinc y Eugenol, Clip F y Coltosol® F. Materiales y Métodos: Los materiales de restauración temporal fueron colocados en 110 tubos de polietileno correspondientes a los 10 grupos (n=11) propuestos para este estudio. 55 de estas muestras fueron inmersas en 10 ml de agua destilada e incubadas a 37º C. Se determinó el nivel de pH con un pH-metro digital luego de un día y a los 3, 7, 14, 21 y 28 días de inmersión. Además, se registró el peso inicial de 55 muestras, las cuales fueron sumergidas en 10 ml de saliva artificial e incubadas a 37º C por 7 días. Luego de este periodo las muestras fueron secadas, almacenadas en un desecador que contiene sulfato de calcio anhidro por 60 min. y pesadas nuevamente. Los datos fueron analizados usando la prueba de ANOVA y t de Student (p< 0.05). Resultados: El cemento experimental mostró valores alcalinos en todos los periodos evaluados y significativamente diferente a los demás materiales (p<0.005). En cuanto al estudio de solubilidad solo se encontró diferencia significativa en el Coltosol® F y el cemento experimental, existiendo una menor solubilidad luego de 7 días en el Coltosol® F seguido del cemento experimental, Ketac™ Molar Easymix, Óxido de Zinc y Eugenol, Clip F. Conclusiones: El cemento experimental a base de óxido de zinc, cemento Portland y arcilla dolomita, mostró alcalinidad y baja solubilidad con respecto a los demás materiales, propiedades buscadas en un material de restauración temporal en endodoncia.
