Resumen
Los agentes cementantes duales aparecieron con la finalidad de
mejorar las propiedades favorables de los cementos fotoactivados y
convencionales, sin embargo si la foto polimerización no es
adecuada en los cementos duales disminuirá sus propiedades,
posibilitando su fracaso. En este sentido, se describirá con base en
la literatura, los diferentes tipos de cementos resinosos,
propiedades, clasificación, microfiltración y desajustes cavitarios. El
propósito del presente trabajo es hacer una revisión bibliográfica
crítica acerca de la necesidad de foto activación de los cementos
resinosos. En la actualidad resulta complejo recomendar un material
con respecto a otro para todas las situaciones clínicas, es el deseo
de los odontólogos poder contar con un material universal, que
actúe de igual manera sobre todos los tejidos dentales. A pesar del
avance vertiginoso de los cementos duales, estos aún no pueden
sustituir a los cementos resinosos que utilizan el grabado total,
debido a la incompleta integración de estos a los tejidos dentarios.
La composición de los cementos autoadhesivos a base de
monómeros ácidos, no permite penetrar el barrillo dentinario ni
desmineralizar la encía remanente, impidiendo su total penetración
en los túbulos dentinarios y generar mayor adhesión. La conclusión
a la que se ha llegado es que no existe diferencia significativa entre
ambos cementos resinosos
Dual cementing agents appeared in order to improve the favorable properties of conventional cements photoactivated, however if the photo polymerization is not suitable in dual cements it will decrease their properties, enabling their failure. In this sense, it’ll be described based on the literature, different types of resin cements, properties, classification, microfiltration and cavitary mismatches. The purpose of this assingment is to make a bibliographic research about the need of photo activation for resin cements. Today is complex to recommend an item over another for all clinical situations, it is the desire of dentists to have a universal material, acting equally on all dental tissues. Despite the rapid advance of the dual cements, these can not yet replace resin cements using the total engraving, due to the incomplete incorporation of these to the dental tissues. The composition of the adhesive cements based on acid monomers can not penetrate the smear layer and demineralizing the remaining gum, preventing its full penetration in the dentinal tubules and generate greater adhesion. The final conclusion is that there is no significant difference between the two resin cements.
