Eficacia de la obturación ortógrada de conductos radiculares con MTA vs. MTA más conos de gutapercha

Abstract

Objetivo: Evaluar la capacidad del sellado del MTA usado como material único de sellado o usándolo como cemento sellador más conos de gutapercha. Materiales y métodos: Se seleccionaron las raíces mesiales de 24 molares inferiores y se instrumentaron hasta una lima maestra apical # 40 con la técnica de Crown Down. El grupo I fue obturado con conos de gutapercha y el MTA fue usado como cemento sellador; el grupo II fue obturado con MTA solamente. Se utilizaron cuatro raíces como control positivo y negativo; las muestras fueron cubiertas con cera pegajosa, dejando libre solo los dos últimos milímetros apicales, se centrifugaron en tinta china durante una hora y se les realizó procedimiento de transparentación, para posteriormente medir la microfiltración con un microscopio estereoscópico. Resultados: Los resultados fueron analizados estadísticamente con el test de KRUSKAL-WALLIS para variables independientes, y no se encontró diferencia estadísticamente significativa entre los dos grupos. Conclusiones: No se encontró diferencia estadísticamente significativa entre los dos grupos. En situaciones clínicas que no permiten la obturación convencional con conos de gutapercha, cualquiera de las dos técnicas de colocación del MTA son factibles.
