Resumen
Objetivo

El objetivo de este estudio fue determinar las diferencias de microfiltración, en dientes humanos extraídos, entre la aplicación de un sellante en base a resina con una técnica de grabado ácido convencional y un sellante en base a resina autograbante.

Material y método

Un total de 40 molares y premolares intactos fueron separados de manera randomizada en dos grupos de sellantes de fotopolimerización: Sellante autograbante Enamel Loc™ (Premier) (Grupo 1, n=20) y Concise™ White Sealant utilizando una técnica de grabado ácido convencional (3M™ ESPE™) (Grupo 2, n=20). Antes de ser termociclados (x100, 15-7 grados Celcius) se impermiabilizaron las superficies dentarias a excepción de la cara oclusal. Posteriormente se sumergieron las muestras en una solución de nitrato de plata al 50% por 24 horas, luego fueron expuestas a una solución reveladora de radiografías (Kodak GBX) y finalmente desgastadas hasta el centro de la fisura. Las fotografías, obtenidas mediante un estereomicroscopio, fueron evaluadas por dos examinadores calibrados (kappa=0,95).

Resultados

Se observaron diferencias estadísticamente significativas (p<0,0001) entre ambos grupos.

Conclusión

El sellante de autograbado Enamel Loc™ mostró valores más altos de microfilatración.

Palabras clave:
Sellantes

Abstract
Purpose

The purpose of this study was to examine differences in microleakage in extracted human teeth when placing sealants using conventional acid etching or a self-etching fissure sealant.

Methods

A total of 40 intact molars and premolars were randomly assigned to one of two light-cured sealant groups: self-etching fissure sealant Enamel Loc™ (Premier)(Group 1, n=20) and Concise™ White Sealant using conventional acid etching (3M™ ESPE™) (Group 2, n=20). Before thermocycling (x100, 15-7 degrees C) all teeth surfaces were made impermeable with the exception of the occlusal surface. Samples were immersed in 50% silver nitrate for 24 hours, then immersed in Rx development solution (Kodak GBX) and after abrassioned longitudinally until central fissure pit. Pictures were obtained by light microscope and the presence of microleakage was evaluated by two calibrated evaluators (kappa= 0,95).

Results

Significant statistical differences (p<0,0001) were observed between groups.

Conclusions

Self-etching fissure sealant Enamel Loc™ showed higher microleakage scores.
