ABSTRACT

PURPOSE:

To evaluate the ability sealing of glass ionomer and composite resin with or without 1-mm thickness of Coltosol on the root-canal filling material.

METHODS:

Root-canal treatment was completed on 50-extracted human mandibular unirradicular. The teeth were divided into six groups G1, positive control; G2, negative control; G3, glass ionomer (Vidrion R); G4, Coltosol + Vidrion R; G5, composite resin; and, G6, Coltosol + composite resin. For G1 and G2 five teeth each were used and for the other groups, ten teeth each. The teeth were thermocycled and evaluated for microleakage using methylene blue dye. Specimens were sectioned and measurements made to the maximum point of dye penetration. The mean dye penetration (%) for each group was compared by ANOVA and Tukey's test for post-hoc comparisons (α=0.05).

RESULTS:

The means and standard deviations of microleakage were G1, 96.56 (±2.31); G2, 0.00 (±0.00); G3, 68.76 (±24.63); G4, 24.42 (±8.33); G5, 20.06 (±9.35); and, G6, 12.86 (±6.08).

CONCLUSION:

It was concluded that none of the materials were able to prevent microleakage. Composite resin alone or combined with coltosol and glass ionomer associated with coltosol resulted in less microleakage than the glass ionomer used alone.
RESUMO

OBJETIVOS:

Avaliar a capacidade de selamento do ionomero de vidro e resina composta, com ou sem 1 mm de coltosol, sobre o material obturador endodôntico.

MÉTODOS:

O tratamento endodôntico foi realizado em 50 dentes humanos mandibulares unirradiculares. Os dentes foram divididos em 6 grupos G1, controle positivo; G2, controle negativo; G3, ionômero de vidro (Vidrion R); G4, Coltosol + Vidrion R; G5, resina composta; e, G6, Coltosol + resina composta. Os dentes foram submetidos a termociclagem e a avaliação da microinfiltração usando azul de metileno. Os especimes foram seccionados e a quantidade maxima de penetração de corante avaliado. As medias e desvios-padrão de penetração do corante (em %) para cada grupo foram analisadas pelo teste ANOVA e pelo teste de multiplas comparações de Tukey's (α=0.05).

RESULTADOS:

As medias e desvios-padrão de midroinfiltração foram G1 96,56 (±2,31); G2 0,00 (±0,00); G3 68,76 (±24,63); G4 24,42 (±8,33); G5 20,06 (±9,35); and,G6 12,86 (±6,08).

CONCLUSÃO:

Pode-se concluir que nenhum material obturador preveniu completamente a microinfiltração. Resina composta utilizada isoladamente ou associada ao coltosol e o ionômero de vidro associado ao coltosol apresentaram menor microinfiltração do que o ionomero de vidro utilizado sozinho.
