Resumo: Purpose: This study aimed to evaluate the radiopacity of some endodontic sealers using a digital radiograph system. Methods: The endodontic sealers tested were: AH-Plus, N-Rickert, Endofill, Óxido de zinco e eugenol (OZE), and Intrafill. Six cylindrical-shaped specimens (1x0.5cm) were fabricated with each material and stored at 37ºC and 100% relative humidity for 72h. Each specimen was placed at the central area of the sensor of the digital system Kodak RVG 5000, and the X-ray cylinder was positioned perpendicularly at a 5cm-focal distance with time of exposure of 0.05s. The digital image software was used to measure optical density in pixels of the specimens at their central area and at the right and left sides. Data were analyzed by ANOVA and Tukey test (α=0.05). Results: There was a statistically significant difference of radiopacity among the tested materials, except for the comparison between Intrafill and Endofill. The level of radiopacity in ascending order was: ZOE < Endofill = Intrafill < N-Rickert < AH-Plus. Conclusion: The digital radiograph method was sensitive to detect differences of radiopacity among the tested endodontic sealers. Key words: Endodontics; endodontic sealers; radiopacity

Metodologia: Foram testados os cimentos endodônticos AH-Plus, N-Rickert, Endofill, Óxido de zinco e eugenol (OZE) e Intrafill. Seis corpos-de-prova cilídricos (1x0,5cm) para cada cimento foram confeccionados e armazenados a 37ºC e umidade relativa de 100%, durante 72h. Os corpos-de-prova foram posicionados na região central do sensor do sistema digital Kodak RVG 5000 e o cilindro do aparelho radiográfico foi posicionado perpendicularmente a uma distância focal de 5cm, com tempo de exposição de 0,05 segundos. A partir da imagem digital obtiveram-se os valores da densidade óptica em pixels da região central e pontos eqüidistantes à direita e à esquerda de cada corpo-de-prova. Os dados foram analisados por ANOVA e teste de Tukey (α=0,05). Resultados: Houve diferença estatística entre todos os cimentos, com exceção da comparação entre o Intrafill e o Endofill. A radiopacidade dos cimentos em ordem crescente foi: ZOE < Endofill = Intrafill < N-Rickert < AH-Plus. Conclusão: O método de radiografia digital foi sensível para detectar diferenças de radiopacidade entre os cimentos endodônticos analisados.
