PURPOSE: To evaluate the radiopacity produced by seven commercially available (AH Plus, Epiphany, Sealapex, Acroseal, Sealer 26, Endomethasone and Endofill) and one experimental (MBP) root canal sealers. METHODS: Sealer radiopacity testing was performed according to ANSI/ADA Specification No. 57. Specimens were radiographed with an aluminum stepwedge, and the resulting images were digitalized. Radiographic densities expressed in Aluminum mm (mm Al) were compared using an ANOVA and Tukey's test (α=0.05). RESULTS: AH Plus (10 mm Al) and Epiphany (9.0 mm Al) were the most radiopaque root canal sealers, followed by Sealapex (8 mm Al), Endofill (7 mm Al), Endomethasone (7 mm Al), MBP (7 mm Al) and Sealer 26 (6 mm Al). Acroseal (5 mm Al) showed the smallest radiopacity among the tested sealers (P<0.05). CONCLUSION: The radiopacities of the tested sealers were above the minimum level recommended by ANSI/ADA Specification No. 57.

OBJETIVO: Avaliar a radiopacidade produzida por sete cimentos comercialmente disponíveis (AH Plus, Epiphany, Sealapex, Acroseal, Sealer 26, Endomethasone and Endofill) e um em estágio experimental (MBP). METODOLOGIA: Depois de homogeneizados os materiais, o teste de radiopacidade foi executado conforme a especificação nº 57 da ANSI/ADA. Radiografou-se os espécimes junto a uma escala de Alumínio e as imagens resultantes foram digitalizadas. As densidades radiográficas expressas em milímetros de Alumínio (mm Al) foram comparadas por meio da análise de variância e teste de Tukey (α=0.05). RESULTADOS: Os cimentos AH Plus (10 mm Al) e Epiphany (9 mm Al) apresentaram as maiores radiopacidades seguidos pelo Sealapex (8 mm Al), Endofill (7 mm Al), Endométhasone (7 mm Al), MBP (7 mm Al) e Sealer 26 (6 mm Al). Acroseal (5 mm Al) mostrou a menor radiopacidade entre os cimentos testados (P<0.05). CONCLUSÃO: Concluiu-se que as diferentes radiopacidades dos cimentos testados estão acima do nível mínimo recomendado pela especificação nº 57 da ANSI/ADA.
