“…This result is likely due to differences in the radiopacity potential of specific components, similar as the effects observed when bismuth oxide (present in Epiphany) and zirconium oxide (present in AH Plus) are added individually to pure Portland cement (16). When evaluating zinc-oxide eugenol sealers, the powder/ liquid ratio chosen directly influenced the in vitro radiopacity (18). Because manufacturers do not explicitly state the correct powder/liquid ratio, the larger amounts of Endomethasone and Endofill powder added to liquids may explain the radiopacity differences in this research compared to others (9,10,13,19).…”

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.Key words: Radiopacity; root canal filling; digital radiography; sealer ResumoObjetivo: 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 n o 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.

“…Estimation of pH of ZOE and antibiotic combination was done according to formulation-1gm of ZnO powder and 0.5 ml of eugenol [14]. Sealer samples were prepared by adding 10gms of zinc oxide powder to 5ml of eugenol and were freshly mixed which was minimum required quantity for immersion of pH electrode of pH meter (ELICO pH METER L1 120 DIGITAL).…”

“…In the present study freshly mixed Diaket was placed directly into the tissue [26,27].At the end of 30 days, histopathological observation exhibited chronic inflammatory reaction with mild amount of necrosis and foreign body reaction. The cytotoxicity did not decrease proportional to their setting time as does that of zinc oxide eugenol based sealer tested under the same parameter [28,29,].Therefore the possibility that these type of sealers could irritate periapical tissue for a longer period of time should be considered [30,31]Inflammatory reactions associated with seal apex is in equal magnitude as that of other sealers in the initial stage [32,33,34],but by around 10 th day inflammatory cells subsided drastically and a healing potential has become active by around 30 days [35,36].…”
