“…The ideal root canal sealer should present, among other physical/chemical properties, enough radiopacity to allow distinction from the adjacent anatomical structures 2,11,14,10 , such as bone and tooth 13 . Higginbotham 7 (1967) was the first researcher to publish a study comparing the radiopacity of various endodontic sealers and gutta-percha cones used to fill root canals 7 .…”

he aim of this study was to evaluate the radiopacity of a zinc oxide and eugenol-based (Endofill), a calcium hydroxidebased (Sealapex), two resin-based (Sealer 26 and AH Plus), and a silicone-based root canal sealer (Roeko Seal). Specimens, measuring 10mm in diameter and 1mm in thickness, were radiographed simultaneously with an aluminum step wedge using occlusal films, according to ISO 6876/2001 standards. Radiographs were digitized, and the radiopacity of sealers was compared to the different thicknesses of the aluminum step wedge, using the VIXWIN 2000 software. Results demonstrated that AH Plus was the most radiopaque sealer, while Sealapex was the least radiopaque (p<0.05). Roeko Seal, Endofill and Sealer 26 presented intermediate radiopacity values. Sealapex presented less radiopacity than the other types of root canal sealers.

Os corpos de prova foram padronizados com 10 milímetros de diâmetro e 1 milímetro de espessura e radiografados conjuntamente com uma escala de alumínio empregando-se filmes oclusais, de acordo com as Normas ISO 6876/2001. As radiografias foram digitalizadas e as radiopacidades dos cimentos comparadas à escala de alumínio com diferentes espessuras, utilizando o software VIXWIN 2000. Os resultados demonstraram que o AH Plus foi o cimento mais radiopaco e o Sealapex apresentou menor radiopacidade (p<0,05), sendo intermediários os resultados para os cimentos Roeko Seal, Endofill e Sealer 26. Sealapex apresenta menor radiopacidade que outros tipos de cimentos endodônticos. Unitermos: Material obturador de canal radicular; Radiopacidade.

“…Radiopacity of an endodontic material provides a contrast between adjacent anatomical structures and filling material; and it improves the radiographic diagnosis of voids and improper contours (14,19). The molecular structure and the thickness of a material have a major effect on the radiopacity.…”

Methods: The root-canal filling materials tested were MTA Fillapex, Adseal, AH Plus, Endomethasone and gutta-percha cones. Standard disks of five different root-canal filling materials were exposed together with an aluminum stepwedge calibrated in millimeters. For the radiographic exposures, a storage phosphor plate (size 4; 5.7x7.6 cm) and an x-ray machine at 70 kVp and 8 mA were used. The object-tofocus distance was 30 cm, and the exposure time was 0.2 sec. The grey values of the test materials were measured digitally using the system's own software and compared with the stepwedge to find the equivalent thickness of aluminum. The data were analyzed statistically with significance levels set at p<0.05. Results:The radiopacity values of the studied materials in decreasing order, expressed in millimeters of aluminum equivalent, were: AH Plus (9.70), gutta-percha (6.82), MTA Fillapex (5.30), Adseal (3.71) and Endomethasone (3.67). Statistically significant differences were found between mean radiographic density values of the tested materials (p<0.005), AH Plus showing the highest value.
