So, the purpose of this study was to evaluate the radiopacity of six root canal sealers at different focal distances. Materials and Methods: In this in vitro study, six endodontic sealers (ADSEAL, AH26, AH plus, Dorifill, MTA fillapex, and ZOE), were prepared and placed in a mold with 1mm thickness and 10mm diameter. The specimens were posi-tioned alongside an aluminum step wedge on a digital detector (occlusal size 76×57 mm). Radi-ographic imaging was performed at 15 and 30cm focal distances and radiopacity of each specimen was measured.One-way ANOVA and paired t-test were used and p SP - 23 EP - 27 AU - Ehsani, Maryam AU - Abesi, Farida AU - Haghanifar, Sina AU - Khafri, Sorayya AU - Hamzeh, Mahtab AU - Habibi, Ayub AD - Dental Material Research Center, Department of endodontics, Babol University of Medical Sciences, Babol, Iran KW - Endodontic KW - Digital KW - Radiography UR - http://3dj.gums.ac.ir/article-1-46-en.html DO - 10.18869/acadpub.3dj.2.2.23 ER -
