Online Article: Radiopacity of Luting Cements as a Potential Factor in Peri-implantitis: An In Vitro Comparative Study

The aim of this study was to establish the radiopacity of cements used in implantretained fixed partial dentures with respect to implant material, enamel, and dentin. A sample of 10 specimens of 13 different cements, implants, enamel, and dentin were prepared. Radiographs of the specimens and aluminum step wedges were acquired. Mean gray values of specimens were measured using digital imaging software. Kolmogorov-Smirnov and Shapiro-Wilk normality tests and independent t test were used (P = .05). Implantlink Semi, Premier, and Dentotemp had the lowest radiopacity values; GC FujiTemp LT, Multilink Implant, Poly-F Plus, Cavex-Temporary, and Panavia SA showed the highest. Within the limitations of the study, cements containing zinc oxide and ytterbium-trifluoride can be recommended for cementation of implant-retained restorations.
