Radiographic detection of overhangs formed by resin composite luting agents

Radiopacity of different resin-based and conventional luting cements compared to human and bovine teeth

“…Their use should be particularly contraindicated in situations where the margins are located in areas that have difficult access 25) . In an in-vitro study, excess cement could not be detected in association with radiopaque resin composite inlays, even with the most radiopaque materials, but they could be detected easier adjacent to radiolucent porcelain inlays 21) . The use of radiopaque resin-based luting materials is therefore especially important in combination with radiolucent restorations such as ceramic laminate veneers, inlays, onlays and fiber posts or in restorations with subgingivally located margins 18,20,22) .…”

Radiographic diagnosis of dental restoration misfit: a systematic review

“…The diagnostic tasks assessed were the detection of marginal gaps and/or overhangs adjacent to dental crowns and fillings and to abutments on implants. Twelve studies were in vitro, six dealing with the marginal fit of abutments or crowns attached to implants (38)(39)(40)(41)(42)(43), and six based on extracted teeth (44)(45)(46)(47)(48)(49), and two were in vivo studies (50,51). In vitro studies, which evaluated the diagnosis of gaps, adopted marginal discrepancies from 0.01 to 0.5 mm between restoration and tooth (45,47,48) and from 0.0127 to 0.286 mm between abutment and implant (38)(39)(40)(41)(42).…”

“…Based on QUADAS criteria analysis, none of the studies were categorised as high quality, six were of moderate quality (40,42,45,46,50,51), and eight were considered as low quality (38,39,41,43,44,(47)(48)(49). The main reasons that led one article to be classified as low quality were the lack of examiner agreement and/or any diagnostic accuracy parameters.…”

“…Accuracy parameters such as sensitivity, specificity, likelihood ratio or ROC curves were calculated in four studies . Outcomes were also evaluated using anova , qui‐square or linear regression analyses or by reporting the percentage of correctly identified defects/gaps.…”

The effects of TiO2 nanotubes on bond strength and radiopacity of a self-adhesive resin cement in self-curing mode

“…Another crucial property for limited light-curing access areas in cementation procedures is radiopacity, which plays a critical role in secondary caries diagnosis, detection of cement excess, examination of open gingival margins or marginal excesses [20,[32][33][34]. The International Organization for Standardization (ISO) for resin-modified cements requires radiopacity values equal to or greater than that of the same thickness of aluminum (ISO 9912-2:2010) [22].…”
