Each patient should have at least one resin composite restoration. The restoration will be evaluated by all diagnostic methods. Each examiner will independently record the dental findings using all methods, the visual- tactile assessment method and both fluorescent-aided identification methods. The visual-tactile assessment method includes the use of mirror, probe under good illumination condition, while the fluorescent-aided identification methods will be performed by both light-induced fluorescence intraoral camera and laser-induced fluorescence device. Then Diagnostic performance for caries detection was evaluated, assessing the validity of each diagnostic method in diagnosing secondary caries around margins of resin composite restorations
This study will be conducted to evaluate the clinical performance and validity of both light-induced fluorescence intraoral camera and laser-induced fluorescence device in comparison to visual-tactile assessment method in detection of secondary caries around margins of resin composite restorations.
