Aim of the study : The aim of this study was to assess the reliability and reproducibility of secondary caries diagnosis using light induced fluorescence device 2Soprolife3 in comparison to conventional visual-tactile method according to modified USPHS restoration assessment Methodology : A total of 29 volunteer patients were assigned in this study. Each patient had at least one defected posterior occlusal resin composite restoration. The restoration was evaluated by two diagnostic methods; the visual tactile examination and assessment using the modified USPHS criteria and the light fluorescence device SOPROLIFE (SOPRO, ACTEON Group, La Ciotat, France). This method involves an intraoral LED light-emitting diode camera offering the ability to detect and locate differences in density, structures, and/or chemical composition of hard tooth tissues.The blue LED, selected by the device, emits at a 450 nm-wavelength which excites a light fluorescence signal re-transmitted by dentine. The spectrum of the fluorescence signal is green when the dentine is healthy and dark red when the dentine is infected (according to the SOPROLIFE manufacturers instructions). According to modified United States Public Health Service USPHS/ Ryge criteria Direct Clinical Evaluation of Restoration , which states the use of an eye without any magnification device, only a dental mirror and an explorer, in a proper isolated field following the directions to assess secondary caries existence. Prior to the initiation of the study, calibration sessions were arranged for the 3 operators using the two methods separately in the examination site
