Reliability of Secondary Caries Detection Around Composite Restoration Using Light Induced Fluorescence

Reliability of Secondary Caries Detection Around Composite Restoration Using Light Induced Fluorescence in Comparison to Visual Tactile Method: Diagnostic Accuracy Study

A total of 29 volunteer patients will be assigned in this study. Each patient should have one resin composite restoration. The restoration will be evaluated by two diagnostic methods (D), where D1 represents visual-tactile assessment method (modified USPHS) and D2 represents light induced fluorescence intraoral camera

Three operators, the researcher and the 2 supervisors, from the Conservative Dentistry Department, Faculty of Dentistry, Cairo University, will be the examiners in this study. Each examiner will record the dental findings using both the visual- tactile assessment method and the fluorescent-aided identification method. The visual-tactile assessment method includes the use of mirror, probe under good illumination condition, while the fluorescent-aided identification method will be performed by light induced fluorescence intraoral camera

Inclusion Criteria:

• Patients should be over 18 years of age. Patients should have an acceptable oral hygiene level. Patients must have at least one posterior resin composite restoration

Exclusion Criteria:

Patients with a compromised medical history. Severe or active periodontal disease. Heavy bruxism or a traumatic occlusion.
