Clinical Evaluation and Microbiological Assessment of Diode Laser and Chemical Disinfection in Comparison to Selective Caries Removal

Objectives: To evaluate the clinical and antimicrobial effect of Diode laser and chemical disinfection in comparison to selective caries removal in management of deep carious lesions. Methods: This study will be carried on 30 patients with an age range of 18 -50 years. The patients will be selected from the outpatient clinics in Faculty of Oral and Dental Medicine, Misr International University. All patients will be randomly divided into 3 equal groups; Control group, Diode laser application with an output power of 0.5 watt group, and Chemical disinfection group. Preoperative clinical assessment and radiographs will be performed before intervention and then the patients will receive their treatment and final restorations. Follow-up with clinical assessments will be performed after 3 and 6 months. Cone beam computed tomography will be performed at the day of intervention and after 6 months. Clinical, Microbiological and Radiographic data will be collected, tabulated and statistically analyzed to compare between the success rates of diode laser, chemical disinfection and conventional selective caries removal.
