Background: Successful regeneration depends on four key elements of tissue engineering such as stem cells, growth factors, scaffold and sterile environment. Therefore, regenerative endodontic therapy requires higher degree of disinfection for successful outcomes. Aims and Objective: To evaluate the clinical and radiographic outcome using conventional and laser assisted disinfection in regenerative endodontics at 1, 3 and 6 months. Materials and Methods: 18 children with necrotic young permanent teeth were selected for the study. In Group A, in the first appointment AAE (American Association of Endodontics, Clinical Consideration for Regenerative Endodontic Procedure - 2016) disinfection protocol was employed. In Group B laser assisted disinfection (810 nm diode laser, 1 W, 20 ms Pulse length and 20 ms interval duration) was performed. Microbial samples were obtained before and after disinfection to check the level of disinfection. The cases were followed up at 1 month, 3 months and 6 months interval and evaluated for clinical outcome, periapical healing and apical response. Data were statistically analyzed with level of significance set 1% or 5% accordingly (P |
