The effect of sonic activation combined with different chelation protocols on smear layer removal and dentin erosion: An SEM study.

Description :

A further way to improve root canal disinfection is the mechanical activation of root canal irrigants with sonic- or ultrasonic energy. Studies have shown the influence of sonic activation of irrigants on the improved cleanliness of root canals (8,9). Therefore, we aim to combine the two (Dual Rinse HEDP® with sonic activation) to evaluate a potential synergistic effect in the removal of debris, smear layer and the erosion of dentin compared to the standard protocol using sodium hypochlorite during instrumentation and the EDTA chelator in the final irrigation with or without sonic activation. In the literature, there’s a lack of a standard protocols for root canal irrigation. Therefore, we aim to provide a protocol to use while studying its benefits and potential disadvantages. The main objective: The main objective of this study would be to assess the removal of smear layer/debris/the erosion of dentin with/without the activation of Dual Rinse® HEDP and to compare the results with the most used protocol of irrigation NaOCl+ EDTA with/without sonic activation.
