Evaluation of peroxide release during nonvital bleaching using three different coronal barriers: An in vitro study
Year: 2024
Type: article
Abstract: Background: Peroxide from bleaching agents can cause external cervical resorption. An intracoronal barrier is used to prevent leakage of bleaching agents into the periradicular space. Aim: This study aims to determine and compare the amount of peroxide released, during non vital bleaching at the end of 1 st and 3 rd day using Glass ionomer cement (GIC), Mineral Trioxide aggregate (ProRoot MTA) and Biodentine as intracoronal barriers. Materials and Methods: Forty-five single-rooted teeth were selected for the study and root canal therapy was performed. Three millimeters of the coronal gutta-percha were removed and according to the coronal barrier placed, samples were divided into Group A: GIC, Group B: ProRoot MTA, and Group C: Biodentine. Nonvital bleaching was done using sodium perborate and 30% H 2 O 2 . Peroxide released at the end of the 1 st and 3 rd day was analyzed using potassium iodide and ultraviolet spectrophotometer. Statistical Analysis: This was done using the Wilcoxon matched pair test and the Kruskal–Wallis test. Results: No significant difference in intergroup comparison at the end of 1 st and 3 rd day, respectively ( P > 0.05), a significant difference was found in the MTA group at follow-up dates ( P < 0.05). Conclusion: All the three tested materials (GIC, MTA, and Biodentine) may be preferred as intracoronal barrier for nonvital bleaching.
