Assessing the Impact of Various Protective Barriers and Bleaching Agents on the Fracture Resistance of Teeth Following the Walking Bleach Technique: An in Vitro Study
Abstract: Aim: This study will aim to evaluate the effect of three different commercially available protective barriers and bleaching agents on root canal-treated teeth. Materials and Methods: Twenty-seven freshly extracted single-rooted incisors, canines, and premolars will be collected and stored in normal saline. Root canal procedures will be performed on the extracted teeth, and these will be classified into three groups with three subgroups (n=3).Group 1: Resin-modified glass ionomer cement (RMGIC) (Prevest Fusion i-Seal) will be placed at the level of the cementoenamel junction (CEJ) and cured for 30 seconds.Group 2: MTA (Prevest Denpro MTA Plus Aqua) powder and liquid will be mixed according to the manufacturer's instructions and placed at the level of the CEJ, and the mixture will be allowed to set for 1 hour. Group 3: Flowable nano-hybrid composite (G-?nial Universal Flo, GC Corporation) will be placed at the level of the CEJ. Group A will be treated with 35% carbamide peroxide. Group B will be bleached with 35% hydrogen peroxide and sodium perborate. Group C (control group) will be treated with distilled water. The bleaching procedure will be repeated once every seven days for a period of three weeks. After bleaching, each sample will be sectioned 2 mm above the level of the CEJ to remove the crown. A universal testing machine (UTM) will be used to evaluate the fracture resistance of the teeth.
