Effects of Various Chelating Agents in Combination with Sodium Hypochlorite on Root Fracture Toughness of Endodontically Treated Teeth after Ultrasonic Activation: An In-Vitro Study
Year: 2025
Type: article
Abstract: Background and Objective: Various chelating compounds in combination with sodium hypochlorite were tested for their effects on root fracture toughness of ultrasonically activated endodontically treated teeth. Materials and Methods: Based on irrigant combination, 50 extracted lower premolar teeth were randomly assigned to five groups of 10. Group 1 (negative control), Group 2 (positive control), Group 3 (3% sodium hypochlorite [NaOCl] +17% ethylenediaminetetraacetic acid), Group 4 (3% NaOCl + 18% etidronic acid), and Group 5 (3% NaOCl + 10% citric acid). Ultrasound is used to activate irrigants. The obturated samples were tested using a universal testing machine for root fracture toughness. Results: It was found that endodontic treatment decreased root fracture toughness. Additionally, chelating agents reduce fracture resistance. This study found that 10% citric acid has the least effect on root dentin fracture resistance. Conclusion: Irrigation with various chelating agents and sodium hypochlorite reduces endodontic tooth fracture resistance. Citric acid was the most effective against fractures.
