Abstract :Purpose: This study was conducted to investigate the fracture strength of reattached tooth fragments after different cavity disinfection protocols. Material and Methods: Incisal edges of 144 bovine incisors were sectioned and then randomly divided into 4 different groups as follows: Group C: no disinfectant; Group NaOCl: 2.5% sodium hypochlorite solution; Group NaOCl+Asc: 2.5% sodium hypochlorite followed by 10% ascorbic acid solution; Group CHX: 2% chlorhexidine solution. Teeth were further divided into 3 subgroups according to universal adhesive insert ignore into journalissuearticles values(G-Premio Bond, Scotchbond Universal, Prime and Bond Universal);. Fracture resistance was evaluated using a universal testing machine. Data was analyzed using 2-way ANOVA with Bonferroni tests. Results: Cavity disinfectant had a statistically significant effect on bond strength insert ignore into journalissuearticles values(p<0.05);, with the highest bond strength detected in the NaOCl+Asc Group insert ignore into journalissuearticles values(148.22 ± 51.64); and the lowest in the NaOCl Group insert ignore into journalissuearticles values(112.84 ± 43.12);. Scotchbond Universal exhibited the highest bond strength values insert ignore into journalissuearticles values(163.59 ± 49.94);; however, there were no significant differences between the other adhesive systems insert ignore into journalissuearticles values(p> 0.05);. Conclusions: Application of ascorbic acid following sodium hypochlorite treatment can improve dentin bond strength.
