Abstract

Purpose: This study was conducted to investigate the fracture strength of reattached tooth fragments after different cavity disinfection protocols.

Materials 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 (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 (p<0.05), with the highest bond strength detected in the NaOCl+Asc Group (148.22 ± 51.64) and the lowest in the NaOCl Group (112.84 ± 43.12). Scotchbond Universal exhibited the highest bond strength values (163.59 ± 49.94); however, there were no significant differences between the other adhesive systems (p> 0.05).

Conclusion: Application of ascorbic acid following sodium hypochlorite treatment can improve dentin bond strength.

Keywords: Cavity disinfectants; crown fracture; reattachment; universal adhesives.
