Influence of different cavity disinfection solutions and laser systems on repair bond strength of silorane based composite

Purpose: Evaluating effects of Nd:YAG-laser, Er:YAG-laser, chlorhexidine and ozonated water application which is used for purpose antibacterial effects, on repair bond strength silorane based composite. Materials Methods: 100 cavities (2 mm deep, 3 diameter) prepared in acrylic blocks were filled with composite subjected thermal cycle divided into 5 groups (N=20). Group 1:Chlorhexidine; 2:Ozonated-water; 3:Nd:YAG-laser; 4:Er:YAG-laser; (control): untreated. Composite procedure was implemented the same Groups 2 subgroups (n=10). One each group second cycle. All samples tested by a universal test device. Data analyzed statistically significance difference between two means (Kolmogorov-Simirnov), variance analysis, Student-t Test used. Results: No statistical observed among after first (p>0,05). After repair, there no significant that to When evaluated themselves comparing before operation; as Ozonated-water, Nd:YAG, Er:YAG Control (p>0,05), decrease only Chlorhexidine (p<0.05). Conclusion: Nd:YAG-laser Er:YAG-laser applications can be silorane-based restorations an alternative application, since reduces bonding strength.
