Abstract EN
The aim of this study was to assess the effect of radiotherapy on bond efficiency of two different adhesive systems using tensile bond strength test.
Twenty extracted teeth after radiotherapy and twenty nonirradiated extracted teeth were used.
The irradiation was applied in vivo to a minimal dose of 50 Gy.
The specimens of each group were randomly assigned to two subgroups to test two different adhesive systems.
A three-step/etch-and-rinse adhesive system (Optibond FL) and a two-steps/self-etch adhesive system (Optibond XTR) were used.
Composite buildups were performed with a nanohybrid composite (Herculite XTR).
All specimens were submitted to thermocycling ageing (10000 cycles).
The specimens were sectioned in 1 mm2 sticks.
Microtensile bond strength tests were measured.
Nonparametric statistical analyses were performed due to nonnormality of data.
Optibond XTR on irradiated and nonirradiated teeth did not show any significant differences.
However, Optibond FL bond strength was more effective on nonirradiated teeth than on irradiated teeth.
Within the limitations of an in vitro study, it can be concluded that radiotherapy had a significant detrimental effect on bond strength to human dentin.
However, it seems that adhesive choice could be adapted to the substrata.
According to the present study, the two-steps/self-etch (Optibond XTR) adhesive system tested could be more effective on irradiated dentin compared to three-steps/etch-and-rinse adhesive system (Optibond FL).
