Sažetak
Aim: Radiotherapy plays a key role in the treatment of the early and advanced stages of head and neck cancer. Although marked by a series of acute and late side effects that affect the cells of numerous anatomical structures in the area of the oral cavity, it also shows an impact on restorative materials. To date, there is still no consensus on the effects of radiotherapy on the mechanical properties of fluoride-releasing materials. Materials and Methods: Materials with the effect of fluoride release Equia Forte HT (GC, Japan) and Cention N (Ivoclar, Liechtenstein) were compared to resin based material Tetric EvoCeram (Ivoclar, Liechtenstein) and Tetric Power Fill (Ivoclar, Liechtenstein). Standard irradiation was performed with a linear accelerator. Vickers microhardness, mass, surface roughness and color were performed before (initial) and after irradiation.. Results: Cention N and Tetric PowerFill showed stability in the mass, while the surface roughness did not change in any of the examined groups. Resistance to microhardness change was shown by Cention N, Tetric PowerFill and Tetric EvoCeram, color change was significant in all groups (p<0.05). The brightness did not change in one group, and resistance to chromaticity changes was demonstrated by Cention N and Tetric EvoCeram. Conclusion: The obtained results suggest that Cention N can be used as material choice in patients undergoing head and neck radiotherapy due to the mechanical stability and depo effect of fluoride release. However, further research is needed.
