Abstract (english)

To examine the effect of ionizing radiation on fluoride release from restorative dental materials, samples of Equia Forte HT, Fuji Triage, Fuji IX, Cention Forte, Activa Presto, Beautifil II, and Luminos (n = 10) were made in Teflon molds and divided into a control group and an experimental group. The experimental group was exposed to ionizing radiation for a total of 35 days (70 Gy, 2 Gy per day). The fluoride release was measured with a fluorine-selective electrode. The median recorded fluoride values were higher with Equia Forte HT, Fuji Triage, and Fuji IX compared to others during the entire period in both groups. With Activa Presto, a higher release of fluoride was recorded in the experimental group on the first day of irradiation, while a higher release was recorded in the control group, as well as with Luminos and Beautifil II. With Cention Forte, there was no significant difference in fluoride release between the experimental and control groups except on the sixth day. With Fuji Triage and Fuji IX, the release of fluoride was higher in the experimental group compared to the control group, while with Equia Forte HT, there was no difference between the groups. In conclusion, ionizing radiation has no major effect on fluoride release in all the tested materials.
