Abstract:
Objective:
To analyze the mineral composition of enamel after a whitening treatment using hydrogen peroxide at 35% (HP) and a subsequent recovery treatment with desensitizing gel containing potassium nitrate at 3% and sodium fluoride at 0.25%, using the LIBS technique.
Study design:
Thirteen healthy premolars were exposed to in vitro tooth whitening using HP at 35% (WhiteGold, Dentsply, USA) and subsequently treated with a desensitizing gel containing potassium nitrate at 3% and sodium fluoride at 0.25% (UltraEZ, Ultradent, South Jordan, UT, USA) to assess the recovery of mineral content lost because of the treatment with HP. The content of Ca, Mg, Na, C and CaF was repeatedly evaluated using laser-induced breakdown spectroscopy of the control enamel (M1), enamel exposed to HP (M2), enamel treated with potassium nitrate and sodium fluoride at 24 hours (M3), 7 days (M4) and 14 days (M5) after whitening.
Results:
The presence of elements like Ca, Mg, Na, C and the compound CaF, was detected, proving there is no mineral recovery after applying potassium nitrate at 3% and sodium fluoride at 0.25%.
Conclusions:
The use of a desensitizing gel containing potassium nitrate at 3% and sodium fluoride at 0.25% does not recover the mineral content of the enamel treated with HP at 35% The LIBS technique allowed to verify the presence of elements such as Ca, Mg, Na, C and the compound CaF, as well as the temporal modifications of their proportions in enamel.
