Effect of Different Fluoridation Regimes on the Microhardness of Bleached Enamel

Abstract

Effect of Different Fluoridation Regimes on the Microhardness of Bleached Enamel Clinical RelevanceFluoridation is effective in preventing microhardness loss due to bleaching, but additional fluoride gel supplementation is not superior to toothpaste fluoridation alone.

Effect of home bleaching systems on enamel nanohardness and elastic modulus

“…30,47 The regular clinical application of fluoride-containing tooth pastes were found to be sufficiently effective to avoid loss of enamel microhardness during bleaching, without the need for supplemental fluoride gel treatments. 52 It is particularly interesting to note that the use of Whitestrips was found to cause significantly lower enamel demineralization compared to other bleaching products. 53 The authors attempted to simulate the oral conditions as far as was applicable in the study design.…”

Effects of Tooth Coating Material and Finishing Agent on Bleached Enamel Surfaces by KTP Laser

“…15,16) Due to the disadvantage of bleaching, the fluoride gel and finishing agent were applied on the surfaces of enamel. [4][5][6] Kameda A et al …”

“…3) After bleaching, fluoride gel was applied for remineralization, but the additional supplementation of fluoride gel did not enhance the microhardness. 4) Recently the effect of finishing agent was reported, 5) and nano-hydroxyapatite was one of the finishing agents and effectively reduced the negative effects of a bleaching agent on enamel surfaces; surface roughness and gloss values. 5,6) The bleached enamel surfaces applied with fluoride gel and finishing agent are soon exposed the various matters such as saliva, food and many kinds of beverages.…”

Effect of CPP-ACP Application on Flexural Strength of Bleached Enamel and Dentin Complex

“…13 Human saliva not only has buffering properties and prevents demineralization, it is also rich in calcium and phosphate and acts as a source of remineralization after bleaching procedures. 39 Therefore, it is recommended that similar studies with storage in saliva and replenishing saliva between sessions be carried out.…”
