Fluoride application showed that a thick layer covered the surface but no difference was seen between two application times. in conclusion; as the enamel exposed to bleaching agents showed severe morphologic surface alterations, fluoride application on the bleached enamel could help to protect the enamel.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Objective of this study was to evaluate the effect of bleaching agents (hydrogen peroxide, hydrochloric acid and ether) on enamel and also the effect of fluoride application (APF) to bleached enamel.
📊
Key Findings & Data:The other specimens were covered with an acid resistant varnish except labial/lingual surfaces and freshly prepared bleaching solution was applied for one hour at 37°C. in groups 3 and 4, APF gel was applied either 2 or 4 minutes.

Abstract

Objective of this study was to evaluate the effect of bleaching agents (hydrogen peroxide, hydrochloric acid and ether) on enamel and also the effect of fluoride application (APF) to bleached enamel. Four freshly extracted third molar teeth were divided into four pieces by cutting them mesiodistally and buccolingually. One part ofeach teeth was used as control. The other specimens were covered with an acid resistant varnish except labial/lingual surfaces and freshly prepared bleaching solution was applied for one hour at 37°C. in groups 3 and 4, APF gel was applied either 2 or 4 minutes. SEM analysis of the bleached enamel showed decalcifications in enamel. Fluoride application showed that a thick layer covered the surface but no difference was seen between two application times. in conclusion; as the enamel exposed to bleaching agents showed severe morphologic surface alterations, fluoride application on the bleached enamel could help to protect the enamel.

Özet

Bu çalışmanın amacı diş ağartma ajanları hidrojen peroksit, hidroklorik asit ve eterin diş minesi üzerine etkileri ve ağartılmış mineye topikal fluorid uygulanmasının etkinliğinin araştırılmasıdır. Bu amaçla 4 adet yeni çekilmiş 20 yaş dişi kullanılmıştır. Dişler mesiodistal ve bukkolingual olarak kesilerek 4 eşit parçaya ayrılmıştır. Her dişe ait bir parça kontrol grubu olarak ayrılmıştır. Diğer 3 parçanın mine yüzeyleri dışındaki tüm yüzeyleri aside dayanıklı cila ile örtülmüş ve dişlere 37°C'ta l saat boyunca ağartma ajanları uygulanmıştır. 3. grupta ağartma sonrası 2 dakika APF jel; 4. grupta ise 2 dakika arayla 2 kere APF jel uygulaması yapılmıştır. SEM analizleri, ağartma uygulanan dişlerde mine dekalsifikasyonu göstermiştir. F uygulaması yüzeyde kalın bir tabaka oluşturmuş; ancak uygulama süresinin arttırılması ile fark bulunamamıştır. Sonuç olarak ağartma uygulanan mine yüzeyi şiddetli morfolojik değişimler gösterdiğinden, ağartma sonrası topikal fluorid uygulamalarının yararlı olacağı düşünülmüştür.
