“…In addition, the contact and possible diffusion of free radicals produced by bleaching agents can selectively extract the alkaline ions of ceramic network, causing damage [11,24]. The polymer network may also be affected by the erosion on the surface of the matrix and is dependent on resin matrix components and filler size [14,25].…”

“…However, 10 to 15% carbamide peroxide bleaching agents are the most widely used as at home products. The literature contains several reports of their safety and effectiveness of hydrogen peroxide releasing agents like carbamide peroxide or sodium perborate [11]. Unfortunately the bleaching procedure can be responsible for causing alterations of enamel surface, or dental materials, and tooth sensitivity [12].…”

“…This is described as the main cause behind the adverse effects due to structural changes of the restorative materials, and this might lead to material failure. 15,16 The difference in the bleaching materials and the techniques exerts different impacts on different restorative materials. [17][18][19] Although traditional dental ceramics are considered to be the most inert dental restorative material among others, their surfaces were reported to manifest surface deterioration on contact with some acidulated materials, such as fluoride gels and other solutions.…”

Aim: This study evaluated the effect of light-emitting diode (LED) illumination bleaching technique on the surface nanohardness of various computer-aided design and computer-aided manufacturing (CAD/CAM) ceramic materials. Materials and methods:Twenty disk-shaped samples (width, length, and thickness = 10, 15, and 2 mm) were prepared from each of the ceramic materials for CAD/CAM, including Lava™ Ultimate (L V ), Vita Enamic ® (E n ) IPS e.max ® CAD (M e ), inCoris ® TZI (I C ), and Prettau ® zirconia (P r ). The samples from each type of ceramic were randomly divided into two groups based on the different bleaching techniques to be used on them, using 35% hydrogen peroxide with and without LED illumination. The ceramic disk samples were bleached according to the manufacturer's instruction. Surface hardness test was performed before and after bleaching using nanohardness tester with a Berkovich diamond indenter. Results Conclusion:Bleaching resulted in a diminution of the surface hardness of dental ceramic for CAD/CAM. Using 35% hydrogen peroxide bleaching agent with LED illumination exhibited more reduction in surface hardness of dental ceramic than what was observed without LED illumination.Clinical significance: Clinicians should consider protection of the existing restoration while bleaching.

Available online ---KEYWORDS bleaching; carbamide peroxide; hydrogen peroxide; restorative material Abstract In recent years, there has been an increased demand for improvement in the appearance of natural teeth. The conservative technique of tooth bleaching has gained attention and acceptance from both patients and clinicians. Despite increased popularity, there is controversy surrounding the adverse effects of bleaching on dental restorative materials. This article reviews the effects of bleaching agents on major categories of dental restorative materials and provides evidence-based recommendations to the clinicians and researchers. Current literature reveal that bleaching might have a detrimental effect on restorative materials. However, because of the variability in experimental design, there is a lack of consensus concerning the bleaching effects on restorative materials. A standardized and reproducible guideline for assessment of bleaching effects on restorative materials needs to be established and verified by future studies.
