Hard Tissues

Clinical Relevance In dental bleaching, the micromorphological alterations of hard tissues have been well investigated, but little is known about the optical changes involved. The results of the current study showed that enamel, irrespective of maturation, is subjected to a shift in reflectance towards blue within the color space and enhanced reflection. This effect was demonstrated in different bleaching agent concentrations and protocols.

A literature review on the existing information about bonding of orthodontic brackets on altered enamel surfaces, the influence of such surfaces on adhesion, and the most favorable conditions for achieving better bond strength is presented. Studies on bracket adhesion have identified the conditions that lead to morphological changes in enamel as dental fluorosis and dental bleaching. In this review, each of these conditions that alter the enamel surface and pose a major challenge to clinical orthodontists performing bracket bonding, will be analyzed. The literature provides a range of approaches for overcoming the challenges of bonding on altered enamel surfaces and will be discussed, taking into account, where possible, the type of adhesive selected. Adhesion on enamel that is fluorosed depends on the degree of severity and the bond strength on a bleached enamel surface depends largely on the concentration of the bleaching agent.

Clinical Relevance The efficacy of vital bleaching depends on the two aspects—viz, bleaching agent and the bleaching method. Results from this in vivo study show that 10% carbamide peroxide home-bleaching and 15% hydrogen peroxide in-office bleaching were more effective than a 6% hydrogen peroxide home-bleaching over-the-counter product up to three months after completion of the bleaching treatment.

Clinical Relevance Fluorescence is one of the optical properties of resin composites and dental tissues that is of great interest today. The fluorescence intensity of restorative materials should be as close as possible to that of human enamel and dentin to ensure an acceptable reproduction of these qualities in esthetic restorations.
