Application of a Newly Developed Temporary Tooth-Surface Coating Material on Permanent Anterior Teeth with Enamel Discoloration (In Vitro/ Vivo Study)

Abstract

esthetic problems due to discolored crowns are common in pediatric clinical practice. A number of metabolic diseases such as alkaptonuria, and congenital hyperbilirubinaemia can contribute to varying degree of tooth discoloration. Enamel hypoplasia, amelogenesis imperfecta, tetracycline staining and dental fluorosis can appear clinically as severe tooth discoloration and known as environmental and genetic factors that interfere with tooth formation. (Watts and Addy,111 2001)

Such crown discoloration can be treated in adulthood with different crown restoration approaches, such as resin, laminate veneers, crown facing and bleaching treatments. (Ardu et al.,9 2007)

Yet many teeth whitening agents are marketed with the claim that they minimize damage to teeth caused by whitening treatment. However, some studies found that teeth whitening produces dentin hypersensitivity and microcrack formation on tooth surfaces. (Amengual and Forner,6 2009)
