Abrasive Wear of Four Direct Restorative Materials by Standard and Whitening Dentifrices
Abstract
Tooth brushing with dentifrice is the most commonly practiced oral hygiene procedure in developed countries. Abrasives, such as calcium carbonate and hydrated silica, are incorporated into dentifrices to remove food debris and superficial stains. Insufficient abrasiveness promotes the formation of pellicle and increased bacterial adhesion. Whitening toothpastes generally contain harsher abrasives and remove extrinsic stain more effectively than standard toothpastes. However, increased abrasiveness may damage enamel and dentin, as well as restorative materials used for cervical lesions. Moreover, restorative materials may vary in abrasion resistance. New materials must be evaluated to determine their resistance to dentifrice-induced abrasion.
