A 180-day clinical investigation of the tooth whitening efficacy of a bleaching gel with added amorphous calcium phosphate.

Abstract

This study demonstrated that the ACP product offers 10% better long-term (6-months) whitening efficacy than the traditional bleaching gel tested. The long-term safety of the product has also been demonstrated, as there were no adverse gingival or other effects seen at either day +90 or day +180.
