Instant tooth whitening from a silica toothpaste containing blue covarine

Evaluation of a new silica whitening toothpaste containing blue covarine on the colour of anterior restoration materials in vitro

“…Four of the treatments show a small, directional decrease in Db*, as the new toothpaste shifts it in the direction of appearing whiter, as it does with tooth enamel. 4,5 For protocol B, Db* and DE after soaking are summarised in Table 3 and Fig. 2, respectively.…”

“…The new toothpaste is making these materials appear temporarily whiter, as it does with tooth enamel. 4,5 While this degree of change in b* still appears whiter rather than bluer, and has resulted from extreme conditions, further decreases in b* would be undesirable if they could not be reversed. The effect of light brushing for 2 min with a 33% (w/w) slurry of a non-whitening silica toothpaste on Db* and DE of the restorations is shown in Table 4 and Fig.…”

“…On brushing with this toothpaste, blue covarine is deposited onto the tooth surface, where it is able to change the optical effects of the tooth surface, and enhances the measurement and perception of tooth whiteness. 4,5 This toothpaste is intended to produce an instant, temporary tooth-whitening effect that can be reapplied as frequently as desired, as it contains no harsh chemicals, but is not intended to produce any permanent changes to colour of the teeth.…”

In vitro cleaning, abrasion and fluoride efficacy of a new silica based whitening toothpaste containing blue covarine

“…8,9 Although the new toothpaste uses novel technology to provide a completely new route to making teeth appear whiter, it must still be able to deliver the performance that consumers would expect of a whitening toothpaste. The aims of the current in vitro studies are to investigate the stain removal, enamel/dentine wear and fluoride efficacy of this new silica based blue covarine whitening toothpaste.…”

Does a toothpaste containing blue covarine have any effect on bleached teeth? An in vitro, randomized and blinded study

“…18 Clinical and laboratorial studies have shown toothpastes containing Blue Covarine produce immediate bleaching effects and have been suggested as a new approach for tooth whitening. 17,18,20 However the effect of this toothpaste on previously bleached teeth has yet to be studied. Thus, this study evaluated the effect of a toothpaste containing Blue Covarine in teeth previously bleached by at-home and in-office techniques.…”
