Bioactive materials have shown positive results in reducing the deleterious effects of tooth whitening. However, their on whitening efficacy is still uncertain. Therefore, aim this study was to evaluate F- 18 bioactive glass incorporation into a bleaching gel color and microhardness enamel after Thirty bovine enamel-stained specimens were randomly divided three groups (n=10) according protocol:...

background: bleaching the discoloured teeth may affect the tooth/composite interface. the aim of this in vitro experimental study was to evaluate the effect of vital tooth bleaching on microleakage of existent class v composite resin restorations bonded with three dental bonding agents.     methods: class v cavities were prepared on buccal surfaces of 72 intact, extracted human anterior teeth w...

Thirty-six human teeth were examined to histologically determine if the Modified Mclnnes Bleaching Technique had any adverse effects on the pulp. Under the conditions of this study, there were no significant pulpal reactions to the bleaching technique even when a substantial amount of the enamel was removed from the facial surface of the crowns. J. Craig Baumgartner 4 The Modified McInnes Bleac...

With regard to the best moment for carrying out or recommending dental bleaching to orthodontic patients, some explanations and orientations are given in order to answers the following questions: 1) Why orthodontic treatment completion is considered the best opportunity for carrying out the procedure? 2) Why dental bleaching should not be performed immediately before orthodontic treatment? 3) I...
