A new approach for professional dental bleaching using a polymeric catalyst primer.

Journal of Esthetic and Restorative Dentistry, 2022
OBJECTIVE Evaluate the influence of a polymeric catalyst primer (PCP) on esthetic efficacy (EE), degradation kinetics of hydrogen peroxide (H2 O2 ), and trans-amelodentinal cytotoxicity (TC) of bleaching gels. MATERIALS AND METHODS The following groups

Vital Tooth Bleaching in Dental Practice: 2. Novel Bleaching Systems

Dental Update, 2006
This paper describes some of the novel commercial approaches to tooth bleaching. Known as ‘direct-to-consumer’ products there are two main systems available, one employing coated, cellulose strips and the other a paint-on gel. A further development is the production of dentifrices that contain active hydrogen peroxide, made possible by the use of dual

Effect of topical application of nanoencapsulated eugenol on dental sensitivity reduction after in-office dental bleaching: a randomized, triple-blind clinical trial.

Journal of Esthetic and Restorative Dentistry, 2021
PURPOSE This randomized, split-mouth, triple-blind clinical study evaluated the effect of application of nanoencapsulated eugenol (NE) on the absolute risk and intensity of tooth sensitivity (TS) resulting from in-office bleaching.

Effectiveness of Remineralization Agents on the Prevention of Dental Bleaching Induced Sensitivity: A Randomized Clinical Trial.

International Journal of Dental Hygiene, 2021
OBJECTIVES This study aims to compare the use of different remineralization agents before in-office bleaching for decreasing bleaching induced sensitivity. METHODS A total of 64 volunteers were randomly divided into four groups.

Polymeric biomaterials maintained the esthetic efficacy and reduced the cytotoxicity of in-office dental bleaching.

Journal of Esthetic and Restorative Dentistry, 2021
Evaluate the kinetics of hydrogen peroxide (H2 O2 ) degradation, esthetic efficacy and cytotoxicity of a bleaching gel with 35%H2 O2 applied on enamel previously covered or not with polymeric nanofibrillar scaffold (SNan), polymeric primer catalyst (PPol)

DNA-Damaging Effects of Dental Bleaching Agents

Bulletin of Experimental Biology and Medicine, 2012
We studied DNA-damaging effects of dental bleaching systems containing hydrogen peroxide and/or carbamide peroxide by the "comet assay" (alkaline version). Dental bleaching systems in a hydrogen peroxide concentration range from 0.03 to 30 mM produced a genotoxic effect on isolated HeLa cells in vitro comparable with the effects of pharmacopoeial ...

In-Office Dental Bleaching Using 37% Carbamide Peroxide Versus 35% Hydrogen Peroxide: A Randomized, Double-Blind Clinical Trial.

Journal of Esthetic and Restorative Dentistry
OBJECTIVE Compare the tooth sensitivity (TS) and bleaching efficacy (BE) of in-office dental bleaching performed with 35% hydrogen peroxide (HP) or 37% carbamide peroxide (CP). MATERIALS AND METHODS Sixty-six participants were randomly divided into two

Dental Bleaching: ‘Now I can Smile for my Selfies’ – Paediatric Patients’ Perspectives

Primary Dental Journal, 2021
Children presenting with discoloured teeth commonly suffer from low self-esteem. This paper reports the findings from a questionnaire evaluating changes brought about by dental bleaching and the psychosocial effects of bleaching on 22 patients.

Histochemical analysis of dental hard tissues following bleaching

Journal of Endodontics, 1996
The effect of commonly used bleaching materials on the dental hard tissues was tested in extracted human premolars. In each tooth, the apical two-thirds of the root was removed, and the remaining tooth stump was cut longitudinally into two equal segments. The segments were cleaned, dried, and divided into six experimental groups. Each group was treated
