Use of 37% carbamide peroxide in the walking bleach technique: A case report
(2004-02-01)
Dental bleaching represents an effective, conservative, and relatively low-cost method for improving the appearance of discolored pulpless teeth. Among the bleaching techniques, the walking bleach technique with sodium ...
Effect of calcium hydroxide on pH changes of the external medium after intracoronal bleaching
(2011-05-01)
Aim: This in vitro study evaluated the effect of calcium hydroxide on pH changes of the external medium after intracoronal bleaching. Materials and methods: A total of 50 extracted human premolars were prepared and filled ...
In vitro evaluation of the microhardness of bovine enamel exposed to acid solutions after bleaching
(Sociedade Brasileira de Pesquisa Odontológica (SBPqO), 2011-11-01)
Acid erosion is a superficial loss of enamel caused by chemical processes that do not involve bacteria. Intrinsic and extrinsic factors, such as the presence of acid substances in the oral cavity, may cause a pH reduction, ...
Effect of bleaching on sound enamel and with early artificial caries lesions using confocal laser microscopy
(2012-03-01)
The aim of this study was to evaluate effect of bleaching agents on sound enamel (SE) and enamel with early artificial caries lesions (CL) using confocal laser scanning microscopy (CLSM). Eighty blocks (4 × 5 × 5 mm) of ...
pH-changes during intracoronal bleaching: An in vivo study
(2011-03-01)
Objectives: This study aimed to measure pH changes during 14 days intracoronal bleaching with hydrogen peroxide/sodium perborate and carbamide peroxide/sodium perborate. Materials and methods: Twenty patients presenting ...
Response of human pulps after professionally applied vital tooth bleaching
(Wiley-Blackwell, 2010-07-01)
P>AimTo evaluate in vivo the microscopic pulpal response in sound human premolar teeth subjected to vital tooth bleaching with a 38% hydrogen peroxide (H(2)O(2)) bleaching gel (Opalescence X-tra Boost) catalysed or not by ...
In vitro penetration of bleaching agents into the pulp chamber
(2004-02-01)
Aim: To investigate pulp chamber penetration of bleaching agents in teeth following restorative procedures. Methodology: Bovine lateral incisors were sectioned 3 mm apical to the cemento-enamel junction and the coronal ...
Efficacy and cytotoxicity of a bleaching gel after short application times on dental enamel
(2012-12-06)
Objectives: This study aimed to evaluate and correlate the efficacy and cytotoxicity of a 35 % hydrogen peroxide (HP) bleaching gel after different application times on dental enamel. Materials and methods: Enamel/dentin ...
