Penetration of 38% hydrogen peroxide into the pulp chamber in bovine and human teeth submitted to office bleach technique
(Elsevier B.V., 2007-09-01)
This study evaluated the pulp chamber penetration of peroxide bleaching agent in human and bovine teeth after office bleach technique. All the teeth were sectioned 3 mm apical of the cement-enamel junction and were divided ...

Study of DNA damage induced by dental bleaching agents in vitro
(2006-06-01)
Dental bleaching is a simple and conservative procedure for aesthetic restoration of vital and non-vital discolored teeth. Nevertheless, a number of studies have demonstrated the risk of tissue damage from the contact of ...
Tuning the acidic properties of aluminas via sol-gel synthesis: New findings on the active site of alumina-catalyzed epoxidation with hydrogen peroxide
(Elsevier B.V., 2006-11-15)
This study answers several pending questions about alumina-catalyzed epoxidation with aqueous 70 wt% H2O2. To evaluate the effect of the water-to-aluminum tri-sec-butoxide molar ratio, this was systematically changed from ...

(Lippincott Williams & Wilkins, 2005-08-01)
Objective: To evaluate oro-cecal transit time in children with chronic constipation.Methods: 34 patients with chronic functional constipation age 3 to 13 years and 15 controls without constipation. Oro-cecal transit time ...
A surface modification for hydrogen storage intermetallic particles by sol-gel method
(2001-12-01)
A new process for the surface modification of hydrogen storage intermetallic particles used as anode material in secondary batteries is proposed in this article. The copper oxide particles coverage obtained by the sol-gel ...
A simplified spectrophotometric method for routine analysis of saccharin in commercial noncaloric sweeteners
(2004-12-29)
A simple, rapid, and sensitive spectrophotometric method for routine analysis of saccharin in commercial noncaloric sweeteners is proposed. This method is based on the reaction of saccharin with tetrachloro-p-benzoquinone ...
