phosphoric acid (orthophosphoric acid)

07/01/1996 - "This study was conducted to investigate the influence of phosphoric acid (H3PO44) demineralization of dentin during smear layer removal prior to dentin bonding. "
08/01/1993 - "The purpose of this study was to examine the effect that phosphoric acid etchant, used to remove the smear layer, may have on dentin demineralization inhibition. "
03/01/2015 - "Phosphoric acid has been suggested as an irrigant due to its effectiveness in removing the smear layer. "
07/01/2014 - "Application of 35% orthophosphoric acid gel for 15 seconds on retrocavities prepared with ultrasonic retro-tips is the most effective means for removal of smear layer."
11/01/2013 - "Liquid phosphoric acid applied with an endodontic needle yielded better canal wall smear layer removal and higher bond strength values when an etch-and-rinse system was used."

03/01/2015 - "The teeth were distributed into 12 groups (n=10) according to the substrate; etched or not with 37% phosphoric acid; and cement type of enamel-U100, enamel-phosphoric acid-U100, enamel-U200, enamel-phosphoric acid-U200, enamel-ARC, enamel-phosphoric acid-ARC, dentin-U100, dentin-phosphoric acid-U100, dentin-U200, dentin-phosphoric acid-U200, dentin-ARC, and dentin-phosphoric acid-ARC. "
11/01/2010 - "For ARC, the dentin surface was treated with 32% phosphoric acid. "
03/01/2015 - "U200 self-adhesive cement had similar bond strength to the ARC in enamel, but the combination with phosphoric acid had the best bond strength. "
07/01/2012 - "EDTA was applied for 45 seconds on smear-covered dentin in the U100/EDTA group, and it replaced phosphoric acid conditioning in the ARC/EDTA group for 60 seconds. "
12/01/2009 - "For RelyX ARC (ARC, 3M ESPE), dentin surfaces were etched with 32% phosphoric acid. "

03/01/1989 - "Sealing white spot lesions following etching with a 37% phosphoric acid may be beneficial in inhibiting lesion progression."
07/27/2002 - "QLF images were taken of 20 human molar teeth that had been previously subjected to a demineralizing solution (phosphoric acid 37%) to create artificial white spot lesions on their buccal surfaces. "
09/01/1997 - "Etching patterns by 20 percent phosphoric acid on caries-like lesions of enamel (white spot) untreated and treated with 0.4 APF were studied at 30, 60, 120 seconds of etch-times using the Scanning Electron Microscope (SEM). "
04/01/1995 - "Ultrastructural changes in surface characteristics of enamel white-spot lesions were compared with changes in the adjacent clinically sound enamel after they were etched with 30% phosphoric acid. "
03/01/1989 - "The resistance of white spot lesions to acid demineralization when etched with phosphoric acid and sealed with a resin material was studied. "

03/01/2009 - "Etching with phosphoric acid improved the enamel marginal sealing of the 3 self-etch adhesives when specimens were subjected to thermal fatigue."
07/01/2015 - "The purpose of this study was to use shear bond strength (SBS) and shear fatigue limit (SFL) testing to determine the effect of phosphoric acid pre-etching of enamel and dentin prior to application of self-etch adhesives for bonding resin composite to these substrates. "
12/01/2015 - "The shear bond strength (SBS) and shear fatigue strength (FS) of the enamel and dentin were obtained with and without phosphoric acid pre-etching prior to application of the adhesives. "
07/01/2015 - "Effect of Phosphoric Acid Pre-etching on Fatigue Limits of Self-etching Adhesives."
12/01/1996 - "The goal of this project was to evaluate the effect of the following variables on shear dentin-bonding test results: mode of testing (cyclic fatigue versus static loading), surface treatments (32% phosphoric acid, 10% phosphoric acid, and no treatment [unetched]), and type of shear test (traditional planar versus push-out). "

09/01/2011 - "45S5 bioglass mixed with 50% phosphoric acid has been suggested to treat dentine hypersensitivity and incipient enamel caries. "
04/01/2007 - "DP-bioglass mixed with 30% phosphoric acid has been suggested to treat dentin hypersensitivity because the material is able to produce homogeneous occlusion of exposed dentinal tubules and is able to provide a sealing depth of up to 60 microm. "
02/01/2011 - "In this study, 45S5 bioglass was mixed with phosphoric acid and irradiated with CO(2) laser and examined as a possible aid in the treatment of dentin hypersensitivity. "
