Calibration of equipment for analysis of drinking water fluoride: a comparison study.

Current American Dental Association evidence-based recommendations for prescription of dietary fluoride supplements are based in part on the fluoride concentration of a pediatric patient's drinking water. With these recommendations in mind, this study compared the relative accuracy of fluoride concentration analysis when a common apparatus is calibrated with different combinations of standard values. Fluoride solutions in increments of 0.

Hand-held water fluoride analysis: An accessible caries prevention tool for dental professionals.

This study sought to compare the relative accuracy of a commercially available hand-held water fluoride analysis unit with a standard laboratory bench-top fluoride-specific electrode/millivoltmeter apparatus, with the goal of identifying possible practical applications of the hand-held unit for preventive dentistry. The units analyzed identical gravimetrically prepared fluoride solutions ranging from 0.1 to 4.

Weekly monitoring of the water fluoride content in a fluoridated metropolitan city--results after 1 year.

It continues to be the goal of the United States Department of Health and Human Services to fluoridate community water supplies to prevent dental caries. In Houston, Texas, where community water is assumed to contain in the range of 0.7-1.

Fluoride content of bottled water and its implications for the general dentist.

This study sought to measure the fluoride concentration of various commercial bottled waters and to identify clinical implications in dental patient education and treatment. For this study, 105 different samples of bottled water were collected over a 30-day period (from October 15, 2007 to November 15, 2007), divided into six categories, and analyzed for fluoride concentration by utilizing a fluoride ion-specific electrode. Based on the present study, distilled bottled waters have an average fluoride content of less than 0.

Effects of a stannous fluoride-impregnated dental floss on in vivo salivary fluoride levels.

Purpose: The aim of this in vivo pilot study was to determine the concentration of fluoride retained intra-orally in saliva after flossing with dental floss impregnated with stannous fluoride (SnF(2)).

Methods: Participants flossed their teeth ad libitum with 2 premeasured lengths of fluoridated dental floss. Expectorated saliva samples were collected in vials before flossing (PF), immediately postflossing(IPF), at 30 minutes (30), and 1 hour (60) after flossing for analysis with a fluoride-specific electrode and an Orion millivoltmeter.

Spontaneous recovery from early glomerular inflammation is associated with resistance to anti-GBM glomerulonephritis: tolerance and autoimmune tissue injury.

Different susceptibility to anti-GBM glomerulonephritis (GN) among animal strains has been reported. Using our rat model for T cell-mediated anti-GBM GN, this study initiated an investigation on the mechanism related with GN susceptibility. Anti-GBM GN was induced either through immunization with the nephritogenic T cell epitope pCol(28-40) from Col4alpha3NC1 or through the transfer of specific T cells.

Fluoride knowledge and prescription practices among dentists.

The purpose of this study was to assess dentists' knowledge about fluorides as well as their prescription practices. The study population consists of all general and pediatric dentists in Houston, and the sample consists of 360 general and forty-one pediatric dentists. Data were collected with a self-administered mail questionnaire, which consisted of thirteen open-ended and twenty-nine precoded items.

Tensile bond strengths of five luting agents to two CAD-CAM restorative materials and enamel.

Statement Of Problem: CAD-CAM restorative materials are popular because they have high esthetic value and short fabrication time. Unfortunately these materials are brittle and tend to fracture under heavy occlusal load.

Purpose: The purpose of this in vitro study was to investigate the tensile bond strengths of 5 luting agents to 2 CAD-CAM restorative materials and enamel.
