nitrates and Tooth Erosion

nitrates has been researched along with Tooth Erosion in 20 studies

Nitrates: Inorganic or organic salts and esters of nitric acid. These compounds contain the NO3- radical.

Tooth Erosion: Progressive loss of the hard substance of a tooth by chemical processes that do not involve bacterial action. (Jablonski, Dictionary of Dentistry, 1992, p296)

Dentinal Hypersensitivity

"The primary analysis will be to compare the dentinal hypersensitivity between the 3 groups.~Air test: A 1 second blast of air from the air-water syringe was applied to the tooth.~Water test: Three drops of ice water were be placed on the tooth.~Schiff Score~Investigator observed participant reaction to test and scored on following scale:~0-Tooth/Subject does not respond to stimulus.~Tooth/Subject responds to stimulus, but does not request discontinuation of stimulus.~Tooth/Subject responds to stimulus and requests discontinuation or moves from stimulus.~Tooth/Subject responds to stimulus, considers stimulus to be painful, and requests discontinuation of the stimulus~VAS (visual analog scale):~The participant reported sensitivity on a scale of 0-10. 0 being no pain and 10 being worst pain imaginable."

Timeframe: 8 weeks after baseline

Adjusted Mean Percent NER of Enamel Specimens Exposed to a Treatment Regimen of Placebo Dentifrice + Test MR Relative to: 1) Test Dentifrice +Test MR 2) Test Dentifrice + Sterile Water Rinse 3) Reference Dentifrice +Sterile Water Rinse

Enamel specimens were exposed to dietary erosive challenge and set of five indentations within each specimen was measured. Decrease in the indentation length compared to the baseline indicates hardening of enamel surface. Enamel specimens were exposed to second erosion challenge to determine NER which compared the indentations values of enamel specimens at baseline (B), first erosive (E1) and second erosive challenge (E2). Percent NER was calculated by formula: [(E1-E2)/ (E1-B)]*100. Smaller the negative NER, better is treatment regimen in imparting resistance to enamel. (NCT01128972)
Timeframe: Baseline, 4 hours post treatment in each treatment period

Adjusted Mean Percent SMH Recovery of Enamel Specimens Exposed to Test Dentifrice +Sterile Water Rinse and Reference Dentifrice +Sterile Water Rinse

SMH test was used to assess mineralization status of enamel specimens using a Wilson 2100 Hardness tester. SMH was determined by measuring the length of the indentations of enamel specimens. An increase in the indentation length compared to the baseline indicates softening while decrease in the indentation length represents rehardening of enamel surface. Percent SMH recovery was calculated from indentation values of enamel specimens at baseline (B), after in-situ hardening (R) and after first erosive challenge (E1) using formula: [(E1-R)/ (E1-B)]*100. (NCT01128972)
Timeframe: Baseline, 4 hours post treatment in each treatment period
