a vast majority of the studies addressing the free radicals including hydroxyl radical is a damage compound of biochemical molecules such as dna, proteins and lipids. when free radicals specially hydroxyl radical are not adequately removed from the body, it may damage biological macromolecules, leading to a variety of disease occurs. therefore, the body should be protected by an enzymatic or no...

abstractintroduction: we researched to study the effect of berberis vulgaris supplementation on glycemic indices patients with diabetes type 2 after one session of aerobic exercise in accordance to independent effects of barberry extract and aerobic exercise.methods and material: 32 patient men with type 2 diabetes accidently divided into four groups of barberry extract (10 cc per 200 ml of wat...

In order to compare the antiplaque and antigingivitis activity of three commercially-available triclosan containing dentifrices with that of a placebo dentifrice without triclosan, a double-blind clinical study was conducted on 194 subjects over six months. Following baseline supragingival plaque and gingivitis examinations and a complete oral prophylaxis, subjects were stratified by their whol...

The objective of this research was to evaluate the anticaries effectiveness of a low-dose (500 ppm F, low-NaF) sodium fluoride dentifrice, a high-dose (2,800 ppm F, high-NaF) sodium fluoride dentifrice and an experimental 0.454% stabilized stannous fluoride (1,100 ppm F) with sodium hexametaphosphate (SnF2-HMP) dentifrice, each relative to a standard 1,100 ppm F sodium fluoride positive control...

The aim of this study was to investigate, in vitro, the morphological characteristics of demineralized primary enamel subjected to brushing with a dentifrice with or without fluoride. In order to do so, 32 enamel blocks were divided in 4 different groups containing 8 blocks each. They were separately immersed in artificial saliva for 15 days. The experimental groups were: C - control; E - submi...

This study evaluated the capacity of fluoride acidic dentifrices (pH 4.5) to promote enamel remineralization using a pH cycling model, comparing them with a standard dentifrice (1,100 µgF/g). Enamel blocks had their surface polished and surface hardness determined (SH). Next, they were submitted to subsurface enamel demineralization and to post-demineralization surface hardness analysis. The bl...

The aim of the study was to evaluate salivary fluoride (F) availability after toothbrushing with a high-F dentifrice. Twelve adult volunteers took part in this crossover and blind study. F concentration in saliva was determined after brushing with a high-F dentifrice (5000 µg F/g) or with a conventional F concentration dentifrice (1100 µg F/g) followed by a 15 mL distilled water rinse. Samples ...

Objective: The purpose of this study was to examine the effects of various product combinations involving brush, paste, rinse, and floss on the prevention of plaque regrowth and gingivitis. • Methodology: In this randomized, parallel-group, examiner-blind, eight-week study, 179 subjects with gingivitis had a dental prophylaxis and were randomly assigned to one of six product combinations: 1) Co...

This investigation compared the effects of a fluoride dentifrice and toothpastes formulated with antimicrobial ingredients (stannous fluoride and triclosan/copolymer) on oral micro-organisms, including those found in samples taken from the human oral cavity. Microbiological techniques determined the minimum inhibitory concentrations (MICs) of each dentifrice necessary to inhibit the growth of b...
