The hydrolysis of dentin and cementum glycosaminoglycans following fluoride immersion.
The roots of human premolar teeth were analyzed biochemically for total glycosaminoglycan after fluoride treatment and enzymatic digestion. Base levels of dentin and cement~Jm fluoride (780 +_ 105 ppm) and controls showed a statistically significant difference from the fluoride-treated teeth (1250 +__ 120, 1675 +_ 105, 2150 +_ 145 ppm) for the 1-, 8-, and 24-hour periods respectivel.v. The amou...
متن کاملMeasurement of Fluoride Concentration in Semnan Drinking Water Distribution
Background: The existence of fluoride ion in potable water has distinctive effects on human health. Fluoride is attracted by positively charged calcium in teeth and bones due to its strong electro-negativity which results in dental, skeletal, and non-skeletal forms of xuorosis and associated health complaints in children as well as adults. Methods: Water samples from groundwater used for dri...
متن کاملEvaluation of Topical Pre-Fluoride Therapy Effects on Marginal Microleakage of Composite Restorations in Deciduous Teeth: An In Vitro Study
Background and Aim: Since fluoride therapy is usually the first step of treatment in pediatric dentistry and it may interfere with other treatments, such as composite fill-ing, this study aimed to evaluate the possible effects of topical pre-fluoride therapy on marginal microleakage of composite restorations in deciduous teeth. Materials and Methods: In this in-vitro study, 30 deciduous canine...
متن کاملFluoride uptake in vivo deciduous enamel of children from neutral Fluoride and APF mouthrinses.
Abstract. 173 exfoliated teeth were collected from three groups of children, age 9-10 years, who for three school years used daily one of three mouthrinses consisting of (a) 200 ppm F, 0.1 M phosphate at pH 4.0, (b) 200 ppm F at pH 7.0, or (c) a placebo rinse. The average F concentration at 5 μm in 58 placebo treated teeth was 595 ppm. After approximately 190 rinses, the average F concentration...
متن کاملFracture resistance of cementum-extended composite fillings in severely damaged deciduous incisors: An in vitro study
OBJECTIVE The aim of this study was to comparatively assess the fracture resistance of the cementum-extended and conventional composite fillings with or without intracanal composite posts in severely damaged deciduous incisors. MATERIALS AND METHODS This in vitro study was performed on 60 extracted deciduous maxillary incisors that were randomly divided into four groups: Group 1: Composite fi...
