objective: adequate knowledge about restorative materials particularly flowable composite resins with favorable physical properties like optimal microhardness and resistance to environmental factors is a big concern for many dentists. flowable composites have several applications for fissure sealant therapy and preventive resin restorations (prr) which are common treatments in pediatric dentist...

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...

Fluoride is now accessible in a variety of forms, including water, toothpaste, mouth rinses, and professional fluoride therapy at dental clinics. A body of data supports the use of systemic and topical fluoride from various sources to prevent dental caries. Fluoride ions are absorbed by the enamel prior to tooth eruption and produce fluorohydroxyapatite, which is more resistant to acid attack t...

Topical fluoride therapy (TFT) in the form of toothpastes, mouthrinses, varnishes and gels are effective caries preventive measures. Different fluoride compounds, different vehicles, and vastly different concentrations have been used with different frequencies and durations of application. These variables can influence the clinical outcome with respect to caries prevention and management. The e...

objectives: fluoride therapy is important for control and prevention of dental caries. laser irradiation can increase fluoride uptake especially when combined with topical fluoride application. the objective of this study was to compare the effects of co 2 and diode lasers on enamel fluoride uptake in primary teeth. materials and methods: forty human primary molars were randomly assigned to fou...

A review of evidence-based literature indicates incomplete evidence for the efficacy of most measures currently used for caries prevention, with the exception of fluoride varnishes and the use of fluoride-based interventions for patients with hyposalivation. Not all fluoride agents and treatments are equal. Different fluoride compounds, different vehicles, and vastly different concentrations ha...

Two cases are presented which exhibit classical dental fluorosis in the permanent dentition which is most logically explained by the excessive intake of fluoride. The cases emphasize the narrow therapeutic range of systemic fluorides in children and the need for analyzing samples of local drinking water before caries-preventive fluoride therapy can be initiated. The potential for induction of f...

The in vitro fluoride uptake by dental enamel from two conventional acidulated phosphate fluoride gels was compared to a thixotropic acidulated phosphate fluoride gel. The fluoride concentration and enamel biopsy depths were determined using an acid-etch biopsy method based on calcium determinations. A significant fluoride uptake by dental enamel from a thixotropic topical fluoride agent follow...
