Transarterial embolization of direct carotid-cavernous fistulas (CCFs) using detachable balloons is the best initial option for occlusion of the fistula and preservation of the internal carotid artery. However, the long-term safety and efficacy of this treatment is unknown. The authors reviewed the long-term outcome of 87 patients with 88 direct CCFs(More)
PURPOSE To compare the ability of two active ingredients - sodium fluoride (NaF) and stannous fluoride (SnF2 ) - to inhibit hydroxyapatite (HAP) dissolution in buffered acidic media. METHODS Two in vitro studies were conducted. HAP powder, which is representative of tooth mineral, was pretreated with: test solutions of NaF or SnF2 , 10 g solution per 300(More)
Stannous fluoride has been used as a chemotherapeutic agent for years to improve oral health. The benefits of stannous fluoride in controlling caries, plaque, and gingivitis are directly associated with its antimicrobial actions. Recently, a novel dentifrice was developed that combines stannous fluoride with an anticalculus agent, sodium hexa.(More)
The objective of this research was to evaluate the anticaries potential of stabilized stannous fluoride and sodium hexametaphosphate dentifrice using a series of laboratory studies. In a study of fluoride uptake into demineralized enamel, the stannous fluoride/sodium hexametaphosphate dentifrice exhibited fluoride uptake comparable to the clinically proven(More)
OBJECTIVE The purpose of this study was to compare the reactivity of three dentifrice formulations on smear layer-covered root dentin surfaces, and the effects of the formulation treatments on resistance to acid softening and dentinal tubuli disclosure. METHODOLOGY Commercial dentifrices, including Crest Cavity Protection Regular, Colgate Total, and a new(More)
