Galvanic corrosion between orthodontic wires and brackets in fluoride mouthwashes.
The aim of this investigation was to determine the influence of fluoride in certain mouthwashes on the risk of corrosion through galvanic coupling of orthodontic wires and brackets. Two titanium alloy wires, nickel-titanium (NiTi) and copper-nickel-titanium (CuNiTi), and the three most commonly used brackets, titanium (Ti), iron-chromium-nickel (FeCrNi) and cobalt-chromium (CoCr), were tested i...
متن کاملThree-dimensional deformation of orthodontic brackets
Braces are used by orthodontists to correct the misalignment of teeth in the mouth. Archwire rotation is a particular procedure used to correct tooth inclination. Wire rotation can result in deformation to the orthodontic brackets, and an orthodontic torque simulator has been designed to examine this wire-bracket interaction. An optical technique has been employed to measure the deformation due...
متن کاملWomen in science — passion and prejudice
(Chris Comer, of the Texas Education Agency) who are hounded out of their jobs because of their support of evolution in school curricula, and have initial nods toward sanctioning the Institute for Creation Research (now located in Dallas) by the Texas Higher Education Coordinating Board, the same state agency that certifies the school I work at, the University of Texas at Austin. That said, I r...
متن کاملShear bond strength comparison between two orthodontic adhesives and self-ligating and conventional brackets.
OBJECTIVE To evaluate and compare the shear bond strengths of two adhesives using two types of brackets: a conventional and a self-ligating bracket system. MATERIALS AND METHODS Sixty extracted human premolars were collected. The premolars were randomly divided into three groups of 20 teeth. All three groups were direct bonded. Groups 1 and 2 used light-cured adhesive and primer (Transbond XT...
متن کاملComparison of shear bond strength and adhesive remnant index between precoated and conventionally bonded orthodontic brackets
BACKGROUND The purpose of this study was to compare the shear bond strength and adhesive remnant index (ARI) at the enamel-bonding interface of precoated and conventionally bonded brackets, utilizing standardized procedures. METHODS The test sample consisted of 90 recently extracted bovine permanent mandibular incisors. The teeth were bonded using the same protocol and were tested in three di...
