Analysis of biological pathways, associated with orthodontic force, using multiplex arrays
Objective - investigate tissue changes induced by orthodontic forces at tension and compression sites. Methods - Gingival Crevicular Fluid (GCF), was collected from maxillary canines and second molars from volunteers (n=21), before appliance placement and tooth extraction (B); 3 months into …

Automation of Orthodontic Wire Tester for Performing Three Point Bending Tests
… <p>Understanding the biomechanical factors in orthodontics is important in order to improve the overall effectiveness of actual clinical treatment. An accurate method to study the threedimensional (3D) force systems and the resulting movements of teeth during orthodontic treatment is needed …

Influência clínica e tecidual do diazepam no periodonto de sustentação durante o movimento ortodôntico
… hydrolysis, on the tissue reactions related to orthodontic tooth movement. There is evidence suggesting that cAMP plays an important role as intracellular mediator of bone remodeling induced by mechanical stress. The sample consisted of thirty-six guinea pigs (Cavia porcellus), 9 weeks of age, …

Mandibular Resting Posture : An Electromyographic Evaluation
… as a proximal separator which is analgous to an orthodontic force, as it causes the teeth to move in opposite directions.</p> <p>Following a random selection of observations of each treatment, these were measured with a map measurer by two observers to obtain objective, quantitative values.</p> …

RANKL and Osteoprotegerin Levels in Response to Orthodontic Forces
<p>Orthodontic tooth movement is mediated by interactions between PDL cells and those of the alveolus. One protein—the receptor activator nuclear factor kappa B ligand (RANKL)—is critical for osteoclastogenesis, and osteoprotegerin (OPG) is a decoy ligand that competitively inhibits RANKL. A higher …

Modulation of RANKL and Osteoprotegerin in Adolescents Using Orthodontic Forces
<p>Orthodontic tooth movement is mediated by interactions between PDL cells and those of the alveolus. One protein--the receptor activator nuclear factor kappa B ligand (RANKL)--is critical for osteoclastogenesis, and osteoprotegerin (OPG) is a decoy ligand that competitively inhibits RANKL. A …
