The purpose of the present study was to verify the effect of exogenous app li cation of Prostaglandi n E, (PGE I) in small dosage on Orthodontic tooth movement in routine orthodontic patients. Fifteen patients were se lected after explaining the experimenta l procedure and obtai ning the wr itten consent. All these patients requi red extract ion of first premolars for the correction of malocclu...

BACKGROUND Gingival Crevicular Fluid (GCF) changes occur during orthodontic tooth movement and this could serve as a potential indicator to the response to active treatment. AIM The objective of the study is to assess the changes in the GCF volume and the levels of Alkaline Phosphatase (ALP) during early phase of tooth movement. METHODS 20 patients requiring all first premolar extractions w...

When maximal anchorage is required during orthodontic treatment, additional aids are often needed to support the anchoring teeth. While intra-oral aids may be limited in their anchorage potential, extra-oral anchoring aids are often rejected by the patients. Endosseous implants may therefore be a valuable alternative for stable intra-oral anchorage. However, the possibility of using conventiona...

Introduction: During sliding mechanics, frictional resistance is an important counterforce to orthodontic tooth movement; which must be controlled to allow application of light continuous forces. objective: To investigate static and kinetic frictional resistance between three orthodontic brackets: ceramic, self-ligating, and stainless steel, and three 0.019×0.025” archwires: stainless steel, ni...

Orthodontic treatment has been shown to induce inflammation, followed by bone remodelling in the periodontium. These processes trigger the secretion of various proteins and enzymes into the saliva. This study aims to identify salivary proteins that change in expression during orthodontic tooth movement. These differentially expressed proteins can potentially serve as protein biomarkers for the ...

The aim of the study was to examine, in vitro, the effect of a vertical force on the debond force and deformation of two multi-stranded wires bonded to the lingual enamel of lower incisor teeth. Two different stainless steel wires were used, 0.016 × 0.022 inch (Bond-A-Braid® Reliance Orthodontic Products) and a three-stranded 0.0175 inch wire (Ortho Technology). An in vitro model was used to si...
