INTRODUCTION Ninety five percent of orthodontic patients routinely report pain, due to alterations in the periodontal ligament and surrounding soft tissues, with intensity and prevalence varying according to age. OBJECTIVE This study aimed to assess toothache and buccal mucosal pain in adults and children during two initial phases of the orthodontic treatment. METHODS The intensity of tooth...

Pain is a common patient complaint during the orthodontic movement of teeth, especially immediately following archwire placement. Vibration has been used to accelerate the orthodontic movement of teeth and some observations by clinicians have indicated that vibration appeared to reduce the pain of orthodontic treatment. The purpose of this parallel group, randomized clinical trial was to invest...

Background- Arch expansion is one of the non- extraction methods gaining space. This study aims to assess and compare arch achieved during initial leveling alignment with three different bracket-archwire combinations.
 Material Methods- was a retrospective done in university setup. From available patient information archives, records 30 subjects based on their advocated bracket system were...

quired several archwire bends to compensate for the lingual morphology of the teeth.1 Not only did this complicate the clinical procedure, but it led to archwire breakage in the bend areas and created impediments to sliding mechanics, potentially interfering with canine retraction. A sliding jig could not be used, and it was difficult to adjust angulations for the correction of root positions. ...

objectives: the aim of this study was to evaluate the effect of four commercially available mouthrinses on the color stability of one type of glass ionomer, giomer and compomer. method: 60 disc-shaped specimens, 180 in total (7*2mm), fabricated from each of the following materials: a resin modified glass ionomer fuji ii lc (gc international corp), a giomer beautifil ii (shofu inc) and a compome...

This study aims at revising the biomechanical principles of the segmented archwire technique as well as describing the clinical conditions in which the rational use of scientific biomechanics is essential to optimize orthodontic treatment and reduce the side effects produced by the straight wire technique.

JCO/APRIL 2010 © 2010 JCO, Inc. C techniques for activating a closing loop are problematic. Cinching the distal end of the archwire can be time-consuming and inaccurate. Tying back an omega loop between the premolars or between the second premolar and first molar is difficult when the interbracket space is narrow. Lacing back the archwire to a hook is possible, but a crimpable hook can come loo...
