BACKGROUND AND OBJECTIVES Low-intensity laser therapy (LILT) has been studied in many fields of dentistry, but to our knowledge, this is the first time that its effects on orthodontic movement velocity in humans are investigated. STUDY DESIGN/PATIENTS AND METHODS Eleven patients were recruited for this 2-month study. One half of the upper arcade was considered control group (CG) and received ...

The aim of this study was to develop a mathematic model to describe the relationship between magnitude of applied force and rate of orthodontic tooth movement. Initially, data were extracted from experimental studies in dogs (beagles), in which controlled, standardized forces were used to move mandibular second premolars distally. Curve-fitting by nonlinear regression analysis provided an equat...

OBJECTIVES To test the hypothesis that mechanical forces combined with low-level laser therapy stimulate the rate of orthodontic tooth movement. STUDY DESIGN This study was a double blind, randomized placebo/control matched pairs clinical trial to test the efficacy of GaAlAs low-level laser therapy (LLLT) on 12 young adult patients who required retraction of maxillary canines into first premo...

PURPOSE To describe a series of patients with lower eyelid epiblepharon associated with lower eyelid retraction. METHODS We retrospectively reviewed the medical records of patients who underwent surgery for lower eyelid retraction, epiblepharon, or thyroid-associated ophthalmopathy (TAO) between October 1999 and March 2007. Patients with both lower eyelid retraction and epiblepharon on preope...

duane’s retraction syndrome (drs) type i is often associated with esotropia (et) and face turn in those with fusion. this study was designed to delineate the quantitative relationship between the angles of eye deviation with that of face turn. ten patients with drs type i with et and face turn toward the deviated eye, who had central fixation, were chosen. esodeviation was measured by alternate...
