objectives: the purpose of this study was to evaluate whether intra-canal application of controlled direct electric current (dec) could accelerate the amount of orthodontic tooth movement (otm) in young adult mixed breed dogs. methods: fourth premolars of both jaws of five young adult mixed breed dogs were divided into two groups of control and experimental groups. orthodontic force was applied...

INTRODUCTION The aim of this study was to investigate the variation in the amount of the orthodontically induced tooth movement in humans and potential associations between the amount of tooth movement with age and location in the mandible or maxilla. SUBJECTS AND METHODS This study included 11 participants (7 females, 4 males) with an age range of 11.3-28.6 years. In a standardized experimen...

background. this clinical trial evaluated the effect of simvastatin on space re-opening after orthodontic space closure and its effect on the gingival index (gi) and clinical attachment loss (cal). methods. 16 females, 25‒40 years old, with spaces between anterior mandibular teeth due to chronic periodontitis were participated in this study. the patients were randomly divided into control and e...

INTRODUCTION Recently, several reviews have been published on the effects of medications on bone physiology and the clinical side effects in orthodontics. However, the effects of medications on the rate of orthodontic tooth movement have not been evaluated. METHODS A systematic literature review on the effects of medications and dietary supplements on the rate of experimental tooth movement w...

The purpose of this article is to simulate long-term movement of maxillary teeth connected with an archwire and to clarify the difference between the initial tooth movement and the long-term orthodontic movement. Initial tooth movement was calculated based on the elastic deformation of the periodontal ligament. Orthodontic tooth movement was simulated based on the bone remodeling law of the alv...

objectives : bone remodeling occurs during orthodontic treatment; this process enables tooth movement. many factors can affect bone remodeling at the cellular level, such as nutritional supplements that can affect tooth movement. the present study was designed to evaluate the effect of dietary vitamin c on orthodontic tooth movement in rats.  materials and methods: this study was carried out on...

Nowadays, there is an increased tendency for researches to focus on accelerating methods for tooth movement due to the huge demand for adults for a shorter orthodontic treatment time. Unfortunately, long orthodontic treatment time poses several disadvantages like higher predisposition to caries, gingival recession, and root resorption. This increases the demand to find the best method to increa...

INTRODUCTION The purpose of this study was to investigate the variations of orthodontically induced tooth movement in the maxillary and mandibular arches between patients and the factors such as age, sex, and presence of an interference that might influence the amount of tooth displacement. METHODS By using a standardized experimental orthodontic tooth movement in 30 subjects, 57 premolars we...

Objective(s): Here we investigated the regulation of Th17 and Treg cells in orthodontic tooth movement during periodontal inflammation.Materials and Methods: Fifty-six SD rats were divided into a control (24 rats) and a tooth movement group during the recovery stage of periodontitis (RM group, 32 rats). Periodontitis was established by s...
