introduction: corticotomy-facilitated orthodontics provides a means for rapidly moving teeth purportedly with little damaging effects to the periodontium and with greatly reduced treatment time. the aim of this study was to enhance the orthodontic tooth movement by reducing the cortical bone layer (resistant to bone re-sorption relative to spongious bone) following erbium, chromium doped yttriu...
objectives: fluoxetine is a selective serotonin re-uptake inhibitor (ssri) widely used for depression, bipolar disorder, anxiety and obsessive-compulsive disorder. the aim of this study was to assess the effect of fluoxetine on orthodontic tooth movement (otm) in rats. materials and methods: forty-five male wistar rats were randomly divided into three groups namely the control group (no medicat...
statins are used as cholesterol-lowering drugs by many patients and have been recently shown to affect bone metabolism. the aim of this study was to determine the effect of atorvastatinon on orthodontic tooth movement (otm) in rats.thirty-six adult male sprague-dawley rats were randomly divided into three groups of 12 samples each. group a, served as control with no medication while groups b an...
One of the most important concerns of patients is the need for orthodontic treatment, is the long duration of treatment and pain and discomfort during treatment.

Background and purpose: Low level lasers have been used in dentistry to stimulate orthodontic tooth movement and to inhibit the pain during tooth movements. Contradictory findings exist on this issue, therefore, this study evaluated the effect of laser therapy on pain during orthodontic tooth movement. Material and methods: In this clinical trial, 17 patients with extracted upper first premola...
The aim of this review article was to define the mechanism of action and effects of commonly used medications on the tissue remodeling and Orthodontic Tooth Movement (OTM). A review on the effects of medications and dietary supplements on the rate of experimental tooth movement was performed using Cochrane library, Embase and medline (1980-2013). 63 articles were included in this review. 34 o...
Background and Aim: Estrogen affects the metabolism in females. This study aimed to assess the effect of absence of estrogen on orthodontic tooth movement in rats. Materials and Methods: In this animal study, 55 rats were randomly divided into four groups. Group 1 (n=10) had intact ovaries. In group 2 (n=15), ovaries were intact but the rats were subjected to stress due to tooth preparation. I...
Background and Aim: Considering the effect of alcohol on bones, consuming alcohol may have some consequences on orthodontic tooth movement. The present study was aimed to evaluate the effect of alcohol consumption on bone density and orthodontic tooth movement in rats. Materials and Methods: In this experimental study, thirty rats were divided into three groups and underwent 3 weeks of diffe...
objective(s): to determine the effect of different doses of caffeine on orthodontic tooth movement (otm) in rats. materials and methods: forty male 250-300 g sprague-dawley rats were randomly divided into four groups of ten animals each and received 0 (control), 1 g/l, 2 g/l and 3 g/l caffeine in tap water for 3 days. orthodontic appliances were ligated between the maxillary first molars and in...
