Constant versus dissipating forces in orthodontics: the effect on initial tooth movement and root resorption.
The aim of this clinical and confocal laser scanning microscopic study was to compare the effects of two frequently used archwires on tooth movement and root resorption. A total of 84 premolars in 27 individuals (10 boys, 17 girls, with a mean age of 12.5 years) was moved buccally with an experimental fixed orthodontic appliance. In a split mouth experimental design the premolar on one side was...
متن کاملThe Effect of Ovariectomy and Orchiectomy on Orthodontic Tooth Movement and Root Resorption in Wistar Rats.
STATEMENT OF THE PROBLEM Root resorption (RR) after orthodontic tooth movement (OTM) is known as a multifactorial complication of orthodontic treatments. Hormonal deficiencies and their effect on bone turnover are reported to have influences on the rate of tooth movement and root resorption. PURPOSE This study was designed to evaluate the effect of female and male steroid sex hormones on toot...
متن کاملthe effect of celecoxib on orthodontic tooth movement and root resorption in rat.
inhibition of prostaglandin (pgs) production leads to decrease in orthodontic tooth movement (otm). it is not known whether inhibition of cyclooxygenase-1 (cox-1) or cyclooxygenase-2 (cox-2) is the key mechanism for this effect. in this study, the effect of celecoxib, a highly-selective cox-2 inhibitor, was investigated on otm in rats.four groups of male rats (seven animals in each goup) were u...
متن کاملTooth movement and root resorption; the effect of ovariectomy on orthodontic force application in rats.
OBJECTIVE To quantify the amount of tooth movement and orthodontically induced root resorption (OIRR) in ovariectomized rats. MATERIALS AND METHODS Five 10-week-old female Wistar rats undergoing ovariectomy (OVX) were investigated as the experimental group, and the other five without ovariectomy served as the control group. Four weeks after ovariectomy, 25-g nickel-titanium closed-coil spring...
متن کاملThe Effect of Celecoxib on Orthodontic Tooth Movement and Root Resorption in Rat
OBJECTIVE Inhibition of prostaglandin (PGs) production leads to decrease in orthodontic tooth movement (OTM). It is not known whether inhibition of cyclooxygenase-1 (COX-1) or cyclooxygenase-2 (COX-2) is the key mechanism for this effect. In this study, the effect of celecoxib, a highly-selective COX-2 inhibitor, was investigated on OTM in rats. MATERIALS AND METHODS Four groups of male rats ...
