Effects of steroidal and nonsteroidal drugs on tooth movement and root resorption in the rat molar.
OBJECTIVE To test the hypothesis that the administration of aspirin, acetaminophen, meloxicam, celecoxib, and prednisolone have no effect on root resorption and tooth movement. MATERIALS AND METHODS A mesial force of 50 g was applied to the left maxillary first molars of sixty 10-week-old male Wistar rats using nickel titanium closed coil springs attached to the cervical area of the incisors....
متن کاملForce magnitude and duration effects on amount of tooth movement and root resorption in the rat molar.
OBJECTIVE To test the hypothesis that there is no difference in the effect of different continuous moderate to very heavy forces on root resorption or amount of tooth movement. MATERIALS AND METHODS In the study, 10, 25, 50 and 100 g mesial force were applied to the maxillary first molars of rat using nickel titanium closed-coil springs for 3 days, 14 days, and 28 days. The molars were extrac...
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 کاملsystemic effects of fl uoxetine on the amount of tooth movement,root resorption, and alveolar bone remodeling during orthodontic force application in rat
background: antidepressant drugs such as fl uoxetine are of the most commonly used drugs among the public. these drugs may impact the regulation of bone cell functioning, and thus affect orthodontic tooth movement. the aim of this study was to determine the effect of fl uoxetine on tooth movements during orthodontic treatment in rats. materials and methods: in this study, 30 male rats were rand...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
