The purposes of this study were to determine by direct measurement the effects that acetylsalicylic acid, ibuprofen, and acetaminophen have on orthodontic tooth movement in rats and to evaluate histologically the differences in bone resorption in the pressure area in rats treated with these analgesics.ooth movement was similar in the groups. CONCLUSIONS: The results indicate that nonsteroidal anti-inflammatory analgesics such as aspirin and ibuprofen diminish the number of osteoclasts, probably by inhibiting the secretion of prostaglandins, thereby reducing orthodontic tooth movement.
â¢ CLINOMETER (noun) The noun CLINOMETER has 1 sense: 1. an instrument used by surveyors in order to measure an angle of inclination or elevation. Familiarity information: CLINOMETER used as a noun is very rare.
A true-rms device (rms = root mean square) is one of three tools that can measure alternating current (ac) or ac voltage: 1  True-rms digital multimeters (or clamp meter).2  Average-responding digital multimeter (or clamp meter). more sophisticated true-rms meter can accurately measure both pure waves and the more complex nonsinusoidal waves. Waveforms can be distorted by nonlinear loads such as variable speed drives or computers. An averaging meter attempting to measure distorted waves can be up to 40% low or 10% high in its calculations.
