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.
How to Use a Clinometer. A clinometer is used to measure angles. This is the method used by foresters to measure the height of a tree. The clinometer only works for measuring height when the observer is standing exactly one chain length away from the tree (66â or 100 links). A âchainâ is a unit of measure unique to forestry and dates back to the use of chains to drag felled trees out of the forest. 1. To use the clinometer, pinch the brass ring between your thumb and forefinger and look through the black eye piece using only one eye. If possible, the other eye should be looking at the tree. In the eyepiece you will see a black line and a scale. The right side of the scale is the height reading, the left is % slope. You want to read the right side of the scale. a. Tilt your head until the black line is on the base of the tree and read and remember the number where the black line crosses the right hand side of the scale.
