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.
Thus the angle in the diagram above can be expressed as 45Ë or 1.0 (ratio) or 100%. To measure slope inclination in the field we use a clinometer (Suunto is the most common make). This device provides measures in both degrees and percent. 21.2 m / cos [ 32 ]. = 25 m. Measures of slope in degrees are useful for converting slope distance to horizontal distance, but percent is easier to use to calculate change in elevation. Remember that tan is slope is expressed as a ratio ...
