    1. Number of roots
    2. Degree of Alveolar Bone loss
    3. Degree of Root Resorptio

ANCHORAGE:    It is the Resistance to Unwanted Tooth Movement

Theme and atmosphere

The main idea is the story of a ghost living tormenting the inhabitants of an English manor. The ideas range from minor's own ghost story to life of every single inhabitant of the mansion.

Bill Gates likes Salman Khan a lot, so much so that the Bill and Melinda Gates Foundation is streaming cash to his Khan Academy, an internet silo of over 2,100 free, downloadable video tutorials on Calculus, Physics, Organic Chemistry, et al.

So is the Khan video approach a “disruptive technology” which undermines the existing deathbed educational model by doing it faster, better, and cheaper? Mr. Gates thinks so. “It’s a revolution,” he enthuses. “Everyone should check it out.” (www.khanacademy.... Continue reading "Bill gates" »
