Anatomic Crown and Root
By Gail Bohlman
Students locate the enamel, cementum, cementoenamel junction, the anatomic crown, and the root of a tooth in this interactive lesson.
Learners read about audiological tests including pure tone testing, air conduction, bone conduction, Speech Reception Threshold, and Speech Discrimination Score. They listen to sounds and words recorded at different decibel levels and see a graphic representation of decibel ranges. A brief review concludes the activity.
