What makes dentists tick? How much do they earn? What are the most commonly performed procedures? What's the scoop on professional associations? These and other questions are answered in a spate of research reports recently released by Research and Markets, an Ireland-based market research firm. The studies cover a wide range of American dental subjects, from surveys of dental services rendered, to in-depth analysis of dental practices, to reports scrutinizing dental education in the U.S. Most of the reports are packed with dozens of detailed tables.
