The standards by which alot of folks go by are some of the following:
Journal of the American Dental Association
Journal of the Academy of General Dentistry
Clinical Research Associates review (Gordon Christensan's product review newslettter)
Journal of Prosthetic Dentistry
Compendium (Peer reviewed articles)
Contemporary Esthetic Dentistry (A quazi peer reviewed show and tell "journal" funded by dental product companies which does from time to time hit on some current hot topics)
Dental Finance (some good interviews conducted by one of the current "guru's", David Hornbrook)
Some basic starter topics to look for currently would be:
1 step self etching primers/adhesives
Dentists vs Dental Insurance companies
Dental access for the underserved populations
Anti carries vaccines
and certainly not last.....
The great amalgam debate <img border="0" title="" alt="[Eek!]" src="eek.gif" /> <img border="0" alt="[Wowie]" title="" src="graemlins/wowie.gif" />
