ADA & Thomson PDR Strive to Increase Patient Safety with the Dental Therapeutics Guide

05/17/2006

Montvale, New Jersey, - The American Dental Association (ADA) is partnering with Thomson PDR to publish The ADA/PDR® Guide to Dental Therapeutics, 4th Edition. The ADA is the largest and oldest association of dentists in the U.S.. PDR, a part of the Thomson Corporation (NYSE:TOC; TSX:TOC), provides authoritative drug information and integrated information tools to healthcare professionals worldwide.

Written by a team of experts, the Dental Therapeutics Guide includes the work of dentistry’s leading academicians and clinicians. It is edited by Sebastian G. Ciancio, D.D.S., distinguished service professor and chair, department of periodontics and endodontics, University of Buffalo, SUNY.

“We are very pleased to collaborate with Thomson PDR, and be able to bring our profession’s unique perspective and latest clinical information to the guide,” says James B. Bramson, D.D.S., ADA executive director. “We also view this collaboration as an opportunity for ongoing enhancements to the publication to continually provide the dentist with the latest patient-care information in a readily accessible format.”

"It is noteworthy that this book has been prepared at the request of the ADA Council on Scientific Affairs and is the only dental therapeutics book published by the ADA,” says Dr. Ciancio. “This provides dentists with timely information on making the best medication decisions for patients.”

The guide has undergone a redesign for rapid access of critical information needed to treat patients. For easier searches, the content is in three sections: Drugs Used in Dentistry, Drugs Used in Medicine, and Drug Issues in Dental Practice.

The ADA and Thomson PDR are discussing additional print and electronic products that will enable dentists to provide better care for their patients.

“The high quality, clinically relevant information from the American Dental Association is a perfect match for the PDR drug information solution set”, said Kevin Sanborn, executive vice president of Thomson Healthcare in charge of PDR products and solutions. “By working together, we’re putting the most relevant clinical information into the hands of dentists who administer patient care.”

The Guide to Dental Therapeutics, 4th Edition will be available in September 2006.
