and McDonald’s in popular culture? After all, America does have the most sophisticated advertising and marketing in the world. We can sell Coke to Mongolian yogurt eaters, so why not health to fast food junkies? What would it mean to the world, given that what America does first, the rest of the world inevitably picks up later? One example of what I have in mind is the vastly improved dental caries incidence in the western world that is the result of cooperation among profes sionals (dentists and scientists), governments (water fluorida tion), industry (toothpaste, toothbrush and mouthwash makers) and our popular culture’s standards of dental beauty and fresh breath (the way to be, which is healthy).

dentistry, on compliance with the bloodborne pathogens standard. In this video, the application of rubber dam was shown three times in the dental setting. Dental dam is also specifically stated in the OSHA regulations as an optional device, combined with the use of high-volume evacuation, to minimize circulation of bloodborne pathogens. The procedure of the appli cation of dental dam is taught at every dental university in the United States. It is simple for the dentist to use and offers many benefits to their practice. Why doesn’t the ADA support dental dam as a vital part of infection control procedures as it does gloves, masks, gowns, handpiece sterilization, etc.? Thomas E.

WHY NO DENTAL. DAM?
I just finished reading the “OSHA Compliance Check List” for the dental office prepared by the ADA and distributed to its members [through the Jan. 18 ADA News], The subject of the OSHA Check List was compliance with the OSHA bloodborne pathogens standard. In general, [the Check List] is informative and useful to the dentist. We wonder why dental dam was not recommended in this publication to reduce the circulation of bloodborne pathogens, as studies prove a 98 percent reduction when used. Coincidentally, this very same week, I had an oppor tunity to review the video produced by OSHA and intended to assist professionals in various fields, including 16
JADA, Vol. 124, April 1993
E d ito r’s note: Mr. Chap- » man, the ADA does support the use of dental dam. ADA informational materials on infection control contain frequent references to the use and advantages of dental dam as a barrier to the spread of microorganisms. The lack of inclusion of dental dam in the ADA/OSHA Compliance Check List was neither an oversight nor a slight to dental dam’s effective ness. The OSHA Check List was designed specifically to address only the federal agency’s requirements. Dental dam is not among those requirements. The effectiveness of dental dam in reducing the spread of bloodborne pathogens has been well documented in this Journal. A product that can
provide a barrier that is 98 percent effective should find greater use by the dental practitioner. By including dental dam in its infection control publications, the ADA has demonstrated its support for this product. DELEGATING DUTIES
Dr. Gordon Christensen’s article, “The Cracked Tooth Syndrome” (February), gives me cause to feel uneasy. As a practicing dentist, I have been confronted with the seemingly impossible task of diagnosing the true cause of periodic and intermittent tooth pain. I have been confronted with the problem for over 30 years, and continue to expect similar diagnostic confronta tions on a daily basis for as long as I continue to practice. I couldn’t agree more with Dr. Christensen’s observation that diagnosing the severity of a cracked tooth is nearly impossible. Likewise, I couldn’t disagree more with his direction that “it is advisable to instruct assistants and dental hygienists in the use of diagnostic tools for the purpose of identifying a tooth with a cracked cusp.” It is purely the dentist’s professional responsibility to perform the full gamut of appropriate diagnostic tests to determine the cause of a perceived problem, and there after to make the logical treatment recommendations for its resolution. Delegating to an auxiliary the performance of a task that plays a role in making a differential diagnosis is an abrogation of the doctor’s professional responsibility. Certain state dental practice acts prohibit the making of a diagnosis by an auxiliary, as
