Interest in bleaching teeth has grown exponentially in the last few years and is set to increase dramatically again in the future as new markets become available and stimulate further product development. This guide is written to help the busy restorative dentist who needs to keep up to date with the types of product available, the techniques to use them effectively and safely, and how to use them in combination with restorative dentistry in treating patients.
Believing that sufficient and well-deserved prominence was not being given to the use of tin foil and its
combinations, the author decided to present a brief historical résumé of the subject, together with such
practical information as he possesses, before the profession in order that it may have the satisfaction of saving
more teeth, since that is the pre-eminent function of the modern dentist.
Surveys new techniques and chemicals for bleaching teeth that are now being tested by dentists and people at home. Among the topics are diagnosis and treatment planning, materials and their evaluation, clinical and laboratory techniques, and marketing.
Since the last issue on temporomandibular (TMD) disorders and orofacial
pain presented in the Dental Clinics of North America (April 1997), there
has been an explosion of scientific, technologic, and procedural advances in
this complex field. The amalgamation of the science with the art of dentistry
has resulted from an enhanced appreciation for and the ability to provide
evidence-based diagnosis and care.
Pain and compromised function are the most common reasons for which
people seek health care.
The history of internal bleaching can be traced back more than a century. Chloride was first used inside the pulp chamber as an
internal bleaching agent, but the results were not efficacious. In 1958, Pearson was impressed by the positive bleaching effect of 30%
hydrogen peroxide on the external surface of teeth.
The solution was used internally on a pulpless tooth for 3 days with great
success. In 1961, Spasser mixed sodium perborate and water as an internal bleaching medium and placed the mixture into the tooth,
employing interval appointments.
