The Periodontal Membrane in Orthodontics

Abstract

the use of an operating stool will add several years of service to the life of the average dentist, we are suggesting that it be used about 50 per cent of the time. “One of the most constructive sugges­ tions for the profession to come out of a dental school in a long time,” and “Wish I had had the opportunity while a stu­ dent in school to have been trained to operate from a stool,” were two of the most common remarks received from practitioners. While it is recognized that many fac­ tors can contribute to the production of fatigue of the dentist, the matter of pos­ ture has not received all of the attention that it should. It seems not so much a matter of either sitting or standing as it does of changing one’s position at the chair, thus resting one group of muscles, while another works. To accomplish this purpose, it becomes necessary to learn to operate while sitting as well as while standing. It is with this objective in mind that Northwestern University has em­ barked on a program of providing the facilities whereby the student can learn to do both. It seems reasonable to con­ clude that by helping the student to op­ erate with greater relaxation, both the dental profession and the public are benefited.—25 E. Washington Street.
