The American Association of Orthodontists study of the availability of orthodontic services
T
he quality and the availability of orthodontic health care are dependent on the regional balance between those with the need and desire for the service and those who are qualified to provide it. The AA0 in past years was deeply concerned with the developing shortage of orthodontists to provide for the growth population of the postwar baby boom and actively worked with thr dental schools to increase training programs. The available educational openings have now more than doubled. In 1974 the AA0 House of Delegates created a special committee to study orthodontic manpower needs and to determine the effects on orthodontic practice of the decline in the birth rate, third party programs, orthodontic treatment by those not specialists in orthodontics, and closed panels. The first portion of this committee’s report, beginning with the 1974 manpower study and a comparison of orthodontists and 12-year-old populations, was presented to the 1975 House of Delegates and approved for publication by the Board of Trustees. The second portion of the report dealing with the actual utilization of orthodontic services, the effects of third party programs, and closed panels will be presented to the 1976 House of I jelegates. The committee is composed of one representative of each constituent society and a consultant from the Board of Trustees. The statistical consultant was Dr. Ik Whan Kwon of Saint Louis University. The committee consists of the following : Robert L. Williams (Chairman), Midwestern Society Douglas J. Shilliday, Great Lakes Society William Kress, Middle Atlantic Society Stewart L. Thompson, Northeastern Society Eugene W. Supernaw, Pacific Coast Society Earl N. Seavall, Rocky Mountain Society Horace I). Wilder, Southern Society W. Kenneth Thurmond, Southwestern Society Raymond C. Thurow, Consultant, Trustee 326

results
On Nov. 8, 1974, 5,621 questionnaires were mailed to all of the active and associate members of the Association. There were 4,028 usable returns; this represents 72.1 per cent (United States) and 60.2 per cent (Canadian) of the total number sent. Statistical considerations 1. The rate of return is good. 2. This is a valid survey, and the results are statistically significant. 3. Returns from the United States and Canada exhibit a wide variation. Therefore, Canadian returns are presented separately. 4. There was no significant variation between the returns from the eight constituent societies. 5. A similar survey was conducted in 1972. Where applicable, those figures are included for comparison, Results

survey,
Part
B
This study reports on the number of orthodontists who will be in practice and the number of 12-year-old children who will reside in the United States for each year through 1982. The survey is based upon the following assumptions : 1. The number of orthodontists entering practice each year remains the same as it is currently (approximately 350). 2. The orthodontist retirement and death rate remains constant (0.546% per year).

he quality and the availability of orthodontic health care are dependent on the regional balance between those with the need and desire for the service and those who are qualified to provide it. The AA0 in past years was deeply concerned with the developing shortage of orthodontists to provide for the growth population of the postwar baby boom and actively worked with thr dental schools to increase training programs. The available educational openings have now more than doubled. In 1974 the AA0 House of Delegates created a special committee to study orthodontic manpower needs and to determine the effects on orthodontic practice of the decline in the birth rate, third party programs, orthodontic treatment by those not specialists in orthodontics, and closed panels. The first portion of this committee’s report, beginning with the 1974 manpower study and a comparison of orthodontists and 12-year-old populations, was presented to the 1975 House of Delegates and approved for publication by the Board of Trustees. The second portion of the report dealing with the actual utilization of orthodontic services, the effects of third party programs, and closed panels will be presented to the 1976 House of I jelegates. The committee is composed of one representative of each constituent society and a consultant from the Board of Trustees. The statistical consultant was Dr. Ik Whan Kwon of Saint Louis University. The committee consists of the following : Robert L. Williams (Chairman), Midwestern Society Douglas J. Shilliday, Great Lakes Society William Kress, Middle Atlantic Society Stewart L. Thompson, Northeastern Society Eugene W. Supernaw, Pacific Coast Society Earl N. Seavall, Rocky Mountain Society Horace I). Wilder, Southern Society W.

results
On Nov. 8, 1974, 5,621 questionnaires were mailed to all of the active and associate members of the Association. There were 4,028 usable returns; this represents 72.1 per cent (United States) and 60.2 per cent (Canadian) of the total number sent. Statistical considerations 1. The rate of return is good. 2. This is a valid survey, and the results are statistically significant. 3. Returns from the United States and Canada exhibit a wide variation. Therefore, Canadian returns are presented separately. 4. There was no significant variation between the returns from the eight constituent societies. 5. A similar survey was conducted in 1972. Where applicable, those figures are included for comparison, Results
