Dr. Ted’s Doctoral Dissertation completed (PhD,1971); Published 2001


In 1967 after Dr. Ted finished dental school (Temple, DDS, 1965), he was accepted to the Anthropology Department at the University of Pennsylvania and there earned his Doctorate degree--Doctor of Philosophy (PhD, 1971).

To earn that degree, Dr. Ted was required to write original research project. Since he wanted to become an orthodontist he chose to study a common orthodontic problem, one which had been studied many times previously – “buckteeth”—and still lacked an accurate answer.

Thirty years later that work has now been published. In the November issue of the American Journal of Orthodontics and Dentofacial Orthopedics, V. 120, n. 5, there appears Part II of an article representing the quintessential facts of my Doctoral PhD thesis completed in 1971. Part I of this thesis was also printed in the AJODO, March 2000.

Edward Angle, the “father” of Orthodontics put forth a belief that  “BuckTeeth” (about 25% of cases treated by orthodontists) were by and large caused by the lower jaw. He thought that lower jaw had to be smaller or pulled in and backward.

 Part I, V. 117, n. 3, of Dr. Ted’s work presents an imposing body of evidence to show that the lower jaw was in fact “normal” in size, form and position most of the time; the upper was most often the problem in that it was overgrown and excessively forward.      

Part II describes the amount and direction of growth of the teeth and jaws between 9.5 and 14.5 years of age for girls and boys. Moreover, there is presented actual-sized X-ray growth standard-norms for the head, jaws and teeth for boys and girls. These norms are used by other orthodontists to assess/diagnose the specific teeth and jaw problems of their new patients.

I invite you to peruse both of them. If you access AJODO online you may use my user/password: dr. ted rothstein/drted35, otherwise you can go directly to my website: www.drted.com:
