1. 1. Inquiry has been made into the teaching of orthodontics in Australia, and also into the prescribed textbooks. 2. 2. It has been found that a considerable part of the theory which is being taught is unscientific, and it is inconsistent with that of physics, physiology, and pathology. 3. 3. Various improvements in the teaching of the theory of orthodontics have been submitted. 4. 4. Ambiguous and otherwise inappropriate terms are generally used, which are not clearly defined. More suitable terms have been recommended. 5. 5. Suggestions have been made for the clarification of the general view of normal dental occlusion, and of dental malocclusion, and also for the improvement of the standard classification of cases of dental malocclusion. 6. 6. In Australian dental schools, the teaching of the immediate background of orthodontics is adequate, but there is absence of the subjects of the remote background from the syllabus. 7. 7. The textbooks on orthodontics, in general, exhibit the obvious need for the condensation and the logical arrangement of the text.
