Assumptions concerning orthodontic diagnosis and treatment

Treatment results obtained by one orthodontist cannot be completely appreciated by another unless their concept of the normal is identical.

Orthodontic results speak for themselves. It is the assumptions upon which the diagnosis and methods, of treatment are based and the interpretations of what changes occurred to achieve the desired result that may be questioned.

Judicious extraction is permissible as a part of orthodontic treatment provided it is based on the actual rather than the assumed conditions of the case.

Those who teach orthodontics or contribute to its literature must constantly remember that they assume an enormous responsibility.

Research must be carefully executed and correctly interpreted or it can do more harm than good.

Students should be trained to analyze intelligently and to criticize constructively all that is said and written in the field of orthodontics and allied subjects.

When the subject matter is one in which the student or orthodontist has insufficient background, he should turn to one better prepared for his analysis and criticism.

There is a decided need for logic and consistent thinking in much of the orthodontic literature.

It is possible to prove almost any given thesis by quotations from the literature, but this does not substantiate its validity.

Change usually denotes progress, and it can in orthodontics, providing such change is based upon proved facts and not upon unreasoned and unreasonable assumptions.
