“In the light of the facts as to the local etiological and pathological conditions in each of these two diseases, they can not be entirely prevented unless this particular method of personal oral hygiene is followed. It differs substantially from, and in vital particulars it is quite the opposite of, methods generally advocated3 and followed.”
“Dentists can pass on to their patients only such advice and information as they themselves know. A dentist cannot be expected to successfully teach his patients effective personal oral hygiene, and influence them to follow it, if he does not know it and follow it himself.”
“Conclusions drawn from clinical trials of measures, remedies and procedures for the prevention and control of the principal diseases of the teeth are of limited use and often confusing and misleading. Clinical diagnosis and observations are concerned with the advanced (diagnosable) stages of the respective diseases and do not take into account the earlier stages.”
