DENTAL DISEASE

POSITION IN NEW ZEALAND THE CAUSES OF DECAY “What causes dental decay?” This is a question which is often raised. While there is still need for further research on this subject, there are different theories advanced, states an article from a dental clinic. An accepted theory is that which is called “Miller's Chemico Parasitic Theory,” wherein it is that the onset of d'ecay is due to carbohydrates left in the mouth and fermenting to make acid. Lactic acid penetrates the enamel until a cavity is made and is large enough to reach the dentine which forms the bulk of the tooth. Mouth bacteria then begin their decaying processes. This theory advanced deals with the exciting cause of dental caries. Besides an exciting cause there are predisposing causes. Irregularities of the teeth, lack of pre- and post-natal care, poor health, poor diet, oral sepsis and an hereditary predisposition are some of these.

New Zealanders are apt to talk glibly of the cause of dental disease lying in the lack of “something” in the soil or water. Whatever it may be, much can be done to raise the standard from GUI by destroying that defeatist. attitude and substituting for it one of “healthy” interest.
