The connection of the teeth to overall health and efficiency was appreciated in a way that was general long before vitamins or focal infections had been heard of. Toothaches used to be as inevitable as coughing, and horse traders and slave buyers inspected the teeth of the purchases. But in recent times has attention been given to the preservation and the care of their teeth.
Early studies of the cause and prevention of dental caries suggested there might be one causative factor but farther results show that the challenge is a complex one, with diet, heredity, internal secretions, mechanical aspects, and oral hygiene of greatest importance.
Diet and Dental Caries
There is now general agreement that diet probably is the most important single factor in the maintenance of sound, healthy teeth, and that an adequate diet is the most crucial during the period of most rapid growth. McCullum and Simmonds conclude from an experimental study that rats which are kept to a diet during part of the developing period have decay that is early and poor teeth, although an adequate diet is supplied later. In today before viosterol was developed and before cod-liver oil was widely used, McCullum also reported that at the age of entering faculty 9 percent of children who had been breastfed for at least 6 weeks had dental caries, 22 percent of children who were fed on cow’s milk or about milk mixtures, and 27 percent who had been fed on oatmeal water and other prepared foods. This would demonstrate that the foundation of health is put early in life, but it now appears that the period is also of value in this aspect. The emphasis is now being put upon a proper diet during pregnancy. orangeville ontario dentist
Significant though diet is, that does not seem to be any single dietary component which is responsible for dental caries. Calcium and phosphorus, both minerals found in teeth and bones, and vitamin D, which regulates the use of those minerals from the body, are obviously crucial. Of these, calcium and vitamin D were first thought to be of greatest importance: but the work seems to indicate that phosphorus is of as good if not greater significance than calcium. Fish foods, certain vegetables, and milk are rich sources of calcium and phosphorus. Vitamin D is very likely to be deficient during the winter months in natural foods but is readily administered in the kind of vitamin D, D cod-liver oil, or viosterol.
Children have long been denied candy due to the belief that sugar is related to dental decay, and certain studies completed in institutions for orphans where the diet is rigorously controlled suggest the incidence of dental caries is directly associated with the total amount of carbohydrate from the diet. Cereals from which the hull of the grain has been removed appear to have a negative influence upon the evolution of the teeth, and investigators think that oatmeal leads to the formation of caries.
Divergent opinions concerning the relation of diet to dental health leave one rather perplexed. No one dietary element is responsible for resistance to caries, but different elements are necessary for the correct development and ongoing soundness of tooth. For practical purposes, a well-rounded diet, containing some form of vitamin D or liberal amounts of milk, orange juice, fresh fruits, vegetables, and for kids cod-liver oil, may be depended on to supply the nutritional requirements of the tooth.
It is often said that”a clean tooth never decays.” Whether or not this is accurate depends upon the definition of cleanliness. The announcement is correct if cleanliness implies freedom from bacteria. But at the food we consume and with germs within the mouth, it’s impossible to have the teeth clean.
The mechanism of decay is via the activity of acids made by bacterial decomposition of meals, first upon the tooth and then on the softer dentine of the tooth. The activity of the acid upon the tooth arrangement can begin in any crevice, irregularity, or fracture in the enamel. The amount of acid and decomposition formation is best when there are gross accumulations of food substances. In fact, it is between the teeth, in which it’s difficult to prevent accumulations of meals that decay frequently begins. Therefore, although cleanliness of the teeth is the sole element in the prevention of dental decay, as well as the one it’s not without importance.
Some clarification of the part of the issue was given by current studies of the bacteria within the mouth. If a particular germ called Lactobacillus acidophilus occurs in quantity caries develop with wonderful rapidity. This is because these bacteria act upon carbohydrates on and about the teeth. These studies have proven that if persons have an excessive number of lactobacilli in their mouths, then the number of caries can be reduced by the elimination of sugars and other carbohydrates from the diet.
It currently appears that certain chemicals applied to the teeth may neutralize the acids formed by the activity of germs upon carbs and therefore reduce caries. A number of the chemicals are now being included in so-called”ammoniated” toothpaste.
Fluorine and Dental Caries
During the past many years investigations have taken a different turn. It had been determined that the chemical distinction between carious and non-carious teeth is that carious teeth contain less fluorine, an element that’s present in minute quantities in teeth and the bones. This was followed by an investigation of the fluorine content of their drinking water in areas in and regions in. A difference in fluorine content has been discovered. From such studies, it’s been reasoned that the existence of roughly 1 part of fluorine per 1,000,000 components of drinking water causes a decreased prevalence of caries. Fluorine inside this amount induces some mottling of the teeth.
Proceeding on the basis of the information, several researchers have experimented with the use of fluorine into the face of the teeth of children. Within this analysis, Knutson and Armstrong reported that the use of 2 percent sodium fluoride solution into the teeth resulted in 40 percent caries over a span of a year in 289 children than grown in 326 untreated controls. No healing effect was noted on teeth where caries existed. This use of fluorine for the prevention of dental caries is a promising line of investigation but it’s still at the experimental stage.
Other exceptionally significant studies are the ones in which sodium fluoride in minute quantities has been added to the water supplies of many cities which have low fluoride content. If this should prove successful in preventing caries, then it’ll be a fantastic step in the control of this prevalent of human diseases.
That other elements play a role in determining the health of teeth is evident from the fact that a number of persons remain immune from caries no matter how unbalanced the diet or just how damaging the mouth, while others develop caries through the diet plan, as far as we could tell, is entirely adequate and the upkeep of the mouth perfect. One of those additional factors will be heredity, and the operation of the glands of internal secretion might be another.
