Nutrition, diet and dental health--de- and Remineralisation of Teeth
Therapeutische Umschau. Revue therapeutique, 2008Co-Authors: Thomas ImfeldAbstract:There is little if any evidence that nutrition during the time of tooth formation has any clinically significant effect on caries susceptibility of erupted Teeth in man. Caries, erosion and demastication are not nutritional diseases. They are, however, diet-related diseases because erupted Teeth are subject to local chemical and mechanical effects of the diet contacting the Teeth. Caries is the result of a chronic undermining demineralisation of the Teeth by organic acids that are produced by the bacteria of the dental biofilm while fermenting carbohydrates from the human diet. Dental erosion is the result of a chronic localised loss of dental hard tissue etched away from the surface by acids derived from the diet or from gastric reflux. The physicochemical grounds of de- and Remineralisation of Teeth are explained using detailed diagrams. Initial caries lesions without cavitation of the surface can remineralise (heal) under conditions of low cariogenic diet and good oral hygiene. However, once the surface has broken and cavitation occurred, there is no alternative to restorative dental therapy because Remineralisation is no more possible.

The ‘sialo–microbial–dental complex’ in oral health and disease
The Authors. Published by Elsevier GmbH, 2016Co-Authors: Kaidonis John, Townsend GrantAbstract:AbstractBiofilms are naturally found in all wet environments including the oral structures of nearly all species. Human oral biofilms have existed since our earliest ancestors and have evolved symbiotically with the dentition over many millennia within a Palaeolithic, hunter–gatherer setting. Irrespective of the plant–animal ratio, it can be argued that the Palaeolithic diet was essentially acidic, and acted as a selective force for much of the evolution of the stomatognathic system. The relationship between saliva, biofilm and Teeth, the ‘sialo–microbial–dental complex’, provides oral health benefits and offers a different perspective to the old dental paradigm that only associated oral biofilms (plaque) with disease (caries). This new paradigm emphasises that oral biofilms are essential for the ‘mineral maintenance’ of Teeth.Oral biofilms provide physical protection from dietary acid and together with bacterial metabolic acids cause the resting pH of the biofilm to fall below neutral. This is then followed by the re-establishment of a neutral environment by chemical interactions mediated by the saliva within the biofilm. Such pH fluctuations are often responsible for the cyclic demineralisation, then Remineralisation of Teeth, a process necessary for tooth maturation.However, since the advent of farming and especially since the industrial revolution, the increase in consumption of carbohydrates, refined sugars and acidic drinks has changed the ecology of biofilms. Biofilm biodiversity is significantly reduced together with a proliferation of acidogenic and aciduric organisms, tipping the balance of the ‘demin–remin’ cycle towards net mineral loss and hence caries. In addition, the consumption of acidic drinks in today's societies has removed the protective nature of the biofilm, leading to erosion.Erosion and caries are ‘modern-day’ diseases and reflect an imbalance within the oral biofilm resulting in the demineralisation of Teeth
