Consequently, this results in an increased caries prevalence. [12] Dental caries is a process in which enamel is dissolved by acid producing bacteria. In 2004–2006, the average DMFT (decayed, missing and filled teeth) for adults in Australia over the age of 65 was found to be 23.7%. [12]
Dental caries result when the demineralization rate is faster than the remineralization, producing net mineral loss, which occurs when there is an ecologic shift within the dental biofilm from a balanced population of microorganisms to a population that produces acids and can survive in an acid environment.
This index is based on in-field clinical examination of individuals by using a probe, mirror and cotton rolls, and simply counts the number of decayed, missing (due to caries only) and restored teeth. Another version proposed in 1931 [1] counts each affected surface, yielding a decayed, missing, and filled surfaces (DMFS) index. Statistics are ...
The decaying tooth root provides bacteria with an enclosed environment with low oxygen content. Consequently, the obligate and facultative anaerobes present within the oral cavity flourish and outcompete the other bacteria at the site of tooth decay, causing the dental caries to escalate into a mouth infection.
Enamel hypoplasia is a risk factor for dental caries in children including early childhood caries (ECC), which continues to be a burden for many children. This association has been identified as significant and independent, and is believed that the formation of pits and missing enamel provides a suitable local environment for adhesion and ...
Ecological plaque hypothesis and the aetiology of dental caries The ecological plaque hypothesis, a combination of the two previously mentioned hypotheses, suggests that there are certain species responsible for pathology, but are present in insufficient quantities to cause damage to a healthy individual.

This can lead to a weakened enamel surface that is more porous, thinner, prone to pits and grooves which raises the risk of dental caries and sensitivity. An oral examination is being held and can be observed through the image. Up above is the dental operating microscope where enamel infractions can be observed.
Dental caries is a dental biofilm-related oral disease associated with increased consumption of dietary sugar and fermentable carbohydrates. When dental biofilms remain on tooth surfaces, along with frequent exposure to sugars, acidogenic bacteria (members of dental biofilms) will metabolize the sugars to organic acids.
