Plaque Minerals and Caries Experience: Associations and Interrelationships
TLDR
Inverse associations were demonstrated between DMFT and total calcium, phosphorus, magnesium, strontium, potassium, and fluoride concentrations in individual plaques, indicating the operation of a mineral level regulating mechanism, effective under diverse environmental conditions.
Betal chewing and caries experience in New Guinea.
TLDR
The results indicate that betel chewing confers a degree of protection against caries, and consistent inverse associations were demonstrated between caries experience and the intensity of betel eating for individuals and aggregates of subjects.
Associations between dental plaque and fluoride in human surface enamel.
Abstract In a study of caries in school-children in high and low fluoride areas, the amount of fluoride in samples of clinically normal surface enamel on the labial face of the upper permanent
Effect of pH on the fluoride ion activity of plaque.
TLDR
Following the pH decrease caused by fermentation, the fluid phase obtained by incubating plaque removed from subjects in a 1-ppm fluoride area was incubated in vitro with sucrose solutions.
Determination of saliva and dental plaque pH in hamsters with glass micro-electrodes.
Abstract Measurements of the pH of saliva, conjunctival fluid and dental plaques in situ were made in hamsters receiving a caries-conducive diet, by the use of glass microelectrodes specific for
Hydrogen ion activity in dental plaques of hamsters during metabolism of sucrose, glucose and fructose.
TLDR
The relative ability of these carbohydrates to serve as substrates for acid production did not correlate with their reported relative efficacy as cariogenic dietary substrates, indicating that additional factors are involved in the development of caries in the hamster.
Associations between fluoride concentration in successive layers of human enamel and individual dental caries experience.
TLDR
The results suggest that surface samples confuse the relation between caries experience and the internal F content of enamel, which could explain 32–45 per cent of variation in DMFT could be explained in terms of variations in the F content in enamel.
Survival of crowns and bridges related to luting cements.
TLDR
The longevity of 782 items of crown and bridgework was investigated in a retrospective study using a survival analysis technique and analysis of the survival of crowns alone showed the same ranking of the cements compared with all restorations.
Caries Experience and the Mineral Content of Plaque in a Primitive Population in New Guinea
TLDR
A study of plaque minerals performed as part of a wider investigation of over 100 intraoral variables in relation to individual caries experience in a rural community in New South Wales, Australia suggests that high mineral content in plaque may confer a degree of protection against caries in Western populations.
