What is epidemiology in caries?
Dental caries is a preventable, behavioural/life-style disease that is age related and life-long. Preventing dental caries should start at mother-and-child clinics in conjunction with the available educational and health care programmes. Oral health (caries) epidemiological surveys should be held periodically.
What is the practical significance of the epidemiology of dental caries?
Dental caries and periodontal disease are one of the major public health problem, therefore epidemiological studies are useful for identifying and monitoring their prevalence among different age and geographical groups, giving new treatment perspectives.
What is a Stephan curve?
The Stephan Curve is a graph that shows what happens after the consumption of sugar in relation to dental caries. After sugar intake, demineralisation of the tooth surfaces takes place due to the drop in pH as the bacteria in the mouth convert the sugar to acid.
What are the prevention of dental caries?
To prevent dental caries there are four main principles: oral hygiene; healthy eating advice; increasing fluoride availability; and placement of fissure sealants. Dental health education (ie information giving) is most beneficial on a one-to-one basis, and within the dental setting.
What are the classification of dental caries?
In some instances, caries is described in other ways that might indicate the cause. Usually it simply can be divided into five tooth surfaces: occlusal side, labial side (buccal side),lingual side (palatal side), mesial side, and distal side.
How do you calculate prevalence of dental caries?
To calculate the prevalence of dmft in primary teeth, the sum of dmft was divided by the sample size of 6-9-year-old children. The same procedure was carried out to calculate the DMFT for permanent teeth for age between 10-12 years.
What is the critical pH of dentine?
For this reason, care should be taken to formulate these products with safe pH values for both enamel and root dentin which, based on specific formulation, should be around 6.7 or higher.
What is sugar clock?
An important factor in the prevention of dental caries is limiting the number of times in a day that sugar enters the mouth. It was concluded that the sugar clock is an effective method of teaching the importance of limiting frequency of sugar intake to this age group.
What are the types of dental caries?
There are 2 types of caries, depending on the course of the process: acute; chronic.
What is the main cause of dental caries?
Cavities are permanently damaged areas in the hard surface of your teeth that develop into tiny openings or holes. Cavities, also called tooth decay or caries, are caused by a combination of factors, including bacteria in your mouth, frequent snacking, sipping sugary drinks and not cleaning your teeth well.
Which is the most important risk factor for dental caries?
Patient on medication which causes hypo-salivation
What are the causes of dental caries?
Advancing age (older teeth form plaque more quickly)
