Study Notes

Dental Caries

Populations consuming water with approximately 1 ppm of fluoride demonstrate 50-65% less caries than comparable non-fluoride populations.
Caries levels increase with age and remain problematic in adults despite recent declines in caries among children.

Assessing Dental Caries

The DMF index is a standard method for assessing dental caries experience in populations.
DMF stands for Decayed, Missing, and Filled.
The DMF index is used to describe the status of an individual or group with respect to a condition being measured.

DMF Index

The DMF index has been used for almost 80 years and is well established as the key measure of caries experience in dental epidemiology.
The DMF index is applied to the permanent dentition and is expressed as the total number of teeth or surfaces that are decayed (D), missing (M), or filled (F) in an individual.
The DMFT index is used when the index is applied to teeth specifically, and scores per individual can range from 0 to 28 or 32, depending on whether the third molars are included in the scoring.
The DMFS index is used when the index is applied only to tooth surfaces, and scores per individual can range from 0 to 128 or 148, depending on whether the third molars are included in the scoring.
The dmf index (in lowercase letters) is a variation that is applied to the primary dentition.

Definitions

Incidence: the number of new cases of a disease or disorder in a population over a period of time.
Prevalence: the number of existing cases of a disease in a population at a given time.
Trends: used to describe the prognosis or course of a symptom, disease or methods of disease management.

Previous Studies in Dental Caries

Dental caries is the most common dental disease in the world and is the primary cause of tooth loss.
Dental caries has been making people miserable since at least the time when humans began to develop agriculture.
Historical findings have shown that tooth decay emerged as an important disease in the population.
The expansion of sugar consumption in the 16th and 17th century helps explain the change in the global scenario and the epidemic levels in more developed regions.
A quantitative measure of the tendency of populations to develop dental caries is essential in delineating the magnitude of the problem, recognizing the pattern of the disease, studying underlying causative factors, and assessing the effectiveness of preventive measures.
