Measuring the Disease Prevalence

1. The prevalence of periodontal diseases of the U.S. adult population is determined by clinical trials on sections groups using indexes. Indicators measure the quantity and severity of the disease. The indicators used to measure as gingivitis and periodontitis will vary with different epidemiological studies, as does the extent of the disease is present when the investigation begins. Cm. table 5-1 for a list of frequently used indicators for the evaluation of periodontal disease.

2. The prevalence impact of new cases (incidence), treats or deaths among the population, and the longer live actors.

3. Historically, gums indexes, the criteria used to measure the variables of inflammation, such as changing the color, the presence of edema, bleeding and when probing. Clinical indicators for measuring periodontal disease include such variables as the sounding depth, clinical attachments level (CAL), and interpretation of radiographic bone levels (BLs). Many studies use the sample groups numbering in the thousands. Several groups are compared and statistically analyzed. Epidemiologists will have different approaches to research and will include different variables in the research. Certain groups of the population, can be explored over time...
