Question 8

Use the following epidemiologic study to answer the following exercises.
In an epidemiologic study of periodontal disease, the dental hygienist identified a population of 100 individuals but could only select 50 for examination because of time and resource constraints.All of the individuals were to be examined within 2 weeks while they were visiting the local dental clinic.The dental hygienist planned to probe all teeth in each subject and set the definition of disease at one probe depth of 4 mm.The dental hygienist was also interested in identifying risk factors; therefore the subjects were questioned regarding age, socioeconomic status, and smoking status.Both men and women were included in the study and were in equal proportion in the population of 100.
