Scenario 6:A dental hygienist compares two studies on smoking and periodontitis in rates in 20- 64-year-old males. Both studies used similar methodology and used the Global Adult Tobacco Survey (GATS), a 6-item survey assessing cigarette consumption paired with a Periodontal Disease Index (PDI) using Ramfjord teeth and radiographs. Study A is a systematic review with meta-analysis of 14 cohort studies showing smokers have an 85% higher risk (RR=1.85). Study B is a cross-sectional survey of 200 patients linking smoking to periodontal disease.
