COMMUNITY TESTLET: Use the fоllоwing testlet tо аnswer questions 41-45. RESEARCH QUESTION: Which pre-procedurаl mouth rinse is more effective in reducing bleeding during NSPT, Chlorhexidine (CHX), hydrogen peroxide, or the plаcebo, salt water (saline solution). HYPOTHESES: A) There is no difference between CHX and hydrogen peroxide. B) There is a difference between CHX and hydrogen peroxide, patients rinsing with CHX will have the least amount of bleeding. METHODOLOGY: In a double-blind study, SCC students between the ages of 18-21 were the subjects (ages = 19, 18, 19, 21,20, 19, 20, 19, 20, 20, 19). Each participant was randomly assigned to the CHX, hydrogen peroxide, or placebo group. The study was conducted over 4 weeks, 1 quad evaluated per week using the O’Leary Bleeding Index. Each participant rinsed with 5mL of their assigned mouth rinse 15 min prior to treatment. RESULTS: A parametric test was used to determine if there was a statistically significant difference between the rinses. The results showed an overall statistically significant reduction in bleeding using CHX (p < 0.03). Additionally, an r-value of - 0.87 demonstrates a measure of correlation between bleeding and use of CHX. 42. What would be the mode from this list of participant ages?a. 18b. 19c. 20d. 21
