Yоur grоup is interested in meаsuring the оrаl heаlth of inmates at a local jail and following the population group over time because you theorize that they will develop worsening periodontal health due to lack of preventive care while incarcerated. You are not allowed to bring in sharp metal items like probes or explorers, so you choose an oral hygiene index and bleeding index that do not use them. You choose every 5th person from an alphabetical list of inmates’ names and conduct open mouth exams on these 100 men. Then you have an educational program and give everyone brushes and toothpaste. You will return in 2 weeks and everyone who has improved their oral hygiene and gingivitis by an established amount will be eligible for a prize. You then will return in 6 months and 12 months to evaluate each of these 100 men again to compare their periodontal health to the baseline you established. Use this information to answer questions #48-51 How did you choose your sample group and what type of study is this?
