CASE STUDY #1: Your patient presents for a periodontal maintenance appointment after 10 months.  She is usually on a 4 month recall, but has been dealing with health issues.  She reports hypertension and diabetes, both of which she controls with medications, and her vitals today are BP 130/86, pulse 88, respirations 14 and HbA1C is 9.7.
