The PREMIERS study is a proposal for conducting an adequately powered two center phase III randomized controlled trial to test whether intensive periodontal treatment reduces the risk of recurrent vascular events among ischemic stroke and TIA survivors. The study uses the resources in both states including established dental centers, Joint Commission Certified Stroke Centers, the Schools of Public Health, and the Institute for Partnerships to Eliminate Health Disparities. The proposal addresses specific issues with regards to recruitment of African-American and rural stroke/TIA patients advocating the use of culturally appropriate strategies to educate the study subjects regarding stroke, periodontal disease and the periodontal stroke link.
The study proposes to utilize economic evaluation of the periodontal intervention from the budgetary perspective. The focus will be on the financial sustainability of providing aggressive periodontal therapy (with certain, although relatively low expenditures) in exchange for a reduction of uncertain recurrent vascular events that may require high cost emergency department utilization and/or inpatient care. The sustainability of the proposed intervention after the completion of the project is integrally linked to the health economic assessment to show the health care cost savings. By integration with a rural primary care center, with an African American majority and households with average incomes below the state average, the study ensures that the proposed intervention to reduce stroke disparity is applicable to this target population.

Active Comparator: Intensive Dental Treatment
Patients will undergo up to five sessions of full-mouth removal of subgingival dental plaque by the use of scaling and root planning under local anesthesia. Any hopeless teeth will be extracted during this treatment period, which will be as short as possible, but will extend to no more than 4 weeks. In addition to standard scaling and root planning, the investigators seek to better suppress the oral biofilm by administering Arestin locally into the periodontal pockets ≥6 mm. All patients will be reexamined at 3, 6 and 9 months for safety checks. Patients will be given instructions in basic oral hygiene and treated for stroke risk factors in accordance to the current guidelines for secondary stroke prevention.

Patients will undergo supragingival mechanical scaling and polishing. They will be informed of the presence and severity of their periodontal disease and will be advised to be seen by their dentist if their condition requires immediate attention. If they have no dental provider they will be referred for care. All patients will be reexamined at 3, 6 and 9 months for safety checks. Among the group the periodontal condition will be monitored to assure there is no progression of disease. If any site demonstrates an increase in periodontal pockets >3mm, they will receive site-directed scaling and root planing. Patients will be given instructions in basic oral hygiene and treated for stroke risk factors in accordance to the current guidelines for secondary stroke prevention. At the completion of the study, the control treatment patients will be offered to receive the same dental care as provided to the intensive treatment group as needed.
