The purpose of this research intervention is to assess the oral health status and periodontal health of patients with diabetes hospitalized on a general medicine service, and to assess the effect of providing dental prophylaxis and motivational interviewing to patient health-seeking behaviors and provider attitudes towards oral health, as well as on patient health outcomes.

Almost 20% of all patients admitted to the hospital carry a diagnosis of diabetes. Diabetes and periodontal disease have a bi-directional relationship; people with diabetes are at higher risk of tooth loss and poor oral health may impact nutrition and inflammation. Even among those with access to medical treatment for their diabetes, access to dental care may be challenging. In spite of their higher oral health risk, diabetic adults are less likely than their peers to attend a dental visit annually. While oral hygiene measures for ventilator-dependent patients have become standard of care, the oral health of less critically ill hospitalized patients has been noted to decline over the course of their hospitalization and patients generally do not have access to dental treatment., However, invasive dental treatment (restorations, tooth extraction, and periodontal scaling) has been demonstrated to be safe even for critically ill hospitalized patients. The inpatient setting, where patients are already receiving services from multiple disciplines and patients do not need to travel to see a healthcare provider, presents a unique opportunity to make integrative oral healthcare services accessible to diabetic patients, and to increase oral health knowledge of those health professionals caring for patients on an inpatient medical ward.

This study will involve provision of dental prophylaxis ("tooth cleaning") as well as motivational interviewing focused on oral health care-seeking behaviors provided by a dental hygienist to patients with a diagnosis of Type II diabetes who are hospitalized on a medicine floor of Massachusetts General Hospital.
