The oral health care system remains largely siloed from the broader health care system and traditionally has been underused by primary care delivery systems as a pathway to oral health promotion, prevention, and early intervention. Challenges persist that hinder the understanding and provision of oral health care in primary care. A key strategy for improving access to health care and health outcomes is integrating oral health and medical care; however, limited research has been published to guide the professions in assembling an efficient and effective integrated medical-dental health system.
