INTRODUCTION Oral health care access for vulnerable populations is an important public health issue in America and is becoming a priority for discussion among policy makers, health care educational institutions, providers, and a segment of the public at large. Improving overall health outcomes requires a collaborative effort and innovative approaches that address education, delivery, and financing of oral health care. The purpose of this study was to investigate Massachusetts' key informants' knowledge and experience regarding development and implementation of medical/dental integration practices, including recognized barriers and possible solutions for integration enhancement.
