Wing P, Langelier MH, Continelli TA, Battrell A. A dental hygiene professional practice index (DHPPI) and access to oral health status and service use in the US. Journal of Dental Hygiene. 2005;79(2).
This article summarized the findings of a national study that developed a statistical Dental Hygiene Professional Practice Index that defined the professional practice environment of dental hygienists (DHs) in each of the 50 states and the District of Columbia. In addition, it reported the extent to which the index scores were correlated to the number of DHs and dentists, the utilization of dental services, and selected oral health outcomes across the 50 states.
