Introduction Until recently, dental practice acts in U.S. legal jurisdictions mandated that dental hygiene duties be performed by registered and licensed dental hygienists or dentists. In April 1998, the Kansas state legislature passed House Bill 2724 (HB 2724) revising the dental practice act to allow dental assistants to perform coronal scaling and polishing as part of a routine oral prophylaxis. The Kansas legislature's intent for HB 2724 was to help address access to care and manpower issues in relation to oral health care in the state. The introduction of unlicensed and unregulated assistive personnel as a means for addressing access to oral health care and manpower issues in the dental workforce is unique to the state of Kansas. In contrast, several states have removed practice barriers that previously have prevented licensed and regulated dental hygienists from providing care to underserved populations, thereby addressing many of the access to care and manpower issues. This study is an initial attempt to collect baseline data on HB 2724 through eliciting the perceptions of dental hygienists and scaling assistants in Kansas.
