Hygienists and their role in dental practice.

This paper presents the history and introduction of dental hygienists to New Zealand, and illustrates the need for hygienist services with respect to periodontal treatment needs as indicated by the most recent New Zealand epidemiological survey. Examples are given of the way in which dentists may work with hygienists in practice. Hygienists have an economic value and an important role in marketing dentistry. In addition to the benefits of offering a greater range of dental services to patients and avoiding the risk and cost of litigation by patients who previously have been unaware of periodontal problems, the conclusion is made that dental hygienists are very valuable additions to the dental team.
