Dental Hygienists' Knowledge, Attitudes, and Comfort Level in Treating Patients with Dental Anxiety.

Fear of dental treatment is a significant problem in the United States, impacting patients as well as oral health care providers. The purpose of this study was to identify the already-acquired knowledge, attitudes, and level of confidence of practicing dental hygienists with respect to the treatment of patients with dental anxiety. A paper survey was developed, pilot tested, and administered at a state-wide annual dental hygiene continuing education (CE) course in North Carolina. The survey domains studied included demographics, practice setting, practice behaviors, dental anxiety awareness, and opinions and attitudes. Item responses included multiple choice, a Likert Scale ranging from "extremely frequent to never" and "strongly agree to strongly disagree," and free response questions. Results were tabulated and descriptive statistics were performed. Of the 157 attendees, 153 met the inclusion criteria (n=153) for a participation rate of 97%. Dental anxiety questionnaires were used "often" or "always" by 20% of the respondents. Less than half (43%) of the respondents stated that they knew the common signs and symptoms of a patient suffering from dental anxiety. However, 92% of the respondents (n=140) indicated confidence in their ability to perceive whether a patient felt stressed. A little more than half (58%) believed their dental hygiene education prepared them for treating patients with mild dental anxiety, 38% with moderate dental anxiety, and 22% with severe dental anxiety. Although the majority of dental hygienists in this study felt confident in their abilities to perceive stress in patients seeking dental care, they were less knowledgeable in recognizing the full range of signs and symptoms of dental anxiety. Questionnaires designed to specifically identify this population were used infrequently. Dental hygiene curricula and continuing education programs should include content on anxiety management for patients exhibiting all levels of dental anxiety.
