Effects of a Training Needle on Dental Hygiene Student Anxiety.

Purpose: The purpose of this pilot study was to assess whether practicing with a cotton-tipped applicator as compared to a new training device had an effect on the anxiety levels of dental hygiene students prior to administering and receiving their first intraoral injection for local anesthesia.Methods: This pilot study used a convenience sample of senior dental hygiene students from an entry-level Bachelor degree dental hygiene program. Participants completed a pre-test survey after watching a video demonstrating the inferior alveolar nerve block (IANB) injection technique to determine anxiety levels regarding administering and receiving an intraoral injection. Test and control groups were randomly assigned; and participants either received a dental syringe with an attached training needle device (test) or a cotton tip applicator (control). Both groups completed a post-test survey following a 15 minute practice session. Descriptive statistics were performed and Chi-square tests were used to determine significance.Results: Pre-test results showed that 91% of the participants (n=23) reported having anxiety regarding administering or receiving an intraoral injection in one or multiple areas. Chi-square tests determined no statistical significance (p =0.125) between the test and control groups in the post-test surveys.Conclusion: Dental hygiene students demonstrated decreased anxiety levels regarding administering and receiving an intraoral injection regardless of the assigned practice device in this pilot study. While use of a training needle was not shown to be superior at reducing anxiety in novice student operators when compared to a cotton tipped applicator, it may be a useful device for teaching local anesthesia administration techniques.
