New Allied Restorative Functions Training in Minnesota: A Case Study

Abstract

Objectives. In 2004, the Minnesota Dental Practice Act was modified to allow dental hygienists and dental assistants to place amalgam, composite, glass ionomer, and stainless steel crowns. A continuing education course was offered to provide required certification for interested dental practitioners. The objectives were: 1) to examine confidence levels of participants and 2) to examine effectiveness of the continuing education program offered.

Methods. A 100-point multiple choice pre-test and post-test exam was used to measure restorative content knowledge. A descriptive survey consisting of 18 items was administered to participants (N=12) in a restorative functions course both prior to (day one) and upon completion of the course (8 days later). Using a 5-point Likert scale, participants indicated their perceived level of confidence in 6 restorative knowledge categories and 9 technical skill categories. Additionally, participants were questioned in their ability to learn these techniques and implement them into private practice.

Results. Exam scores analyzed with a matched pairs t-test found a significant increase in participants' restorative content knowledge (p<.01). Wilcoxen signed rank tests revealed an increase in confidence in all content knowledge categories (p<.01) and technical skill categories (p<.05). Participants did not significantly increase in confidence regarding the ability to implement restorative functions skills into practice (p<.7). Interview data revealed participants remain unclear about ways to incorporate these new duties into the practice schedule.

Conclusion. As anticipated, findings in this case study suggest content knowledge and confidence levels of participants increase following completion of a restorative functions course. Research is needed to identify why participants did not increase in confidence related to implementing restorative skills into their daily schedule. Education regarding concepts of how to incorporate restorative functions by allied professionals into practice may improve participant confidence and implementation.
