Behavioral Video to Navigate Predoctoral Dental Students Toward Safer Practice.

OBJECTIVES
Local anesthesia is considered essential knowledge within the dental profession as it helps to address pain management. Operator percutaneous needlestick injuries associated with delivery of dental anesthesia is common for dental healthcare providers. Study proposes a supplemental technique to reduce self-inducing novice operator needlestick injury to complement existing pedagogies for the preclinical local anesthesia curriculum. The purpose of study is to evaluate whether a local anesthesia behavioral video can navigate students to safer clinical practice. Further, a supplemental technique is proposed in whether assessing instrument retraction technique in clinical patient care leads to decreased self-inducing intraoral needle stick injury for novice predoctoral dental operator.


METHODS
Beginning in 2011, predoctoral dental students were asked to view a "what not to do" video within a summative assessment and identify at least five behaviors that were unacceptable errors for delivering local anesthesia. Operator intraoral needlestick injury was also tracked per the bloodborne exposure reports within predoctoral patient clinics.


RESULTS
Data from the learners' response identified progression in recognizing unacceptable errors from behavioral video. Intraoral needlestick injury, eight and nine years prior and after introduction of video showed significance with low correlation coefficient.


CONCLUSIONS
More data needs to be gathered and evaluated in other dental school settings to determine if this supplemental educational video decreases needlestick injury in novice operators. Results suggest this behavioral video may guide novice operators to overall safer clinical practice.
