    Summary

    Enthusiastic drug effect messages significantly reduced patient fear, anxiety, and pain during oral surgery injections. Positive staff attitudes also contributed to placebo effects, enhancing patient experience.

    Area of Science:

    • Oral Surgery
    • Psychology
    • Pain Management

    Background:

    • Placebo effects are well-documented but underutilized in clinical settings.
    • Understanding factors influencing placebo effects can optimize patient care and outcomes.
    • Oral surgery procedures often involve patient anxiety and pain, making them ideal for studying placebo interventions.

    Purpose of the Study:

    • To investigate the influence of communicator status, dental staff attitudes, and drug effect messages on placebo effects in oral surgery.
    • To determine the impact of these variables on pain perception, state anxiety, and fear of injection.
    • To identify key factors that enhance positive placebo responses in dental patients.

    Main Methods:

    • Investigated four variables: communicator status, dentist attitude, dental technician attitude, and drug effect message.
    • Measured dependent variables: pain rating from mandibular-block injection, pre-post placebo state anxiety, and pre-post placebo fear of injection.
    • Utilized an oral surgery clinic setting to assess placebo effects in a real-world clinical environment.

    Main Results:

    • Enthusiastic drug effect messages led to statistically significant reductions in fear of injection and state anxiety.
    • Enthusiastic messages also resulted in markedly lower pain ratings during local anesthetic injection.
    • Positive staff attitudes showed a tendency to enhance placebo effects, with attitude factors achieving statistical significance.

    Conclusions:

    • The message conveying drug effects is a powerful tool for inducing placebo effects in oral surgery.
    • Positive dental staff attitudes play a significant role in modulating patient responses to placebo interventions.
    • Optimizing communication strategies and staff demeanor can improve patient experience and reduce perceived pain and anxiety during dental procedures.
