<教育>歯科麻酔学講座における歯科局所麻酔注射 : シミュレーションモデルを活用した臨床実習の教育効果

In clinical training sessions at the Dental Anesthesia course (5th year dental school), interactive training involving dental local anesthetic injection is conducted. In 1994, training sessions were introduced which demonstrated dental local anesthetic injection employing simulation models. Further, the curriculum was changed to include interactive training sessions following the simulation of these procedures. The educational effectiveness with respect to application of simulation models in terms of local anesthetic injection was investigated. The effectiveness of inferior alveolar nerve conduction anesthesia (foramen mandibulae, direct application method) in the interactive training session was conducted as follows : aponia in the mental nerve domain was evaluated via the application of a vitalometer to the carnassial teeth. Tested teeth were partitioned into successful and failed. Consequently, the anesthetic success rate prior to the simulation model introduction (1993) was 87%. However, the success rate following introduction of the simulation model (1994) was 94% ; further, the increase was significant when compared with results from the previous year. No significant increases in effectiveness occurred from 1994 to 1999, during which continued educational effectiveness was demonstrated. Therefore, the introduction of our local anesthetic injection simulation model in clinical training sessions improved the educational effectiveness
