@article{oai:hsuh.repo.nii.ac.jp:00009915, author = {KUDO, Masaru and SHINYA, Noboru and KUDO, Masaru and SHINYA, Noboru}, issue = {1}, journal = {北海道医療大学歯学雑誌}, month = {Jun}, note = {P(論文), A new dental training model (M2004IA) for infiltration local anesthetic injection was developed. In this new training model silicon gingival mucosa was designed to expand upon insertion of a needle, his to be followed by introduction of a local anesthetic solution into the silicon gum and silicon gingival mucosa (SGM). This study measured the injection pressure during injection under the SGM. The model M2004IA-HP was designed for hard palate infiltration anesthetic injection training involving the anterior and middle superior alveolar (AMSA) branch of the maxillary nerve. The SGM surrounding the glass filter and the urethane resin jaw (URJ) are held together with glue to maintain space that will permit expansion. The injection pressure for the M 2004IA was 241.3±32.1 (mean±SD) mmHg at the end of a 0.5 ml injection. The lower jaw of the M2004IA (M2004IA-LMBG) was designed for infiltration anesthetic injection training involving the first molar buccal gingiva. The injection pressure for delivery of 0.5ml of solution over approximately 90 seconds was 357.2 ±15.0 mmHg at the end of the injection. The pressure following the start of injection with the M2004IA-LMBG was 5.3± 2.3 mmHg one second after the start of injection, and 109.2±12.0 mmHg at 10 seconds. These values approximated the actual injection pressures from previously reported (Kudo et al., 2004). Infiltration anesthetic injections ; therefore, this novel device, the M2004IA, is effective to generate injection pressures similar to those actually experienced by human volunteers. The model is also suitable for low-pressure injection training. Training in pain-free local anesthetic injection, e. g., lowpressure injection, is essential to promote safe dental treatment under local anesthesia. The newly developed M2004IA enables the simulation of authentic infiltration anesthetic injection conditions. An intensive effort to provide safe training, and also with respect to continuing pre-clinical training in infiltration anesthetic injection with the introduction of the M2004IA can be anticipated.}, pages = {25--30}, title = {Development of a novel training model for dental infiltration anesthetic injections}, volume = {24}, year = {2005} }
