Outline of Final Research Achievements

The purpose of this study was to use the newly developed "IANB device" clinically and investigate its efficacy and adverse events. The procedure was judged to be successful if the pain disappeared and an elevation was observed in the sensation threshold on the lower lip. All subjects did not require adjustment of the IANB device.　In all data, a significant elevation in sensation threshold on the lower lip and the disappearance of pain were observed. Three of the five subjects reported having tongue numbness. No notable complications were noted. The appropriate type, concentration, and dosage of local anesthetic must be considered for use in general dental treatment and oral surgical procedures. Our findings suggest the IANB device is useful for eliminating errors between operators, enhancing safety, and improving the success rate when compared to the conventional method.

Academic Significance and Societal Importance of the Research Achievements

研究結果より「IANBデバイス」を使用すれば術者の経験値や患者の解剖学的な個性に影響されることなく安全にほぼ同一の効果の神経ブロックができる可能性がある。神経ブロックが効かないことは術者にとっても患者にとっても恐怖であることから、「IANBデバイス」の普及により、さらにレベルの高い歯科治療時の疼痛管理が可能になると考えられる。ただし、現時点ではCTの撮影が必要であることや設計のプロトコル化、費用、作成に必要な設備の問題もあり、従来の下歯槽神経ブロックを上回るメリットが臨床現場であるのかは議論の余地がある。
