本論文では、衝撃を受けた第三大臼歯の外科的抜歯後の下歯槽神経麻痺の発生率について述べた。調査した症例は、外科的に抜歯した1,299歯の789例であった。下歯槽神経麻痺は8例（0.6%），舌神経麻痺は1例（0.08%）であった．下歯槽神経麻痺患者の発生率は、20～29歳で0.4％、30～39歳で0.6％、40歳以上で3.5％であった。この研究では、下歯槽神経麻痺の発生率は、年齢が高い症例や、歯根の分割や周囲の骨の切除が必要な症例に多くみられました。

This paper described the incidence of inferior alveolar nerve paralysis following surgical removal of impacted third molars. The investigated cases were 789 patients with 1,299 teeth that were surgically extracted. Eight (0.6%) patients had the inferior alveolar nerve paralysis and one (0.08%) had lingual nerve paralysis. As for the patients with inferior alveolar nerve paralysis, the incidence was 0.4% in those aged 20 to 29 years, 0.6% in those aged 30 to 39 years, and 3.5% in those aged over 40 years. This study showed that the incidence of inferior alveolar nerve paralysis occurred more frequently in older age cases and in the cases in which the root splitting or the removing the surrounding bone was needed.
