目的:

下顎第三大臼歯の抜歯後の腫脹、疼痛、恍惚感は、最も一般的で予想される術後合併症である。この横断的研究の目的は、下顎第三大臼歯の外科的抜歯後のこれらの術後合併症とBMIの関連性を評価することである。

Objectives: Swelling, pain and trismus after the surgical removal of the mandibular third molars are the most common and expected postoperative complications. The aim of this cross-sectional study was to assess the association of those postoperative complications and BMI after surgical removal of the mandibular third molars.

材料と方法:

本研究では、下顎骨第三大臼歯の抜歯が必要な患者84名を登録し、BMIに応じて4群に分けた。データは一元配置分散分析（Welch's ANOVA）により検定した。グループ内差はGames-Howell検定を用いて検定した。

Material and methods: 84 patients who required the surgical removal of their lower third molar were enrolled in this study and were divided into 4 groups dependent on their BMI. Data were tested by one-way analysis of variance (Welch's ANOVA). The differences were tested by the intragroup using the Games-Howell test.

結果:

BMIの痛みへの影響は、術後24時間以内に統計的に有意な差が認められた。4時間（p=0.014）、6時間（p=0.034、p=0.049）、12時間（p=0.00、p=0.023）、24時間（p=0.010）であった。術後1日目の例外的な腫脹とトリスマスについては、低体重群と標準体重群（p=0.026）、低体重群と過体重群（p=0.014）で統計的に有意な相関はみられなかった。

Results: The effect of BMI on pain had a statistically significant difference within the first 24 postoperative hours: 4 hours (p=0.014), 6 hours (p=0.034, p=0.049), 12 hours (p= 0.00.P=0.023), and 24 hours (p=0.010). For swelling and trismus in the exception on first postoperative day between underweight and normal weight groups (p=0.026), and underweight and overweight groups (p=0.014) no statistically significant correlation was found.

結論:

BMIは患者の術後早期回復に影響を与える。

Conclusion: BMI has an impact on a patient's early postoperative recovery.
