第三大臼歯衝突手術後の下顎第二大臼歯の歯周健康に及ぼす新しい縫合法の影響：スプリットマウス無作為化臨床試験

背景:

第三大臼歯の外科的抜歯は、口腔外科領域で最も一般的な手術方法であり、いくつかの合併症と関連している。本研究では、第三大臼歯の外科的抜歯後に新たに提示された縫合法とルーチンの縫合法が術後合併症に及ぼす影響を比較検討することを目的とした。

BACKGROUND: Surgical extraction of the third molar is the most common surgical procedure in the oral surgery field and is associated with several complications. This study aimed to compare the effects of a newly presented suturing technique with the routine suture after surgical removal of the third molar on the postoperative complications.

材料と方法:

この無作為化臨床試験は、口分割二重盲検試験としてデザインされた。20名の患者が本研究に参加した。第三大臼歯の外科的抜去後、新しい縫合法でランダムに片側（症例側）を閉創し、もう片側はルーチンの単純割線縫合で縫合した（対照側）。手術後，痛み，浮腫，トリスマス，ポケットの深さ，第二大臼歯遠位部の付着力喪失を評価した．データは統計的に分析され、両者間で比較された。

MATERIALS AND METHODS: This randomized clinical trial was designed as a split-mouth double-blinded investigation. Twenty patients were involved in the current study. After the surgical removal of the third molar, the new suturing technique was used to close the wound on one side of the patient randomly (case side), and the other side was sutured by the routine simple interrupted stitches (control side). Pain, edema, trismus, pocket depth, and the attachment loss of the distal of the second molar were assessed following the surgery. The data were statistically analyzed and compared between the sides.

結果:

コントロール側の術後の痛みと浮腫は、症例側に比べて有意に少なかった。症例側の第二大臼歯遠位面のポケット深さと歯肉付着力の低下は、対照側に比べて有意に少なかった。また、症例側ではDry socketの症例は認められませんでした。

RESULTS: Pain and edema following the surgery in the control side were significantly less than in the case side. The pocket depth and the gingival attachment loss of the distal aspect of the second molar in the case side were significantly less than in the control side. No case of dry socket was observed in the case side.

結論:

今回発表された縫合法は、創縁を互いに密着させることができ、第三大臼歯打撲除去術後の第二大臼歯の歯周合併症の軽減に役立つと思われる。

CONCLUSION: It seems that the newly presented suturing technique is able to keep the wound margins close to each other and may be helpful in reducing the periodontal complication of the second molar following the surgical removal of the impacted third molars.
