This study compared the results of two types of access flap used in removing impacted mandibular third molars. Fifteen patients were given periodontal examinations consisting of measurements of attachment level, level of the gingival margin, and width of the masticatory mucosa at three locations around the mandibular second molars. The examinations were done preoperatively, and two, six, and 12 weeks after removal of the impacted molars. Analyses of variance indicated that there was no significant difference between the two flap techniques and, therefore, the choice of flap technique is one of operator preference. There was a significant decrease in mean sulcus depth at all measured points for either flap technique, indicating a generally healthier condition around mandibular second molars 12 weeks after the surgical removal of mandibular third molars.
本研究比较了用于拔除下颌阻生第三磨牙的两种入路瓣的效果。对15名患者进行了牙周检查，包括在下颌第二磨牙周围三个位置测量附着水平、牙龈边缘水平和咀嚼黏膜宽度。检查在术前以及拔除阻生磨牙后的2周、6周和12周进行。方差分析表明，两种瓣技术之间没有显著差异，因此，瓣技术的选择取决于术者的偏好。两种瓣技术在所有测量点的平均龈沟深度均显著降低，表明下颌第三磨牙手术拔除12周后，下颌第二磨牙周围的状况总体上更健康。
