The purpose of the present study was to compare the influence of primary and secondary closure of the surgical wound on postoperative pain and swelling after removal of impacted mandibular third molars.
A total of 93 patients with bilaterally impacted mandibular third molars were included in the present study. All the patients underwent surgical removal of the bilaterally impacted teeth at the same appointment. Primary closure (group I) was performed on 1 side and secondary closure (group II) was performed on the other side. All the patients were assessed for pain and swelling using the visual analog scale, and the data were collected and analyzed with the paired t test after 7 days.
The swelling in group I was greater than that in group II, with a statistically significant difference (P < .001). The pain was worse in group I than in group II; a difference that also was statistically significant (P < .05). Alveolar osteitis occurred in 4 patients (4.3%) in group I and 3 patients (3.2%) in group II.
Our results have shown that the patients in the secondary closure group had a significantly lesser amount of pain and swelling postoperatively than the primary closure group.
本研究的目的是比较手术创口一期缝合和二期缝合对下颌阻生第三磨牙拔除术后疼痛和肿胀的影响。
本研究共纳入93例双侧下颌阻生第三磨牙患者。所有患者在同一次就诊时接受双侧阻生牙的手术拔除。一侧进行一期缝合（I组），另一侧进行二期缝合（II组）。使用视觉模拟量表对所有患者的疼痛和肿胀情况进行评估，并在7天后收集数据并用配对t检验进行分析。
I组的肿胀程度大于II组，差异有统计学意义（P < .001）。I组的疼痛比II组更严重；差异也有统计学意义（P < .05）。I组有4例患者（4.3%）发生干槽症，II组有3例患者（3.2%）发生干槽症。
我们的结果表明，二期缝合组患者术后的疼痛和肿胀程度明显低于一期缝合组。
