The objective of this randomized controlled trial was to compare the effects of different suturing techniques (simple loop suture vs. anchor suture) on the periodontal health of the adjacent second molars after impacted mandibular third molar extraction.
Fifteen patients with bilaterally identical impacted mandibular third molars were used. Using split-mouth design, flaps were closed with either anchor suture technique or simple loop suture technique after the extraction of third molars. Postoperative examination included probing pocket depth (PPD) and clinical attachment level (CAL) measured at the distal surface of the second molars before surgery and 6 months after surgery.
The PPD and CAL in the distal surfaces of the second molars were significantly higher after 6 months in the simple suture group (P = .001), whereas no differences were found in the anchor suture group (P > .05). Intergroup comparisons showed that the 6-month PPD and CAL values of the distal surfaces were significantly higher in the simple suture group compared with the anchor suture group (P = .015).
The results suggest that anchor suture might be a better technique to use to maintain healthy periodontium and to prevent periodontal problems after the extraction of impacted third molars.
本随机对照试验的目的是比较不同缝合技术（简单环扎缝合与锚定缝合）对下颌阻生第三磨牙拔除后相邻第二磨牙牙周健康的影响。
采用15例双侧下颌阻生第三磨牙情况相同的患者。采用分口设计，在第三磨牙拔除后，分别用锚定缝合技术或简单环扎缝合技术关闭创口。术后检查包括术前及术后6个月测量第二磨牙远中面的探诊深度（PPD）和临床附着水平（CAL）。
简单缝合组术后6个月第二磨牙远中面的PPD和CAL显著更高（P = .001），而锚定缝合组未发现差异（P > .05）。组间比较显示，简单缝合组远中面6个月时的PPD和CAL值显著高于锚定缝合组（P = .015）。
结果表明，锚定缝合可能是一种更好的技术，用于在拔除阻生第三磨牙后维持牙周健康并预防牙周问题。
