Abstract：
UNASSIGNED: This study investigated the number of bacterial colonies in four types of suture threads, including silk, nylon, monocryl, and monocryl plus after periodontal surgery in patients with moderate-to-severe periodontitis.
UNASSIGNED: In this single-blind randomized clinical trial, a total of 12 patients with periodontitis who required periodontal flap surgery in all quadrants were included. One type of suture, either silk, nylon, monocryl, or monocryl plus (coated with triclosan), was used following each surgery in each quadrant. Sutures (3 mm) were removed from the mid, posterior, and anterior regions of the flap 7 days postoperatively, and placed in a tube-containing buffer medium to transfer to the culture medium in a laboratory. Then, the bacterial colonies on each culture medium were counted manually. Finally, the mean number of grown colonies (anaerobic and aerobic) was computed and compared in each group of sutures. Data were analyzed by SPSS (Version 20) using the repeated measures ANOVA and least significant difference follow-up tests (α = 0.05).
UNASSIGNED: The findings of this study indicated a significantly higher mean number of aerobic, anaerobic, and aerobic-anaerobic colonies in silk suture than in the other three types of sutures (P < 0.05). However, no significant difference was observed among other types of sutures (P > 0.05).
UNASSIGNED: The results of this study showed that silk suture had a higher bacterial adhesion (aerobic, anaerobic, and aerobic-anaerobic) than monofilament sutures, including nylon, monocryl, and monocryl plus. Moreover, no significant difference was found among the monofilament sutures in the number of colonies grown on them.

摘要：
■这项研究调查了四种类型的缝合线中细菌菌落的数量，包括丝绸,尼龙,monocryl,中度至重度牙周炎患者进行牙周手术后的monocrylplus。
■在这项单盲随机临床试验中，共有12例牙周炎患者需要在所有象限进行牙周皮瓣手术。一种缝合,要么是丝绸，尼龙,monocryl,或monocrylplus（涂有三氯生），在每个象限的每次手术后使用。从中间移除缝线（3毫米），后部,术后7天和皮瓣的前部区域，并置于含有试管的缓冲培养基中以转移到实验室的培养基中。然后，手动计数每种培养基上的细菌菌落。最后,计算并比较每组缝合线中生长的菌落的平均数量（厌氧和有氧）。通过SPSS(版本20)使用重复测量ANOVA和最小显著差异随访测试(α=0.05)分析数据。
■这项研究的结果表明，有氧运动的平均次数明显更高，厌氧,丝线中的好氧-厌氧菌集落高于其他三种类型的缝合线(P<0.05)。然而,其他类型的缝线间无显著差异(P>0.05)。
■这项研究的结果表明，丝线具有较高的细菌粘附性（需氧，厌氧,和好氧-厌氧)比单丝缝合线，包括尼龙,monocryl,和monocrylplus。此外，在单丝缝合线中生长的菌落数量没有发现显着差异。
