BACKGROUND/PURPOSE: Free gingival graft (FGG) is used as an effective method to increase the width of keratinized tissue. However, it can cause pain at the donor site. Techniques accompanied by lesser tissue harvesting can reduce pain after surgery. The purpose of this study was to evaluate the self-reported pain perception following harvesting FGG using conventional and accordion methods.
In this randomized clinical trial study, 31 patients with a deficiency of keratinized tissue around implant were investigated. Sixteen subjects in the accordion group and 15 subjects in the control group received conventional FGG. In the accordion group, FGG was harvested with a length of 60% of the mesiodistal length of the recipient area and with the same length as the mesiodistal length of the recipient area in the conventional group. The patients were asked to record their daily pain using a numerical rating scale.
The severity of the pain after reaching to the peak on the second day was reduced and reached zero at day 14 in both groups. Pain severity showed no significant difference between the treatment groups. The highest level of pain was reported in the conventional group in those subjects under 50 years old, and the lowest one was in the conventional group's subjects above 50 years old. There was no difference between men and women in the reported pain between the treatment groups.
Harvesting graft with a smaller size in the accordion group has no effect on reducing pain.

背景/目的：游离龈瓣移植术（FGG）是增加角化组织宽度的一种有效方法。然而，它会导致供区疼痛。减少组织获取量的技术可减轻术后疼痛。本研究的目的是评估采用传统方法和手风琴式方法采集游离龈瓣移植组织后患者自我报告的疼痛感受。
在这项随机临床试验研究中，对31名种植体周围角化组织不足的患者进行了调查。手风琴组16名受试者和对照组15名受试者接受了传统游离龈瓣移植术。在手风琴组中，采集的游离龈瓣移植组织长度为受植区近远中长度的60%，而传统组采集的长度与受植区近远中长度相同。要求患者使用数字评分量表记录每日疼痛情况。
两组在术后第二天疼痛达到峰值后，疼痛严重程度均有所减轻，并在第14天降至零。治疗组之间的疼痛严重程度无显著差异。50岁以下受试者中，传统组报告的疼痛程度最高，50岁以上受试者中，传统组报告的疼痛程度最低。治疗组中，男女报告的疼痛情况无差异。
手风琴组采集较小尺寸的移植组织对减轻疼痛没有效果。
