研究目的:

罗汉果作为一种药食同源的食物,其主要活性成分具有抗炎、抗氧化等多种生物活性。通过本研究,期望采用罗汉果的这些特性,干预慢性牙周炎患者牙种植术后的种植体周围组织的愈合过程,调节炎症反应,抑制微生物感染,从而为慢性牙周炎患者牙种植术后种植体周围组织的愈合提供一种新型天然药物的干预策略及科学参考,并改善患者的愈合水平和生活质量。  

Objectives of Study:

As a medicinal and edible botanical, Siraitia grosvenorii exhibits diverse bioactivities including anti-inflammatory and antioxidant effects. This study aims to leverage these properties to modulate the healing process of peri-implant tissues following dental implant surgery in patients with chronic periodontitis, thereby regulating inflammatory responses, inhibiting microbial colonization, and ultimately providing a novel natural therapeutic intervention strategy with scientific rationale. Such an approach may optimize peri-implant tissue regeneration outcomes while improving the healing level and quality of life of patients.

测量指标:

Outcomes:

指标中文名:

种植体周围龈下菌斑的变化

指标类型:

主要指标

Outcome:

The changes of subgingival plaque around the implant

Type:

Primary indicator

测量时间点:

术后7,14天

测量方法:

通过测序分析术后7,14天种植体周围龈下菌斑的变化。在术后7天和14天分别采集患者的种植体周围龈下菌斑。让患者漱口后,使用无菌刮治器轻轻刮取种植体周围龈下区域的菌斑。将刮取的菌斑迅速转移至无菌EP管中,并立即放入冰盒内保存,以保持样本的活性,防止细菌在常温下发生代谢变化或死亡。采集完成后,在2 - 4小时内将样本转移至实验室进行后续处理。

Measure time point of outcome:

7 and 14 days after the operation

Measure method:

Subgingival plaque samples were collected from peri-implant sites at 7 and 14 days post-surgery using sterile curettes after oral rinsing, immediately stored on ice, and processed within 2-4 hours for sequencing analysis.

指标中文名:

疼痛视觉模拟评分

指标类型:

主要指标

Outcome:

Visual Analogue Scale for Pain

Type:

Primary indicator

测量时间点:

术后1,3,7,14天

测量方法:

通过疼痛视觉模拟评分(visual analogue scale, VAS)评估患者术后1,3,7,14天的疼痛。采用量程 0~10cm 的游标卡尺评估疼痛,患者朝向卡尺无刻度面,医生面向刻度面。卡尺刻度面设 10 个刻度,0分端为无痛,10分端是患者能承受的最痛程度,其间代表不同疼痛级别。记录各组患者术后1,3,7,14天的疼痛程度。

Measure time point of outcome:

1,3,7 and 14 days after the operation

Measure method:

Postoperative pain assessment was conducted using a visual analog scale (VAS) on days 1, 3, 7, and 14 after surgery. Patients viewed the unmarked surface of a 10-cm vernier caliper while investigators referenced the graduated face (0 = pain-free, 10 = maximum tolerable pain) to quantify pain intensity, with scores recorded systematically for each study group.

测量时间点:

术后7,14天

测量方法:

通过ELISA试剂盒评估患者术后7,14天种植体周围龈沟液的炎性因子水平的变化。在提取种植体周围龈沟液前,首先,让患者使用清水漱口,以清除口腔内的食物残渣;使用棉卷隔离唾液,防止其污染龈沟液样本。随后,用电子天平对无菌滤纸条进行精确称重(精确到0.001g),并记录初始重量,将其放入标记好的EP管中。用镊子夹住滤纸条,轻轻插入种植体的颊侧及舌侧近中、中央、远中位点的龈沟内,确保与龈沟底部充分接触,

Gingival crevicular fluid (GCF) was collected from peri-implant sites at 7 and 14 days post-surgery using pre-weighed sterile filter paper strips inserted into six gingival sites (buccal/lingual proximal, mid, and distal) for 30 seconds. After reweighing to calculate GCF volume (assuming 1g/mL density), samples were centrifuged (10,000 rpm, 10 min) to obtain supernatants, which were stored at -80°C and thawed for ELISA analysis of inflammatory factor levels following kit protocols.
