However, the underlying causal and genetic mechanisms remain unclear. Our study employed genome-wide multi-omics approaches to investigate the link between EBV exposure and periodontitis.

背景:牙周炎产生于环境变量和遗传易感性的多方面相互作用,其中微生物感染起着不可或缺的作用。长期以来,人们一直认为EB病毒(Epstein-Barr virus,EBV)暴露与牙周炎活动有关;然而,它们之间的因果关系和遗传联系仍然未知:我们的研究采用孟德尔随机化(Mendelian randomization,MR)方法,包括单变量、多变量、贝叶斯模型平均和反向 MR,在生命过程的背景下研究 EBV 暴露与牙周炎之间的因果关系。此外,还利用连锁不平衡得分回归和共定位分析来评估跨性状遗传相关性,然后利用全转录组关联分析和富集分析来鉴别遗传表型生物特征:结果:EB病毒抗体水平升高,尤其是早期抗原扩散(作为早期感染或再激活的指标),与牙周炎风险增加有关(比值比[OR]:1.27 [1.09-1.47],p = 6.05 × 10-3),并显示出显著的遗传相关性(p = 4.11 × 10-3)。这种发病机制可能涉及位于 17p13.1 的高置信度致病基因 RNASEK。遗传预测的生命早期抗 EBV 免疫球蛋白 G (IgG) 水平与牙周炎风险降低相关(OR:0.89 [0.82-0.97],p = 1.76 × 10-3):本研究强调了EBV暴露及其遗传特征对牙周炎的影响,为EBV相关牙周炎的潜在发病机制和管理策略提供了新的视角。这些发现强调了不同的临床和公共卫生影响,包括抗病毒疗法、病毒疫苗接种策略和个性化牙周炎管理的定制干预措施。我们还需要进一步的研究来验证和扩展我们的发现。白话摘要:牙周炎是一种慢性炎症性疾病,由微生物病原体和宿主免疫系统之间的相互作用驱动。虽然细菌一直是研究的重点,但最近的研究强调了病毒-细菌相互作用的重要性,尤其是 Epstein-Barr 病毒(EBV)--一种感染全球 90% 以上人口的疱疹病毒--在牙周炎发病中的作用。然而,潜在的成因和遗传机制仍不清楚。我们的研究采用了全基因组多组学方法来研究 EBV 暴露与牙周炎之间的联系。我们发现,近期的 EBV 感染或再激活会增加牙周炎的风险,而早年的暴露则可能会降低牙周炎的风险,因为早年的暴露可能会增强免疫抵抗力。基本基因被确定为潜在的介导因素,包括 CRTC3-AS1、HLA-DQA1 和 RNASEK。这些研究结果为了解 EBV 与牙周炎的关系提供了新的视角。例如,病毒检测和控制可使对标准细菌疗法无反应的患者受益,通过接种疫苗及早接触病毒可降低牙周炎的风险。要阐明这些基本机制以及病毒与细菌相互作用的贡献,还需要进一步的临床研究。

BackgroundTo investigate tooth‐related factors that influence pocket closure (PC) and the reduction of pocket probing depths (PPD) after nonsurgical re‐instrumentation (NSRI) as part of step 3 therapy.MethodsA total of 480 patients (10,807 teeth) presenting with residual pockets 6.33 ± 3.79 months after steps 1 and 2 of periodontal therapy were included and retrospectively analyzed before and 5.93 ± 4.31 months after NSRI. Reduction of PPD and PC rates following NSRI were associated with tooth‐related factors, namely tooth type, arch, number of roots, furcation involvement (FI), pulp vitality, mobility, type of restoration, presence of plaque, and bleeding on probing (BOP), using mixed‐effects regression models.ResultsNSRI reduced periodontal pockets persisting after initial cause‐related therapy by (mean ± SD) 1.32 ± 1.79 mm in PPD, and PC rate was 40%. Moderate pockets (4–5 mm) responded better to NSRI than deep pockets (≥ 6 mm) in terms of PC (51% vs. 16%). Both PPD reduction and PC rates of deep residual pockets were significantly influenced by tooth type, arch, number of roots, and presence of BOP.ConclusionTooth type, arch, number of roots, and presence of BOP at re‐evaluation (before NSRI) had a significant and clinically relevant influence on NSRI as part of step 3 therapy. Considering these factors, particularly for deep residual pockets, may allow more tailored re‐intervention.Plain language summaryThe present study aimed to investigate the influence of tooth‐related factors on the outcome of repeated nonsurgical therapy of periodontitis. Therefore, 480 patients (10,807 teeth) presenting with clinical symptoms of persistent periodontitis after initial therapy were administered repeated nonsurgical therapy and retrospectively analyzed. Therapy outcomes were associated with tooth‐related factors, namely tooth type, tooth location (maxilla/mandible), number of roots, involvement of the root furcation area in multi‐rooted teeth, pulp vitality, mobility, restoration, presence of plaque and bleeding upon periodontal probing, using mixed‐effects models. The results revealed that repeated nonsurgical therapy was effective in reducing inflammation and clinical signs of disease, with moderate residual periodontal defects responding better than deep defects. Healing of deep defects after repeated nonsurgical therapy; however, was significantly influenced by the factors: tooth type, location, number of roots, and bleeding on probing. Considering these factors, particularly in deep residual defects which are commonly suggested to be treated surgically, may allow less invasiveness and thus a more tailored re‐intervention.
背景研究作为第三步治疗一部分的非手术再探查术(NSRI)后,影响牙周袋闭合(PC)和牙周袋探查深度(PPD)降低的牙齿相关因素。方法共纳入了480名患者(10,807颗牙齿),他们在牙周治疗第一步和第二步后6.33 ± 3.79个月出现残留牙周袋,并对NSRI前和NSRI后5.93 ± 4.31个月进行了回顾性分析。采用混合效应回归模型,将NSRI后PPD和PC率的降低与牙齿相关因素(即牙齿类型、牙弓、牙根数、毛面受累(FI)、牙髓活力、活动度、修复类型、牙菌斑的存在以及探诊出血(BOP))相关联。结果NSRI将初始病因相关治疗后持续存在的牙周袋的PPD降低了(平均±标度)1.32±1.79 mm,PC率为40%。就PC而言,中度牙周袋(4-5毫米)对NSRI的反应优于深度牙周袋(≥6毫米)(51%对16%)。结论牙齿类型、牙弓、牙根数和重新评估时(NSRI 之前)是否存在 BOP 对作为第三步治疗一部分的 NSRI 有显著的临床相关影响。考虑到这些因素,尤其是对深残留牙周袋的影响,可能会使再次干预更有针对性。本研究旨在探讨与牙齿相关的因素对牙周炎反复非手术治疗结果的影响。因此,对初次治疗后出现顽固性牙周炎临床症状的 480 例患者(10807 颗牙齿)进行了反复非手术治疗并进行了回顾性分析。采用混合效应模型,将治疗结果与牙齿相关因素(即牙齿类型、牙齿位置(上颌/下颌)、牙根数量、多根牙齿的牙根窝沟区受累情况、牙髓活力、活动度、修复情况、牙菌斑存在情况以及牙周探诊出血情况)联系起来。结果显示,反复非手术治疗能有效减轻炎症和疾病的临床症状,中度残留牙周缺损的反应优于深度缺损。然而,反复非手术治疗后深层缺损的愈合受到以下因素的显著影响:牙齿类型、位置、牙根数量和探诊出血。考虑到这些因素,尤其是通常建议手术治疗的深度残留缺损,可以减少创伤,从而进行更有针对性的再干预。

BACKGROUNDGiven the link between chronic inflammation and periodontal pathologies and increased cardiovascular risk, this study aims to investigate if gingivitis exacerbates the inflammatory response and subclinical atherosclerotic markers in women with polycystic ovary syndrome (PCOS).METHODSFor this case-control study, women were assigned to three groups: two PCOS groups (with and without gingivitis) and a control group. Anthropometric and biochemical variables were determined, along with periodontal parameters (probing pocket depth [PPD], clinical attachment level [CAL], bleeding on probing [BOP], plaque index, calculus index, and tooth loss), systemic and neutrophil inflammatory markers (tumor necrosis factor alpha [TNFα], C-reactive protein [CRP], and c-Jun N-terminal kinase [JNK]), systemic oxidative stress mediators (myeloperoxidase [MPO] and glutathione), soluble cellular adhesion molecules, and neutrophil-endothelium cell interactions (rolling flux, velocity, and adhesion).RESULTSOf 104 women recruited, 68 had PCOS, 24 of whom presented gingivitis, and 36 were controls. PCOS patients presented altered sexual hormone, lipid, and carbohydrate profiles. Levels of systemic inflammatory markers, MPO, and soluble platelet selectin (sP-selectin) were higher, and glutathione levels were lower in PCOS patients. BOP, plaque, and calculus index values were higher in PCOS patients with gingivitis. Neutrophils from PCOS patients showed increased JNK and decreased adhesion under flow conditions, with reduced rolling velocity and increased rolling flux and cellular adhesion, all of which were more pronounced in those with gingivitis. BOP was independently associated with rolling velocity, rolling flux, and cellular adhesion.CONCLUSIONNeutrophils of PCOS patients with gingivitis exhibit hyperactivity, promoting interaction with the endothelium and potentially contributing to atherosclerotic disease.PLAIN LANGUAGE SUMMARYCurrently, there is a high prevalence of diseases that affect tooth-supporting tissues (periodontal diseases) and negatively influence the oral health and quality of life of the adult population. These pathologies lead to movement of the teeth and impairment of chewing function, eventually resulting in the loss of teeth. In recent years, the concept of periodontal medicine has arisen and consists of studying how periodontal diseases can influence our general inflammatory system and how systemic inflammatory pathologies can affect our oral health. In the present study, we evaluate a group of women with polycystic ovary syndrome (PCOS), a condition characterized by alterations of sex hormones and lipid profile and weight gain (body mass index). Our results show a high prevalence of gum inflammation among women with PCOS, which affects the interaction of their leukocytes and endothelial cells.

背景鉴于慢性炎症和牙周病变与心血管风险增加之间的联系,本研究旨在调查牙龈炎是否会加剧多囊卵巢综合征(PCOS)女性的炎症反应和亚临床动脉粥样硬化标志物。方法在这项病例对照研究中,女性被分配到三个组:两个 PCOS 组(有牙龈炎和无牙龈炎)和一个对照组。研究人员测定了人体测量和生化变量,以及牙周参数(探诊袋深度 [PPD]、临床附着水平 [CAL]、探诊出血 [BOP]、牙菌斑指数、牙结石指数和牙齿脱落)、全身和中性粒细胞炎症标志物(肿瘤坏死因子α [TNFα]、C反应蛋白 [CRP]、TNFα [TNFα]、TNFα [TNFα])、C反应蛋白 [CRP] 和 c-Jun N 端激酶 [JNK])、全身氧化应激介质(髓过氧化物酶 [MPO] 和谷胱甘肽)、可溶性细胞粘附分子和中性粒细胞-内皮细胞相互作用(滚动通量、速度和粘附)。结果 在招募的 104 名女性中,68 人患有多囊卵巢综合症,其中 24 人患有牙龈炎,36 人为对照组。多囊卵巢综合症患者的性激素、血脂和碳水化合物状况发生了改变。多囊卵巢综合征患者的全身炎症标志物、MPO 和可溶性血小板选择素(sP-selectin)水平较高,谷胱甘肽水平较低。患有牙龈炎的多囊卵巢综合征患者的 BOP、牙菌斑和牙结石指数值较高。多囊卵巢综合征患者的中性粒细胞在流动条件下表现出 JNK 增加和粘附性降低,滚动速度降低,滚动通量和细胞粘附性增加,所有这些在牙龈炎患者中更为明显。结论患有牙龈炎的多囊卵巢综合征患者的中性粒细胞表现出过高的活性,促进了与内皮的相互作用,并可能导致动脉粥样硬化性疾病。这些病变导致牙齿移动和咀嚼功能受损,最终导致牙齿脱落。近年来,牙周医学的概念应运而生,它包括研究牙周疾病如何影响我们的全身炎症系统,以及全身炎症病理如何影响我们的口腔健康。在本研究中,我们对一组患有多囊卵巢综合征(PCOS)的妇女进行了评估,多囊卵巢综合征的特点是性激素和血脂状况的改变以及体重增加(体重指数)。我们的研究结果表明,患有多囊卵巢综合症的妇女牙龈炎症的发病率很高,这影响了她们的白细胞和内皮细胞之间的相互作用。与没有牙龈炎症的多囊卵巢综合症患者或对照组相比,这些妇女的白细胞反应过度,表现出更强的内皮粘附性、更低的流速和更强的滚动性。这项研究为分析牙龈炎患者的中性粒细胞如何表现出高活性,从而促进它们与内皮的相互作用,进而导致动脉粥样硬化疾病的发生提供了新的研究方向。

BACKGROUNDThe use of the operating microscope (OM) for extraction and alveolar ridge augmentation (ARP) is increasing due to enhanced magnification and illumination. The primary objective was to compare the wound healing and crestal bone quality after the use of OM and dental loupes (DL) for ARP.METHODSForty non-molar teeth with periapical lesions in need of extraction and ARP from 33 patients were randomly assigned to 2 groups: DL (control) or OM (test). All procedures were performed by 1 surgeon and assessments done by masked examiners. ARP was performed with an allograft and a resorbable collagen membrane. The presence of granulomatous tissue remnants after debridement was recorded. Cone-beam computed tomography (CBCT) and ultrasound (US) scans were taken during the healing phase up to 16-week visits. Bone cores were retrieved from implant osteotomies for histologic analysis. Patient-reported outcome measurements (PROMs) were assessed.RESULTSAll patients completed all study visits except 1 who dropped out before the last visit. After socket debridement, the test group exhibited significantly fewer sites with tissue remnants (p = 0.01) and a better healing score at 2-week (p = 0.04) and 4-week (p = 0.01) time points. There were no significant differences in 12-week crestal bone healing by histology (p = 0.1), US (p = 0.85), and CBCT healing (p = 0.64) at 12 weeks, as well as PROMs (p > 0.1).CONCLUSIONWithin the limitation of the study, the use of OM for ARP resulted in significantly fewer tissue remnants and favorable early visual wound healing. CBCT and US-derived-crestal bone quality did not show a difference between the 2 groups.PLAIN LANGUAGE SUMMARYAlveolar ridge preservation (ARP) by placing bone particulates in the extraction socket, covered by a wound dressing material, is commonly applied immediately after tooth extraction to reduce jawbone shrinkage in preparation for implant placement later. The jawbone healing varies, depending largely on the ability to remove the etiology, socket features, extent of surgical trauma, and wound stability. Healed jawbone with good quality is favorable for easiness of implant placement and could be related to maintenance of long-term implant health. The surgical microscope with high magnification (up to ∼25×) and co-axial illumination is ideal for assistance in the removal of granulomatous tissue that is believed to interfere with healing, performance of minimally invasive extraction, and stabilization of the wound with meticulous tissue management and fine sutures. This study compared the use of the surgical microscope to dental loupes for ARP in a randomized controlled design.

背景由于放大率和照明度的提高,使用手术显微镜(OM)进行拔牙和牙槽嵴增高术(ARP)的情况越来越多。研究的主要目的是比较使用手术显微镜和牙科放大镜(DL)进行 ARP 后的伤口愈合情况和牙槽嵴骨质量:DL组(对照组)或OM组(试验组)。所有手术均由一名外科医生完成,并由蒙面检查人员进行评估。ARP 采用异体移植和可吸收胶原膜进行。记录清创后肉芽肿组织残留物的存在情况。在愈合期至16周的检查期间,进行锥形束计算机断层扫描(CBCT)和超声波扫描。从种植体截骨处提取骨芯进行组织学分析。结果除一名患者在最后一次就诊前退出外,其余患者均完成了所有就诊。牙槽窝清创后,试验组有组织残留的部位明显较少(p = 0.01),2 周(p = 0.04)和 4 周(p = 0.01)时点的愈合评分较高。在 12 周组织学(p = 0.1)、US(p = 0.85)和 CBCT 愈合(p = 0.64)以及 PROMs(p > 0.1)方面,12 周骨干愈合无明显差异。牙槽嵴保留(ARP)通过在拔牙窝内放置骨颗粒,并用伤口敷料覆盖,通常在拔牙后立即使用,以减少颌骨萎缩,为以后植入种植体做准备。颌骨的愈合情况各不相同,主要取决于去除病因的能力、牙槽的特征、手术创伤的程度以及伤口的稳定性。愈合后的颌骨质量良好,有利于种植体的植入,并能长期保持种植体的健康。手术显微镜具有高倍率(高达∼25×)和同轴照明功能,可帮助清除影响愈合的肉芽肿组织,进行微创拔牙,并通过细致的组织管理和精细缝合来稳定伤口。这项研究在随机对照设计中比较了使用手术显微镜和牙科放大镜进行 ARP 的情况。在显微镜辅助下进行 ARP,肉芽肿组织的清除率明显更高,早期愈合良好,骨嵴骨质相似。肉芽肿组织的清除对即刻种植体植入具有重要意义。这项研究为测试手术显微镜在更具挑战性的口腔内外科手术中促进早期愈合的优势提供了一个模型。

The primary objective was to compare the wound healing and crestal bone quality after the use of OM and dental loupes (DL) for ARP.METHODSForty non-molar teeth with periapical lesions in need of extraction and ARP from 33 patients were randomly assigned to 2 groups: DL (control) or OM (test). All procedures were performed by 1 surgeon and assessments done by masked examiners. ARP was performed with an allograft and a resorbable collagen membrane. The presence of granulomatous tissue remnants after debridement was recorded. Cone-beam computed tomography (CBCT) and ultrasound (US) scans were taken during the healing phase up to 16-week visits. Bone cores were retrieved from implant osteotomies for histologic analysis. Patient-reported outcome measurements (PROMs) were assessed.RESULTSAll patients completed all study visits except 1 who dropped out before the last visit. After socket debridement, the test group exhibited significantly fewer sites with tissue remnants (p = 0.01) and a better healing score at 2-week (p = 0.04) and 4-week (p = 0.01) time points. There were no significant differences in 12-week crestal bone healing by histology (p = 0.1), US (p = 0.85), and CBCT healing (p = 0.64) at 12 weeks, as well as PROMs (p &gt; 0.1).CONCLUSIONWithin the limitation of the study, the use of OM for ARP resulted in significantly fewer tissue remnants and favorable early visual wound healing. CBCT and US-derived-crestal bone quality did not show a difference between the 2 groups.PLAIN LANGUAGE SUMMARYAlveolar ridge preservation (ARP) by placing bone particulates in the extraction socket, covered by a wound dressing material, is commonly applied immediately after tooth extraction to reduce jawbone shrinkage in preparation for implant placement later. The jawbone healing varies, depending largely on the ability to remove the etiology, socket features, extent of surgical trauma, and wound stability. Healed jawbone with good quality is favorable for easiness of implant placement and could be related to maintenance of long-term implant health. The surgical microscope with high magnification (up to ∼25×) and co-axial illumination is ideal for assistance in the removal of granulomatous tissue that is believed to interfere with healing, performance of minimally invasive extraction, and stabilization of the wound with meticulous tissue management and fine sutures. This study compared the use of the surgical microscope to dental loupes for ARP in a randomized controlled design.

Background: The purpose of this randomized, cross-over trial was to determine if a preoperative dose of dexamethasone administered submucosally is as effective as intravenous (IV) dexamethasone in reducing pain, swelling, and analgesic consumption after periodontal flap surgery.

Methods: Thirty-nine patients planned for two similar flap surgeries under IV sedation were included. Before the first surgery, patients were randomized to receive 8 mg of IV or submucosal dexamethasone. Via the alternate route, 0.9% sodium chloride (placebo) was administered. Dexamethasone was administered via the opposite route during the second surgery. A standardized regimen of 600 mg ibuprofen and 325 mg acetaminophen was used to manage postoperative pain. Patients recorded pain and swelling levels on a 21-point numerical rating scale (NRS-21) and a four-point visual rating scale (VRS-4), as well as analgesic usage via a phone application at 12, 24, 48, 72, and 168 h postoperatively.

Results: While NRS-21 and VRS-4 data suggest a trend toward decreased pain and swelling with IV administration, there were no significant differences in analgesic usage or pain at any time and a significant difference in swelling only at 72 h in favor of IV administration (p = 0.047).

Conclusions: There was no significant difference in pain or analgesic usage following periodontal flap surgery comparing IV and submucosal dexamethasone. A statistically significant difference in swelling between groups at 72 h is likely of limited clinical relevance. Submucosal dexamethasone is an effective way to mitigate pain following periodontal surgery, particularly when IV access for sedation is not required.

背景:这项随机交叉试验的目的是确定术前在黏膜下注射地塞米松是否与静脉注射地塞米松一样能有效减轻牙周皮瓣手术后的疼痛、肿胀和镇痛药用量:方法:39 名患者计划在静脉镇静下接受两次类似的翻瓣手术。在第一次手术前,患者被随机分配接受 8 毫克静脉注射或粘膜下地塞米松。通过备用途径,患者接受 0.9% 氯化钠(安慰剂)。第二次手术时,地塞米松通过相反的途径给药。采用 600 毫克布洛芬和 325 毫克对乙酰氨基酚的标准化方案来控制术后疼痛。患者在术后12、24、48、72和168小时分别用21点数字评分量表(NRS-21)和4点视觉评分量表(VRS-4)记录疼痛和肿胀程度,并通过手机应用软件记录镇痛药的使用情况:尽管NRS-21和VRS-4数据表明静脉注射有减轻疼痛和肿胀的趋势,但镇痛剂使用量或疼痛在任何时间都没有显著差异,只有在72小时时肿胀有显著差异,静脉注射更有利(p = 0.047):牙周翻瓣手术后,静脉注射地塞米松和粘膜下地塞米松在疼痛或镇痛剂用量上没有明显差异。72小时后各组间肿胀程度的统计学差异可能对临床意义有限。粘膜下地塞米松是减轻牙周手术后疼痛的有效方法,尤其是在不需要静脉注射镇静剂的情况下。

BackgroundEmerging concerns link periodontitis to an array of cancers, notably thyroid cancer, though investigations into these associations are still in the nascent stages. This population‐based study aimed to investigate the association of thyroid cancer with chronic periodontitis using Taiwan's Longitudinal Health Insurance Database 2010 (LHID2010).MethodsThis case‐control study utilized LHID2010, selecting 2,775 patients diagnosed with thyroid cancer, matched with 8,325 controls based on age, sex, income, and the presence of diabetes, hypertension, hyperlipidemia, human papillomavirus infection, and tobacco use disorder using propensity‐score matching. Multivariate logistic regression models were used to evaluate the association of thyroid cancer with chronic periodontitis.ResultsA chi‐squared analysis demonstrated a significant disparity in the prevalence of chronic periodontitis between those diagnosed with thyroid cancer and the controls, with prevalence rates of 38.5% and 24.1% respectively, and a p‐value less than 0.001. The odds ratio (OR) for having prior chronic periodontitis among patients with thyroid cancer compared to controls was 1.991, with a 95% confidence interval (CI) of 1.816–2.184 and a p‐value less than 0.001. The association was similar between sexes, yielding adjusted ORs of 1.991 (95% CI = 1.816∼2.184) for men and 1.962 (95% CI = 1.765−2.182) for women, indicating a statistically significant higher prevalence of chronic periodontitis in both male and female patients diagnosed with thyroid cancer compared to their control counterparts.ConclusionThe findings highlight chronic periodontitis as a potential risk factor for thyroid cancer, underscoring the importance of integrated health surveillance and preventive strategies that encompass oral health.Plain Language SummaryThis study aimed to explore the link between thyroid cancer and chronic periodontitis. Using Taiwan's Longitudinal Health Insurance Database 2010 (LHID2010), we selected 2,775 patients with thyroid cancer and matched them with 8,325 individuals without the disease based on age, sex, income, and other health conditions such as diabetes, hypertension, high cholesterol, HPV infection, and smoking habits. The study used statistical models to examine the relationship between thyroid cancer and chronic periodontitis. The findings showed that 38.5% of thyroid cancer patients had chronic periodontitis, compared to 24.1% of the control group. The odds of having chronic periodontitis were nearly twice as high in thyroid cancer patients. This pattern was consistent for both men and women. The study underscores the strong connection between chronic periodontitis and thyroid cancer, emphasizing the importance of raising public awareness about the potential risks of periodontitis.
背景人们越来越关注牙周炎与一系列癌症(尤其是甲状腺癌)之间的关系,但对这些关系的调查仍处于初级阶段。方法这项病例对照研究利用台湾纵向健康保险数据库2010(LHID2010),选择了2,775名确诊为甲状腺癌的患者,根据年龄、性别、收入以及是否患有糖尿病、高血压、高脂血症、人类乳头瘤病毒感染和烟草使用障碍等因素,利用倾向分数匹配法与8,325名对照组进行匹配。结果卡方分析表明,甲状腺癌患者和对照组的慢性牙周炎患病率存在显著差异,患病率分别为38.5%和24.1%,P值小于0.001。与对照组相比,甲状腺癌患者患慢性牙周炎的几率比(OR)为1.991,95%置信区间(CI)为1.816-2.184,P值小于0.001。男女之间的相关性相似,男性的调整 OR 值为 1.991(95% CI = 1.816∼2.184),女性为 1.962(95% CI = 1.765-2.182),这表明与对照组患者相比,男性和女性甲状腺癌患者的慢性牙周炎患病率在统计学上都显著较高。本研究旨在探讨甲状腺癌与慢性牙周炎之间的联系。通过台湾纵向健康保险数据库2010(LHID2010),我们选取了2,775名甲状腺癌患者,并根据年龄、性别、收入和其他健康状况(如糖尿病、高血压、高胆固醇、HPV感染和吸烟习惯),将他们与8,325名无甲状腺癌患者进行配对。研究使用统计模型来检验甲状腺癌与慢性牙周炎之间的关系。研究结果显示,38.5%的甲状腺癌患者患有慢性牙周炎,而对照组的这一比例为24.1%。甲状腺癌患者患慢性牙周炎的几率几乎是对照组的两倍。这种模式在男性和女性中都是一致的。这项研究强调了慢性牙周炎与甲状腺癌之间的密切联系,强调了提高公众对牙周炎潜在风险认识的重要性。

BackgroundB‐cell‑specific Moloney MLV insertion site‐1(Bmi‐1)is a crucial osteopenic target molecule. The aim of this study is to explore the effects of Bmi‐1 on alveolar bone resorption and the underlying mechanisms in vitro and vivo.MethodsA <jats:italic>Bmi‐1</jats:italic>‐knockout (<jats:italic>Bmi‐1<jats:sup>−/−</jats:sup></jats:italic>) mouse model was used to investigate the effect of Bmi‐1 on alveolar bone metabolism, with micro‐computed tomography imaging, histology, and immunohistochemistry staining. Furthermore, we utilized a ligature‐induced experimental periodontitis model to examine the impact of <jats:italic>Bmi‐1</jats:italic>‐knockdown (<jats:italic>Bmi‐1</jats:italic><jats:sup>±</jats:sup>) on inflammatory alveolar bone resorption. Finally, we stimulated human periodontal ligament stem cells (hPDLSCs) with lipopolysaccharide (LPS) to explore the potential mechanism of Bmi‐1 overexpression in the process of osteogenesis.ResultsCompared with wild‐type mice, <jats:italic>Bmi‐1</jats:italic><jats:sup>−/−</jats:sup> mice demonstrated more alveolar bone resorption by inhibiting osteogenesis, which was characterized by decreases in Runt‐related transcription factor 2 and type 1 collagen formation. In addition, <jats:italic>Bmi‐1<jats:sup>−/−</jats:sup></jats:italic> mice had lower levels of autophagy markers such as Parkin and LC3, but higher levels of inflammation‐related factors such as interleukin (IL)‐6 and IL‐1β in periodontal tissues. In addition, <jats:italic>Bmi‐1</jats:italic>‐knockdown aggravated ligature‐induced alveolar bone loss. Under in vitro inflammatory conditions, Bmi‐1 overexpression stimulated osteoblast differentiation and inhibited the production of inflammatory factors, as well as the autophagy and apoptosis in hPDLSCs stimulated with LPS. When 3‐methyladenine (3‐MA), an autophagy inhibitor, was added, the osteogenic effect of Bmi‐1 was further enhanced.ConclusionsBmi‐1 alleviates alveolar bone resorption by regulating autophagy, indicating that it could be a potential target for periodontitis prevention and treatment.Plain Language SummaryPeriodontitis is a chronic inflammatory disease, which leads to progressive destruction of periodontal tissues, manifested as periodontal pocket formation, loss of periodontal attachment and alveolar bone resorption. Currently, there is a lack of effective treatments to regenerate damaged periodontal tissues. Therefore, it is of great clinical significance to explore new mechanisms of periodontitis and effective intervention targets. B‐cell‑specific Moloney MLV insertion site‐1 (Bmi‐1) is involved in the regulation of the cell cycle, DNA damage repair, autophagy, bone metabolism, tumor, and other physiopathological processes. Autophagy, as an important mechanism of intracellular self‐regulation, plays an indispensable role in the destruction and repair of periodontal tissues.

背景B细胞特异性莫洛尼MLV插入位点-1(Bmi-1)是一种关键的骨质疏松靶分子。本研究的目的是探讨 Bmi-1 对牙槽骨吸收的影响及其在体外和体内的潜在机制。方法 我们利用 Bmi-1 基因剔除(Bmi-1-/-)小鼠模型,通过微型计算机断层扫描成像、组织学和免疫组化染色,研究 Bmi-1 对牙槽骨代谢的影响。此外,我们还利用结扎诱导的实验性牙周炎模型来研究 Bmi-1 敲除(Bmi-1±)对炎性牙槽骨吸收的影响。最后,我们用脂多糖(LPS)刺激人牙周韧带干细胞(hPDLSCs),探索 Bmi-1 过表达在成骨过程中的潜在机制。结果与野生型小鼠相比,Bmi-1-/-小鼠通过抑制成骨表现出更多的牙槽骨吸收,其特征是 Runt 相关转录因子 2 和 1 型胶原形成减少。此外,Bmi-1-/-小鼠的自噬标记物(如 Parkin 和 LC3)水平较低,但牙周组织中的炎症相关因子(如白细胞介素(IL)-6 和 IL-1β)水平较高。此外,Bmi-1基因敲除会加剧结扎诱导的牙槽骨丧失。在体外炎症条件下,Bmi-1 的过表达刺激了成骨细胞的分化,抑制了炎症因子的产生,并抑制了受 LPS 刺激的 hPDLSCs 的自噬和凋亡。结论Bmi-1通过调节自噬减轻牙槽骨吸收,表明它可能是牙周炎预防和治疗的潜在靶点。目前,还缺乏有效的治疗方法来使受损的牙周组织再生。因此,探索牙周炎的新机制和有效的干预靶点具有重要的临床意义。B细胞特异性莫洛尼MLV插入位点-1(Bmi-1)参与细胞周期、DNA损伤修复、自噬、骨代谢、肿瘤等生理病理过程的调控。自噬作为细胞内自我调节的重要机制,在牙周组织的破坏和修复中发挥着不可或缺的作用。本研究旨在探讨 Bmi-1 对牙周组织的作用及其内在机制。结果发现,Bmi-1能调节自噬作用,保护牙周组织,这表明它可能是预防和治疗牙周炎的潜在靶点。

BackgroundThe aim of this study was to investigate the potential association between vitamin D deficiency and matrix metalloproteinase‐9 (MMP‐9) levels in gingival crevicular fluid (GCF) across various periodontal health and disease statuses.MethodsA total of 200 volunteers were divided into two groups according to serum vitamin D concentration (25(OH)D < 10 ng/mL and 25(OH)D ≥ 10 ng/mL). Periodontal health status was determined based on a full‐mouth periodontal examination and radiographic evaluation. Participants in both groups were categorized according to periodontal diagnoses, encompassing periodontal health, gingivitis, and periodontitis. Following sampling, the MMP‐9 levels in GCF were determined by the enzyme‐linked immunosorbent assay (ELISA) method.ResultsThe GCF MMP‐9 levels were found to be higher in individuals with serum 25(OH)D < 10 ng/mL, in both the healthy and gingivitis and periodontitis groups, compared to those with 25(OH)D ≥ 10 ng/mL. Nevertheless, a statistically significant distinction was observed exclusively within the gingivitis and periodontitis groups. Correlation analysis and robust regression analyses provided additional evidence supporting the predictive role of periodontal disease status and vitamin D concentration in local MMP‐9 levels. These associations remained significant after adjusting for age and sex in robust regression analysis (<jats:italic>p</jats:italic> = 0.002). Furthermore, the inclusion of periodontal clinical parameters in the regression analysis revealed notable associations of clinical attachment loss with local MMP‐9 levels, along with periodontal disease status and serum vitamin D concentration (<jats:italic>p</jats:italic> < 0.001).ConclusionThe findings of our study suggest a potential mechanistic relationship between serum vitamin D levels and periodontitis.PLAIN LANGUAGE SUMMARYVitamin D deficiency is a widespread issue globally due to urban living, less outdoor time, seasonal changes, aging, and sunscreen use, leading to inadequate sun exposure. Low vitamin D levels are linked to several health problems, including hypertension, diabetes, heart diseases, and periodontal diseases, which affect the gums and bones around teeth and can cause tooth loss if untreated. Although the link between vitamin D and periodontal disease is unclear, it may involve the enzyme matrix metalloproteinase‐9 (MMP‐9). Our study examined 200 people, dividing them into two groups based on vitamin D levels. We assessed their gum health and measured MMP‐9 levels in their gingival crevicular fluid, a liquid that seeps out from the tiny space between gums and teeth. We found that people with lower vitamin D levels had higher MMP‐9 levels, especially those with gum disease. Our analysis showed that both vitamin D levels and gum health significantly impact MMP‐9 levels, with gum health being the more influential factor.

背景 本研究旨在探讨维生素D缺乏与不同牙周健康和疾病状态下牙龈缝隙液(GCF)中基质金属蛋白酶-9(MMP-9)水平之间的潜在关联。方法 根据血清维生素D浓度(25(OH)D < 10 ng/mL和25(OH)D ≥ 10 ng/mL)将200名志愿者分为两组。牙周健康状况根据全口牙周检查和放射学评估确定。两组参与者均根据牙周诊断进行分类,包括牙周健康、牙龈炎和牙周炎。采样后,采用酶联免疫吸附试验(ELISA)法测定 GCF 中的 MMP-9 含量。结果发现,在健康组、牙龈炎组和牙周炎组中,与血清 25(OH)D≥10 纳克/毫升的人相比,血清 25(OH)D≥10 纳克/毫升的人的 GCF MMP-9 含量更高。然而,仅在牙龈炎和牙周炎组中观察到了统计学上的显著差异。相关性分析和稳健回归分析提供了更多证据,支持牙周病状态和维生素 D 浓度对当地 MMP-9 水平的预测作用。在稳健回归分析中对年龄和性别进行调整后,这些相关性仍然显著(p = 0.002)。此外,将牙周临床参数纳入回归分析后发现,临床附着丧失与局部 MMP-9 水平以及牙周疾病状态和血清维生素 D 浓度都有显著关联(p < 0.001)。维生素 D 含量低与多种健康问题有关,包括高血压、糖尿病、心脏病和牙周病,牙周病会影响牙齿周围的牙龈和骨骼,如不及时治疗会导致牙齿脱落。虽然维生素 D 与牙周病之间的联系尚不清楚,但可能与基质金属蛋白酶-9(MMP-9)有关。我们的研究调查了 200 人,根据维生素 D 水平将他们分为两组。我们评估了他们的牙龈健康状况,并测量了他们牙龈缝隙液(一种从牙龈和牙齿之间的微小空间渗出的液体)中的MMP-9水平。我们发现,维生素 D 水平较低的人 MMP-9 水平较高,尤其是患有牙龈疾病的人。我们的分析表明,维生素 D 水平和牙龈健康都会对 MMP-9 水平产生重大影响,而牙龈健康是影响更大的因素。保持良好的牙龈健康和充足的维生素 D 水平对管理 MMP-9 至关重要,MMP-9 是一种对愈合和炎症期间组织重塑至关重要的酶。然而,过量的 MMP 可能会迅速破坏牙周组织。

BACKGROUNDBehçet's disease (BD) pathogenesis involves severe outcomes such as blindness, central nervous system manifestations, and deep venous thrombosis that impacts systemic and local inflammatory changes. We tested the hypothesis that BD negatively affects gingival health and increases the severity of gingivitis.METHODSThe study included 37 BD patients with gingivitis without any sign of periodontitis. Systemically healthy 19 patients with gingivitis (G) and 20 periodontally and systemically healthy individuals (C) were recruited as controls. BD patients were further grouped as stable and unstable based on their responses to BD treatment. Clinical periodontal parameters were measured to determine the impact of BD on gingival health. Serum and saliva levels of ELA-2 (neutrophil elastase-2), SLPI (secretory leukocyte protease inhibitor), α1-AT (alpha1-anti-trypsin), VEGF (vascular endothelial growth factor), IL-6 (interleukin-6), IL-8 (interleukin-8), and TNF-α (tumor necrosis factor alpha) were analyzed using multiplex immunoassay to measure the systemic and local inflammatory impact of BD.RESULTSPlaque index (PI), probing pocket depth (PPD), and bleeding on probing (BOP) were significantly higher in the BD group than in the controls (p < 0.05). IL-6 was higher in both serum and saliva in the BD group than in the G group (p < 0.05). ELA-2 levels in saliva were higher in the stable BD group than in the controls, while TNF-α and SLPI were statistically significantly higher in BD than in the control (p < 0.05). Salivary α1-AT level was statistically lower in the BD group compared to the control group.CONCLUSIONOur study suggested that the gingival inflammatory profile was impaired in patients with BD.
背景贝赫切特病(BD)的发病机制包括严重的后果,如失明、中枢神经系统表现和深静脉血栓形成,这些都会影响全身和局部的炎症变化。我们测试了 BD 对牙龈健康产生负面影响并增加牙龈炎严重程度的假设。19 名全身健康的牙龈炎患者(G)和 20 名牙周和全身健康者(C)作为对照。根据对 BD 治疗的反应,将 BD 患者进一步分为稳定型和不稳定型。测量临床牙周参数以确定 BD 对牙龈健康的影响。使用多重免疫测定法分析血清和唾液中 ELA-2(中性粒细胞弹性蛋白酶-2)、SLPI(分泌型白细胞蛋白酶抑制剂)、α1-AT(α1-抗胰蛋白酶)、VEGF(血管内皮生长因子)、IL-6(白细胞介素-6)、IL-8(白细胞介素-8)和 TNF-α(肿瘤坏死因子α)的水平,以衡量 BD 对全身和局部炎症的影响。结果BD组的水泡指数(PI)、探诊袋深度(PPD)和探诊出血量(BOP)明显高于对照组(P < 0.05)。BD 组血清和唾液中的 IL-6 均高于 G 组(P < 0.05)。BD稳定组唾液中的ELA-2水平高于对照组,而BD组的TNF-α和SLPI在统计学上显著高于对照组(P < 0.05)。结论我们的研究表明,BD 患者的牙龈炎症特征受损。
