Background: The present study aimed to investigate changes in intranetwork functional connectivity (FC) and internetwork FC in middle-aged and elderly individuals with normal cognition (NC) and varying degrees of periodontitis to determine the effects of periodontitis on brain function.
Methods: Periodontal findings and resting-state functional magnetic resonance imaging data were acquired from 51 subjects with NC. Independent component analysis and correlation analysis were used for the statistical analysis of the data.
Results: Differences in intranetwork FC were observed among groups in the anterior default-mode network (aDMN), dorsal attention network and dorsal sensorimotor network (dSMN). Compared with the nonperiodontitis (NP) group or the mild-periodontitis group, the analysis of internetwork FC showed increased FC between the auditory network and the ventral attention network (VAN), between the aDMN and the salience network (SN), and between the SN and the VAN and decreased FC between the posterior default-mode network and the right frontoparietal network in the moderate-to-severe periodontitis group. Additionally, internetwork FC between the dSMN and the VAN was also increased in the moderate-to-severe periodontitis group compared to the NP group. The altered intra- and internetwork FC were significantly correlated with the periodontal clinical index.
Conclusion: Our results confirmed that periodontitis was associated with both intra- and internetwork FC changes even in NC. The present study indicates that periodontitis might be a potential risk factor for brain damage and provides a theoretical clue and a new treatment target for the early prevention of Alzheimer disease.
Plain language summary: Recent research has proposed that periodontitis is a potential risk factor for Alzheimer disease (AD). However, the relationship between periodontitis and the brain function of middle-aged and elderly individuals with normal cognition (NC) remains unclear. Analyzing the effect of periodontitis on brain function in the NC stage can provide clues to AD development and help achieve early prevention of dementia. The present study aimed to investigate changes in brain functional connectivity (FC) in NC with different severity of periodontitis to determine the effects of periodontitis on brain function. Both changed intranetwork FC and internetwork FC were found in the moderate-to-severe periodontitis group, and periodontitis was associated with brain network function impairment in NC. The present study indicates that periodontitis might be a potential risk factor for brain damage even in NC stage, and provides a theoretical clue and a new treatment target for the early prevention of AD.
研究背景本研究旨在调查具有正常认知能力（NC）和不同程度牙周炎的中老年人的网络内功能连接（FC）和网络功能连接的变化，以确定牙周炎对大脑功能的影响：方法：研究人员采集了51名NC患者的牙周检查结果和静息态功能磁共振成像数据。独立成分分析和相关分析用于数据的统计分析：结果：在前默认模式网络（aDMN）、背侧注意网络和背侧感觉运动网络（dsmN）中观察到了不同组间网络内FC的差异。与非牙周炎（NP）组或轻度牙周炎组相比，网络FC分析表明，中重度牙周炎组的听觉网络与腹侧注意网络（VAN）之间、aDMN与显著性网络（SN）之间、SN与VAN之间的网络FC增加，而后默认模式网络与右侧额顶网络之间的网络FC减少。此外，与 NP 组相比，中重度牙周炎组中 dSMN 与 VAN 之间的网络 FC 也有所增加。网络内和网络间FC的改变与牙周临床指数显著相关：我们的研究结果证实，即使在 NC 中，牙周炎也与网络内和网络 FC 的变化有关。本研究表明，牙周炎可能是脑损伤的潜在危险因素，为早期预防阿尔茨海默病提供了理论线索和新的治疗靶点：最新研究提出，牙周炎是阿尔茨海默病（AD）的潜在危险因素。然而，牙周炎与认知正常（NC）的中老年人大脑功能之间的关系仍不清楚。分析牙周炎对NC阶段脑功能的影响可以为AD的发展提供线索，有助于实现痴呆症的早期预防。本研究旨在调查不同程度牙周炎的NC患者大脑功能连接（FC）的变化，以确定牙周炎对大脑功能的影响。结果发现，中度至重度牙周炎组的脑内网络功能连接（intranetwork FC）和脑网络功能连接（internetwork FC）均发生了变化，牙周炎与数控系统的脑网络功能损伤有关。本研究表明，即使在NC阶段，牙周炎也可能是脑损伤的潜在危险因素，为早期预防AD提供了理论线索和新的治疗靶点。

Background: To evaluate the effects of artificial intelligence (AI)-assisted dental monitoring (DM) with and without health counseling on the treatment outcomes and oral health-related quality of life (OHRQoL) of patients with periodontitis.
Methods: Patients with periodontitis were randomly assigned to either an AI group (AI group, n = 28), an AI and health counseling group (AIHC group, n = 27), or a control group (n = 27). All patients underwent nonsurgical periodontal treatment. Patients in the AI and AIHC groups underwent additional AI-assisted DM and AI-assisted DM with oral health counseling, respectively, for 6 months. Data on OHRQoL and periodontal measures were collected at baseline and follow-ups.
Results: At 3 months of follow-up, the AI and AIHC groups exhibited a significantly greater reduction in probing pocket depth (mean diff: -0.5 and -0.7) and clinical attachment level (mean diff: -0.5 and -0.6) compared with the control group. At 6 months of follow-up, the AI and AIHC groups exhibited a significantly greater improvement in OHRQoL (mean diff: -4.5 and -4.7) compared with the control group. At 3-month follow-up, the AIHC group exhibited a greater improvement in plaque index (mean diff: -0.2) and OHRQoL (mean diff: -4.3) compared with the AI group.
Conclusion: AI-assisted DM can be used to remind patients with periodontitis of their oral hygiene at home and effectively improve their periodontal measures and long-term OHRQoL.
Plain language summary: Gum disease is a common problem, but new technology could help. In this study, researchers looked at how AI affects gum health and quality of life (QoL). The researchers divided participants into 3 groups. One group used an AI system to monitor their gums at home. Another used AI plus got health advice. The third did not use any special technology. After 3 and 6 months, the AI groups had healthier gums, with less deep pockets and better gum attachment, compared to the group without AI. The group that also got health advice saw even greater improvements, like cleaner teeth and a bigger boost to their QoL. This is exciting because gum disease is tricky to manage alone. The AI system seems to help by reminding people to care for their teeth and gums. With expert guidance, the AI becomes an even more powerful tool for improving long-term oral health and well-being. This study shows how new technologies like AI could transform how we approach common health problems. By providing personalized support, AI can empower people to better manage their own health, leading to better outcomes.

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.

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).

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. The microscope-assisted ARP is associated with a significantly higher chance of removing granulomatous tissue, favorable early healing, and similar crestal bone quality.

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.

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。

After correlation analysis, there were significant correlations between salivary IL-17 and Del-1 and clinical parameters, IL-17 and Del-1 were correlated with PD (r = 0.36, -0.39, p < 0.01), CAL (r = 0.40, -0.42, p < 0.01) and BOP (r = 0.35, -0.37, p < 0.01), they were correlated with FG (r = 0.26, -0.25, p < 0.05) and HbA1c (r = 0.28, -0.40, p < 0.05). Positive relationships were observed between IL-17 and IL-1β and between IL-17 and aMMP-8 (r = 0.80, 0.77, p < 0.01), while Del-1 exhibited negative correlations with IL-1β and aMMP-8 (r = 0.59, 0.69 p < 0.01). Comparison between IL-17 and Del-1 confirmed an inverse relationship (r = -0.71, p < 0.01). Salivary Del-1 levels in the older group were lower compared with young group across the H, P and PDM groups, although these differences were not statistically significant (p > 0.05).</p><p><strong>Conclusions: </strong>Salivary IL-17 and Del-1 levels in the periodontitis with diabetes group showed significant changes compared with the periodontitis group, they exhibited an inverse relationship and were both correlated with periodontal parameters (PD, CAL, and BOP) and diabetic parameters (FG and HbA1c).</p><p><strong>Plain language summary: </strong>Periodontitis and type 2 diabetes mellitus (T2DM) are two common diseases all over the world, some inflammatory mediators (interleukin 17 [IL-17] and developmental endothelial locus-1 [Del-1]) regulate neutrophil p","PeriodicalId":16716,"journal":{"name":"Journal of periodontology","volume":" ","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142289684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
