Background
Excess weight (EW), especially in women of childbearing age, those who are pregnant, as well as postpartum, is a problem worldwide. Fat accumulation deregulates the inflammatory response, contributing to the development of health problems, such as periodontitis. This study investigated the association between EW and periodontitis during pregnancy.
Methods
A cross-sectional, multicenter study involved 1745 postpartum women in Brazil. Socioeconomic-demographic data, gestational history, lifestyle behavior, and general and oral health conditions were obtained. Pre-pregnancy body mass index (BMI) was collected from medical records with EW being the exposure. Both tooth loss and clinical attachment level (CAL) were evaluated, and the presence of periodontitis was the outcome. Logistic regression, odds ratio (OR) and 95% confidence interval (95% CI), and quantile regression, beta coefficient and 95% CI, estimated the association between EW (BMI) and periodontitis and its combined effect with tooth loss ≥3, as dichotomous and continuous variables (CAL and tooth loss), with 5% significance level.
Results
The EW was 27.7% prevalent and periodontitis was 11.7%. There was a positive association between EW and periodontitis: ORadjusted:1.39; 95% CI:1.01;1.92 and between EW and periodontitis combined with tooth loss ≥3: ORadjusted:1.73; 95% CI:1.36;2.20. The adjusted association between EW and periodontitis as continuous variables was also positive, showing that for each unit of increased BMI, there was an elevation in the mean CAL (p = 0.04) and tooth loss (p < 0.01), with statistical significance.
Conclusions
There was a moderate association between EW and periodontitis during pregnancy, with an even greater association of pregnant women with EW presenting periodontitis combined with tooth loss.
背景：体重超标（EW），尤其是育龄妇女、孕妇和产后妇女的体重超标，是一个全球性问题。脂肪堆积会降低炎症反应，导致牙周炎等健康问题的发生。本研究调查了孕期 EW 与牙周炎之间的关系：这项横断面多中心研究涉及巴西的 1745 名产后妇女。获得了社会经济-人口学数据、妊娠史、生活方式、一般健康状况和口腔健康状况。从医疗记录中收集了孕前体重指数（BMI），并将 EW 作为暴露指标。对牙齿脱落和临床附着水平（CAL）进行评估，并以是否存在牙周炎作为结果。通过逻辑回归、几率比（OR）和 95% 置信区间（95% CI），以及量回归、贝塔系数和 95% CI，估算了 EW（BMI）与牙周炎之间的关系，以及其与牙齿脱落≥3（二分变量和连续变量（CAL 和牙齿脱落））之间的综合影响，显著性水平为 5%：结果：EW患病率为27.7%，牙周炎患病率为11.7%。EW与牙周炎呈正相关：EW与牙周炎之间存在正相关：OR调整值为1.39；95% CI：1.01；1.92；EW与牙周炎合并牙齿缺失≥3之间存在正相关：OR调整值为1.73；95% CI：1.36；2.20。作为连续变量，EW 与牙周炎之间的调整关联也是正相关的，表明体重指数每增加一个单位，平均 CAL（P = 0.04）和牙齿脱落（P 结论：EW 与牙周炎之间的关系是中度相关的：妊娠期 EW 与牙周炎之间存在中度关联，EW 孕妇合并牙周炎和牙齿脱落的关联更大。

Background: Although several studies have demonstrated a bidirectional relationship between nonalcoholic fatty liver disease (NAFLD) and chronic periodontitis, few studies have reported that NAFLD causes chronic periodontitis, especially in the Asian population.
Methods: This study was conducted on 129,087 individuals, and the NAFLD score was assessed using the Fatty Liver Index (FLI), Hepatic Steatosis Index (HSI), and Framingham Steatosis Index (FSI). The incidence of chronic periodontitis was defined as a diagnostic code with dental procedures. Multi-variable adjusted Cox proportional hazard regression analysis was performed with hazard ratio (HR) and 95% confidence intervals (CIs).
Results: Nine thousand one hundred and twenty-eight chronic periodontitis cases (7.1%) were identified during a mean 7.4 years follow-up period. Each NAFLD score was related to chronic periodontitis. In the FLI score, HR and 95% CIs for the incidence of chronic periodontitis compared with a low FLI group were as follows: indeterminate FLI: 1.19 (1.12-1.26), high FLI: 1.32 (1.18-1.47). In the HSI and FSI scores, HR and 95% CIs for the incidence of chronic periodontitis were 1.13 (1.05-1.22) and 1.23 (1.05-1.31), respectively.
Conclusions: All NAFLD scores were associated with chronic periodontitis in the Korean population. As chronic periodontitis can aggravate the liver status, patients with NAFLD may need regular dental visits.

Background
The aryl hydrocarbon receptor (AhR) has been studied as an intracellular pattern recognition receptor that can identify bacterial pigments. To identify a potential therapeutic target for periodontitis, we investigated the expression of AhR in periodontitis and its role in the pathogenesis of periodontitis.
Methods
First, we analyzed AhR expression in a single-cell dataset from human periodontal tissue. Quantitative polymerase chain reaction (qPCR), immunofluorescence, and immunohistochemistry were used to verify the AhR level. Later, we determined the phenotypes of ligature-induced periodontitis in myeloid-specific AhR-deficient mice (Lyz2-Cre+/− AhRfx/fx), after which RNA sequencing (RNA-seq), qPCR, Western blot, immunofluorescence, and immunohistochemistry were used to investigate the impacts of AhR on periodontitis and its mechanism. Finally, we determined the therapeutic effect of AhR agonist 6-Formylindolo[3,2-b]carbazole (FICZ) administration on murine periodontitis and verified the effects of FICZ on macrophage polarization in vitro.
Results
AhR expression was enhanced in macrophages from periodontitis patients. Deletion of AhR from macrophages aggravated ligature-induced periodontitis and promoted the inflammatory response. Calcium/calmodulin-stimulated protein kinase II (CaMKII) phosphorylation was accelerated in AhR-deficient macrophages. Inhibiting CaMKII phosphorylation ameliorated periodontitis in Lyz2-Cre+/− AhRfx/fx mice. FICZ treatment blocked alveolar bone loss and relieved periodontal inflammation. FICZ diminished M1 macrophage polarization and promoted M2 macrophage polarization upon M1 macrophage induction.
Conclusion
AhR played a protective role in the pathogenesis of periodontitis by orchestrating macrophage polarization via interacting with the CaMKII signaling pathway.

Background
Acute kidney injury (AKI) is characterized by rapid renal decline. Periodontitis, a chronic oral inflammatory disease, is increasingly associated with renal dysfunction. Although periodontitis is recognized as a contributor to kidney damage, the mechanisms linking it to AKI remain unclear.
Methods
This study explored the effects of Porphyromonas gingivalis (P. gingivalis) W83-infected periodontitis on AKI in C57BL/6J mice, using ischemia-reperfusion injury 55 days post-infection. Gingipain inhibitors, KYT-1 and KYT-36, were applied. Detection of P. gingivalis was performed using quantitative real-time polymerase chain reaction (qRT-PCR) and PCR, while transcriptome sequencing, qRT-PCR, immunohistochemistry, and immunofluorescence staining assessed renal damage. In vitro, HK-2 cells were exposed to P. gingivalis at a multiplicity of infection of 10 for 48 h, with inhibition by gingipain or oncostatin M (OSM). Disruption of tight junctions (TJs) was quantified using qRT-PCR, transepithelial electrical resistance, and cell counting kit-8 assays.
Results
Periodontitis worsened AKI, linked to P. gingivalis infection and renal TJ disruption in the kidney. P. gingivalis infection activated OSM expression, which correlated positively with gingipain. Significantly, OSM and gingipain might collaboratively contribute to the damage of renal TJs, with the reduced expression of TJ proteins. Suppressing gingipain activity presented itself as a protective strategy against the destruction of TJs and the attendant worsening of AKI due to periodontitis.
Conclusions
Our study enhances the understanding of the interplay between periodontitis and AKI, highlighting the harmful impact of P. gingivalis in AKI.
背景：急性肾损伤（AKI）的特点是肾功能急剧下降。牙周炎是一种慢性口腔炎症性疾病，越来越多地与肾功能障碍相关。尽管牙周炎被认为是造成肾损伤的一个因素，但它与急性肾损伤的关联机制仍不清楚：本研究探讨了牙龈卟啉单胞菌（P. gingivalis）W83感染的牙周炎对C57BL/6J小鼠AKI的影响。应用牙龈蛋白酶抑制剂 KYT-1 和 KYT-36。使用定量实时聚合酶链式反应（qRT-PCR）和 PCR 检测牙龈脓疱病，同时使用转录组测序、qRT-PCR、免疫组织化学和免疫荧光染色评估肾损伤。在体外，HK-2细胞以10的感染倍数暴露于牙龈脓疱疮菌48小时，并受到gingipain或oncostatin M（OSM）的抑制。使用 qRT-PCR、跨上皮电阻和细胞计数试剂盒-8 检测法量化紧密连接（TJ）的破坏情况：结果：牙周炎加重了 AKI，这与牙龈脓胞感染和肾脏 TJ 破坏有关。牙龈脓疱疮感染激活了 OSM 的表达，而 OSM 的表达与 gingipain 呈正相关。值得注意的是，OSM和gingipain可能会共同导致肾脏TJ受损，同时降低TJ蛋白的表达。抑制gingipain的活性可作为一种保护性策略，防止TJ被破坏以及随之而来的牙周炎导致的AKI恶化：我们的研究加深了人们对牙周炎与 AKI 之间相互作用的理解，突出了牙龈脓疱病在 AKI 中的有害影响。

Background
Periodontal diseases are associated with dysbiosis in the oral microbial communities. Managing oral biofilms is therefore key for preventing these diseases. Management protocols often include over-the-counter antimicrobial mouth rinses, which lack data on their effects on the oral microbiome's ecology, bacterial composition, metabolic activity, and dysbiosis resilience. This study examined the efficacy of antimicrobial mouth rinses to halt dysbiosis in in vitro oral biofilms under periodontitis-simulating conditions.
Methods
Multispecies oral biofilms were grown on hydroxyapatite discs (HADs) and rinsed daily with one of six mouth rinses. Positive and negative controls were included. After three rinses, biofilms were analyzed with viability quantitative polymerase chain reaction and visualized using scanning electron microscopy. Supernatants of rinsed biofilms were used for metabolic activity analysis. In addition, human oral keratinocytes were exposed to rinsed biofilms to assess their inflammatory response. All outputs were analyzed for correlation using Spearman coefficient.
Results
Product-related changes were observed in the rinsed biofilms. Three of the six tested mouth rinses could significantly prevent dysbiosis with ≥30% reduction in pathobiont abundance relative to the control. These biofilms had lower metabolic activity, and the exposed human oral keratinocyte produced less interleukin-8. Interleukin-8 production correlated to both pathobiont quantity and the metabolic activity of the biofilms.
Conclusion
Some mouth rinses could support biofilm resilience and stop dysbiosis evolution in the biofilm model, with a clear product-related effect. Such mouth rinses can be considered for patients under maintenance/supportive periodontal therapy to prevent/delay disease recurrence. Others are more useful for different periodontal therapy stages.

BackgroundRecent studies suggest a role for microscopic crystalline particles of residual dental calculus in the pathogenesis of periodontitis. The purpose of this ex vivo study was to compare the effectiveness of scaling and root planing (SRP) alone versus SRP combined with 24% ethylenediamine‐tetra acetic acid (EDTA) gel in removing calculus from extracted teeth and to determine the optimal length of time for application of the EDTA.MethodsSpecimens consisted of 32 extracted teeth with heavy root calculus. A 4‐mm diameter site was prepared on the root surface of each tooth which then underwent SRP. EDTA was applied to four timed groups: 30 s; 60 s; 120 s; and 180 s. Photomicrographs were taken at 40× magnification using white light (WL) and laser fluorescence (LF). Photomicrographs were analyzed using ImageJ. Specimens were also evaluated with scanning electron microscopy (SEM).ResultsThe mean area of residual calculus after SRP was 45%–53% (45.6% ± 19.6% WL, 53.8% ± 19.7% LF). Burnishing with EDTA for one minute following SRP reduced calculus to only 14%–18% (13.9% ± 12.5% LF, 18.2% ± 11.1% WL). Use of EDTA for greater than 1 min showed no further calculus removal. SEM revealed the surface of remaining calculus was altered by burnishing with EDTA.ConclusionSRP alone or SRP + 24% EDTA gel failed to remove all calculus. SRP alone removed >60% of calculus from root surfaces. Adjunctive use of 24% EDTA gel burnished on the root surface removed most of the calculus residual after SRP. Calculus remaining after EDTA burnishing exhibited a significantly altered morphologic appearance.

The purpose of this ex vivo study was to compare the effectiveness of scaling and root planing (SRP) alone versus SRP combined with 24% ethylenediamine‐tetra acetic acid (EDTA) gel in removing calculus from extracted teeth and to determine the optimal length of time for application of the EDTA.MethodsSpecimens consisted of 32 extracted teeth with heavy root calculus. A 4‐mm diameter site was prepared on the root surface of each tooth which then underwent SRP. EDTA was applied to four timed groups: 30 s; 60 s; 120 s; and 180 s. Photomicrographs were taken at 40× magnification using white light (WL) and laser fluorescence (LF). Photomicrographs were analyzed using ImageJ. Specimens were also evaluated with scanning electron microscopy (SEM).ResultsThe mean area of residual calculus after SRP was 45%–53% (45.6% ± 19.6% WL, 53.8% ± 19.7% LF). Burnishing with EDTA for one minute following SRP reduced calculus to only 14%–18% (13.9% ± 12.5% LF, 18.2% ± 11.1% WL). Use of EDTA for greater than 1 min showed no further calculus removal. SEM revealed the surface of remaining calculus was altered by burnishing with EDTA.ConclusionSRP alone or SRP + 24% EDTA gel failed to remove all calculus. SRP alone removed >60% of calculus from root surfaces. Adjunctive use of 24% EDTA gel burnished on the root surface removed most of the calculus residual after SRP. Calculus remaining after EDTA burnishing exhibited a significantly altered morphologic appearance.","PeriodicalId":16716,"journal":{"name":"Journal of periodontology","volume":"118 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2024-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141463118","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}
BackgroundDiabetes is one of the major inflammatory comorbidities of periodontitis via 2‐way interactions. Cystathionine γ‐lyase (CTH) is a pivotal endogenous enzyme synthesizing hydrogen sulfide (H2S), and CTH/H2S is crucially implicated in modulating inflammation in various diseases. This study aimed to explore the potential role of CTH in experimental periodontitis under a hyperglycemic condition.MethodsCTH‐silenced and normal human periodontal ligament cells (hPDLCs) were cultured in a high glucose and Porphyromonas gingivalis lipopolysaccharide (P.g‐LPS) condition. The effects of CTH on hPDLCs were assessed by Cell Counting Kit 8 (CCK8), real‐time quantitative polymerase chain reaction (RT‐qPCR), and enzyme‐linked immunosorbent assay (ELISA). The model of experimental periodontitis under hyperglycemia was established on both Cth−/− and wild‐type (WT) mice, and the extent of periodontal destruction was assessed by micro‐CT, histology, RNA‐Seq, Western blot, tartrate‐resistant acid phosphatase (TRAP) staining and immunostaining.ResultsCTH mRNA expression increased in hPDLCs in response to increasing concentration of P.g‐LPS stimulation in a high glucose medium. With reference to WT mice, Cth−/− mice with experimental periodontitis under hyperglycemia exhibited reduced bone loss, decreased leukocyte infiltration and hindered osteoclast formation, along with reduced expression of proinflammatory cytokines interleukin‐6 (IL‐6) and tumor necrosis factor alpha (TNF‐α) in periodontal tissue. RNA‐seq‐enriched altered NF‐κB pathway signaling in healthy murine gingiva with experimental periodontitis mice under hyperglycemia. Accordingly, phosphorylation of p65 (P‐p65) was alleviated in CTH‐silenced hPDLCs, leading to decreased expression of IL6 and TNF. CTH knockdown inhibited activation of nuclear factor kappa‐B (NF‐κB) pathway and decreased production of proinflammatory cytokines under high glucose and P.g‐LPS treatment.ConclusionThe present findings suggest the potential of CTH as a therapeutic target for tackling periodontitis in diabetic patients.

Background
This randomized controlled trial with two parallel arms and a 1:1 allocation ratio aimed to compare early microvascular healing (primary outcome), surgical times, and patient-reported outcomes (PROM) after harvesting palatal epithelialized gingival grafts (EGG), where hemostasis was achieved with sutures and hemostatic sponges (control) or with a sutureless approach (test).
Methods
From a total of 33 patients, 34 EGG were harvested. Thirty-two were randomized to the test/control group (n = 16) and two were excluded. Early palatal microvascular healing was assessed at 7, 14, and 30 days with laser speckle contrast imaging (LSCI). Postoperative bleeding, pain, discomfort, and analgesic consumption were assessed over 2 weeks with a dedicated questionnaire.
Results
A faster onset and resolution of postharvest hyperemia was observed in the test group where peak blood flow was reached at 7 days. No significant blood flow differences were observed between the groups at any of the evaluated timepoints. The mean surgical time was 13 min shorter in the test (p = 0.00). No significant differences were observed for postoperative bleeding and analgesic consumption at any timepoint.
Conclusions
The tested approach represents a viable alternative to the standard one, providing no relevant differences in microvascular, clinical, and patient-related results, but with significantly shorter surgical times.

Background
The composite outcome measure (COM) more comprehensively assesses the clinical efficacy of regenerative surgery than a single probing measurement. We aimed to assess long-term success defined by the COM (clinical attachment level [CAL] gain of ≥3 mm and postsurgery probing pocket depth [PPD] ≤ 4 mm) and influencing factors of regenerative surgery using bone substitutes and resorbable collagen membrane (RM) for intra-bony defects (IBDs).
Methods
We retrospectively collected data from patients who underwent regenerative surgery using deproteinized bovine bone mineral (DBBM) and RM for IBDs. CAL and PPD values were compared at baseline (preoperative), 1 year (short-term), and at the last follow-up (5–10 years). Multivariate logistic regressions were performed to identify factors influencing COM-based long-term success.
Results
Eighty-one defects in 75 teeth of 33 patients who completed follow-up (6.5 ± 1.4 years) were included. One tooth was lost. All defects with complete follow-up exhibited long-term average CAL gain (3.00 ± 2.00 mm, 95% confidence interval [CI]: 2.56–3.44 mm, p < 0.001) and PPD reduction (2.06 ± 1.91 mm, 95% CI: 1.64–2.49 mm, p < 0.001). Long-term success was achieved in 38.8% of IBDs. CAL and PPD values were comparable between 1 year and the last follow-up. Logistic regression analyses revealed that male sex (odds ratio [OR] = 0.23, 95% CI: 0.07–0.75) and bleeding on probing (BOP) during supportive periodontal therapy (OR = 0.96, 95% CI: 0.94–0.99) were risk factors for long-term success.
Conclusions
Regenerative surgery with DBBM and RM for IBDs can achieve some degree of long-term success defined by COM. However, within this study's limitations, male sex and higher BOP incidence postoperatively are negatively associated with optimal long-term success.

Background
The aim of this study was to evaluate the incidence of preloading crestal bone loss (PLCBL) and to identify the patient-related and implant-related factors associated with PLCBL.
Methods
This retrospective cohort examined the dental records of patients who received at least one dental implant. PLCBL was defined as a reduction ⩾0.5 mm and severe PLCBL (primary variable) as a reduction ⩾1.5 mm in mesial and/or distal bone level, measured from the day of implant placement to uncovering or abutment installation/crown delivery. The incidence of PLCBL and patient and implant variables were recorded. Bivariate analysis and binary logistic regression identified factors associated with PLCBL ⩾0.5 mm and ⩾1.5 mm.
Results
A total of 746 dental implants placed in 361 patients from January 2011 to July 2021 was included in the analyses. Of the implants assessed, 24.4% (n = 182) exhibited PLCBL ⩾ 0.5 mm and 10.5% (n = 78) presented severe PLCBL (i.e., ⩾1.5 mm). Males (odds ratio [OR] = 1.85, 95% confidence interval [CI] = 1.11–3.07), patients with diabetes (OR = 3.33, 95% CI = 1.73–6.42), and those allergic to penicillin (OR = 3.13, 95% CI = 1.57–6.22) were more likely to experience severe PLCBL (p < 0.05). Implants placed in the anterior area (OR = 2.08, 95% CI = 1.16–3.73), with bone-level platform-abutment connection (OR = 4.73, 95% CI = 1.94–11.49) and inserted supracrestally (OR = 3.77, 95% CI = 1.84–7.72), presented a greater risk of developing severe PLCBL (p < 0.05). Implants placed in a previously grafted area presented a lower likelihood of developing severe PLCBL (OR = 0.489, 95% CI = 0.28–0.84).
Conclusion
The incidence of PLCBL ⩾ 0.5 mm and ⩾1.5 mm was 24.4% and 10.5%, respectively. Male sex, diabetes, allergy to penicillin, anterior location, bone-level platform-abutment connection, and supracrestal implant placement are potential risk factors for severe PLCBL. A previously grafted area is a potential protective factor.
