Objective

The potential role of autoantibodies targeting desmosomal proteins, particularly desmoglein 1 (Dsg-1) and desmoglein 3 (Dsg-3), in modulating disease severity and epithelial integrity in oral lichen planus (OLP) remains a subject of growing interest. Distinct patterns of anti-Dsg-1 and anti-Dsg-3 autoantibodies across OLP subtypes may correlate with disease progression. This scoping review investigates the expression patterns of circulating anti-Dsg-1 and anti-Dsg-3 autoantibodies in reticular, erosive, and ulcerative forms of OLP to elucidate their potential roles in epithelial disruption and disease advancement.

Design

Following PRISMA guidelines, a systematic search of four electronic databases was conducted. Eligible studies included case reports, case series, case-control and cross-sectional studies that reported serum levels of anti-Dsg-1 and anti-Dsg-3 autoantibodies in OLP patients.

Results

Reticular-type OLP showed variable anti-Dsg-1 and anti-Dsg-3 autoantibody levels, with some patients testing positive while others were negative, indicating an inconsistent involvement of desmosomal autoimmunity in this milder form of the disease.

In erosive-type OLP, the presence of both autoantibodies indicated deeper epithelial damage and an active autoimmune response. Interestingly, ulcerative-type OLP consistently tested negative for both antibodies despite extensive epithelial breakdown, implying a potential shift from desmosomal autoimmunity to chronic inflammation–driven tissue destruction that could compromise human health.

Conclusion

These findings suggest a potential continuum in which reticular OLP may progress to erosive OLP, with Dsg-3 autoantibodies as a possible early marker of worsening pathology. Ulcerative OLP appears to represent a late-stage, inflammation-driven phenotype with minimal autoantibody involvement. Given the limited and heterogeneous data, these observations are preliminary and should be interpreted cautiously.

目的：针对桥粒蛋白的自身抗体，特别是桥粒蛋白1 （Dsg-1）和桥粒蛋白3 (Dsg-3)，在调节口腔扁平苔藓（OLP）疾病严重程度和上皮完整性方面的潜在作用仍然是一个越来越受关注的主题。不同OLP亚型的抗dsg -1和抗dsg -3自身抗体的不同模式可能与疾病进展相关。本综述研究了网状、糜烂和溃疡性OLP中循环抗dsg -1和抗dsg -3自身抗体的表达模式，以阐明它们在上皮破坏和疾病进展中的潜在作用。设计：按照PRISMA的指导方针，系统地检索了四个电子数据库。符合条件的研究包括报告OLP患者血清抗dsg -1和抗dsg -3自身抗体水平的病例报告、病例系列、病例对照和横断面研究。结果：网状型OLP显示抗dsg -1和抗dsg -3自身抗体水平变化，一些患者检测呈阳性，而另一些患者检测呈阴性，表明在这种较轻形式的疾病中，桥粒体自身免疫的参与不一致。在糜烂型OLP中，两种自身抗体的存在表明更深的上皮损伤和积极的自身免疫反应。有趣的是，尽管有广泛的上皮破坏，溃疡型OLP的两种抗体检测结果始终呈阴性，这意味着从桥粒体自身免疫到慢性炎症驱动的组织破坏的潜在转变，可能危及人类健康。结论：这些发现表明网状OLP可能发展为糜烂性OLP， Dsg-3自身抗体可能是病理恶化的早期标志。溃疡性OLP似乎代表了一种晚期，炎症驱动的表型，自身抗体参与最小。考虑到有限和异质性的数据，这些观察结果是初步的，应该谨慎解释。

Objective

To investigate the relationship of nutrient canals with jaw cysts, trabecular bone density, and dental regions using cone-beam computed tomography (CBCT).

Design

This retrospective study analyzed 120 CBCT images from 60 patients with unilateral jaw cysts. Nutrient canals were identified and localized on both the cyst-affected side and contralateral, unaffected side of the jaw for each patient. Alveolar trabecular structure was assessed by comparing Hounsfield Unit (HU) values between affected and unaffected sides. Statistical analyses included paired t-tests, Fisher’s exact test, and intra-observer reliability assessment.

Results

Nutrient canals were significantly more prevalent in cyst-affected jaw regions. Their presence was associated with areas exhibiting pericystic trabecular sclerosis, as reflected by elevated HU values. While nutrient canals were commonly observed in the anterior regions of both healthy and affected jaws, their presence in premolar and molar regions was restricted to cyst-affected areas.

Conclusions

Nutrient canals, typically found in the anterior jaws, appear to develop in posterior regions in association with jaw cysts, particularly in the presence of trabecular sclerosis. Their identification on CBCT scans is important for treatment planning and for minimizing potential surgical complications.

目的应用锥形束ct （cone-beam computed tomography， CBCT）研究营养管与颌骨囊肿、骨小梁骨密度及牙区之间的关系。本回顾性研究分析了60例单侧颌囊肿患者的120张CBCT图像。在每个患者的受囊肿影响的一侧和对侧未受影响的一侧颌骨上确定并定位营养管。通过比较患侧和未患侧的Hounsfield Unit （HU）值来评估肺泡小梁结构。统计分析包括配对t检验、Fisher精确检验和观察者内部信度评估。结果在患囊肿的颌区，营养管明显增多。它们的存在与表现为囊周小梁硬化的区域有关，这可以通过HU值升高来反映。虽然营养管通常在健康和患病颌骨的前区观察到，但它们在前磨牙和磨牙区域的存在仅限于囊肿影响区域。结论：在颌骨囊肿患者中，特别是在小梁硬化患者中，通常在前颚发现的三通管出现在下颌后部。在CBCT扫描上识别它们对于治疗计划和减少潜在的手术并发症非常重要。

Objectives

This study aimed to elucidate the regulatory effects and mechanisms of Ganoderic acid A (GAA) on Porphyromonas gingivalis (P. gingivalis)-induced expression of adhesion molecules in human gingival fibroblasts (hGFs) and periodontal tissues, focusing on NLRP6 inflammasome modulation.

Design

HGFs were stimulated with P. gingivalis strain W83. The expression levels of NLRP6, caspase-1, IL-1β,IL-18 and adhesion molecules ICAM-1 & VCAM-1 were analyzed by RT-PCR, Western blotting and ELISA, with or without GAA pretreatment. To further explore the regulatory role of GAA on the NLRP6 inflammasome, NLRP6 overexpression assays were performed in hGFs, followed by assessment of ICAM-1 and VCAM-1 expressions. Additionally, a ligature-induced periodontitis mice model was established to evaluate the effects of GAA on NLRP6 expression and inflammatory cell infiltration in periodontal tissues.

Results

GAA exhibited no cytotoxicity toward hGFs at low concentrations (within 16 μM). GAA pretreatment significantly inhibited P. gingivalis-induced activation of the NLRP6 inflammasome. Beyond IL-1β and IL-18, it also reduced ICAM-1 and VCAM-1 expression at both mRNA and protein levels. Overexpression of NLRP6 increased the expression of NLRP6 inflammasome components and adhesion molecules, whereas GAA treatment effectively suppressed these elevations. Furthermore, GAA administration markedly downregulated NLRP6 expression and attenuated inflammatory cell infiltration and periodontal inflammation in the mice periodontitis model.

Conclusions

GAA attenuates P. gingivalis-induced expression of adhesion molecules by inhibiting NLRP6 inflammasome activation in gingival fibroblasts and periodontal tissues, thereby alleviating inflammatory cell infiltration. These findings suggest the potential of GAA as a therapeutic agent for the management of periodontal inflammation.

目的：研究灵芝酸A （GAA）对牙龈卟啉单胞菌（P. gingivalis）诱导的人牙龈成纤维细胞（hGFs）和牙周组织中粘附分子表达的调控作用及其机制，重点研究NLRP6炎症小体的调控作用。设计：用牙龈假单胞菌菌株W83刺激hgf。采用RT-PCR、Western blotting和ELISA检测GAA预处理前后NLRP6、caspase-1、IL-1β、IL-18和粘附分子ICAM-1、VCAM-1的表达水平。为了进一步探讨GAA对NLRP6炎症小体的调节作用，我们在hgf中进行NLRP6过表达测定，随后评估ICAM-1和VCAM-1的表达。建立结扎性牙周炎小鼠模型，观察GAA对牙周组织NLRP6表达及炎症细胞浸润的影响。结果：低浓度（16 μM以内）GAA对hGFs无细胞毒性。GAA预处理可显著抑制牙龈假单胞菌诱导的NLRP6炎性体的活化。除IL-1β和IL-18外，它还能在mRNA和蛋白水平上降低ICAM-1和VCAM-1的表达。NLRP6的过表达增加了NLRP6炎症小体成分和粘附分子的表达，而GAA治疗有效地抑制了这些升高。此外，GAA可显著下调小鼠牙周炎模型中NLRP6的表达，减轻炎症细胞浸润和牙周炎症。结论：GAA通过抑制NLRP6炎症小体在牙龈成纤维细胞和牙周组织中的活化，减弱牙龈假单胞菌诱导的粘附分子表达，从而减轻炎症细胞浸润。这些发现提示了GAA作为牙周炎症治疗药物的潜力。

Objective

Oral candidiasis is a common opportunistic infection caused by Candida albicans, particularly in individuals with local or systemic risk factors. This study aimed to investigate how antifungal therapy affects the composition of the oral bacterial microbiome.

Design

Unstimulated saliva samples were collected from ten patients diagnosed with acute pseudomembranous oral candidiasis before and after fluconazole treatment. Microbiome profiles were assessed using 16S rRNA gene sequencing. Quantitative PCR was performed to validate changes in specific bacterial species.

Results

Alpha diversity did not change significantly, whereas beta-diversity analyses indicated modest compositional shifts. Antifungal therapy was associated with an increase in Streptococcus salivarius, a commensal linked to mucosal health. The signal was confirmed by species-specific qPCR in paired samples.

Conclusions

Fluconazole treatment for oral candidiasis induces modest shifts in the oral bacterial community, particularly increasing the abundance of S. salivarius. These changes may reflect partial recovery of microbial homeostasis, supporting the role of microbiome monitoring and probiotic approaches in post-treatment care.

目的口腔念珠菌病是一种常见的由白色念珠菌引起的机会性感染，特别是在有局部或全身危险因素的个体中。本研究旨在探讨抗真菌治疗如何影响口腔细菌微生物组的组成。设计收集10例急性假膜性口腔念珠菌病患者氟康唑治疗前后的非刺激唾液样本。采用16S rRNA基因测序评估微生物组谱。采用定量PCR验证特定菌种的变化。结果α - α多样性变化不显著，β - α多样性变化不大。抗真菌治疗与唾液链球菌的增加有关，这是一种与粘膜健康相关的共生菌。该信号在配对样本中被物种特异性qPCR证实。结论氟康唑治疗口腔念珠菌病可引起口腔细菌群落的适度变化，特别是增加了唾液链球菌的丰度。这些变化可能反映了微生物稳态的部分恢复，支持微生物组监测和益生菌方法在治疗后护理中的作用。

Objectives

In this study, we aimed to explore the protein content of bacterial extracellular vesicles (bEVs) from three strains of Porphyromonas gingivalis, an anaerobic gram-negative bacterium closely associated with periodontitis. Additionally, we aimed to investigate the effects of bEV uptake on human oral fibroblasts, to better understand the role of these vesicles in the pathogenesis of periodontitis.

Design

Liquid chromatography-mass spectrometry was performed on bEVs from three strains of P. gingivalis with different virulence: ATCC 33277, A7A1–28, and W83. Three key proteins associated with virulence were validated using dot blot. Proliferation and viability of human oral fibroblasts after incubation with bEVs were assessed at different timepoints and different concentrations of bEVs.

Results

A total of 307 proteins were identified in the bEVs from the three strains of P. gingivalis. Among those were several relevant for virulence, for example gingipains, fimbriae, and peptidyl-arginine deiminase (PPAD). When oral fibroblasts were exposed to bEVs from A7A1–28 or W83, proliferation was significantly affected after 12 and 24 h at one bEV concentration. Furthermore, viability was significantly affected by bEVs from W83 at several timepoints and bEV concentrations. bEVs from ATCC 33277 did not induce any significant changes.

Conclusion

Several proteins associated with virulence were detected in bEVs from all three strains of P. gingivalis, with varying abundance. Uptake of these bEVs can influence human cells, as exemplified by changes in viability and proliferation.

目的：在本研究中，我们旨在探讨三株牙龈卟啉单胞菌（一种与牙周炎密切相关的革兰氏阴性厌氧菌）的细菌细胞外囊泡（bEVs）的蛋白质含量。此外，我们旨在研究bEV摄取对人口腔成纤维细胞的影响，以更好地了解这些囊泡在牙周炎发病机制中的作用。设计：采用液相色谱-质谱法对三株不同毒力的牙龈假单胞菌ATCC 33277、A7A1-28和W83的bev进行分析。3个与毒力相关的关键蛋白采用点印迹法进行了验证。研究了不同时间点、不同浓度bev对人口腔成纤维细胞增殖和活力的影响。结果：从3株牙龈假单胞菌的bev中共鉴定出307个蛋白。其中有几个与毒力有关，例如牙龈痛、菌毛和肽精氨酸脱亚胺酶（PPAD）。当口腔成纤维细胞暴露于A7A1-28或W83的bEV时，在一个bEV浓度下，12和24 h后，增殖受到显著影响。此外，在不同时间点和不同浓度下，W83的bEV对细胞活力有显著影响。ATCC 33277的纯电动汽车没有引起任何显著的变化。结论：在三株牙龈假单胞菌的bev中均检测到几种与毒力相关的蛋白，且丰度不同。这些bev的摄取可以影响人类细胞，如活力和增殖的变化。

A pan-cancer analysis of TCGA datasets was performed to evaluate TWF1 expression and prognostic significance, followed by validation using quantitative real-time PCR (qPCR) and immunohistochemistry (IHC) in clinical HNSCC specimens. Functional assays (CCK-8, colony formation, wound healing, and Transwell invasion) were conducted following siRNA-mediated TWF1 knockdown in SCC9 cells. Additionally, the same functional assays were conducted in an HSC3 cell model overexpressing TWF1 to further evaluate its oncogenic function. The involvement of the AKT signaling pathway was examined by Western blot and validated through rescue experiments with the AKT activator SC79.

Results

TWF1 was found to be upregulated in 13 cancer types, including HNSCC. Elevated TWF1 expression, advanced T stage, and lymph node metastasis were identified as independent prognostic indicators in HNSCC. qPCR confirmed increased TWF1 expression, and IHC showed higher TWF1 protein levels in HNSCC tissues. TWF1 knockdown suppressed SCC9 cell proliferation, migration, and invasion, and reduced phosphorylated AKT levels. Conversely, TWF1 overexpression in HSC3 cells promoted proliferation, migration, and invasion while enhancing AKT phosphorylation. SC79 treatment partially reversed the malignant phenotypes suppressed by TWF1 knockdown, supporting TWF1’s regulatory role through AKT phosphorylation.

Conclusion

TWF1 acts as an oncogenic driver in HNSCC, promoting tumor progression through the AKT signaling pathway. It may serve as a potential therapeutic target in precision medicine for HNSCC.

目的：探讨Twinfilin actin-binding protein 1 （TWF1）驱动头颈部鳞状细胞癌（HNSCC）恶性进展的分子机制。设计：对TCGA数据集进行泛癌分析，评估TWF1的表达和预后意义，随后使用定量实时PCR （qPCR）和免疫组织化学（IHC）对临床HNSCC标本进行验证。在SCC9细胞中sirna介导的TWF1敲除后进行功能测定（CCK-8、菌落形成、伤口愈合和Transwell侵袭）。此外，在过表达TWF1的HSC3细胞模型中进行了相同的功能测定，以进一步评估其致癌功能。通过Western blot检测AKT信号通路的参与情况，并通过AKT激活剂SC79的拯救实验进行验证。结果：在包括HNSCC在内的13种癌症类型中发现TWF1表达上调。TWF1表达升高、T分期晚期和淋巴结转移被确定为HNSCC的独立预后指标。qPCR证实TWF1表达升高，IHC显示HNSCC组织中TWF1蛋白水平升高。TWF1敲除抑制SCC9细胞增殖、迁移和侵袭，降低磷酸化AKT水平。相反，在HSC3细胞中，TWF1过表达促进增殖、迁移和侵袭，同时增强AKT磷酸化。SC79治疗部分逆转了TWF1敲低抑制的恶性表型，支持了TWF1通过AKT磷酸化的调节作用。结论：TWF1在HNSCC中发挥致癌驱动作用，通过AKT信号通路促进肿瘤进展。它可能成为HNSCC精准医学的潜在治疗靶点。

Objective

To evaluate, in vitro, the topical effect of polysaccharide cashew gum (PLS-cg) on dentine subjected to erosive cycles that simulate refluxate contact in the oral cavity.

Design

Human dentine blocks were prepared, standardized, and randomly assigned to one of three treatment groups (n = 10): control group (C) without treatment, commercial dental varnish (CDV) 5 % NaF fluoride varnish, and PLS-cg extract (experimental group). The baseline enamel superficial microhardness (HK) and roughness (Ra) were assessed. The dentin was subjected to erosive cycles (6 × 5 min/day for 9 days) using a hydrochloric acid–pepsin solution (pH 2; 0.75-mg/mL pepsin). Surface roughness (Ra), microhardness (HK), percentage surface hardness loss (%SHL), and topographic analysis with scanning electron microscopy (SEM) were used to evaluate the protective heteropolysaccharide effect. Predictive molecular docking simulations were used to investigate possible interactions between PLS-cg and metalloproteinases (MMP2 and MMP9). The data were analyzed with two-way analysis of variance, t test, Pearson’s correlation, and Tukey’s test (p < 0.05).

Results

PLS-cg preserved HK significantly better than the control group (p < 0.001), with the lowest %SHL (-14.04 ± 8.22) and minimal Ra changes (0.124 ± 0.005). Pearson’s correlation between Ra and %SHL was significant and positive (0.7740, p < 0.001). SEM analysis revealed more prominent dentinal tubule openings in the control group, whereas CDV and PLS-cg showed tubule obliteration. Molecular docking identified possible interactions between PLS-cg and MMPs.

Conclusion

The findings indicate that PLS-cg may reduce dentine erosion caused by supraesophageal manifestations of gastroesophageal reflux disease.

目的：体外评价腰果多糖（PLS-cg）对牙本质在模拟口腔内反流接触的侵蚀循环中的局部作用。设计：将人牙本质块制备、标准化并随机分配到三个治疗组（n = 10）中的一个：对照组(C)未治疗，商用牙清漆（CDV） 5 % NaF氟化物清漆和PLS-cg提取物（实验组）。评估基线牙釉质表面显微硬度（HK）和粗糙度（Ra）。使用盐酸-胃蛋白酶溶液（pH 2； 0.75 mg/mL胃蛋白酶）对牙本质进行侵蚀循环（6 × 5 分钟/天，持续9天）。采用表面粗糙度（Ra）、显微硬度（HK）、表面硬度损失率（%SHL）和扫描电镜形貌分析（SEM）来评价杂多糖的保护作用。预测分子对接模拟用于研究PLS-cg与金属蛋白酶（MMP2和MMP9）之间可能的相互作用。对数据进行双向方差分析、t检验、Pearson相关和Tukey检验（p ）结果：PLS-cg保存HK显著优于对照组（p ）结论：PLS-cg可减少胃食管反流病食管上表现引起的牙本质糜烂。

Objective

To identify m1A-modified genes with diagnostic potential linking periodontitis and type 2 diabetes mellitus (T2DM) by integrating bioinformatics and experimental validation.

Design

Transcriptomic data for periodontitis and T2DM patients were integrated from the GEO database to analyze m1A-related gene expression. A diagnostic model was constructed using ridge and logistic regression. Gene function enrichment, immune infiltration, and protein-protein interaction analyses explored m1A regulatory mechanisms based on m1A scoring and patient clustering models. Gingival tissue samples were collected from periodontitis patients and healthy controls, and a streptozotocin-induced diabetic β-cell model was established. qRT-PCR was performed to validate candidate genes (RRP8, ALKBH3, MAK16, and DDX18). Statistical comparisons were conducted using the non-parametric Mann–Whitney U test.

Results

Several m1A-related genes were differentially expressed in both periodontitis and T2DM. RRP8 and ALKBH3 had high predictive value, with area under the curve (AUC) values of 0.80 (periodontitis) and 0.72 (T2DM). m1A scoring and patient clustering models effectively distinguished patient groups with distinct transcriptomic and immune profiles. Hub genes MAK16 and DDX18 showed consistent expression patterns and strong correlations with immune infiltration. qRT-PCR confirmed significant downregulation of RRP8, ALKBH3, MAK16, and DDX18 in inflamed gingival tissues, and upregulation in the diabetic cell model (p < 0.05), supporting the bioinformatics findings.

Conclusions

This integrative study identifies key m1A-modified genes potentially linking periodontitis and diabetes. The combination of bioinformatics analysis and experimental validation highlights their potential as diagnostic biomarkers and provides novel insights into shared molecular mechanisms of these comorbid conditions.

目的：通过生物信息学和实验验证相结合的方法，鉴定具有牙周炎与2型糖尿病（T2DM）诊断潜力的m1a修饰基因。设计：从GEO数据库中整合牙周炎和T2DM患者的转录组学数据，分析m1a相关基因表达。采用岭回归和逻辑回归建立诊断模型。基于m1A评分和患者聚类模型，基因功能富集、免疫浸润和蛋白-蛋白相互作用分析探索了m1A的调控机制。收集牙周炎患者和健康对照者的牙龈组织标本，建立链脲佐菌素诱导的糖尿病β细胞模型。采用qRT-PCR验证候选基因（RRP8、ALKBH3、MAK16和DDX18）。采用非参数Mann-Whitney U检验进行统计比较。结果：几个m1a相关基因在牙周炎和T2DM中均有差异表达。RRP8和ALKBH3具有较高的预测价值，曲线下面积（AUC）值分别为0.80（牙周炎）和0.72 （T2DM）。m1A评分和患者聚类模型有效区分具有不同转录组和免疫谱的患者组。枢纽基因MAK16和DDX18表达模式一致，且与免疫浸润有很强的相关性。qRT-PCR证实了炎症牙龈组织中RRP8、ALKBH3、MAK16和DDX18的显著下调，以及糖尿病细胞模型中的上调（p ）。结论：这项综合研究鉴定了关键的ma1修饰基因，可能与牙周炎和糖尿病有关。生物信息学分析和实验验证的结合突出了它们作为诊断性生物标志物的潜力，并为这些共病的共同分子机制提供了新的见解。

Objectives

This systematic review and meta-analysis aimed to investigate the potential of fucose as a biomarker for oral potentially malignant disorders (OPMDs) and oral squamous cell carcinoma (OSCC).

Design

Relevant articles were searched across multiple databases, including PubMed, Scopus, Google Scholar, Science Direct, and Clinical Key. Twenty-three studies that met the eligibility criteria were included for qualitative review; out of which, 20 studies that provided data for comparison between study and control groups were further subjected to meta-analysis.

Results

The analysis revealed significantly high fucose levels in the saliva of OPMD patients (p = 0.013) and OSCC patients (p = 0.003) compared to healthy controls. Additionally, fucose levels were elevated in the serum of patients with OSCC (p < 0.001) and oral leukoplakia (p = 0.027) compared to controls.

Conclusion

The findings of this meta-analysis suggest that fucose could serve as a potential biomarker for OPMDs and OSCC. However, the presence of significant heterogeneity in serum evaluation and the limited studies focusing on saliva indicate the need for further investigation.

目的：本系统综述和荟萃分析旨在探讨病灶作为口腔潜在恶性疾病（OPMDs）和口腔鳞状细胞癌（OSCC）生物标志物的潜力。设计：在多个数据库中检索相关文章，包括PubMed、Scopus、谷歌Scholar、Science Direct和Clinical Key。23项符合资格标准的研究被纳入定性评价；其中，有20项研究提供了实验组与对照组比较的数据，进一步进行meta分析。结果：与健康对照组相比，OPMD患者（p = 0.013）和OSCC患者（p = 0.003）唾液中的病灶水平显著升高。此外，OSCC患者血清中的病灶水平升高（p ）。结论：本荟萃分析结果表明，病灶可作为opmd和OSCC的潜在生物标志物。然而，在血清评估中存在显著的异质性和有限的研究集中在唾液表明需要进一步的研究。
