Preoperative imaging (CT/MRI) is vital for assessment but often yields false results. This study examines the concordance between preoperative imaging and postoperative pathology and identifies factors influencing imaging accuracy.Methods: A retrospective cohort study from 2014 to 2023 included patients with head and neck malignancies. Clinical and radiological data were analyzed, and the random forest algorithm was utilized for indeterminate cases.Results: Analyzing 1129 records, 26.1% had indeterminate imaging. Imaging accuracy for definitive findings was 72.8%, sensitivity 57.2%, and specificity 86.0%. Logistic regression highlighted alcohol, T, and clinical stage as accuracy influencers. The indeterminate group showed a link between multiple enlarged lymph nodes and positivity. A nomogram achieved 67.5% accuracy. The random forest model, focusing on lymph node diameter, stage, and T classification, improved accuracy to 75.5% over logistic regression.Conclusion: Our study shows moderate imaging-pathology concordance. Key predictors like lymph node size suggest refining criteria with machine learning could enhance head and neck cancer diagnosis. These results could guide more accurate preoperative imaging assessments, leading to better surgical planning and patient outcomes. Subsequent exploration of adjusting lymph node size thresholds or integrating novel imaging technologies would be useful.","PeriodicalId":19615,"journal":{"name":"Oral diseases","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143634377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Descriptive statistics were analyzed using SPSS, with Chi-square and Fisher exact tests, alongside logistic regression for appropriate questions.Results: A total of 403 dentists participated, with 8% reporting professional prejudices against transgender individuals. Dentists who associated transgender patients with increased clinical infection rates were statistically more likely to hold prejudices (p < 0.05). Additionally, 60.2% expressed interest in training to enhance communication with transgender patients. Female dentists were significantly more likely to be open to such training (p < 0.05).Conclusion: The findings highlight a strong desire among dentists for training to improve communication with transgender patients, along with a lack of knowledge about key topics such as gender-affirming, endogenous hormones, and their oral health implications.

This study investigates the impact of dasatinib and quercetin (D + Q) treatment on senescent cells (SnCs), senescence-associated secretory phenotype (SASP), and neutrophil infiltration in aged alveolar bone, aiming to develop new strategies for combating age-related bone resorption.Methods: C57BL/6 mice (2 and 18 months) were used to examine alveolar bone resorption, inflammaging, and neutrophil infiltration. Aged mice received D + Q treatment to assess therapeutic effects. Key measurements included cementoenamel junction to the alveolar bone crest (CEJ-ABC) distance, periodontal ligament (PDL) thickness, osteometabolism markers, SnCs accumulation, SASP expression, and neutrophil infiltration.Results: Aged alveolar bone showed increased CEJ-ABC distance, atrophied periodontal ligament, and unbalanced osteometabolism, along with elevated SnCs, SASP, and neutrophils compared to young controls. D + Q treatment improved these conditions by reducing CEJ-ABC distance, enhancing periodontal ligament health, and boosting bone metabolism. It also lowered the expression of SnCs, SASP, and neutrophil markers.Conclusion: D + Q treatment effectively mitigates alveolar bone aging by clearing SnCs, lowering SASP levels, and reducing neutrophil aggregation, presenting a novel approach for age-related bone resorption.","PeriodicalId":19615,"journal":{"name":"Oral diseases","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143573152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our study aims to elucidate the interplay between macrophages and Piezo2 in temporomandibular joint osteoarthritis (TMJOA) chronic pain.Materials and methods: We induced TMJOA chronic pain in rats via articular injection of monosodium iodoacetate (MIA). We then depleted macrophages using clodronate liposomes and overexpressed Piezo2 in trigeminal ganglion (TG) neurons with adeno-associated virus 9 (AAV9)-Piezo2 in TMJOA rats. To explore the connection between macrophages and Piezo2, we employed immunofluorescence, in vitro studies, and the Rat Grimace Scale (RGS) to evaluate pain thresholds in TMJOA rats.Results: A positive correlation was observed between macrophage infiltration and Piezo2 upregulation in TG neurons of TMJOA rats. Depletion of infiltrated macrophages downregulated Piezo2 in TG neurons, while Piezo2 overexpression negated the pain-relieving effects of infiltrated macrophage depletion in TMJOA rats. Macrophages primarily influenced Piezo2 expression in IB4 + - TG neurons of TMJOA chronic pain rats. Ex vivo studies revealed that infiltrated macrophage-derived IL-1β and TNF-α cytokines activate Dil + -TG neurons by upregulating Piezo2 in TMJOA rats.Conclusions: Infiltrated macrophages exacerbate MIA-induced TMJOA chronic pain by upregulating Piezo2 expression in IB4+-TG neurons.","PeriodicalId":19615,"journal":{"name":"Oral diseases","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143573216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A narrative overview of current literature was undertaken to synthesize the contexts with elaboration and summary.Results: The crosstalk between cancer cells and the tumor stroma, a major driver of tumor progression and metastasis, has increasingly been unveiled. This review highlights the tumor-to-stroma ratio (TSR) as a valuable prognostic marker in OSCC, with high stromal content (TSR > 50%) linked to poorer survival. On the other hand, tumor-infiltrating lymphocytes are associated with improved prognosis and longer survival. Furthermore, emerging markers, such as cancer-associated fibroblasts and desmoplastic reactions, play significant roles in promoting tumor invasiveness and resistance to therapy. The review identifies gaps in current evidence and proposes directions for future research to further clarify the prognostic utility of stromal components.Conclusions: Stromal markers provide valuable prognostic insights into OSCC and could enhance clinical decision-making, emphasizing the complexity of OSCC progression.","PeriodicalId":19615,"journal":{"name":"Oral diseases","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143542948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PCR and Sanger sequencing were used to detect mutations, followed by statistical analysis to assess correlations between mutations and clinical variables.Results: BRAF V600E mutations were significantly prevalent, occurring in 92% (59/64) of mandibular AMs compared to 40% (10/25) in maxillary AMs. SMO mutations were found in 20% (5/25) of maxillary and 3.1% (2/64) of mandibular AMs. FGFR2 mutations were detected in six maxillary and two mandibular AMs, while RAS mutations were present in four maxillary and one mandibular AM. No detectable HRAS, NRAS(G12), or CTNNB1 mutations were observed. BRAF mutations showed mutual exclusivity with SMO and FGFR2 mutations.Conclusion: The high prevalence of BRAF V600E mutations, particularly in mandibular AMs, suggests its potential as a diagnostic and therapeutic target.
