Methotrexate is widely used to control disease progression, but its effects on pain mechanisms are not fully understood. This study evaluated the antinociceptive effects of methotrexate on pain behavior, Wnt/β-catenin pathway expression, and glial activation in the trigeminal nociceptive pathway in rats with TMJ arthritis. Eighteen male Wistar rats were assigned to one of three groups: control, arthritic, or arthritic treated with methotrexate. Arthritis was induced by intra-articular injection of methylated bovine serum albumin. Pain behavior, inflammation, and joint damage were assessed. Immunoexpression of Wnt/β-catenin components and c-Fos was analyzed in the trigeminal ganglion and subnucleus caudalis, along with microglial activation. Methotrexate-treated arthritic rats showed increased pain threshold, reduced facial pain behaviors, and decreased inflammatory infiltrates, along with lower levels of tumor necrosis factor-α and interleukin-17 in the joint compared to untreated arthritic rats. Methotrexate also reduced c-Fos, Wnt-10b, β-catenin, and glutamine synthetase expression in the trigeminal ganglion and attenuated microglial activation in the subnucleus caudalis. These results indicate that methotrexate produces antinociceptive effects by modulating Wnt/β-catenin signaling and reducing glial activation in the trigeminal nociceptive pathway in rats with TMJ arthritis.","PeriodicalId":11983,"journal":{"name":"European Journal of Oral Sciences","volume":" ","pages":"e70041"},"PeriodicalIF":1.8,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145174289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study describes the expression of total IgE and specific IgE to six common antigens using the Uni-CAP system in healthy controls and OLP patients and investigates the IgG response to 14 food items to explore a possible association between OLP and a non-IgE mediated allergic reaction. Total IgE levels of the OLP patients were higher than seen in healthy controls. Two of 40 controls had IgE to house dust (HX2) compared to 8 of 40 patients with OLP; 2/40 controls had IgE to shrimp (F24) compared to 7/40 patients with OLP. Twenty-nine of 40 OLP patients were positive for IgG to 14 food types which was higher than the 20/40 seen in the control group. The findings indicate that OLP may be associated with hypersensitivity and food intolerance. Avoiding allergen exposure and administering appropriate desensitization treatments might facilitate the recovery of OLP.","PeriodicalId":11983,"journal":{"name":"European Journal of Oral Sciences","volume":" ","pages":"e70040"},"PeriodicalIF":1.8,"publicationDate":"2025-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145014168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following this trial phase, salivary fluoride monitoring continued for 2 weeks during which all 48 participants used 1450-ppm fluoride toothpaste in a wash-out phase. We investigated the temporal variability and longitudinal growth-based trajectories of salivary fluoride levels across study arms. During the trial phase, variability in the 5000-ppm arm exceeded that of the 1450-ppm arm. The best-fitting trajectories identified three clusters of participants following: low, medium or high salivary fluoride trajectories. Except for the 'high' cluster during the wash-out period, which featured only participants from the 5000-ppm trial arm, all clusters had participants from both trial arms. In conclusion, exploration of the variation and trajectories of salivary fluoride after 1450- and 5000-ppm fluoride toothpaste-use suggests non-constant responses to the initiation of and wash-out from the use of high-dosage fluoride toothpaste. This calls for the use of repeated period cross-over trial designs to investigate treatment effect heterogeneity. Reasons for and ways to minimize sources of individual variation in salivary fluoride levels are discussed.","PeriodicalId":11983,"journal":{"name":"European Journal of Oral Sciences","volume":" ","pages":"e70039"},"PeriodicalIF":1.8,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144999988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

FS-treated groups had higher Ra than HF-treated specimens. PICN showed higher Ra than other materials among the FS-treated groups. The HF-treated LDS showed the highest SBS. ZLS had the lowest SBS among the etched groups. Regardless of the material, the fs-laser treatment resulted in significantly higher SBS values than seen for controls.

This study raises awareness of core manufacturing defects and fosters the development of high-quality NiTi instruments without defects for clinical application. A scanning electron microscope with an acceleration voltage of 5 kV was used for fractographic analysis after cyclic fatigue testing. The fractographic analysis identified a compound core manufacturing defect, involving unmelted powder, and two interconnected failures. To the best of our knowledge, this is the first study to identify such compound core manufacturing defect in a NiTi instrument during fractographic analysis via scanning electron microscopy. The study underscores the need for detection and rectification of manufacturing defects, with methods such as X-ray computed tomography and hot isostatic pressing. The presence of core manufacturing defects in the NiTi instruments elevates the likelihood of premature clinical fracture, which may add to their inherent susceptibility to fracture in root canals due to cyclic fatigue and/or torsional stress.","PeriodicalId":11983,"journal":{"name":"European Journal of Oral Sciences","volume":" ","pages":"e70037"},"PeriodicalIF":1.8,"publicationDate":"2025-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144947766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Forty-eight sound human teeth were randomly divided into eight experimental groups, based on three factors: the type of SARC, the presence or absence of an MDP agent, and the presence or absence of multiple saliva exposures. The control group for each SARC received neither MDP agent nor multiple saliva contaminations. For each group, five teeth were sectioned to obtain 30-44 beams, followed by µTBS testing, fracture mode analysis, and scanning electron microscopy. Data were analyzed using one-way and two-way analysis of variance, Scheffé's test, and Weibull statistics. Under uncontaminated conditions, the application of MDP agents was found to significantly enhance the bond strength of both SARCs. Saliva contamination significantly reduced µTBS, regardless of the cement used. However, when MDP agents were applied prior to bonding, µTBS values remained comparable to those of uncontaminated controls, even after multiple saliva exposures. These results support the use of MDP agents to maintain adhesive integrity in the presence of repeated salivary contaminations, offering greater reliability in adverse clinical environments.","PeriodicalId":11983,"journal":{"name":"European Journal of Oral Sciences","volume":" ","pages":"e70036"},"PeriodicalIF":1.8,"publicationDate":"2025-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144872104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Corresponding soft tissue deviations were clinically measured. Perception of facial asymmetry was assessed using a visual analog scale (VAS) based on frontal photographs rated by 20 orthodontists and 20 members of the general population. Patients were categorized into four groups based on chin asymmetry (1–2 mm, 3–4 mm, 5–7 mm, > 7 mm). The findings showed that the skeletal asymmetry was greater than soft tissue asymmetry, indicating soft tissue compensation, particularly at Ag and Me. Orthodontists rated facial asymmetry more critically, but for chin shifts > 5 mm, both groups had similar perceptions. It was concluded that soft tissue compensations, especially in the lower face, help to mask skeletal asymmetry.
