Fifteen healthy adults participated in a double-blind crossover study, brushing with either a 1450 ppm F or 5000 ppm F dentifrice. Saliva was collected at pre-brushing, immediately after brushing, and at 5 min, 2, 4, and 8 h post-brushing in both periods. Fluoride concentrations were measured using an ion-selective electrode and analyzed with the Wilcoxon matched-pairs and Kruskal-Wallis tests (5% significance). At pre-brushing, no statistically significant differences were detected between groups. Both dentifrices increased salivary fluoride concentrations, reaching peak levels immediately after brushing. However, the high-fluoride dentifrice consistently maintained significantly higher concentrations compared with the regular formulation. During the nocturnal period, elevated fluoride levels persisted for up to 8 h with the high-fluoride dentifrice, whereas concentrations returned to pre-brushing levels within 2 h with the regular formulation. In conclusion, fluoride bioavailability was greater and more sustained during the nocturnal period than during the diurnal period, emphasizing the influence of brushing time on salivary fluoride retention. High-fluoride dentifrice further enhanced this effect across both periods.","PeriodicalId":11983,"journal":{"name":"European Journal of Oral Sciences","volume":" ","pages":"e70079"},"PeriodicalIF":2.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13181523/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147354431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluated biomimetic remineralisation strategies that aimed to enhance adhesive durability: polyacrylic acid-stabilised amorphous calcium phosphate-loaded mesoporous silica nanoparticles (PA-ACP/MSN) incorporated at 15 vol% into the primer phases of two commercially available two-step universal adhesives (G2 Bond Universal and OptiBond eXTRa Universal) applied in etch-and-rinse mode, with or without phosphorylation pretreatment (5% PA + 5% sodium trimetaphosphate). Adhesive-dentine specimens were characterised using microtensile bond strength (µTBS), confocal Raman microscopy (Phosphate peaks; Resin CH2 peaks; Mineral-Matrix ratio MMR), nanoindentation across the hybrid layer and dye-assisted micropermeability assays. The incorporation of PA-ACP/MSN did not adversely affect the immediate µTBS of either adhesive. After ageing, the biomimetic treatment group demonstrated enhanced phosphate content, improved micro-mechanical properties, preservation of resin characteristics, a higher elastic modulus across the hybrid layer and a marked reduction in permeability relative to the control group. Adding the phosphorylation pretreatment step conferred no additional benefit over PA-ACP/MSN alone. These findings indicated that embedding PA-ACP/MSN in universal-adhesive primers promoted remineralisation, stiffened and sealed the hybrid layer, and preserved bonding effectiveness without adding clinical complexity, supporting a practical path to durable, bioactive/biomimetic resin-dentine interfaces.","PeriodicalId":11983,"journal":{"name":"European Journal of Oral Sciences","volume":" ","pages":"e70078"},"PeriodicalIF":2.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147303845","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}

All groups underwent 15 days of smoke exposure, which was then continued for another 15 days in the smoking-only (SO) and smoking + vitamin C. The vitamin C group received 200 mg/kg/day of intraperitoneal vitamin C; the saline group received 0.9% NaCl. On Day 28, rats were euthanized for biochemical and immunohistochemical analyses. The SO group showed significantly elevated cotinine and tumor necrotizing factor-α levels. Reactive oxygen species, thiobarbituric acid reacting substances, and catalase activity were also significantly higher in this group. Vitamin C groups showed lower levels, with no significant differences between them. Ferric-reducing antioxidant power levels in the saline group were significantly higher than in the SO group. Immunohistochemical analysis revealed significant differences in Ki-67 and matrix metalloproteinase-8-positive-stained cells between SO and vitamin C groups. Within the limitations of this model, vitamin C supplementation was associated with reduced oxidative stress and inflammatory responses in smoke-exposed rats with periodontitis. These results suggest vitamin C may modulate host antioxidant defense, though further clinical confirmation is needed.","PeriodicalId":11983,"journal":{"name":"European Journal of Oral Sciences","volume":" ","pages":"e70080"},"PeriodicalIF":2.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147431716","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}

Statistical analysis was conducted using one-way anova and Tukey's test at a 95% significance level. FQhg showed the highest cyclic fatigue resistance, followed by FQgh, FQnh, and PTG (p < 0.05), while no significant differences were found in torsional strength, toughness, or distortion angle among the FQ groups. PTG showed higher torsional strength and bending stiffness, likely due to its different cross-sectional design and taper. DSC analysis revealed minor differences in austenite transformation temperatures between FQhg and FQgh. The sequence of heat treatment and grinding significantly influenced cyclic fatigue resistance, with post-heat-treatment grinding (FQhg) providing superior performance; however, its impact on other mechanical properties was limited. The clinical relevance of processing sequence appears minimal compared to factors such as cross-sectional design and heat treatment.","PeriodicalId":11983,"journal":{"name":"European Journal of Oral Sciences","volume":" ","pages":"e70074"},"PeriodicalIF":2.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147283221","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}

Titanium implants were placed in the maxillae of the mice, and the osseointegration process was analyzed using micro-CT to evaluate bone volume and mineral density, histological staining to visualize bone-to-implant contact (BIC), RT-qPCR to detect osteogenic gene expressions, and enzyme-linked immunosorbent assay to assess inflammatory cytokine levels. Results showed that Cxcl9 overexpression significantly impaired osseointegration, as evidenced by reduction in bone volume, bone mineral density, and BIC. This was accompanied by an increase in osteoclast numbers. Moreover, Cxcl9 overexpression suppressed expression of osteogenic genes and resulted in elevated pro-inflammatory cytokines, including TNFα and IL1β. Conversely, Cxcl9 knockdown improved osseointegration, suggesting that CXCL9 is a negative regulator of bone remodeling at implant sites. Further, CXCL9 expression impairs titanium implant osseointegration. This highlights CXCL9 as a potential therapeutic target to improve dental implant osseointegration, particularly in patients with inflammatory conditions.","PeriodicalId":11983,"journal":{"name":"European Journal of Oral Sciences","volume":" ","pages":"e70084"},"PeriodicalIF":2.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147354412","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}

Monotonic testing was performed to define the fatigue parameters, then a cyclic fatigue test was conducted. Fracture analysis was performed using a stereomicroscope. Fatigue failure loads and the number of cycles to failure were analysed using the Kaplan-Meier and Mantel-Cox (Log Rank) test. Survival rates were calculated for each 'step' of the fatigue test. Fracture types were analysed descriptively. Teeth treated with AHP and restored with endocrowns achieved better results in both load resistance and number of cycles, compared to the AHP-MOD group and teeth filled with AHPB regardless of the restoration used (p < 0.05). However, there was no significant difference when these groups were compared to the control (p > 0.05). Most failures (≥ 50%) were catastrophic (longitudinal fractures).

Four indirect RCs, one polymer-infiltrated ceramic network (PICN), and one direct composite were soaked in water over 270 days, heated, and evaporated water was detected by KFT and TG. Dilatometric (DIL) and TG coupled with Fourier transform infrared spectroscopy (TG-FTIR) measurements were conducted to verify the methodology and to compare with ISO 4049 outcome. Initial water content was measured between 0.19 and 1.65 wt.%, which increased to 0.73-3.12 wt.% upon water sorption over 270 days. The direct RC performed well, indirect RCs showed significant differences, and the PICN performed comparable to indirect RCs. KFT correlated well with ISO, except for one RC. KFT proved slightly more sensitive than TG. DIL offered different linear expansion of high-versus-low-absorbing materials and confirmed the water sorption rate seen by KFT. In contrast to ISO, KFT has the potential to detect initial water content allowing for a precise and kinetic quantification of the water diffusion process.","PeriodicalId":11983,"journal":{"name":"European Journal of Oral Sciences","volume":" ","pages":"e70090"},"PeriodicalIF":2.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13181508/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147467299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The programme and video presentations from EuroPerio 11 (May 2025) were systematically analysed. Among 163 invited presenters, only six (4%) disclosed potential COIs on the conference website, and these disclosures lacked detail. Of 160 analysed presentations, 30.1% declared no COI, 19.6% declared potential COIs, and 48.5% made no disclosure; the median disclosure duration was seven seconds. Observations revealed that COI statements were typically brief, suggesting that disclosure was often treated as a formality rather than a substantive ethical practice. No explicit or publicly accessible criteria for presenter selection were identified on either the conference or federation websites. These findings indicate substantial underreporting of both financial and non-financial COIs, limited enforcement of disclosure practices, and a lack of transparency in presenter selection. Clear, standardised, and verifiable procedures for COI reporting and presenter selection are needed to strengthen scientific integrity and maintain audience trust.","PeriodicalId":11983,"journal":{"name":"European Journal of Oral Sciences","volume":" ","pages":"e70075"},"PeriodicalIF":2.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13181539/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147431761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
