Glass infiltration was performed on pre-sintered specimens followed by final sintering, and half of the specimens from each group underwent hydrothermal aging (134°C, 2.2 bar, 20 h). Microstructure and phase composition were assessed by scanning electron microscopy and x-ray diffraction. Mechanical performance was evaluated using step-stress accelerated life testing, with Weibull statistics, reliability analysis, and inverse power-law modeling. Glass-graded specimens demonstrated higher reliability and characteristic strength (≈330 MPa increase) with similar Weibull modulus compared to controls. The inverse power-law parameter α0 was higher for the glass-graded group, indicating extended fatigue life, whereas comparable α1 values suggested similar life–stress relationships. Hydrothermal aging did not significantly affect mechanical performance, although phase transformation occurred in the control group. Fractography revealed surface-initiated failures in controls and interface-related crack initiation in glass-graded specimens. Graded glass infiltration improved the fatigue reliability and characteristic strength without compromising hydrothermal stability of 4Y-PSZ. These results suggest that glass-graded 4Y-PSZ may expand the clinical applicability of translucent zirconia for long-span (≥4-unit) prosthetic reconstructions.","PeriodicalId":11983,"journal":{"name":"European Journal of Oral Sciences","volume":"134 5","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/eos.70101","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147812737","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}

Cross-sectional analyses using data from the 2019 Brazilian National School Health Survey were performed with stata 18.5, applying survey weights. The outcome was dental service use in the previous year, and the exposure was lifetime self-reported sexual assault. A total of 124,106 adolescents were included; 50.4% were female and 66.3% aged 13–15-yr. Overall, 66.7% reported dental visits in the previous year, 18.6% reported dental pain, and 6.2% reported sexual abuse. Adolescents with a history of sexual assault showed lower prevalence of dental service use compared with their non-abused peers (prevalence ratio [PR] = 0.96; 95% confidence interval [CI]: 0.92–1.00), particularly among girls (PR = 0.94; 95% CI: 0.89–0.98). Dental pain was associated with a modest increase in dental service utilization across all groups, with no evidence of effect modification. These findings suggest that sexual abuse is linked to reduced engagement with dental services during adolescence, especially among females, although the magnitude of this association is modest. The results emphasize the importance of trauma-informed and intersectoral strategies to improve access to oral healthcare for vulnerable populations.","PeriodicalId":11983,"journal":{"name":"European Journal of Oral Sciences","volume":"134 5","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/eos.70111","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148136987","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}

Disc-shaped specimens were fabricated from a provisional (Prov) and long-term (Crown) 3D-printable resin composites using a digital light processing printer. Post-curing protocols included exposure to 405 nm-based light sources (Anycubic for 30 or 60 min in the standard mode or Procure 1) and one 385 nm-based light source (Procure 2 with distinct protocols). Color parameters (L*, a*, b*) were measured at baseline, after 14 and 21 d of dry storage, and after 7 d of water immersion. Post-curing protocol, material, and storage condition significantly influenced color stability. High-irradiance protocols resulted in the highest color change values, exceeding the clinical acceptability threshold (ΔE00 > 1.8). Water immersion induced a significant whitening effect and increased total color change in all groups. The long-term resin demonstrated superior color stability compared to the provisional one across all post-curing protocols. The choice of post-curing protocol is critical for aesthetic performance, as high-irradiance parameters, while potentially beneficial for mechanical properties, can compromise chromatic stability, particularly in materials with low filler content.","PeriodicalId":11983,"journal":{"name":"European Journal of Oral Sciences","volume":"134 5","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/eos.70106","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147940713","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}

Human dental pulp cells were used for in vitro evaluation of cytocompatibility, cell migration and cell–material interactions. Odontogenic differentiation was assessed using a 3D culture model designed to simulate the clinical environment. Pulp capping was performed in vivo on rat maxillary molars, and reparative dentin formation and pulpal inflammatory responses were evaluated using micro-computed tomography (µCT) and histological analyses. In vitro, all investigated materials exhibited comparable cytocompatibility, cell migratory behaviour and odontogenic marker expression, with no significant differences among study groups. The µCT analysis demonstrated significantly greater reparative dentin formation in all experimental groups compared with the control, with Biodentine producing a higher dentin volume than EndocemMTA Premixed. Histological evaluation revealed no significant differences among the experimental groups with respect to pulpal inflammation or dentin bridge continuity. These findings suggest that the incorporation of DMSO into premixed formulations would not adversely affect cytocompatibility or pulp healing. Moreover, the 3D model used in this study might serve as a clinically relevant platform for evaluating pulp–material interactions.","PeriodicalId":11983,"journal":{"name":"European Journal of Oral Sciences","volume":"134 5","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147835131","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}

Data were analyzed using aligned rank transform anova (α < 0.05). CA5n had no impact on the bond strength of Multipurpose at either time point, irrespective of placement. Universal with 1% CA5n exhibited significantly higher 24 h µTBS than all other groups, but this advantage declined after 6 months. Mixed and adhesive failures increased over time, with the highest adhesive failure in Universal 1% at 6 months.
