Forty implants were randomly assigned to one of four groups: oxidized implant surfaces (OIS, n = 10), turned/machined implant surfaces (TIS, n = 10), OIS + GBR (n = 10), and TIS + GBR (n = 10). After 3 months, the dogs were euthanized, and the blocks containing the implants and adjacent bone were processed for non-decalcified histological analysis. Statistical analysis was performed using two-way ANOVA and the Pearson correlation (p = 0.05). The results showed that GBR significantly influenced both the vertical (height) and horizontal (thickness) dimensions of the newly formed bone (p < 0.001). Strong positive correlations were observed between the thickness and height of newly formed bone at the base of the defect, as well as between the thickness of the bone at the base of the defect and the thickness of newly formed bone in the central region of the defect. No significant correlations were found between implant surface type and bone formation. Bone regeneration occurred in both the vertical and horizontal directions, with greater bone growth in GBR-treated groups, irrespective of implant surface type (oxidized or turned).","PeriodicalId":9240,"journal":{"name":"Brazilian oral research","volume":"39 ","pages":"e079"},"PeriodicalIF":1.3,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12419196/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145032861","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 results were analyzed by descriptive statistics and analysis of variance. The flexural strength and the modulus of elasticity analyses were performed using bar-shaped test specimens of three commercial resin composites with and without barriers, and the tests were subjected to a statistical normality test.

The recovered microbial load differed significantly between T1 and T2 (p < 0.05). The results of the flexural strength and modulus of elasticity analyses showed no significant differences with or without a barrier for any of the different colors of resin, polymerization time, or the three resins. Under the present experimental conditions, 70% ethanol significantly reduced the levels of microbial contamination, but it did not guarantee the inactivation of all microbial cells.

This study aimed to evaluate the diagnostic accuracy of smartphone photography for detecting active caries in orthodontic patients. The sample comprised 100 individuals of both sexes, aged 11 to 46 years, who were undergoing fixed orthodontic treatment. Following professional tooth cleaning and drying, patients underwent a visual-tactile clinical examination for caries detection, which served as the gold standard. Digital photographs were then taken using a smartphone camera in five views: frontal, right and left lateral, and upper and lower occlusal. The diagnostic parameters-sensitivity, specificity, accuracy, positive predictive value (PV+), and negative predictive value (PV-)-were calculated for the photographic method relative to the clinical examination. The prevalence of active caries in the sample was 74%. The smartphone photographs correctly identified 66 of the 74 individuals with active caries according to the gold standard. However, only 4 of the 26 sound patients were correctly identified. These findings correspond to the following diagnostic parameters: sensitivity, 89%; specificity, 15%; accuracy, 70%; PV+, 75%; and PV-, 33%.

Data analysis involved descriptive statistics, chi-square test, and bivariate and multivariate Poisson regression analyses (p < 0.05; 95%CI). The prevalence of recurrent tooth injuries in the deciduous dentition was 17.2% (n = 89). Children aged between four and six years (PR = 1.917; 95%CI: 1.055-3.484; p = 0.033), those with inadequate lip protection (PR = 1.790; 95%CI: 1.085-2.953; p = 0.023), those with uncomplicated crown and crown-root fractures (PR = 1.856; 95%CI: 1.224-2.816; p = 0.004), and those with complicated crown and crown-root fractures (PR = 1.818; 95%CI: 1.021-3.239; p = 0.042) had a greater frequency of repeated tooth injuries compared to children without these characteristics. In the present study, older age, inadequate lip coverage, and the occurrence of complicated and uncomplicated crown and crown-root fractures were associated with repeated injuries in the deciduous teeth.","PeriodicalId":9240,"journal":{"name":"Brazilian oral research","volume":"39 ","pages":"e093"},"PeriodicalIF":1.3,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12419183/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145032781","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}

Enamel and dentin cavities in molars (n = 10) were restored with a) bulk-fill resin composite (Tetric N-Flow Bulk Fill, BF) with the application of a universal adhesive (Tetric N-Bond Universal) and b) alkasite restorative material (Cention N, CN) with and without the application of a universal adhesive. After 24 h (baseline), surface roughness and hardness of the restorative material and dental tissues were assessed at 100 μm from the tooth/restoration interface. The specimens were subjected to degradation in whole saliva for 7 days (combined with the application of 20% sucrose 10x/day). Ra and VHN were then reassessed. The data were analyzed by ANOVA and Tukey's test (α = 5%). BF exhibited a significantly lower Ra than CN. Ra increased significantly after degradation in saliva when compared to baseline values. Enamel hardness was higher for BF restorations. No differences in enamel hardness were observed for alkasite restorations with and without adhesive application. For dentin hardness, significantly lower values were found in alkasite restorations with previous application of an adhesive system. It can be concluded that BF had a smoother surface than CN before and after degradation. Immersion in saliva reduced the hardness of both restorative materials, enamel, and dentin adjacent to the restoration.","PeriodicalId":9240,"journal":{"name":"Brazilian oral research","volume":"39 ","pages":"e091"},"PeriodicalIF":1.3,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12419195/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145032910","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}
