However, due to the complexity of the craniofacial skeleton and differences related to gender, age, and ethnicity, cephalometric analysis can be prone to errors. This multicenter, cross-sectional study aimed to compare cephalometric measurements between skeletal class I and II in German orthodontic patients and analyze the effect of gender/age subgroups. <b>Materials and Methods:</b> In total, 556 German orthodontic patients were included and stratified into skeletal class I (<i>n</i> = 210) and II (<i>n</i> = 346), based on the individualized ANB of Panagiotidis and Witt (Calculated_ANB). Both classes presented a mean age of 13 with a range of 6.6-41 years and 5.4-53 years in classes I and II, respectively. Regarding the gender variations, most participants were females, <i>n</i> = 194 (56%) among class I, and <i>n</i> = 125 (60%) among class II. Cephalometric parameters were compared between classes and among age and gender-specific subgroups, followed by identifying correlations and performing principal component analysis (PCA). <b>Results:</b> Class II patients presented a more considerable sagittal discrepancy between jaw bases than class I cases (Calculated_ANB 2.8° vs. 0.025°), a more horizontal growth pattern (Gonion angle 119° vs. 123°), and compensated inclinations of the incisors in the upper (+ 1/NL 71° vs. 68°) and lower jaw (-1/ML 84° vs. 80°). Correlations were found between sagittal, vertical, and dental cephalometric parameters, which were strongest in adult class II males. Finally, ML-NSL angle, SNPg angle, PFH/AFH ratio, and SNB angle are related to the variations of the first four components. <b>Conclusions:</b> The differences in cephalometric parameters between skeletal class I and II demonstrate certain configurations in vertical, sagittal, and dental parameters, and identifying these marks precisely will enable accurate diagnosis. In addition, the variations concerning gender and age highlight the possible influence of these factors on orthodontic diagnostics and treatment planning. Future studies with equal sample sizes among subgroups must validate these findings. Finally, the PCA results highlighted that the mandible's vertical and sagittal position has a strong influence on the diagnosis of skeletal class I/II, which highlights the importance of identifying the corresponding reference marks.</p>","PeriodicalId":13947,"journal":{"name":"International Journal of Dentistry","volume":"2025 ","pages":"9665260"},"PeriodicalIF":2.2,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12393958/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144953093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional diagnostic methods, including visual examination and bitewing radiographs, are prone to interpretation variability. Artificial intelligence (AI), particularly deep learning (DL), has shown promise in improving diagnostic accuracy. This study evaluates the YOLOv11 model for dental caries detection and segmentation in bitewing radiographs, using the standardized International Caries Classification and Management System (ICCMS) framework. <b>Methods:</b> A dataset of 730 bitewing radiographs, containing 1115 annotated carious lesions, was used for training and validation. Annotation was performed by experienced dentists using the Roboflow platform. To evaluate annotation consistency, a subset of 10 images was independently annotated by both dentists. Agreement was assessed using Intersection over Union (IoU) and Dice similarity coefficient (DSC). The YOLOv11 model was trained for 50 epochs with data augmentation techniques. Performance was assessed using precision (P), recall (R), and mean average precision at 50% IoU (mAP50). <b>Results:</b> The reliability analysis showed strong agreement, with an average interrater IoU of 0.82 and DSC of 0.85, and intrarater IoU of 0.84 and DSC of 0.87 across the 10 images.

Oxidative stress is widely recognized to suppress the Wnt/β-catenin signaling pathway, thereby impairing bone metabolism and homeostasis. However, there are few reports on whether excessive reactive oxygen species (ROS) influence osteogenic differentiation of stem cells via the noncanonical Wnt/calmodulin-dependent protein kinase II (CaMK II) pathway. An investigation of the mechanism by which ROS/CaMK II/β-catenin signaling axis influences the osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) on titanium surfaces is being carried out in this investigation. <b>Materials and Methods:</b> In this study, titanium plates were specially treated to simulate implant surfaces. An osteogenic medium containing HG was used to cultivate BMSCs on titanium surfaces. The effects of excessive ROS induced by HG on the osteogenic differentiation of BMSCs, as well as on the expression of β-catenin and CaMK II, were examined using methods such as alkaline phosphatase (ALP) activity assay, quantitative real-time PCR (qRT-PCR), and immunofluorescence staining. Additionally, the effects of the Wnt/β-catenin and Wnt/CaMK II pathways on the osteogenesis of BMSCs on the titanium surface were observed by separately adding activators or inhibitors of β-catenin and CaMK II. <b>Results:</b> Excessive ROS induced by HG inhibited osteogenic differentiation. In a HG environment, β-catenin expression decreased, while CaMK II expression increased. Moreover, we observed that activation of the Wnt/β-catenin pathway promoted osteogenesis, whereas activation of the Wnt/CaMK II pathway inhibited it. <b>Conclusions:</b> In summary, BMSC osteogenesis on titanium surfaces is suppressed by HG-induced oxidative stress via the ROS/CaMK II/β-catenin signaling axis, which may subsequently impair implant osseointegration.</p>","PeriodicalId":13947,"journal":{"name":"International Journal of Dentistry","volume":"2025 ","pages":"5566776"},"PeriodicalIF":2.2,"publicationDate":"2025-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12373472/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144953252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study employs proteomic analysis to identify salivary biomarkers associated with Pd and to evaluate the impact of nonsurgical periodontal therapy (NSPT) on the salivary proteome. <b>Methods:</b> Comparative proteomic analysis was performed on saliva samples from periodontally healthy individuals (G1 group) and patients with advanced Pd (G2 group).
