The dextran-mediated biofilm affinity of the nano-toothbrush induced localized oxidative stress under ultrasound irradiation, effectively disrupting biofilms and inhibiting pathogenic bacteria. This efficacy was evidenced by the removal of ex vivo biofilms from periodontitis patients. Importantly, the selective action of the nano-toothbrush minimized the damage to mouse fibroblasts and human immortalized oral epithelial cells, affirming its biosafety. In vivo studies showed that the nano-toothbrush significantly inhibited the cell viability of <jats:italic>Porphyromonas gingivalis</jats:italic> , effectively suppressed alveolar bone resorption, and alleviated inflammatory responses in a rat periodontitis model while concurrently preserving the diversity of the oral microbiome.

While the immune system has been found to regulate this process, previous studies mostly focused on the static molecular changes in conventional immune cell sets. A recent study used single-cell RNA sequencing (scRNA-seq) to analyze macrophages under orthodontic tooth movement (OTM), introducing new subclusters and functions. However, changes in other immune cells and their interactions with surrounding stromal cells are yet unclarified. Therefore, we performed scRNA-seq in mice, aiming to describe a more comprehensive immune landscape during OTM, while further exploring the dynamic changes, functions, and cellular interactions of immune cells at a higher resolution. We first confirmed the dynamic activation of osteoclasts, osteoblasts, and immune cells at various time points. The scRNA-seq analysis identified 7 cell lineages and 18 major cell types, with immune cells forming the largest proportion. Monocytic cells, granulocytes, and lymphocytes were selected for individual reclustering, followed by analysis of specific gene expression, functional enrichment, and distribution changes during OTM. Pseudotime analysis was applied to monocytic cells and granulocytes. We identified 4 developmental pathways in monocytic cells toward dendritic cells, different subsets of macrophages, and osteoclasts. Monocytic cells tended to be more differentiated during OTM. Meanwhile, in granulocytes, neutrophil subclusters were all highly differentiated. Additionally, we assessed the cellular interactions during OTM, revealing enhanced signaling from macrophages toward osteoclasts, especially in Ccl, Tnf, and Spp1 pathways. We identified that the <jats:italic> C3ar1 <jats:sup>+</jats:sup> </jats:italic> macrophage subcluster expressed these cytokines at a high level and was enriched in positive regulation of the mitogen-activated protein kinase cascade, indicating its positive regulation toward osteoclast activity.

Saliva contamination can form a nanoscale bacteria-contained adsorption film with high hydration on demineralized dentin matrix (DDM), worsening the insufficient adhesive infiltration into the DDM and causing bacteria load. The resultant bacteria-loaded hybrid layer with more defects aggravates the durability issue of dentin bonding that affects the oral health of billions of people worldwide. To address the issue of saliva contamination, a robust polycation assembly-assisted bonding strategy was developed based on the electrostatic adsorption of bactericidal polycations on the natural template of a 3-dimensional, porous, negatively charged DDM as well as the contaminated DDM to form a stable electrostatic complex via electrostatic adsorption. Both residual bacteria in the biofilm and bacteria from saliva were killed, and the hydrated DDM was dehydrated, causing the release of interface-confined water regardless of the presence of contamination, which greatly improved adhesive infiltration. More interesting, due to the charge reversal caused by polycation adsorption, the polycation/DDM complex actively adsorbed negatively charged saliva proteins continuously and formed a stable polycation/DDM/saliva protein complex, actively erasing the adverse effect of saliva contamination on dentin bonding. This is the first successful construction of a persistently antibacterial and defect-low hybrid layer under saliva contamination.","PeriodicalId":15596,"journal":{"name":"Journal of Dental Research","volume":"653 1","pages":"220345251334377"},"PeriodicalIF":7.6,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144488288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluated the effect of calcium silicate particules (CaSi) particles applied as a pretreatment to acid-etched dentin surfaces and/or added (5% by mass) to the bonding resin of a commercial 3-step adhesive system. The mechanical properties of the adhesive layer, hybrid layer, and underlying dentin were measured by nanoindentation after 24 h and 6 and 12 mo of storage in simulated body fluid (SBF) and observed by scanning electron microscopy. Calcium and phosphorus were quantified by energy-dispersive x-ray spectroscopy. Enzymatic activity was estimated by in situ zymography and hydroxyproline assay after 24 h and 12 mo. Microtensile bond strength was determined after 24 h and 12 mo in SBF. Data were analyzed by repeated measures analysis of variance and Tukey test (alpha, 5%). CaSi used as a pretreatment or added to the bonding resin reduced the mechanical properties of the adhesive layer. Notwithstanding, only where CaSi was present did groups show significant increases in mechanical properties for the hybrid layer and the underlying dentin after prolonged storage, suggesting the occurrence of apatite precipitation. This result corroborates the higher calcium content disclosed by energy-dispersive x-ray spectroscopy. Also, CaSi-containing pretreatment and/or the addition of CaSi to the bonding resin inhibited metalloprotease activity, as confirmed in situ and by the reduced hydroxyproline release. However, microtensile bond strength reductions after 12-mo storage in SBF were observed in all groups. The findings suggest that CaSi, whether applied as a pretreatment, added to the bonding resin, or both, promoted mineral precipitation and inhibited enzymatic activity at the bonded interface.","PeriodicalId":15596,"journal":{"name":"Journal of Dental Research","volume":"55 1","pages":"220345251336125"},"PeriodicalIF":7.6,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144488269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We retrospectively collected panoramic radiography (PR) images and medical records of 366 patients with ONJ to develop the ONJ-TS system. In the ONJ-TS system, the core Qwen2-VL was fine-tuned for natural language question answering on ONJ treatment. To support the primary functionality of the Qwen2-VL, we trained the SwinTransformer and the U-Net to identify ONJ cases and segment the ONJ regions in the PR images, respectively.

The incidence of HPV-associated oropharyngeal cancer is increasing. Yet, population screening for oral HPV infection is not recommended by the Food and Drug Administration due to the low prevalence and lack of a universally accepted screening strategy or tool. The study aims to evaluate the link between cervical and oral HPV infection in women and identify high-risk groups. The protocol was registered on PROSPERO (CRD42023477695). The systematic search was performed in 3 databases (PubMed, EMBASE, and CENTRAL) on January 3, 2025. Forty-one analytical observational studies reporting on oral HPV status in women with and without cervical HPV positivity were included. Effect sizes, including proportions and odds ratios with 95% confidence intervals (CIs), were analyzed using a random-effects model. Location, population characteristics, and sampling methods were used to perform the subgroup analyses. The meta-analysis revealed an odds ratio of 2.22 (CI: 1.52-3.25) for oral HPV in women with cervical HPV positivity compared with those without it. The prevalence of oral HPV was significantly higher in cervical HPV-positive women (13%, CI: 8%-20%) than in HPV-negative women (4%, CI: 2%-7%). In addition, the prevalence of oral HPV was even higher in cervical HPV-positive women with positive cytology (17%, CI: 6%-39%). Risk-of-bias assessment indicated low risk among all studies using Quality in Prognosis Studies and moderate to low risk among studies assessed with the Joanna Briggs Institute Prevalence Critical Appraisal Tool. Our findings support the association between cervical HPV positivity and elevated risk for oral HPV infection. Moreover, the highest prevalence of oral HPV carriage was observed in women with positive cytology. As 1 in 8 women with cervical HPV carries oral HPV, screening should be considered for this at-risk population.","PeriodicalId":15596,"journal":{"name":"Journal of Dental Research","volume":"25 1","pages":"220345251337071"},"PeriodicalIF":7.6,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144370369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This complexity presents challenges in balancing multiple considerations comprehensively and automating the entire workflow efficiently. This study aims to achieve intelligent virtual dental implant placement through a 3-dimensional (3D) segmentation strategy. Focusing on the missing mandibular first molars, we developed a segmentation module based on nnU-Net to generate the virtual implant from the edentulous region of CBCT and employed an approximation module for mathematical optimization. The generated virtual implant was integrated with the original CBCT to meet clinical requirements. A total of 190 CBCT scans from 4 centers were collected for model development and testing. This tool segmented the virtual implant with a surface Dice coefficient (sDice) of 0.903 and 0.884 on internal and external testing sets.

The rendering quality and resource usage were compared with representative NVS methods. In addition, the linear measurement trueness of extracted craniofacial meshes was evaluated against a commercial facial scanner and 3 smartphone facial scanning apps, while teeth meshes were assessed against 2 intraoral scanners and a desktop scanner. GS-based representation demonstrated superior rendering quality, achieving the highest visual quality, fastest rendering speed, and lowest resource usage. The craniofacial measurements showed similar trueness to commercial facial scanners. The dental measurements had larger deviations than intraoral and desktop scanners did, although all deviations remained within clinically acceptable limits. The GS-based representation shows great potential for developing a convenient and cost-effective method of capturing dental scenes, offering a balance between color fidelity and trueness suitable for clinical applications.","PeriodicalId":15596,"journal":{"name":"Journal of Dental Research","volume":"6 1","pages":""},"PeriodicalIF":7.6,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144278345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We recruited 76 periodontally healthy, caries-free individuals aged 10 to 17 y into 3 groups: MetS (29), metabolically healthy obesity (MHO) (30), and normal-weight healthy (NWH) controls (17). Unstimulated saliva was collected. Bacterial DNA was isolated, V3–V4 regions amplified, and 16S sequencing performed on the Illumina MiSeq platform. Sequences were annotated against the HOMD database. Multiplex assays quantified adipokines and cytokines, with significance determined by Tukey honestly significant difference. Gas chromatography/mass spectrometry identified metabolite peaks that were annotated against the Small Molecule Pathway Database, with enrichment analysis determining significance. Integrated multiomics analysis was performed using multiblock sparse partial least squares regression discriminant analysis. The MHO and MetS groups demonstrated lower abundances of <jats:italic>Streptococcus</jats:italic> , <jats:italic>Actinomyces</jats:italic> , and <jats:italic>Schaalia</jats:italic> and higher levels of <jats:italic>Aggregatibacter</jats:italic> , <jats:italic>Campylobacter</jats:italic> , <jats:italic>Alloprevotella</jats:italic> , <jats:italic>Prevotella</jats:italic> , <jats:italic>Leptotrichia</jats:italic> , and <jats:italic>Porphyromonas</jats:italic> compared with NWH, despite similar clinical oral status in all cohorts. MetS and MHO also had increased leptin, tumor necrosis factor–α, interleukin (IL)–1β, and IL-15 and decreased adiponectin levels versus NWH. Disease-associated metabolites, including glutamate, cholesterol, isoleucine, tyrosine, phenylalanine, serine, and indoleacetic acid, were significantly enriched in the MetS and MHO groups. Integrated multiomic analysis identified key correlations in the saliva of subjects with metabolic health or disease. Decreases in health-associated species and increases in proinflammatory cytokines and disease-associated metabolites in the saliva of MetS and obese adolescents with clinical oral health indicate an “at-risk” environment, potentially explaining their elevated risk for oral diseases. Increased salivary leptin and decreased adiponectin levels highlight the potential of saliva as a noninvasive biomarker source for childhood MetS.","PeriodicalId":15596,"journal":{"name":"Journal of Dental Research","volume":"52 1","pages":""},"PeriodicalIF":7.6,"publicationDate":"2025-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144188836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
