Introduction Recent studies have explored alternative methods to enhance caries prevention and treatment. Luteolin compound has been noted for its antimicrobial properties, while zinc nanoparticles (Zn NPs) are recognized their potent antibacterial effects. This study investigates the synthesis, characterization, efficacy of luteolin-loaded Zn oxide NPs (Luteo-ZnONPs) against cariogenic bacteria. By combining biofilm-targeting capabilities luteolin with properties NPs, we aim explore a novel approach dental management. Methods Luteo-ZnONPs were synthesized characterized using ultraviolet-visible (UV-vis) Fourier transform infrared (FTIR) spectroscopy, confirming successful formation stability. Antimicrobial was assessed through minimum inhibitory concentration (MIC), demonstrating effectiveness bacteria such as

Oral squamous cell carcinoma (OSCC) is a prevalent oral malignancy, which poses significant health risks with high mortality rate. Regulatory T cells (Tregs), characterized by their immunosuppressive capabilities, are intricately linked to OSCC progression and patient outcomes. The metabolic reprogramming of Tregs within the tumor microenvironment (TME) underpins function, key pathways such as tryptophan-kynurenine-aryl hydrocarbon receptor, PI3K-Akt-mTOR nucleotide metabolism significantly contributing suppressive activities. Targeting these offers novel therapeutic approach reduce Treg-mediated immunosuppression enhance anti-tumor responses. This review explores dependencies that sustain Treg function in OSCC, highlighting adaptations glycolysis, fatty acid oxidation, amino signaling pathway enable thrive challenging conditions TME. Additionally, discusses influence microbiome on evaluates potential strategies targeting pathways. Despite promising interventions, challenges selectivity, toxicity, heterogeneity, resistance mechanisms remain. concludes perspectives personalized medicine integrative approaches, emphasizing need for continued research translate findings into effective clinical applications treatment.

Biofilm formation constitutes the primary cause of various chronic infections, such as wound gastrointestinal inflammation and dental caries. While preliminary achievement biofilm inhibition is possible, challenge lies in difficulty eliminating bactericidal effects current drugs that lead to microbiota imbalance. This study, utilizing vitro vivo models caries, aims efficiently inhibit without inducing effects, even against pathogenic bacteria. The tetrahedral framework nucleic acid (tFNA) was employed a delivery vector for small-molecule inhibitor (smI) specifically targeting activity glucosyltransferases C (GtfC). It observed tFNA loaded smI small-groove binding manner, transferring it into Streptococcus mutans, thereby inhibiting GtfC extracellular polymeric substances compromising bacterial survival. Furthermore, smI-loaded demonstrated reduction severity caries adversely affecting oral microbial diversity exhibited desirable topical systemic biosafety. study emphasizes concept 'ecological prevention biofilm', which anticipated advance optimization strategies clinical application DNA nanocarrier-based drug formulations.

Antibacterial peptides (ABPs) have been recognized as promising alternatives to conventional antibiotics due their broad antibacterial spectrum, high activity, and low possibility of inducing bacterial resistance. However, antibiofilm mechanisms not yet reached a consensus. In this study, we investigated the activity short helical peptide G3 against

Abstract Introduction Nanotechnology offers new approaches and endless opportunities for remineralizing tooth decay without being toxic or causing allergies. This study aimed to determine the effect of nanosilver fluoride (NSF) on remineralization potential enamel caries-like lesions compared 5% sodium varnish in permanent teeth. Methods Fifteen teeth (molars premolars) were gathered, cleaned, polished using a scaler. After sectioning mesiodistally removing roots, thirty specimens subjected demineralized solution induce early then assigned randomly into two equal groups. The test materials applied, all pH cycling model 30 days. DIAGNOdent surface roughness investigated, an evaluation Ca P weight% Ca/P ratio calculation was done SEM-EDX analyze at end study. data analyzed independent t-test. Results mean values measurements NSF NaF baseline after demineralization not significantly different ( p > 0.05). treatment, showed higher measurement (11.8 ± 5.80) than (4.7 1.6). group (1.64 0.39) much NSF’s (1.07 0.21). Specimens treated with had statistically significant smoother surfaces < 0.001). (2.9 0.35) (2.2 0.11). difference = 0.012). Conclusion reveals that nano silver is more effective treatment enhancing teeth’s clinical characteristics, particularly terms mineral content roughness, suggesting it could be improved strategy prevent dental caries maintain integrity.
