Does Titanium Dioxide Help With In dental and oral health applications, TiO₂ nanoparticle...?
Weak EvidenceEvidence Summary
In dental and oral health applications, TiO₂ nanoparticles incorporated into orthodontic appliances demonstrated significant antibacterial activity, reducing bacterial colony counts after 4-6 months of use (PMID 38178135). When used as a photocatalyst in hydrogen peroxide bleaching gels, nitrogen-doped TiO₂ enabled effective tooth whitening with reduced sensitivity compared to conventional methods (PMID 40645258). In vitro studies suggest antiviral activity against HSV-1 (PMID 41904822) and antibacterial/anticancer properties in green-synthesized nanoparticle formulations (PMID 41740346), though these findings are preclinical only.
