Interactions Between Silica And Titanium Nanoparticles And Oral And Gastrointestinal Epithelia: Consequences For Inflammatory Diseases And Cancer, Cassio Luiz Coutinho Almeida-Da-Silva, Leticia Ferreira Cabido, Wei Chun Chin, Ge Wang, David M. Ojcius, Changqing Li

All Dugoni School of Dentistry Faculty Articles

Engineered nanoparticles (NPs) composed of elements such as silica and titanium, smaller than 100 nm in diameter and their aggregates, are found in consumer products such as cosmetics, food, antimicrobials and drug delivery systems, and oral health products such as toothpaste and dental materials. They may also interact accidently with epithelial tissues in the intestines and oral cavity, where they can aggregate into larger particles and induce inflammation through pathways such as inflammasome activation. Persistent inflammation can lead to precancerous lesions. Both the particles and lesions are difficult to detect in biopsies, especially in clinical settings that screen large numbers …
