生物活性
描述 Chlorhexidine Dihydrochloride (CHX) has proven antimicrobial activity, excellent substantivity, low surface tension, and low cytotoxicity and genotoxicity that depend on the dose and exposed area[3]. CHX-IBU (chlorhexidine dihydrochloride - ibuprofen) loaded ISFI (in-situ forming implants) could be efficient as adjuvant to periodontal therapy for the control of infection and inflammation[4]. Moreover, CHX decreased in a concentration-dependend manner the number of attached gingival epithelial cells and PDL (periodontal ligament) fibroblasts. Rinsing with CHX may prevent or at least retard bacterial colonization on membrane exposed to the oral activity[5].
