Inflammation Gum Clinical Trial
Official title:
Efficacy of Quercetin Nanoemulgel as Adjunct Local Delivery Drug in Non-surgical Treatment of Periodontitis
Periodontitis is an immune-inflammatory disease affecting the supporting structures of the teeth. It is a disease of multifactorial etiology, with microbial, genetic, environmental and host factors involved, with the release of oxygen-free radicals by the inflammatory cells. Quercetin, have shown potential antimicrobial activity, lowering of inflammatory markers, cholesterol reduction and inhibiting bone loss. However, this data has largely been obtained from in vitro and animal studies, but data from human studies are limited.
Quercetin has been found to decrease the extracellular matrix degradation, promote wound healing when tested in gingival fibroblasts, and showed excellent antibacterial properties. It also possesses antioxidant effect which can be explored to restrict the inflammation in periodontitis. Despite the beneficial effects of Quercetin, its poor aqueous solubility and poor bioavailability result in limited absorption, so scientists have worked on improving the bioavailability of Quercetin using various approaches, such as nanosuspension , self-nano emulsifying systems , microemulsion , solid lipid nanoparticles and cyclodextrin complexes. The combination of oils and emulsifiers enhances the absorption of Quercetin. Hence, nanoemulsion could be a suitable drug delivery vehicle for the loading of Quercetin. Nanoemulsions are more beneficial than microemulsions, as they have high kinetic stability and a smaller droplet size. Therefore, the present study will investigate the efficacy of nanoemulgel of quercetin as adjunct to conventional therapy in treatment of periodontitis. ;
