Effects of Chlorhexidine on Human Gingival Fibroblasts

Sponsor: IRCCS San Raffaele

Summary

This prospective in vitro study aims to evaluate the effects of two chlorhexidine-based mouthwash formulations on the survival and function of human gingival fibroblasts (hGFs). Gingival fibroblasts obtained from discarded gingival tissue collected during routine dental procedures will be cultured and exposed to different concentrations of a conventional 0.2% chlorhexidine mouthwash and a 0.2% chlorhexidine mouthwash supplemented with N-acetylcysteine (NAC) and hyaluronic acid (HA). Cell viability, apoptosis, migration, and gene expression will be assessed at multiple time points using Trypan Blue exclusion assay, fluorescence-activated cell sorting (FACS), scratch assay, and quantitative real-time PCR. The study is designed to investigate the concentration-dependent effects of chlorhexidine on fibroblast viability and wound-healing-related functions and to determine whether the addition of NAC and HA may improve the biological compatibility of chlorhexidine-based formulations.
