Simvastatin, traditionally used for managing hypercholesterolemia, has recently emerged as a promising bioactive agent in dentistry due to its diverse biological actions. Growing scientific evidence indicates its potential role in enhancing hard tissue regeneration, modulating inflammatory responses, and exerting antimicrobial effects within the oral environment. By influencing molecular pathways involved in bone metabolism and cellular differentiation, simvastatin contributes to improved tissue repair and mineralized tissue formation.

Experimental and clinical studies suggest beneficial outcomes in periodontal therapy, endodontic management, implant healing, and osseous defect regeneration when simvastatin is applied locally or systemically. Its adjunctive use has been associated with improved healing responses and enhanced clinical parameters in various dental conditions.

Despite encouraging findings, differences in study protocols, concentrations, and delivery systems necessitate further well-designed, long-term clinical trials to establish standardized guidelines.  Simvastatin holds significant potential as an adjunctive therapeutic agent in modern regenerative dentistry.
