Triple Antibiotic Gel in The Management of Periodontal Disease: A Narrative Review

Abstract Periodontal disease is a chronic inflammatory condition caused by bacterial biofilms, leading to progressive destruction of the tooth-supporting structures. Conventional treatments such as scaling and root planing (SRP) are effective but may not completely eradicate pathogenic bacteria, necessitating adjunctive antimicrobial therapies. The use of locally delivered antibiotic gels has emerged as a promising approach to enhance periodontal healing. Triple antibiotic gel formulations, commonly consisting of metronidazole, ciprofloxacin, and minocycline, offer targeted antimicrobial action, reducing bacterial load and inflammation within periodontal pockets. Localized drug delivery minimizes systemic side effects while maintaining therapeutic concentrations at the site of infection. Despite these benefits, concerns remain regarding antibiotic resistance, potential allergic reactions, and long-term efficacy. This review discusses the role of triple antibiotic gel in periodontal therapy, its clinical effectiveness, advantages, limitations, and future research directions. Optimizing antibiotic formulations and developing strategies to mitigate resistance will be essential for ensuring the long-term success of this therapeutic approach in periodontal disease management.
