Gingivitis is a reversible, plaque-induced inflammatory disease of gingival tissues and represents the initial stage of periodontal disease. It is primarily induced by dental plaque biofilm, which harbours pathogenic microorganisms that trigger an inflammatory response in the gingival tissues. The clinical features of gingivitis include redness, swelling and bleeding on probing. If left untreated, gingivitis can progress to periodontitis, leading to irreversible loss of supporting structures of the teeth and eventual tooth loss. Conventional management of gingivitis includes mechanical plaque control through toothbrushing, flossing, using interdental aids, and professional scaling. In addition, chemical agents such as chlorhexidine mouthwash are often prescribed as adjuncts for their antibacterial and plaque-inhibitory properties. However, long-term use of synthetic agents is associated with undesirable side effects, including tooth staining, altered taste sensation, and mucosal irritation. These limitations have encouraged the search for safer, natural alternatives that are well-tolerated, effective, and easily available. Herbal medicine has gained increasing attention in dentistry due to its antimicrobial, antioxidant, and anti-inflammatory properties. Among these, Cinnamomum (cinnamon) and Aloe vera stand out as promising agents. Cinnamomum contains bioactive compounds such as cinnamaldehyde and eugenol, which exhibit strong antibacterial, antifungal, and anti-inflammatory effects. These compounds may help in reducing plaque accumulation and controlling gingival inflammation. Aloe vera, on the other hand, has been traditionally used for wound healing and has demonstrated antimicrobial, anti-inflammatory, and soothing effects in various oral conditions. Its gel form is biocompatible, easy to apply, and provides a protective barrier on gingival tissues. Despite their potential benefits, very few clinical studies have directly compared the efficacy of Cinnamomum gel and Aloe vera gel in the management of gingivitis. Understanding their comparative effectiveness will provide valuable insights into evidence-based use of herbal products in dentistry. Hence, the present randomized clinical trial is designed to evaluate and compare the anti-inflammatory and anti-plaque effects of Cinnamomum gel and Aloe vera gel in patients with gingivitis.

This study aims to determine whether these natural agents can serve as safe, effective alternatives or adjuncts to conventional gingivitis therapy.
