Catechins, a class of polyphenolic compounds primarily found in green tea, have garnered scientific interest for their potential benefits in oral surgery and oral health. Several in vitro and in vivo studies have demonstrated that catechins, especially epigallocatechin gallate (EGCG), possess strong antimicrobial, anti-inflammatory, and antioxidant properties. In the context of oral surgery, these properties translate to potential benefits such as reducing post-surgical inflammation, minimizing bacterial infections, and promoting wound healing.

Clinical research has shown that catechins can inhibit the growth of common oral pathogens like Porphyromonas gingivalis and Streptococcus mutans, which are implicated in periodontal disease and post-operative infections. Additionally, studies have reported that topical or oral application of catechin-rich green tea extracts can decrease bleeding and accelerate tissue regeneration following dental procedures. Some trials have also observed reduced postoperative pain and swelling in patients who used catechin-containing mouthwashes after oral surgery.

However, while there is a growing body of evidence supporting the adjunctive use of catechins in oral surgery, most studies are preliminary, with limited large-scale, randomized clinical trials. As such, the overall evidence base is moderate (rated 3/5), suggesting catechins may be beneficial but should complement, not replace, standard oral surgical care. Further robust clinical trials are needed to clarify optimal dosing, formulation, and long-term safety.
