Punica granatum peel extract as adjunct irrigation to nonsurgical treatment of chronic gingivitis.

Pomegranate is one of the most universally studied medicinal plants for its ethnomedical history, with several studies presenting the positive outcome of its use or its extracts in managing inflammation. The objective of the present trial was to investigate the efficiency of the traditionally used 5% of pomegranate peel extract in treating gingival inflammation. Herein, 34 chronic gingivitis patients were randomized in a 1:1 ratio for four weeks in a controlled, double-blind clinical trial to evaluate the effect of the adjunctive use of a pulsating jet irrigator containing 5% pomegranate peel extract solution to nonsurgical periodontal therapy against a placebo in managing these patients' condition. No adverse reactions had been reported, and within the limits of this study, it may be concluded that pomegranate peel extract can serve as a promising alternative in managing chronic gingivitis. This trial is registered on the German clinical trials register (DRKS-ID: DRKS00010602).
