Assessment of Moringa oleifera thermoreversible gel as a supplement to nonsurgical periodontal therapy in Stage III periodontitis – A randomized controlled clinical study

A natural plant-based gel applied directly into infected gum pockets performed as well as an established antibiotic treatment for advanced gum disease — that is the headline finding from this small but carefully designed clinical trial. Periodontitis is a chronic infection of the tissues supporting the teeth, driven by bacterial biofilms and the body's own inflammatory response. Left untreated, it destroys the bone and connective tissue that hold teeth in place. The standard nonsurgical treatment is scaling and root planing (SRP), a deep-cleaning procedure that removes bacterial deposits from tooth roots. This trial tested whether adding a thermoreversible gel made from 5% Moringa oleifera extract could improve outcomes beyond SRP alone. A thermoreversible gel is liquid at room temperature but solidifies at body temperature, allowing it to sit in the gum pocket and release its active compounds over time. Thirty patients with Stage III periodontitis — a severe classification involving significant attachment loss — were divided into three groups: SRP alone, SRP plus tetracycline antibiotic fibers (a well-established adjunct), and SRP plus the moringa gel. After two months, all groups improved significantly. However, the moringa group showed the largest reduction in nitric oxide, a marker of tissue inflammation, and the greatest increase in periostin, a protein involved in tissue repair and regeneration. These differences were statistically significant compared to the tetracycline group. Total antioxidant capacity improved across all groups, with the moringa group trending higher but not reaching statistical significance. The findings suggest moringa gel may offer a plant-derived, antibiotic-free option for supporting periodontal treatment, though the small sample size means these results need confirmation in larger trials.
