Evaluation of the Efficacy of a Neem Extract-Based Herbal Ointment, Herbal Antioxidant, and Propolis on Oxidative Stress Related to Oral Ulcers: An Interventional Animal Study.

Unlabelled: Traumatic oral ulcers are one of the most commonly encountered oral ulcers. Their healing may be delayed due to factors like the presence of opportunistic infectious microbes in the oral cavity, secondary trauma from sharp edges of teeth, and the systemic condition of the patient.

Aim: To compare the efficacy of a newly developed neem extract containing herbal ointments (propolis and  in enhancing the wound contraction of traumatic oral ulcers and to determine the relationship between oxidative stress and oral ulcers.

Method: Ulcers were inflicted by trauma in the mouths of experimental rabbits using a 5 mm punch biopsy device. Forty-eight animals were randomly put into six groups (n = 12). Group 1 was the control group that did not receive any intervention; Group 2 had a systemic treatment of extract; Group 3 received a topical application of propolis; Group 4 had a topical application of a neem extract-based herbal ointment; Group 5 was administered a combination of and propolis; and Group 6 had a combination of a neem-based herbal ointment and . Oxidative stress levels were calculated by measuring superoxide dismutases and malondialdehyde levels in the blood on days 0, one, seven, and 14. Wound contraction scores of ulcers were also assessed on days seven and 14.

Results: Significantly higher wound contraction scores were seen in groups treated with herbal ointment in comparison to groups treated without herbal ointment. Oxidative stress levels increased in all groups after the infliction of ulcers (day one) and then declined as the ulcers healed, reaching near-normal levels on day 14. Groups containing  showed a significant reduction in oxidative stress in comparison to groups without . A p-value of <0.05 was considered significant.

Conclusion: A combined formulation of herbal ointment and  proved to be the most efficacious in enhancing wound contraction of oral ulcers along with significantly reducing oxidative stress in experimental rabbits.
