Efficacy of Locally Delivered Azadirachta Indica (Neem) Extract as an Adjunct to Non-Surgical Periodontal Management

Total number of thirty-two (32) periodontitis patients including both males and females will be included in the study.

To assess the effect of neem gel on the clinical parameters of patients with localized periodontitis t-test or an equivalent non-parametric test will be used for comparison of Intervention group (neem extract gel) and Control group (non-surgical periodontal debridement). At first preoperative periapical radiographs will be taken for assessment of bone level. The patients will receive full mouth one stage debridement using ultrasonic scalers, manual scalers and curettes with oral hygiene instructions and education.

Baseline assessment will be done following phase I therapy by 2 weeks by full mouth periodontal charting and samples from gingival crevicular fluid will be taken using a sterile perio-paper inserted into the deepest periodontal pocket with horizontal bone loss. AzadirachtaIndica Extract Gel will be applied in the deepest pocket by syringe with blunted tip gently and removed slowly in order not to harm the tissue for group 1 patients after phase 1 therapy by two weeks. Follow up of the patients will be done after 3 months after phase I therapy with evaluation of the clinical parameters. The patients will be instructed to brush their teeth 3 times per day during the treatment period using a soft tooth brush together with regular flossing of teeth. A brochure containing written oral hygiene instructions will be given to the patients.

The clinical parameters will be measured two times during the study, the first time at the baseline after two weeks of full mouth debridement and the second time is after baseline by 3 months.

GCF sampling will be done just before neem gel application. Mean values of each parameter will be calculated per patient and per group as well as parameters at the deepest pocket site.
