Aim \& objectives of the Study:
The aim of this randomized controlled clinical and biochemical trial is to assess the efficacy of locally applied Melaleuca Alternifolia (tea tree oil) gel as a supplement to non-surgical periodontal debridement in the treatment of patients with localized periodontitis.
Primary objectives:
* Assess the effectiveness of tea tree oil gel in the management of periodontitis using clinical parameters.
* Evaluate Patients' satisfaction using the patient satisfaction questionnaire.
Secondary objective:
• Determine the impact of tea tree oil gel on the level of Tumor Necrosis Factor (TNF-α) in the gingival crevicular fluid.
Treatment protocol and intervention:
* Preoperative periapical radiographs will be done initially to determine the level of bone using a standard periapical parallel technique with digital sensor.
* The patients will undergo full mouth one stage debridement using ultrasonic scalers, manual scalers and curettes.
* Full mouth periodontal charting and samples from gingival crevicular fluid will be obtained using a sterile perio-paper inserted into the deepest periodontal pocket with horizontal bone loss immediately after finishing phase I therapy.
* Melaleuca Alternifolia Gel will be gently administered in the deepest pocket by syringe with blunt tip and the syringe will be removed slowly to avoid injuring the tissues for group I patients after phase 1 therapy by two weeks.
* After 3 months of phase I therapy, the patients will be followed up with evaluation of the clinical parameters.
Social \& scientific values: Provide the dentists a more convenient way to reduce periodontal pockets in periodontitis patient by locally applying Melaleuca Alternifolia gel as an adjunct to non-surgical periodontal debridement.
Risks to study participants: The participants are not subjected to any risks.
Benefits to study participants:
Since the main objective of the research is using tea tree oil as a local delivery drug in the gel form to be placed in periodontal pockets as an adjunct to non-surgical periodontal debridement for the management of localized periodontitis, the benefit of the research is to provide the patient better therapeutic effect and a safe local delivery drug with no adverse reactions.
Benefits of the study to the community: Determination of the impact of tea tree oil gel on the level of Tumor necrosis factor-alpha (TNF-α) in the gingival crevicular fluid.
Privacy, Record keeping \& confidentiality: All patients' data, information and study results will be kept under strict confidentiality and will be stored and kept as required. Only the primary researcher and the main investigator will have access to such data during the period of the study. At the end of the study all participants will be informed with the results and outcomes of the study as well as any health issues if found concerning them.
The study has been approved and accepted by the Diagnosis, Oral Medicine and Periodontology Department as approved by the endorsement released from the departments' committee with the code: OMD-2021-11 on Sunday 7/11/2020.
