Efficacy of Locally Delivered Tea Tree Oil Gel as an Adjunct to Non-surgical Periodontal Management; A Randomized Controlled Clinical Trial

Abstract

Objective: The aim of this controlled randomized clinical trial is to assess the clinical impact of intra pocket application of Tea Tree Oil (TTO) gel. Methods and materials: Twenty-two patients, both genders, aged 20 to 50, were diagnosed with moderate to severe periodontitis. Two groups were selected: the test group, which included eleven patients who received both nonsurgical periodontal therapy (NSPT) and locally delivered TTO gel, and the control group, which included eleven patients who received only NSPT. The following parameters were considered clinically at baseline and three months after NSPT: plaque index (PI), modified sulcular bleeding index (MSBI), probing depth (PD), and clinical attachment level (CAL). Patient Satisfaction Questionnaire Short Form (PSQ-18) was assessed postoperatively in both groups. Results: Three months postoperatively, the clinical data shows better improvement in test group than in control group. PSQ-18 showed improvement in patient satisfaction in both groups. Conclusion: Adjunctive local delivery of TTO gel together with NSPT in severe periodontitis has better effect clinically than that of NSPT alone.
