Effectiveness of an Essential Oil Mouthwash on Halitosis in Obese Patients with Periodontitis: A Short-Term Clinical Evaluation.

Background

Halitosis is a common condition often rooted in periodontal disease and exacerbated by systemic disorders such as obesity. This short-term clinical evaluation investigates the relationship between halitosis, obesity, and periodontitis, and assesses the efficacy of a natural essential oil mouthwash as an adjunctive oral hygiene intervention.

Methods

In this randomized, placebo-controlled clinical trial, 45 obese patients with diagnosed periodontitis and self-reported halitosis were randomly assigned to either a test group (n = 30), receiving an essential oil-based mouthwash, or a control group (n = 15), receiving a placebo. Over 28 days, participants were evaluated using plaque index (PI), bleeding on probing (BOP), organoleptic scoring, and BANA test results. Both subjective and objective halitosis assessments were performed.

Results

The test group showed marked improvements in all parameters compared to controls. PI decreased by 31.5% in the test group versus 9.25% in controls; BOP reduced by 34.5% versus 6.0%; BANA test positivity dropped by 38.1% in the test group. Organoleptic scores improved by 45.9% (examiner-rated) and 36.8% (self-assessed) in the test group.

Conclusions

This 28-day clinical evaluation demonstrates the potential of an essential oil-based mouthwash to significantly reduce halitosis and periodontal inflammation in obese individuals with periodontitis. The necessity of future randomized trials is evident to substantiate the sustained benefits and safety of the intervention.
