Clean and Fresh Mouthwash Inflammatory Response Markers Study

Written by Kourosh Maddahi — July 16, 2020

Goal: The goal of this study was to determine the effect of Lumineux Oral Essentials Clean and Fresh Mouthwash® vs. a placebo on crevicular fluid markers of inflammation.

Materials and Methods: This prospective, randomized, controlled, double-blind study was conducted in 50 subjects.

Study Overview: Eligibility was determined by baseline measurements performed before study begin. Once eligibility was determined, 50 subjects were enrolled. Subjects were randomly assigned ( in a 1:1 ratio to treatment with either the test mouthwash (Lumineux Oral Essentials Clean and Fresh Mouthwash®, Los Angeles CA 90026) or a control rinse containing water and flavoring only.

Subjects were instructed to rinse with one capful of their allocated mouthwash for 60 seconds after breakfast and again before bedtime. No eating or drinking was allowed for 30 mins after rinsing. Subjects were instructed to continue with their usual oral hygiene regimen. They used the study materials for 30 days and returned used mouth rinse containers at each visit. Each returned container was weighed to measure compliance. Subjects were evaluated at Baseline (Day 0) and Day 30.

Sample Collection: The two to four sites that had the most severe inflammation as determined by visual examination and periodontal probing were selected in each patient. Standard gingival crevicular fluid (GCF) collection techniques were used. First, sites were isolated with cotton rolls and gently air dried. Fluid samples were collected sequentially with 3 sterile Periopaper strips (Oraflow Inc., Planview, NT, USA) that were inserted into the gingival crevice until mild resistance was felt and then left in place for 30 seconds. After GCF collection, all 3 strips from the same site were promptly placed in one single, empty 1.5 ml Eppendorf vial and immediately frozen at −80°C until use [1]. Samples were transported in dry ice to a commercial biomarker assay laboratory (Westcoast Biosciences, Irvine, CA, USA) where they were processed by a blinded technician using the standard Luminex assay method (Luminex Corporation, Austin, TX, USA) [1].

Evaluation Criteria: Markers of inflammation were identified from crevicular fluid on Day 0 and Day 30.

The gingival index (G.I.) was recorded by a blinded, pre-standardized periodontist on Day 0 and Day 30.

Crevicular Fluid markers: IL-1β, TNF-α, Day 30 vs baseline

Clinical Indices: Gingival Index (G.I.): scale 0-3, Day 30 vs baseline

1. Lumineux Oral Essentials Clean and Fresh Mouthwash® ((Lumineux Oral Essentials, Los Angeles CA 90026).

Ingredients: Organic aloe barbadensis (aloe vera) leaf juice, xylitol*, purified water (aqua), dead sea salt (maris sal), gaultheria procumbens (wintergreen) leaf oil, mentha viridis (spearmint) leaf oil, organic mentha piperita (peppermint) leaf oil, ocimum basilicum (basil) oil, eugenia caryophyllus (clove) flower.

(1). Results:

1. Gingival Index After 30 days, the Gingival Index was reduced by 0.41 (SD 0.25) in the test group, whereas it increased by 0.02 (SD 0.27) in the control group. In the test group the difference in G.I. between Day 30 and Day 0 was significant at p=0.037. In the control group, G. I. did not change significantly (p>0.1).

2. Crevicular Fluid TNF-α After 30 days, the crevicular fluid TNF-α was reduced by 2,100.7pg/ml (53.8%) (SD 814) in the test group, whereas it was reduced by 850pg/ml (23.9%) (SD 784) in the control group. In the test group, the difference in TNF- α concentrations between Day 30 and Day 0 was significant at p=0.028. In the control group there was no significant change (p>0.1).

3. Crevicular Fluid IL-1β After 30 days, the crevicular fluid IL-1β was reduced by 18,582.3 pg/ml (47%) (SD 8,156) in the test group, whereas it increased by 2,680pg/ml (15%) (SD 4,763) in the control group. In the test group, the difference in IL-1β concentrations between Day 30 and Day 0 was significant at p=0.045. In the control group there was no significant change (p>0.1).

Conclusion: In subjects with moderate-to-severe gingival inflammation, a test mouthwash used twice daily for 30 days significantly reduced Crevicular Fluid IL-1β and TNF-α as well as G.I.
