Brief Summary

The goal of this clinical trial is to learn if daily oil pulling with coconut oil or sesame oil works as effectively as a standard mouthwash to treat gum swelling and redness (gingivitis) in adults aged 18 to 55 years. The main questions it aims to answer are:

  • Does daily oil pulling with virgin coconut oil or sesame oil reduce dental plaque buildup as effectively as 0.2% chlorhexidine mouthwash over an 8-week period?
  • Does oil pulling reduce gum inflammation, bleeding, and tongue coating while avoiding common mouthwash side effects such as tooth staining?
  • Does oil pulling improve oral health-related quality of life and overall patient satisfaction? Researchers will compare three groups - participants using virgin coconut oil, participants using sesame oil, and participants using 0.2% chlorhexidine mouthwash - to evaluate changes in oral health over 8 weeks. Participants will:
  • Receive professional dental cleaning (scaling) and standardized toothbrushing instructions at the start of the study.
  • Swish 10 mL of their assigned oil for 7 minutes once daily in the morning on an empty stomach, or rinse with 10 mL of chlorhexidine mouthwash for 1 minute at night, every day for 8 weeks (56 days).
  • Visit the dental clinic at baseline (Day 0), week 4 (Day 28), and week 8 (Day 56) for clinical oral exams, salivary pH testing, and short surveys on comfort and satisfaction. 2\.

Outcome Measures

Primary Outcomes (2)

  • Change in Silness and Loe Plaque Index (PI) Score

    valuation of dental plaque accumulation (thickness of bacterial biofilm at the gingival margin) measured across 4 tooth surfaces (buccal, lingual, mesial, distal) and averaged across examined teeth. Score ranges from 0 to 3 (0 = No plaque, 1 = Thin film detectable by probing, 2 = Moderate deposits visible to naked eye, 3 = Abundant heavy plaque buildup). Lower scores indicate better oral hygiene.

    Baseline (Day 0), Week 4 (Day 28), and Week 8 (Day 56)

  • Change in Gingival Index (GI) Score by Loe and Silness

    Assessment of gingival inflammation severity evaluated across 4 tooth surfaces based on color, consistency, and bleeding on gentle probing. Score ranges from 0 to 3 (0 = Normal gingiva with no inflammation, 1 = Mild inflammation with slight erythema and no bleeding, 2 = Moderate inflammation with redness and bleeding on probing, 3 = Severe inflammation with marked redness, edema, and tendency to spontaneous bleeding). Lower scores indicate reduced gingival inflammation.

    Baseline (Day 0), Week 4 (Day 28), and Week 8 (Day 56)

Secondary Outcomes (5)

  • Change in Winkel Tongue Coating Index (WTCI) Score

    Baseline (Day 0), Week 4 (Day 28), and Week 8 (Day 56)

  • Change in Modified Lobene Stain Index (MLSI) Score

    Baseline (Day 0), Week 4 (Day 28), and Week 8 (Day 56)

  • Change in Salivary pH Level

    Baseline (Day 0), Week 4 (Day 28), and Week 8 (Day 56)

  • Change in Oral Health Impact Profile-14 (OHIP-14) Total Score

    Baseline (Day 0), Week 4 (Day 28), and Week 8 (Day 56)

  • Patient-Reported Visual Analog Scale (VAS) Scores and Satisfaction

    Baseline (Day 0), Week 4 (Day 28), and Week 8 (Day 56)
