Key Takeaway
Randomized crossover trial found coconut oil and sesame oil equally effective for inhibiting plaque regrowth, with nearly identical plaque index scores (1.60 vs 1.49).
Summary
This randomized crossover trial directly compared the two most commonly used oils for oil pulling - coconut oil and sesame oil - in 24 participants. After professional tooth cleaning, participants used either coconut or sesame oil for 4-day pulling cycles with a 14-day washout period before switching oils. Plaque regrowth, gingival inflammation, tooth staining, and bleeding were all comparable between the two oils. The findings suggest that either coconut or sesame oil can be used for oil pulling with equivalent plaque-inhibition effects, giving practitioners flexibility in oil choice based on personal preference.
Methods
- Randomized, observer-masked, crossover clinical trial
- 24 participants
- Professional tooth cleaning followed by 4-day oil pulling cycles
- 14-day washout period between crossover
- Measured plaque index, gingival index, stain index, and bleeding on probing on day 5
Key Results
- Plaque index nearly identical: coconut oil 1.60 +/- 0.28 vs sesame oil 1.49 +/- 0.22
- Tooth staining similar: coconut 0.20 +/- 0.11 vs sesame 0.21 +/- 0.09
- Gingival inflammation and bleeding comparable between groups
- No significant differences between oils for any measured outcome
Limitations
- Small sample size (n=24)
- Short intervention period (4 days per oil)
- Does not compare to no-oil control group
- Only measured plaque regrowth, not long-term oral health outcomes
