Dental health, oral microbiome, and gum disease
Interventions
Oil Pulling
Ayurvedic practice of swishing oil in the mouth for 15-20 minutes to improve oral hygiene and reduce harmful bacteria
Tongue Scraping
Using a metal or plastic scraper to remove bacteria, debris, and coating from the tongue surface for fresher breath and oral hygiene
Miswak Stick
Traditional teeth-cleaning twig from Salvadora persica with natural antimicrobial compounds, endorsed by the WHO as an effective oral hygiene tool
Studies
Effect of oil pulling on Streptococcus mutans count in plaque and saliva using Dentocult SM Strip mutans test: a randomized, controlled, triple-blind study
Oil pulling with sesame oil for 10 minutes daily reduced Streptococcus mutans (cavity-causing bacteria) in saliva by 20% after 2 weeks.
Effect of oil pulling on plaque induced gingivitis: A randomized, controlled, triple-blind study
Oil pulling with sesame oil was as effective as chlorhexidine mouthwash in reducing plaque and gingivitis over 10 days.
Effect of coconut oil in plaque related gingivitis - A preliminary report
Daily coconut oil pulling for 30 days significantly reduced plaque and gingivitis scores, with effects comparable to chlorhexidine mouthwash.
Tongue cleaning methods: a comparative clinical trial employing a toothbrush and a tongue scraper
Tongue scrapers were more effective than toothbrushes at removing tongue coating and reducing volatile sulfur compounds that cause bad breath.
The effectiveness of miswak (Salvadora persica L. and Azadirachta indica A.Juss.) practices in reducing plaque and gingivitis among adults: A systematic review and meta-analysis.
Meta-analysis of 10 RCTs shows miswak is comparable to toothbrushing for plaque (SMD 0.39, p=0.08) and gingivitis (SMD 0.13, p=0.37), with adjunctive miswak use significantly superior for both outcomes.
The antiplaque/anticariogenic efficacy of Salvadora persica (Miswak) mouthrinse in comparison to that of chlorhexidine: a systematic review and meta-analysis.
Salvadora persica extracts demonstrate clear antiplaque and anticariogenic effects with Level Ia evidence and Class A recommendation strength, though inferior to chlorhexidine gold standard.
The immediate antimicrobial effect of a toothbrush and miswak on cariogenic bacteria: a clinical study.
Miswak produces significantly greater reduction in Streptococcus mutans compared to toothbrushing (p=0.013), demonstrating immediate antimicrobial action from the chewing stick's bioactive compounds.
Tongue scraping for treating halitosis.
Cochrane review of 2 trials (40 participants) finds tongue scrapers produce a statistically significant reduction in volatile sulfur compounds compared to toothbrushes, though evidence quality is weak.
Effectiveness of mechanical tongue cleaning on breath odour and tongue coating: a systematic review.
Systematic review of 5 studies (3 RCTs, 2 CCTs) confirms mechanical tongue cleaning reduces oral malodour and tongue coating when added to regular toothbrushing.
The short-term treatment effects on the microbiota at the dorsum of the tongue in intra-oral halitosis patients--a randomized clinical trial.
Randomized crossover trial in 21 halitosis patients shows tongue scraping alone does not significantly reduce halitosis-associated bacteria, suggesting its primary benefit is mechanical debris removal rather than antimicrobial action.
