What this Trial Is About
Researchers are evaluating the effect of a chewing gum containing an active compound called MIIP-E2 on dental plaque formation using a 4-day plaque accumulation model. This single-blind, randomized controlled trial involves 32 adult subjects who will participate in three treatment periods, each lasting four days. The study compares an active MIIP-E2 gum, a placebo gum without the active compound, and a no-gum control regimen to assess their impact on dental plaque buildup.
The trial uses a 3-way crossover design where each participant experiences all three treatments in different sequences, with approximately 10-day washout periods between treatments. During each 4-day treatment period, participants will refrain from oral hygiene practices and use the assigned gum product three times daily for 10 minutes after meals, chewing on each side of the mouth for one minute before chewing freely. Compliance will be monitored using daily diaries.
Participants will undergo oral examinations, plaque assessments, saliva sample collections, and intraoral photographs at baseline and after each treatment period. The primary outcome is the amount of dental plaque measured after four days of intervention. Additional assessments include DNA sequencing of oral bacteria and visual plaque evaluations. The study includes safety and compliance checks and lasts through the three treatment periods with washouts in between.

Factors
Experimental MIIP-E2 Gum
Placebo Gum
Routine Tooth Brushing (Guideline Standard)
What it is
Chewing gum containing ultrapure bovine lactoferrin (MIIP-E2), used three times daily for four days, with no tooth brushing allowed.
A gum identical in appearance, taste, and texture but lacking MIIP-E2; also used three times daily for four days, with no tooth brushing.
Daily mechanical removal of dental plaque using a toothbrush and toothpaste, performed twice per day, as recommended by guidelines.
Role in trial
Investigational regimen being tested for its ability to limit short-term dental plaque accumulation.
Placebo control designed to match chewing action and study procedures without active lactoferrin ingredient.
Routine care option outside the trial, representing the mainstay for preventing dental plaque in daily life.
Primary use
Evaluated for reducing dental plaque buildup in the absence of brushing over a four-day period.
Serves as a control to determine the effect of chewing action alone, separate from any effect of MIIP-E2.
Prevents dental plaque accumulation and reduces risk of gum disease through regular mechanical cleaning.
How it is given or performed
Participants chewed MIIP-E2 gum three times daily after meals for 10 minutes each use, with specific protocol for alternating chewing sides.
Used following the same schedule, frequency, and chewing instructions as the MIIP-E2 gum, but without the active ingredient.
Brushing teeth thoroughly twice a day with a manual or electric toothbrush and standard toothpaste.
Evidence status
Currently being investigated; no efficacy results from this trial are published yet. Related antimicrobial lactoferrin or chewing gum products have shown plaque-reducing effects in other controlled studies.
Aims to measure if chewing alone (without active ingredient) reduces plaque; no published results from this trial yet. Chewing gum in general may offer mechanical clearance but is less effective than brushing.
Established, robust evidence from guidelines and reviews supports brushing with toothpaste as the gold standard for preventing dental plaque and gum disease.
Important limitations
Trial setting involved suspension of daily brushing, which is not typical for everyday practice. Long-term effects and generalizability to high-risk populations or routine use are unknown.
Serves as a control only for four-day, no-brushing conditions; limited relevance to routine oral care. Chewing gum may not substitute for mechanical cleaning in daily life.
Effectiveness of brushing depends on individual technique, consistency, and manual dexterity; some populations may need alternative or additional methods.

Implementation
Duration - 3 periods of 4 days each with approximately 10-day washout periods between treatments
Participants undergo three separate 4-day treatment periods using one of three regimens: an active compound gum, a placebo gum, or no gum. During each 4-day treatment period, participants refrain from oral hygiene procedures and use the assigned gum three times daily for 10 minutes after meals or no gum depending on the regimen. Compliance is monitored using a diary. After each treatment period, participants attend an end-of-regimen visit for dental plaque assessments and oral examinations.
1 baseline visit and 3 end-of-regimen visits (one after each treatment period)
