Is this trial a fit for you?

Likely a good fit

Ideal candidates are healthy adults aged 18–65 with at least 20 natural teeth and a baseline plaque index score of 2 or greater who can comply with temporary restrictions on oral hygiene.

Probably not a fit

People with active oral disease, extensive restorations or orthodontic bands, significant systemic conditions or medications affecting oral health, or those unable to attend in-person visits are unlikely to benefit from this study.

What this trial studies

This single-blind, single-center, randomized 3-way crossover trial enrolls 32 adults and compares three 4-day treatment periods: MIIP-E2 gum, an inactive (placebo) gum, and no gum. Each participant receives all three regimens in randomized sequence with approximately 10-day washout periods between treatment periods. Participants refrain from oral hygiene during each 4-day accumulation period and plaque is measured using a validated index. The trial is conducted at the Oral Health Research Institute in Indianapolis under oversight from Lactea Therapeutics with collaboration from Indiana University.

Why it matters

Potential benefit: If successful, the MIIP-E2 gum could reduce short-term plaque buildup and lower short-term risk factors for gingivitis.

How similar studies have gone: Previous plaque-accumulation models and chewing-gum interventions have shown modest plaque reductions, but MIIP-E2 itself is a novel compound with limited prior clinical data.
