MI Paste Plus for lowering Streptococcus mutans and preventing white spot lesions during fixed orthodontic treatment
Effect of MI Paste Plus™ on Streptococcus Mutans Counts and White Spot Lesions in Patients With Fixed Orthodontic Appliances: A Triple-Blind Clinical Trial
This trial will test whether daily application of MI Paste Plus reduces Streptococcus mutans levels and prevents white spot lesions in people aged 5–45 who wear fixed braces.

What this trial studies
Participants with fixed orthodontic appliances will be assigned to apply either MI Paste Plus (CPP-ACP with fluoride) or a bioadhesive placebo gel according to the study protocol. Investigators will collect saliva and plaque samples and will photograph and score white spot lesions at baseline and at scheduled follow-up visits to track changes over time. MI Paste Plus releases calcium, phosphate, and fluoride ions intended to promote remineralization and alter biofilm composition, while the placebo controls for gel application effects. Outcomes will compare shifts in S. mutans counts and lesion development between the groups during orthodontic treatment.
Who should consider this trial
Good fit: Ideal candidates are otherwise healthy people aged 5–45 who are receiving fixed orthodontic appliances and have no active untreated caries or other exclusion conditions.
Not a fit: Patients with advanced white-spot lesions involving dentin, active untreated caries, recent antibiotic use, removable-appliance treatment, tobacco use, relevant medical conditions, or allergies noted in the exclusion criteria are unlikely to benefit from participation.
Why it matters
Potential benefit: If successful, this could reduce enamel demineralization and lower S. mutans levels in patients with braces, decreasing white spot lesions and improving long-term tooth health.
How similar studies have performed: Previous research supports that fluoride combined with CPP-ACP can enhance enamel remineralization, so MI Paste Plus has prior evidence of benefit though results specifically in fixed-appliance populations vary.
