Effectiveness of an Oral Care Protocol Based on Lactoferrin Toothpaste and Mouthwash in Pregnant Women for the Prevention of Periodontal Disease: A Randomized Controlled Clinical Trial

Not applicable Interventional University of Pavia · NCT07069140

This will test whether adding a lactoferrin mouthwash to lactoferrin toothpaste plus regular professional cleanings improves gum health in pregnant women 14–28 weeks into pregnancy.

What this trial studies

This randomized, controlled trial will enroll 40 pregnant women in their second trimester and randomly assign them to two home-care regimens combined with professional dental cleanings every three months. The intervention group will use both a lactoferrin-based toothpaste and lactoferrin-based mouthwash, while the control group will use only the lactoferrin-based toothpaste. Participants will be followed for six months with periodic periodontal examinations. The primary outcome is reduction in dental plaque measured by the Plaque Index, with secondary outcomes including gingival inflammation, probing pocket depth, clinical attachment level, and other periodontal indices.

Who should consider this trial

Good fit: Women aged 18–45 who are 14–28 weeks pregnant, have periodontitis (Stages I–III, Grades A–B), at least 20 natural teeth, and can attend follow-up visits are ideal candidates.

Not a fit: People with systemic diseases affecting periodontal status, recent antibiotic or periodontal treatment, current smokers, those with high-risk pregnancies or allergies to product components, or those using conflicting medications/supplements are unlikely to benefit or may be excluded.

Why it matters

Potential benefit: If successful, this approach could reduce dental plaque and gum inflammation during pregnancy using accessible home oral-care products alongside routine cleanings.

How similar studies have performed: Laboratory work and small clinical studies suggest lactoferrin can reduce oral pathogens and plaque, but this specific lactoferrin mouthwash-plus-toothpaste regimen in pregnant women is relatively novel and not yet widely proven.
