Randomized controlled trial evaluating concurrent gingivitis and stain effects of a two-step dentifrice/gel sequence

Area of Science:

• Oral Hygiene
• Periodontology
• Cosmetic Dentistry

Background:

• Gingivitis and extrinsic tooth stain are common oral health concerns.
• Effective oral hygiene practices are crucial for managing these conditions.
• Existing treatments may offer limited efficacy for concurrent improvement.

Purpose of the Study:

• To evaluate the clinical effectiveness of a two-step oral hygiene sequence.
• The sequence involved a stannous fluoride (SnF₂) dentifrice followed by a hydrogen peroxide (H₂O₂) whitening gel.
• To assess improvements in gingivitis and extrinsic stain compared to a control group.

Main Methods:

• A randomized controlled trial was conducted with healthy adults exhibiting gingivitis and extrinsic stain.
• Subjects were randomized to either the two-step dentifrice/whitening gel sequence or a control dentifrice.
• Gingivitis was measured using the Gingivitis Bleeding Index (GBI), and stain using the Lobene Stain Index (LSI).

Main Results:

• The two-step regimen demonstrated statistically significant reductions in both gingivitis and extrinsic stain after one week (P<0.0001).
• Adjusted mean changes showed greater improvement in GBI and LSI for the two-step sequence compared to the control.
• Similar significant differences were observed at Week 3, with treatments being well-tolerated.

Conclusions:

• The two-step 0.454% SnF₂ dentifrice and 3% H₂O₂ whitening gel sequence offers a clinically significant improvement in gingivitis and extrinsic stain.
• This regimen provides concurrent benefits for both oral health and aesthetic concerns.
• The findings support the use of this two-step approach as an effective oral hygiene strategy.
