Clinical Investigation to Examine Toothpaste Effect on Oral Bacteria

Phase 4

Completed

• Conditions: Oral Bacteria Levels in the Mouth
• Interventions: Drug: Total Flavor option 2; Drug: Total Flavor option 1

• Registration Number: NCT02194621
• Lead Sponsor: Colgate Palmolive

Brief Summary

The primary objective was to evaluate the antibacterial effects of two toothpastes containing 0.3% triclosan, 2% copolymer and 0.234% sodium fluoride in a silica base as compared to a control regular fluoride toothpaste on anaerobic and malodor bacteria 12 hours after 13 days of product use. A secondary objective was to demonstrate that a toothpaste containing 0.3% triclosan, 2% copolymer, 0.234% sodium fluoride and a flavor with odor-masking ingredients in silica base (Colgate Total Toothpaste-Flavor Option 1) provides a level of antibacterial efficacy that is "equivalent" to a toothpaste containing 0.3% triclosan, 2% copolymer, 0.234% sodium fluoride and a regular flavor in silica base (Colgate Total Toothpaste-Flavor Option 2) after 13 days of product use.

Arm && Interventions

Group	Intervention	Description
Total Flavor Option 2	Total Flavor option 2	Total toothpaste containing triclosan/copolymer/sodium fluoride with new OM (oral malodor) complex 2 ingredient. Total Flavor Option 2
Total Flavor Option 1	Total Flavor option 1	Total toothpaste containing triclosan/copolymer/sodium fluoride with new OM (oral malodor) complex 1 ingredient - Total Flavor Option 1

Primary Outcome Measures

Name	Time	Method
Anaerobic Bacteria	12 hours	Subjects brush their teeth with assigned toothpaste 2x/day for 13 days. On clinic visit day, subjects brush their teeth and return 12 hours later for clinical evaluation. Samples of dental plaque at the gumline will be collected for microbiological analysis to determine total levels of anaerobic bacteria CFU - colony forming units.
Malodor Bacteria (Breath Odor Causing Bacteria)	12 hours	Subjects brush their teeth with assigned toothpaste 2x/day for 13 days. On clinic visit day, subjects brush their teeth and return 12 hours later for clinical evaluation. Samples of dental plaque at the gumline will be collected for microbiological analysis to determine levels of mouth odor causing bacteria CFU - colony forming units.
