Trial Outcomes & Findings for Effect of a Commercial Cosmetic Mouth Rinse on Plaque Re-growth (NCT NCT01122862)

NCT ID: NCT01122862

Last Updated: 2013-09-09

Results Overview

Plaque scores were assessed using Turesky Modification of the Quigley Hein Index and categorized as 0: No plaque; 1: Slight flecks of plaque at the cervical margin of the tooth;2: A thin continuous band of plaque (1 mm or smaller) at the cervical margin of the tooth;3: A band of plaque wider than 1 mm but covering less than 1/3 of the crown of the tooth;4: Plaque covering at least 1/3 but less than 2/3 of the crown of the tooth;5: Plaque covering 2/3 or more of the crown of the tooth. The interproximal plaque index was calculated by taking the average of plaque scores over the mesiofacial, distofacial, mesiolingual and distolingual surfaces in the upper and lower jaws for a participant.

Measure
Test Mouth Rinse
Participants swirled their oral cavity with 15 milliliters (mL) of commercially available test mouth rinse for 60 seconds and expectorated. Each treatment was administered twice daily for 4 days.
Chlorhexidine Mouth Rinse (0.12%)
Participants swirled their oral cavity with 15 mL of commercially available 0.12% weight by volume (w/v) chlorhexidine mouth rinse for 30 seconds and expectorated. Each treatment was administered twice daily for 4 days.
Sterile Water
Participants swirled their oral cavity with 15 mL of sterile water for 60 seconds and expectorated. Each treatment was administered twice daily for 4 days.

PRIMARY outcome

Timeframe: Day 4 post treatment administration

Population: Intention to Treat (ITT) population: All randomized participants who received study treatment and had at least one post-baseline efficacy measurement. Due to drop outs, there was difference in number of participants analyzed for this outcome measure. Missing data was not imputed.

Plaque scores were assessed using Turesky Modification of the Quigley Hein Index and categorized as 0: No plaque; 1: Slight flecks of plaque at the cervical margin of the tooth;2: A thin continuous band of plaque (1 mm or smaller) at the cervical margin of the tooth;3: A band of plaque wider than 1 mm but covering less than 1/3 of the crown of the tooth;4: Plaque covering at least 1/3 but less than 2/3 of the crown of the tooth;5: Plaque covering 2/3 or more of the crown of the tooth. The interproximal plaque index was calculated by taking the average of plaque scores over the mesiofacial, distofacial, mesiolingual and distolingual surfaces in the upper and lower jaws for a participant.
