Brief summary

The purpose of this study is to investigate the efficacy of an experimental dentifrice, containing 0.454 percent (%) stannous fluoride and 0.3% zinc chloride, to reduce oral malodor, compared to a marketed regular fluoride dentifrice after 3 weeks twice daily brushing in a population of clinically diagnosed gingivitis.

Detailed description

This will be a single center, single blind (to the examiners undertaking the oral malodor assessments), randomized (stratified by the participant's sex), controlled, two arm parallel study in volunteers with clinically diagnosed gingivitis and oral malodor. The study will evaluate the clinical efficacy of an experimental dentifrice containing 0.454% stannous fluoride and 0.3% zinc chloride to reduce oral malodor after 3 weeks of twice-daily use compared to a regular reference dentifrice. Sufficient participants will be screened to randomize approximately 106 participants to study treatment (approximately 53 per treatment group) to ensure approximately 100 evaluable participants complete the study.

Interventions

Dentifrice containing 0.454% stannous fluoride with 0.3% zinc chloride.

Having at least 20 natural (vital) teeth. 2. Good oral health without lesions in the oral cavity (including the tongue) that could interfere with the study evaluations. 3. Having clinically diagnosed, plaque-induced gingivitis defined as having 10-30% bleeding sites from the bleeding on probing assessment. 4. At Screening (Visit 1) and prior to brushing with assigned dentifrice at Baseline (Visit 2) participants must provide 2 samples of mouth air, which must have a mean hydrogen sulfide concentration greater than 150ppb. There must be less than or equal to (\<=)500ppb difference between the values measured at screening and baseline (pre-brushing). 5.

MeasureTime frameDescription
Adjusted Mean Change From Baseline (Day 0, Pre-Brushing) to Week 3 (Pre-Brushing) in Breath Organoleptic ScoresBaseline (Day 0, Pre-Brushing) and Week 3 (Pre-Brushing)An organoleptic assessment was used to evaluate the oral odor and defined as a method that measures the strength of target odor and expresses the value in terms of a score with reference to a pre-defined organoleptic scale. The assessors evaluated the oral odor and scored from 0 (lowest score) to 5 (highest score), where 0= No appreciable odor, 1= Barely noticeable odor, 2= Slight but clearly noticeable odor, 3= Moderate odor, 4= Strong odor, 5= Extremely foul odor. Lower score indicates improvement. The change from Baseline was calculated as score at Week 3 (Pre-Brushing) minus score at Baseline (Day 0, Pre-Brushing). Baseline was defined as Day 0 (Pre-Brushing). Analysis was performed using Analysis of Covariance (ANCOVA) method.

Experimental Dentifrice
In this arm, eligible participants applied a ribbon of experimental dentifrice (0.454% stannous fluoride with 0.3% zinc chloride) to the toothbrush head and brushed their teeth under supervision for one timed minute on Visit 2 (1 to 3 weeks after screening). One hour (+/-5 minutes) post-brushing, participants had their post-brushing assessments and were instructed to brush twice daily (for 1 minute, morning and evening) with experimental dentifrice for the next 3 weeks until their next visit (Visit 3). At Visit 3 (Week 3), participants received the experimental dentifrice and underwent pre-brushing and post-brushing assessments in the same manner as performed at the Visit 2.

Reference Dentifrice
In this arm, eligible participants applied a ribbon of reference dentifrice (0.243% sodium fluoride) to the toothbrush head and brushed their teeth under supervision for one timed minute on Visit 2 (1 to 3 weeks after screening). One hour (+/-5 minutes) post-brushing, participants had their post-brushing assessments and were instructed to brush twice daily (for 1 minute, morning and evening) with reference dentifrice for the next 3 weeks until their next visit (Visit 3). At Visit 3 (Week 3), participants received the reference dentifrice and underwent pre-brushing and post-brushing assessments in the same manner as performed at the Visit 2.

Adjusted Mean Change From Baseline (Day 0, Pre-Brushing) to Week 3 (1 Hour Post-Brushing) in Total VSC Concentration in Breath

The VSCs concentration in breath sample was evaluated using the OralChroma Halitosis Measuring instrument. A clean and sterile OralChroma syringe was used to obtain a sample of the mouth air of the participant. The OralChroma is a portable gas chromatograph with a highly sensitive semiconductor gas detector which can determine the concentration of the three main VSCs in breath (hydrogen sulfide, methanethiol and dimethyl sulfide). The concentration values (ppb) of hydrogen sulfide, methanethiol and dimethyl sulfide were recorded separately, and the adjusted mean of total VSCs concentration was reported. The change from Baseline was calculated as value at Week 3 (1 Hour Post-Brushing) minus value at Baseline (Day 0, Pre-Brushing). Baseline was defined as Day 0 (Pre-Brushing).

Adjusted Mean Change From Baseline (Week 3, Pre-Brushing) to Week 3 (1 Hour Post-Brushing) in Breath Organoleptic Scores

An organoleptic assessment was used to evaluate the oral odor and defined as a method that measures the strength of target odor and expresses the value in terms of a score with reference to a pre-defined organoleptic scale. The assessors evaluated the oral odor and scored from 0 (lowest score) to 5 (highest score), where 0= No appreciable odor, 1= Barely noticeable odor, 2= Slight but clearly noticeable odor, 3= Moderate odor, 4= Strong odor, 5= Extremely foul odor. Lower score indicates improvement. The change from Baseline was calculated as score at Week 3 (1 Hour Post-Brushing) minus score at (Week 3, Pre-Brushing). Baseline was defined as Week 3 (Pre-Brushing).
