Conditions

Dental Plaque, Gingivitis

Brief summary

The main goal of this study is to evaluate and compare the efficacy of an on-market dentifrice containing 67 percent (%) sodium bicarbonate and 0.31% sodium fluoride to a reference regular fluoride dentifrice on treating gingival bleeding and gingival inflammation as well as reducing plaque accumulation in population with gingivitis after 12 weeks use.

Detailed description

This will be a single center, controlled, single blind (examiner blind), randomized, two treatment arm, parallel study in volunteers with clinically measurable levels of gingivitis (defined as those with 10-30% bleeding sites on probing). Approximately 200 participants (100 per group) will be randomized to ensure 188 evaluable participants (94 per group) complete the study.

MeasureTime frameDescription
Adjusted Mean Change From Baseline in Number of Bleeding Sites at Week 12Baseline and Week 12The number of bleeding sites was calculated using the bleeding index (BI) assessment. The BI was assessed for all evaluable surfaces (having two-thirds of the natural tooth surface gradable for the assessment) of the facial and lingual/palatal gingiva, 6 sites per tooth (mesiobuccal, buccal, and distobuccal; mesiolingual/palatal, lingual/palatal, and distolingual/palatal). Evaluable tooth sites were probed, and gingival bleeding was assessed for approximately 30 seconds after probing. The number of bleeding sites for each participant was calculated as the number of evaluable tooth sites with bleeding observed immediately on probing or within 30 seconds of probing. Change from Baseline was calculated by subtracting the Baseline value from the value at Week 12. Baseline was defined as Day 0. A negative change from Baseline indicated improvement in gingival bleeding.

Adjusted Mean Change From Baseline in Number of Bleeding Sites at Week 12

The number of bleeding sites was calculated using the bleeding index (BI) assessment. The BI was assessed for all evaluable surfaces (having two-thirds of the natural tooth surface gradable for the assessment) of the facial and lingual/palatal gingiva, 6 sites per tooth (mesiobuccal, buccal, and distobuccal; mesiolingual/palatal, lingual/palatal, and distolingual/palatal). Evaluable tooth sites were probed, and gingival bleeding was assessed for approximately 30 seconds after probing. The number of bleeding sites for each participant was calculated as the number of evaluable tooth sites with bleeding observed immediately on probing or within 30 seconds of probing. Change from Baseline was calculated by subtracting the Baseline value from the value at Week 12. Baseline was defined as Day 0. A negative change from Baseline indicated improvement in gingival bleeding.

TPI was used to assess plaque on the facial and lingual surfaces of each scorable tooth (7-7 in each arch). 3 scores were recorded facially (distal, mesial sites), and 3 scores were recorded lingually (distal, mesial sites). Plaque was first disclosed using a dye solution and scored on a 6-point scale ranging from 0 to 5, where 0=No plaque; 1=Separate flecks of plaque at the cervical margin; 2=Thin continuous band of plaque (up to 1 mm) at the cervical margin; 3=Band of plaque wider than 1 mm but covering \<1/3 of the tooth surface; 4=Plaque covering \>=1/3 but \<2/3 of the tooth surface; 5=Plaque covering \>=2/3 of the tooth surface. Mean interproximal TPI score=Average of TPI values over distal and mesial tooth sites assessed for a participant. Lower score indicated better outcome. Change from Baseline=Value at each indicated timepoint minus Baseline value. Baseline=Day 0. A negative change from Baseline indicated improvement (less plaque accumulation).

Adjusted Mean Change From Baseline in Number of Bleeding Sites at Week 12 (Test Product Versus [vs.] Reference Product)

The number of bleeding sites was calculated using the BI assessment. The BI was assessed for all evaluable surfaces (having two-thirds of the natural tooth surface gradable for the assessment) of the facial and lingual/palatal gingiva, 6 sites per tooth (mesiobuccal, buccal, and distobuccal; mesiolingual/palatal, lingual/palatal, and distolingual/palatal). Evaluable tooth sites were probed, and gingival bleeding was assessed for approximately 30 seconds after probing. The number of bleeding sites for each participant was calculated as the number of evaluable tooth sites with bleeding observed immediately on probing or within 30 seconds of probing. Change from Baseline was calculated by subtracting the Baseline value from the value at Week 12. Baseline was defined as Day 0. A negative change from Baseline indicated improvement in gingival bleeding.
