A Study to Measure the Effect of a Toothpaste Containing Proteins and Enzymes and a Fluoride Toothpaste on Gingival Health

This study is a double-blind, randomised, parallel group efficacy study. A minimum of 240 healthy female and male participants aged 18-70 years will be enrolled onto the study according to the inclusion/exclusion criteria. The accepted participants will then be randomly allocated to one of the two test products which they will use at home, twice a day for the duration of the study. Dental assessments of gingival condition and plaque level will be conducted after 4, 13 and 26 weeks of product use at the study site.

Inclusion Criteria:

• Be willing and physically able to carry out all study procedures.
• Be willing and competent (verbally and cognitively) to give written informed consent and complete a medical history form.
• Have at least 20 natural teeth without subgingival calculus including 5 teeth (excluding 3rd molars) in each quadrant, which can be assessed.
• Have mean Gingival Index (GI) score between 1.0 and 2.0 (1.0 ≤ Mean GI ≤ 2.0) and mean Plaque Index (PI) ≥ 1.5 at screening and baseline.
• Not have had a scale and prophylaxis in the month prior to enrolment or have one scheduled prior to the end of the study.
• Be willing to use only the test products for 6 months, after brushing with the products on site.
• Brush teeth twice daily (once in the morning and once at night).

Exclusion Criteria:

• Pregnant or breast feeding mothers.

• Current participation in any other cosmetic trials, any dental clinical trials or clinical trials.
• Subjects who have used gum health products in the 4 weeks prior to screening.

• Full or partial dentures wearers.
• Current orthodontic treatment.
• Smokers or those who have a recent smoking history, including e-cigarettes.
• Diabetics.
• Medical condition and/or regular use of any medication which might affect the outcome of the study, as determined by the study dentist, principally a course of anti-inflammatory, antimicrobial or statin drugs within 4 weeks of screening.
