Primary Outcome Measures:
  • Reduction in gingivitis [ Time Frame: 6 months ]
    To proof whether rinsing with ASF adjunctive to mechanical oral hygiene is more effective on gingivitis reduction than mechanical oral hygiene alone.

Secondary Outcome Measures:
  • Reduction in plaque [ Time Frame: 6 months ]
    To proof whether rinsing with ASF adjunctive to mechanical oral hygiene is more effective on plaque reduction than mechanical oral hygiene alone.

  • Discoloration of teeth [ Time Frame: 6 months ]
    To proof the effect of rinsing with ASF on discoloration of teeth

  • Bacterial colonization [ Time Frame: 6 months ]
    To proof whether rinsing with ASF adjunctive to mechanical oral hygiene influences bacterial colonization

  • Adverse events [ Time Frame: 6 months ]
    Recording all adverse events over the entire rinsing period

Enrollment: 180
Study Start Date: November 2010
Study Completion Date: January 2012
Primary Completion Date: January 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: amine fluoride/stannous fluoride
Amine fluoride/stannous fluoride mouthrinse in addition to mechanical oral hygiene
Drug: amine fluoride/stannous fluoride
10 ml qd, oral, topical, 6 months duration
Other Name: meridol
No Intervention: No rinsing
Mechanical oral hygiene only

Detailed Description:
Gingivitis prevalence is 100% among the population. This is mostly due to an inadequate mechanical cleaning of the teeth. However, remaining dental biofilm can be approached by antibacterial mouthrinses. As a consequence of regular use of these mouthrinses, gingivitis can be reduced. Amine fluoride/stannous flouride mouthrinse (ASF)has proved its efficacy in several studies. In the previous years, a new formulation that does not contain ethanol anymore was introduced in the market. Therefore, it is the aim of the study to proof whether rinsing with ASF adjunctive to mechanical oral hygiene is more effective on gingivitis reduction than mechanical oral hygiene alone. In addition, effects on dental plaque, discoloration of teeth and bacterial colonization should be studied.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Healthy male and female adults aged ≥18 years.
  • Participants who have gingivitis/mild chronic periodontitis (approximal probing depth ≤ 3.5 mm at ≥ 80 % of the sites and at ≤ 20 % of the sites > 3.5 mm and < 5 mm).
  • Participants must have read, understood and signed the informed consent form.
  • Participants who have a GI ≥ 1.3 at baseline.
  • Participants who have at least 20 own teeth excluding the wisdom teeth (incl. 16 natural crowns).
  • Participants who have an acceptable compliance according to the investigators' assessment.

Exclusion Criteria:

  • Participants who have systemic diseases that require regular systemic medication intake that may affect the gingival condition (e. g. phenytoin, nifedipine, cyclosporine, antibiotics, steroids, antiphlogistics).
  • Participants who require antibiotic treatments for dental appointments (endocarditis prophylaxis).
  • Participants who were treated with antibiotics 8 weeks before recruitment and during the course of the study.
  • Participants who were treated with any antibacterial mouthrinse 6 weeks before recruitment.
  • Participants who use other than the recommended mouthrinse or toothpaste during the study period.
  • Participants who have moderate and severe chronic or aggressive periodontitis.
  • Participants who have irregularities of the gingival tissues, e. g. hyperplastic gingiva, mucosal diseases.
  • Participants who have rampant caries.
  • Participants under guardianship or without freedom by administrative or legal award.
  • Known hypersensitivity or allergy to the study product and standard toothpaste ingredients used in the present study.
  • Known pregnancy or breast feeding during the course of the study.
  • Participation in another clinical trial or receipt of an investigational compound/treatment at the same time and 4 weeks prior to inclusion.
