Clinical and microbiological effects of commercially available dentifrice containing amine fluoride: A randomized controlled clinical trial

Abstract

Background: The inability of the normal adult population to perform adequate tooth brushing has led to the search for chemotherapeutic agents in order to improve plaque control. This 6 month, single center, randomized controlled clinical trial was conducted to assess the clinical and microbiological effects of a dentifrice containing only amine fluoride (AF) as the active ingredient on gingivitis. Materials and Methods: Ninety subjects diagnosed with chronic generalized gingivitis were selected and randomly divided in three groups: Group 1 - placebo toothpaste, Group 2 - AF containing toothpaste, and Group 3 - triclosan containing toothpaste with polymer and fluoride. Clinical evaluation was undertaken using the gingival index of Loe and Silness and the plaque index and microbiological counts were assessed at baseline, 6 weeks, 12 weeks, and 24 weeks. A subjective evaluation was also undertaken by a questionnaire. Results: AF containing toothpaste showed significant improvement in gingival and plaque index scores as well as microbiologic counts compared with placebo dentifrice. These improvements were comparable to triclosan containing toothpaste. Conclusions: AF containing toothpaste may be a useful formulation for chemical plaque control agent and improvement in plaque and gingival status and add to the list of various therapeutic agents used for maintenance of gingival health.
