Interventions and Outcome Measures

Arms

experimental: Scaling and Root Planing (SRP) + Livfresh Dental Gel (LDG)

SRP at Baseline with use of LDG (test dentifrice) for twice daily brushing between study visits.

active comparator: Scaling and Root Planing (SRP) + standard fluoride dentifrice

SRP at Baseline with use of standard fluoride dentifrice (control dentifrice) for twice daily brushing between study visits.

Interventions

SRP + Livfresh Dental Gel

SRP at baseline with use of LDG (test dentifrice) for twice daily brushing between study visits. Scaling and root planing is the physical removal of dental plaque, calculus, and bacterial exotoxins embedded onto the root surface of effected teeth with hand instruments and ultrasonic devices. In addition to scaling and root planing, the participants will use LDG as their primary dentrifice (toothpaste) for the next 6 months. They're instructed to use LDG twice daily with toothbrushing for 2 minutes. LDG in previous studies have been reported to be superior to conventional over-the-counter toothpaste in terms of reducing bacterial plaque and gingival inflammation due to its EDTA (ethylenediaminetetraacetic acid) ingredient. EDTA prevents adhesion of bacterial plaque to teeth.

SRP + standard flouride dentifrice

SRP at baseline with use of standard fluoride dentifrice (control dentifrice) for twice daily brushing between study visits. Scaling and root planing is the physical removal of dental plaque, calculus, and bacterial exotoxins embedded onto the root surface of effected teeth with hand instruments and ultrasonic devices. In addition to scaling and root planing, the participants will use standard fluoride toothpaste (commercial over-the-counter toothpaste) as their primary dentrifice (toothpaste). They're instructed to use standard fluoride toothpaste twice daily with toothbrushing for 2 minutes.

Primary outcome measure

  • Incremental reduction in gingival pocket depth. [ Time Frame: From baseline to 6 months ]
