RCT: Enzyme Blend Toothpaste on Dental Biofilm Plaque Accumulation

Study Summary

The aim of the study is to investigate whether brushing twice a day with a toothpaste (Biofresh Clean) containing a blend of alpha-amylase and gluco-amylase improves oral health outcomes over a 14-day period. The primary objective is to evaluate if the enzyme-containing toothpaste has an effect on dental plaque accumulation compared to placebo following 28 days of use. The secondary objectives are to: * Evaluate if the enzyme-containing toothpaste has an effect on dental plaque accumulation compared to placebo at Days 1 and 14 * Evaluate if the enzyme-containing toothpaste has an effect on gumline and proximal plaque severity compared to placebo at Days 1, 14 and 28 * Evaluate if the enzyme-containing toothpaste has an effect on whole mouth Gingivitis as well as gumline and proximal Gingivitis severity compared to placebo at Days 14 and 28 The exploratory variables are to investigate if the enzyme-containing toothpaste results in: * Shift in detected oral bacterial species of interest at Screening and Baseline to Days 14 and 28, based on microbial DNA-extraction and microbial whole genome sequencing compared to placebo. * Shift in immune markers (IL-1β, , IL-8 and MIF) at Screening and Baseline to Days 14 and 28, based on electrochemiluminescence assay compared to placebo. * Difference in performance attributes compared to placebo based on End of Study Post-product use questionnaire after 28 days of product use. The safety objective is to investigate safety and tolerability of brushing twice daily based on treatment emergent adverse events. Target Population Randomized subjects are generally healthy males and females (18-65y) with at least 20 natural teeth, A gingival index score of ≥ 1.0, according to the Löe-Silness Gingival Index at baseline and a plaque index score ≥ 1.95 according to the Lobene-Soparkar Modification of the Turesky Modification of the Quigley-Hein Plaque Index.. Researchers will compare Biofresh Clean Toothpaste to an identically package

Primary Outcome

Change in mean whole Mouth (WM) dental plaque accumulation assessed using the Lobene-Soparkar Modification of the Turesky Modification of the Quigley-Hein Plaque Index (PLI) with a score range from 0 to 5. A score of 0 means no plaque, while higher scores indicate increasing amounts of plaque.
