Problem Statement

Dental plaque, gingivitis, and caries are caused by complex microbial communities in the mouth. Regular toothpastes focus on mechanical cleaning and chemical antibacterial agents, but they might not always be effective against all harmful microorganisms and biofilms. This calls for innovative technologies that:

more efficiently reduce bacterial load
disrupt biofilm formation
are safe for prolonged use

Active oxygen technology (like reactive oxygen species, ROS) is being explored as an alternative due to its antimicrobial properties.

Study (Research)

The study involves a clinical comparison of four toothpastes regarding:

anti-plaque effectiveness
reduction of gingivitis
impact on caries-related and periodontal microorganisms

Methodology

Clinical study conducted (April – June 2002)
Measurements of plaque index, gingivitis, and microbiological parameters
Comparison between various formulations, including those with active oxygen

Key Scientific Principle

Active oxygen technology operates through reactive oxygen species (ROS) such as:

peroxide compounds
free radicals

These substances cause:

oxidative damage to bacterial cell membranes
disturbance of enzymatic processes
breakdown of biofilms

Results (General Interpretation)

The study suggests that toothpastes containing active oxygen:

can significantly reduce plaque and gingivitis
are effective against both aerobic and anaerobic bacteria
can disrupt biofilm structures

Effectiveness depends on:

concentration of active ingredients
formulation stability
duration of contact in the mouth
