The human oral microbiota is a complex and dynamic ecosystem essential to maintaining oral and systemic health. Dysbiosis can contribute to a wide range of diseases.
Using a proteomic approach, this study investigates the effects of diode laser, ozonated water, and 0.20% chlorhexidine on oral bacterial populations, highlighting their distinct influence on microbial balance and selectivity toward pathogenic species.

The study was performed using the PocketLaser (88dent, Italy) — a 915 nm diode laser — to evaluate the antimicrobial effects on bovine dentin discs.
.
All treatments significantly reduce pathogens such as Fusobacterium nucleatum and Prevotella oris
Diode laser and ozonated water better preserve commensal species, supporting microbial balance (eubiosis).
Findings suggest the potential clinical use of laser and ozone as effective alternatives or adjuncts to chlorhexidine in oral disinfection and periodontal therapy.
