Analysis of damage on the Streptococcus mutans immersed in ozonated water: preliminary study for application as mouth rinse
Ozonated water has been demonstrated to induce significant results in terms of the elimination ofmicroorganisms. The present study assessed the damage toStreptococcusmutansafter exposureto ozonated water; the ozone generator was adjusted to provide an outlet concentration of60 mg/L, the samples were submitted to different ozonation times 1, 2, 4, 6, and 10 mi. Scanningelectron microscopy and atomic force images were obtained to identify damage to the bacteria,followed by reactive oxygen species (ROS) evaluation and microbial viability. The results showed asignificant reduction in viability and the images evidenced the generation of gaps on themicrobial wall and surface layer alterations. Ozone can induce significant damage toS.mutans,thus suggesting that the use of ozonated water to prevent carious lesion formation is extremelypromising.
