Effect of microbubbled water on the removal of a biofilm attached to orthodontic appliances--an in vitro study

Orthodontic appliances often lead to oral health issues, such as dental caries and gingivitis, due to biofilm accumulation. However, effective methods to remove biofilm from these appliances are limited. This study evaluated the impact of microbubbled water on the removal of biofilms formed by Streptococcus mutans and Candida albicans on orthodontic appliances. Appliances with biofilm were immersed in microbubbled water, and residual biofilm was quantified using a micro-plate reader and absorbance measurements. Microbubbled water proved significantly more effective than tap water in biofilm removal (for S. mutans: p<0.05, and for C. albicans: p<0.01). These findings indicate that microbubbled water could be a useful tool for biofilm management in orthodontic patients.

An experiment was conducted to evaluate the effectiveness of removing oral bacteria using various design variables, including a three-segment rotor speed in the testing device and three types of stainless steel meshes with different layer configurations.

Results indicated up to 95% bacteria removal, with some configurations achieving a full 100% hygienic effect. The study suggested that nanobubbles, generated through a high-density stainless-steel mesh nozzle, effectively eliminate dental bacteria. Additionally, the device has potential applications in auxiliary oral hygiene, potentially reducing the need for frequent dental visits due to periodontal issues and providing a convenient hygiene solution for patients with severe periodontal disease.tudy on oral hygiene by nanobubbles from high-density nozzle
