Multiwave Locked System Laser Treatment Reduces the Bacterial Load in the Gingival Sulcus of Dogs After Plaque Removal

The prevention and control of periodontal diseases in dogs can become challenging in the absence of veterinary intervention if the requested home-based daily care is not guaranteed. To evaluate the eventual efficacy of Multiwave Locked System (MLS) laser application in conjunction with the standard plaque removal procedure, in this study, the comparative analysis of mesophilic oral bacteria via gingival swabs in sixteen dogs was executed. The laser application resulted in a 1-log reduction in bacteria counts and no significant differences in bacteria species isolated from gingival swabs. The MLS laser application was found to be effective in 80% of subjects (p < 0.05), demonstrating its potential as a valuable tool in the prevention of periodontal disease, particularly given its simplicity and non-invasive nature.
