Shockwave Therapy Efficiently Cures Multispecies Chronic Periodontitis in a Humanized Rat Model.

Area of Science:

• Oral microbiology
• Biomedical engineering
• Periodontology

Background:

• Biofilms are primary etiological factors in prevalent oral diseases like periodontitis and dental caries.
• Current antimicrobial treatments face challenges due to biofilm-induced antibiotic tolerance and resistance.
• Novel strategies are needed for effective biofilm control in periodontal therapy.

Purpose of the Study:

• To investigate the efficacy of shockwaves in managing multispecies oral biofilms derived from periodontitis patients.
• To evaluate shockwave therapy alone and in combination with antimicrobials.
• To explore shockwaves as a novel therapeutic approach for biofilm-associated periodontal disease.

Main Methods:

• Multispecies biofilms were developed from subgingival plaque of 25 chronic periodontitis patients.
• Biofilm analysis included scanning electron microscopy, atomic force microscopy, and biomass quantification.
• A humanized rat model of periodontitis was established and treated with shockwaves and/or antimicrobials.

Main Results:

• Shockwave treatment significantly enhanced the clearance of multispecies oral biofilms when combined with antimicrobials.
• The study demonstrated the potential of shockwaves in disrupting oral biofilm development.
• A humanized rat model showed successful infection establishment and treatment response.

Conclusions:

• Shockwave therapy, particularly in combination with antimicrobials, is effective against multispecies oral biofilms.
• This approach offers a novel strategy for managing biofilm-associated periodontal disease.
• Further research, safety validation, and clinical trials are warranted to establish shockwaves as a clinical tool.
