Summary
Air polishing with glycine powder is a safe and effective method for biofilm removal during dental prophylaxis. It outperforms traditional methods in both supra- and subgingival applications across various probing depths.
Area of Science:
- Dentistry
- Periodontology
- Biomaterials
Background:
- A consensus conference addressed the safety and efficacy of glycine powder in air-powder jet devices for dental prophylaxis.
- The focus was on supra- and subgingival biofilm removal during periodontal maintenance.
Framework:
- The conference evaluated scientific evidence on glycine powder air polishing.
- Key areas included biofilm removal efficacy, safety on tooth structures and soft tissues, and comparison with conventional instruments.
Implementation:
- Glycine powder air polishing demonstrated safety and effectiveness on natural teeth and restorative materials.
- No evidence of soft-tissue abrasion was found with glycine powder air polishing devices.
Implications:
- Glycine powder air polishing is superior to manual and ultrasonic instruments for subgingival biofilm removal at depths of 1-4 mm (standard nozzle).
- At probing depths of 5-9 mm, glycine powder air polishing (subgingival nozzle) is more effective than manual or ultrasonic instrumentation.
- This technology offers a safe and effective alternative for enhanced periodontal care.
