Introduction:
Ultrasonic scaling has transformed periodontal therapy, delivering effective plaque and calculus removal. However, it also introduces risks through the generation of aerosols and splatter, which can transmit infectious agents. This review evaluates strategies to mitigate aerosol contamination in modern dental practice.
Results:
Pre-, intra-, and post procedural measures can significantly minimize contamination. Adequate ventilation, appropriate coolant selection, and preprocedural mouthrinses limit aerosol generation. Personal protective equipment reduces exposure, while high-volume evacuators (HVEs) effectively capture aerosols. After the procedure, thorough instrument reprocessing and surface disinfection, along with the use of high-efficiency particulate air filters (HEPA) and UV irradiation, are essential for air decontamination.
Conclusion:
Ongoing research continues to enhance control protocols. Implementing these measures effectively safeguards both patients and dental personnel, particularly in light of respiratory infections such as flu.
