Aims. Infectious diseases have always been a major concern for the world population; therefore, particular attention should be paid to any precautions for the prevention of infectious disease transmission. The aim of this study was to compare the aerosol spread created by conventional rotating handpieces and piezosurgery during sinus lift procedures.
Materials and Methods Twelve fresh human cadavers were used for this study. Bilateral osseous windows were created on the lateral wall of the maxillary sinus using either piezosurgery or a conventional high-speed rotary device under copious irrigation with methylene blue mixed saline solution. Aerosol spread was scored by scoring the count of droplets on graph paper placed next to the operating table before each surgical procedure.
Results. Aerosol spread was significantly higher in the piezosurgery group for the first 7 distances (70 cm from the head level), while no significant difference was found at further distances.
Conclusions. The findings of this study suggest that utilizing a conventional rotary handpiece instead of piezosurgery for sinus lifting osteotomies may decrease aerosol spread.
