Aims Infectious diseases have been always a major concern for world population; therefore, particular attention should be paid on any precautions for prevention of infectious disease transmission. The aim of this study was to compare the aerosol spread created by conventional rotating handpiece and piezosurgery during sinus lift procedure.
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 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 papers placed next to the operating table before each surgical procedure.
Results Aerosol spread was significantly higher in piezosurgery group for the first 7 distances (70 cm from the head level), while no significant difference was found in further distances.
Conclusions The findings of this study suggest that utilizing conventional rotary handpiece instead of piezosurgery for sinus lifting osteotomy may provide benefit in decreasing aerosol spread.
