Scientists from Kaunas University of Technology (KTU) and other Lithuanian institutions have developed groundbreaking dental equipment designed to eliminate viruses during treatment. Utilizing High-Intensity Narrow-Spectrum (HINS) ultraviolet rays, these innovations improve the safety of dental professionals by minimizing the risk of infection without interrupting patient care.

One of the key inventions is an advanced air purifier that disinfects exhaled air from patients. The air passes through multiple filters and is exposed to HINS rays, destroying virus cells before releasing clean air back into the environment. The design ensures that the suction pipe is placed 20 centimeters from the patient’s face, allowing healthcare professionals to work without interference.

Another innovation is a transparent protective shield that separates the patient from the dental professional. This shield is equipped with UV lamps that disinfect any virus particles settling on its surface. The protective barrier enables dentists to perform procedures like plaque and tartar removal safely, reducing the risk of viral transmission.

The third invention addresses the disinfection of dental fluids. Saliva and other liquids collected during dental treatments are disinfected before they enter the sewage system, ensuring no viruses are released into the environment. HINS light sources integrated into the module destroy virus cells effectively, making the equipment crucial for maintaining a sterile clinical environment.

Tested extensively by dental specialists, these innovations have been validated using PCR molecular methods. .
