The sink is usually not involved in patient-to-patient spread of microbes as it is not directly in contact with the patient or their oral cavity. However, it still requires regular cleaning and disinfection to prevent the accumulation and spread of microbes in the dental office. The other surfaces listed (air/water syringe handle, curing light handle, and handpiece control switch) are all in direct contact with the patient and their oral cavity, and therefore pose a higher risk for patient-to-patient transmission of microbes.
