Last update date: 2020-05-12 00:09In the past few months, the new type of coronary pneumonia has been affected by many industries. Among them, dental treatment involves high-risk procedures, severe outbreaks and insufficient equipment, and some clinics have been closed. Earlier, a person diagnosed with a new coronavirus pneumonia had consulted a dentist after the onset of illness. Fortunately, the clinic staff and other patients were not affected.
A professor at the School of Dentistry of the University of Hong Kong said that some dental treatments are at higher risk. Some private dentists said that 60% of patients canceled their appointments due to the epidemic.

"Splashing water" appears after washing teeth
Zhang Shunbin, a clinical professor in the Department of Endodontics of the Hong Kong University of Dental Medicine, said in an interview that according to his knowledge, the staff and patients of the relevant dental clinics were not infected. In fact, since 2000, local dentists have established high-standard infection prevention procedures in accordance with the guidelines of the Infection Control Office of the Department of Health to effectively protect medical staff and patients.
Dental treatment involves a number of high-risk care procedures such as atomization, and it is difficult to purchase disposable defense supplies. Many dental clinics are temporarily closed for business. Zhang Shunbin pointed out that some dental treatment methods need to be cleaned with a high-speed water column after the patient opens the mouth, which will cause "water splashing", which has a higher risk to dentists and nurses, and has been suspended. "And the family will do ultrasound treatment. 1. Tooth washing is the same as car washing (tooth preparation). Chichi will return first. "The patient is also reluctant. Zhang Shunbin quoted some private dentists as saying that many patients canceled their dental appointments because of concerns about infections. On average, six adults cancel.

The old method of removing calculus: using a spatula
The current epidemic is relatively mild, and some dental treatments have been restored. The teeth cleaning treatment is temporarily removed by the most traditional method, that is, using a spatula to remove calculus. I believe it is safe to go home for treatment! "
He mentioned that the local dentists have already adopted the infection control guidelines of the Internationally Recognized Infection Control Office, which has certain protection for the personnel and patients responsible for the treatment. The dentists and nurses will wear protective clothing, masks and face masks. Wait, must be disinfected after each use, and covered with protective film.
