Transmission routes of 2019-nCoV and controls in dental practice – whitepaper. Peng et al.

(344 words)

​In a recent scientific review paper published in the International Journal of Oral Science, several leading Chinese scientists and clinicians highlight the challenges of managing infection risk in dental practice.

The in-depth article discusses the potential transmission routes of the virus and the impact of airborne, contact, and contaminated surfaces spread.

The article’s contributors provide a graphical illustration of transmission routes and a wide-ranging breakdown of infection control procedures.

Topics covered include

  • patient evaluation;
  • hand hygiene;
  • personal protective equipment (PPI);
  • use of mouth rinses;
  • rubber dam isolation;
  • benefits of anti-retraction handpieces;
  • disinfection of clinical settings; and
  • the management of medical waste.



Dental professionals should be familiar with how 2019-nCoV is spread, how to identify patients with 2019-nCoV infection, and what extra-protective measures should be adopted during the practice, in order to prevent the transmission of 2019-nCoV. Here we recommend the infection control measures that should be followed by dental professionals, particularly considering the fact that aerosols and droplets were considered as the main spread routes of 2019-nCoV. Our recommendations are based on the Guideline for the Diagnosis and Treatment of Novel Coronavirus Pneumonia (the 5th edition) ( 3b09b894ac9b4204a79db5b8912d4440.shtml), the Guideline for the Prevention and Control of Novel Coronavirus Pneumonia in Medical Institutes (the 1st edition) ( 202001/b91fdab7c304431eb082d67847d27e14.shtml), and the Guideline for the Use of Medical Protective Equipment in the Prevention and Control of Novel Coronavirus Pneumonia ( yzygj/s7659/202001/e71c5de925a64eafbe1ce790debab5c6.shtml) released by the National Health Commission of the People’s Republic of China, and the practice experience in West China Hospital of Stomatology related to the outbreak of 2019-nCoV transmission.”
