Title : Effect of a novel anti-splash mask on preventing aerosol in dental practice


To evaluate the effect of a new anti-splash mask on preventing aerosol pollution in dental clinics.

The aerosol distribution characteristics in different types of splash operations were analyzed in dental clinics at first. Different splash operations were composed of cavity preparation, tooth preparation, interproximal enamel reduction, and supragingival scaling. Then tooth preparation on isolated teeth was simulated in dental phantom head. According to whether to use the anti-splash mask, experiments were divided into the experimental group and the control group. The droplets of aerosol at multiple time points were sampled before, during, and after dental procedures. The effectiveness of preventing aerosol pollution by the novel anti-splash mask was analyzed.

The aerosol concentrations caused by diverse splash operations in the clinics increased respectively (P<0.05). The aerosol concentration resulting from tooth preparation was the highest (P<0.05). To simulate dental treatment, tooth preparation was performed on isolated teeth in dental phantom head. It was found that the aerosol concentration was significantly decreased when using anti-splash masks (P<0.05).

Diverse dental splash procedures initiated a large amount of aerosol respectively. The use of novel antisplash mask in the process of dental diagnosis and treatment can reduce the aerosol concentration in dental clinics, which have a positive effect on preventing the spread of COVID-19.

Audience take away: 
• Introduce a new anti-splash mask on preventing aerosol pollution in dental clinics developed by our research group, which has been authorized the national invention patent.
• Analyse the effectiveness of preventing aerosol pollution by the novel anti-splash mask.
• Provide ideas and suggestions to further improve the performance of the anti-splash mask according to the requirement on the field of vision.


Dr. Wenmei Wang was admitted to Hubei Medical College (now the School of Stomatology of Wuhan University) to study for a master's degree in 1987, and graduated in 1990 with a master's degree in stomatology. She is now a professor, master tutor at the Medical School of Nanjing University and medical supervisor at the Nanjing Stomatological Hospital. She is mainly engaged in the diagnosis and treatment of oral mucosal diseases, scientific research and teaching, and has rich experience in the diagnosis and treatment of rare diseases related to oral mucosa. Combined with clinical research work, she presided over and completed more than 10 projects at various levels, published more than 200 papers, translations and reviews in SCI and core journals, and participated in the editing of 8 books.
