The study initially aimed to measure droplets; however, as more was learned about COVID transmission, it became apparent that aerosol should be measured, but the method to measure aerosol was not possible for this study, so the study was withdrawn.

The purpose of this study is to collect, measure, and assess the environmental spatter produced during dental appointments under different isolation methods used in pediatric dentistry, to compare the effectiveness of aerosol reduction between these methods, to identify the most effective way to manage aerosol during dental prophylaxis for pediatric patients and to provide clinical evidence to facilitate practice guidelines in dentistry related to COVID-19.
