Purpose: Assess the level of protection provided by the various face shields on the aerosol, assess their fogging ability and handling while working.

Materials Required: Airotor, cavity preparation burs, phantom head, typodont model (api), studds face shields, steel bird protective face shield, OHP face shield, Vega Kavach 3 face shield and fluorescent dye.

Method: Forty typodont mandibular first molar teeth were selected and divided into 4 groups (n = 10). A fluorine dye has been added to water reserve fixed to the typodont unit. Cavity preparation was then performed by a single operator’s using four separate face shields. The filter paper was glued to the operators face, ears, chin and shoulders.

Results: The amount of aerosol produced, fogging and the effect of the weight of the various face shields on the operator’s ergonomics were evaluated. The OHP face shield exhibited maximum aerosol exposure in comparison with other group. The haze was lesser for steel bird and Vega Kavach face protector. However, in terms of weight OHP facial screens were the easiest to use.
