ABSTRACT:
An oral screening tool for use in dentistry consists of an elastic sheet pressed on three sides by an elastic two-way aspirating frame fitted to a central exhaust which includes at least one aspirator for local suction purpose. The sheet is centrally held by the tooth and, owing to its elastic nature, forms a cavity for the collection of liquids. Use of a flexible frame allows adjustment of its shape, access to the oral cavity and does not hinder breathing. The tool can be handled by a single operator and automatically performs liquid elimination.
