氟利昂是一种氯氟烃类化合物,用加压法较易液化。工业方面利用其从液态变成气态时所产生的低温广泛用作致冷剂及喷雾剂。用于口腔科方面的制品为Provotest,因其喷雾器的内压高故用于本研究的是在氟利昂中混合有使降低其喷雾器内压的配伍剂的冷喷雾剂,称为D.C.X.(牙利冷却剂—X)。 Freon is a chlorofluorocarbon compound that is more liquefied by the pressure method. Industrial use of its liquid from the state into the gas generated when the low temperature widely used as refrigerants and sprays. The product used for stomatology was Provotest due to the high internal pressure of the nebulizer. The cold spray used in this study was a combination of Freon with a compatibilizer to lower the internal pressure of the nebulizer, referred to as DCX Agent-X).
