Abstract : Chronic inhalation of particulate matter can lead to pneumoconiosis, which is a broad groupof lung diseases caused by the inhalation of a variety of organic or inorganic dusts or chemical irritants,usually over a prolonged period of time. Common materials used in dental laboratories include feldspathicporcelains, which are silica and alumina based; glass ceramics composed of quartz, lithium disilicate,phosphor oxide, alumina, and potassium oxide; high noble metals; wax; gypsum (which contains calciumsulfate, plaster of paris and crystalline silica); and denture acrylic composed mainly of methylmethacrylate and benzoyl peroxide. All of these materials, when adjusted or polished, can produceparticulate matter that can pose a respiratory threat when inhaled.
