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.
