Illnesses arise long after exposure: asbestos related diseases can arise decades after actual exposure. Asbestos industry alleged misconduct: alleged concealing, distorting, and suppressing of risk related information, by asbestos related businesses. As of 1999, trends indicate that the worldwide rate at which people are diagnosed with asbestos ...
Chlorhexidine (antiseptic mouthwash) binds to tannins, meaning that prolonged use in persons who consume coffee, tea or red wine is associated with extrinsic staining (i.e., removable staining) of teeth. [14] Cetylpyridinium chloride, which is found in many antimicrobial mouthwashes, can result in staining due to dead bacterial residue. [15] [16]
Asbestos (/ æ s ˈ b ɛ s t ə s, æ z-,-t ɒ s / ass-BES-təs, az-, -toss) [1] is a group of naturally occurring, toxic, carcinogenic and fibrous silicate minerals.There are six types, all of which are composed of long and thin fibrous crystals, each fibre (particulate with length substantially greater than width) [2] being composed of many microscopic "fibrils" that can be released into ...
Asbestos-related diseases are disorders of the lung and pleura caused by the inhalation of asbestos fibres. Asbestos-related diseases include non-malignant disorders such as asbestosis (pulmonary fibrosis due to asbestos), diffuse pleural thickening, pleural plaques, pleural effusion, rounded atelectasis and malignancies such as lung cancer and malignant mesothelioma.
Tooth discolouration and staining is primarily due to two sources of stain: intrinsic and extrinsic (see Figure 2). [1] In essence, tooth whitening primarily targets those intrinsic stains in which cannot be removed through mechanics such as a debridement (clean) or prophylaxis , in the dental office. [ 6 ]
Dental fluorosis is caused by a higher than normal amount of fluoride ingestion whilst teeth are forming. Primary dentine fluorosis and enamel fluorosis can only happen during tooth formation, so fluoride exposure occurs in childhood. Enamel fluorosis has a white opaque appearance which is due to the surface of the enamel being hypomineralised ...
(Reuters) -A state judge in Oregon has overturned a jury's $260 million verdict against Johnson & Johnson in a lawsuit brought by a woman who said she got mesothelioma, a deadly cancer linked to ...
The purpose of polishing is to remove extrinsic stains, remove dental plaque accumulation, increase aesthetics and to reduce corrosion of metallic restorations. [ 1 ] [ 2 ] Tooth polishing has little therapeutic value and is usually done as a cosmetic procedure after debridement and before fluoride application. [ 3 ]
