[Gingival hyperpigmentation caused by dental restorations: the mechanism of detoxification using selenium].
X-ray microanalysis and electron diffraction made on granular metallic deposits of the gingival lamina propria, inducing partial periodontal tattoos, demonstrated that these deposits consisted of crystalline particles combining silver, sulphur and selenium. The role of selenium precipitating of silver and other metals as well as its role in detoxication are discussed.
