Failure to completely clean out the necrotic soft tissue of the pulp system may cause staining, and certain root canal materials (e.g., gutta percha and root canal sealer cements) can also. [1] Another possible factor is the lack of pulp pressure in dentinal tubules once the pulp is removed, leading to incorporation of dietary stains in dentin.
Intravenous iron infusions can cause skin rash, hives, itchiness and flush. Skin staining and discolouration can occur at the site of infusion if the iron and saline solution leaks outside the vein into the surrounding tissue. [14] Skin discolouration can be semi-permanent or permanent.
It is this breakdown of heme that is the source of iron deposition that ultimately causes superficial siderosis. [6] The excess free iron is circulated in the cerebrospinal fluid and deposited in neuronal tissues, where it catalyzes the formation of reactive oxygen species which can damage DNA, lipids and proteins, and is otherwise toxic to the ...
The perception of tooth colour is multi-factorial. Reflection and absorption of light by the tooth can be influenced by a number of factors including specular transmission of light through the tooth; specular reflection at the surface; diffuse light reflection at the surface; absorption and scattering of light within the dental tissues; enamel mineral content; enamel thickness; dentine colour ...
Based on the most common causes of toothache (dentin hypersensitivity, periodontitis, and pulpitis), the key indicators become localization of the pain (whether the pain is perceived as originating in a specific tooth), thermal sensitivity, pain on biting, spontaneity of the pain, and factors that make the pain worse.
Iron isomaltoside 1000 (brand name Monofer) is a formulation of parenteral iron that has a matrix structure that results in very low levels of free iron and labile iron. It can be given at high doses – 20 mg/kg in a single visit – no upper dose limit. This formulation has the benefit of giving a full iron correction in a single visit. [64] [63]
Tyramine is an amino acid found in some foods and can be part of a chain reaction that leads blood vessels in the head to narrow and dilate, which causes throbbing pain, according to the National ...
Gingival recession and cervical tooth wear are a few of the main causes of dentine hypersensitivity, as they lead to the exposure of dentinal tubules. This can be avoided by healthy dietary and oral hygiene practices. Using a non-traumatic toothbrushing technique (i.e. a recommended technique such as the modified Bass technique rather than ...
