The appearance and perception of a tooth is the result of a complex interaction of factors such as lighting conditions, translucency, opacity, light scattering, gloss and the human eye and brain. [5] Of these, the intrinsic pigmentation of a tooth is the most influential, [4] which in turn is determined by genetic and natural factors. [6]
Iron overload (also known as haemochromatosis or hemochromatosis) is the abnormal and increased accumulation of total iron in the body, leading to organ damage. [1] The primary mechanism of organ damage is oxidative stress, as elevated intracellular iron levels increase free radical formation via the Fenton reaction.
Symptoms usually appear after a number of years, [5] but may rarely appear within a year. [6] Eye exposure to iron dust can also cause another form of siderosis, "ocular siderosis" or "siderosis bulbi", which can cause eye discoloration, but also eye damage, like cataracts and night blindness. This happens via the corrosive effects of iron. [7] [8]
Iron is a mineral that is crucial for optimal health and well-being. Found naturally in many foods and dietary supplements, it is a key component of hemoglobin, the part of red blood cells ...
In dental enamel, fluorosis causes subsurface porosity or hypomineralizations, which extend toward the dentinal-enamel junction as the condition progresses and the affected teeth become more susceptible to staining. Due to diffusion of exogenous ions (e.g., iron and copper), stains develop into the increasingly and abnormally porous enamel. [7]
H&E stain. Common cancer types that are associated with hypercalcemia of malignancy include: Solid tumor with metastasis via local osteolytic hypercalcemia: which can be due to any tumor that metastasizes to the bone. But common causes include breast cancer, lung cancer, kidney cancer, and myeloma or lymphoma of the bone [22]
Acid erosion is a type of tooth wear.It is defined as the irreversible loss of tooth structure due to chemical dissolution by acids not of bacterial origin. [1] Dental erosion is the most common chronic condition of children ages 5–17, [2] although it is only relatively recently that it has been recognised as a dental health problem. [3]
