The pits, bands, and loss of areas of enamel seen in severe fluorosis are the result of damage to the severely hypomineralized, brittle and fragile enamel which occurs after they erupt into the mouth. [12] Hydroxyapatite is converted to fluorapatite in a three step process.
Teeth affected in this way are also usually more susceptible to further staining acquired throughout life. Amelogenesis imperfecta is a rare condition that affects the formation of enamel (amelogenesis). The enamel is fragile, the teeth appear yellow or brown, and surface stains build up more readily. [1]
There is no predilection for race, but females are more likely to get regional odontodysplasia. The enamel, dentin, and pulp of teeth are affected, to the extent that the affected teeth do not develop properly. These teeth are very brittle. On radiographs the teeth appear more radiolucent than normal, so they are often described as "ghost teeth ...
These teeth are typically worn, because they were frequently moved and redeposited in different areas repeatedly before settling down. Other locations, however, yield perfect teeth that were hardly moved during the ages. These teeth are typically fragile, and great care should be taken while excavating them. [16]
Endocrowns are especially indicated in cases of molar teeth with short, or fragile roots. They may also be used in situations of excessive loss of coronal dental tissue. Reinforced, acid-etchable dental ceramics have been the materials of choice for the fabrication of endocrowns because they guarantee the mechanical strength needed to withstand the forces exerted on the tooth, as well as the ...
Teeth can break when you inadvertently bite on an unpopped kernel, says Dr. Kenneth Magid, D.D.S., founder of Advanced Dentistry of Westchester in New York. Plus, he says the husks of corn are the ...
The teeth can also look normal in color, but also have a physical impression of extreme fragility and thinness in appearance. Additionally, severe underbites where the top and bottom teeth fail to correctly align may be present; it is common for the affected individual to have a larger, more pronounced lower jaw and longer bones.
Primary teeth have a more obvious appearance as they have a thinner layer of enamel overlying dentine, hence the abnormal color of dentine is more noticeable. [2] Radiographically, affected teeth have short and narrow roots, and obliterated pulps due to dentine hypertrophy before or shortly after tooth eruption. [2]
