Turner's hypoplasia or Turner's tooth is a presentation of enamel hypoplasia that normally affects only a single tooth. Its causes can be the same as other forms of enamel hypoplasia, but it is most commonly associated with trauma to a primary maxillary central incisor and the subsequent developmental disturbance of the underlying permanent ...
Enamel hypoplasia is a developmental defect of enamel that occurs during tooth development, mainly pre-natal or during early childhood. Teeth affected by enamel hypoplasia are at a higher risk of caries since there is an increased loss of minerals and therefore the tooth surface is able to breakdown more easily in comparison to a non ...
Pitting enamel hypoplasia, in an individual with amelogenesis imperfecta. It is not always clear why PEH forms instead of other hypoplasia types, particularly linear enamel hypoplasia . However, the position on the crown, the tooth type and the cause of the disruption are all likely contributing factors.
It is the longest tooth in total length (from the root to the incisal edge) in the mouth. Canines are also the only anterior teeth with a cusp. Maxillary canines begin to calcify by 4 months of age. The enamel of the tooth is completely formed by around 6 to 7 years of age and the permanent maxillary canines erupt at around 11 to 12 years of age.
Typically, all baby teeth will be present by the age of three. As for all adult teeth, they erupt between the ages 6 to 14, with the exception of the third molar, also known as the wisdom teeth which normally erupt between 17 and 25 years of age. If the tooth has yet to erupt by an appropriate age, panoramic x-rays are taken.
Enamel appears to be comparable to dentine in its radiodensity on radiographs. Type 3 - Hypocalcified Enamel defect due to malfunction of enamel calcification, therefore enamel is of normal thickness but is extremely brittle, with an opaque/chalky presentation. Teeth are prone to staining and rapid wear, exposing dentine.
[3] [11] Dogs suffering systemic manifestations of the disorder often have poorer prognoses. Systemic manifestations include fever, multiple body organ inflammation, nasal (nose) and ocular (eye) discharge, diarrhea, hyperkeratosis of the foot pads, pneumonia, and tooth enamel hypoplasia (many of these symptoms overlap with symptoms of CDV).
