Causal factors may occur locally, affecting only a single tooth, or they may act systemically, affecting all teeth in which enamel is being formed. Local trauma or abscess formation can adversely affect the ameloblasts overlying a developing crown, resulting in enamel hypocalcification or hypoplasia. Affected teeth may have areas of coronal ...
Enamel hypoplasia is a risk factor for dental caries in children including early childhood caries (ECC), which continues to be a burden for many children. This association has been identified as significant and independent, and is believed that the formation of pits and missing enamel provides a suitable local environment for adhesion and ...
Molar incisor hypomineralisation (MIH) is a type of enamel defect affecting, as the name suggests, the first molars and incisors in the permanent dentition. [1] MIH is considered a worldwide problem with a global prevalence of 12.9% and is usually identified in children under 10 years old. [2]
] It is the most common type of enamel hypoplasia reported in clinical and archaeological samples, with other types including plane-form enamel hypoplasia and pitting enamel hypoplasia. [12] Linear enamel hypoplasia can be caused by a variety of factors, from genetic conditions to malnutrition and illnesses during childhood.
Fluorosis does not cause discolouration to the enamel directly, as upon eruption into the mouth, affected permanent teeth are not discoloured yet. 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 ...
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.
Enamel hypoplasia and enamel hypocalcification are examples of defective enamel that potentially gives a discolored appearance to the tooth. 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 ...
