In the generalized form, all teeth are involved. In the localized form, only a few teeth are involved. The most common teeth affected are the upper lateral incisors and third molars. Teeth affected by microdontia may also have abnormal shape, and the abnormal size may affect the whole tooth, or only a part of the tooth. [1]
Teeth displaying enamel hypoplasia lines, linear defects of enamel that form during crowns development as a result of periods of nutritional stress or disease during infancy and childhood 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.
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.
Teeth affected by regional odontodysplasia nevAmelogenesis imperfecta is an autosomal dominant disease characterized by a defect in dental enamel formation. Teeth are often free of enamel, small, misshapen, and tinted brown. The cause of these deformities is due to a mutation in enamel in expression.
Micrognathism is a condition where the jaw is undersized. It is also sometimes called mandibular hypoplasia. [2] It is common in infants, [3] [4] but is usually self-corrected during growth, due to the jaws' increasing in size.
Sometimes, only a couple of ameloblasts stop forming enamel, leading to small PEH defects, with large pits forming when hundreds of these enamel-forming cells stop production. [6] This does not occur in other forms of enamel hypoplasia, such as linear and plane-form , in which all ameloblast activity is affected. [ 4 ]
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]
There is a high prevalence of children with missing permanent teeth in West Virginia compared to the rest of the nation. During this study, 500 panoramic images were taken of children between the ages of 6 and 11. Out of the 500 images taken, 60 children had at least one or more missing permanent teeth.
