Dental radiographs, commonly known as X-rays, are radiographs used to diagnose hidden dental structures, malignant or benign masses, bone loss, and cavities.. A radiographic image is formed by a controlled burst of X-ray radiation which penetrates oral structures at different levels, depending on varying anatomical densities, before striking the film or sensor.
The other dominant hypothesis, the "clone model", proposes that the epithelium programs a group of ectomesenchymal cells to generate teeth of particular shapes. This group of cells, called a clone, coaxes the dental lamina into tooth development, causing a tooth bud to form. Growth of the dental lamina continues in an area called the "progress ...
The dental lamina is a band of tissue in the developing oral cavity that gives rise to tooth buds. Hyperactivity of the dental lamina, as well as disruption of the differentiation and morphogenesis stages of tooth development, can lead to the formation of extra tooth buds, which can develop into supernumerary teeth.

The dental papilla contains cells that develop into odontoblasts, which are dentin-forming cells. [3] Additionally, the junction between the dental papilla and inner enamel epithelium determines the crown shape of a tooth. [2] The dental follicle gives rise to three important entities: cementoblasts, osteoblasts, and fibroblasts. Cementoblasts ...
Once the first permanent tooth erupts into the mouth, the teeth that are visible are in the mixed (or transitional) dentition stage. After the last primary tooth is shed or exfoliates out of the mouth, the teeth are in the permanent dentition stage. Each patient should be assigned a dentition period to allow for effective dental treatment. [10]
The nation's largest dental association said Thursday it will no longer recommend the use of lead aprons and thyroid collars on patients who are getting dental X-rays. There are two main reasons ...
However, the teeth are not more susceptible to dental caries than normal ones. Periodontal disease, or gum disease, is a common finding amongst individuals with dentinogenesis imperfecta despite no clinical findings of tooth decay (dental caries). The reason for this is currently not well understood. [3]
