For human teeth to have a healthy oral environment, all parts of the tooth must develop during appropriate stages of fetal development. Primary (baby) teeth start to form between the sixth and eighth week of prenatal development, and permanent teeth begin to form in the twentieth week. [ 1 ]
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 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 ...
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 ...
Oral or dental maxillofacial radiology is one of nine dental specialties recognized by the American Dental Association. [1] [13]To become an oral and maxillofacial radiologist one must first complete a dental degree and then apply for and complete a postgraduate course of training (usually between 2–4 years in length). [14]
It is currently believed that the periodontal ligament plays an important role in tooth eruption. The first human teeth to appear, the deciduous (primary) teeth (also known as baby or milk teeth), erupt into the mouth from around 6 months until 2 years of age, in a process known as "teething". These teeth are the only ones in the mouth until a ...
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. [8]
Tooth development begins at week 6 in utero, in the oral epithelium. The process is divided into three stages: Initiation; Morphogenesis and; Histogenesis [2]; At the end of week 7 i.u., localised proliferations of cells in the dental laminae form round and oval swellings known as tooth buds, which will eventually develop into mesenchymal cells and surround the enamel organ.
