The tongue lies low in the mouth or oral cavity and is typically forwarded between upper and lower teeth. If tongue thrust behavior is not corrected, it may affect the normal dental development. The teeth may be pushed around in different directions during the growth of permanent teeth.
Tooth pathology is any condition of the teeth that can be congenital or acquired. Sometimes a congenital tooth disease is called a tooth abnormality.These are among the most common diseases in humans [1] The prevention, diagnosis, treatment and rehabilitation of these diseases are the base to the dentistry profession, in which are dentists and dental hygienists, and its sub-specialties, such ...
By targeting the USAG-1 gene, researchers believe that they can help people without a full set of teeth regrow teeth. The team says that humans have a third set of teeth available as buds, ready ...
A medical and dental history is obtained for completeness. The medical history includes questions on the general health of the patient, to assess contraindications to treatment of jaw abnormality. Special emphasis is placed on diseases and medication which cause altered metabolism, that may affect growth and tissue reactions. [19]
Since the formation of enamel extends over a long period of time, defects may be confined to one well-defined area of the affected teeth. Knowledge of chronological development of deciduous and permanent teeth makes it possible to determine the approximate time at which the developmental disturbance occurred. [ 6 ]
Some commonly held theories that have been disproven over time include: (1) the tooth is pushed upward into the mouth by the growth of the tooth's root, (2) the tooth is pushed upward by the growth of the bone around the tooth, (3) the tooth is pushed upward by vascular pressure, and (4) the tooth is pushed upward by the cushioned hammock.

Ultimately, tooth loss may occur if the condition is not halted. It is termed localized when less than 30% of sites around teeth are involved, and generalised when more than 30% are involved. clinical attachment loss can be used to determine the severity of the condition, where 1–2mm is slight, 3–4mm is moderate and more than 5mm is severe.

Dentinogenesis imperfecta affects an estimated 1 in 6,000-8,000 people. [7] This condition can cause teeth to be discolored (most often a blue-gray or yellow-brown color) and translucent, giving teeth an opalescent sheen. [2] [3] [8] [5] [9] Teeth are also weaker than normal, making them prone to rapid wear, breakage, and loss.
