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 ]
These teeth are very brittle. On radiographs the teeth appear more radiolucent than normal, so they are often described as "ghost teeth". [1] Most cases are considered idiopathic, but some cases are associated with syndromes, growth abnormalities, neural disorders, and vascular malformations. Permanent teeth usually show effects of regional ...
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 ...
Gingival recession, also known as gum recession and receding gums, is the exposure in the roots of the teeth caused by a loss of gum tissue and/or retraction of the gingival margin from the crown of the teeth. [1] Gum recession is a common problem in adults over the age of 40, but it may also occur starting in adolescence, or around the age of 10.
[13] [14] Globally, 538 million people were estimated to be affected in 2015 and has been known to affect 10–15% of the population generally. [7] [8] [6] In the United States, nearly half of those over the age of 30 are affected to some degree and about 70% of those over 65 have the condition.

Hyperactivity or overgrowth of dental lamina can give rise to conditions such as Hyperdontia. Having this condition means patients have supernumerary teeth - additional teeth other than 20 primary teeth in children and 32 permanent teeth in adults. The reasons for this condition could be any of the following: Dichotomy (division) of tooth buds.
