Full trisomy 9 is a rare and fatal chromosomal disorder caused by having three copies of chromosome number 9.It can be a viable condition if the trisomic component affects only part of the cells of the body or in cases of partial trisomy of the short arm (trisomy 9p) in which cells have a normal set of two entire chromosomes 9 plus part of a third copy of the short arm ("p") of the chromosome.
Turner's hypoplasia or Turner's tooth is a presentation of enamel hypoplasia that normally affects only a single tooth. Its causes can be the same as other forms of enamel hypoplasia, but it is most commonly associated with trauma to a primary maxillary central incisor and the subsequent developmental disturbance of the underlying permanent ...
The number of chromosomes in the cell where trisomy occurs is represented as, for example, 2n+1 if one chromosome shows trisomy, 2n+1+1 if two show trisomy, etc. [2] "Full trisomy", also called "primary trisomy", [2] means that an entire extra chromosome has been copied. "Partial trisomy" means that there is an extra copy of part of a chromosome.

One of the most common types, pitting enamel hypoplasia (PEH), ranges from small circular pinpricks to larger irregular depressions. [2] Pits also vary in how they occur on a tooth surface, some forming rows and others more randomly scattered. [3] PEH can be associated with other types of hypoplasia, but it is often the only defect observed. [4]
The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child.
Patients diagnosed with anodontia are expected to have a normal life expectancy. Once anodontia is diagnosed, dental implants or dentures will need to be worn in order to treat this disorder. There is an 88.5% to 100% chance for dental implants in patients with ectodermal dysplasia or tooth agenesis to be successful when placed after the age of 18.
] It is the most common type of enamel hypoplasia reported in clinical and archaeological samples, with other types including plane-form enamel hypoplasia and pitting enamel hypoplasia. [12] Linear enamel hypoplasia can be caused by a variety of factors, from genetic conditions to malnutrition and illnesses during childhood.
