Dentin dysplasia, coronal

Prevalence estimates on Rare Medical Network websites are calculated based on data available from numerous sources, including US and European government statistics, the NIH, Orphanet, and published epidemiologic studies. Rare disease population data is recognized to be highly variable, and based on a wide variety of source data and methodologies, so the prevalence data on this site should be assumed to be estimated and cannot be considered to be absolutely correct.

Autosomal dominant A pathogenic variant in only one gene copy in each cell is sufficient to cause an autosomal dominant disease.


Autosomal recessive Pathogenic variants in both copies of each gene of the chromosome are needed to cause an autosomal recessive disease and observe the mutant phenotype.


dominant X-linked dominant inheritance, sometimes referred to as X-linked dominance, is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome.


recessive Pathogenic variants in both copies of a gene on the X chromosome cause an X-linked recessive disorder.


Mitochondrial or multigenic Mitochondrial genetic disorders can be caused by changes (mutations) in either the mitochondrial DNA or nuclear DNA that lead to dysfunction of the mitochondria and inadequate production of energy.

Multigenic or multifactor Inheritance involving many factors, of which at least one is genetic but none is of overwhelming importance, as in the causation of a disease by multiple genetic and environmental factors.

Dentin dysplasia type II (DD-II) is a rare mild form of dentin dysplasia (DD, see this term) characterized by normal tooth roots but abnormal primary dentition.

Prevalence of DD-II is not known.

Clinical description
In DD-II, features of primary dentition resemble those observed in dentinogenesis imperfecta type 2 (DGI-2, see this term) and include amber translucent coloration, bulbous crowns, cervical constriction, tooth attrition, and short constricted roots. Pulp obliteration is also observed. The permanent dentition seems either unaffected (normal teeth morphology and color) or mild radiographic abnormalities are found (thistle tube-shaped pulp chambers and multiple pulp calcifications).

DD-II is caused by mutations in the DSPP gene (4q21.3) coding for dentin sialophosphoprotein, a precursor for dentin sialoprotein and dentin phosphoprotein which are involved in dentinogenesis.

Diagnostic methods
Diagnosis is based on history, clinical examination and radiographic features. Molecular genetic testing can be used to confirm the diagnosis.

Differential diagnosis
Differential diagnoses include conditions that have similar clinical or radiographic features to DD such as osteogenesis imperfecta or dentinogenesis imperfecta (see these terms).

Genetic counseling
DD-2 follows an autosomal dominant pattern of inheritance. There is therefore a 50% chance that a child born to an affected parent will have the condition.

Management and treatment
In the primary dentition, preformed stainless steel crowns on molars may be used to prevent tooth wear and maintain the occlusal vertical dimension. Appropriate care makes it possible to achieve good esthetic appearance and functional performance.

Prognosis depends primarily on the age of diagnosis and the quality of management.

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.
