What are symptoms of dentinogenesis imperfecta?
Dentinogenesis imperfecta is a condition characterized by teeth that are translucent and discolored (most often blue-grey or yellow-brown in color). Individuals with this disorder tend to have teeth that are weaker than normal, which leads to wear, breakage, and loss of teeth.
Which stage dentinogenesis imperfecta occur?
Dentinogenesis imperfecta (DI) is an autosomal dominant trait, its frequency of occurrence is about 1 in 8000. This inherited dentin defect originates during the histodifferentiation stage of tooth development. The predentin matrix is defective resulting in amorphic, disorganized, and atubular circumpulpal dentin.
Is dentinogenesis imperfecta rare?
You might be showing signs of dentinogenesis imperfecta. Dentinogenesis imperfecta (DI) is a rare genetic disorder that affects the dentin of your teeth. Recognizing the signs and symptoms and consulting your dental professional will help you understand this uncommon dental condition.
What is the cause of dentinogenesis imperfecta?
Dentinogenesis imperfecta type I occurs as part of osteogenesis imperfecta, which is caused by mutations in one of several other genes (most often the COL1A1 or COL1A2 genes). The DSPP gene provides instructions for making two proteins that are essential for normal tooth development.
What is the difference between dentin dysplasia and Dentinogenesis imperfecta?
A. Dentinogenesis imperfecta: The teeth are translucent and often roughened with severe amber discolouration. B. Dentine dysplasia: The primary teeth are translucent and amber in colour whereas the erupting secondary central incisors are of normal appearance.
What is Taurodontism of teeth?
Taurodontism is a dental anomaly defined by enlargement of the pulp chamber of multirooted teeth with apical displacement of the pulp floor and bifurcation of the roots. Taurodontism can be an isolated trait or part of a syndrome.
Where does dentinogenesis begin?
Dentinogenesis is initiated by the inductive influence of the enamel organ involving molecular signaling pathways, such as Wnt, Runx-2, and TGF-β. In the molar tooth, dentinogenesis starts at the late bell stage, and occurs in the crown as well as root regions.
Is Dentinogenesis imperfecta dominant?
Occurs in people without other inherited disorders (i.e. Osteogenesis imperfecta). It is an autosomal dominant trait.
Is Dentinogenesis Imperfecta recessive or dominant?
Dentinogenesis imperfecta type III is inherited as an autosomal dominant trait. The abnormal (mutated) gene has been tracked to a site on the long arm of chromosome 4 at band 21.3 (4q21. 3). Interestingly, this gene is thought to code for two major dentin proteins — dentin sialoprotein and dentin phosphoprotein.
What determines where the CEJ is placed on the tooth?
In only 5–10% of teeth, there is a space between the enamel and the cementum at which the underlying dentin is exposed….
| Cementoenamel junction | |
|---|---|
| The CEJ is the more or less horizontal demarcation line that distinguishes the crown (A) of the tooth from root (B) of the tooth. | |

How do you treat Hutchinson’s teeth?
To treat Hutchinson teeth, first visit your pediatrician for a diagnosis and medication, if needed. A blood test or sometimes lumbar puncture can confirm syphilis. Treatment options include a shot of penicillin. If the disease has been present longer than a year, your child may need additional doses.
What does dentinogenesis imperfecta type 3 look like?
Dentinogenesis imperfecta type 3 is a rare and severe form of dentinogenesis imperfecta, a condition that affects tooth development. People affected by this condition generally have discolored (most often a blue-gray or yellow-brown color) and translucent teeth.
Can a dental X-ray tell if you have dentinogenesis imperfecta?
A dental X-ray is specifically helpful in diagnosing dentinogenesis imperfecta. The specific signs found in a clinical exam may differ depending on the type of dentinogenesis imperfecta: Type I: people who have type I dentinogenesis imperfecta also have osteogenesis imperfecta.
How is dentinogenesis imperfecta inherited from the mother?
Inheritance Inheritance. Dentinogenesis imperfecta is inherited in an autosomal dominant manner, which means only one changed copy of DSPP in each cell is sufficient to cause the disorder. We inherit one copy of each gene from our mother and another copy from our father.
What are the treatment options for dentinogenesis imperfecta?
Treatment varies according to the age of the patient, severity of the problem, and presenting complaint. Treatment options include amalgams as dental fillings, veneers to fix the discoloration of teeth, crowns, caps, and bridges. [6]
