Dentinogenesis Imperfecta is a condition that causes issues with the development of teeth. Teeth affected by this condition tend to have a blue-ish, grey or yellow discolouration and are slightly translucent. Dentinogenesis imperfect can make teeth more fragile and therefore more prone to chipping, fracturing and breaking. It can affect both primary (baby teeth) and permanent teeth (adult teeth).
There are three types of dentinogenesis imperfecta, the first type related to a condition called osteogenesis imperfecta, which is a genetic condition that causes bones to be more brittle. Dentinogenesis imperfecta affects 1 in 8000 people. It is essential for a prognosis that the condition is caught in the early stages.
Causes of Dentinogenesis Imperfecta
The cause of dentinogenesis imperfecta is a mutation of a gene that is responsible for providing instructions for normal tooth formation, including creating the dentin, which is the middle layer of the tooth. The disrupted gene creates softer than normal dentin. The condition has a genetic link and may be inherited.
Dentinogenesis Imperfecta Tooth Appearance
This condition can affect both adult and baby teeth. It appears as a blue/grey or yellow internal staining and can be associated with pitted looking enamel. Teeth may also have a see-through appearance at the edges.
Treatment of Teeth Affected by Dentinogenesis Imperfecta
The treatment for dentinogenesis imperfecta is mainly maintenance of symptoms. This is done by eliminating infection and pain, restoring proper function and improving aesthetics. Stainless steel crowns may be used for primary teeth (baby teeth) to maintain function and hold the places for the adult teeth to erupt. For adult teeth, chips and fractures will need to be fixed with dental fillings, and in more severe cases, dental crowns will be needed for adequate function and aesthetic. The treatment for dentinogenesis imperfecta largely depends on the severity of the condition and how early the treatment is performed.
Dentinogenesis Imperfecta Prognosis
The prognosis is based on how swiftly the condition is diagnosed, and when the teeth are treated. If caught early and required treatment performed, the prognosis for dentinogenesis imperfecta is good.
