What Is Type II Dentin Dysplasia
Also known as coronal dysplasia, this condition affects the crowns of teeth (the part of a tooth that's visible above the gumline) as well as the pulp chamber. According to Medline Plus, type 2 dentin dysplasia most commonly affects primary teeth. When children have this condition, their baby teeth' enamel appears translucent with a yellow, brown, grey, or brownish-blue coloring, and the pulp chambers are obscure or non-existent.
When adult teeth are affected by type II dentin dysplasia, they can appear normal. Still, the dentin beneath the outer enamel layer is weak and eventually causes the enamel to wear or chip away. According to NORD, pulp chambers in adult teeth with this condition have a flame-shaped appearance in x-rays, show abnormal extensions toward the roots, and the pulp chambers can contain calcifications called pulp stones.
There are similar disorders called dentinogenesis imperfecta type II and III that, according to MedlinePlus, some researchers believe may be forms of the same disorder as Type II dentin dysplasia. The conditions share many of the same signs and symptoms.
In cases of both type 1 and type 2 dentin dysplasia, practicing good oral hygiene and visiting your dental professional regularly is the best way to prolong the health of your teeth. If your condition results in tooth loss, speak with your dental professional about what replacement tooth options will be best for you. Even with dentin dysplasia, you can work together with your dental professional to maintain a healthy smile.
