Answer.

“Steps to explain causes of dentin dysplasia: Genetic vs developmental factors: Q&A guide”

It is an autosomal dominant inherited disorder characterized by defective dentin formation and abnormal pulp morphology.

• The condition is also known as “rootless teeth”.
• It is classified into two types
  • Type I: Radicular dentin dysplasia
  • Type II: Coronal dentin dysplasia

Type 1: Radicular Dentin Dysplasia

It represents a peculiar disturbance in the development of radicular dentin.

Clinical Features

• It affcts both deciduous and permanent dentition.
• Root of teeth is defective and the crown portion of teeth is normal both structurally and morphologically.
• In some cases the crown of teeth reveals slight bluish or brownish tendency.
• Because of presence of functionally unstable short roots,the affcted teeth exhibit mobility.

Histopathology

• Enamel and mantle dentin are normal.
• Remaining coronal and radicular dentin appear fused nodular mass comprising of tubular dentin and osteo dentin.
• Histological appearance of such defective mass of dentinal tissue often reveals what is called as “series of sand dunes” or “lava flwing around boulders”.
• Normal and abnormal dentin is well demarcated and later reveals an abnormal distribution and orientation of dentinal tubules with whorled appearance.

Treatment

No specifi treatment.

Type ii: Coronal Dentin Dysplasia

It is an inherited disorder of dentin, which affcts the coronal dentin.

Clinical Features

• Both deciduous and permanent teeth are affcted.
• Permanent teeth are of normal color whereas deciduous teeth are amber gray color.

Histopathology

• Pulp chambers in permanent teeth are abnormally large
  and have a flme shaped.
• Pulp chamber contains many denticles.
• Root canal may be partially obliterated in apical third region.
