Abstract:
Dentinogenesis imperfecta, also known as hereditary opalescent dentin, is a dentin development disorder with autosomal dominant transmission that affects both the primary and permanent dentition. A case is reported of a family in which the mother and her 6- and 20-year-old children were diagnosed with dentinogenesis imperfecta type II. The mouths of these patients illustrate the progressive deterioration of affected teeth if not adequately treated. The treatment of the 6-year-old son is described, and therapeutic approaches to this disorder in primary and permanent dentition are reviewed. This family exemplifies the need for the earliest possible diagnosis and treatment of dentinogenesis imperfecta to prevent extensive deterioration of the dentition and occlusion.

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
