Establishing Organoids from Human Tooth as a Powerful Tool Toward Mechanistic Research and Regenerative Therapy
Published on: April 13, 2022
[Enamel structure of atypically formed human teeth].
Summary
This study examined enamel damage in impacted teeth and a tooth-like teratoma. Both showed endogenous enamel erosion, with the teratoma exhibiting lesions resembling fluorosis or enamel hypoplasia.
Area of Science:
- Dental histology
- Pathology
- Biomineralization
Context:
- Investigated enamel alterations in impacted third molars and a unique tooth-like teratoma.
- Utilized light and scanning electron microscopy for detailed structural analysis.
- Examined specimens including 12 impacted third molars, one odontogenic cyst-derived molar, and one ovarian teratoma.
Purpose:
- To characterize and compare enamel damage in impacted teeth and a tooth-like teratoma.
- To determine the origin and nature of observed enamel alterations.
- To differentiate pathological changes from developmental anomalies.
Summary:
- Four impacted teeth and one tooth from an odontogenic cyst displayed enamel erosion in crown fissures, indicative of endogenous carious processes.
- A tooth-like teratoma showed significant enamel erosive lesions of endogenous origin, distinct from impacted teeth.
- Teratoma enamel alterations were morphologically similar to fluorosis or enamel hypoplasia, differing from carious changes.
Impact:
- Provides insights into the endogenous origins of enamel damage in dental anomalies.
- Contributes to understanding the differential diagnosis of enamel defects in developmental abnormalities.
- Highlights the utility of microscopy in identifying subtle enamel pathologies.

Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
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.

Teeth
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
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...

Bone Structure
Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.
Gross Anatomy of Bone
The two main features of a long bone are the diaphysis and the epiphysis.
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in adults, it...

Compact Bone
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

Bone as Supporting Connective Tissue
Bone tissue forms the internal skeleton of vertebrate animals, providing structure to the body.
Bone Matrix
Bone, or osseous tissue, is a connective tissue that has a large amount of two different types of matrix material. The organic matrix is similar to the matrix material found in other connective tissues, including some amount of collagen and elastic fibers. This gives strength and flexibility to the tissue. The inorganic matrix consists of mineral salts— mostly calcium salts— that give the...
