Gross Anatomy of Bone01:17

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...
Spongy Bone01:09

Spongy Bone

All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...
Alveoli and Alveolar Ducts01:26

Alveoli and Alveolar Ducts

The respiratory zone of the human body, which stands in contrast to the conducting zone, comprises the structures that actively participate in the exchange of gases. The initiation of this zone is marked by the terminal bronchioles converging into respiratory bronchioles, the tiniest bronchiole classification. The respiratory bronchioles give way to the alveolar ducts that opens into a congregation of alveoli. Actively involved in gas exchange, alveoli resemble tiny sacs similar to clusters of...
Compact Bone01:27

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 Tissue01:23

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...
Bone Structure01:55

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.

Summary

Various imaging techniques assess alveolar bone changes from oral and systemic diseases. Careful evaluation is needed due to technique limitations, with advanced methods like MRI potentially useful in the future.

Area of Science:

  • Dental imaging and bone densitometry
  • Oral and systemic disease impact on skeletal structures

Background:

  • Alveolar bone quantity and quality are crucial for oral health.
  • Periodontal disease and systemic conditions like osteoporosis affect alveolar bone.

Purpose of the Study:

  • To review current and potential imaging techniques for evaluating alveolar bone.
  • To highlight the importance of considering technique limitations in bone analysis.

Main Methods:

  • Review of established imaging modalities: intra-oral radiographs, panoramic radiographs, computed tomography (CT), and dual-energy X-ray absorptiometry (DXA).
  • Discussion of emerging technologies like magnetic resonance imaging (MRI) for future applications.

Main Results:
