The Bone Matrix01:18

The Bone Matrix

Bone contains a relatively small number of cells entrenched in a matrix of collagen fibers that provide an adherent surface for inorganic salt crystals. Both components of the matrix, organic and inorganic, contribute to the unusual properties of bone. Without collagen, bones would be brittle and shatter easily. Without mineral crystals, bones would flex and provide little support. This can be observed by an experiment: when the minerals of a bone are dissolved by soaking the bone in acid or...
Essential Minerals for Bone Health01:31

Essential Minerals for Bone Health

The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
Crystal Density01:19

Crystal Density

The crystal lattice structure of a material allows us to determine how many molecules exist in its unit cell. With this information, alongside the unit-cell parameters - three distance parameters (a, b, c) and three angular parameters (α, β, γ).Density (ρ) = (Z × M) / (a × b × c × NA)where:Z is the number of formula units per unit cellM is the molar mass of the substancea, b, and c are the edge lengths of the unit cellNA is Avogadro’s numberFor a simple cubic lattice, atoms are located only at...
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 Disorders01:29

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Bone Formation by Intramembranous Ossification01:29

Bone Formation by Intramembranous Ossification

Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...

Area of Science:

  • Oral and Maxillofacial Radiology
  • Biomedical Imaging
  • Dental Anatomy

Background:

  • Mandibular condyle bone density is crucial for diagnosing and treating various dental conditions.
  • Accurate assessment of bone density distribution is essential for understanding condyle biomechanics.
  • Existing imaging methods may have limitations in precisely quantifying bone density variations within the mandibular condyle.

Purpose of the Study:

  • To evaluate a novel computerized tomography (CT) software method for assessing mandibular condyle bone density and distribution.
  • To determine the accuracy and utility of this CT-based technique in differentiating bone density within the condyle.

Main Methods:

  • High-resolution multislice CT was used to examine 38 mandibular condylar specimens.
  • Proprietary software with bone density analysis algorithms estimated apparent density across different regions (total area, trabecular bone, selected points).
  • Color-coded images were generated to visualize bone density variations.

Main Results:

  • Cortical bone exhibited significantly higher densities compared to trabecular bone.
  • Anterior cortical bone was denser than posterior cortical bone.
  • Central anterior cortical and trabecular areas showed higher densities than medial and lateral regions.

Conclusions:

  • The evaluated CT technique is a valuable tool for quantifying mandibular condyle bone density differences.
  • This imaging modality demonstrates potential for specific clinical applications in dentistry.
  • The findings support the use of this advanced CT software for detailed condyle analysis.
