Bone Disorders01:29

Bone Disorders

3.5K
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 Remodeling01:40

Bone Remodeling

38.3K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Changes in the Appendicular Skeleton with Age

2.0K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

2.9K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

Bone Formation by Intramembranous Ossification01:29

Bone Formation by Intramembranous Ossification

6.1K
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 ...

Summary
This summary is machine-generated.

Menopause significantly impacts mandibular condylar bone, increasing trabecular separation and reducing bone density. However, basal bone in the mandible remains largely unaffected by menopausal status.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Bone Biology
  • Menopause Research

Background:

  • Conflicting reports exist regarding estrogen's effect on mandibular bone microarchitecture.
  • The impact of menopause on different mandibular regions remains unclear, affecting treatment planning.

Purpose of the Study:

  • To evaluate and compare trabecular and cortical bone microstructure in the mandibular condyle and basal bone.
  • To assess differences between premenopausal and postmenopausal women.

Main Methods:

  • Cross-sectional cohort study at Columbia University Irving Medical Center.
  • Cone-beam computed tomography (CBCT) used for mandibular condyle and basal bone analysis.
  • Quantitative microstructure analysis of bone parameters including bone volume fraction, thickness, number, and separation.

Main Results:

  • Postmenopausal women exhibited significantly greater condylar trabecular separation and lower trabecular number compared to premenopausal women.
  • No significant differences in basal bone microarchitectural parameters were observed between menopausal groups.
  • Significant differences in age and estrogen levels were noted between premenopausal and postmenopausal groups.

Conclusions:

  • Menopause is linked to mandibular condylar trabecular bone loss.
  • Mandibular basal bone shows minimal changes related to menopausal status.
  • Findings have implications for treatment planning in aging populations, particularly concerning mandibular bone health.
