Teeth01:15

Teeth

2.3K
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...

Tooth Anatomy

3.0K
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...

Anatomical Movements00:51

Anatomical Movements

18.8K
Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...

Cranial Nerves: Types Part II

6.0K
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.
Facial Nerve (Cranial Nerve VII)
Cranial nerve VII, or the facial nerve,...

The Hyoid Bone01:12

The Hyoid Bone

6.8K
The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...

Bone Formation by Intramembranous Ossification01:29

Bone Formation by Intramembranous Ossification

17.4K
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.

Root resorption in baby teeth speeds up with orthodontic treatment due to increased mediators. This early exfoliation risk must be weighed against potential clinical benefits.

Area of Science:

  • Dentistry
  • Developmental Biology
  • Cell Biology

Background:

  • Deciduous teeth exfoliation is a natural process involving cementoblast-induced apoptosis.
  • Root resorption is typically slow but accelerates with proximity to permanent tooth follicles and bone resorption mediators like EGF.

Purpose of the Study:

  • To investigate the impact of orthodontic movement and anchorage on deciduous teeth root resorption.
  • To highlight the accelerated exfoliation risk associated with orthodontic interventions on primary teeth.

Main Methods:

  • The study discusses the biological mechanisms of root resorption in deciduous teeth.
  • It reviews the role of epithelial growth factor (EGF) and other mediators in bone and root resorption.
  • The abstract implies a review or discussion of clinical scenarios involving orthodontic treatment.

Main Results:

  • Orthodontic movement or anchorage of deciduous teeth increases local mediator levels.
  • This increase significantly accelerates root resorption and leads to premature exfoliation.
  • Permanent tooth eruption mediators are key drivers of deciduous tooth root resorption.

Conclusions:

  • Orthodontic interventions on deciduous teeth carry a significant risk of accelerated root resorption and early exfoliation.
  • Treatment planning must carefully evaluate the clinical benefits against the risk of premature tooth loss.
  • Understanding the role of mediators like EGF is crucial for managing deciduous teeth during orthodontic treatment.
