Teeth01:15

Teeth

1.3K
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

1.7K
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...

Bone Formation by Intramembranous Ossification01:29

Bone Formation by Intramembranous Ossification

9.2K
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 ...

Changes in the Appendicular Skeleton with Age

3.1K
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...

Bone Formation by Endochondral Ossification01:24

Bone Formation by Endochondral Ossification

7.3K
Bone formation, or ossification, begins around the sixth to seventh week of embryonic development. Most bones develop from a cartilaginous template through the process of endochondral ossification. Cartilage formation begins when clusters of mesenchymal cells differentiate into chondrocytes. These chondrocytes proliferate rapidly and secrete an extracellular matrix that becomes encased in a membrane called the perichondrium. The resulting cartilage model provides a template that resembles the...

Sutures of the Skull01:22

Sutures of the Skull

9.3K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Summary
This summary is machine-generated.

Children with supernumerary teeth (ST) show advanced dental development compared to those without. Panoramic radiography is adequate for assessing dental age (DA) using the Demirjian method, with ST potentially influencing DA estimation.

Area of Science:

  • Pediatric Dentistry
  • Dental Radiology
  • Orthodontics

Background:

  • Supernumerary teeth (ST) are extra teeth that can impact dental development and eruption patterns.
  • Accurate dental age (DA) estimation is crucial for orthodontic treatment planning and growth assessment in children.
  • Radiographic methods, including panoramic radiography and cone-beam computed tomography (CBCT), are used for DA assessment.

Purpose of the Study:

  • To compare radiographic permanent tooth development in children with and without supernumerary teeth (ST).
  • To evaluate the accuracy of dental age (DA) estimation using cone-beam computed tomography versus panoramic radiography.
  • To investigate the influence of ST number and location on DA estimation.

Main Methods:

  • Analysis of 150 dental radiographs from children aged 6.0 to 14.9 years, matched for age and sex.
  • Dental age (DA) determination using the Demirjian method on the lower left permanent teeth.
  • Calculation of the difference between chronological age (CA) and dental age (DA) (CA-DA) in relation to ST presence, number, and location.

Main Results:

  • Mean DA values were higher than mean CA values across all groups.
  • The CA-DA difference was greater in children with ST compared to those without.
  • Posteriorly located, multiple ST, and male gender were associated with increased CA-DA differences.

Conclusions:

  • Panoramic radiography is sufficient for dental development assessment using the Demirjian method.
  • Children with supernumerary teeth exhibit more advanced dental development than their non-ST counterparts.
  • Clinicians should consider advanced dental development in children diagnosed with supernumerary teeth.
