Summary
Dental calcification stages accurately assess skeletal maturity in growing individuals, offering a reliable alternative to hand-wrist radiographs for orthodontic treatment planning. This method is particularly useful during the prepubertal growth period.
Area of Science:
- Orthodontics
- Pediatric Dentistry
- Radiology
Background:
- Accurate skeletal maturity assessment is crucial for orthodontic treatment planning in growing patients with skeletal discrepancies.
- Hand-wrist radiography is the gold standard but involves radiation exposure.
- Dental calcification stages offer a potential alternative to reduce radiation exposure.
Purpose of the Study:
- To evaluate the efficacy of dental calcification stages in assessing skeletal maturity during prepubertal and pubertal growth periods.
Main Methods:
- Dental maturity was assessed using the Demirjian method on panoramic radiographs.
- Skeletal maturity was determined using the Björk method.
- Four permanent left mandibular teeth (canine, 1st premolar, 2nd premolar, 2nd molar) were analyzed.
Main Results:
- Strong, statistically significant correlations (0.789–0.835) were found between skeletal and dental maturation.
- The second molar showed the highest correlation (r=0.829 in males, 0.88 in females).
- The sum of dental stages demonstrated high validity for identifying MP3= stage (sensitivity 70%, specificity 92.77%).
Conclusions:
- Dental calcification stages exhibit a high correlation with skeletal maturity stages.
- Orthodontists can utilize dental stages as a reliable diagnostic tool, especially for the prepubertal growth period.

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...

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...

01:22Sutures of the Skull
8.8K
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...

01:20Introduction to the Skeletal System
7.9K
The skeletal system is the central framework of the body, consisting of different connective tissues: bones, cartilage, tendons, and ligaments.
Components of the Skeletal System
Bone, or osseous tissue, is a hard connective tissue that forms an internal support structure for the human body. Bones shield vulnerable organs and soft tissue from external forces. For example, the vertebral bones protect and support the spinal cord.
Cartilage, a semi-rigid connective tissue found in regions such as...

1.9K
The oral stage is the initial phase of Sigmund Freud's theory of psychosexual development, occurring from birth to approximately 12 to 18 months. During this period, the infant's mouth serves as the primary source of pleasure, with actions such as sucking, chewing, biting, and drinking playing a crucial role in reducing tension. These activities are essential not only for nourishment but also for the infant's psychological and emotional satisfaction.

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...
