Summary
Dental calcification stages correlate positively with skeletal maturation in Peruvian youth. The second mandibular molar
Area of Science:
- Orthodontics
- Pediatric Dentistry
- Radiology
Background:
- Skeletal maturation is crucial for orthodontic treatment timing.
- Dental calcification stages offer a potential indicator for skeletal age.
Purpose of the Study:
- To investigate the relationship between dental calcification stages and skeletal maturation in a Peruvian population.
- To assess correlations using hand-wrist and cervical vertebrae methods.
Main Methods:
- Radiographic analysis of 78 Peruvian patients (7-17 years old).
- Evaluation of dental calcification (mandibular canine, premolars, second molar) and skeletal maturation (hand-wrist, cervical vertebrae).
- Spearman's correlation and Fisher's exact test were employed.
Main Results:
- All teeth exhibited positive, significant correlations with skeletal maturation.
- The second mandibular molar's calcification showed the strongest correlation with both hand-wrist (r=0.758) and cervical vertebrae (r=0.605) maturation.
- Pubertal growth spurt and mandibular growth peak were linked to specific calcification stages of the second molar.
Conclusions:
- A positive relationship exists between dental calcification and skeletal maturation in the studied Peruvian sample.
- Dental calcification, particularly of the second mandibular molar, serves as a reliable indicator for assessing skeletal maturation.

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...

01:21Skeleton and Calcium Homeostasis
6.3K
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

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...

01:29Bone Disorders
5.7K
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...

01:17Hormones and Bone Tissue
4.0K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
