Summary
Dental development accelerates in precocious puberty and slows in delayed puberty, differing significantly from chronological and skeletal ages. This study compared dental and skeletal development in children with various pubertal timings.
Area of Science:
- Pediatric Endocrinology
- Orthodontics
- Radiology
Background:
- Precocious puberty involves early growth onset, while delayed puberty signifies growth retardation.
- Assessing dental and skeletal development is crucial for understanding somatic development patterns.
- Synchronicity between dental, skeletal, and chronological ages is a key indicator of normal development.
Purpose of the Study:
- To investigate the synchronicity between dental and somatic development in children with precocious and delayed puberty.
- To compare dental and skeletal ages with chronological ages in different pubertal development groups.
- To determine if dental development patterns align with somatic development in pubertal variations.
Main Methods:
- Evaluated 169 children with normal development, precocious puberty, and delayed puberty.
- Determined dental age using the Demirjian method on panoramic radiographs.
- Assessed skeletal age via the Greulich-Pyle atlas on hand-wrist radiographs.
Main Results:
- Dental age values were significantly higher than chronological and skeletal ages across all groups.
- In precocious puberty, dental age significantly exceeded chronological age.
- No statistically significant difference was found between chronological and dental age in the delayed puberty group.
Conclusions:
- Dental development appears accelerated in precocious puberty compared to chronological and skeletal development.
- Dental development seems retarded in delayed puberty, though not statistically significant compared to chronological age.
- Findings suggest dental age assessment can indicate pubertal development status, with potential biases in specific methods.

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...

Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

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...

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.

Following the phallic stage in Freud's theory of psychosexual development, children enter a phase called the latency period, which lasts from approximately six to twelve years of age. Unlike earlier stages, where sexual impulses played a central role, Freud believed these impulses are repressed during the latency period, becoming part of the unconscious. This stage is often described as a time of psychological calm after the turbulence of the phallic stage.

01:14Psychosexual Theory of Development
1.2K
Sigmund Freud's psychosexual theory of development suggests that early childhood experiences significantly shape personality and behavior. Freud proposed that development is discontinuous, occurring in five distinct stages, each defined by a focus on different erogenous zones. He believed that failure to resolve the conflicts specific to each stage successfully could result in fixation, potentially influencing behavior as adults.
