[Initial axonal degeneration in the pulp of deciduous teeth]
Summary
Early nerve fiber degeneration begins in the dental pulp of primary molars in young children (ages 4-5). This axonal degeneration affects the axolemma and internal organelles, particularly at contact sites with fibroblasts.
Area of Science:
- Neuroscience
- Pediatric Dentistry
- Cell Biology
Context:
- The study investigates early degenerative changes in nerve fibers within the dental pulp of deciduous molars.
- Focuses on children aged four to five years, a critical developmental period.
Purpose:
- To identify and characterize the initial stages of regressive processes affecting nerve fibers in primary teeth.
- To detail the specific axonal degenerative changes occurring at the cellular and subcellular levels.
Summary:
- Initial nerve fiber degeneration is observable in the dental pulp of deciduous molars in 4-5-year-old children.
- Degenerative changes are most pronounced at the interface between axons and fibroblasts.
- These changes involve both the axolemma and various organelles within the axoplasm.
Impact:
- Provides foundational knowledge on the timeline of neurodegeneration in primary dentition.
- Highlights the cellular mechanisms underlying early axonal damage in pediatric dental pulp.
- Contributes to understanding the biological basis of sensory changes in young children's teeth.

Overview
Neurogenesis and Regeneration of Nervous Tissue
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...
Teeth
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 and...

Tooth Anatomy
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 grinding food.

Spinal Cord Injury ll: Pathophysiology
Spinal cord injury progresses through two interconnected phases: primary injury and secondary injury.Primary InjuryPrimary injury happens at the moment of trauma and involves immediate mechanical damage to the spinal cord.Compression happens when broken vertebrae, herniated discs, or accumulating blood (such as a hematoma) press directly against the spinal cord, distorting its normal shape and function. In cases of contusion, the cord is bruised by a blunt force (like penetrating injuries or...
Secondary Spinal Cord Injury llI: Pathophysiology
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
