Summary
Transient apical breakdown (TAB) is a reversible tooth resorption during orthodontic treatment. Removing orthodontic forces allows the tooth to heal, indicated by improved color and sensitivity.
Area of Science:
- Dentistry
- Endodontics
- Orthodontics
Background:
- Transient apical breakdown (TAB) is a reversible resorptive process affecting tooth apices during orthodontic treatment.
- Radiographic evidence includes apical resorption and potential crown discoloration.
- Typically managed by monitoring and removing orthodontic forces.
Observation:
- A 48-year-old male presented with discoloration of an upper right central incisor undergoing orthodontic treatment.
- The affected tooth showed non-responsiveness to sensitivity tests, percussion sensitivity, and radiographic signs of apical resorption and radiolucency.
Findings:
- Transient apical breakdown (TAB) was suspected as the cause of the patient's symptoms.
- No active endodontic treatment was performed; management involved periodic monitoring and reducing orthodontic forces.
- After 10 weeks of force removal, the tooth exhibited improved coloration and restored sensitivity to cold stimuli.
Implications:
- This case highlights the reversible nature of transient apical breakdown (TAB).
- Non-invasive management by eliminating orthodontic forces can lead to favorable outcomes.
- Emphasizes the importance of monitoring and timely intervention in orthodontic-related dental complications.

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 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 remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
