Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

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.

Summary
This summary is machine-generated.

Removing all infected dentin from vital teeth is unnecessary and potentially harmful. Evidence suggests leaving some infected dentin is safe if the cavity seal is adequate, preventing further caries progression and preserving pulpal health.

Area of Science:

  • Dentistry
  • Dental Caries Management

Background:

  • Current dental practices often involve complete removal of infected dentin during caries treatment.
  • This approach may be biologically questionable for asymptomatic, vital teeth.

Purpose of the Study:

  • To evaluate the necessity and biological impact of complete infected dentin removal in caries management.
  • To assess the outcomes of leaving infected dentin when restorations provide an adequate seal.

Main Methods:

  • Review of existing evidence on caries removal techniques.
  • Analysis of the biological consequences of different caries removal strategies.

Main Results:

  • Complete removal of infected dentin is neither feasible nor required for symptomless, vital teeth.
  • Leaving infected dentin does not compromise pulpal health.
  • Adequately sealed restorations prevent further caries progression even with residual infected dentin.

Conclusions:

  • The practice of complete caries removal warrants re-evaluation.
  • Conservative caries removal, leaving sealed infected dentin, is a viable approach that preserves tooth vitality and prevents lesion progression.
