Dental Clasps in Orthodontics
Circumferential Clasp (C-Clasp)
This clasp utilizes the bucco-cervical undercut and is commonly used on second molars and canines. It features a single retention arm made of 1mm wire.
Advantages:
- Good retention
- Easy fabrication and replacement
- Single occlusal crossover wire
Disadvantages:
- Not suitable for semi-erupted teeth
- Potential for decalcification, gingival irritation, and plaque accumulation
- Susceptible to distortion
Jackson Clasp (Full Clasp, U Clasp)

Understanding Toxicology
Definition and Scope
Toxicology is the multidisciplinary science that studies the adverse effects of xenobiotics (Xb) on living systems. It encompasses the identification of Xb, their mechanisms of action, and strategies to prevent and mitigate toxic phenomena.
Key Concepts
- Toxic phenomena: The toxicity of a compound is determined by the steps of the biological process, starting with toxicokinetics (LADME).
- Dangerous substance: Toxicity is determined by both the toxic phenomena
