Question 1. Zipping.

Zipping Definition:

  • Zipping is defined as the apical transportation of a curved canal caused due to improper shaping technique

Zipping Features:

  • Zip formation adopts an elliptical shape at the apical endpoint.
  • Zipping is caused by using progressively larger and stiffer files to working length.
  • It can result in a poorly cleaned root canal, which fails to provide a resistance form to compact gutta-percha, and leads to obturation which is vertically over-extended but internally under-filled.
  • This contributes to leakage, infection, and failure.
