Chromic gut Suture vs Plain gut Suture

# Advantage of chromic gut over plain is:
A. Delayed resorption
B. Increased strength
C. Less irritation
D. Less tissue reaction

The correct answer is A. Delayed resorption.

  • Chromic gut sutures consist of the plain gut that has been treated with chromium trioxide. This results in a delay in the absorption rate.
  • Because retention of sutures beyond a few days is not recommended in endodontic surgery, the use of chromic gut sutures offers no advantage.
  • Also, evidence indicates that plain gut is more biocompatible with oral soft tissues than is the chromic gut. The gut suture material is marketed in sterile packets containing isopropyl alcohol.
  • When removed from the packet, the suture is hard and non-pliable because of its dehydration. Before using gut sutures should be hydrated by placing them into sterile, distilled water for 3 to 5 minutes.
  • After hydration, the gut suture material will be smooth and pliable with manipulative properties similar to silk.


  1. I have a doubt though, it can abe like this also,Chromic acid used in chromic gut increases tensile the tensile strength is more it leads to delayed resorption of the chromic gut.

    1. The same thing is mentioned above. What is the exact point of confusion?
