Endodontics - 3 Questions

1
Endodontics
A patient under fixed orthodontic therapy got his anterior tooth injured and became non-vital. You would like to 
 1. Perform endodontic therapy without disturbing bands and arch wires
 2. Remove arch wire and perform endodontic therapy
 3. Both of the above
 4. None of the above

📝 Explanation:

Endodontic treatment can be performed without removing orthodontic appliances. Access can be gained through the lingual surface or by carefully working around brackets. Removing arch wires interrupts orthodontic treatment unnecessarily.

Activity of disinfectants is
1) Reduced by organic debris or blood
2) Increased with heat
3) Hastened by adding 5 % oxygen
4) Nullified by ethylene dioxide gas

📝 Explanation:

Activity of disinfectants is indeed reduced by organic debris or blood. This is because organic materials can act as a barrier, protecting microorganisms from the disinfectant and reducing its effectiveness. The presence of organic matter can bind to the disinfectant, inactivate it, or consume it, thereby reducing its ability to kill or inhibit the growth of microorganisms. For this reason, it is essential to thoroughly clean and debride the area before applying a disinfectant to ensure optimal efficacy.

Cold response of irreversible pulpitis is
1) When cold is applied to a tooth and removed the pain persists
2) There is pain on application of cold and disappears on removal
3) No reaction to cold
4) All of the above

📝 Explanation:

Irreversible pulpitis is characterized by sharp, severe pain that continues even after the stimulus (such as cold) has been removed.

The pain is typically spontaneous or continuous and can be intense.

In contrast, reversible pulpitis causes pain only when the stimulus is applied, which disappears shortly after removal.

The persistent pain is a key diagnostic sign indicating that the pulp is inflamed beyond recovery and requires endodontic treatment or extraction.
