Endodontics - 3 Questions

1
Endodontics
Stabilisation of avulses tooth requires 
 1. 1-2 weeks
 2. 2-3 weeks
 3. 4-6 weeks
 4. More than 6 weeks

📝 Explanation:

Stabilization of avulsed tooth requires 1-2 weeks of splinting. This short period is recommended because: 1) Brief splinting allows periodontal ligament healing without ankylosis, 2) Extended splinting (>2 weeks) increases risk of replacement resorption and ankylosis, 3) Early mobilization promotes functional healing of periodontal ligament fibers, 4) Studies show optimal healing occurs with flexible splinting for 7-14 days, 5) Longer periods compromise the natural healing process and increase complications. Rigid or prolonged splinting should be avoided.

The treatment of acute periapical abscess is
1) Endodontic therapy or extraction
2) Incision and drainage only
3) Pulp capping
4) None of the above

📝 Explanation:

The first line of treatment for an acute apical abscess with swelling is to establish drainage. This relieves pressure, reduces pain, and removes the source of infection.

Home bleach is also called as 
 1. Walking bleach
 2. Thermocatalytic bleach
 3. Power bleach
 4. All of the above

📝 Explanation:

Home bleach is also called walking bleach, specifically referring to the technique used for non-vital teeth where bleaching agent is sealed inside the tooth and the patient "walks around" with it between appointments. The walking bleach technique involves: 1) Placing sodium perborate or hydrogen peroxide inside the pulp chamber, 2) Sealing the access cavity with temporary restoration, 3) Patient returns after 3-7 days for evaluation, 4) Process repeated until desired shade is achieved. This differs from thermocatalytic and power bleach which are in-office techniques.
