Apexification Procedure:

Endodontics Miscellaneous Apexification Procedure

Question 2. Role of Radiographs in Endodontics.
Answer.

Role of Radiographs in Endodontics

  • Assess root form and length
  • Assess the dimension of root canals
  • Assess the progression of caries
  • Assess the presence of any obstructions, resorptions
  • Assess lamina dura
  • Periapicaltrabeculae pattern
  • Root fracture
  • Evaluate cases

Radiographs in Endodontics Limitations:

  • 2-dimensional representation
  • Necrosis cannot be determined
  • Difficult to differentiate periapical lesions
  • Overlapping of anatomic landmarks

Question 3. Glutaraldehyde.
Answer.

Glutaraldehyde

  • Toxic, irritant, allergenic
  • High-level disinfectant
  • Use – For disinfection of heat-sensitive material
  • Activation – By addition of Sodium bicarbonate
  • Remains potent for 14 days
  • Manner – 2% glutaraldehyde
  • Immersion for 20 min – for disinfections

Question 4. Sodium perborate.
Answer.

Sodium perborate

  • Constituent of bleaching gel
  • Available form – Monohydrate
    • Trihydrate
    • Tetrahydrate
  • Composition – 95% perborate + 10% oxygen

Question 5. Weeping Canals.
Answer.

Weeping Canals

  • After root canal treatment in some cases reddish exudates appears with periapical radiolucency

Weeping Canals Feature: Asymptomatic/Tender on percussion

  • When opened in next appointment, exudates stop by again reappears in next appointment
  • This is called “Weeping Canal”

Weeping Canals Treatment 1:

Endodontics Miscellaneous Weeping Canals Treatment

Reason: The pH of periapical area is acidic which turns to basic by Calcium hydroxide.

Question 6. Bicuspidization/Hemisection.
Answer.

Bicuspidization/Hemisection

Section of the root along with the respective crown portion

Bicuspidization Indications:

  • Periodontal disease
  • Severe bone loss
  • Untreatable roots
  • Root fracture

Bicuspidization Contra Indications:

  • Fused roots
  • Lack of Osseous support
  • Uncooperative patients

Question 7. Incision and Drainage.
Answer.

Incision and Drainage Indication:

  • Purulent/Hemorrhage exudates

Incision and Drainage Protocol:

  • Intraoral and localized swelling
    • Only incision and drainage
  • Intraoral, diffuse swelling
  • Incision and drainage
  • Followed by systemic antibiotics

Incision and Drainage Hard And Diffuse:

  • Allow to become soft and localized
  • Incision and drainage done thereafter
  • Horizontal incision is given on the dependent part by blade No.11 or 12

Question 8. Endodontic Implants.
Answer.

Endodontic Implants Indications:

  • Periodontally weak teeth
  • Root fracture
  • Short root
  • Root resorption

Endodontic Implants Contraindications:

  • Curved canal
  • Proximity to anatomic structures
  • Insufficient tooth support.

Question 10. Management of separated instruments.
Answer.

Management of separated instrument

  • Diagnose radiographically

Management of separated instrument Retrieval System:

  • Masserian kit
  • Endo extractor
    • It consists a wedge that holds the instrument and removes it
  • Instrument retrieval system [IRS]
