Study Details

Study Description

Brief Summary

The aim of the present study is to assess clinically and radio-graphically the regenerative potential of immature permanent teeth with necrotic pulp using blood clot and Platelet rich fibrin scaffolds.

Condition or Disease Intervention/Treatment Phase
  • Biological: Blood clot scaffold
  • Biological: Blood clot scaffold combined with PRF
Phase 2

Detailed Description

30 immature necrotic permanent teeth in patients will be allocated and divided into two groups. Group 1 will be treated by regenerative procedure using blood clot as a scaffold and Group 2 will be treated with regenerative procedures using combined blood clot and Platelet rich fibrin as a scaffold.

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: Induced blood clot scaffold

Biological: Blood clot scaffold
Bleeding will be induced in the canal by passing a size 30 sterile K-file 3 mm beyond the apex with the goal of having the entire canal filled with blood to the level of the cemento-enamel junction. Bleeding will be stopped just below the cemento enamel junction. Biodentine will be placed approximately 3-4 mm below the cementoenamel junction.

Experimental: Induced blood clot scaffold combined with Platelet rich fibrin

Biological: Blood clot scaffold combined with PRF
Platelet-rich fibrin will be prepared by drawing the patient blood into a 10mL test tube without the addition of an anticoagulant. To prevent the blood from coagulating after coming in contact with the glass tube, it will be centrifuged immediately using a table top centrifuge** at 400 g force for 12 minutes. Then platelet-rich fibrin membrane will be placed into the canal space to a level 3 mm below the cemento-enamel junction using hand plugger following the induction of apical bleeding by passing a number 30 sterile hand file 3 mm beyond the apex of the tooth. Biodentine cap will be placed over the platelet-rich fibrin scaffold.

Outcome Measures

Primary Outcome Measures

  1. Subjective pain assessment [1 month]

    The patient will be asked about the presence of any pain or discomfort. Pain severity will be categorized as: no pain - mild pain - moderate pain - severe pain

  2. Subjective pain assessment [3 months]

    The patient will be asked about the presence of any pain or discomfort. Pain severity will be categorized as: no pain - mild pain - moderate pain - severe pain

  3. Subjective pain assessment [6 months]

    The patient will be asked about the presence of any pain or discomfort. Pain severity will be categorized as: no pain - mild pain - moderate pain - severe pain

  4. Subjective pain assessment [12 months]

    The patient will be asked about the presence of any pain or discomfort. Pain severity will be categorized as: no pain - mild pain - moderate pain - severe pain

  5. Assessment of pulp vitality [1 month]

    Pulp vitality will be assessed using thermal and electric pulp sensibility tests

  6. Assessment of pulp vitality [3 months]

    Pulp vitality will be assessed using thermal and electric pulp sensibility tests

  7. Assessment of pulp vitality [6 months]

    Pulp vitality will be assessed using thermal and electric pulp sensibility tests

  8. Assessment of pulp vitality [12 months]

    Pulp vitality will be assessed using thermal and electric pulp sensibility tests

  9. Assessment of root development [1 month]

    Continued root development will be assessed using cone beam computed tomography (CBCT) and compared with the contra-lateral healthy tooth

  10. Assessment of root development [3 months]

    Continued root development will be assessed using cone beam computed tomography (CBCT) and compared with the contra-lateral healthy tooth

  11. Assessment of root development [6 months]

    Continued root development will be assessed using cone beam computed tomography (CBCT) and compared with the contra-lateral healthy tooth

  12. Assessment of root development [12 months]

    Continued root development will be assessed using cone beam computed tomography (CBCT) and compared with the contra-lateral healthy tooth

  13. Assessment of the size of periapical radiolucency [1 month]

    Size of the lesion will be assessed using the periapical index score. The PAI provides an ordinal scale of 5 scores ranging from 1 (healthy) to 5 (severe periodontitis with exacerbating features).

  14. Assessment of the size of periapical radiolucency [1 month]

    Size of the lesion will be assessed using Cone Beam Computed Tomography (CBCT).

  15. Assessment of the size of periapical radiolucency [3 months]

    Size of the lesion will be assessed using the periapical index (PAI) score. The PAI provides an ordinal scale of 5 scores ranging from 1 (healthy) to 5 (severe periodontitis with exacerbating features).

  16. Assessment of the size of periapical radiolucency [3 months]

    Size of the lesion will be assessed using Cone Beam Computed Tomography (CBCT).

  17. Assessment of the size of periapical radiolucency [6 months]

    Size of the lesion will be assessed using the periapical index (PAI) score. The PAI provides an ordinal scale of 5 scores ranging from 1 (healthy) to 5 (severe periodontitis with exacerbating features).

  18. Assessment of the size of periapical radiolucency [6 months]

    Size of the lesion will be assessed using Cone Beam Computed Tomography (CBCT).

  19. Assessment of the size of periapical radiolucency [12 months]

    Size of the lesion will be assessed using the periapical index (PAI) score. The PAI provides an ordinal scale of 5 scores ranging from 1 (healthy) to 5 (severe periodontitis with exacerbating features).

  20. Assessment of the size of periapical radiolucency [12 months]

    Size of the lesion will be assessed using Cone Beam Computed Tomography (CBCT).
