Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

•Patients age ranges between 7 and 12 years at the time of enrolment including both genders. •Provision of informed consent by one parent or legal guardian. •At least one immature permanent anterior tooth diagnosed with pulp necrosis with or without periapical lesions. •Restorable teeth. •Compliant patient/parent. •Radiologic evidence of open apices (Teeth are considered immature when a minimum of 1 mm apical foramen width is evident)

Exclusion criteria

•Teeth with root fractures or split roots. •Presence of root resorptions. •Presence of periodontal pockets. •Developmental anomalies. •Presence of periapical radiolucency of more than 10 mm. •Tooth with class III mobility.

Treatment and study plan

Regenerative endodontic treatment with conventional blood clot technique.

Other

After local anesthesia, rubber dam isolation and access cavity preparation, pulp tissue extirpation/debridement, the root canal system is minimally instrumented. Copious irrigation is performed, gently with single-side vented needles. Canals are dried with paper points. Metapaste is injected as intracanal medication. At second session, check for absence of signs/symptoms. Copious gentle irrigation and drying of canals with paper points is done. Bleeding is created in root canal by over-instrumentation until bleeding is evident in the cervical portion of the canal. A lightly moistened sterile cotton pellet is placed into the canal, 3-4 mm apical to the CEJ, for 7-10 minutes to allow blood clot formation. Placement of MTA over the blood clot as a capping material. A 3-4 mm layer of glass ionomer is gently placed over the capping material. Followed by resin composite restoration.

Primary outcomes

  1. Radiographic assessment of root length by CBCT

    Time frame: Baseline (immediately post-operative), an 12 months post-operative.

    For all cases, CBCT was taken at a setting of 3-7 mA and 120 kVp and an exposure time of 9 s. Each scan was taken over 360º with a 0.3 mm voxel size. The root length was measured using the CBCT ruler to draw a line from the center point of the line connecting CEJ to the most apical point in the center of the root apex (proximally and facially). The percentage of increase in root length was calculated using this formula:

    (12 months value - preoperative value )/Preoperative value X 100%

  2. Radiographic assessment of diameter of apical foramen by CBCT

    Time frame: Baseline(immediately post-operative), and 12 months post-operative.

    Diameter of the apical foramen was measured using the CBCT ruler at the most apical points buccolingually at the sagittal (proximal) view of CBCT. It was also measured at the most apical points mesiodistally at the coronal (facial) view of CBCT. The percentage reduction of the apical diameter was calculated using this formula:

    ( preoperative value - 12-month value ) /Preoperative value *100%

  3. Radiographic assessment of root area by CBCT

    Time frame: Baseline (immediately post-operative), and 12 months post-operative.

    Radiographic root area (RRA) was measured using a method described by Flake et al using the polygon selection tool of CBCT. Below a straight line marking the CEJ, the root area was outlined from the surrounding periodontal environment. Then, the pulp space area was measured by the same method using the polygon tool by tracing the reference points surrounding the pulp space. Finally, RRA was calculated by subtraction of the pulp space area from the outer root area. These measurements were made at proximal and facial views of CBCT . The percentage increase in RRA was calculated using this formula:

    ( 12-month value - preoperative value )/Preoperative value X 100 %

  4. Radiographic assessment of size of periapical lesion by CBCT

    Time frame: Baseline (Immediately post-operative), and 12 months post-operative.

    Lesion size was measured by tracing the periphery of the lesion using the polygon tool of the CBCT from proximal and facial views of the CBCT. A closed polygon tool was used to delimit the border of the lesion to measure the area of the periapical lesion in (mm2).The percentage reduction of lesion size was calculated as follows:

    ( preoperative value - 12-month value ) /Preoperative value X 100 %

Secondary outcomes

  1. Clinical assessment of presence/ absence of pain

    Time frame: Baseline, 3 months, 6 months, and 12 months post operative.

    Assessment of symptoms of patient whether there is a pain or not in each follow up period.

  2. Clinical assessment of presence/ absence of mobility of teeth

    Time frame: Baseline, 3 months, 6 months, and 12 months post operative.

    Assessment of teeth whether they exhibit mobility or not

  3. Clinical assessment of presence/ absence of associated sinus tract or swelling.

    Time frame: Baseline, 3 months, 6 months, and 12 months post operative.

    Assessment of teeth whether they exhibit associated sinus tract or swelling or not

  4. Clinical assessment of presence/ absence of tenderness to palpation of adjacent soft tissues.

    Time frame: Baseline, 3 months, 6 months, and 12 months post operative.

    Assessment of teeth whether they exhibit tenderness to palpation of adjacent soft tissues or not

  5. Clinical assessment of presence/ absence of tenderness to percussion

    Time frame: Baseline, 3 months, 6 months, and 12 months post operative.

    Assessment of teeth whether they exhibit tenderness to percussion
