NCT07314866

Brief Summary

This pilot clinical study evaluated the clinical, radiographic, and functional outcomes of autologous pulp transplantation combined with concentrated growth factor (CGF) in mature permanent teeth with pulp necrosis and periapical lesions. Treated teeth were followed for 12 months using clinical examination, electric pulp testing, and cone-beam computed tomography to assess pulp sensibility and periapical healing.

Outcome Measures

Primary Outcomes (1)

  • Number of Teeth With Periapical Healing Assessed by CBCT

    Periapical healing will be assessed using cone-beam computed tomography (CBCT). Healing will be defined as complete or partial resolution of periapical radiolucency and evidence of bone regeneration at the root apex compared with baseline CBCT images. Outcomes will be reported as the number of treated teeth demonstrating radiographic periapical healing.

    12 months

Secondary Outcomes (2)

  • Number of Teeth With Positive Pulp Sensibility Response Assessed by Electric Pulp Testing

    6 months and 12 months

  • Number of Teeth With Clinical Success

    Up to 12 months

Study Arms (1)

CGF-Enhanced Autologous Pulp Transplantation

EXPERIMENTAL

Participants received autologous pulp transplantation harvested from extracted third molars combined with concentrated growth factor as a regenerative endodontic treatment.

Procedure: Autologous Pulp Transplantation With Concentrated Growth Factor

Interventions

Autologous pulp tissue harvested from extracted third molars was transplanted into disinfected root canals of mature necrotic permanent teeth. Concentrated growth factor prepared from the patient's venous blood was applied as a biologically active scaffold to support cell survival, angiogenesis, and tissue integration. The procedure was completed with coronal sealing using mineral trioxide aggregate.

Eligibility Criteria

Age15 Years - 40 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Systemically healthy patients aged 15 to 40 years.
  • Mature permanent single-rooted teeth with clinical and radiographic diagnosis of pulp necrosis (or irreversible pulpitis with necrotic findings) associated with periapical radiolucency.
  • Probing depth \< 3 mm and no abnormal tooth mobility.
  • No previous endodontic treatment or apical surgery on the study tooth.
  • Availability of an autologous donor tooth (impacted or nonfunctional third molar indicated for extraction) to obtain pulp tissue.
  • Ability and willingness to attend follow-up visits and provide written informed consent.

You may not qualify if:

  • Systemic conditions that may impair healing (e.g., uncontrolled diabetes mellitus, autoimmune disease) or use of immunosuppressive therapy.
  • History of head and neck radiotherapy.
  • Pregnancy or lactation.
  • Poor oral hygiene or periodontal disease with probing depth ≥ 4 mm.
  • Teeth with root fracture, internal/external root resorption, severe canal calcification, or non-restorable crown destruction.
  • Inability to comply with follow-up schedule.
