Assessing healing patterns in dental microsurgery for persistent infections

A 2D and 3D Radiographic Assessment of the Healing Pattern Associated With Conventional and Piezoelectric Periradicular Endodontic Microsurgery

Not applicable Interventional King Abdullah University Hospital · NCT06031792

What this trial studies

This study evaluates the healing patterns associated with two types of endodontic microsurgery: conventional and piezoelectric techniques. A total of 44 patients with persistent symptoms after root canal treatment will be randomly assigned to one of the two surgical approaches. Preoperative and postoperative imaging will be conducted using digital radiographs and cone beam computed tomography (CBCT) to assess healing outcomes. Additionally, histological analysis will be performed on excised root tips to examine bacterial presence and tissue reactions.

Who should consider this trial

Good fit: Ideal candidates are medically fit individuals aged 18-65 with periodontally healthy teeth that have undergone root canal treatment.

Not a fit: Patients with active systemic diseases, emotional distress, or those with teeth deemed non-restorable will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment outcomes for patients with persistent apical periodontitis.

How similar studies have performed: While there is limited evidence on the use of piezoelectric techniques in endodontics, similar studies have shown promising results with conventional microsurgery approaches.
