Scanning electron microscopy and histologic analysis of an apexification "cap": a case report

Area of Science:

• Dentistry
• Endodontics
• Dental Traumatology

Background:

• A maxillary central incisor experienced trauma, followed by apexification and internal thermocatalytic bleaching.
• The tooth later sustained a horizontal fracture at the cementoenamel junction, leading to extraction.

Observation:

• Following extraction, the root apex was subjected to histological examination and scanning electron microscopy (SEM).
• An apexification 'cap' was identified at the root apex.

Findings:

• The observed apexification cap exhibited unusual anatomical characteristics and structure.
• Histological and SEM analyses provided detailed insights into the cap's morphology.

Implications:

• This finding contributes to understanding the complex outcomes of apexification procedures.
• Further research may elucidate the clinical significance of such unique apexification cap structures in dental traumatology.
