Cystic lesion caused by latex material.

Area of Science:

• Endodontics
• Oral Pathology
• Dental Materials

Background:

• Cystic lesions associated with teeth can complicate endodontic treatment.
• Refractory periapical lesions may require advanced diagnostic and surgical interventions beyond conventional endodontic therapy.

Purpose of the Study:

• To report the management of a refractory cystic lesion associated with a maxillary second premolar.
• To investigate the etiology of a persistent periapical lesion after initial endodontic treatment.

Main Methods:

• Conventional endodontic therapy was performed on the maxillary second premolar.
• Surgical intervention including cyst enucleation, biopsy, and apical surgery was conducted.
• Histopathological examination of the enucleated lesion was performed.

Main Results:

• Initial endodontic treatment led to incomplete healing of the cystic lesion.
• Histopathology revealed foreign latex material in the periapical tissue, suspected to be from a dental glove.
• Surgical treatment resulted in significant resolution of the lesion at the 1-year follow-up.

Conclusions:

• Refractory periapical cystic lesions may harbor unexpected foreign materials.
• Latex foreign material exposure can lead to persistent inflammatory responses and treatment failure in endodontics.
• Combined endodontic and surgical management, with thorough histopathological analysis, is crucial for refractory cases.
