Repair of a perforating internal resorption: two case reports

Area of Science:

• Dentistry
• Endodontics
• Oral Surgery

Background:

• Internal resorption is a rare dental condition affecting permanent teeth, often asymptomatic and detected via radiographs.
• Causes include trauma, caries, or restorative procedures, potentially leading to tooth perforation into the periodontium.
• The standard treatment involves debridement, obturation, sealing perforations, and restoring tooth function.

Purpose of the Study:

• To present two distinct treatment modalities for repairing internal resorption with perforation.
• To compare conventional endodontic therapy with surgical intervention for managing internal resorption defects.

Main Methods:

• Case presentation detailing two methods for repairing internal resorption with perforation.
• Method 1: Conventional endodontic therapy under a microscope, followed by repair with mineral trioxide aggregate (MTA) for a lower right second premolar.
• Method 2: Surgical treatment for an upper right central incisor with internal resorption and perforation.

Main Results:

• Successful repair of internal resorption with perforation was achieved using both conventional endodontic therapy with MTA and surgical intervention.
• The choice of treatment was influenced by perforation size, location, and accessibility for repair.

Conclusions:

• Both nonsurgical (conventional endodontic therapy with MTA) and surgical approaches can effectively manage internal resorption with perforation.
• Treatment selection should be individualized based on specific clinical factors such as perforation characteristics and restorability.
