A maxillary central incisor having two root canals geminated with a supernumerary tooth

Area of Science:

• Dentistry
• Endodontics
• Oral Surgery

Background:

• Gemination, a developmental anomaly, involves a single tooth bud attempting to divide, resulting in a partially or completely joined tooth.
• Supernumerary teeth, or hyperdontia, are extra teeth that develop in the dental arch.
• Combined gemination and supernumerary teeth present unique diagnostic and therapeutic challenges in endodontics.

Observation:

• A patient presented with labial swelling and was referred for endodontic evaluation of a maxillary left central incisor.
• Clinical and radiographic examinations revealed a geminated tooth with an associated supernumerary tooth.
• The affected maxillary incisor exhibited two roots and three distinct root canals.

Findings:

• Detailed examination of the cleaned root canals using a rubber base impression confirmed the presence of three canals.
• Crucially, the examination revealed no perforation or communication with a potential radicular groove within the tooth.
• This finding is significant for successful endodontic treatment planning and execution.

Implications:

• This case highlights the importance of thorough clinical and radiographic assessment for diagnosing complex dental anomalies like gemination with supernumerary teeth.
• Successful endodontic treatment of such complex root canal anatomy is achievable with meticulous technique.
• Understanding and managing these anomalies is crucial for preserving tooth function and preventing complications.
