Endodontic therapy in a fused mandibular molar

Area of Science:

• Dentistry
• Endodontics
• Oral Surgery

Background:

• Tooth fusion is a rare developmental anomaly where two or more teeth develop from a single tooth germ.
• Mandibular third molar and distomolar fusion presents unique diagnostic and treatment challenges.
• Endodontic management is crucial for preserving the vitality and function of fused teeth.

Observation:

• A case of fusion between a mandibular third molar and a supernumerary fourth molar (distomolar) is presented.
• The fused teeth exhibited complex root anatomy, complicating endodontic access and instrumentation.
• Clinical and radiographic examinations were essential for diagnosis and treatment planning.

Findings:

• Successful endodontic treatment was performed on the fused mandibular third molar and distomolar.
• The root canal systems of both teeth were thoroughly cleaned, shaped, and obturated.
• Post-treatment evaluation confirmed the absence of periapical pathology and maintained tooth vitality.

Implications:

• This case highlights the importance of thorough radiographic interpretation in identifying dental anomalies.
• Endodontic treatment can be a viable option for managing fused teeth, preventing extraction.
• The successful management of this rare condition contributes to the understanding of endodontic procedures in complex dental anatomy.
