Persistent discomfort after root canal therapy may indicate three root canals in mandibular premolars. This study highlights two cases of successful root canal treatment in lower premolars with three canals, emphasizing careful examination.

Area of Science:

  • Dentistry
  • Endodontics
  • Oral Anatomy

Background:

  • Root canal therapy aims to treat infected or inflamed pulp tissue within the tooth's root canal system.
  • Mandibular premolars typically present with one or two root canals, but anatomical variations can occur.
  • Persistent postoperative discomfort following endodontic treatment can signal undiagnosed canal anatomy.

Observation:

  • This paper details two clinical cases of mandibular premolars requiring root canal treatment.
  • Both cases involved mandibular premolars (one first, one second) with an unusual three-canal configuration.
  • Radiographic and clinical examinations were crucial in identifying the complex root canal anatomy.

Findings:

  • Successful root canal treatment was achieved in both cases despite the presence of three canals.

  • The study confirms that mandibular premolars can possess three root canals.
  • Accurate diagnosis of root canal morphology is essential for effective endodontic outcomes.

    • Implications:

    • Clinicians should consider the possibility of three root canals in mandibular premolars during endodontic diagnosis and treatment planning.
    • Thorough radiographic interpretation and clinical assessment are vital to avoid missing accessory canals.
    • Recognizing and treating all canals can improve the success rate of root canal therapy and reduce treatment failures.
