A Stepwise Approach to Managing Bilateral Maxillary Sinus Tracts: A Case Report.

Area of Science:

• Dentistry
• Endodontics
• Oral Pathology

Background:

• Intraoral sinus tracts can present rarely, often posing diagnostic challenges.
• Differentiating endodontic infection from vertical root fracture (VRF) is crucial for appropriate management.
• Odontogenic infections require precise diagnosis and effective treatment to prevent complications.

Purpose of the Study:

• To report a rare case of bilateral intraoral sinus tracts of odontogenic origin.
• To highlight the diagnostic difficulties in distinguishing endodontic infection from VRF.
• To present the successful management of such a case using nonsurgical root canal retreatment.

Main Methods:

• A case report of a patient presenting with bilateral intraoral sinus tracts.
• Diagnostic evaluation including clinical examination and radiographic assessment.
• Management involved single-visit nonsurgical root canal retreatment of the affected maxillary molar.

Main Results:

• The patient presented with bilateral intraoral sinus tracts associated with a maxillary right first molar.
• Initial diagnosis was challenging, necessitating differentiation between endodontic infection and VRF.
• Nonsurgical root canal retreatment led to complete resolution of sinus tracts and radiographic healing within nine months.

Conclusions:

• Bilateral intraoral sinus tracts of odontogenic origin, though rare, can be successfully managed with endodontic therapy.
• Nonsurgical root canal retreatment is an effective treatment option for complex odontogenic infections.
• Prompt and accurate diagnosis is essential for successful outcomes in managing intraoral sinus tracts.
