Key Clinical message:
This case report examines a rare instance of bilateral sinus tracts of
dental origin in a 32-year-old female. The rarity of bilateral sinus
tracts without vertical root fractures emphasizes the need for accurate
diagnostic evaluation. This case highlights the importance of
considering dental origins in atypical sinus tract presentations.

Introduction
A longstanding odontogenic infection can lead to pus \RL formation,
which drains intra-orally or extra-orally through sinus tracts. Sinus
tracts can appear in various anatomical regions and have sometimes been
mistaken for epidermoid cysts, cystic acne, or salivary gland fistulas
(1). There have been reports of cutaneous fistulas (both unilateral and
bilateral) caused by dental origins (2, 3). Additionally, many nasal
sinus tracts have been documented (4-6).
Lesions in atypical locations can lead to misdiagnosis, unnecessary
treatments, and persistent symptoms or complications (7). Given the
limited literature on this topic, each case report adds valuable
insight. This report describes a case of bilateral sinus tracts in a
young female and reviews the relevant literature to provide a better
understanding of their causes and management. To our knowledge, this is
the first reported case of an alveolar bilateral sinus tract linked to a
maxillary first molar.
Case Presentation
This case report study is documented based on PRICE 2020 guidelines (8).
Also, according to the Declarations of Helsinki, all ethical
considerations have been observed. An endodontic specialist with 5 years
of experience, performed all treatment protocols in the endodontics
department of Mashhad Dental Faculty. Written and verbal informed
consent was obtained from the patient The patient also consented to
report the treatment results as a present study.
Case History/examination
A 32-year-old female presented with complaints of recurrent infections
and discharge from both sides of teeth, at the Endodontics Clinic of
Mashhad Dental School, Iran. The patient had been referred by a general
dentist who visited her two weeks before. She had been referred by a
general dentist who examined her two weeks prior. In the referral
report, the dentist noted signs of infection and a history of pus
drainage through the fistula in the past two months. Pre-operative
radiographs and clinical photographs of the initial condition and
treatment were provided by the referring dentist, as shown in Figure 1
