RESUMEN
INTRODUCTION: The knowledge of root canal morphology and the existing anatomical variations is essential for successful endodontic therapy. METHODS: This report presents an extraordinary case of unusual tooth morphology involving the bilateral existence of 7 maxillary and mandibular first and second molars with a single root and a single canal in a patient. RESULTS: Endodontic retreatment of the affected teeth #15, #19, and #18 was performed. Cone-beam computed tomography (CBCT) images confirmed our diagnostic and therapeutic measures after endodontic management of the teeth. CONCLUSIONS: This morphologic variation has not been reported in the literature. The availability of 3-dimensional images further provided the opportunity for the precise description of the anatomy of 7 maxillary and mandibular molars with single roots and single canals.

A 40-year-old female patient with noncontributory medical history presented to the postgraduate clinic of the Department of Endodontology, Aristotle University of Thessaloniki, Greece. Her chief complaint was a gradually increasing swelling in the left side of her maxilla, during the preceding 2 months. After clinical examination, the radiologic and computerized tomographic scan examinations revealed the presence of a radiopaque foreign material in contact with the apex of tooth #22, confined within the limits of a radiolucent area. On dental anamnesis and after communication with her dentist, it was concluded that calcium hydroxide was deliberately extruded for the healing of the large lesion. The patient was scheduled for periapical surgery. The histopathologic features of the lesion revealed the presence of a periapical cyst and the absence of foreign body giant cells. After an observation period of 1 year, healing was uneventful.

A 25-yr old female with a 12-month history of orofacial trauma was referred to us with acute pain with positive percussion of the left mandibular first premolar and swelling in the left-posterior mandibular area. The diagnosis was pulpal necrosis with acute apical abscess. Both preoperative and length determination radiographs revealed a semi-opaque area on the root of the first premolar that was later identified as a residual fragment of windshield left in the soft tissues. Thorough medical record, clinical and radiographic examination may be helpful in the detection of foreign bodies in the orofacial region.
