introduction: the aim of this in vitro study was to compare the canal transportation of two single-file engine-driven systems, neoniti and reciproc, using cone-beam computed tomography (cbct). methods and materials: forty-five non-calcified roots with mature apices and apical curvature of 15-30 degrees were selected from extracted human maxillary molars for this study. samples were randomly div...

This article describes a case of a 13-year-old girl with single-level calcified cervical disk herniation. The patient was treated conservatively for a symptomatic intervertebral calcification that caused neurological compression, and the data were reviewed retrospectively. Previous reports have shown that the natural history of the disease is self-limiting with a benign course and an excellent ...

Localization of calcified canals has always been a challenge in the field of endodontics. The following report of three cases describes a technique for the identification and negotiation of obliterated canals by use of cone beam computed tomography (CBCT) intraoperatively. Canal orifices could not be found clinically in all three cases. Gutta-percha points were placed and compacted at the posit...

Acquired external auditory canal atresia is a rare complication of chronic inflammatory otitis, and is generally fibrous or soft tissue in nature. Here, we present the first reported case of heterotopic ossification within chronic fibrosing otitis externa in a 25-year-old male patient with a childhood history of granular myringitis and failed tympanoplasty. A calcified mass was demonstrated adj...

The myelographic, CT, and MR findings of a rare localized primary bone amyloidoma causing upper thoracic spinal cord compression are presented. Imaging showed a large, calcified mass centered in the posteromedial portion of the left second rib that invaded the second thoracic vertebra and the spinal canal.

The yellow ligament, or Ligamentum flavum, is the ligament that connects lamina arches of two adjacent vertebrae in spine [1,2]. This and has elasticity [3,4]. flavum ossification an uncommon cause pressure on cervical cord [3] [5-7]. commonly occurs thoracic which can myelopathic symptoms patient [8,9]. main this problem unknown, but it when soft tissue calcified causes narrowing spinal canal ...

Transverse testicular ectopia (TTE) is a rare anomaly in which both testis descend through a single inguinal canal and enter to same hemiscrotum. To the best of our knowledge, we are reporting a new variant of TTE with right inguinal hernia with bilateral pyocoele. In this case, both testes descend separately through corresponding inguinal canal and present in single right scrotum. There is no ...

STUDY DESIGN Case series and review of the literature. OBJECTIVE To review the management of giant calcified disks in our large cohort and compare with the existing literature. We discuss our surgical technique. METHODS Twenty-nine cases of herniated thoracic disk between 2000 and 2013 were reviewed. Eighteen patients were identified as having giant calcified thoracic disks, defined as diff...

A 32-year-old male patient came to the department of oral medicine and radiology with a chief complaint of discoloured teeth in upper front tooth region since 2 years. He gave no history of pain and a history of fall 4 years ago. Past medical and dental history were noncontributory. Intraoral examination revealed yellowish discoloration of coronal aspect of left maxillary central incisor (Figur...
