BACKGROUND AND PURPOSE Steeper tapering of the cervical spinal canal as documented in recent studies is thought to have a role in the pathophysiology of Chiari malformation-associated syringomyelia. This study aimed to determine whether taper ratio of the cervical spinal canal differs between patients with distended and nondistended syringes. MATERIALS AND METHODS Seventy-seven adolescents (1...

BACKGROUND Detailed knowledge of cervical canal and transverse foramens' morphometry is critical for understanding the pathology of certain diseases and for proper preoperative planning. Lateral x-rays do not provide the necessary accuracy. A retrospective morphometric study of the cervical canal was performed at the authors' institution to measure mean dimensions of sagittal canal diameter (SC...

objectives: the main disadvantage of fiber posts is their low bond strength to root canal wall. the aim of the present study was to assess the effect of different root canal post space treatments on push-out bond strength of fiber posts to root dentin. materials and methods: after post space preparation in 40 endodontically treated human premolars, the teeth were randomly divided into four expe...

STUDY DESIGN Technique description and retrospective data analysis. PURPOSE To describe the technique of cervical kyphosis correction with partial facetectomies and evaluate the outcome of single-stage posterior decompression and kyphosis correction in multilevel cervical myelopathy. OVERVIEW OF LITERATURE Kyphosis correction in multilevel cervical myelopathy involves anterior and posterior...

Root canal treatment encompasses thorough cleaning and shaping of the canal. Cleaning is achieved through proper instrumentation and irrigation for debridement and dis­ infection of the root canal system in addition to creating a suitable shape for complete three dimensional obtura­ tion. Various irrigants and medicaments have been used for cleaning root canals with different results. These in­...

instrument fracture within the root canal during root canal treatment is an unwanted and frustrating complication. the fractured segment may hinder cleaning and shaping procedures with potential impact on prognosis of treatment. fracture of endodontic instrument often results from incorrect use or overuse. if breakage occurs clinically, the patient should be informed of the incident and conside...

Objective: Placental implants in the cervical canal may occur result patients with placenta previa that lead to bleeding after placental removal. Bleeding from can be stopped by inserting Cook Ripening Balloon. Case Presentation: A 31-week pregnant an was brought emergency clinic a complaint of vaginal bleeding, and active observed. Ultrasonography showed fetus fetal bradycardia previa. The pat...

Background: Hematometra is an uncommon disorder that can be caused by congenital or acquired structural obstruction of the cervical canal. Acquired cervical stenosis can develop due to surgical procedures performed on the uterus or cervix. Common symptoms associated with this disorder include amenorrhea or dysmenorrhea in premenopausal women, pelvic pain or pressure, urinary frequency and reten...

Introduction: Primary root canal treatment success depends on a number of variables, including debridement and disinfection of the root canal system to remove all bacteria and diseased pulpal and dentinal tissues. Complex root canal anatomy, such as concealed isthmuses, apical deltas and lateral canals, hinder this objective, making instrumentation of these regions nearly impossible. Recent adv...

BACKGROUND The sagittal diameter of the cervical spinal canal is of clinical importance in traumatic, degenerative, and inflammatory conditions. A small canal diameter has been associated with an increased risk of injury; however, there is a lack of reliable normative data on spinal canal diameters in different age groups in the United States population. The purpose of this study was to use dir...
