Abstract:

Introduction: Gingival retraction is the withdrawal of the marginal gingiva away from the tooth. This procedure creates a space between the prepared tooth and the gingival tissues to catch more fine details of the impression material. The most common retraction device used in clinical practice is the retraction cord. Aim: The study aims to evaluate the tensile strength of retraction cords designed with different braiding technology. Materials and methods: A total of 150 experimental units were studied. They were divided into 3 groups of 50 each according to the type of retraction cord (Ultrapa

Abstract:

Introduction: Spinal cord trauma can cause partial or total damage to the brain's and spinal cord's connection. The effects of spinal cord injury will affect motor function even if there is a severe injury, and in a longer duration, it will cause death. Medulla spinalis retraction can cause clinical abnormalities, especially in motor function. Methods: This study consisted of three groups of male Wistar rats (Rattus norvegicus). Each group was subjected to 15%, 25% and 37.5% retractions for 1 minute, 3 minutes and 5 minutes, respectively. After that, an assessment was carried out with the foot

Introduction: Tooth loss affects a person's appearance and health, impacting their quality of life. Teeth play an essential role in chewing and aesthetics, particularly the anterior teeth. Dental trauma such as fractures can affect appearance and psychology, reducing self-confidence. Currently, aesthetics is a top priority in dental care. Tooth loss leads to complex oral problems, thus missing teeth need to be replaced with dentures.

Abstract:

Axotomy in the CNS activates retrograde signals that can trigger regeneration or cell death. Whether these outcomes use different injury signals is not known. Local protein synthesis in axon tips plays an important role in axon retraction and regeneration. Microarray and RNA-seq studies on cultured mammalian embryonic or early postnatal peripheral neurons showed that axon growth cones contain hundreds to thousands of mRNAs. In the lamprey, identified reticulospinal neurons vary in the probability that their axons will regenerate after axotomy. The bad regenerators undergo early severe axon ret

Remodeling of cytoskeleton structures, such as microtubule assembly, is believed to be crucial for growth cone initiation and regrowth of injured axons. Autophagy plays important roles in maintaining cellular homoeostasis, and its dysfunction causes neuronal degeneration. The role of autophagy in axon regeneration after injury remains speculative. Here we demonstrate a role of autophagy in regulating microtubule dynamics and axon regeneration. We found that autophagy induction promoted neurite outgrowth, attenuated the inhibitory effects of nonpermissive substrate myelin, and decreased the for

The cytocompatibility of ten astringent-based chemical retraction agents: Gingiva Liquid, Alustin, Racestypine, Orbat sensitive, Astringedent®, Alustat, Hemostat, Racécord, Gel cord and ViscoStat®, in dilutions of 1 : 10 and 1 : 20, with human gingival fibroblasts was investigated. The MTT assay was performed to determine oxidoreductive mitochondrial

Abstract:

The video demonstrates an operative approach to a recurrent cervical anaplastic ependymoma. MYCN-amplified anaplastic ependymomas are locally aggressive, recurrent, and have a high risk of iatrogenic injury. In this case, the patient presented with local, aggressive tumor expansion, arachnoid adhesions, and pial invasion ventral to the spinal cord. Subcapsular decompression minimized cord retraction from a dorsal approach. Removal of the tumor capsule was guided by bipolar stimulation paired with neuromonitoring. Local gross-total resection was achieved, and the patient had a postoperative imp

Abstract:

Background and Aims: This randomised study investigated whether microcuff endotracheal tubes (ETT) reduce postoperative complications compared to wire-reinforced ETT in patients undergoing anterior cervical discectomy and fusion (ACDF). Methods: In total, 120 patients were randomly assigned to receive either a microcuff ETT (Group M) or a wire-reinforced ETT (Group W) during surgery. Intraoperative cuff pressure changes due to retractor use were noted. Postoperative complications such as vocal cord palsy and airway oedema were observed at extubation, and hoarseness, sore throat, dysphagia, and

Abstract:

Abstract Ventral spinal tumors are surgically challenging because the tumor resection should minimize spinal cord and nerve root manipulation to minimize morbidity, while providing access to a complete tumor resection. The CO2 laser has been useful in resection of central nervous system tumors, but little is described about the method used to resect spinal tumors.1 This video demonstrates the removal of a ventral cervical spinal meningioma using the CO2 laser. A 62-yr-old man presented with progressive paresthesias, gait instability, and urinary frequency. A 1-cm intradural extramedullary mass

Abstract:

Spinal meningiomas represent 25%–45% of intradural spinal tumors and are commonly seen in the thoracic spine. Ventral midline spinal meningiomas in the thoracic spine are challenging lesions to resect given their location in relation to the spinal cord. Resection for symptomatic or growing lesions requires adequate bone removal to limit retraction of the spinal cord. Surgical adjuncts such as intraoperative navigation, robotics, and ultrasound can improve the efficiency of and safety for resection of these lesions. The authors present a case of a complete resection of a ventral thoracic mening

Abstract:

This article aims to introduce a novel full-endoscopic anterior cervical discectomy and fusion (ACDF) procedure to treat cervical myelopathy. Adoption of endoscopic anterior cervical procedures has been lagging due to safety concerns and the necessity of placing an interbody cage. We have developed novel instrumentation and a modified percutaneous anterior cervical approach that allows a safe and reproducible full-endoscopic ACDF. Specially designed retractor blades facilitate percutaneous placement of a zero-profile cervical interbody cage. A 64-year-old male patient presents with chronic nec

Abstract:

Reinnervation of the posterior cricoarytenoid muscle (PCA) should provide vocal cord abduction on inspiration, and passive adduction to enable phonation. Previous investigators have shown that reinnervation is possible, but results have not been clinically encouraging. When reinnervation was successful, the question remained whether it was provided by the transplanted nerve or by the ingrowth of adjacent nerves. In this study the phrenic nerve was transplanted directly into the PCA in a series of 12 cats. Fibrin glue was used to overcome nerve trauma and to prevent retraction of the nerve from

Since the discovery of making impression for fixed protheses directly in the mouth, impresions material or negativeform resembling the tooth and surrounding structures are used to get a working model. Impression received must bea real replica of a tooth that has been prepared. The impressions that are not clear between the borders withgingival preparation are the common cause of failure when impression was made. Good impression is one of thesupporting factors to produce a fixed protheses which can well adapted to the tooth tissue that does not cause leaksand dissolve the cement. So the tooth i

✓ This report describes a technique for exposing the ventrolateral quadrant of the spinal cord through an extended posterolateral approach that can be used in both cervical and thoracic regions. The surgical technique includes the following: 1) a midline skin incision with a transverse extension at the level of pathology; 2) unilateral division and retraction of the paraspinous muscles; 3) laminectomy and unilateral removal of facets and pedicles; 4) dural incision over the dorsal root entry zone; 5) multilevel division of the ipsilateral dentate ligaments; and 6) elevation and rotation of the
