BackgroundDentists may choose to integrate intraoral scanners (IOSs) into their practices, but there are many different IOS technologies and system generations from, posing a challenge for dentists who want invest in them.MethodsA survey of use rates, advantages, satisfaction, training was developed deployed through Qualtrics the 968 members American Dental Association Clinical Evaluators (ACE)...

Trochlear nerve schwannoma without neurofibromatosis is extremely rare. To our knowledge, only 31 surgical cases have been reported to date, and only 2 cases of trochlear nerve schwannoma with intratumoral hemorrhage have been reported. None of those cases presented with persistent hiccups. We report the case of a 44-year-old man with trochlear nerve schwannoma associated with intratumoral hemo...

Intraspinal schwannomas localized in the sacrum are relatively infrequent, accounting for 1-5% of all spinal axis schwannomas. They frequently grow to considerable size before detection; hence, the term giant sacral schwannoma. Sacral schwannomas arise from the sacral nerve roots. The diagnosis of schwannomas in the spinal canal is difficult because of their slow growth, often resulting in exte...

Schwannoma is a rare tumor of neural crest cell origin. Most schwannomas occur in the head, neck, stomach or limbs, with a few cases occurring in the retroperitoneal space. A 30-year-old Taiwanese woman presented with a 1-week history of left anterior chest discomfort and left flank pain. The laboratory findings and endocrine studies were all within normal limits. Chest X-ray revealed masses in...

Gastrointestinal schwannomas are uncommon stromal tumors of the intestinal tract and colon schwannomas are extremely rare. We report a rare case of ascending colon schwannoma with associated synchronous adenocarcinoma of the sigmoid colon. A 68-year-old man presented with a 20-day history of bleeding per rectum. Colonoscopy revealed a mass of 4.2 cm in diameter with endoluminal protrusion in th...

The purpose of this study was to compare the internal gap between CAD/CAM palladium-silver crowns and cast gold crowns generated from intraoral digital versus conventional impressions and to determine the clinical acceptability. Nickel-chrome master dies were made from the prepared resin tooth with the conventional impression method (n = 40). For ICC (Intraoral, CAD/CAM) group, 10 intraoral dig...

Schwannoma is a benign encapsulated nerve sheath tumor composed of Schwann cells, that may arise anywhere along the course nerve. Cutaneous schwannomas, associated with peripheral nerves, usually present as slow-growing well-circumscribed nodule, localized in dermis or subcutaneous tissue. They are generally asymptomatic; however, they become painful by nervous compression. Since clinical signs...

Stereotactic Radiosurgery has been widely utilized for the treatment of intracranial lesions, and this paper presents our experience in treating schwannomas Bangladesh. This case series was described to present institutional procedural technique adapted using stereotactic (SRS) by Linear accelerators. since starting radiosurgery program March 2019, we have treated three patients schwannoma. Two...

OBJECTIVE Stereotactic radiosurgery for vestibular schwannoma entails uncertain long-term risk of tumor recurrence and delayed cranial neuropathies. In addition, the underlying histopathologic changes to the tumor bed are not fully characterized. We seek to understand the clinical and histologic features of recurrent vestibular schwannoma after stereotactic radiation therapy. STUDY DESIGN Ret...

Aim: This study aims to evaluate the difference between depth data from an intraoral cone and a conventional irradiation tube calculated using a treatment planning system (TPS), and that measured using an intraoral cone for electron radiotherapy. Background: A TPS is only compatible with conventional irradiation tubes. However, such systems are not suitable for determining dose distributions wh...
