Primary diffuse large B-cell lymphoma of the mandible: A case report.

Introduction: Lymphomas are a heterogeneous group of malignant neoplasms of lymphocytes and their precursor cells. Lymphoma is seen 3.5% of all intraoral malignancies and is the second most common neoplasm after the squamous cell carcinoma in the head and neck region.

Intraligamentary and Supraperiosteal Anesthesia Efficacy Using a Computer Controlled Delivery System in Mandibular Molars.

Purpose: The purpose of this study was to compare pain, efficacy and postoperative complications of anesthesia in first primary mandibular molars anesthetized with either intraligamentary (IL) or supraperiosteal (SP) anesthesia using a computer-controlled delivery system (CCDS).

Study Design: This randomized, controlled-crossover, blind clinical trial was conducted with 90 children requiring bilateral extraction, pulpotomy or restorative treatment of first mandibular primary molars. A CCDS was used to deliver IL anesthesia to 1 deciduous tooth and SP anesthesia to the contralateral tooth in each patient.

Evaluation of prebent miniplates in fixation of Le Fort I advancement osteotomy with the finite element method.

The stability of segments after Le Fort I osteotomy first attracted the researcher's interest when the surgical concept was conceived. Prebent plates are the ultimate modification of plate systems in craniofacial surgery; they have two right angles and are available in different lengths for use in maxillary advancement surgery. For this research, cone-beam computed tomography (CBCT) images of a male patient were obtained and scanned, and a 3D maxillary bone was created.

Coronectomy in patients with high risk of inferior alveolar nerve injury diagnosed by computed tomography.

Purpose: Previous studies have suggested coronectomy as an alternative procedure to decrease the risk of inferior alveolar nerve (IAN) injury when there are high-risk findings observed on panoramic radiographs. However, the exact relation between the inferior alveolar canal and the roots is not obvious on 2-dimensional imaging. The aim of this study was to evaluate the success of coronectomy by comparing it with conventional extraction for the treatment of the patients who had clear IAN injury risks that were determined on 3 dimensions by computed tomography.

Alport syndrome: significance of gingival biopsy in the initial diagnosis and periodontal evaluation after renal transplantation.

Alport Syndrome (AS) is an important hereditary disorder affecting the glomerular basement membrane. Diagnosis of AS is based on the presence of hematuric nephropathy, renal failure, hearing loss, ocular abnormalities and changes in the glomerular basement membrane of the lamina densa. The aims of this case report were to show the changes in the gingival tissues in a patient with AS under therapy with cyclosporin-A after renal transplantation and to discuss the possible role of type IV collagen in gingival basal lamina as an alternative approach for the diagnosis of AS.
