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.

Long-term clinical evaluation and SEM analysis of the e-PTFE and titanium membranes in guided tissue regeneration.

Aim: This study aimed to evaluate clinical outcomes of titanium membrane and compare these findings with clinical outcomes of e-PTFE membrane, and to investigate the effect of bacterial contamination on both membranes with SEM during long-term healing.

Results: Sixteen titanium and sixteen e-PTFE membranes were surgically placed adjacent to periodontally involved teeth. Seven titanium and 8 e-PTFE membranes were exposed between 4 and 6 weeks.

Aggressive fibromatosis of the oropharynx: a multidisciplinary approach to a benign disease.

We present the case of a 23-year-old woman with aggressive fibromatosis of the oropharynx that was initially treated elsewhere as a peritonsillar abscess. We discuss the characteristics of this rare tumor and review the literature, stressing the importance of postoperative follow-up for peritonsillar abscesses to avoid missing other important diagnoses, such as the one described here.

Pain perception and anxiety during scaling in periodontally healthy subjects.

Background: Dental pain, anxiety, and fear may result in avoiding dental treatment. In this study, we aimed to evaluate patients' pain perception during scaling and its relationship with dental anxiety.

Methods: One hundred thirteen patients (72 women and 41 men; mean age, 35.

The accuracy of computer-assisted surgical planning in soft tissue prediction following orthognathic surgery.

Background: The purpose of the present study was to evaluate the accuracy of a computer-assisted imaging system in predicting the soft tissue response following orthognathic surgery.

Methods: The study sample consisted of 11 adult patients with a mean age of 23.5 years.

Subcutaneous emphysema after dental treatment: a case report.

Subcutaneous emphysema is the condition in which air or other gases penetrate the skin and submucosa causing soft-tissue distention. This type of emphysema may be traumatic, iatrogenic or may occur spontaneously. This report describes the youngest case of subcutaneous emphysema related to dental treatment that has been documented to date.

Immediate mechanical stability of sagittal split ramus osteotomy fixed with resorbable compared with titanium bicortical screws in mandibles of sheep.

Ten fresh mandibles from adult sheep were stripped of all soft tissues and sectioned in the midline. We did sagittal split osteotomies and 5 mm advancement on all the 20 hemimandibles. Ten hemimandibles were fixed with three 2.

Distraction osteogenesis of basal mandibular bone for reconstruction of the alveolar ridge.

Alveolar distraction is being used increasingly for alveolar bone reconstruction in patients with severe mandibular defects. When there has been total loss of alveolar bone, distraction of the mandibular basal bone is necessary. Distraction osteogenesis is considerably more challenging in mandibular basal bone than in alveolar bone.
