OBJECTIVES: The aim of this study was to characterize the histomorphometric features of subgemmal neurogenous plaques (SNPs) to better understand their relationship to surrounding microanatomy included in the tissue biopsy samples of the tongue. STUDY DESIGN: A 12-year retrospective study on the files of 3 oral pathology centers yielded 28 SNPs. Hematoxylin and eosin-stained sections were used for histologic analysis, and immunohistochemical staining for S100 protein was performed to better characterize the neural structures...

OBJECTIVES: Alveolar ridge and vertical augmentations are challenging procedures in dental implantology. Even material blocks with an interconnecting porous system are never completely resorbed. Shell techniques combined with autologous bone chips are therefore the gold standard. Using biopolymers for these techniques is well documented. We applied three-dimensional (3-D) techniques to create an individualized bending model for the adjustment of a plane biopolymer membrane made of polylactide...

OBJECTIVES: To assess how often patients receive dental implants after mandibular resection for benign neoplasms and to determine barriers to completion of functional reconstruction. STUDY DESIGN: This was a retrospective cohort study of patients who underwent resection for benign mandibular neoplasms between 2005 and 2014. Demographic variables included age, sex, and race. Outcome variables include rates of implant placement, implant restoration, and reasons for not having implants...

BACKGROUND: Research using magnetic resonance imaging analysis has shown that internal temporomandibular joint derangement is associated with significantly greater horizontal condylar angle. However, the association between osteoarthritic (OA) bony changes as shown on computed tomography and horizontal condylar angle has never been evaluated. OBJECTIVE: To investigate the relationship between mandibular condylar angle and OA degenerative changes. STUDY DESIGN: This is a retrospective study using cone beam computed tomography images and reports from 60 patients with unilateral OA degenerative changes and 43 control patients with no OA-affected joints...

OBJECTIVE: The aim of the study was to evaluate the image quality of a photostimulable phosphor (PSP) plate system to determine if image degradation has occurred after a number of clinical uses. STUDY DESIGN: Twenty DIGORA Optime PSP plates (Soredex Orion Corp., Helsinki, Finland) were imaged throughout clinical use. Image quality was assessed by using spatial and contrast resolution through the use of the dental radiographic phantom designed for the Nationwide Evaluation of X-Ray Trends surveys of 1993 and 1999...

OBJECTIVE: The aim of this study was to investigate the expression of human leukocyte antigens (HLAs) G and E and programmed death-ligand 1 (PD-L1) in oral osteosarcoma (OO) (n = 13). The relationship between the expression of these molecules and histologic grading and metastasis was also evaluated. STUDY DESIGN: HLA-G, HLA-E, and PD-L1 were identified by immunohistochemistry. Samples of normal bone tissue (n = 6) were used as controls. The sections were evaluated using a semiquantitative scoring system with an immunoreactive score, where a score of 0 was considered absent, ≤2 was low, and >2 was high expression...

OBJECTIVE: Oral pulse granuloma (OPG) is an oral inflammatory lesion characterized by the presence of hyaline rings with numerous multinucleated giant cells. The etiopathogenesis of this lesion is thus far unclear, as is the composition of the hyaline rings. Our aim was to investigate whether the hyaline rings contain cellulose. STUDY DESIGN: Using a newly developed staining method for cellulose, we studied 18 histologic samples diagnosed as OPG, in addition to 3 samples originally diagnosed as "normal" foreign body reactions...

Dentin dysplasia (DD) is a rare developmental dentin disorder that causes root malformation. It is divided into radicular DD type 1 (DD-1) and coronal DD type 2 (DD-2). Recently, a new entity causing localized root malformation of permanent first molars that resembles DD-1b has been described as molar-incisor malformation (MIM). We report and compare 4 new cases that exhibit similar clinical, histologic, and radiographic features to the new entity, MIM. We believe MIM and our 4 cases to be the same entity, which is nonhereditary and, because of the isolated but bilaterally symmetric pattern of involvement, may be caused by a short-duration environmental insult that disrupts normal development/function of Hertwig's epithelial root sheath...

OBJECTIVE: The aim was to study the association between microflora and medication-related osteonecrosis of the jaw (MRONJ) by using culture-independent molecular techniques to detect bacteria in necrotic bone lesions. STUDY DESIGN: Included were 18 consecutive patients with MRONJ, 10 with osteoporosis and 8 cancer patients. Bone biopsies were retrieved from the center of the necrotic bone and from visually healthy bone, and 16 S rRNA gene fragments from bacterial DNA were amplified with polymerase chain reaction...

BACKGROUND: The purpose of this study was to investigate the feasibility of postoperative concomitant chemoradiotherapy (CRT) with cisplatin (CDDP), and compare the prognosis in 3 groups-without postoperative therapy (S-only), with radiotherapy (RT) alone (S+RT), and with CRT (S+CRT)-in oral squamous cell carcinoma (OSCC) patients at high risk of recurrence. METHODS: Clinicopathologic data and treatment modality were investigated. Endpoints evaluated were locoregional control (LRC), relapse-free survival, overall survival (OS), and type of recurrence...

REVIEW
Ravleen Nagi, Deepa Jatti Patil, Shashikant Sahu, Supreet Jain, Giridhar S Naidu
Botulinum toxin is a polypeptide protoxin synthesized by Clostridium botulinum that results in localized reduction of muscle activity by inhibiting acetylcholine release at the neuromuscular junction. In 2004, the US Food and Drug Administration approved its application in the treatment of various medical conditions, such as facial wrinkles, strabismus, cervical dystonia, blepharospasm, and hyperhidrosis. Later, its application extended to improving dental esthetics and gummy smile. It was found to be a safe and effective alternative to medical therapy to treat various head and neck disorders that have a neurologic component...

OBJECTIVE: Surgical margin status is an important prognostic factor in oral squamous cell carcinoma. The primary aim of the surgeon is to achieve a microscopically complete surgical resection during initial surgery. As there are no definite guidelines, a few surgeons use frozen section (FS) for margin assessment whereas others use gross examination (GE). STUDY DESIGN: This is a retrospective analysis of prospectively collected data from the electronic medical records of 435 oral cavity cancer patients...

PURPOSE: The cone beam computed tomography (CBCT) images of 2 closed treatments are compared for intracapsular condylar fractures (ICFs) to learn whether splint treatment could promote better radiologic outcomes. PATIENTS AND METHODS: Fifty-four patients with 60 sides of ICF were divided into 2 groups. In the control group (C-group), patients had a liquid diet for 1 month. In the trial group (T-group), patients wore splints with anterior elastic traction. Local CBCT images of the temporomandibular joint were obtained at T0 (mean 8...

OBJECTIVE: This study aims to analyze the expression of T-cell receptor γ chain alternate reading frame protein (TARP) in salivary adenoid cystic carcinoma (SACC) and its distant metastases and to investigate its influences on the development and progression of SACC. STUDY DESIGN: TARP expression was analyzed in 50 primary SACCs, 13 specimens of metastatic adenoid cystic carcinoma of salivary gland origin, and 20 noncancerous tissues around SACC via immunohistochemistry...

OBJECTIVE: This study evaluated the stress distribution of the sliding plate (SP) and conventional miniplate (CM) fixation techniques of a sagittal split ramus osteotomy (SSRO) using 3-dimensional (3-D) finite element analysis. STUDY DESIGN: Four 3-D finite element models according to the number and shape of screw holes in the plate were simulated, and the von Mises stress was analyzed: SP with 2 round and 2 oval holes (SP-2 R2 O), SP with 2 round and 1 oval holes (SP-2 R1 O), CM with 4 round holes (CM-4 R), and CM with 3 round holes (CM-3 R)...

OBJECTIVE: To determine whether there was any difference in the clinical and pathologic features, management, and survival outcomes based on tumor site for salivary adenoid cystic carcinoma (ACC). STUDY DESIGN: This study is a retrospective chart review of 63 salivary ACC patients. These patients were subclassified into 2 groups, the minor salivary glands group (MiSGG) and the major salivary glands group (MaSGG). RESULTS: With a median follow-up time of 69...
