Abstract To compare masticatory muscle thickness in patients with temporomandibular disorders (TMDs) during rest and clenching, by body position, using ultrasonography. This prospective study included 96 TMD (67 females, 29 males; mean age: 40.41 ± 17.88 years): group 1, comprising 66 without bruxism (TMD_nonbruxer), 2, 30 concurrent (TMD_bruxer). In TMD, was correlated the presence of tinnitus, stiffness, sleep problems, psychological stress, restricted mouth opening. The masseter...

Facing the escalating threat of viruses worldwide, development efficient sensor elements for rapid virus detection has never been more critical. Traditional point-of-care (POC) sensors struggle due to their reliance on fragile biological receptors and limited adaptability viral strains. In this study, we introduce a nanosensor design receptor-free recognitions using near-infrared (NIR) fluorescent single-walled carbon nanotubes (SWCNTs) functionalized with poly(ethylene glycol)...

Abstract Objectives The purpose of this study was to confirm volume stability biphasic calcium phosphate ( BCP ) through the changes grafted over time by 3 D CT analyzing software program. Patients and Methods Fifteen patients, 16 sinuses who were scheduled a staged implantation sinus floor elevation SFE )–lateral window technique from 2009 2011 included in study. Of 15 eight male seven female (mean age 50.1). For augmentation, with local blood packed loosely into maxillary site covered...

ABSTRACT Background The purpose of this study was to identify the prevalence sialoceles and risk factors associated with their formation after parotidectomy. Methods We performed a retrospective analysis data from consecutive patients who underwent partial superficial parotidectomy parotid tumors. Demographic data, preoperative imaging results, operative variables, including tumor type, incision size, method parenchymal disruption were assessed. Results Twenty‐three 357 (6.4%) undergoing...

Eagle's syndrome is a disease caused by an elongated styloid process or calcified stylohyoid ligament. Eagle defined the disorder in 1937 describing clinical findings related to process, which one of numerous causes pain craniofacial and cervical region. The prevalence individuals with this anatomic abnormality adult population estimated be 4% 0.16% these reported symptomatic. usually characterized neck, throat, ear pain; pharyngeal foreign body sensation; dysphagia; upon head movement;...

A survey was performed to identify the level of mouthguard use, awareness, wearability issues and attitude toward among elite Korean Taewondo athletes.Survey questionnaires were given 152 athletes participating in Korea National Taekwondo team selection event for 2010 Guangzhou Asian Games. Questionnaires consisted three sections, reasons not wearing last section test acceptance on current when identified problems resolved. For analyzing difference response, χ(2) used significant (α) set up...

The objective of this study was to investigate the biologic effects enamel matrix derivative (EMD) with different concentrations on cell viability and genetic expression human gingival fibroblasts (HGF) zirconia surfaces.Immortalized were cultured (1) without EMD, (2) EMD 25 µg/mL, (3) 100 µg/mL discs. MTT assay performed evaluate proliferation activity SEM carried out examine cellular morphology attachment. mRNA collagen type I, osteopontin, fibronectin, TGF-β1 evaluated real-time...

Bisphosphonates are generally used as therapeutic agents for bone diseases. However, previous reports on bisphosphonates-related osteonecrosis of the jaw (BRONJ) demonstrated that inflammation triggers and worsens disease. Recently, polydeoxynucleotide (PDRN), an A2A receptor agonist, has been suggested treatment various diseases broadly studied its anti-inflammatory effect. The present study aimed to measure effect PDRN macrophage cells treated with zoledronic acid (ZA) lipopolysaccharide...

Abstract Background This study aimed to develop and compare machine learning (ML) based predictive models for lymph node metastasis (LNM) in early T classification oral squamous cell carcinoma (OSCC). Methods We used data from the Surveillance Epidemiology End Results Database validate LNM patients with T1, T2 OSCC. Using simple clinical histopathological data, we developed six ML algorithms predict LNM. The performance of was compared. areas under receiver operating characteristic curves...

Dental infections and maxillary sinusitis are the main causes of osteomyelitis. Osteomyelitis can occur in all age groups, is more frequently found lower jaw than upper jaw. Systemic conditions that alter patient's resistance to infection including diabetes mellitus, anemia, autoimmune disorders predisposing factors for We report a case uncommon broad osteonecrosis precipitated by uncontrolled type 2 mellitus chronic female patient her seventies with no history bisphosphonate or radiation treatment.

This paper presents an edge extraction based automatic algorithm that is suitable for both indoor and outdoor video surveillance, where the background scene as well its illumination changes frequently. The proposed method focuses especially on achieving robustness through adaptation to in background. We extract pieces of information from images represent these segments efficiently designed classes reference are updated with presence new objects or missing existing input long period....

The impact of the senescence related microenvironment on cancer prognosis and therapeutic response remains poorly understood. In this study, we investigated prognostic significance tumor genes (PSTGs) their potential implications for immunotherapy response. Using Cancer Genome Atlas- head neck squamous cell carcinoma (HNSC) data, identified two subtypes based expression PSTGs, acquired from tumor-associated genes, (TME)-related immune-related using consensus clustering. LASSO, constructed a...

Bisphosphonate-related osteonecrosis of the jaw (BRONJ) occurs mainly in female patients. In males occurrence rate is low, which seems to be related low incidence osteoporosis men. Unfortunately, BRONJ tends ignored general dental clinics male patients with a history treatment. occurred patient due clinician's lack interest patient's history. this case, was on bisphosphonate therapy because orchiectomy, and treatment performed without consideration his medical history, resulting BRONJ. We...

Acute mediastinitis is a fatal infection which occurs related to connective tissue of mediastium, in the thoratic organs. Occurrence due craniocervical very rare, and defined as descending necrotizing mediastinitis.November 8th, 2008, man his early fifties visited ER severe swelling on left neck area dyspnea. Antibiotic were administered immediately, vast amount abscess formation pneumomediastinum adjacent tissues observed via chest computed tomography. With cooperation thoracic...

Background and purpose: Many studies recommend nonsurgical auricular correction during the early postnatal period, when cartilage plasticity is high; however, many patients are not eligible for procedure. This study compared different timings of to investigate benefit after optimal period correction. Methods: In this prospective study, 53 ears from 35 with congenital anomaly were assigned two groups according age at correction: “early-group” within 2 weeks birth “late-group” 8 birth....

Idiopathic bronchiolocentric interstitial pneumonia is one of idiopathic pneumonia, which has a relatively aggressive course and poor prognosis.It characterized by diffuse centrilobular nodules radiologically with mainly inflammation fibrosis associated patchy alveolitis lacking granuloma histologically.This disorder recently classified disease category, to our knowledge, there no case report in Korea.We present pneumonia.A 62-year-old man presented exertional dyspnea 1 month duration.The...
