Salivary Mmp-9 In The Detection Of Oral Squamous Cell Carcinoma, Andre Peisker, Gregor F. Raschke, Mina D. Fahmy, Arndt Guentsch, Korosh Roshanghias, Joschka Hennings, Stefan Schultze-Mosgau

School of Dentistry Faculty Research and Publications

Background: Oral squamous cell carcinoma (OSCC) is the most common malignant tumour of the oral cavity. Detection of OSCC is currently based on clinical oral examination combined with histopathological evaluation of a biopsy sample. Direct contact between saliva and the oral cancer makes measurement of salivary metalloproteinase- 9 (MMP-9) an attractive alternative.

Material and Methods: In total, 30 OSCC patients and 30 healthy controls were included in this prospective study. Saliva samples from both groups were collected, centrifuged and supernatant fluid was subjected to ELISA for assessment of MMP-9. The median salivary MMP-9 values with interquartile range (IQR) of OSCC …

School of Dentistry Faculty Research and Publications

The inflammatory process is a coordinated response that protects host after infection or trauma, involving several molecular reactions. Once the inflammation is closely linked to the process of destruction of the temporomandibular joint, this study aims to examine, by immunohistochemistry, the expression of interleukin-6 (IL-6), an important inflammatory marker, in temporomandibular articular discs of patients with anterior disc displacement with (ADDwR) and without reduction (ADDwoR) and its association with osteoarthrosis (OA). Thirty-eight (n = 38) articular discs were divided into two cutoffs: 1) analysis 1: 4 control (acute pathology), 17 ADDwR, 17 ADDwoR; and 2) analysis 2: without OA (n …

A solvent-free microsphere sintering technique was developed to fabricate scaffolds with pore size gradient for tissue engineering applications. Poly(D,L-Lactide) microspheres were fabricated through an emulsification method where TiO₂ nanoparticles were employed both as particulate emulsifier in the preparation procedure and as surface modification agent to improve bioactivity of the scaffolds. A fine-tunable pore size gradient was achieved with a pore volume of 30 ± 2.6%. SEM, EDX, XRD and FTIR analyses all confirmed the formation of bone-like apatite at the 14^th day of immersion in Simulated Body Fluid (SBF) implying the ability of our scaffolds to bond to …

Porous Magnesium-Based Scaffolds For Tissue Engineering, Mostafa Yazdimamaghani, Mehdi Razavi, Daryoosh Vashaee, Keyvan Moharamzadeh, Aldo R. Boccaccini, Lobat Tayebi

School of Dentistry Faculty Research and Publications

Significant amount of research efforts have been dedicated to the development of scaffolds for tissue engineering. Although at present most of the studies are focused on non-load bearing scaffolds, many scaffolds have also been investigated for hard tissue repair. In particular, metallic scaffolds are being studied for hard tissue engineering due to their suitable mechanical properties. Several biocompatible metallic materials such as stainless steels, cobalt alloys, titanium alloys, tantalum, nitinol and magnesium alloys have been commonly employed as implants in orthopedic and dental treatments. They are often used to replace and regenerate the damaged bones or to provide structural support …

While bone grafts and varying reconstructive procedures have been traditionally used for maxillofacial defects, the goal of this review is to provide insight on all materials involved in the progressing utilization of the tissue engineering approach to yield successful treatment outcomes for both hard and soft tissues. In vitro and in vivo studies that have demonstrated the restoration of bone and cartilage tissue with …

Expression Of Interleukin-1 And Temporomandibular Disorder: Contemporary Review Of The Literature, Adam Sorenson, Kyle Hresko, Seth Butcher, Sean Pierce, Vinícius Augusto Tramontina, Rosalia Leonardi, Carla Loreto, Jose A. Bosio, Luis Eduardo Almeida

School of Dentistry Faculty Research and Publications

Objective: Temporomandibular disorders (TMD) are a group of conditions affecting the temporomandibular joint (TMJ), leading to jaw dysfunction, joint and muscle pain, and a decrease in quality of life. A communication network of pro- and anti-inflammatory mediators called cytokines maintains the homeostasis of the TMJ. This review will focus on the Interleukin (IL) family of cytokines, which have been quantified in TMJ synovial fluids in a variety of studies. IL-1α and IL-1β have pro-inflammatory effects, while the endogenous receptor antagonist (IL-1RA) inhibits the pro-inflammatory effects of IL-1.

Methods: A literature search (2006–2016) to identify eligible studies was completed …

School of Dentistry Faculty Research and Publications

In this research, the three dimensional porous scaffolds made of a polycaprolactone (PCL) microsphere/TiO₂ nanotube (TNT) composite was fabricated and evaluated for potential bone substitute applications. We used a microsphere sintering method to produce three dimensional PCL microsphere/TNT composite scaffolds. The mechanical properties of composite scaffolds were regulated by varying parameters, such as sintering time, microsphere diameter range size and PCL/TNT ratio. The obtained results ascertained that the PCL/TNT (0.5 wt%) scaffold sintered at 60 °C for 90 min had the most optimal mechanical properties and an appropriate pore structure for bone tissue engineering applications. The average pore size …

Optimizing Anterior Implant Outcome Immediately After Implant Placement And Grafting By Using Patient’S Extracted Teeth: A Case Report, Soni Prasad, Jay Darryl Banez, Despoina Bompolaki, Yvonne Hart

School of Dentistry Faculty Research and Publications

Optimizing anterior implant outcome using patient’s extracted teeth.

Successful implant treatment in the anterior maxilla is predicated on providing a functional and esthetically acceptable outcome. As well, achieving a predictable ideal emergence profile and soft tissue contour is expected. Placing immediate provisional restorations utilizing the patient’s modified extracted teeth can facilitate initiate facial soft tissue contouring while precluding undue pressure on the surgical site during the early healing phase. This allows for a one stage surgical procedure, fixed provisionalization and ideal tissue contouring.

This clinical report presents the use of a patient’s modified extracted permanent teeth as bonded fixed provisional …

The oral cavity is the first component of the digestive tract, which is delimited by the lips anteriorly and the oropharynx posteriorly. The oral cavity functions as a protective barrier and is an essential component for speech and swallowing, mastication, digestion, and taste sensation.

The oral examination comprises a uniform and consistent inspection of the head and neck and an intraoral evaluation of the hard and soft tissues (see the images below) in conjunction with a thorough medical and dental history. The entire mouth should be inspected regardless of the patient’s chief complaint and reasons for the visit. ^{[1 …}

School of Dentistry Faculty Research and Publications

Diabetes Mellitus (DM) is a group of metabolic diseases characterized by chronic high blood glucose concentrations (hyperglycemia). When it is left untreated or improperly managed, it can lead to acute complications including diabetic ketoacidosis and non-ketotic hyperosmolar coma. In addition, possible long-term complications include impotence, nerve damage, stroke, chronic kidney failure, cardiovascular disease, foot ulcers, and retinopathy. Historically, universal methods to measure glycemic control for the diagnosis of diabetes included fasting plasma glucose level (FPG), 2-h plasma glucose (2HP), and random plasma glucose. However, these measurements did not provide information about glycemic control over a long period of time. To …

Digital Holographic Microscopy Of Phase Separation In Multicomponent Lipid Membranes, Vahideh Farzam Rad, Ali-Reza Moradi, Ahmad Darudi, Lobat Tayebi

School of Dentistry Faculty Research and Publications

Lateral in-homogeneities in lipid compositions cause microdomains formation and change in the physical properties of biological membranes. With the presence of cholesterol and mixed species of lipids, phospholipid membranes segregate into lateral domains of liquid-ordered and liquid-disordered phases. Coupling of two-dimensional intralayer phase separations and interlayer liquid-crystalline ordering in multicomponent membranes has been previously demonstrated. By the use of digital holographic microscopy (DHMicroscopy), we quantitatively analyzed the volumetric dynamical behavior of such membranes. The specimens are lipid mixtures composed of sphingomyelin, cholesterol, and unsaturated phospholipid, 1,2-dioleoyl-sn-glycero-3-phosphocholine. DHMicroscopy in a transmission mode is an effective tool for quantitative visualization of phase …
