Managing Denture Biofilm Related Diseases, Tingxi Wu, Wenyuan Shi, Zvi G. Loewy, Xuesong He

Touro College of Pharmacy (New York) Publications and Research

The oral cavity harbors more than 700 microbial species and is one of the most complex ecosystems ever described. While the majority of these microbes are considered commensal, some of them are responsible for oral infectious diseases such as dental caries, periodontitis, halitosis and stomatitis. The advancement of modern science has greatly furthered our understanding of oral microbes and their roles in host health and disease. It has also led to the development of new tools for early detection, effective treatment, and prevention of oral microbial infections. This perspective provides a general understanding of oral microbiology, and its clinical relationship …

Adamts-4 And Adamts-5 Expression In Human Temporomandibular Joint Discs With Internal Derangement, Correlates With Degeneration, Rosalia Leonardi, Salvatore Crimi, Luis Eduardo Almeida, Giuseppe Pannone, Giuseppe Musumeci, Sergio Castorina, Mugurel Constantin Rusu, Carla Loreto

School of Dentistry Faculty Research and Publications

Temporomandibular joint (TMJ) internal derangement (ID) is one of the most common form of temporomandibular disorders. There is evidence showing the increased expression of matrix metalloproteinases (MMPs) in the cells from degenerated TMJ disc. ADAMTS are a large family of metalloproteases which are responsible for proteoglycans degradation. The present study aimed to evaluate ADAMTS-4 and ADAMTS-5 immunohistochemical expression in human TMJ discs from patients affected by ID, and to find out if there is any correlation with the degree of histopathological changes. Eighteen temporomandibular displaced disc specimens and sixteen TMJ disc control were used for the present study. Specimens were …

Effect Of Additives On Mineral Trioxide Aggregate Setting Reaction Product Formation, Angela M. Zapf, Sharath C.V. Chedella, David W. Berzins

School of Dentistry Faculty Research and Publications

Introduction

Mineral trioxide aggregate (MTA) sets via hydration of calcium silicates to yield calcium silicate hydrates and calcium hydroxide (Ca[OH]₂). However, a drawback of MTA is its long setting time. Therefore, many additives have been suggested to reduce the setting time. The effect those additives have on setting reaction product formation has been ignored. The objective was to examine the effect additives have on MTA's setting time and setting reaction using differential scanning calorimetry (DSC).

Methods

MTA powder was prepared with distilled water (control), phosphate buffered saline, 5% calcium chloride (CaCl₂), 3% sodium hypochlorite (NaOCl), or …

Immunohistochemical Assessment Of Cytokeratin 17 And Epcam Expression In Different Grades Of Oral Squamous Cell Carcinoma, Safaa El-Baz, Iman Helmy, Mohamed Hosam El Mallahy

Dentistry

Oral squamous cell carcinoma (OSCC), one of the most common malignancies in the head and neck region, is graded based on Broder’s classification into well-differentiated, moderately, and poorly differentiated. Cytokeratin 17 (K17, CK17) is an acid-type I cytokeratin with a low-molecular weight of 48.1 kDa. Epithelial cell adhesion molecule (EpCAM) is a hemophilic Ca2+ independent adhesion molecule. This study used an immunohistochemical technique (IHC) to examine the expression of CK17 and EpCAM in thirty-two specimens of OSCC (comprising 13 well-, 9 moderately, and 10 poorly differentiated cases), and 2 specimens of normal oral mucosa, used as control. It was found …

Exploration Of Materials Used In 3-Dimensional Printing For The Dental Industry, Holly Chang Hayden

Scripps Senior Theses

A limiting factor in the digitization of dental devices is the availability of materials suitable for use in both dentistry and the new digital technologies. As a rapidly growing industry, three-dimensional printing (3DP) has the potential to disrupt traditional manufacturing and prototyping methods. A review of both restorative materials and the current 3DP materials has lead to a focus on fiber- reinforced composites in the exploration for a new 3DP material. In addition, another area worth exploring and investing in would be 3D bioprinting as it opens up the possibility of regenerative dentistry.

The Accuracy Of A Clinician's Assessment Of Insertion Torque At Implant Placement, Britany Fabian Matin

All ETDs from UAB

Background: Primary implant stability contributes to the success of dental implant placement and affects long-term function. Factors that contribute to the primary stability and osseointegration of a dental implant include the quality and quantity of bone present at the site of placement as well as the shape and surface treatment of the implants. There are numerous methods that assist the clinician in determining implant stability during placement and to confirm osseointegration after a period of healing. Their reliability to predict implant success, however, has not been proven. Torque measurements acquired during implant placement have been used as a method for …

Investigation Of Force Decay In Aesthetic, Fibre-Reinforced Composite Orthodontic Archwires, Jacob E. Spendlove, David W. Berzins, Jessica E. Pruszynski, Richard W. Ballard

School of Dentistry Faculty Research and Publications

Background/Objectives: Because polymer-based materials typically exhibit viscoelastic properties, the objective was to determine if commercially available, aesthetic, fibre-reinforced composite archwires maintain continuous forces without undergoing force decay when deflected continuously.

Materials/Methods: Quasi force decay was evaluated by comparing three-point bending profiles of nickel–titanium (NiTi) and fibre-reinforced composite archwires (BioMers) prior to and after 30 days of continuous deflection of either 1 or 2mm. Paired t-tests or non-parametric signed rank tests were used to statistically compare pre- and post-deflection bending forces. A control group consisting of wires not subject to the 30-day constant deflection was tested to check whether the initial …
