Eighteen anthropometric indices reflecting the perioral morphology and its integration in the vertical facial harmony were investigated. Results: The intercanthal – mouth width index …

Thermal Properties Of Copper Nickel-Titanium Orthodontic Archwires, Joshua Gilbert

Master's Theses (2009 -)

Introduction: Copper Nickel-Titanium (CuNiTi) is a relatively new composition of Nickel-Titanium (NiTi) archwires that was originally patented in 1991 as part of the Ormco line of wires. The patent has now recently expired and many other orthodontic companies are making their own CuNiTi wires. Advertisement claims have focused on the laboratory benefits of adding Copper (Cu) to the NiTi, however few independent laboratory testings have been conducted on these new wires to verify claims. The purpose of this study was to conduct thermal analysis of CuNiTi for all currently available wires in two Austenite Finish (Af) variants and two commonly …

Mechanical Properties Of Copper-Nickel-Titanium Archwires, Margaret Amelia Rosen

Master's Theses (2009 -)

Introduction: The initial phase of orthodontic therapy relies on flexible wires, usually composed of a nickel-titanium alloy, to apply a substantially constant load during tooth movement. Copper has been added to nickel-titanium archwires, resulting in an alloy with potential clinical advantages such as a lower stress hysteresis. Many orthodontic companies claim that their copper-nickel-titanium manufacturing process allows for the production of more consistent transition temperatures in the wires, allowing the orthodontist to customize treatment to various patients based on the force level needed. There are currently many manufacturers of these wires, creating a wide range of copper-nickel-titanium archwires from which …

The smile of the photo was manipulated to represent one of four conditions: no orthodontic appliance, a metal orthodontic appliance, a ceramic orthodontic appliance, or a clear aligner. Subjects then rated the employee on three continuous Likert scales. Ratings of job performance, intelligence, and attractiveness …

The Effects Of Mechanical Vibration On Human Chondrocytes In Vitro, Bradley J. Gauthier

Master's Theses (2009 -)

Introduction: Inflammation is the biological basis of temporomandibular joint disorders (TMD), when severe it can lead to osteoarthritis. One of the physical therapies used to manage this condition is mechanical vibration, as has been used in medicine for many years as a non-pharmacological therapy. Recently an FDA approved dental device called AcceleDent has been introduced to increase the rate of tooth movement and decrease pain. As the device-generated vibration transmits to the TMJ, it is important for us to investigate whether mechanical vibration influences TMJ on its biologic basis – chondrocytes under normal and inflammatory conditions. Materials and Methods: Human …

The Effect Of Mechanical Vibration On Human Pdl Cell Differentiation And Response To Inflammation, Megan Desroches

Master's Theses (2009 -)

Low magnitude mechanical vibration is a therapeutic adjunct being investigated to alter bone remodeling and inflammation in areas such as osteoporosis, bone fracture healing, and muscle soreness after exercise. In orthodontics a device named AcceleDent has been marketed that claims to increase the rate of tooth movement and decrease pain. However evidence for these claims is lacking. In this study we looked at two potential cellular mechanisms for these claims: periodontal ligament (PDL) cell differentiation and inflammation under an orthodontic model of strain (IL-1β). Increased PDL cell differentiation into osteogenic cells could be an avenue of increasing orthodontic tooth movement. …

Phylotoast: Bioinformatics Tools For Species-Level Analysis And Visualization Of Complex Microbial Datasets, Shareef M. Dabdoub, Megan L. Fellows, Akshay D. Paropkari, Matthew R. Mason, Sarandeep S. Huja, Alexandra A. Tsigarida, Purnima S. Kumar

Oral Health Science Faculty Publications

The 16S rRNA gene is widely used for taxonomic profiling of microbial ecosystems; and recent advances in sequencing chemistry have allowed extremely large numbers of sequences to be generated from minimal amounts of biological samples. Analysis speed and resolution of data to species-level taxa are two important factors in large-scale explorations of complex microbiomes using 16S sequencing. We present here new software, Phylogenetic Tools for Analysis of Species-level Taxa (PhyloToAST), that completely integrates with the QIIME pipeline to improve analysis speed, reduce primer bias (requiring two sequencing primers), enhance species-level analysis, and add new visualization tools. The code …

Alternative Functions For The Multifarious Inflammasome, J. Martel, H. C. Lai, Y. F. Ko, J. D. Young, David M. Ojcius

All Dugoni School of Dentistry Faculty Articles

The inflammasome has been mainly studied in innate immune cells in which it senses microbes and cellular damage, and induces secretion of pro-inflammatory cytokines. This process induces an inflammatory response that is critical for the resolution of infections and repair of tissue damage following injury. Recent studies indicate that inflammasome complex formation also participates in many other cellular and physiological processes beyond modulation of inflammation, such as autophagy, metabolism, eicosanoids production, and phagosome maturation.

Influence Of Low Temperature Degradation On Microstructural Integrity Of Zirconia Dental Implants, Mona Monzavi Rahimi

Loma Linda University Electronic Theses, Dissertations & Projects

Zirconia dental implants have become more popular in the field of implant dentistry. However, concerns have been raised regarding low temperature degradation and its influence on phase stability and micro-structural integrity in terms of increased micro-crack formation. In the case of dental implants, this could possibly result in delamination and interference with bone to implant contact and eventually lead to loss of integration and failure. Nevertheless, no study has reported the effects on commercially available Zirconia dental implants. The primary aims of this study was to determine if there is a correlation between ageing duration and 1) depth of tetragonal-monoclinic …
