Mouthguards help prevent orofacial injuries in many physical activities, commonly to the maxillary incisors. Mouthguards have many different properties which can be idealized. One property involves the amount of impact force the mouthguard can dissipate, commonly referred to as shock absorption. The aim of this study was to improve shock absorption capabilities beyond the protection that a mouthguard made of Ethylene Vinyl Acetate (EVA) can offer. A Nickel-Titanium (NiTi) and/or foam intermediate layer was placed between EVA. Seven configurations were fabricated at 3 different thicknesses. The configurations consisted of an intermediate layer composed of NiTi, foam, or NiTi/foam. The NiTi …
3-D Oropharyngeal Airway Analysis Of Different Antero-Posterior And Vertical Craniofacial Skeletal Patterns In Children And Adolescents, Chi Kim Huynh
3-D Oropharyngeal Airway Analysis Of Different Antero-Posterior And Vertical Craniofacial Skeletal Patterns In Children And Adolescents, Chi Kim Huynh

Sleep apnea disorder has recently emerged as a significant public health issue. While the prevalence of obesity is on the rise among children, it is one of the main risk factors associated with apnea. Upper airway dimensions and morphology seem to be major components of obstructive sleep apnea (OSA) and can be affected by different craniofacial patterns. The purpose of this retrospective, cross-sectional pilot study is to correlate gender, Body Mass Index, risk for OSA, neck circumference, and 3-D oropharyngeal airway dimensions in children and adolescents with different antero-posterior (AP) and vertical craniofacial skeletal patterns. A total of 86 pre-orthodontic …

Lateral cephalometric radiographs have been used for years to help diagnose skeletal and dental patterns in Orthodontics. Within the last decade, these radiographs have caught the interest of the department of Anthropology for the identification of gender within the adult and adolescent population. Numerous publications have been made but failed to identify sexual dimorphism in the pre-adolescent population. 303 lateral cephalograms of pre and post Latino adolescence age ranging from 6.5 to 17.9 years old were obtained from University of Nevada, Las Vegas (UNLV) digital database. 25 variables were identified and plotted with all linear and angular measurements transferred into …
Adult Permanent (Extracted) Teeth As A Source Of Dental Pulp-Derived Mesenchymal Stem Cells (Dpsc): A Pilot Study, Charles Hill
Adult Permanent (Extracted) Teeth As A Source Of Dental Pulp-Derived Mesenchymal Stem Cells (Dpsc): A Pilot Study, Charles Hill
UNLV Theses, Dissertations, Professional Papers, and Capstones
Mesenchymal stem cells (MSC) may be derived from a variety of adult human tissues, including dental pulp from extracted or exfoliated teeth. Evidence suggests differences in both the quality and quantity of the dental pulp-derived mesenchymal stem cells (DPSC) obtained from different sources, such as primary or "baby teeth" and adult, permanent teeth. This study aimed to evaluate the potential to obtain DPSC from intact, vital permanent teeth, and characterize the potential isolates using a randomized selection of active dental patients from the University of Nevada, Las Vegas School of Dental Medicine (UNLVSODM). DPSC were extracted, isolated, cultured and characterized …
Design And Testing Of Novel Mouthguard With Intermediate Nitinol And Foam Layers, Adam Kessler
Design And Testing Of Novel Mouthguard With Intermediate Nitinol And Foam Layers, Adam Kessler
UNLV Theses, Dissertations, Professional Papers, and Capstones
It is the aim of this study to investigate a novel mouthguard design that incorporates the use of a nickel-titanium (Nitinol) layer and thin foam layer in addition to EVA layers. It is thought that the Nitinol layer can distribute the force of an impact and that the thin foam layer may absorb this distributed force better than a solid EVA mouthguard of the same thickness. Rectangular, flat coupons representative of several mouthguard configurations were constructed for testing using an instrumented drop-weight impact tower. The coupon configurations include a control made of laminated EVA, a group of laminated EVA and …
