Objective Physiological Measures Of Lingual And Jaw Function In Healthy Individuals And Individuals With Dysphagia Due To Neurodegenerative Diseases, Megan E. Cuellar, Elizabeth Oommen

Faculty Research, Scholarly, and Creative Activity

Swallowing is a neuromuscular process that involves a complex sequence of sensorimotor events, which are executed to efficiently and safely transport food and liquid from the mouth to the stomach. Safe oropharyngeal swallowing involves the activation, modulation, and coordination of oral, pharyngeal, laryngeal, and esophageal structures and musculature. Impaired or atypical patterns of swallowing are considered characteristic of a swallowing disorder, otherwise referred to as dysphagia, and affect the performance of all stages, i.e., oral preparatory, oral transit, pharyngeal, and esophageal. Lingual and jaw musculature play critical roles in mediating swallowing function, particularly during the oral preparatory and oral transit …

Oral Health Science Faculty Publications

BACKGROUND: The purpose of this study was to identify pretreatment factors associated with the stability of early class III treatment, since most orthodontists start the treatment with their uncertain hypotheses and/or predictions. Subjects consisted of 75 patients with a class III skeletal relationship (ANB < 2° and overjet < 0 mm) who had been consecutively treated with rapid maxillary expansion and facemask and followed until their second phase treatment. The patients were divided into two groups according to whether they showed relapse in follow-up. The stable group maintained their positive overjet (n = 55), and the unstable group experienced relapse with a zero or negative overjet (n = 20). Two general, three dental, and 13 cephalometric pretreatment factors were investigated to determine which factors were associated with stability.

RESULTS: Sex, pretreatment age, and anteroposterior functional shift, which were hypothesized as associated factors, were not related to …

Comparing Orthodontic Debonding Aerosol Production With Various High-Volume Evacuation Systems, Eric Moe

Master's Theses (2009 -)

Objective: The COVID-19 pandemic has placed a new emphasis on defining aerosol generating procedures and evaluating ways to reduce those aerosols. Both biocontaminants and particulate matter can potentially be transmitted with dental aerosols with negative health effects associated with each, especially aerosols with particulate matter of 2.5 micrometers or less (PM2.5). This study aims to evaluate the PM2.5 aerosol production from orthodontic debonding with a high-speed, air-driven handpiece without water coolant and assess the effectiveness of traditional four-handed high-volume evacuation (HVE) and two commercially available hands-free high-volume evacuation (HFHVE) systems. Methods: Orthodontic debonding was simulated using a dental manikin and …

Bending And Phase Transformation Properties Of A Force Gradient Nickel-Titanium Orthodontic Wire, Brinda Shah

Master's Theses (2009 -)

Objective: Conventional nickel-titanium (NiTi) archwires have widespread application in orthodontics due to their unique properties and ability to move teeth with light, continuous forces, but a shortcoming is that they apply near-uniform force along anterior and posterior teeth. Since the force needed to effectively move teeth is a function of the root surface area and bony support, these archwires cause single-rooted teeth to move more than the multi-rooted molars. With the advent of laser-engineered force gradient NiTi orthodontic archwires, individual forces may be applied to different segments or individual teeth of the arch to maximize tooth movement. The aim of …

Mechanism Of Mechanical Vibration In Enhancing Orthodontic Retention, Brent A. Ito

Master's Theses (2009 -)

Introduction: Low-magnitude, high-frequency (LMHF) mechanical vibration is proven to be anabolic and can increase alveolar bone mass. The objectives of this study were to generate an orthodontic retention cell culture model and investigate the effects of LMHF mechanical vibration on human periodontal ligament fibroblast (HPLF) cells after orthodontic loading (retention) in vitro. Materials and Methods: HPLF cells were seeded at a density of 4x105/well in 6-well Flexcell culture plates (Day 0). On day 3, the cells were mechanically stretched (15% surface extension) for 1 hour to mimic orthodontic loading/tension in vitro. On day 5, the cells were randomly assigned to …

Taiwanese Journal of Orthodontics

To achieve a satisfactory outcome for transposed impacted teeth, the esthetic assessment and functional rehabilitation should be considered from both the orthodontic and periodontic perspective. In this case, a stepwise approach was used for both surgical uncovering and orthodontic treatment to manage the soft and hard tissue of transposed high canine. The case involved a girl aged 11 years and 7 months with bilateral high impacted canine–lateral incisor transposition. The impacted canines were first uncovered with the closed eruption technique and then moved horizontally to a normal sequence in the arch. Apically repositioned flap surgery was then performed, and the …

Management Of Unilateral Maxillary Canine Impaction, Maureen Antolis, Krisnawati E. Tarman

Taiwanese Journal of Orthodontics

Maxillary canine is an essential part of teeth for smile esthetic and function. Orthodontic treatment for patient with impacted maxillary canine is considered to be more complex and require good biomechanical control during traction. This case report describes an orthodontic treatment of a 17-year old female patient with unilateral maxillary canine impaction on the left side. Orthodontic traction was used to guide the canine into normal occlusion. The orthodontic treatment had been completed within 19 months and successfully obtained favourable esthetic and stable occlusion.
