Strategies To Encourage Recall And Prevent Relapse After Full Mouth Rehabilitation Under General Anesthesia In Children, Claire Koukol
Strategies To Encourage Recall And Prevent Relapse After Full Mouth Rehabilitation Under General Anesthesia In Children, Claire Koukol
Capstone Experience
Background: Dental caries are preventable. Dentists utilize many prevention strategies in the office and provide at-home education to families. However, once a child develops Early Childhood Caries (ECC), especially in more severe cases, they may need general anesthesia (GA) to complete treatment. While this is an effective way to achieve full mouth dental rehabilitation (FMDR), this burdens the healthcare systems and families and does not come without risk to the patient. Patients with high caries experience remain at high risk of caries relapse after FMDR under GA, sometimes necessitating additional FMDR under GA. While there has been a significant amount …
Association Of Inflammatory Markers And Growth Factors With Radiographically Assessed Wound Healing Of Extraction Sockets, Sasha Mohammadi
Association Of Inflammatory Markers And Growth Factors With Radiographically Assessed Wound Healing Of Extraction Sockets, Sasha Mohammadi
Theses & Dissertations
The purpose of this prospective cohort pilot study was to investigate the association of the periodontal status and inflammatory markers from the gingival crevicular and wound fluid with the healing outcomes following tooth extraction. The central research hypothesis is that extraction sites and the adjacent teeth that exhibit increased markers of inflammation, or decreased growth factors, at baseline or 2 weeks will be associated with reduced healing outcomes observed radiographically 3 months following surgery. Nine patients at the UNMC College of Dentistry who were seeking care to extract a posterior tooth due to advanced periodontal bone loss, non-restorable caries or …

A Cell Culture Model To Study Tobacco Associated Oral Cancer Progression And Treatment Resistance, Amanda Busch
Theses & Dissertations
Head and Neck Squamous cell carcinoma is the 6th most common cancer in the world. Risk factors for HNSCC include alcohol and tobacco consumption, infection with Human Papilloma Virus, and exposure to environmental toxins. Unlike many other cancers, the incidence of HNSCC is growing, yet the treatment options and outcomes have not been significantly improved for decades. An increased understanding of the molecular mechanisms of these cancers is needed for improvement in early diagnosis, enhanced treatment effectiveness, and cancer prevention. 4-nitroquinoline 1-oxide (4NQO) is a well-tested, tobacco mimicking, carcinogen. 4NQO produces similar histological and chemical changes found in human …

Effect Of Nanofiller Coating And Loading On Facial Elastomer Physical Properties, Rahmi K. Aulia
Effect Of Nanofiller Coating And Loading On Facial Elastomer Physical Properties, Rahmi K. Aulia
Theses & Dissertations
Current materials used for facial prostheses are far from being desirable, and improved properties with “skin-like” feel are needed. This study evaluates property changes induced by sequential additions of uncoated and hydrophobic-coated nano-SiO2 to polydimethylsiloxane (PDMS) and compares them with those measured for conventional submicron SiO2-filled materials. Each filler type was sequentially added to vinyl-terminated PDMS at 0%, 0.5%, 5%, 10%, and 15% by weight. Tensile, tear, Durometer hardness, translucency and viscoelastic properties were evaluated, with hardness and translucency also evaluated following 3000 hours of outdoor weathering. Results demonstrated that 15% coated nano-SiO2-filled PDMS materials …

Sarcoidosis Of The Mandibular Condyle: A Rare Disease That Can Mimic Malignancy, Chad Sloan, Ben Lacrosse, Lei Yu, Alexander Braun, Scott Lauer, Timothy Donovan, John Baker, Jason Untrauer
Graduate Medical Education Research Journal
Sarcoidosis can involve any of the organs, however intraosseous involvement is rare and ranges from 5 to 15%, with lesions of the mandible being even rarer – currently with few known cases reported. Intraosseous lesions involving the mandible have been noted to be asymptomatic or associated with chronic jaw pain. Additionally, mandibular involvement can present as a lytic bone lesion mimicking osseous malignancy. Chronic polyarthritis is commonly associated with the progression of sarcoidosis and intraosseous involvement has been considered a late-stage sequelae. We report a case of biopsy-proven sarcoidosis within the mandibular condyle in an asymptomatic 56-year-old Caucasian female who …

Cpap-Mad Combination Therapy For Cpap Intolerant Patients With Moderate To Severe Osa, Jacob Stadiem
Theses & Dissertations
The treatment of obstructive sleep apnea (OSA) allows for a multidisciplinary approach between dentistry and medicine. Continuous positive airway pressure (CPAP) is the gold standard for OSA treatment, but the non-adherence rates are high. The mandibular advancement device (MAD) has a higher acceptance rate than the CPAP, however the efficacy is much lower in cases of moderate to severe OSA. This thesis attempted to evaluate if there was a change in compliance when a MAD was added as a combination therapy to moderate to severe OSA subjects that were currently non-compliant with their CPAP. In addition, the change in air …
