Investigate The Role Of Tgfβ3 In Regulating Irf6 And Δnp63 In Periderm Desquamation, Nam Ha

Theses & Dissertations

Introduction: Failure in palatal fusion during palate development results in cleft palate, one of the most common birth defects in the US. During the final phases of palatogenesis, the palatal periderm (a protective cell layer that prevents premature fusion and adhesion with oral epithelium) must be removed, also known as desquamation. This process is a prerequisite for establishing the midline seam in the fused palate. Previous studies have shown that transforming growth factor-β3 (TGFβ3) plays an irreplaceable role in palate development in mice. Our previously published mechanistic models outline the role of TGFβ3 and its downstream signaling cascade involving proteins …

Strategies To Encourage Recall And Prevent Relapse After Full Mouth Rehabilitation Under General Anesthesia In Children, Claire Koukol

Capstone Experience: Master of Public Health

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 …

Nutrition Needs Assessment For A Produce Prescription Program In The Pediatric Dental Setting, Zachary Houser

Capstone Experience: Master of Public Health

More than half of young people in the U.S. aged 2-19 have a poor-quality diet, including low fruit and vegetable (FV) intake (Liu et al., 2020). Poor nutrition increases health risks, including chronic diseases such as dental caries and obesity, low-income households experience higher rates of poor nutrition and subsequent health burdens (AAPD, 2022b). Produce prescriptions (PPR) are a type of financial incentive program that can improve FV intake among low-income populations (Ridberg et al., 2019).

Impact Of Financial And Demographic Factors On Severity Of Treatment Procedure, Vanessa Gunderson

Theses/Capstones/Creative Projects

Indirect pulp caps (IPCs) and pulpotomies are forms of vital pulp therapy. These procedures are performed on young patients who have deep cavities due to bacterial biofilm damage; however, the two are performed and utilized differently. The less severe of the two procedures is an IPC. This is when decayed dentin is covered with biocompatible material to avoid pulp exposure. The more severe procedure, the pulpotomy, is when the inflamed coronal pulp tissue is removed either partially or fully to save any remaining pulp tissue. In this study, all IPCs and pulpotomies performed by Dr. Ben Reimer throughout ~4.5-years of …
