Prevalence And Factors Of Sibling-Recurrent Dental Treatment Under General Anesthesia, Brandy N. Edmonds
Prevalence And Factors Of Sibling-Recurrent Dental Treatment Under General Anesthesia, Brandy N. Edmonds
Theses and Dissertations
Objective/Aims: Assess the prevalence of sibling recurrent dental general anesthesia (DGA) at VCU Pediatric Dentistry. Assess factors that contribute to sibling recurrent dental general anesthesia. Methods: The guardian of patients with siblings were provided a questionnaire to assess the prevalence and factors associated with recurrent DGA. Results: A total of 40 families with a child presenting for GA and at least one sibling were included in the study. Of these, 45% had sibling-recurrent GA treatment (20% in one sibling; 25% in 2 or more siblings). Additionally, 13% of the children currently presenting for GA had already been treated under GA, …

COMPARISON OF HIRING STRATEGIES OF ORTHODONTIC PRIVATE PRACTITIONERS
By Steven C. Petritz, D.D.S.
A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Dentistry at Virginia Commonwealth University
Virginia Commonwealth University, 2018
Thesis Director: Bhavna Shroff, D.D.S., M.Dent.Sc., M.P.A.
Virginia Commonwealth University Department of Orthodontics Program Director
Purpose: Evaluate factors that influence hiring outcomes of clinical and non-clinical staff in orthodontic private practices.
Methods: Orthodontists (n=1968) were surveyed regarding their hiring methods and outcomes. Responses were summarized using descriptive statistics. Chi-square tests were used to compare between hiring strategies and outcomes. …

Introduction: Despite recent advances in three-dimensional (3D) printing, little information is available on 3D printed retainers
Methods: Three reference models were used to fabricate traditional vacuum formed, commercially-available vacuum formed, and 3D printed …
Change In Working Length At Different Stages Of Instrumentation As A Function Of Canal Curvature, Mei Tang
Change In Working Length At Different Stages Of Instrumentation As A Function Of Canal Curvature, Mei Tang
Theses and Dissertations
The aim of this study was to determine the change in working length (∆WL) before and after coronal flaring and after complete rotary instrumentation as a function of canal curvature. One mesiobuccal or mesiolingual canal from each of 43 extracted molars had coronal standardization and access performed. Once the access was completed, canal preparation was accomplished using Gates Glidden drills for coronal flaring and EndoSequence files for rotary instrumentation. WLs were obtained at 3 time points: pre-instrumentation (unflared), mid-instrumentation (flared) and post-instrumentation (concluded). Measurements were made via direct visualization (DV) and the CanalPro apex locator (EM) in triplicate by a …
The Effect Of Instrumentation Taper On Dentin Conservation, Megan E. Green
The Effect Of Instrumentation Taper On Dentin Conservation, Megan E. Green
Theses and Dissertations
Introduction: The aim of this in vitro study was two part. The first being to assess and compare the amount of dentin removed by an instrument with a taper of 0.04 versus an instrument with a taper of 0.06 using the Edge Evolve® file system at different increments within the canal system. Secondly, this study evaluated whether instrumentation with either taper resulted in a remaining dentin thickness (RDT) of less than 0.3mm. If this RDT was imposed upon, fracture resistance was compromised. Both pre and post instrumentation measurements were taken of samples instrumented with the 0.04 and 0.06 tapered files. …
Observations Of Trends And Successes Of Revascularization Therapy At Virginia Commonwealth University: A Retrospective Study, Richard W. Sedwick
Observations Of Trends And Successes Of Revascularization Therapy At Virginia Commonwealth University: A Retrospective Study, Richard W. Sedwick
Theses and Dissertations
The aim of this study was to determine the trends in protocol, success rates, and consistency in follow up of revascularization procedures in a controlled environment. Patients of the Virginia Commonwealth University School of Dentistry were identified who were offered revascularization therapy as a treatment option on immature permanent teeth from January 1, 2010 to May 31, 2017. A total of 77 patients and 78 teeth were evaluated for revascularization therapy. For patients accepting treatment, records were reviewed for outcome assessment and consistency of follow up. A total of 30 patients (31 teeth) were treated following revascularization protocols, with only …

RNA-Binding Proteins (RBPs) play important regulatory roles in countless cellular processes. Often via the induction of a structural change in RNA’s secondary structure, RBPs are known to modulate protein expression through post-transcriptional regulation. In Escherichia coli, such RBPs have …
