Role Of The Pediatric Dental Provider In Human Papillomavirus (Hpv) Education, Meredith L. Dugoni

Theses and Dissertations

Purpose: This study investigates knowledge about HPV and examines if pediatric dental providers should include HPV education for guardians of patients 10-18 years.

Methods: Legal guardians of 10-18 year-old patients of the Virginia Commonwealth University Pediatric Dental Clinic were enrolled in this prospective cohort study. Participants completed a baseline survey, were provided HPV education, completed an initial follow-up survey, and then completed a 6-month follow-up survey.

Results: A total of 54 participants completed the baseline and initial follow-up surveys and 17 completed the 6-month follow-up survey. The average number of correct responses was 3.4 of 6 knowledge questions, which significantly …

Evaluation Of Volumetric Change Of Periapical Lesions After Apicoectomy As A Measure Of Postsurgical Healing Utilizing Cone Beam Computed Tomography, Eshwar Arasu

Theses and Dissertations

The aim of this study was to evaluate whether volumetric changes in persistent periapical lesions can be detected in follow-ups six months to five years after apicoectomy using cone-beam computed tomography. Patients with a previous treatment history of apicoectomy and for whom a pre-surgical CBCT scan was taken between November 2010 and December 2015 were invited to participate in the study. A post-surgical CBCT image of the treated tooth was obtained at the recall visit. Volumetric and linear measurements of periapical lesions on initial and postoperative CBCT images were performed using DiThreshGUI software and two calibrated examiners—a board-certified endodontist and …

A Comparative Study Of Intraradicular Enterococcus Faecalis Biofilm Removal With Three Root Canal Treatment Systems: A Scanning Electron Microscopy Evaluation, Cyrous Ardalan

Theses and Dissertations

The objective of this study was to evaluate the biofilm removal efficacy of three root canal treatment systems: ProUltra® PiezoFlow™, traditional needle irrigation, and the GentleWave® system in an ex-vivo benchtop study. Twenty-four extracted maxillary and mandibular molars were selected. Teeth were all instrumented to a master apical file size #25 with 4% taper. Teeth were then randomly divided into four experimental groups and two control groups. The root canals were inoculated with a culture of Enterococcus faecalis and incubated for five weeks to form a biofilm. Each group was then treated with one of the different root canal treatment …

A Comparison Of Treatment Planning Modalities For The Pediatric Dental Patient, Martha M. Holland

Theses and Dissertations

Purpose: To assess the treatment modalities of pediatric dentists for restoring Class II lesions in primary molars.

Methods: A survey of eight cases was emailed to AAPD members, who were asked to choose a stainless steel crown (SSC) or composite resin. Treatment choice was associated with provider type, years in practice, behavior management, lesion detection, and patient age.

Results: Clinically detectable caries restored under general anesthesia were treated more often with a SSC. Faculty and residents chose a SSC at a greater rate. Providers with 10 or more years experience chose a SSC more often.

Conclusions: The scope of treatment …

The Prevalence, Predictive Factors, And Classification Of Intrapulpal Cracks In Maxillary Molars Requiring Endodontic Treatment, Husain Karashi

Theses and Dissertations

Diagnosis and treatment of teeth with longitudinal fractures is challenging. Cracks are usually not visible radiographically; they require a thorough evaluation to aid in diagnosis. Patients may be asymptomatic, demanding the dentist rely on clinical findings to make a diagnosis. Early diagnosis of the presence and extent of a crack is essential for the successful management of a cracked tooth. There is limited information in the literature regarding the prevalence or predictive factors of cracks extending into the pulp chamber of teeth. The purpose of this study was to determine the prevalence of intrapulpal cracks in maxillary molars and to …

Orthodontists' And Parents' Perspective Of Occlusion In Varying Anterior-Posterior Positions: A Comparative Study, David H. Lindsey

Theses and Dissertations

Objective: The purpose was to compare orthodontists’ and parents’ perception of orthodontic treatment outcomes in the anterior-posterior (AP) dimension. Assessment of treatment time and compliance were also investigated.

Material and Methods: Parallel surveys for orthodontists (n=1000) and parents (n=750) displayed occlusions from 3 mm Class III (Cl III:3) to 3 mm Class II. Participants rated occlusal relationships on a 100 mm VAS from least to most acceptable (0-100).

Results: 233 orthodontists (23%) and 243 parents (32%) responded. Orthodontists (mean=93.9, 25.9) and parents (mean=80.7, 40.9) rated Class I (Cl I) occlusion most and Cl III:3 least acceptable. No significant difference was …

Profiling Precursor Lipids For Specialized Pro-Resolution Molecules In Platelet-Rich Fibrin Following Fish Oil And Aspirin Intake, Danielle M. Mccormack

Theses and Dissertations

Background: Current research has demonstrated that aspirin and fish oil (EFA) increase plasma levels of specialized pro-resolution molecules (SPMs). This study investigates their effects on SPM precursor pools in platelet rich fibrin (PRF). Methods: Twenty healthy volunteers were randomly assigned to take aspirin; EFA or aspirin and EFA. Four hours later, SPM precursor levels were quantified using combined Liquid Chromatography tandem mass spectrometry. The differences between the groups: Aspirin (yes or no), EFA (yes or no), were analyzed by ANCOVA, testing for group differences after covarying out the baseline value. Results: There were 4 significant interactions, 1 with an aspirin …

Profiling Precursor Lipids For Specialized Pro-Resolution Molecules In Platelet-Rich Plasma Following Fish Oil And Aspirin Intake, Lisa A. Turner

Theses and Dissertations

Background: Unfavorable outcomes following periodontal surgeries can be attributed to impaired resolution mechanisms likely due to decreased levels of specialized pro-resolution molecules (SPM). The current study investigates if SPM substrate pools in platelet-rich plasma preparations (PRP) can be increased by essential fatty acid (EFA) and / or aspirin supplementation. Methods: Nineteen healthy volunteers were randomly assigned to take i) aspirin; ii) EFA; iii) aspirin and EFA. Four hours after intake, the lipid precursor pools in PRP were quantified using combined Liquid Chromatography tandem mass spectrometry (LC-MS/MS) and the data statistically analyzed using ANCOVA. Results: Of the 77 metabolites screened, only …

The practice of dentistry is physically demanding due to static and dynamic postures sustained daily throughout careers. Previous literature suggests that work-related musculoskeletal disorders (WMSD) are not solely the result of work habits, but also due to the individual, his or her physical makeup, genetics, and …

A Comparison Of Moderate Oral Sedation Drug Regimens For Pediatric Dental Treatment: A Pilot Study, Ojas A. Parikh

Theses and Dissertations

Purpose: Compare moderate oral sedation of pediatric patients using Hydroxyzine and Meperidine with either Diazepam or Midazolam in management of pediatric dental patients.

Methods: Randomized, double-blind, crossover pilot study of patients 3 to 7 years of age requiring two sedation visits. Frankl and Houpt behavior scores recorded at injection time, initiation of treatment and 100% oxygen at end of treatment. Postoperative phone call surveys conducted within eight hours and within 24 hours of discharge. Wilcoxon Signed-Rank tests, Fisher’s Exact Chi-squared test and 0.10 significance level.

Results: 25 subjects completed 35 sedations. Eight participants completed both treatments and demonstrated significantly higher …

Dentistry

Purpose: The aim of the study was to compare between the accuracy of mucosa-supported stereolithographic surgical guide versus conventional surgical stent in implant supported overdenture. Materials and methods: Twelve patients with completely edentulous patients were selected for this study and divided into three groups. Group (A): 8 implants were placed in the mandible using conventional surgical stents during implant insertion. Group (B): 8 implants were placed in the mandible using partially limiting mucosa-supported stereolithographic (SLA) surgical guide during implant insertion. Group (C): 8 implants were placed in the mandible using completely limiting mucosa-supported stereolithographic (SLA) surgical guide during implant insertion. …
