Effects Of Unilateral Extraction Treatment On Arch Symmetry And Occlusion, Theodore William Struhs
Theses and Dissertations
Occlusal asymmetries are common in orthodontic patients. A treatment option for correcting moderate asymmetries is asymmetric extractions. This study evaluated post-treatment dental arch symmetry in patients treated with unilateral premolar extractions. Post-treatment casts of 60 patients were divided into four treatment groups based on the history of occlusal asymmetry and the treatment plan. DesignCAD3000 software (Upperspace Corporation, Pryor, OK) was used to evaluate asymmetrically treated arches for symmetry. The four treatment groups were compared to identify differences in arch asymmetry based on treatment. The lateral incisor and canine were found to be more palatal on the extraction side in patients …

A Radiographic Analysis Of Variance In Lower Incisor Enamel Thickness, Nathan E. Hall
Theses and Dissertations
The purpose of this study was to help predict the enamel thickness of mandibular incisors. At least two direct digital periapical radiographs were made for each of the 80 subjects. Radiographs were scaled to control for magnification errors using dental study models and computer software. Mesiodistal incisor width and mesial and distal enamel thicknesses were measured. Lateral incisors were determined to be wider than central incisors and distal enamel thicknesses were larger than mesial enamel thicknesses on average. The African American group demonstrated wider incisors and enamel thicknesses than the Caucasian group on average. Enamel thickness positively correlated with tooth …

Overbite Correction And Smile Esthetics, Sherif Nabil Elhady
Theses and Dissertations
The purpose of this prospective clinical study was to investigate differences in outcomes from two common treatment modalities used to reduce deep overbite: maxillary incisor intrusion using an intrusion arch and posterior tooth eruption using an anterior bite plate and to assess their influence on smile esthetics. Pre-treatment and post-overbite correction records were gathered from 40 patients with deep overbite malocclusions at the Virginia Commonwealth University orthodontic clinic. Intrusion arch patients displayed significant reductions in maxillary incisor display accompanying documented incisor intrusion. Bite plate patients showed significant lower incisor intrusion and increases in the mandibular plane angle. When compared to …
Prevalence Of Pulpal And/Or Periradicular Disease In The Vcu School Of Dentistry Screening Patient Population, Ellen Rives Oertel
Prevalence Of Pulpal And/Or Periradicular Disease In The Vcu School Of Dentistry Screening Patient Population, Ellen Rives Oertel
Theses and Dissertations
The purpose of this study was to determine the prevalence and demographic predictors of pulpal and/or periradicular disease in an urban population. A total of 210 subjects were recruited from a population of patients that were screened for acceptance to the dental school clinics. The diagnosis of pulpal and/or periradicular disease was made using the following data: radiographic interpretation, patient's history of previous pain and chief complaint, and objective pulpal testing. Objective pulpal testing included percussion, palpation, electric pulp test, and cold. The unit of observation was the individual, not the tooth.
