ABSTRACT The purpose of this study was to analyze the microstrains of compact and trabecular bone caused by loading of different miniscrews at different healing times, and to compare these results to the limits of bone stability maintenance based on the Frost Mechanostat Theory. Materials and Methods: Theoretical calculations of microstrains of bone surrounding 10 different miniscrews were done. These miniscrews were considered under loading forces of 500 gm., and the microstains of both trabecular and compact bone were calculated separately when the thickness of the compact bone was at 1mm or 2mm. The microstrains were calculated at 4 different …

Objective: The purpose of this study was to evaluate the maxillary central incisor position changes after orthodontic treatment in Class I, II and III malocclusions. Material and Methods: This retrospective cohort study evaluated nighty non extraction orthodontic Class I, II and III cases which were collected randomly from the Orthodontic clinic at the University of Alabama at Birmingham and the Institutional Review Board of the University of Alabama at Birmingham approved the study. All the chosen cases were treated with fixed appliances and according to the standards of American Board of Orthodontics. All the lateral cephalo-metric radiographs were taken using …
Three-Dimensional Age-Related Changes Of The Adult Face; African American Female Population, Christina Theresa Sutherland
Three-Dimensional Age-Related Changes Of The Adult Face; African American Female Population, Christina Theresa Sutherland
All ETDs from UAB
Objectives: Treatment of older adults is one of the fastest growing areas in orthodontic practice. The objectives of this study are to: 1. Investigate the aging of the female African American face using three-dimensional surface imaging to understand how the soft tissue of the face matures in relation to the teeth and 2.) Compare the effects of aging on African American female faces to aging of Caucasian female faces. Methods: This is a cross-sectional study of 100 African American females with balanced faces. Five age groups (in years) were included: [20-30], [31-40], [41-50], [51-60], [61-70]. Three-dimensional (3D) surface images of …
Consequences Of Trps1 Deficiency On Dentinogenesis, Morgan Goss
Consequences Of Trps1 Deficiency On Dentinogenesis, Morgan Goss
All ETDs from UAB
Dentinogenesis is a complex process of dentin formation. It involves differentiation of odontoblasts, the cells that make dentin, and the formation of a unique extracellular matrix, known as dentin. Dentin is ultimately produced through the interaction of collagen fibers, non-collagenous proteins and hydroxyapatite (HA) crystals. Odontoblasts are cranial neural crest (CNC) ectomesenchymal derived cells. Trps1 is a novel transcription factor believed to play an important role in both tooth formation and the mineralization process. TRPS1 gene mutations are known to result in dental and skeletal abnormalities manifested in humans as tricho-rhino-phalangeal syndrome (TRPS) and Ambras syndrome. Trps1 expression varies throughout …
A Prospective Randomized Clinical Trial To Assess The Performance Of Microtextured Dental Implants With Or Without A Machined Collar- 1 Year Results, Elizabeth Felts Randall
A Prospective Randomized Clinical Trial To Assess The Performance Of Microtextured Dental Implants With Or Without A Machined Collar- 1 Year Results, Elizabeth Felts Randall
All ETDs from UAB
Aim: To assess the performance of microtextured dental implants with or without a machined collar at one year after placement. Material and Methods: Fifty-eight patients received dental implant therapy to restore missing teeth in one area of the maxilla or man-dible at the UAB Department of Graduate Periodontology. Residents in the program placed microtextured implants with a microtextured collar with microgrooves (test group) and microtextured implants with a machined collar (control group). Sites were randomized to the test group or control group. Study visit protocol was followed and implants were restored by off-site dentists. Sixty-nine (69) implants were assessed at …

The Accuracy Of A Clinician's Assessment Of Insertion Torque At Implant Placement, Britany Fabian Matin
All ETDs from UAB
Background: Primary implant stability contributes to the success of dental implant placement and affects long-term function. Factors that contribute to the primary stability and osseointegration of a dental implant include the quality and quantity of bone present at the site of placement as well as the shape and surface treatment of the implants. There are numerous methods that assist the clinician in determining implant stability during placement and to confirm osseointegration after a period of healing. Their reliability to predict implant success, however, has not been proven. Torque measurements acquired during implant placement have been used as a method for …
Comparison Of Three Fluoride Dentifrice Products In The Prevention Of White Spot Lesions In Orthodontic Treatment, Anna B. Palombini
Comparison Of Three Fluoride Dentifrice Products In The Prevention Of White Spot Lesions In Orthodontic Treatment, Anna B. Palombini

Introduction:. During the course of orthodontic treatment, enamel decalcification is a common problem. Demineralized enamel, the precursor to caries formation, can be attributed to fixed orthodontic appliances and prolonged exposure to bacterial plaque. Progression to clinically detectable white spot lesions may occur as early as one month following the placement of orthodontic appliances. Such problems have influenced clinicians to search for a solution. Because fluoride treatment immediately upon debonding is not advocated, clinicians have proposed fluoride treatment and fluoride-releasing materials at the commencement of the therapy. The two new anti-cavity toothpastes, ClinproTM 5000 with 1.1% Sodium Fluoride and ClinproTM Tooth …
