A Randomized Controlled Trial To Compare The Histomorphometric And Clinical Outcomes Of Soft Tissue Augmentation At The Time Of Lateral Ridge Augmentation Procedures, Kenneth Liu Jan 2021

A Randomized Controlled Trial To Compare The Histomorphometric And Clinical Outcomes Of Soft Tissue Augmentation At The Time Of Lateral Ridge Augmentation Procedures, Kenneth Liu

All ETDs from UAB

Guided bone regeneration (GBR) can be used to augment deficient alveolar ridges in preparation for dental implant placement. Mucogingival deformities can result from the periosteal releasing incision during GBR. This can be addressed by additional soft tissue augmentation procedures to increase the width of keratinized tissue and vertical soft tissue thickness, both of which have demonstrated clinical benefits around implants. The drawbacks of soft tissue augmentation following ridge augmentation include an additional procedure, increased patient morbidity, and less patient acceptance of treatment. In general, soft tissue augmentation can be performed at various time points throughout treatment, but literature on soft …

Evaluation Of Antimicrobial Effect Of Licorice Extrcat Agiasnt Oral Microorganisms, Roshanak Rastegar

All ETDs from UAB

Introduction: The causative factors of dental caries have been studied for many years, however, preventing the formation of dental caries remains an elusive task. Microorganisms have been the focal point of numerous studies as a prime cariogenic factor. Streptococcus mutans and Candida albicans have been frequently co-isolated from dental biofilm in patients with early childhood caries (ECC) and studies have demonstrated the synergistic effects of these two microorganisms in promoting tooth demineralization. Acid and glucan production, which are two virulence factors produced by S. mutans that mediate biofilm formation and tooth decay, have been shown to be promoted during co-colonization …

External Apical Root Resorption In Asian Orthodontic Patients In Alabama, Najd Aswad

All ETDs from UAB

The main goals of orthodontic treatment are to achieve a harmonious dentalocclusion and enhance the patient’s dentofacial appearance. External Apical Root Resorption (EARR) is a side effect of orthodontic treatment1. It results in the permanent loss of tooth structure from the root apex2. EARR is a multifactorial condition which includes patient related and treatment related risk factors. Patient-related factors include genetics, severity of malocclusion, tooth-root morphology, systemic factors, density of alveolar bone, root proximity to cortical bone, previous exposure to trauma, patient age and sex. Orthodontic treatment related risk factors include treatment duration, amount of force and mechanics used, direction …


Midpalatal Suture Maturation Stage Evaluation In Young Adults, Anna Maria Betlej Jan 2021

Midpalatal Suture Maturation Stage Evaluation In Young Adults, Anna Maria Betlej

All ETDs from UAB

Rapid palatal expansion (RPE) is a gold standard treatment for posterior unilateral and bilateral crossbites or limited buccal overjet in patients with constricted maxilla. Midpalatal suture fusion is a limitation for obtaining the skeletal results and avoiding dental side effects. It is generally believed that midpalatal suture interlock increases significantly after the pubertal growth spurt. However, in the literature there are reported cases of successful midpalatal suture split in older adults. Individual cone-beam computed tomography (CBCT) assessment of midpalatal suture maturation was proposed by Angelieri et al. Since RPE treatment approach is commonly used it is important to understand the …
