All Dugoni School of Dentistry Faculty Articles

A large body of evidence shows the harmful effects of cigarette smoke to oral and systemic health. More recently, a link between smoking and susceptibility to coronavirus disease 2019 (COVID-19) was proposed. COVID-19 is due to infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which uses the receptor ACE2 and the protease TMPRSS2 for entry into host cells, thereby infecting cells of the respiratory tract and the oral cavity. Here, we examined the effects of cigarette smoke on the expression of SARS-CoV-2 receptors and infection in human gingival epithelial cells (GECs).

Bacteriophage Therapy Of Bacterial Infections: The Rediscovered Frontier, Nejat Düzgüneş, Melike Sessevmez, Metin Yildirim

All Dugoni School of Dentistry Faculty Articles

Antibiotic-resistant infections present a serious health concern worldwide. It is estimated that there are 2.8 million antibiotic-resistant infections and 35,000 deaths in the United States every year. Such microorganisms include Acinetobacter, Enterobacterioceae, Pseudomonas, Staphylococcus and Mycobacterium. Alternative treatment methods are, thus, necessary to treat such infections. Bacteriophages are viruses of bacteria. In a lytic infection, the newly formed phage particles lyse the bacterium and continue to infect other bacteria. In the early 20th century, d’Herelle, Bruynoghe and Maisin used bacterium-specific phages to treat bacterial infections. Bacteriophages are being identified, purified and developed as pharmaceutically acceptable macromolecular “drugs,” undergoing strict quality …

The medicinal fungus Ganoderma lucidum is used as a dietary supplement and health tonic, but whether it affects longevity remains unclear. We show here that a water extract of G. lucidum mycelium extends lifespan of the nematode Caenorhabditis elegans. The G. lucidum extract reduces the level of fibrillarin (FIB-1), a nucleolar protein that correlates inversely with longevity in various organisms. Furthermore, G. lucidum treatment increases expression of the autophagosomal protein marker LGG-1, and lifespan extension is abrogated in mutant C. elegans strains that lack atg-18, daf-16, or sir-2.1, indicating that autophagy and stress resistance pathways are required to extend lifespan. …

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 …
