Effect Of Porcelain Thickness And Translucency On The Final Shade Of Ips E.Max Cad Overlaying A Dark Substrate., Peter F. Alena

Electronic Theses and Dissertations

IPS e.max is a very esthetic lithium disilicate used in dental ceramics. Unfortunately, it can unintentionally change color after cementation with resin cements. The purpose of this study is to better understand how combining thickness and translucency affects the post-cementation shade of IPS e.max CAD overlaying a dark substrate, thereby enabling clinicians to choose more appropriate techniques and materials. IPS e.max CADs (A1 shade) had either a low translucency (LT) or high translucency (HT), and cut with 0.3mm, 0.5mm, and 1.0mm thicknesses. Each sample overlaid a resin cement and dark substrate, a spectrophotometer helped derive the color difference (ΔE*ab), and …

Periodontitis In Patients With Type 2 Diabetes Mellitus, Simran Agarwal, Deepthi Gangaram, Mir Saleem

Biology Faculty Articles

Periodontitis is a chronic, inflammatory disease that is characterized by swollen gums, degradation of jaw structure, and potentially tooth loss. Like Periodontitis, Type 2 Diabetes Mellitus is also highly prevalent and largely multifactorial. Type 2 Diabetes is a condition in which higher than normal blood glucose levels cannot be properly maintained as the body’s normal mechanism of maintaining proper blood glucose levels, the release of insulin from pancreatic islet β-cells, becomes ineffective. The purpose of this literature review is to explore the relationship between the incidences of Periodontitis and Type 2 Diabetes. The risk that Type 2 Diabetes poses for …

Development Of Blended Polymeric Fibers To Alter The Release Of Peptide Targeting Porphyromonas Gingivalis., Sonali Suresh Sapare

Electronic Theses and Dissertations

Periodontitis is a chronic inflammatory disease that infects the tissues of the periodontium. It is estimated that 47.2% or 67.2 million American adults suffer from mild, moderate and severe periodontitis. Globally, 30-50% of the adult population is afflicted with periodontal disease, making it one of the most prevalent infectious diseases in the world. Therapeutics targeting P. gingivalis may be effective to alter periodontitis progression. However, the current treatment modalities that target critical pathogens to maintain host-biofilm homeostasis are limited, urging the development of specifically targeted therapeutics to limit P. gingivalis recolonization of the oral cavity after periodontal treatment and healing. …
