Passive activation of endodontic irrigants provides improved canal disinfection, smear layer removal, and better subsequent sealing. Although evidence suggests that passive activating endodontic devices increase the effectiveness of irrigation, no study exists to quantitatively compare and validate vibrational characteristics and cavitation produced by different ultrasonic endodontic devices. The current study aims to compare the efficiency of various commercially available ultrasonic endodontic activating devices (i.e., EndoUltra™, EndoChuck, Irrisafe™, and PiezoFlow®). The passive endodontic activating devices were characterized in terms of tip displacement and cavitation performance using scanning laser vibrometry (SLV) and sonochemical analysis, respectively. The obtained results showed that …

A Case Study Of Barriers To Dental Care In Nebraska, Kaitlin Buhler

Honors Program: Senior Projects (Public)

An important aspect of overall health is access to dental care, which is, unfortunately, oftentimes difficult to obtain. This study used data collected from a case study of three registered dentists in Nebraska to investigate the barriers to dental care, and identified the lack of dental insurance, limited access to free or reduced-price dental care, and dental anxiety as perceived barriers to dental care. Factors that did not seem to have an impact were language or ethnicity differences between patients and workers, distance to travel, comfortability with receiving free or reduced-price dental care, knowledge of how often to visit the …

Improving bone regeneration is one of the most pressing problems facing bone tissue engineering (BTE) which can be tackled by incorporating different biomaterials into the fabrication of the scaffolds. The present study aims to apply the 3D-printing and freeze-drying methods to design an ideal scaffold for improving the osteogenic capacity of Dental pulp stem cells (DPSCs). To achieve this purpose, hybrid constructs consisted of 3D-printed Beta-tricalcium phosphate (β-TCP)-based scaffolds filled with freeze-dried gelatin/reduced graphene oxide-Magnesium-Arginine (GRMA) matrix were fabricated through a novel green method. The effect of different concentrations of Reduced graphene oxide-Magnesium-Arginine (RMA) (0, 0.25% and 0.75%wt) on the …

Structure, Wettability, Corrosion And Biocompatibility Of Nitinol Treated By Alkaline Hydrothermal And Hydrophobic Functionalization For Cardiovascular Applications, S. Rahimipour, E. Salahinejad, E. Sharifi, H. Nosrati, Lobat Tayebi

School of Dentistry Faculty Research and Publications

The main objective of this study is to hydrophobize nitinol (Ni-Ti alloy) for cardiovascular applications. For this purpose, medical nitinol samples were subjected to sodium hydroxide hydrothermal treatments at various temperatures, followed by hexadecyltrimethoxysilane (HDTMS) functionalization. Then, the structure, wettability, corrosion, cytocompatibility and cell adhesion of the prepared samples were evaluated. According to the results, porous blade-shaped layers of sodium titanate were formed on the substrate surface as a result of the alkaline treatment. These nano-rough features offered considerable hydrophobicity after HDTMS processing, where a maximum water contact angle of about 140° was obtained for the sample treated at 120 …

An important subgroup within the porphyrazine (Pz) family constitutes seco-porphyrazines, in the chemical structure of which one pyrrole unit is opened in the oxidative process. So far, there are only limited data on N-seco- and C-seco-Pzs. Here, the synthesis of a novel member of the Pzs seco-family, represented by an S-seco-tribenzoporphyrazine analogue, 22,23-bis(4-(3,5-dibutoxycarbonylphenoxy)butylsulfanyl)tribenzo[b,g,l]-22,23-dioxo-22,23-seco-porphyrazinato magnesium(II), is reported, with moderate 34% yield. The new derivative was characterized using NMR spectroscopy, UV–Vis spectroscopy, and mass spectrometry. In the photochemical study performed following the indirect chemical method with 1,3-diphenylisobenzofuran, S-seco-Pz revealed a high singlet oxygen quantum yield of 0.27 in DMF. Potential photocytotoxicity of …

Synthesis And Characterization Of Hemocompatible Antibiotic Nanoparticles, Elvin Muhindo Walemba

Loma Linda University Electronic Theses, Dissertations & Projects

Porphyromonas gingivalis is a causative agent of periodontal disease and a risk factor for cardiovascular disease. Novel treatment of periodontal disease using nanomaterials can supplement or replace the use of antibiotics and mechanical debridement. Nanomaterials can be optimized for effectiveness and specificity and minimum toxicity. Synthesized Ag nanoparticles stabilized in Pluronic F127 were used to produce bimetallic core/shell Ag/Au nanoparticles with optimized Ag+ release and reduced toxicity. We tested the F127-stabilized nanoparticles for their antimicrobial activity and hemocompatibility in planktonic bacteria and citrated whole blood, respectively. Both Ag and Ag/Au bimetallic nanoparticles inhibited P. gingivalis W83 growth. We then evaluated …
