To evaluate structural profiles and mechanical behaviour of WaveOne Gold (WOG), Twisted File Adaptive (TFA) and XP-endo shaper (XPS) instruments after root canal preparation. Standardized in vitro shaping was performed in presence of 5.25% sodium hypochlorite. File morphology was analyzed using scanning electron microscopy; X-ray diffraction analysis was performed before and after use along with Raman spectroscopy. Nanoindentation was carried out to characterize surface topography. Ni2+ release was measured at 1, 3, 5 and 7 days. X-ray photoelectron spectroscopy (XPS) analysis was done before and after use. After allocating scan line shifts like in WOG, mechanical deformation was shown ...

We examined the involvement of the P2 × 7 receptor and the canonical and noncanonical inflammasomes in the control of single-species or dual-species infection by the periodontal bacteria Porphyromonas gingivalis and Fusobacterium nucleatum in cells and mice. Stimulation of the P2 × 7 receptor leads to activation of the canonical NLRP3 inflammasome and activation of caspase-1, which leads to cleavage of pro-IL-1β to IL-1β, a key cytokine in the host inflammatory response in periodontal disease. The non-canonical inflammasome pathway involves caspase-11. Thus, wildtype (WT), P2 × 7−/−, caspase-11−/− and caspase-1/11−/− mice were co-infected with both bacterial species. In parallel, bone marrow-derived macrophages ...


Online Learning During Covid-19 Produced Equivalent Or Better Student Course Performance As Compared With Pre-Pandemic: Empirical Evidence From A School-Wide Comparative Study, Meixun S. Zheng, Daniel Bender, Cindy Lyon 2021 University of the Pacific

Online Learning During Covid-19 Produced Equivalent Or Better Student Course Performance As Compared With Pre-Pandemic: Empirical Evidence From A School-Wide Comparative Study, Meixun S. Zheng, Daniel Bender, Cindy Lyon

All Dugoni School of Dentistry Faculty Articles

Background: The COVID-19 pandemic forced dental schools to close their campuses and move didactic instruction online. The abrupt transition to online learning, however, has raised several issues that have not been resolved. While several studies have investigated dental students’ attitude towards online learning during the pandemic, mixed results have been reported. Additionally, little research has been conducted to identify and understand factors, especially pedagogical factors, that impacted students’ acceptance of online learning during campus closure. Furthermore, how online learning during the pandemic impacted students’ learning performance has not been empirically investigated. In March 2020, the dental school studied here moved ...


Stress And Anxiety Experience Of Dental Hygiene Students, Kristen Ford 2021 East Tennessee State University

Stress And Anxiety Experience Of Dental Hygiene Students, Kristen Ford

Electronic Theses and Dissertations

The ETSU dental hygiene program is very competitive and rigorous for those admitted. Student dental hygienists may experience higher levels of anxiety and more stressors while completing their course work and clinical hours than they have previously experienced in general education and prerequisite courses. These increased number of stressors and higher levels of anxiety may have negative impacts on students’ academic performance and success in clinical learning environments. A better understanding of the actual need for a stress reduction and anxiety management curriculum will facilitate creating and implementing this type of curriculum. A total of 44 current ETSU dental hygiene ...


The U.S. Should Expand Access To Dental Care For Older Adults, Madonna Harrington Meyer, Sarah Reilly, Julia Finan 2021 Syracuse University

The U.S. Should Expand Access To Dental Care For Older Adults, Madonna Harrington Meyer, Sarah Reilly, Julia Finan

Lerner Center for Public Health Promotion: Population Health Research Brief Series

Older adult Medicare recipients face high out-of-pocket dental expenses due to a lack of appropriate dental care coverage. Older adults with lower socioeconomic status tend to have worse oral health, less dental insurance coverage, greater difficulties finding a dentist, and low-quality care. This brief details the experiences socioeconomically disadvantaged older adults face in obtaining appropriate and affordable dental care and calls on Congress to include preventative and restorative dental care as part of the federal funding agenda.

Evaluation Of Locally Delivered 1.2% Atorvastatin Gel Versus 2% Melatonin Gel As Adjunctive To Non-Surgical Periodontal Therapy On Gcf Osteocalcin Level In Stage Ii Periodontitis Patients: A Randomized Controlled Trial, Sarah Gamal Moussa

Future Dental Journal

Abstract:

Objective: Atorvastatin (ATV) and melatonin have antioxidant and anti-inflammatory properties and were suggested to have positive effects when used in periodontitis cases. In periodontitis, osteocalcin (OC) was suggested to be a bone formation marker. Regarding bone turnover in periodontium, gingival crevicular fluid (GCF) osteocalcin levels are more accurate than salivary or serum levels.

Aim: The aim of the present study was to assess the effectiveness of local delivery of ATV gel and melatonin gel as adjuncts to scaling and root planing (SRP) in the treatment of stage II periodontitis patients.

Subjects and method: Thirty-six patients having stage II periodontitis ...


The Effect Of Doxorubicin And Thioridazine On Squamous Carcinoma Cell Line, bassant mahmoud moustafa 2021 future dental university

The Effect Of Doxorubicin And Thioridazine On Squamous Carcinoma Cell Line, Bassant Mahmoud Moustafa

Future Dental Journal

Abstract

Background: Head and neck squamous cell carcinoma (HNSCC) is one of the most common cancers occupying the sixth position worldwide. PI3k/Akt signaling pathway plays a significant role in regulating diverse cellular functions. This includes cell growth, proliferation and survival via inhibition of apoptosis, transcription and protein synthesis. One of the most acknowledged and approved chemotherapeutic agents is Doxorubicin (DOX) which is a non- selective class I anthracycline. In spite of DOX being one of the most acknowledged chemotherapeutic agents, its use has been limited by its toxic side effects and the development of chemoresistance. Nowadays, Thioridazine (TZ) which ...
