The aim of the study was to evaluate knowledge ER physicians with different specialties, experience and hospital sectors for management avulsed teeth in emergency rooms eight major hospitals Jeddah, Saudi Arabia. It also covers their attitude towards receiving further education on tooth avulsion management. A cross-sectional survey conducted at Jeddah from August December 2015. self-administered questionnaire consisting 31 multiple choice questions assessing both distributed 150 who were...
ABSTRACT By binding to its chemokine receptor CXCR4 on osteoclast precursor cells (OCPs), it is well known that stromal cell-derived factor-1 (SDF-1) promotes the chemotactic recruitment of circulating OCPs homeostatic bone remodeling site. However, engagement in pathogenic resorption remains be elucidated. The present study investigated a possible chemoattractant role macrophage migration inhibitory factor (MIF), another ligand for C-X-C type 4 (CXCR4), lytic lesion. To accomplish this, we...
Abstract Locally produced osteoclastogenic factor RANKL plays a critical role in the development of bone resorption periradicular periodontitis. However, because is also required for healthy remodeling, it plausible that costimulatory molecule upregulates production inflammatory periodontitis may be involved pathogenic loss processes. We hypothesized macrophage migration inhibitory (MIF) would play upregulating RANKL-mediated osteoclastogenesis lesion. In response to pulp exposure, and level...
Background: Postoperative pain is a potential adverse side effect of oral surgeries, and attempts should be made to prevent or minimize it. This study compares efficacy preemptive ibuprofen dexamethasone protocols for prevention control after surgical implant placement. Methods: prospective, double‐masked, parallel‐group, placebo‐controlled, randomized clinical trial included 117 patients with planned dental Patients were assigned receive one three different protocols: 1) 600 mg 1 hour...
Apical periodontitis (periapical lesions) is an infection-induced chronic inflammation in the jaw, ultimately resulting destruction of apical periodontal tissue. Toll-like receptors (TLRs) are prominent initial recognition pathogens. Our previous study showed that TLR4 signaling proinflammatory periapical lesions induced by a polymicrobial endodontic infection. In contrast, functional role TLR2 regulation tissue still not fully understood. Using deficient (KO), TLR2/TLR4 double (dKO), and...
The purpose of the study was to compare and histologically investigate pulpal response dentin bridge formation after direct pulp capping using recombinant amelogenin mineral trioxide aggregate (MTA). Recombinant protein MTA were used as materials in 120 teeth from eight mongrel dogs. Dogs sacrificed at two different evaluation times. Regenerative changes evaluated histologically. At weeks, contrast group, most group showed moderately formed hard tissue completely filling entire chamber....
This study aimed to test the biocompatibility and antibacterial properties of Salvadora persica (S. persica) extract, a natural product, as an intracanal medication in comparison with calcium hydroxide (Metapaste, META BIOMED, Cheongju, Korea). The pH values both materials were tested. S. persica extract Metapaste was determined using light microscopy MTT assays. action tested zone bacterial inhibition on four common species. In addition, administered 68 extracted single-rooted teeth...
Dental caries is an infectious oral disease caused by the presence of different bacteria in biofilms. Multidrug resistance (MDR) a major challenge dental treatment. Swabs were taken from 65 patients with Makkah, Saudi Arabia. cultivated on mitis salivarius agar and de Man, Rogosa, Sharpe (MRS) agar. VITEK 2 was used for identification isolated bacteria. Antibiotic susceptibility testing performed using commercial antibiotic disks. Ulva lactuca as reducing agent cellulose source to create...
The goal behind this work is to prepare, characterize, and study the antimicrobial behavior of zirconia (ZrO2) nanoparticles (NPs). Various techniques, such as X-ray diffraction (XRD), were used for studying mineralogical structure crystal size. microstructure chemical composition prepared particles analyzed using a scanning electron microscope attached with an energy-dispersive analysis (EDAX) unit. antagonistic ability against several Gram-negative Gram-positive bacteria, including...
The process of neovascularization during cell-based pulp regeneration is difficult to study. Here we developed a tube model that simulates root canal space and allows direct visualization the vascularization in vitro. Endothelial-like cells (ECs) derived from guiding human dental stem (DPSCs) into expressing endothelial cell markers CD144, vWF, VEGFR1, VEGFR2 were used. Human microvascular (hMVECs) used as positive control. DPSC-ECs formed tubules on Matrigel similar hMVECs. Cells mixed...
Abstract Staging platform (SP) uses a modified Gates Glidden (GG) to help retrieve separated instruments deep in the root canal. However, GG drills may cause damage or severe dentin loss. A 46-year-old male patient was referred endodontic postgraduate clinics complaining of pain on biting related mandibular right second molar (#47). The preoperative periapical radiograph #47 showed previously initiated canal treatment with an approximately 8-mm instrument apical third curved mesiolingual...
To explore the potential, challenges and needs for internship research activities in achieving scholar outcomes among graduates.A qualitative general assessment evaluation of an program was conducted at King Abdulaziz University, Faculty Dentistry (KAUFD), KSA, from December 2014 to February 2015 using focus groups interviews. The participants included: administrates, faculty, students. Data were transcribed analyzed following grounded theory.The two administrative personnel, 21 faculty...
Exams at the Faculty of Dentistry (KAUFD) are usually constructed to match King Abdulaziz University (KAU) policy a fixed 60% cutoff score, though they have never been tested or evaluated. The purpose this study was validate scores three final fifth-year written exams undergraduate Endodontic course assess whether were similar KAU regulation using Angoff rating method.This conducted between May 2014 and February 2015 Dentistry, University.Using method, evaluated by four senior faculty...
Abstract Background: Research plays a large role in the professional expectations of faculty all disciplines. In health professions, are expected to conduct research while caring for patients, educating learners, and carrying out major administrative roles. Given difficulty balancing these many responsibilities, it is sensible academic institutional officers seek understand factors that strongly relate productivity, measure members’ standing on those factors. The purpose study was...
