The paper presents the most comprehensive and large-scale global study to date on how higher education students perceived use of ChatGPT in early 2024. With a sample 23,218 from 109 countries territories, reveals that primarily used for brainstorming, summarizing texts, finding research articles, with few using it professional creative writing. They found useful simplifying complex information content, but less reliable providing supporting classroom learning, though some considered its...
Objective COVID-19 pandemic led to major life changes. We assessed the psychological impact of on dental academics globally and changes in their behaviors. Methods invited complete a cross-sectional, online survey from March May 2020. The was based Theory Planned Behavior (TPB). collected data participants' stress levels (using Impact Event Scale), attitude (fears, worries because extracted by Principal Component Analysis (PCA), perceived control (resulting training public health...
COVID-19 is a global pandemic affecting all aspects of life in countries. We assessed knowledge and associated factors among dental academics 26 countries.We invited to participate cross-sectional, multi-country, online survey from March April 2020. The collected data on regarding the mode transmission, symptoms, diagnosis, treatment, protection, treatment precautions as well participants' background variables. Multilevel linear models were used assess association between academics'...
Parental attitudes toward the importance of oral hygiene have an impact on formation their children's habits and prevalence diseases. Our aim was to assess association between parents' education socioeconomic status health. A cross-sectional study conducted years 2018 2020 in eastern province Saudi Arabia among primary school children. Two pre-calibrated dentists performed clinical examination children, a self-administered validated questionnaire obtained from parents. Clinical 589 children...
To date, various drugs as host modulating agents had been suggested adjunctive treatment modality in the therapy of chronic periodontal disease. In this study, anti-inflammatory effect subgingivally delivered nanostructured doxycycline gel (nDOX) was evaluated and compared to conventional (DOX) used adjunct scaling root planning (SRP) moderate periodontitis reduce probing pocket depth.Nanostructured prepared using spray-drying technique with chitosan (CH) a matrix polymer, followed by...
Background: Although oral rehabilitation with dental implants is a very promising and effective procedure, peri‐implantitis an emerging concern. Surgical non‐surgical methods have been applied to treat together various implant surface decontamination methods. However, there no consensus concerning the most treatment for peri‐implantitis. The aim of present study evaluate effects erbium‐doped:yttrium, aluminum, garnet (Er:YAG) laser, photodynamic therapy (PDT), titanium bur without citric...
Increasing attention has been paid to the possible link between periodontal disease and atherosclerosis over past decade. The aim of this study is investigate presence five periopathogens: Porphyromonas gingivalis (P.g.), Aggregatibacter actinomycetemcomitans (A.a.), Tannerella forsythia (T.f.), Treponema denticola (T.d.), Prevotella intermedia (P.i.) in atheromatous plaques obtained from carotid coronary arteries patients who underwent artery bypass graft surgery endarterectomy. Group I...
Treatment of peri-implantitis through several implant surface decontamination techniques have been reported, however, some them can negatively alter the or enhance more bacterial resistance. The aim this in vitro study was to evaluate by means Er,Cr:YSGG and diode lasers. Fifty micro-textured (MTX) dental implants were contaminated with Acinetobacter baumannii (n = 25) Pseudomonas aeruginosa 25). All then divided into five groups for procedure. In group I (GI), done an laser (2780 nm), while...
The aim of this study was to assess the influences different CAD/CAM ceramic compositions and thicknesses on surface roughness hardness restorations. Four ceramics were used in current study: lithium disilicate (LD), leucite reinforced (LE), advanced (ALD), zirconia-reinforced silicate (ZLS). Each group included 30 specimens subdivided into three (0.5, 1 1.5 mm thicknesses). microhardness measured for all using a testing machine, while non-contact optical profilometer at intervals (before...
Shade matching is a common challenge that dentists face during fabrication of esthetic dental restoration. Thus, the aim current study was to assess masking ability two types CAD/CAM ceramics for gaining high prosthesis. This in vitro used total sample size 66 lithium disilicate (LD) and leucite reinforced (LR) sub-grouped into three thicknesses: 0.5, 1, 1.5 mm. Nine shades natural dentin die materials were prepared as replica underlying tooth structure. The difference color (ΔE)...
Objective To evaluate the combined effects of azithromycin and varying concentrations cyclosporin on peripheral blood mononuclear cells (PBMCs) under lipopolysaccharide (LPS) stimulation. Materials methods PBMCs were isolated from four healthy donors treated with at (50, 200, 1,000 ng/ml) either alone or in combination (0.4 µg/ml), without 100 ng ml LPS derived Porphyromonas gingivalis. Total cell count, viability, lactate dehydrogenase (LDH) activity assessed day 1 3. While inflammatory...
Valproic acid (VPA) is known for its broad-spectrum antiepileptic effects and recommended generalized epilepsy, in contrast to phenytoin, which has a more limited spectrum. This study investigated the cytotoxic inflammatory responses phenytoin VPA peripheral blood mononuclear cells (PBMCs), with without bacterial lipopolysaccharide (LPS) stimulation. PBMCs from healthy donors were divided into 12 groups: control (Ctrl), (Phy), four concentrations of (Val-50, Val-75, Val-100, Val-200), LPS....
Palmitic acid (PMA) is abundantly present in substantial quantities within palm oil and manifests neurodegenerative propensities. Conversely, the ingestion of Hesperidin (HSD) correlated with a reduction inflammatory markers mediators. This investigation was meticulously devised to scrutinize protective potential HSD against deleterious repercussions PMA administration on cerebral cortex. A cohort comprising forty albino Wistar rats stratified into four groups, each receiving supplements...
Abstract Practical assessment in dental education is crucial for developing clinical competencies. This study investigated the effectiveness of action research (AR) and active learning strategies improving student achievement a preclinical restorative dentistry course among 58 third-year students. The intervention focused on teaching composite cavity preparation techniques through engagement participation. Using mixed-methods approach, data were collected over 10 weeks observations, surveys,...
The COVID-19 pandemic necessitated an abrupt shift to e-learning in higher education institutions worldwide ensure educational continuity during lockdowns. aim of this study was evaluate dental students' and educators' perceptions the lockdown their attitudes toward implementing blended learning post-pandemic education. A cross-sectional survey regarding e-teaching conducted at College Dentistry. Satisfaction attitude towards technology-based (TBL) were assessed. Two binary logistic...
Objective: Autogenous soft-tissue grafting is a commonly used procedure nowadays in dentistry. However, the prolonged healing time needed for donor site leads to increase patient's pain and discomfort. Statin has been observed be beneficial reducing bacterial burden, improving epithelization wound healing. The aim of this study was evaluate intra-oral topical application simvastatin/chitosan gel (10 mg/mL) over palatal following free gingival graft (FGG) procedure.Material methods: Subjects...
This study aims to assess differences in biofilm bacterial composition between patients with low and high caries. Patients without a medical problem no history of antibiotic use, mouth wash or fluoride application the previous 3 months were recruited. Caries was recorded at cavitation level; score calculated by national mean (dmft 4.8 DMFT 2.7). Pooled samples collected from mesial, distal, buccal, lingual, occlusal surfaces. Based on caries experience, individuals classified into both...
