ABSTRACT Objective To determine the prevalence of stress among clinical students from Faculty Dentistry, King Abdul Aziz University, Jeddah. Materials and methods A cross-sectional descriptive study was carried out in May 2012 on fourth, fifth sixth year dental Jeddah, using a modified form environment (DES) questionnaire. total 353 questionnaires were distributed incomplete excluded study. SPSS version 15 used to do statistical analysis. Results asked complete questionnaire 232 (65.7%)...
ABSTRACT Objective To study the effect of three energy drinks on color stability nanofilled composite resins after different periods aging time. Materials and methods Composite resin disks, 6 mm diameter, 3 thickness were prepared from Filtec Z350 XT, Tetric EvoCeram, Z250 XT. Specimens each material tested with Red Bull, Bison Power Horse distilled water as a control. stored at 37°C in dark containers for 1, 7, 30 60 days. Color was assessed CIELAB using colorimeter before storage period....
Cell fusion-mediated formation of multinuclear osteoclasts (OCs) plays a key role in bone resorption. It is reported that 2 unique OC-specific fusogens [i.e., OC-stimulatory transmembrane protein (OC-STAMP) and dendritic cell–specific (DC-STAMP)], permissive fusogen CD9, are involved OC fusion. In contrast to DC-STAMP-knockout (KO) mice, which show the osteopetrotic phenotype, OC-STAMP-KO mice no difference systemic mineral density. Nonetheless, according ligature-induced periodontitis...
To analyze bite force distribution in subjects with different occlusal characteristics.This prospective study included 132 candidates (50 males, 82 females) seeking orthodontic treatment, who were divided into four groups based on Angle's classification of malocclusion. T-Scan® III Version 7.0 was used to record their relative forces, which compared using gender, classification, overjet, overbite, space analysis, sagittal, and transverse skeletal relations variables.ANOVA revealed...
Objective. This study aimed to evaluate the effect of different storage solutions that simulate acidic, alkaline, and sebum conditiions on physical properties pigmented (colorant elastomer) cosmesil M511 maxillofacial prosthetic material. Materials Methods. Sixty specimens were prepared according manufacturer's instructions tested before after immersion conditions for six months at 37 °C. The following tests performed: color changes (group I), solution absorption II), surface roughness III),...
Objective The purpose of this in vitro study is to compare the flexural strength and Weibull modulus 5 different monolithic computer-aided design/computer-aided manufacturing (CAD/CAM) ceramics. Methods A total 50 specimens were fabricated, 10 from each following materials: lithium disilicate-based ceramic (IPS e.max CAD), zirconia -reinforced lithium-silicate (Vita Suprinity), leucite-based glass Empress two zirconia-based ceramics (Zenostar CopraSmile). 4 mm wide, 2 thick, 16 long....
To analyse occlusion time, occlusal balance and lateral scheme in subjects with various dental skeletal characteristics.A total of 132 (50 males 82 females) seeking orthodontic treatment were included this prospective study. Using the T-Scan III version 7.0 (Tekscan Inc, South Boston, MA, USA), schemes recorded compared gender, Angle's classification, overjet, overbite, space analysis, transverse relations. ANOVA, t test contingency tables analyses performed. Statistical significance was set...
The objective of this study is to investigate the correlation between psychomotor skills and academic performance dental students.Didactic preclinical scores were collected for students who graduated from Faculty Dentistry, King Abdulaziz University, Jeddah, Saudi Arabia, in 2011. Three courses (Dental Anatomy, Removable Prosthodontic Denture, Orthodontics) selected. Correlations comparing didactic practical done total samples, then males females separately.There was no significant three...
Objective: To compare efficacy, side effects, patient compliance, and preference between two types of custom-made mandibular advancement appliances (MAAs) in the treatment patients with mild to moderate obstructive sleep apnea (OSA).Methodology: This prospective, randomized, crossover study 12 OSA compared a titratable non-titratable MAA. Each was fitted both random order washout period weeks. Efficacy, were evaluated by questionnaire. All underwent overnight home recordings prior after use...
Aim: The aim of this study was to evaluate surface and mechanical properties bulk fill composite compared conventional incremental composites.Materials methods: composites were Filtek Bulk Fill, Sonic SDR Smart Dentin Replacement Tetric-N-Ceram Fill while the ones Z350 × T Herculite XRV Ultra. Surface roughness wettability measured using profilometer (Bruker) drop shape analyzer (Kruss), respectively. hardness top bottom Micromet 6040 (Buehler). For test, universal testing machine used under...
This cross-sectional study compared and contrasted the morphological characteristics of Class I, II III malocclusions in an adolescent Saudi population. Adolescent Saudis with Angle's were selected from orthodontic patients' records. Angular linear measurements between three groups. Cephalometric analysis was performed using VistadentOC® software. Multifactorial ANOVA for angular within Orthodontic records 300 patients included. There no significant difference groups age distribution...
ABSTRACT Introduction Immediate implant-loading protocol has progressed because of various clinical advantages offered by this treatment approach. However, available studies on edentulous patients are still few compared to those in which delayed implantloading was applied. Aim This prospective study evaluate the implant survival rate and peri-implant tissue response a group who received two unsplinted immediately loaded dental implants mandibular anterior region retain complete overdenture...
This longitudinal study was aimed to investigate the association between didactic grades and practical skills for dental students whether can reliability predict students' performance.Didactic graduates from Faculty of Dentistry, King Abdulaziz University, years 2009 2011 were collected. Four courses selected: Dental Anatomy, Operative Prosthodontics, Orthodontics. Pearson product-moment correlation analyses scores conducted.There only a significant Anatomy course (P<0.001). There also all...
ABSTRACT Background Thermoplastic resin polymers are widely used in medicine due to their biostability and hypoallergenic properties, making them a possible alternative poly-methylmethacrylate (PMMA). The current research examined the microstructure of rapid injection molding system thermoplastic for construction flexible denture compared with that heatcured PMMA. Materials methods A total 40 disk-shaped specimens (25 mm diameter 3 thickness) were prepared divided into two groups 20 disks...
During the past few decades, unalloyed titanium has been extensively used as a material of dental implant-supported restorations but it cause gingival discoloration and unnatural appearance surrounding soft tissue. Currently, yttrium oxide partially-stabilized zirconia (Y-TZP) is ceramic special interest because its superior mechanical properties. This study was carried out with four one piece zirconium implants embedded on standard acrylic resin mandibular edentulous model, abutment implant...
