Successful root canal treatment requires a thorough understanding of morphology. This study investigated the morphology and fine anatomical characteristics maxillary first premolars in an Iraqi sub-population using micro-computed tomography (micro-CT) classified Vertucci Ahmed et al. systems. A total 151 extracted were collected, cleaned disinfected. The collected teeth scanned micro-CT system. images segmented three-dimensionally (3D) reconstructed Mimics research software, for evaluation...
<title>Abstract</title> Background Contemporary ion-releasing restoratives have been developed to prevent secondary caries while maintaining the mechanical strength and esthetic qualities of conventional composite resins. Dental bleaching procedures may affect physical properties restorations. This study aimed evaluate effect agents on color stability these restoratives. Methods Forty-five disc-shaped specimens Activa Bioactive, Beautifil II LS, Cention-N, Riva LC HVGIC, Luna were fabricated...
This study investigated the effects of environmental pH on flexural properties ion-releasing restorative materials (IRMs), including giomer (Beautifil-Bulk Restorative - BB), alkasite (Cention N CN), bioactive composite (Activa AB) and resin-modified glass ionomer (Riva Light Cure -RV) restoratives. A bio-inert resin-based (Filtek Bulk-fill Posterior FB) served as control. Stainless steel molds were used to fabricate 40 beam-shaped specimens (12mm × 2mm 2mm) for each material. The finished,...
Artificial intelligence has been proven to improve the identification of various maxillofacial lesions. The aim current study is two-fold: assess performance four deep learning models (DLM) in external root resorption (ERR) and effect combining feature selection technique (FST) with DLM on their ability ERR identification. External was simulated 88 extracted premolar teeth using tungsten bur different depths (0.5 mm, 1 2 mm). All were scanned a Cone beam CT (Carestream Dental, Atlanta, GA)....
Training dentists today is challenging as they are expected to provide a wide range of dental care. In the provision good care, soft skills equally important clinical skills. Therefore in education development prime concern. This study sought identify when students paired their training. this perception study, four open-ended items were used elicit students' feedback on appropriateness using pairing an instructional strategy promote The most frequently cited teamwork (70%) and communication...
This study examined the influence of cariogenic environments on surface roughness ion-releasing restorative materials (IRMs). Custom-made stainless steel molds with holes 5 mm × 2mm were used to fabricate 60 disc-shaped specimens each following materials: Activa Bioactive (AV), Beautifil Bulk Restorative (BB), Cention N (Bulk-fill) (CN), and Filtek Z350XT (FZ) (Control). Baseline (Ra) measurements obtained using an optical 3D measurement machine (Alicona Imaging GmbH, Graz, Austria). The...
The objective of this study was to explore if matched (congruent) learning and teaching styles have an impact on the students' achievement. sample for comprised 310 English Major Students four lecturers from main campus Azad University. Both quantitative qualitative approaches were used in collection data. instrument Index Learning Styles Inventory by Felder Soloman (2006), observation notes interview schedule. results indicated that a positive achievement.The findings imply it is important...
This study is part of ongoing educational research conducted by the Department Conservative Dentistry, University Malaya, Malaysia, to evaluate perception clinical pairing. A thirteen-question survey was distributed 148 dental students after they had experienced four-handed dentistry. The objectives were identify advantages, disadvantages, and acceptance implementation pairing from students' point view. responses open-ended questions categorized into six main themes (areas interest):...
The association of Epstein-Barr virus (EBV) with oral cancer has been widely reported in the past.However, previous studies mainly focused on current infection EBV without acknowledging possibility past patients which may lead to development.The present study aims investigate correlation between infections Oral Squamous Cell Carcinoma (OSCC).Both Immunoglobulin M (IgM) and G (IgG) antibodies against were screened detect presence sera OSCC using Enzyme-Linked Immunosorbent Assay (ELISA).The...
The objective of this study was to investigate the effects oral environmental pH on viscoelastic properties bioactive restorative materials (BRMs) by using dynamic mechanical analysis. Stainless steel molds were used fabricate 40 beam-shaped specimens (12 × 2 mm) for each material. finished, measured, randomly divided into four groups (n = 10), and immersed in aqueous solutions 3.0, 5.0, 6.8, 10.0 at 37 °C seven days. then subjected analysis with a 5 N load frequency range 0.1-10.0 Hz. Data...
Objective: This study examined the impact of early biofilm on tooth surface, during assessment initial enamel erosion using swept-source optical coherence tomography (SS-OCT). Method and materials: Forty-five windows 2 × 4 mm2 were prepared 23 extracted human teeth. The specimens exposed to citric acid (pH 3.2) for 30 minutes randomly divided into three groups (n = 15): Group 1, no biofilm; 2, 1-day-old 3, 3-day-old biofilm. Specimens in Groups 3 inoculated with oral bacteria (Streptococcus...
The aim of this study was to assess the wear tungsten carbide burs and round rotary diamond instruments through measurements rake angle visual observations respectively under a field emission scanning electron microscope. Sixty short long head pear-shaped 18 that had been used complete < 5, > 5 10 cavity preparations (n=10/group) were selected from 3rd 4th year dental students, Faculty Dentistry, University Malaya. There two control groups consisting ten each. Two-way ANOVA analyse...

This clinical case report details the sequence of a 78-year-old male receiving prosthetic rehabilitation using an implant-supported screwretained fixed partial denture. Despite limitations imposed, aesthetic and functional demands patient were fulfilled by this rehabilitation. The importance detailed planning evaluation prior to implant surgery is essential, therefore ideally, it should be done same operator or team operators working together. Problems can arise when construction prosthesis...
