Impact of altering the dispensing methods of resin-based cements on their physical and bonding qualities.

Statement Of Problem: Despite the advances in dental cements a significant gap remains in understanding how different dispensing and mixing techniques impact the physical properties of resin-based cements.

Purpose: The purpose of this in vitro study was to investigate how the physical properties, shear bond strengths (before and after thermocycling), and film thickness of resin-based cements change based on the dispensing and mixing methods.

Material And Methods: Eight different resin-based cements were evaluated, and specimens were prepared for each method (n=14) by following International Organization for Standardization (ISO) standards.

Effect of simulated toothbrushing on the surface roughness of LOCATOR abutments: An in vitro study.

Statement Of Problem: Studies evaluating the effect of toothbrushing and toothpaste abrasivity on the surface roughness of LOCATOR abutments are lacking.

Purpose: The purpose of this in vitro study was to compare the surface roughness of LOCATOR abutments before and after simulated toothbrushing with different toothpastes to make recommendations for the home care of patients with LOCATOR abutments.

Material And Methods: LOCATOR bone-level overdenture abutments (N=36) were analyzed with a confocal laser scanning microscope (Keyence VK-X1100) at ×5 magnification.

Biocompatibility of graphene oxide nanosheets functionalized with various amino acids towards mesenchymal stem cells.

Graphene and its derivatives have gained popularity due to their numerous applications in various fields, such as biomedicine. Recent reports have revealed the severe toxic effects of these nanomaterials on cells and organs. In general, the chemical composition and surface chemistry of nanomaterials affect their biocompatibility.

Minimally invasive approach in symptomatic aberrant right subclavian artery treatment.

Introduction And Importance: Anomalous right subclavian artery (ARSA) represents an uncommon anatomical deviation concerning the genesis of the right subclavian artery. As the predominant embryological irregularity of the aortic arch, it is clinically recognized as arteria lusoria (AL).

Case Presentation: This study, describe the instance of a 22-year-old female exhibiting a non-aneurysmal, symptomatic anomalous right subclavian artery (ARSA) coursing posteriorly to the esophagus, as evidenced by thoracic computed tomography (CT) imaging.

Comparative Analysis of Sensory Responses from Dental Implants vs Natural Teeth: An In Vivo Study.

To compare subjects' sensory responses to horizontal and vertical forces on tooth- and implant-supported restorations. In this prospective study, three protocols simulating the horizontal or vertical forces that occur during mastication were used to obtain subjective responses from subjects. These protocols included the measurement of horizontal force intensity during excursive movements and the identification of initial contact during guided and free vertical closure.
