Evaluation of Prosthetic Complications with Metal-Acrylic Resin Implant-Fixed Complete Dentures: A Medium- and Long-Term Retrospective Analysis with Up to 13 Years of Follow-up.

Purpose: To present prosthetic complications observed in the medium and long term in patients treated with metal-acrylic resin implant-supported fixed complete dentures (MAIFCDs).

Materials And Methods: A total of 87 patients who were treated with MAIFCDs were included. Acrylic resin (denture teeth and base) fracture, screw loosening (prosthetic or abutment), screw (prosthetic or abutment), and framework fracture were analyzed for descriptive statistics.

Illuminant effect on the coverage error of a gingiva-colored composite resin shade guide.

Statement Of Problem: Dental clinicians face challenges when selecting the proper gingiva-colored composite resin.

Purpose: The purpose of this study was to evaluate the coverage error (CE) of a gingiva-colored dental composite resin shade guide with regard to the optical characteristics of the attached gingiva of a selected population under 2 different illuminants: Commission Internationale de l'Eclairage (CIE) illuminants A and D65.

Material And Methods: The spectral reflectance (SR) values of 12 shade tabs of a gingiva-colored composite resin (Amaris gingiva) were measured at 3 different locations without a backing by using a spectroradiometer and an external light source at wavelengths of 380 to 780 nm at 2-nm intervals.

Effect of simulated mastication on the surface roughness of three ceramic systems.

Statement Of Problem: Zirconia complete coverage crowns are being widely used as restorations because of their high strength and improved esthetics. Data are sparse about the change in surface roughness of this ceramic material after repeated mastication cycles of opposing enamel.

Purpose: The purpose of this study was to investigate changes in the surface roughness after being subjected to 3-body wear-opposing human enamel of 3 types of ceramics: dense sintered yttrium-stabilized zirconia (Z); lithium disilicate (L); and a conventional low-fusing feldspathic porcelain (P) treated to impart a rough, smooth, or glazed surface.

Factors related to the willingness of Palestinian dentists to treat patients with blood-borne diseases.

This study aimed to explore, using groups of simulated patients, the willingness of Palestinian dentists to treat patients with blood-borne diseases. Simulated patients conducted a telephone survey of a random sample of dentists registered with the Palestinian Dental Association. A random system was used to assign dentists to one of two groups, in which simulated patients randomly identified themselves with either human immunodeficiency virus (HIV) or hepatitis B virus (HBV) and asked for a dental appointment.

Three-body wear potential of dental yttrium-stabilized zirconia ceramic after grinding, polishing, and glazing treatments.

Statement Of Problem: Zirconia complete-coverage crowns are being widely used as restorations because of their improved esthetic characteristics. Data about the enamel wear potential of this ceramic after chair side adjustments are sparse.

Purpose: The purpose of this study was to investigate the 3-body wear of enamel opposing 3 types of ceramic (dense sintered yttrium-stabilized zirconia; Crystal Zirconia; DLMS) (Z), a lithium disilicate (IPS e-max CAD; Ivoclar Vivadent) (E), and a conventional low-fusing feldspathic porcelain (VitaVMK-Master; Vita Zahnfabrik) (P), treated to impart a rough, smooth, or glazed surface.

Development and evaluation of an interactive dental video game to teach dentin bonding.

Written and clinical tests compared the change in clinical knowledge and practical clinical skill of first-year dental students watching a clinical video recording of the three-step etch-and-rinse resin bonding system to those using an interactive dental video game teaching the same procedure. The research design was a randomized controlled trial with eighty first-year dental students enrolled in the preclinical operative dentistry course. Students' change in knowledge was measured through written examination using a pre-test and a post-test, as well as clinical tests in the form of a benchtop shear bond strength test.
