Different Composite Veneer Surface Preparations for Metal Orthodontic Bracket Bonding: An In Vitro Study.
Int J Dent
January 2025
Department of Orthodontics, School of Dentistry, Mashhad University of Medical Sciences, Mashhad, Iran.
This research aimed to assess the shear bond strength (SBS) of metal brackets bonded to composite veneers using different surface preparations. One-hundred composite disks were divided into 10 different groups whereby each group combines a surface preparation (roughening or no roughening), etching agent (37% phosphoric or 9.5% hydrofluoric acid), adhesive protocol (self-etch or total-etch), and bonding agent (with or without G-Premio Bond).

Purpose: The aim of this study was to compare the wear and fracture resistance of single crowns produced from newly developed 3D printer resins used to produce permanent crowns and currently used composite CAD/CAM discs, after being thermomechanically aged in a chewing simulator.
Materials And Methods: A total of 112 stainless steel die models simulating mandibular left first molars were produced, 8 for each group. Single crowns were produced from 3 different discs (Grandio Voco [GR], breCAM HIPC [HC], and Shofu HC [SF]) by CAD/CAM milling method and manufactured from from 4 different permanent composite resins (Nexdent C&B MFH [ND], Permanent Bridge Saremco [PB], VarseoSmile Crownplus [VSC], and Şenertek P-Crown [PC]) using the 3D printing method.
INTRAORAL SCANNERS AND CONVENTIONAL IMPRESSIONS: A LITERATURE REVIEW.
Georgian Med News

2Private dental Clinic "Vurall Dent" Peja, Republic of Kosovo.
Introduction: Using digital technology, respectively the use of intraoral scanners has increased exponentially in recent years. Intraoral scanners have gained traction and widespread use in the field of dental prosthetics and orthodontics. While the use of these digital devices enables the detection of visible areas of error in order to allow clinicians to correct those areas immediately without a need of restarting the entire process from the beginning as it should be done in the conventional method and subsequent procedures.

Clin Exp Dent Res
February 2025
Department of Prosthodontics, Faculty of Dentistry, Ibb University, Yemen.
Objective: The use of vertical margin design in all-ceramic restoration has generated inquiries regarding its clinical efficacy under diverse dynamic oral conditions. This research aims to assess the marginal fit and fracture resistance of monolithic zirconia crowns featuring vertical margin design as opposed to those with conventional horizontal margin design.
Materials And Methods: Two metal dies were employed to generate replicated resin dies mimicking mandibular first molar preparation.
Comparative in Vitro Study on the Antimicrobial Efficacy of Endodontic Sealers Against Common Oral Pathogens.

Department of Odontology and Oral Pathology, George Emil Palade University of Medicine, Pharmacy, Science, and Technology of Targu Mures, 38 Gh. Marinescu Str., 540139 Târgu Mureș, Romania.
: Microorganisms are the leading cause of infections in the root canal system, contributing to the failure of endodontic treatments. This in vitro study aimed to compare the antimicrobial effects of four different endodontic sealers: Endomethasone N (Septodont, Saint Maur-des-Fossés, France), Sealapex (Kerr Corporation, Orange, CA, USA), AH Plus Jet (Dentsply DeTrey GmbH, Konstanz, Germany), and MTA Fillapex (Angelus, Londrina, Brazil). : The sealers were tested against common oral pathogens, including Enterococcus faecalis, Staphylococcus aureus, Escherichia coli, Candida albicans, and Streptococcus mutans, using the agar diffusion method.
