Relative abrasive potential of silica-based conventional and tablet dentifrices on enamel and dentin.
PLoS One
December 2024
Department of Restorative and Reconstructive Oral Care, Academic Centre for Dentistry Amsterdam (ACTA), Universiteit van Amsterdam and Vrije Universiteit Amsterdam, Amsterdam, The Netherlands.
Objectives: This in vitro study aimed to investigate the toothbrushing wear on both enamel and dentin surfaces of reference and commercially available dentifrices.
Methods: Bovine enamel and dentin blocks were initially polished and embedded within a resin composite in square shapes (10×8×6 mm3). Employing toothbrushes equipped with nylon bristles, a toothbrushing machine was utilized, subjecting dentin specimens (n = 36) to 500 brush cycles and enamel samples to 5000 brush cycles (n = 36).
Finite element analysis on implant-supported bar with different geometric shapes.
BMC Oral Health
December 2024
Department of Prosthodontics, Faculty of Dentistry, Chulalongkorn University, Pathumwan, Bangkok, 10330, Thailand.
Background: The selection guideline for the implant-supported bar connectors (ISBC) of hybrid denture is lacking. This study investigated the maximum von Mises stress (vMS), stress distribution, and displacement of various geometric ISBC in mandibular hybrid dentures, as well as the maximum principal stress (σmax) in the acrylic resin part, through finite element analysis.
Methods: Four different geometric cross-sectional patterns for mandibular ISBC-L, Y, I, and Square-of equal volume, based on the "All-on-4" concept, were created.
Evaluation of the effectiveness of panoramic radiography in impacted mandibular third molars on deep learning models developed with findings obtained with cone beam computed tomography.
Oral Radiol
December 2024
Department of Oral, Dental and Maxillofacial Radiology, Faculty of Dentistry, Ataturk University, Erzurum, 25240, Turkey.
Objective: The aim of this study is to determine the contact relationship and position of impacted mandibular third molar teeth (IMM) with the mandibular canal (MC) in panoramic radiography (PR) images using deep learning (DL) models trained with the help of cone beam computed tomography (CBCT) and DL to compare the performances of the architectures.
Methods: In this study, a total of 546 IMMs from 290 patients with CBCT and PR images were included. The performances of SqueezeNet, GoogLeNet, and Inception-v3 architectures in solving four problems on two different regions of interest (RoI) were evaluated.
Enhancing Nursing Competencies: An Assessment of Knowledge and Attitudes Toward Dental Trauma Management Among Nursing Students-An Interventional Study.
Nurs Rep
November 2024
Department of Stomatology, Faculty of Dentistry, University of Seville, 41009 Sevilla, Spain.
Introduction: Traumatic dental injuries (TDIs) present a significant challenge for healthcare professionals. Nurses, often the first point of contact for patients, may lack essential knowledge in dental trauma first aid, as noted in the existing literature.
Objective: To assess the knowledge of traumatic dental injuries (TDIs) among undergraduate nursing students before and after a targeted educational intervention.
Evaluation of the Effects of Thermal Aging on the Surface Roughness of Novel Tooth-Colored Restorative Materials.
Dent J (Basel)
December 2024
Department of Biomedical Sciences, School of Dental Medicine, University of Nevada, Las Vegas, NV 89557, USA.
The development of composite resins has led to novel materials aimed at improving restoration longevity. This study evaluates the surface roughness of four tooth-colored restorative materials after thermal aging. Eighty Class V preparations were restored with Admira Fusion, Beautifil II, Equia Forte HT, and Filtek.
