Fracture Resistance of Chairside CAD/CAM Lithium Disilicate Partial and Full Coverage Crowns and Veneers for Maxillary Canines.

Objective: This study aimed to assess the fracture resistance of chairside computer assisted design and computer assisted manufacturing (CAD-CAM) lithium disilicate partial and full-coverage crowns and veneers for maxillary canines.

Methods And Materials: Forty-eight restorations for maxillary right canines (12 per group) were designed as follows: (1) partial crown with finish line in the upper middle third; (2) partial crown with finish line in the lower middle third; (3) traditional labial veneer; and (4) traditional full-coverage crown. Restorations were fabricated out of lithium disilicate (Amber Mill, Hassbio) using a chairside CAD-CAM system (Cerec Dentsply Sirona).

Comparison of Luting Cement Solubility: A Narrative Review.

Dental restoration success relies on the physical properties of luting cements. Luting cements fill the space between teeth and the restoration, provide retention and protection from occlusal forces, and act as a barrier to microleakages in the oral environment. This review aims to evaluate and compare the solubility of the three most used dental luting cements: glass ionomer (GI), resin-modified glass ionomer (RMGI), and resin cement (RC).

Wear resistance of 3D printed occlusal device materials.

Statement Of Problem: Three-dimensional (3D) printing offers an efficient method of producing occlusal devices; however, their wear resistance is poorly understood.

Purpose: The purpose of this in vitro study was to compare the wear resistance of flexible and rigid 3D printed occlusal device materials with milled and conventionally processed occlusal device materials.

Material And Methods: Blocks (n=8) of 3 flexible 3D printed materials (KeySplint Soft, NightGuard Flex 2, SmileGuard), 2 rigid 3D printed materials (KeySplint Hard, NightGuard Firm 2), 1 milled material (Ceramill A-Splint), 1 thermoform material (Erkoloc-Pro), 1 light-polymerized material (Eclipse Prosthetic Resin), 1 heat-polymerized material (Excel Formula Heat Cure Denture Base Material), and 1 autopolymerized material (Great Lakes Splint Resin Acrylic) were prepared and wet polished with 1200-grit SiC paper.

Understanding user experience and normative data in pharyngeal residue rating scales used in flexible endoscopic evaluation of swallowing (FEES): A scoping review.

Purpose: Pharyngeal residue rating scales are often used to rate pharyngeal residue observed during flexible endoscopic evaluation of swallowing. Despite the widespread use of pharyngeal residue rating scales, there is no data that has systematically explored user experience. The aim of this scoping review was to investigate specific reporting of user experience, user centred design principles, and normative data in the development of pharyngeal residue rating scales.
