Marginal and internal adaptation of lithium disilicate partial restorations: A systematic review and meta-analysis.

Aim: The aim of this meta analysis was to evaluate the influence of the processing method on the marginal and internal gaps of lithium disilicate inlays/onlays.

Settings And Design: A systematic literature review was conducted using the PubMed/Medline, Embase, Scopus, and Cochrane Library databases. This review was registered on the PROSPERO platform.

Review of nano-technology applications in resin-based restorative materials.

Objective: Nanotechnology has progressed significantly and particles as small as 3 nm are being employed in resin-based restorative materials to improve clinical performance. The goal of this review is to report the progress of nanotechnology in Restorative Dentistry by reviewing the advantages, limitations, and applications of resin-based restorative materials with nanoparticles.

Materials And Methods: A literature review was conducted using PubMed/Medline, Scopus and Embase databases.

Effect of handling material on mechanical and optical properties of feldspathic porcelain.

Objective: To evaluate the optical, chemical, and mechanical properties of feldspathic porcelain after handling with different instrument materials.

Material And Methods: Feldspathic porcelain was manipulated with different spatula compositions: metal spatula (MS), plastic spatula (PS), and glass spatula (GS) for the fabrication of 30 (n = 10) disks. Contrast ratio (CR), translucency parameter (TP), and surface Knoop microhardness (KHN) were measured.

Influence of thickness and aging on the mechanical properties of provisional resin materials.

This study aimed to evaluate the flexural strength (FS) and modulus of elasticity (ME) of 2 provisional resins at different thicknesses and after different storage periods. A total of 80 specimens were made of 2 provisional restorative materials (n = 40): Dencôr (DC) or Protemp 4 (PT). The specimens in each material group were prepared in 2 different thicknesses (n = 20): 1.

Influence of the ferrule effect on the failure of fiber-reinforced composite post-and-core restorations: A systematic review and meta-analysis.

Statement Of Problem: The survival and/or success of post-retained restorations is influenced by the amount of residual coronal structure, known as the "ferrule effect."

Purpose: The purpose of this systematic review and meta-analysis was to evaluate whether the presence or absence of the ferrule effect influences the failure rate of fiber-reinforced composite post-and-core restorations.

Material And Methods: A comprehensive review of the literature was performed using the PubMed/Medline, Embase, Scopus, and Cochrane Library databases for articles published up to May 2018.

A new approach for Y-TZP surface treatment: evaluations of roughness and bond strength to resin cemen.

Objective: This study aims to evaluate the effect of sonochemical treatment on the surface of yttria-stabilized tetragonal zirconia (Y-TZP) before and after the final sintering.

Material And Methods: Twenty-eight Y-TZP discs were divided into four groups (n=7), according to surface treatment: PRE: pre-sintering sonication with 30% nominal power for 15 min; POS: post-sintering sonication with 30% nominal power for 15 min; JAT: air abrasion with 50-μm alumina particles; and CON: control group with no treatment. The POS and JAT groups were sintered before sonication and the PRE group after sonication.
