Revolutionizing Laminate Veneer Bonding: Laser Versus Acid Etching of Enamel.

Purpose: This study is designed to explore the effect of Er,Cr:YSGG laser tooth etching versus that of conventional tooth surface treatment on the shear bond strength of ceramic laminate veneers.

Methods: Seventy-six maxillary premolars were assigned to two groups (n = 38) according to the type of enamel surface treatment approach. Group 1: samples treated with the conventional acid-etch protocol.

Effect of preparation designs and CAD-CAM materials on step-stress fatigue survival of premolar partial coverage restorations: An in-vitro study with fractographic analysis.

Objectives: The growing trend of minimally invasive approaches has encouraged the application of partial coverage designs in restorative dentistry. This study aimed to evaluate the cyclic fatigue performance of different CAD-CAM materials used in various partial coverage designs for premolar restorations.

Methods: A freshly extracted upper premolar was prepared using a high-speed handpiece to create mesio-occluso-distal (MOD) cavities with standardized dimensions.

Biomechanical reinforcement by CAD-CAM materials affects stress distributions of posterior composite bridges: 3D finite element analysis.

Objectives: This 3D finite element analysis study aimed to investigate the effect of reinforcing CAD-CAM bars on stress distribution in various components of a posterior composite bridge.

Methods: A virtual model mimicking the absence of an upper second premolar was created, featuring class II cavity preparations on the proximal surfaces of the adjacent abutment teeth surrounding the edentulous space. Five distinct finite element analysis (FEA) models were generated, each representing a CAD-CAM reinforcing bar material: 3-YTZP (IPS.

Synthesis and characterisation of microcapsules for self-healing dental resin composites.

Aim: The purpose of this study was to i) synthesise TEGDMA-DHEPT microcapsules in a laboratory setting; ii) characterise the resultant microcapsules for quality measures.

Materials & Methods: Microcapsules were prepared by in situ polymerization of PUF shells. Microcapsules characterisation include size analysis, optical and SEM microscopy to measure the diameter and analyse the morphology of PUF microcapsules.

Performance of direct and indirect onlay restorations for structurally compromised teeth.

Statement Of Problem: Research is lacking on the restoration of structurally compromised posterior teeth using direct composite resin or indirect restorations.

Purpose: The purpose of this in vitro study was to measure the fracture resistance and microleakage of different onlay restorations fabricated by using conventional and digital computer-aided design and computer-aided manufacturing (CAD-CAM) to restore structurally compromised teeth.

Material And Methods: Mandibular molars (n=54) were prepared for onlay restorations.

Effect of Bleaching Agents on Discoloured Resin-Based Composites for Direct Restorations: A Systematic Review.

The purpose of the review was to assess the influence of office and home bleaching on the color durability after staining of resin-based composites (RCs) for direct restorations. A web-based search for possibly relevant scientific papers in the English language between January 2013 and August 2022 was conducted in the databases such as PubMed, Scopus, Cochrane Library, and EMBASE. In-vitro studies that explored the influence of in-office and other bleaching treatments on the discolored RC for direct restorations in extracted human teeth were included.

Dental Fiber-Post Systems: An In-Depth Review of Their Evolution, Current Practice and Future Directions.

The field of dental medicine is constantly evolving and advancing toward minimally invasive techniques. Several studies have demonstrated that bonding to the tooth structure, particularly enamel, yields the most predictable results. In some instances, however, significant tooth loss, pulpal necrosis, or irreversible pulpitis may limit the options available to the restorative dentist.

Properties of A Model Self-Healing Microcapsule-Based Dental Composite Reinforced with Silica Nanoparticles.

Aim: The purpose of this study was to evaluate the mechanical properties of an experimental self-healing dental composite model (SHDC) composed of SiO nanoparticles with varying percentages of triethylene glycol dimethacrylate (TEGDMA) monomer and ,-dihydroxyethyl--toluidine (DHEPT) amine microcapsules.

Materials And Methods: Microcapsules were prepared by in-situ polymerisation of PUF shells, as explained in our previous work. The model SHDC included bisphenol A glycidyl dimethacrylate (Bis-GMA:TEGDMA) (1:1), 1 wt% phenyl bis(2,4,6-trimethylbenzoyl) phosphine oxide (BAPO), 0.

A review and current state of autonomic self-healing microcapsules-based dental resin composites.

Objective: This study systematically reviews the literature on self-healing microcapsule technology and evaluates the biocompatibility of self-healing microcapsules and the efficiency of crack repair within resin-based dental composites.

Methods: An electronic search was carried out using the following databases: MedLine (PubMed), Embase, the Cochrane Library and Google Scholar. All titles and abstracts of the articles and patents found were analysed and selected according to the eligibility criteria.
