Antimicrobial efficacy of nanoparticle calcium hydroxide and silver nanoparticles on : An study.

Background: In root canal disinfection, intracanal medicaments play a vital role. Typical intracanal medicament, calcium hydroxide (CH), has the lowest efficacy against the biofilm of Enterococcus faecalis. Nanoparticles and their combinations may increase antimicrobial activity, making them better than conventional CH.

Proximal contact tightness of direct Class II composite resin restorations with various matrix systems: A systematic review.

Background: Restoring an ideal proximal contact in direct Class II composite resin restorations is challenging due to polymerization shrinkage, absence of condensability of composite materials, thickness of matrix bands, and the use of various separation techniques, retainers, and bands.

Aims: The aim of this study was to evaluate the proximal contact tightness that is achieved by various matrix systems used to restore a direct Class II cavity with composite resin restoration.

Methods: A systematic review was carried out according to the PRISMA 2020 statement guidelines.

A three-dimensional finite element analysis of stress distribution in maxillary central incisor with a horizontal mid root fracture after various management protocols.

Context: The incidence of root fractures is about 1.2%-7% in permanent teeth and horizontal mid root fractures are most common in maxillary anteriors.

Aims: This study aims to evaluate the stress distribution in a maxillary central incisor with mid root fracture after various management protocols using three-dimensional finite element (FE) analysis.

Comparative evaluation of apical bacterial extrusion following root canal instrumentation using different endodontic file systems: An study.

Aim: This study aims to evaluate the amount of apical extrusion of bacteria during root canal instrumentation using K3XF, Protaper Gold, Edge taper platinum, and Hyflex CM Rotary systems.

Materials And Methods: Sixty freshly extracted maxillary incisors teeth collected in saline. Access cavity prepared and canals were made free of bacterial and pulp.

Evaluation of antibacterial and antifungal activity of new calcium-based cement (Biodentine) compared to MTA and glass ionomer cement.

Objective: To evaluate the antibacterial and antifungal properties of calcium-based cement, Biodentine (Ca3SiO2), compared to commercial glass ionomer cements (GICs) and mineral trioxide aggregate (MTA).

Materials And Methods: Pellets of GICs, ProRoot MTA, and Biodentine were prepared to test the influence of these cements on the growth of four oral microbial strains: Streptococcus mutans, Enterococcus faecalis, Escherichia coli, and Candida albicans; using agar diffusion method. Wells were formed by removing the agar and the manipulated materials were immediately placed in the wells.
