The present study systematically reviewed the literature regarding the bond strength durability of zirconia ceramics to resin-based luting cements after application of different bonding protocols and aging conditions. Electronic searches in PubMed, Scopus, and Web of Science databases were performed for relevant literature published between January 1st 2015 and November 15th 2022. Ninety-three (93) English language in-vitro studies were included. The percentage of the mean bond strength change was recorded prior to and after artificial aging, and the weighted mean values and 95% confidence intervals were calculated. Bonding protocols were classified based on the combination of MDP/non-MDP containing cement/primer and surface pretreatment, as well as the level of artificial aging performed. Alumina sandblasting (SA) was identified as the most frequently used surface pre-treatment while an insufficient number of studies was identified for each category of alternative surface treatments. The combination of MDP cement with tribochemical silica coating (TSC) or SA yielded more durable results after aging, while the application of SA and TSC improved bond durability when a non-MDP cement and a non-MDP primer were used. TSC may lead to increased bond durability compared to SA, whereas MDP cements may act similarly when combined with SA or TSC.

BACKGROUND Different temperature conditions can affect the efficiency of irrigation solutions and consequently the ability of canal sealers to bond to root canal walls. The aim of this endodontic study was to evaluate the effect of irrigation solutions at different temperatures on the bond strength of a bioceramic-based root canal sealer. MATERIAL AND METHODS Root canal preparations were completed through irrigation with the following solutions: Group 1 was irrigated with 5 ml NaOCl (sodium hypochlorite) +5 ml EDTA (Ethylenediamine tetra-acetic acid) (22°C); Group 2 was irrigated with 5 ml NaOCl +5 ml EDTA (37°C); Group 3 was irrigated with 5 ml NaOCl +5 ml GA (Glycolic acid) (22°C); Group 4 was irrigated with 5 ml NaOCl +5 ml GA (37°C), Group 5 was irrigated with 20 ml Dual Rinse® HEDP (Etidronate) - NaOCl mixture (22°C); and Group 6 was irrigated with 20 ml of Dual Rinse® HEDP mixture (37°C).

Polydopamine (PD), inspired by the wet adhesion mechanism of mussel foot proteins, has emerged as a promising adhesive material with wide-ranging applications. This study aimed to compare the adhesive properties of PD and Glass Ionomer Cement (GIC) on enamel and dentin substrates, evaluating PD's potential as an alternative adhesive in dental practice. A total of 120 human premolars were prepared, with 80 teeth allocated for Scanning Electron Microscopy (SEM) analysis and 40 teeth reserved for shear bond strength testing.

Background: Limited reports are available regarding bonding of universal adhesives to primary teeth' enamel.
Aim: To evaluate the effect of application mode and aging on microtensile bond strength (μTBS) of universal adhesives to primary enamel.
Design: Ninety-six human primary molars were randomly assigned to three groups: SU: Scotchbond Universal (3M); CU: Clearfil Universal Bond Quick (Kuraray Noritake); iBU: iBond Universal (Heraeus Kulzer), then subdivided according to phosphoric acid etching time into three subgroups (SG): SG1: 0s; SG2: 15s; SG3: 30s.

HBT-DPI was a single-molecule multi-conformational fluorescent material and had unique applications for hydrophobic/hydrophilic mapping on large-scale heterogeneous surfaces. In this paper, the different proton transfer processes and luminescence mechanisms of HBT-DPI in Dichloromethane (DCM, no hydrogen bond (HB) receptor) and N, N-Dimethylformamide (DMF, HB receptor) solvents were systematically studied. Using the quantum chemistry method, the stable structures of HBT-DPI in two solvents were determined based on the Boltzmann distribution.

The development of high-performance electrocatalysts for hydrogen evolution reaction (HER) in different pH conditionsis pivotal in producing green hydrogen, but remains challenging. Herein, we regulate the p-d orbitals hybridization between B and Pt for effective and durable HER at all pH ranges by controlling the inserted B atom. Consequently, the optimized B-doped Pt catalysts with 20 at.
