Effect of surface conditioning protocols on the repair bond strength of resin composite to CAD/CAM blocks: Bioactive‐glass, silica‐coated alumina, or aluminum oxide?

European Journal of Oral Sciences, EarlyView.
Abstract This study evaluated the repair bond strengths of ceramic and hybrid ceramic CAD/CAM restorations following bioactive‐glass, silica‐coated alumina, and aluminum oxide surface treatments. Shear bond strength (SBS) tests, surface roughness, and scanning electron microscopic (SEM) evaluations were performed on 180 specimens (7×12×2 mm3 and 5×5×3 ...

Evaluation of compressive and adhesive strengths of a hybrid ceramic and 5Y‐PSZ zirconia cemented with three different materials

European Journal of Oral Sciences, EarlyView.
Abstract This study aimed to evaluate the compressive and adhesive strengths of ceramic restorations (PICN and 5Y‐PSZ zirconia) cemented with one of three types of cements: conventional glass ionomer cement (GI), resin‐modified glass ionomer cement (RM‐GI), and self‐adhesive resin cement (R).

On Networks with Active and Passive Agents [PDF]

arXiv, 2014
We introduce an active-passive networked multiagent system framework, which consists of agents subject to exogenous inputs (active agents) and agents without any inputs (passive agents), and analyze its convergence using Lyapunov stability.

Effectiveness of calcium hydroxide compared to hydraulic calcium silicate cements for direct pulp capping in managing deep caries in vital permanent teeth: A systematic review and meta‐analysis

International Endodontic Journal, EarlyView.
Abstract Background Direct pulp capping (DPC) is the least minimal approach for maintaining pulp vitality after pulp exposure. Besides calcium hydroxide (CaOH), hydraulic calcium silicate cements (HCSC) have increasingly been used for DPC. Objectives During the S3 level guideline development for material choice in DPC, we conducted a systematic review ...
