Experimental Study on Electro-Spark Additive/Subtractive Repair for Worn Cemented Carbide

Machines, 2023
Worn cemented carbide tool bits are often discarded because of the difficulty of their repair, resulting in a great deal of waste. Surface strengthening technology often extends the service life of worn tools.

Effect of Resin Coating on Dentin Bond Strength Under Immediate and Delayed Cementation Protocols

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This study aimed to evaluate the effects of resin coatings on bond strength using immediate and delayed cementation protocols. Materials and Methods One hundred twenty dentin specimens were assigned to four groups: Noncoated, TK–100B (a novel single‐bottle adhesive), Hybrid Coat II, and Clearfil SE bond 2. The specimens of the latter
