Background and aims: New dentin bonding agents and techniques have been developed to reduce microleakage and create higher bond strength. This invitro study compared the microleakage of three resinbased adhesives versus a GIC-based adhesive on class V composite restorations. Materials and Methods: Class V cavities were prepared on the buccal surfaces of 72 sound premolars, randomly assigned to ...

Background Immediate dentin sealing implies applying an adhesive system to directly after tooth preparation, before impression. The technique is universal (inlays, onlays, veneers, crowns) and well documented clinically experimentally. Different types of bonding agents (DBAs) are available on the market. Major differences lie in thickness hybrid layer overlaying resin (filled vs. unfilled/light...

Maybe it was due to a lack of printable topics for newspapers as usual at the beginning of a new year, but in early January we had several cumulated press interviews regarding regenerative issues in restorative dentistry. Focusing on scientific papers dealing with stem cells, dentin and enamel regeneration, several journalists from different newspapers and journals raised similar questions, whi...

Introduction: The purpose of this study was to test different sealer removal protocols following root canal filling before adhesive seal of access cavities. Material and methods: Forty single root teeth were selected for the study, prepared to size 60 taper .02, and filled with AH plus and a single gutta-percha cone size 55 taper .02. Excess sealer was removed with: ethanol-moisturised foam pel...

The aim of this study was to evaluate the effect of porosity of self-adhesive resin on the stress distribution, post retention and failure mode of fiber post cemented to human root dentin. Ten human central upper incisors with circular root canal were selected. They were sectioned with 15 mm and were endodontically filled. The roots were scanned using micro-CT after post space preparation for r...

We investigate disfluency distribution rates within different moves from an interactive task-oriented experiment to further explore the suggestion by Bortfeld et al. [1] and Nicholson [2] that different types of disfluencies may fulfill varying functions. We focus on disfluency types within moves, or speech turns, where a speaker initiates something compared to a response to such a move. We fin...

The aim of this in vitro study was to evaluate marginal leakage in class V restorations in primary teeth restored with amalgam, using three different techniques. Thirty maxillary anterior primary teeth, clinically sound and naturally exfoliated, were used. In group 1 (n = 10), two thin layers of a copal varnish (Cavitine) were applied. In group 2 (n = 10), Scotchbond Multi-Purpose Plus, a dual ...

In situ forming hydrogels with catechol groups as tissue reactive functionalities are interesting bioinspired materials for tissue adhesion. Poly(ethylene glycol) (PEG)–catechol tissue glues have been intensively investigated for this purpose. Different cross-linking mechanisms (oxidative or metal complexation) and cross-linking conditions (pH, oxidant concentration, etc.) have been studied in ...

OBJECTIVE To compare clinical and histologic healing of corneal lacerations repaired by sutures or a new polymeric adhesive. METHODS A central full-thickness 4.1-mm laceration was made in the right eyes of 60 white leghorn chickens. Half of the wounds were treated with biodendrimer polymer adhesive and half were closed with 3 interrupted 10-0 nylon sutures. Slitlamp examination was performed ...
