An Accessible Microfluidic Platform for the Generation of Polarized Brain Organoids
Advanced Materials Technologies, EarlyView.This study presents an accessible double‐gradient microfluidic device that enables controlled morphogen delivery and spatially polarized differentiation in brain organoids. By integrating a pump‐free design and stable fabrication method, the platform generates dorsal–ventral neuronal asymmetry, offering a reproducible and versatile approach to model ...

Variations in acid-etch patterns with different acids and etch times
American Journal of Orthodontics and Dentofacial Orthopedics, 2001Research has shown that mandibular premolars have the highest rate of orthodontic bracket bond failure. Bond strength is thought to depend on the quality and quantity of enamel etch produced by the acid. Phosphoric acid is the most commonly used acid for etching before bonding.

The Acid-Etched Fixed Prosthesis
The Journal of the American Dental Association, 1982Acid-etched composite resins can be used to retain a cast fixed prosthesis. Such a prosthesis will be functional, esthetic, reversible, and economical.

Pyruvic acid as an etching agent
Journal of Oral Rehabilitation, 1976SummaryPhosphoric acid at different concentrations has been extensively used as an etching agent to improve bonding of dental materials to enamel surfaces. Recently attention has been drawn to the possible use of polyfunctional organic acids as conditioning agents.The object of this investigation was to determine the optimal concentration of pyruvic ...

The continuous brushing acid-etch technique
The Journal of Prosthetic Dentistry, 1987The continuous brushing of an acid-etching agent onto the enamel surface of an extracted tooth resulted in a more debris-free surface. SEM photomicrographs showed dissolution of some of the apatite crystals and a reduction in size of the remaining crystals, thus increasing the potential space between them for retention of unfilled composite.

Acid-etch canine riser occlusal treatment
The Journal of Prosthetic Dentistry, 1981Abstract A technique has been described where metal canine risers were attached to the lingual surfaces of maxillary canine teeth with acid-etch composite resin. The castings created a canine-protected occlusal scheme. No enamel needed to be removed from the teeth in their preparation for the restorations.

Acid‐etching of enamel cavity walls
Australian Dental Journal, 1984Abstract— The acid‐etched patterns produced on enamel cavity walls and the enamel tooth surface were investigated and the implications of these patterns on cavity preparation for composite resin restorations are discussed.The predominant pattern on enamel cavity walls is of obliquely and longitudinally sectioned prisms.

Acid etch bonded cast orthodontic retainers
American Journal of Orthodontics, 1979We have described a technique which involves the use of a cast orthodontic retaining appliance bonded by the acid etch technique and composite resin for semipermanent retention. The technique provides an alternative form of treatment which offers some unique advantages over previous retentive techniques.

Self-Etching Primers – an Alternative to the Conventional Acid Etch Technique?
Journal of Orofacial Orthopedics / Fortschritte der Kieferorthopädie, 2001The aim of the present in vitro study was to evaluate the bonding capacity of three self-etching primers (Clearfil SE Bond [SE], Clearfil Liner Bond 2V [CLB], Novabond [NOVA]) to enamel. Two adhesive systems with a separate phosphoric acid etching procedure (Gluma Comfort Bond [GLU], Kurasper F [KU]) served as controls.

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2007
AbstractObjective: To compare the effect of self‐etching primers and phosphoric acid on the wettability and roughness of smear layer‐covered and smear layer‐free dentin. Materials and Method: Three self‐etching primers (Clearfil SE Bond, AdheSE, and Xeno III) and 10% (w/w) phosphoric acid (H3PO4) solution were evaluated.
