Surface etching and subsurface demineralization of dental enamel induced by a strong acid
European Journal of Oral Sciences, 1977abstract – Intact enamel surfaces were exposed to 20 ml of 0.1% HCl for various periods. When the acid was unsaturated with respect to both hydroxyapatite and fluorapatite the surface enamel was etched away. With time the liquid close to the enamel became supersaturated with respect to fluorapatite but remained unsaturated with respect to ...

Sandblasted and acid-etched dental implants: a histologic study in rats.
The International journal of oral & maxillofacial implants, 2003Current literature has revealed that surface etching of endosseous implants can improve bone-implant contact. The aim of this study was to evaluate the differences in bone-implant contact (BIC) between sandblasted/acid-etched and machined-surface implants.Thirty-two Sprague-Dawley rats were used in this study. Two implant surfaces, Ecotek (sandblasted/

Abstract Acid-etching of hypocalcified portions of the human enamel produced debris consisting of acid-insoluble organic material on the etched surface. Ion-etching treatment completely removed this debris with minimal change in the mineral components.

Coating of Sandblasted and Acid-Etched Dental Implants With Tantalum Using Vacuum Plasma Spraying
Implant Dentistry, 2018The objective was to prepare tantalum (Ta)-coated sandblasted and acid-etched (SLA) dental implants using vacuum plasma spraying (VPS) and to analyze their morphologies.Twelve SLA implants were coated with Ta using VPS. The topographies of the coatings and Ta/SLA surface interfaces were examined using scanning electron microscopy.

This study has shown that the exposure of human dental enamel to acid solutions in vitro produces three basic etching patterns. In the most common, called type 1 etching pattern, prism core material was preferentially removed leaving the prism peripheres relatively intact. In the second, type 2 etching pattern, the reverse pattern was observed.

A potential limitation to clinical use of In-Ceram and In-Ceram Spinell dental ceramics has been the inability to etch fit surfaces.This study investigated a novel retentive system for In-Ceram and In-Ceram Spinell ceramics.The system, Bateman etch retention system, relies on incorporation of plastic chips on the surface of a specimen.

The efficacy of acid etching for removing contamination in layered dental restorations.
General dentistry, 2013Contamination between incremental layers of a composite resin restoration can occur during surgical procedures. The present study sought to evaluate how two decontamination treatments affected the shear bond strength between layers of a saliva-contaminated composite resin surface.

The effects of etching enamel with acid on human dental pulp. A preliminary study.
Oral surgery, oral medicine, and oral pathology, 1979Enamel acid-etching has become a widespread, popular clinical procedure in recent years. Numerous studies have investigated the nature of the acid-treated enamel. However, little or no information is presently available pertaining to the effects of acid treatment upon dental pulp tissue.
