Enamel Micro-abrasion is a technique where an acid is used in combination with an abrasive to remove the superficial layer of enamel which has certain dental colorants within its structure. It is indicated as the treatment of choice for superficial enamel stains and is a technique which every dentist should offer to their patients. It is a simple, conservative, efficient and durable procedure.
Enamel microabrasion is effective in removing superficial enamel coloration defects. The technique has now also been shown to improve the appearance of enamel with surface texture irregularities. The method of microabrading teeth with surface texture defects is described, and several cases are documented.
Enamel microabrasion has become accepted as a conservative, nonrestorative method of improving the appearance of teeth with superficial dysmineralization and decalcification defects. This article reviews the technique of enamel microabrasion using a commercially available compound of hydrochloric acid and fine-grit silicon carbide particles in a water-soluble paste. It also describes a method of combining enamel microabrasion with carbamide peroxide home bleaching. Finally, it presents the cases of representative patients who underwent enamel microabrasion (alone or in combination with dental bleaching).
Enamel microabrasion was developed in the mid 1980's as a method of eliminating enamel discolouration defects and improving the appearance of teeth. Ten years after the method was developed, much has been learned about the best technique, long term results of treatment and microscopic changes to the enamel surface that have distinguishable clinical implications. In addition, certain patients can benefit from combined enamel microabrasion/tooth bleaching therapy that yields the most attractive cosmetic results. This article reviews the current status of enamel microabrasion one decade after its introduction to the profession. The latest treatment protocol is presented and photographic case histories document results of treatment. Clinical observations made over ten years are discussed.
Enamel microabrasion is used to eliminate superficial enamel discoloration defects. This article presents a comprehensive review of the enamel microabrasion method and its results. Current technique and materials are described and six cases are used to illustrate various aspects of the procedure. The learning objective of this article is to familiarize the reader with the state-of-the-art of enamel microabrasion and to report the latest laboratory research in the field.
Enamel microabrasion and carbamide peroxide-dentist supervised home applied dental bleaching are conservative methods of improving the appearance of teeth. Children and teens can benefit from these procedures. This article describes the step-by-step clinical technique of enamel microabrasion and a protocol for custom-tray-applied, home tooth-bleaching. Representative case histories are documented with photographs.
Enamel microabrasion is a proven method of removing superficial intrinsic enamel discoloration defects. The method is safe, easily performed, and causes no discomfort for the patient. A new commercially available microabrasion system has been introduced by Ultradent Products Inc. In addition, a new tooth isolation material is available, along with a visible light-activated in-office hydrogen peroxide solution. This article describes these new products and documents tooth-color correction for two young patients using this new tooth-color correction approach.
Enamel surfaces have been found to acquire a glasslike luster and an exceptionally smooth texture following enamel microabrasion procedures. A commercially available enamel microabrasion compound containing abrasive particles and a mild concentration of hydrochloric acid, when applied by rotary compression, simultaneously abrades and erodes (abrosion) the enamel surface. Human enamel surfaces were evaluated microscopically after routine enamel microabrasion procedures. The results show distinct evidence of enamel surface changes that have been described as the abrosion effect.
Enamel microabrasion is a proven method of removing intrinsic and superficial defects from teeth, establishing esthetics with minimal loss of dental enamel. This article reports one case in which two different microabrasion techniques were used to remove fluorotic stains from teeth.
Enamel surface "dysmineralization" can be defined as a disturbance in formation of the inorganic component of enamel during amelogenesis. Enamel microabrasion, a method of removing certain enamel dysmineralization and decalcification coloration defects, is described. In many cases, with insignificant and unrecognizable loss of enamel, superficial enamel discoloration defects can be permanently eliminated, improving the appearance of treated teeth.
A significant number of patients complain of discoloured teeth. The enamel microabrasion technique described in this article is a simple conservative method for improving the appearance of discoloured enamel.
A new material to be used in the procedure of enamel microabrasion has been recently introduced. Because the compound contains hydrochloric acid, the manufacturer recommends many safety precautions, especially use of the rubber dam. This case report documents the effect of the enamel microabrasion compound on the gingiva of one human subject and verifies the need for careful handling of the material.
Some teeth can best be treated by a combination of enamel microabrasion and resin composite bonding. This article outlines a protocol for treating patients with such teeth and documents one case, showing 5-year results.
Certain enamel coloration defects can best be eliminated by a combination of treatment methods. This report describes the treatment of two patients whose enamel discoloration was corrected with a combination of enamel microabrasion and patient-administered dental bleaching with a carbamide peroxide gel solution.

PURPOSE: To determine if microabraded surfaces inhibit Streptococcus mutans colonization. MATERIALS AND METHODS: Ten extracted molars were obtained and sectioned in half mesio-distally. The mesial side was treated with microabrasion (PREMA Compound). The distal surface was designated as the control site. A plastic tube was secured on each surface with resin composite, exposing a surface of 13.2 mm 2. S. mutans 10,499 was cultured in TSB-YE supplemented with 5% sucrose and 2.5% glucose was added to each secured site in addition to 50 microliters of cell suspension. Samples were incubated in a 5% CO2 chamber for 7 days at 37 degrees C. Samples were taken from each site, incubated with dextranase (75 micrograms 1 ml), sonicated, and vortexed to disrupt cellular aggregates as much as possible. Samples were then plated on Mitis-Salivarius agar using a spiral plating system. Enumeration of numbers of colonizing bacteria was achieved following standard spiral plating system methodology. RESULTS: The mean for the microabraded group was 1.12 x 10(2) cfu/tooth and for the control it was 1.15 x 10(4). Analyzing the data revealed a significant difference (P = 0.0188).
Two cases illustrate the technique of treating enamel discoloration and decalcification by beginning with bur cutting and completing with microabrasion compound. This eliminates texture defects caused by bur cutting and reduces treatment time.
