Enamel morphology after microabrasion with experimental compounds.

Background: Enamel microabrasion is an esthetic treatment for removing superficial stains or defects of enamel.

Aim: This study evaluated the roughness after enamel microabrasion using experimental microabrasive systems.

Materials And Methods: One hundred and ten samples (5 × 5 mm) were obtained from bovine incisors and divided into 11 groups (n = 10) in accordance with the treatment: Microabrasion using 6.

Evaluation of the effect of different methods of microabrasion and polishing on surface roughness of dental enamel.

Description Of The Technique: The microabrasion technique of enamel consists of selectively abrading the discolored areas or causing superficial structural changes in a selective way.

Objective: In microabrasion technique, abrasive products associated with acids are used, and the evaluation of enamel roughness after this treatment, as well as surface polishing, is necessary. This in-vitro study evaluated the enamel roughness after microabrasion, followed by different polishing techniques.

Effectiveness of dental bleaching in depth after using different bleaching agents.

Objectives: This study evaluated the effectiveness of low- and high-concentration bleaching agents on enamel and deep dentin.

Study Design: Stained bovine incisors fragments were randomized placed into 10 groups (n=5), according to the sample thicknesses (2.0 mm or 3.

Effects of mouthwashes on Knoop hardness and surface roughness of dental composites after different immersion times.

The aim of this in vitro study was to evaluate the effect of different mouthwashes on superficial roughness and Knoop hardness of two resin composites. Eighty specimens (6 mm Ø and 2 mm height) were prepared and divided into eight experimental groups (n = 10) according to the resin composites (4 Seasons and Esthet X), and storage solutions (G1 - Distilled water; G2 - Colgate Plax Overnight; G3 - Colgate Plax Alcohol Free; and G4 - Colgate Plax Whitening). The initial hardness and roughness readings (T1) were measured and then the specimens were stored in 2 mL of mouthwash for 12 h (T2) and 24 h (T3).
