Microabrasão do esmalte dental comparando técnicas que utilizam ácido clorídrico 18% e ácido fosfórico 37% : estudo de caso.

Abstract

Dental fluorosis is a poor enamel formation that occurs when teeth are developing due to excessive ingestion of fluoride, either by water, food or by products containing fluoride, such as toothpaste. Enamel microabrasion is considered one of the main treatment options for cases of fluorosis, as it is one of the most conservative, reliable, fast and safe techniques. An acid/abrasive mixture is used to remove the superficial spots and irregularities present in the dental enamel, promoting a satisfactory aesthetic result, of long duration, without affecting the dental pulp and the periodontal tissues, with minimal sensitivity and wear of the dental structure. The objective of the present study was to evaluate the differences in the microabrasion technique of enamel with 37% phosphoric acid and the microabrasion technique of enamel with 18% hydrochloric acid, both associated with pumice stone, through a clinical case report carried out in the Clinic of Dentistry of the University of Santa Cruz do Sul - UNISC. The case was registered, through photographs, from the beginning until the completion of the treatment techniques. Both results were satisfactory, promoting aesthetics to the teeth with fluorotical stains. However, the microabrasion technique of enamel with 18% hydrochloric acid promoted a faster result, with fewer applications. While the microabrasion technique of enamel with 37% phosphoric acid required more applications to reach the same resolution.
