Abstract
The technique of enamel microabrasion is considered an aesthetic alternative conservative and effective for stain removal or surface irregularities of the enamel and different materials or pastes can be used for this purpose Objetives: The objective of this study was to compare the efficiency of the technique of enamel microabrasion using two different pastes at removing hypoplastic stains by fluorosis. Methods: The female patient, 18 years, was submitted to enamel microabrasion, and in the right half of the maxilla was manipulated in the proportion of 1:1 by volume a paste of pumice (SSWhite) and 37% phosphoric acid (Etch Alpha, DFL), and in the left half of the maxilla used paste based on hydrochloric acid and 6.6% silicon carbide (Micropol, DMC Equipment Ltd.). In both hemi-arches was performed the same clinical protocol and repeated three times, by the application of 1.0 mm thickness of paste and realized the enamel microabrasion through mechanical friction with rubber cup at low speed for 10 seconds. Then, the teeth were polished with felt disc and diamond paste, and topical fluoride APF 1.23% for 3 minutes was applied. Results: The clinical outcome was similar for both hemi-arches, regardless of the used technique. The success in removing stains on tooth enamel is directly related to a correct diagnosis and accurate indication of microabrasion technique. Conclusions: It can be concluded that the two pastes used in the enamel microabrasion were effective for removing intrinsic stains from fluorosis, with similar results and with the re-establishment of aesthetics of the teeth involved.
Highlights
The enamel microabrasion technique is considered an aesthetic, conservative [1,2], and effective [3] procedure, which improves the appearance of teeth with decalcified enamel defects or superficial stains [3,4]
Even though these stains affected the mesial face of upper canines, the patient did not complain about these stains and the enamel microabrasion was the chosen treatment on the maxillary teeth, which appears on her smile
Regardless of the different paste types and the mechanical applications utilized, the current results showed that care is needed to choose microabrasion techniques because of the cost and the aggressiveness of the procedure
Summary
The enamel microabrasion technique is considered an aesthetic, conservative [1,2], and effective [3] procedure, which improves the appearance of teeth with decalcified enamel defects or superficial stains [3,4]. Since the microabrasion is performed on the surface of enamel, the smaller the lesion the higher the chances for a successful treatment [25] The purpose of this manuscript was to report a clinical case related to Flurosis treated with two distinct microabrasion pastes. After a detailed clinical history and examination, we obtained the diagnosis of mild fluorosis (Dean classification) [26] or TF degree 3 (Thylstrup and Fejerskov classification) [27] (Figure 1) Even though these stains affected the mesial face of upper canines, the patient did not complain about these stains and the enamel microabrasion was the chosen treatment on the maxillary teeth, which appears on her smile. Afterwards, the polishing was performed on the abraded enamel using felt discs with polishing paste (F Herjos – Vigodent, Rio de Janeiro, RJ, Brazil) (Figure 9), followed by a 1.23% acidulated phosphate fluoride gel application for 3 min (Figure 10)
