Bleaching and enamel microabrasion in the smile esthetics: a case report

Resumo

The color change of teeth is frequent in the dental
office and has important role in smile harmony. Objective: To
discuss through case report the dental bleaching technique associated
with enamel microabrasion to remove localized white spots on the
maxillary incisors and canines. Case report: Patient, female, aged
18 years, attended the Clinic of the University of Ribeirão Preto
complaining about the negative aesthetics of her smile due to the
presence of white spots on teeth #13, #12, #11, #21, #22 and #23.
After detailed anamnesis and clinical examination, the spots were
diagnosed as enamel demineralization caused by cariogenic challenge
occurred during the use of orthodontic brackets. Dental bleaching
technique with 38% hydrogen peroxide was applied followed by enamel
microabrasion with 6.6% hydrochloric acid and silicon carbide paste.
After absolute isolation, 1 mm thick paste was applied on enamel
stain with the aid of resin composite polishing abrasive rubber. Each
application was followed by copious washing and analysis of the
stain removal with wet enamel surface. In total, six applications of
10 seconds each were used. Finally, enamel polishing was executed
with felt discs and diamond paste, and topical application of fluoride.
Conclusion: It was concluded that bleaching associated with enamel
microabrasion technique is a safe, simple, and effective option for
solving the esthetics of teeth with white spots.
