Microabrasion in tooth enamel discoloration defects: three cases with long-term follow-ups.

Sundfeld RH, Sundfeld-Neto D, Machado LS, Franco LM, Fagundes TC, Briso AL - J Appl Oral Sci (2014 Jul-Aug)

Bottom Line: Superficial irregularities and certain intrinsic stains on the dental enamel surfaces can be resolved by enamel microabrasion, however, treatment for such defects need to be confined to the outermost regions of the enamel surface.Dental bleaching and resin-based composite repair are also often useful for certain situations for tooth color corrections.Three case reports treated by enamel microabrasion were also presented after 11, 20 and 23 years of follow-ups.

ABSTRACT
Superficial irregularities and certain intrinsic stains on the dental enamel surfaces can be resolved by enamel microabrasion, however, treatment for such defects need to be confined to the outermost regions of the enamel surface. Dental bleaching and resin-based composite repair are also often useful for certain situations for tooth color corrections. This article presented and discussed the indications and limitations of enamel microabrasion treatment. Three case reports treated by enamel microabrasion were also presented after 11, 20 and 23 years of follow-ups.

Mentions: Stains and surface irregularities present in the enamel have led researchers to developmaterials and techniques for their removal10,12. Croll & Cavanaugh,in 198614 and Sundfeld, etal.35 (2007) proposed theapplication of a mixture of 18% hydrochloric acid and pumice to try to remove stainswith an insignificant loss of enamel (Figure 8).The treatment must be performed with a rubber dam in place, with the patient wearingprotective glasses. The mixture is applied with a wooden stick and firm finger pressurefor 5 seconds on the stained surface of the enamel, not surpassing a total of 15applications. Between each application, the enamel submitted to this technique should bewashed and dried.
