| Resumo: | Internal tooth bleaching has external cervical resorption as an adverse effect. As a
result, it is recommended to create a cervical barrier, with suitable material, to prevent
the diffusion of hydrogen peroxide to the periodontal ligament. Several materials are
proposed for this, among them the resin-modified glass ionomer cement (RMGIC). The
objective of this work is to review the literature about the effectiveness of the use of
RMGIC as a cervical barrier during the bleaching of non-vital teeth. A bibliographic
search was carried out in the main databases: PubMed, Web of science, Scopus, and
in the virtual health library (VHL) databases, from 2012 to 2022, using the descriptors
“Tooth bleaching”, “Intracoronal Bleaching”, “Internal Bleaching”, “Glass Ionomer
Cements”. Six articles were obtained, which addressed the searched literature. 71,4%
of the analyzed studies presented favorable conditions for the use of RMGIC, and only
28,6% with unfavorable results for the glass ionomer. MTA and Biodentine showed
better results than RMGIC in 2 articles. RMGIC may be indicated for use as a cervical
barrier, when internal bleaching is performed with sodium perborate, alone or
associated with low concentration hydrogen peroxide. |
