| Summary: | Objective: to perform an integrative review on the characteristics of materials used as cervical barrier in pulp revascularization, addressing the bioactivity and biocompatibility, as well as the drawbacks inherent to their use. Material and Methods: searches were made, in English and Portuguese, on the platforms PubMed and Google Scholar. The following keywords were used: (pulp revascularization OR pulp regeneration) and (Biodentine OR Endosequence OR MTA Angelus OR Calcium Enriched Mixture OR ProRoot MTA) and (drawing OR discoloration) and (Biodentine OR Endosequence OR MTA Angelus OR Calcium Enriched Mixture OR ProRoot MTA). Inclusion criteria were: articles published from 2008 to 2018, in vitro studies, clinical studies, literature review and case reports. Exclusion criteria were: articles that did not address the topic of revascularization. Results: the electronic search found 337 articles. After title analysis, 81 articles were selected for reading the abstracts, and 66 articles were excluded according to the inclusion criteria. After complete reading of the 15 articles, 2 were excluded for not addressing the topic of this study. The journals found were: Dental Materials, International Endodontic Journal, Journal of Applied Oral Science, Journal of Dentistry of Tehran University of Medical Sciences, Journal of Endodontics and Journal of Medical Sciences, from 2010 to 2017. Conclusion: bioceramic materials used as cervical barrier showed bioactivity and reduced toxicity. As an inconvenience to its use, coronal discoloration is reported in vitro due to MTA, Biodentine and Endosequence, and in vivo only due to MTA. In addition, mineralized tissue may form inside the root canal, possibly due to the bioactivity of these materials.
