Moccelini BS, et al. - Authors verified whether or not there was a correlation between pulp necrosis and crown discoloration in traumatized primary teeth through a systematic review and meta-analysis. They conducted a systematic literature search in PubMed/Medline, Lilacs/BBO, Scopus, Web of Science, Cochrane Library databases, and grey literature. Once the diagnosis of pulp necrosis was performed by limited criteria, findings suggested caution while considering the positive association between pulp necrosis and crown discoloration.
