Testes de vitalidade para o diagnóstico pulpar de dentes traumatizados:revisão sistemática

Abstract

The aim of this systematic review was to evaluatethe effectiveness of vitality tests (Pulse Oximetry, and Flowmetry)for pulp diagnosis in traumatized comparing to sensibility tests. This review was registered at PROPERO’s database under the protocol CRD42018097361 and followed PRISMA recommendations (PICO strategy). The search strategy covered the following electronic databases Pubmed (Medline), Scopus, Web of Science, Cochrane Library, and Lilacs, and the list of published papers until May, 2018. The initial search identified 173 potencial papers. After removing duplicates, 77 articles were excluded. Title and abstract were read, resulting in the selection of 19 articles for full-text read. 5 articles were chosen for data extraction and qualitative analisys, using QUADAS-2, recommended by Cochrane. The vitality tests evaluatedwere Pulse Oximetry, Laser Doppler Flowmetry, and Ultrassonic Doppler Flowmetry, compared to cold, electric or both tests. Favorable results for vitality tests were shown in all the articles, howeverthe quality assessement revealed a high bias risk in all included studies. It was concluded that, due to a high bias risk and research design flaws, more studies are still needed to provethat Pulse Oximetry, Laser Doppler, and Ultrassonic Doppler Flowmetry have a good diagnostic accuracy and are better to sensibility tests in traumatized teeth.
