Background/AimsDental avulsion is defined as the complete displacement of a tooth from its socket owing to trauma. The treatment outcome depends on storage of the avulsed teeth in media capable of maintaining the viability of periodontal ligament cells, when immediate replantation is not possible. To maintain the viability of periodontal ligament cells, plants can be used as a storage medium because of their pharmacological and phytotherapic properties. The aim of this study was to evaluate the effect of plants on the tissue repair following tooth replantation.MethodsThis systematic review was conducted according to the PRISMA guidelines and included articles collected in the Cochrane, LILACS, PubMed, Science Direct, Scopus and Web of Science databases, plus articles found in the grey literature. The articles were screened for partial reading using the Endnote and Rayyan platform. The methodology of studies was evaluated by using the OHAT and GRADE.ResultsIn the initial search, 2361 articles were obtained, only 51 articles were submitted to complete reading, and 35 articles were selected for the qualitative analysis. The evaluated plants had a potential effect on cell viability and proliferation. The articles evaluated mainly the action of plants on cells of the periodontal ligament. Propolis, coconut water and Aloe vera were the most common storage medium.ConclusionThe methodological limitations persist, and the evaluation of the pharmacological potential of plants on dental tissues still requires more research.

Health professionals and their patients are subject to cross‐contamination and potential exposure to harmful infectious diseases. A common form of cross‐contamination is through dental procedures without proper instrument care and lack of hand hygiene. The aim of this systematic review was to evaluate the published research on the adherence of educators and students in academic dental institutions to hand hygiene procedures. This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) and included articles collected in the Cochrane, LILACS, PubMed, Science Direct, Scopus, and Web of Science databases. The initial search identified 1,196 articles. Ultimately, three studies were included for qualitative synthesis and two for the meta‐analysis. The three articles had similar characteristics of observational hand hygiene research involving educators and dental students. In all three, hand hygiene among dental students did not reach 50% of the total number of opportunities, which is a troubling result. Although the hand hygiene rate of educators was higher than that of dental students, these findings point to a need to further promote hand hygiene to future professionals to avoid cross‐contamination between health professionals and patients.
