RESUMO Este estudo trata de uma revisão de literatura sobre a influência física e mental da hipnose no paciente Odontopediátrico no controle da ansiedade e da dor. Objetivou-se reunir as evidências encontradas em artigos de análise, pesquisa e revisões sistemáticas, compreendendo o período de 1994 até 2018. Para uma revisão descritiva foram selecionados portais na internet como Bireme, Pubmed, Periódicos Capes, por meio de palavras-chave como: “hypnosis”, “pediatric dentistry”, “fear”, “anesthesia”, “anxiety”, “children” “pain”. Foram apresentados de forma descritiva e concisa relevantes achados referentes às associações entre a hipnose e Odontopediatria e suas aplicações no controle da ansiedade e da dor. Concluiu-se que a hipnose pode aumentar a cooperação do paciente infantil e diminuir a resistência durante os procedimentos odontológicos dolorosos. Apesar dos resultados promissores observados, a hipnose em Odontopediatria ainda é pouco utilizada. Isto ocorre devido à ausência de conhecimento sobre o procedimento e a falta de treinamento durante a formação superior, demonstrando a importância da inclusão deste tema nos currículos dos profissionais de saúde e em suas práticas clínicas.

ABSTRACT This study is a literature review on the physical and mental influence of hypnosis in pediatric patient in controlling anxiety and pain. The objective was to gather the evidence found in the analysis of articles, research and systematic reviews, in the period from 1994 to 2018. For a descriptive review were selected Internet portals as Medicine®, Pubmed, Capes, using keywords like: “hypnosis”, “pediatric dentistry”, “fear”, “anesthesia”, “anxiety”, “children”, “pain”. Descriptively and concisely, they presented relevant findings regarding associations between hypnosis and dentistry and their applications in controlling anxiety and pain. It was concluded that hypnosis could increase the cooperation of the child patient and decrease the resistance during painful dental procedures. Despite the promising results observed, hypnosis in pediatric dentistry is still seldom used. This may be due to lack of knowledge about the procedure and the absence of formal education, indicating the importance of including Hypnosis in the healthcare professionals’ curriculum and their practices.

The present study evaluated the antimicrobial activity of three root canal irrigants against Enterococcus faecalis, Candida albicans, and Staphylococcus aureus. These microorganisms were incubated in the presence of citric acid (6 and 10%), EDTA (17%), and NaOCl (0.5, 1.0, 2.5, and 5.25%). Agar diffusion tests were performed and redox indicator resazurin was used to evaluate the inhibitory effect of the irrigants on the metabolic activity of these microorganisms. The mean diameters of the inhibition zones for the C. albicans cultures were 11.6 mm (17% EDTA), 5.5 mm (0.5% NaOCl), 12.9 mm (1% NaOCl), 22.1 mm (2.5% NaOCl), and 28.5 mm (5.25% NaOCl). The mean diameters of the inhibition zones for E. faecalis were 2.8 mm (1% NaOCl), 5.4 mm (2.5% NaOCl), and 8.3 mm (5.25% NaOCl). For S. aureus, the mean values were 8.0 mm (17% EDTA), 3.0 mm (1% NaOCl), 8.8 mm (2.5% NaOCl), and 10.0 mm (5.25% NaOCl). Most of the irrigant solutions presented effective antimicrobial activity against C. albicans. A high inhibitory effect on the metabolic activity of E. faecalis was detected when the microorganisms were incubated with 17% EDTA. The same result was reached when S. aureus was incubated in the presence of > 2.5% NaOCl. Altogether, these results indicate that 2.5% and 5.25% NaOCl are microbicides against S. aureus while 0.5% and 1% NaOCl are only microbiostatic against the tested bacteria. The 6% and 10% citric acid as well as 17% EDTA did not affect the viability of any of the assayed microorganisms.

The aim of this study is to assess the in vitro shear bond strength and adhesive remnant index (ARI) of one and two-step fluoridated orthodontic resins under conditions that simulate high cariogenic challenge. Edgewise brackets for maxillary central incisors were randomly bonded to 80 bovine incisors, using either TransbondTM Plus Color Change orthodontic resin and a self-etching primer adhesive (G1; n = 40) or Orthodontic Fill Magic with a conventional acid-etch technique (G2; n = 40). Each group of resin (n = 10) was divided into: immediate shear (A- pre-cycling control), immersion in artificial remineralizing saliva (neutral saliva) for 14 days (B- post-cycling control) and pH cycling with high cariogenic challenge (C- acid saliva with pH 5.5 and D- acid saliva with pH 4.5). After 14 days of pH cycling, the shear bond strength and ARI were evaluated. Considering the shear bond strength, TransbondTM Plus Color Change resin was stronger than Orthodontic Fill Magic when it was submitted to high cariogenic challenge (p < 0.05). Also TransbondTM Plus Color Change resin showed better adhesion to enamel than Orthodontic Fill Magic, in all situations evaluated (p < 0.05). It could be concluded that TransbondTM Plus Color Change resin presented better shear bond strength and adhesive remnant index when submitted to high cariogenic challenge, in comparison with Orthodontic Fill Magic.
