- Front lines of the COVID-19 pandemic: what is the effectiveness of using personal protective equipment in health service environments?: a systematic reviewPublication . Araujo, Cristiano; Guariza‑Filho, Odilon; Gonçalves, Flavio; Basso, Isabela; Schroder, Angela; Cavalcante‑Leão, Bianca; Ravazzi, Glória; Zeigelboim, Bianca; Neto, José; Sampaio Santos, RosanePurpose: This systematic review aimed to evaluate the effectiveness of the use of personal protective equipment (PPE) in closed environments, similar to waiting or exam rooms of healthcare facilities, in the face of exposure to a bioaerosol. Methods: Combinations of words were selected for six electronic databases and for the gray literature. To consider the eligibility of the studies to be included/excluded, the acronym “PECOS” was used: humans and/or experimental models that simulate aerosol (Population); aerosol exposure and the use of masks/respirators (exposition/intervention); controlled or not controlled (comparison); effectiveness of PPE and the receiver exposure (outcomes); and randomized clinical studies or not, observational or laboratory simulation studies (Studies design). Results: A total of 4820 references were retrieved by the search strategy. Thirty-five articles were selected for complete reading, of which 13 articles were included for qualitative synthesis. A surgical mask or N95 respirator reduced the risk of transmission, even over short distances. The use of masks, even those with less filtering power, when used by all individuals in the same environment is more effective in reducing risk than the use of respirators with high filtering power for only some of the individuals present. Conclusion: The use of mask in closed environments is effective in reducing the risk of transmission and contagion of a contaminated bioaerosol, with greater effectiveness when these devices are used by the source and receiver, regardless of the equipment’s filtering power.
- Is there scientific evidence of the mouthwashes effectiveness in reducing viral load in Covid-19?: a systematic reviewPublication . Cavalcante-Leão, Bianca; Araujo, Cristiano; Basso, Isabela; Schroder, Angela; Guariza-Filho, Odilon; Ravazzi, Glória; Gonçalves, Flavio; Zeigelboim, Bianca; Sampaio Santos, Rosane; Neto, José StechmanBackground: The aim of this research is to verify whether there is evidence in the literature regarding the decrease in viral load present in saliva after using three types of mouthwashes. Material and Methods: Clinical and/or in vitro experimental studies that have used mouthwashes as a form of intervention to reduce the viral load in saliva were included. Combinations of words and appropriate truncations were adapted for each of the seven selected electronic bases including grey literature. Results: The selection of articles was carried out in two phases by two independent reviewers. After removing duplicate articles, 1245 references were maintained, and 2 articles were included in the Systematic Review. Both studies were performed in vitro and tested the virucidal action of the PVP-I solution for mouthwash at two different concentrations, 1% without dilution and 7% with 1:30 dilution, on the SARS-CoV and MERS-CoV viruses. Both showed a viral reduction of ≥ 99.99% with 15 s exposure. Conclusions: Based on the evidence currently available in the literature, PVP-I, at concentrations of 1 and 7%, appears to be the most effective mouthwash for reducing the viral load of COVID-19 present in human saliva. However, the guidelines for dental care refer to the use of hydrogen peroxide but there is insufficient scientific evidence to support this recommendation.
- Psychosocial changes in patients submitted to orthodontic surgery treatment: a systematic review and meta‑analysisPublication . Basso, Isabela; Gonçalves, Flavio; Martins, Agnes; Schroder, Angela; Taveira, Karinna; Neto, José; Santos, Rosane Sampaio; Guariza‑Filho, Odilon; Araujo, CristianoObjective: This systematic review aims to answer the following question: What is the psychological impact of orthognathic surgery on patients with dentofacial deformities undergoing orthodontic-surgical treatment? Material and methods: The search was adapted for each of the following databases: American and Caribbean Center on Health Sciences (LILACS), Cochrane Library, Embase, Psychinfo, PubMed/Medline, Scopus and Web of Science, and gray literature using Google Scholar, OpenGrey, and ProQuest. The risk of bias was assessed using the Joanna Briggs Institute Critical Assessment Checklist. This study performed estimates of interest, random-effects meta-analyses, and calculated heterogeneity using Higgins inconsistency index (I2). Results: A total of 6751 references were found in all searches. After applying the eligibility criteria after full-text reading, 37 studies comprised the final qualitative synthesis. Thirteen studies were included in quantitative synthesis, and it was possible to meta-analyze data from the following questionnaires: GHQ-28, MMPI, RSES, and SCL-90-R. There was an improvement in psychological aspects related to depression, hysteria, self-esteem, anxiety, obsessive-compulsiveness, interpersonal sensitivity, paranoid ideas, and psychoticism (p < 0.05). Conclusions: Correction of dentofacial deformity through orthodontic-surgical treatment is associated with improvements observed in several psychological domains, especially in relation to depressive states. Clinical relevance: This result highlights the importance of surgeons and orthodontists in promoting adequate control of patients’ expectations and treatment goals taking into account the individual's psychological aspects.
