ABSTRACT BACKGROUND: Maintenance of oral microbiota balance is the simplest way to prevent infectious oral diseases, through controlling dental biofilm. Combined use of mouthwash and mechanical removal has been shown to be a very effective way for this. OBJECTIVES: To identify clinical studies comparing the antimicrobial effect and possible adverse effects and/or side effects of chlorhexidine-based mouthwashes with those of mouthwashes containing chlorine dioxide and/or polyhexanide, for controlling oral microbiota. DESIGN AND SETTING: Systematic review designed by the stomatology sector of postgraduation in applied dental sciences of Bauru Dentistry School, University of São Paulo, Brazil. METHODS: A systematic review was conducted using online databases (PubMed, Embase, Web of Science and Science Direct) up to April 8, 2020. The search was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: The studies included comprised eight articles published between 2001 and 2017. A total of 295 young adults, adults and elderly people were evaluated (males 44.75% and females 55.25%). Three articles compared polyhexanide with chlorhexidine and five articles compared chlorine dioxide with chlorhexidine. No studies comparing all three mouthwashes were found. The concentrations of the study solutions were quite varied, and all rinses had an antimicrobial effect. In four studies, it was stated that no side effects or adverse effects had been found. Three studies did not address these results and only one study addressed side effects and/or adverse effects. CONCLUSION: Mouthwashes containing chlorine dioxide and polyhexanide are viable alternatives to chlorhexidine, since they reduce oral biofilm and have little or no reported side or adverse effects.

Abstract The objective of this work was to correlate learning styles with reader´s metacomprehension strategies in university students. This cross-sectional study was carried out on 130 university students from a particular peruvian university. To determine learning styles, the Kolb inventory instrument was used, where it classifies as convergent, divergent, assimilator, and accommodator. For reader´s metacomprehension strategies, the Schmitt metacomprehension skills inventory instrument was used, according to the level of diagnosis it was classified as high, medium and low level. The statistical tests were carried out with the SPSS v. 22, a significance level of 5% was considered. In the sample 44.62% show a divergent learning style, followed by assimilator (24.61%), convergent (20.77%) accommodating (10%). In reader´s metacomprehension strategies, students showed medium level ability in 68.46%, followed by low level (22.3%) and high level (9.24%). When correlating learning styles and reader´s metacomprehension strategies, it was found that there is no statistically significant difference between ( ). It is concluded that the different learning styles are not related to the reader´s metacomprehension strategies in first year university students of the faculty of health sciences.

Resumen El objetivo del estudio fue correlacionar los estilos de aprendizaje con métodos de metacomprensión lectora en estudiantes universitarios. Este estudio transversal fue realizado en 130 estudiantes universitarios de una universidad peruana privada. Con la finalidad de establecer los estilos de aprendizaje, se utilizó el Inventario de Kolb, donde clasifica, los estilos de aprendizaje, en convergente, divergente, asimilador y acomodador. Para evaluar las habilidades de metacomprensión lectora se utilizó el instrumento del inventario de habilidades de metacomprensión de Schmitt, que permite diagnosticar en: nivel alto, medio y bajo. El procesamiento estadístico se realizó utilizando el programa SPSS v. 22, se consideró un nivel de significancia del 5%. En la muestra 44.62% muestran un estilo de aprendizaje divergente, seguido de asimilador (24.61%), convergente (20.77%) acomodador (10%). En las habilidades de metacomprensión lectora los estudiantes mostraron habilidad de nivel medio en 68.46%, seguido de nivel bajo (22.3%) y nivel alto (9.24%). Al correlacionar estilos de aprendizaje y metacomprensión lectora se encontró que no existe una diferencia estadísticamente significativa entre ( ). Se concluye que los diferentes estilos de aprendizaje no tienen relación con las habilidades de metacomprensión lectora en estudiantes universitarios de primer año de la facultad de ciencias de la salud.

SUMMARY Regional odontodysplasia is an uncommon dental anomaly that is not hereditary and has a still unknown etiology. The affected tissues are enamel and dentin, the primary teeth are affected, and sometimes in the permanent dentition of the same individual. This lesion may be confused with other lesions such as odontoma or teeth with another type of anomaly. The objective is to report a case of regional odontodysplasia in the deciduous and permanent dentition of a child, as well as to present the different diagnostic tools. The affected teeth showed clinical examination, such as hypoplastic teeth with a yellow-brown coloration. A panoramic radiograph and periapical radiographs, as well as an excisional biopsy, were essential to obtain a correct diagnosis, so as to be able to offer an adequate conduct for the preservation and predictability of the different types of dental rehabilitation treatments that this child could have in the years to come adulthood.

RESUMO A odontodisplasia regional é uma anomalia dentária, pouco comum, não hereditária e com uma etiologia ainda desconhecida. Os tecidos afetados são o esmalte e a dentina, são acometidos nos dentes decíduos e, as vezes na dentição permanente de um mesmo indivíduo. Esta lesão pode ser confundida com outras lesões como por exemplo o odontoma ou dentes com outro tipo de anomalia. O objetivo é relatar um caso de odontodisplasia regional na dentição decídua e permanente de uma criança, assim como apresentar as diferentes ferramentas diagnósticas. Os dentes acometidos mostravam-se ao exame clínico, como dentes hipoplásicos com coloração amarelo amarronzado. Uma radiografia panorâmica e radiografias periapicais, assim como uma biopsia excisional, foram essenciais para obter um diagnóstico correto, e assim poder oferecer uma adequada conduta para a preservação e previsibilidade dos diferentes tipos de tratamentos reabilitadores odontológicos que essa criança poderia ter nos próximos anos até a idade adulta.

Resumo Introdução: A disfunção temporomandibular (DTM) pode ter um grande impacto na qualidade de vida das pessoas. Objetivo: Esta revisão integrativa avaliou o impacto da DTM na qualidade de vida da população. Método: Uma busca eletrônica e manual foi realizada para identificar estudos que avaliaram o impacto da DTM na qualidade de vida. Após os critérios de inclusão e exclusão serem estabelecidos, seis artigos foram incluídos e avaliados de acordo com a qualidade de evidências utilizando o Newcastle-Ottawa. Resultados: Os estudos selecionados utilizaram instrumentos distintos para diagnóstico da DTM e da mensuração da qualidade de vida. Os instrumentos de diagnóstico de DTM foram o Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD), índice Anamnético de Fonseca, índice de Helkimo e índice Anamnético de Fonseca juntamente com RDC/TMD. Quanto à qualidade de vida, o instrumento mais utilizado foi o SF-36, seguido de Br-MPQ e WHOQOL-Bref. Conclusão: Os achados mostram que existe um impacto negativo da DTM na qualidade de vida, principalmente quanto a sua gravidade. Entretanto, futuras pesquisas são necessárias para confirmar esses resultados.

Abstract Introduction: Temporomandibular dysfunction (TMD) may have a major impact on quality of life. Objective: Thus, this integrative review assessed the impact of TMD on quality of life. Method: An electronic and manual search was conducted to identify studies that evaluated the impact of TMD on an individual’s quality of life. After the inclusion and exclusion criteria were met, seven articles were included and evaluated according to the quality of evidence using the Newcastle-Ottawa assessment. Results: The selected studies used different instruments to diagnose temporomandibular joint disorders and measure the quality of life. Only three studies used the RDC/TMD. As for quality of life, the most used instrument was the SF-36, followed by Br-MPQ and WHOQOL-Bref. Conclusion: The findings show that there is a negative impact of temporomandibular dysfunction on quality of life, especially regarding its severity. However, further studies are needed to confirm these results.
