ABSTRACT

This review describes the geographical distribution, botanical data, popular use, chemical composition, pharmacological activities and genetic aspects related to Eugenia luschnathiana, a native Brazilian plant popularly known as "bay pitomba". E. luschnathiana leaves are characterized morphologically by the presence of a petiole, an attenuated base, acuminated apex, elliptical shape, and parallel venation. The major chemical compounds found in E. luschnathiana are sesquiterpenes. Literature reports showed that E. luschnathiana extracts have antioxidant properties and antimicrobial activity against Gram-negative and Gram-positive bacteria. The extractsfrom the leaf, fruit and stem, and a concentrated residual solution of its essential oil, displayed negligible toxicity. Lastly, a cytogenetic analysis indicated that some markers can be used for the study of genetic diversity, population structure, and genetic improvements. The information available on E. luschnathiana supports the hypothesis that this plant may be a source of compounds with promising pharmacological activity.


Esta revisión describe la distribución geográfica, datos botánicos, uso popular, composición química, actividad farmacológica y el análisis genético de Eugenia luschnathiana, una planta originaria del Brasil conocida popularmente como "pitomba da baía". Las hojas de E. luschnathiana se caracterizan por la presencia de pecíolo, base atenuada, ápice acuminado, forma elíptica y venación paralela. Su composición química presenta mayormente sesquiterpenos. Los informes en la literatura muestran que los extractos de E. luschnathiana presentan propiedades antioxidantes y actividad antimicrobiana contra las bacterias Gram-negativas y Gram-positivas. Los extractos de la hoja, fruto y tallo, y una solución residual concentrada del aceite esencial, presentaron baja toxicidad. Por último, un análisis citogenético indicó que algunos marcadores pueden utilizarse para estudios de diversidad genética, estructura poblacional y mejoramiento genético. Las informaciones disponibles acerca de E. luschnathiana proponen la hipótesis de que esta planta puede ser una fuente de compuestos con actividad farmacológica prometedora.

ABSTRACT

Abstract We aimed to evaluate the orofacial antinociceptive effect of geraniol in mice and its molecular anchorage mechanism. Seven mice per group (probabilistic sample) were treated with geraniol (12.5, 25 and 50 mg/kg, i.p.), morphine (6 mg/kg, i.p.) and vehicle (saline + Tween 80 at 0.2%, i.p.) 30 minutes prior to the beginning of the experiment. Injecting glutamate (25 μM), capsaicin (2.5 μg) and formalin (2%) into the right upper lip (perinasal) of the mouse induced nociception. Behavioral analysis of the animals considered the friction time (in seconds) of the mentioned region using hind or front paws by a researcher blinded to the treatment groups. The statistical analysis was performed blindly, considering α = 5%. The results showed that in the glutamate and capsaicin tests, concentrations of 25 mg/kg and 50 mg/kg presented antinociceptive activity (p < 0.005, power> 80%). In the formalin test, geraniol was able to reduce nociception at a concentration of 50 mg/kg (p < 0.005, power> 80%). In the molecular anchorage study, high values of binding between the evaluated substance and receptors of glutamate were observed (metabotropic glutamate receptor, -87.8501 Kcal/mol; N-methyl-D-aspartate, -86.4451 Kcal/mol; α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid, -85.6755 Kcal/mol). Geraniol presented orofacial antinociceptive activity, probably by interacting with glutamate-related receptors.

ABSTRACT

Abstract Objective: This study sought to identify the differences between the oral changes presented by patients with solid and hematologic tumors during chemotherapeutic treatment. Methodology: This is an observational, prospective and quantitative study using direct documentation by follow-up of 105 patients from 0 to 18 years using the modified Oral Assessment Guide (OAG). Of the 105 patients analyzed, 57 (54.3%) were boys with 7.3 years (±5.2) mean age. Hematologic neoplasms accounted for 51.4% of all cases. Results: Voice, lips, tongue, and saliva changes were not significantly different (p>0.05) between patients with solid or hematologic tumors and during the follow-up. From the 6th until the 10th week of chemotherapeutic treatment alterations in swallowing function, in the mucous membrane (buccal mucosa and palate), in the labial mucosa, and in the gingiva occurred and were distributed differently between the two tumors groups (p<0.05). The main alterations were observed in patients with hematologic tumors. Conclusion: It was concluded that the oral changes during the chemotherapeutic treatment occurred especially in swallowing function, in the mucous membrane, in the labial mucosa and in the gingiva, and these alterations were found mainly in patients with hematologic tumors.

ABSTRACT

Abstract Natural products have emerged as a rich source of bioactive compounds for adjunctive treatments of many infectious and inflammatory conditions, including periodontitis. Among the monoterpenes with significant biological properties, there is the perillyl alcohol (POH), which can be found in several essential oils and has shown immunomodulatory properties in recent studies, which may be interesting in the treatment of non-neoplastic inflammatory disorders. Objective To determine the antibacterial and immune modulatory activities of the POH. Methodology The minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) of the POH for two significant Gram-negative periodontal pathogens were determined by macrodilution and subculture, respectively. Cell proliferation and cytotoxicity in RAW 264.7 macrophages were determined by Trypan Blue and mitochondrial enzymatic activity assay. The modulation of reactive oxygen species (ROS) was analyzed by flow cytometry and expression of TNF and arginase-1 by real-time PCR. Results The POH was effective against P. gingivalis (ATCC 33277) and F. nucleatum (ATCC 25586) with MIC= MBC=1600 μM. No cytotoxicity up to 100 µM was observed on macrophages. The cell proliferation was inhibited from 48 hours at 100 μM (p<0.05) and 250 μM (p<0.01). The POH increased ROS production at both 10 μM and 100 μM (p<0.05) in unstimulated cells. The PMA-induced ROS production was not affected by POH, whereas 100 μM significantly reduced lipopolysaccharide-induced (LPS-induced) ROS. The expression of TNF was not affected by POH in unstimulated cells or in cells polarized to M1 phenotype, whereas both concentrations of POH reduced (p<0.05) the expression of arginase-1 in M2-polarized macrophages. Conclusion The POH has antibacterial activity against periodontal pathogens and reduced proliferation of murine macrophages without significant cytotoxicity at concentrations up to 100 μM. In addition, the POH reduced the LPS-induced ROS and the expression of arginase-1 in M2-polarized macrophages.

ABSTRACT

Abstract Objective: To describe and compare how three dental schools from different countries (Australia, Brazil, and the USA) have managed experiences in dental education during the COVID-19 crisis. Material and Methods: It is a descriptive study reporting the experience that three distinct dental schools faced during the COVID-19 pandemic. They represent countries that adopted different measures to tackle the pandemic and were undergoing different stages of the disease. Results: After the WHO declared the COVID-19 pandemic, the Federal University of Paraíba suspended all on-site teaching, research, and service activities. For the return to teaching activities, the use of information and communications technology resources for distance learning was recommended. At the School of Dental Medicine (University of Pittsburgh), all research activities were suspended or, otherwise, could not be interrupted because of the employment of unique materials or supplies. When the pandemic started, Australia was one of the first countries to introduce strong regulations related to social distancing, travel restrictions, testing and tracking of infected patients. As such, the universities started to be closed from mid-March, cancelling all clinical and pre-clinical activities, maintaining online theoretical activities, such as seminars, lectures, and journal clubs. Conclusion: Numerous and critical difficulties have arisen as a result of the pandemic for individuals, communities and institutions that will have long-lasting effects. Our students face disruption to their education and career; our professional colleagues will be challenged rebuilding their practices, while staff at all Dental Schools are experiencing various hardships.

ABSTRACT

Este artigo propõe aproximações entre a Psicologia Social Comunitária, as pesquisas narrativas (auto)biográficas e a perspectiva decolonial. Reconhece-se, nesse sentido, que os efeitos da colonização latina seguem nutrindo lugares de enunciação muito distintos para sujeitos marcados pela diferença/desigualdade colonial na sociedade brasileira, o que tem produzido movimentos epistêmico-políticos decoloniais que interpelam o projeto de sujeito e sociedade construído a partir das lógicas coloniais. Dessa forma, é importante que possamos colaborar no endereçamento de que os sujeitos colonizados, a partir de suas narrativas, fazem à comunidade latina e brasileira em busca de elaboração denúncia e combate às desigualdades coloniais. É fundamental, portanto, que retomemos as alianças históricas que permitiram que os colonizados (re)inventassem outros mundos possíveis, rompendo com a posição subalterna, apenas, como lugar da vitimização. Devemos, assim, valorizar, eticamente, não sem (auto)críticas, os deslocamentos que as narrativas decoloniais proporcionam às narrativas comunitárias, historicamente, legitimadas como local de produção da transformação social.


This article builds approximations between Community Social Psychology, narrative (self) biographical research and the decolonial perspective. In this sense, it is recognized that the effects of the Latin colonization still harbor very distinct places of enunciation for subjects marked by the colonial difference / inequality in Brazilian society. What has produced decolonial epistemic-political movements which challenge the project of subject and society built from the colonial logics. Thus, it is important that we can collaborate in the addressing that the colonized subjects, from their narratives, make to the Latin and Brazilian community in search of elaboration, denunciation and combat to the colonial inequalities. It is therefore essential that we retake the historical alliances that allowed the colonized to (re)invent other possible worlds, breaking with the subaltern position, only, as a place of victimization. We must therefore ethically value, not without (self) criticism, the displacements that the decolonial narratives provide for historically legitimized community narratives as the place of production of social transformation.

ABSTRACT

Objective: To identify the profiles of patients with special needs attended at a Center for Dental Specialties. Material and Methods: This was a cross-sectional and quantitative study using an inductive approach, and a comparative and statistical procedure for analysis of the patients with special needs. Information concerning socioeconomic, medical and dental conditions was collected. The data were analyzed using IBM SPSS, adopting a significance level of 5%. Results: It was observed that 58.6% of the users were males, single (54.7%), in the age group from 19 to 59 years (41.1%), being 97.4% without schooling. The most frequent clinical diagnoses were: deviations in intelligence (18.4%), behavioral deviations (18.4%) and physical defects (17.9%). We observed for oral health the presence of gingivitis (33.0%), and healthy gums (47.8%); the presence of caries (64.9%), with restored teeth (28.5%), and edentulism (12.3%). Dental intervention procedures were initiated with emphasis on: fluoride applications (39.7%) and subgingival scraping (34.9%). Topical fluoride applications (p=0.010) and prophylaxis (p=0.010) were realized in patients without autism. Also, prophylaxis (p=0.007) was more frequently performed and gingival alterations were more often verified (p=0.020) in patients without Down's syndrome. Conclusion: The users of the patients with special needs dental service can be generally described as male, single, aged between 19 and 54 years, with the special conditions of intelligence and behavioral deviation.

ABSTRACT

Abstract Objective: To perform chemical analysis and to evaluate the anti-biofilm and hemolytic effect of the essential oil of Cymbopogon citratus. Material and Methods: Gaseous chromatography coupled to mass spectrometer was performed for chemical characterization of the essential oil. To verify the antimicrobial action, the Minimum Inhibitory Concentration (MIC), Minimum Bactericidal Concentration (MBC) and Minimum Fungicidal Concentration (MFC) were determined. From MIC, MBC and MFC data, concentrations were established to verify the anti-biofilm effect and for the hemolysis test on human erythrocytes. A multispecies biofilm was developed in vitro and mouthwash applications were simulated to determine the inhibition of biofilm formation or its removal. Results were analyzed through ANOVA statistical test, complemented by the Tukey test, considering a significance level of 5% Results: The major component of the essential oil is citral. MIC verified for Streptococcus mutans was 1mg / mL, while for Candida albicans, it was 125 μg/mL, presenting microbicidal effect for both microorganisms tested. The essential oil was able to inhibit biofilm formation (p<0.001), presenting non-toxic hemolysis percentage in concentration below 500 μg/mL Conclusion: The essential oil of Cymbopogon citratus is antimicrobial, antibiofilm and non-toxic to human erythrocytes, representing a natural product with potential for use in Dentistry.

ABSTRACT

ABSTRACT Purpose: to evaluate the methodological quality of clinical trials published in Brazilian journals. Methods: four trained independent researchers conducted a systematic literature search of all Brazilian speech therapy-related journals over the last ten years, whether the journals were active or inactive. All journal volumes published during that period were selected, and each researcher conducted an individual analysis to identify articles that focused primarily on orofacial motricity. The tools used were the Downs and Black Quality Checklist and the Jadad scale. Results: after the studies were selected and categorized, the final sample comprised six articles, all of which were classified as clinical trials. The observed methodological limitations included a lack of sample planning, randomization and blinding. Mean scores of 16.3 points on the Downs and Black Quality Checklist and 2.3 on the Jadad scale were obtained. Conclusion: the randomized controlled trials in the area of orofacial motricity are scarce in Brazilian literature, suggesting that studies in this area adopting this research design should be expanded and their quality should be improved to promote clinical practice based on scientific evidence.


RESUMO Objetivo: objetivou-se avaliar a qualidade metodológica dos ensaios clínicos publicados em periódicos brasileiros. Métodos: trata-se de uma pesquisa bibliográfica sistemática. Participaram quatro pesquisadores independentes treinados que realizaram um levantamento dos últimos 10 anos em todos os periódicos nacionais da área da Fonoaudiologia, ativos ou inativos. Para tanto, foram selecionados todos os volumes desse período de tempo e cada pesquisador realizou análise individual a fim de identificar estudos que tinham o principal objeto de estudo enquadrado na Motricidade Orofacial. Foram utilizados os seguintes instrumentos Downs and Black Quality Checklist e escala de Jadad. Resultados: após a seleção e categorização dos estudos, a amostra final desta pesquisa foi composta por 6 artigos classificados como ensaios clínicos. Dentre as limitações metodológicas observadas destacam-se a ausência de plano amostral, randomização e cegamento. Identificou-se uma média de 16,3 pontos para o Downs and Black Quality Checklist e 2,3 para escala de Jadad. Conclusão: conclui-se que a literatura brasileira é escassa de ensaios clínicos controlados randomizados na área de motricidade orofacial, sugerindo ampliação e qualificação das investigações que adotam esse delineamento de pesquisa, promovendo, dessa forma, uma prática clínica baseada em evidência científica.

ABSTRACT

O objetivo deste estudo foi compreender as percepções de estudantes de Odontologia de uma instituição pública de ensino superior sobre os estágios supervisionados em serviços públicos de saúde. Trata-se de uma pesquisa com abordagem qualitativa com o recurso de entrevistas semiestruturadas com 18 estudantes, selecionados por conveniência, matriculados do primeiro ao último ano do curso. As entrevistas, audiogravadas e transcritas, foram analisadas a partir da técnica de análise de conteúdo. Foram evidenciadas a aproximação com a população, a experiência profissional humanizada e o conhecimento construído pela vivência nos serviços, produzindo novas estratégias de atuação no Sistema Único de Saúde (SUS). As sugestões relacionaram-se à diversificação dos cenários de prática e a um melhor planejamento de atividades para o desenvolvimento de competências e habilidades. Por meio dos estágios, a formação volta-se para o SUS, que será novamente beneficiado com a inserção desses futuros profissionais na rede de serviços, com consequente melhoria do cuidado em saúde da população (AU).

ABSTRACT

Abstract The effect of fluoride agents on the retention of orthodontic brackets to enamel under erosive challenge is little investigated. Objective: The aim of this study was to evaluate the effect of titanium tetrafluoride (TiF4) and sodium fluoride (NaF) agents on the shear bond strength of brackets to enamel and on the enamel microhardness around brackets under erosive challenge. Methods: Brackets were bonded to bovine incisors. Five groups were formed according to fluoride application (n=10): TiF4 varnish, TiF4 solution, NaF varnish, NaF solution and control (without application). The specimens were submitted to erosive challenge (90 s cola drink/2h artificial saliva, 4x per day for 7 days). Solutions were applied before each erosive cycle and varnishes were applied once. Vickers Microhardness (VHN) was obtained before and after all cycles of erosion and the percentage of microhardness loss was calculated. Shear bond strength, adhesive remnant index and polarized light microscopy were conducted after erosion. The data were analyzed by ANOVA, Tukey, Kruskal-Wallis and Mann-Whitney U tests (α=0.05). Results: The %VHN had no statistically significant differences among the experimental groups. However, considering the comparisons of all groups with the control group, TiF4 varnish showed the highest protection from enamel demineralization (effect size of 2.94, while the effect size for the other groups was >2.4). The TiF4 varnish group had significantly higher shear bond strength compared to other groups. There was no difference among groups for adhesive remnant index. Polarized light microscopy showed higher demineralization depth for the control group. Conclusions: Application of NaF and TiF4 agents during mild erosive challenge minimized the enamel mineral loss around brackets, however only the experimental TiF4 varnish was able to prevent the reduction of shear bond strength of brackets to enamel.

ABSTRACT

Introduction: The incidence of lip, oral cavity and oropharynx cancer in Brazil is one of the highest worldwide. Objective: This study aimed to identify predictors for oral cancer in Brazil between 2010 and 2013. Method: Through a time series study in which 14,959 primary head and neck cancer diagnoses were evaluated. The variables of interest were gender, age, race, education level, family history of cancer, alcohol consumption, smoking, and previous cancer diagnosis. The outcome variable was divided into "oral cancer" and "cancer of other head and neck regions." The data were analysed by multiple binary logistic regression; α=5%. Result: The protective factor was: approximately 12 years of education (OR = 0.85). The risk factors were: being an ex-consumer (OR=1.19) or consumer (OR=1.11) of alcohol, tobacco use (OR=1.35) and a prior diagnosis of cancer that went untreated (OR=1.21). Conclusion: Was concluded that the oral cancer had the following predictors compared to other types of head and neck cancer during the same period: approximately 12 years of education (protective factor) and ex-consumer or consumer of alcohol, smoking and previous diagnosis of cancer that went untreated (risk factors).

ABSTRACT

Objective: To investigate the antifungal potential of A. colubrina, and its phytochemical characteristics, thermal profile and toxicity. Material and Methods: To assess potential antifungal activity, the technique of microdilution was used with the determination of the Minimum Inhibitory Concentration and Minimum Fungicidal Concentration, using standard species of Candida and recent clinical isolates of Candida albicans. Analyses of action of the extract were performed on the wall and cell morphology of C. albicans, of the interactive effect between the plant extract and nystatin on C. albicans through the checkerboard method, and of growth kinetics. The phytochemical screening was determined by spectrophotometry. The thermal profile was traced with the determination of thermogravimetric curves (TG) and differential scanning calorimetry (DSC). The toxicity was evaluated by the method of hemolysis. Results: The extract of A. colubrina showed a fungistatic potential against all bacteria tested and it acted by modifying the cellular morphology of C. albicans. There was a synergism between nystatin and the plant extract (FIC=0.375), and 53.18% of total polyphenols were determined. The TG curve showed the occurrence of three steps of thermal decomposition. None of the tested concentrations became the effective cytotoxic concentration. Conclusion: Further studies should be conducted to understand the efficacy and the mechanisms of action involved in the antifungal activity of the plant extract of A. colubrina in order to produce a new drug for the treatment of oral candidiasis.

ABSTRACT

Objective: To evaluate the anti-Candida effect of eugenol and its antimicrobial interaction with nystatin. Material and Methods: The antimicrobial potential was assessed by microdilution technique (M27A3 reference method), by determining the minimum inhibitory concentration (MIC) and the minimum fungicidal concentration (MFC) against C. albicans (ATCC 90028). The possible action of eugenol on the fungal cell wall was evaluated with the assistance of the osmotic protector sorbitol (0.8 M). The antimicrobial interaction with nystatin was assessed through the checkerboard method. All tests were performed in triplicate. Results: All groups showed reductions in PI and GBI values and improvements in oral health knowledge, but IG1 and IG2 showed statistically significant differences in these variables compared to CG. Conclusion: The eugenol has antifungal activity against C. albicans and its mechanism of action is probably not related to damage to the fungal cell wall. Association between eugenol and nystatin was not found to be an advantageous possibility for growth inhibition of C. albican.

ABSTRACT

Abstract School-age children are frequently at high risk for the onset of biofilm-dependent conditions, including dental caries and periodontal diseases. The objective of this study was to evaluate the clinical efficacy of a dentifrice containing Eugenia uniflora Linn. (Surinam cherry) extract versus a triclosan-based comparator in treating gingivitis in children aged 10-12 years. The in vitro antibacterial potential of the dentifrice was tested against oral pathogens (Streptococcus mutans, Streptococcus oralis and Lactobacillus casei). Then a phase-II clinical trial was conducted with 50 subjects aged 10-12 years, with clinical signs of gingivitis. The subjects were randomly assigned to the experimental group (n=25) and control group (n=25), in which participants used the experimental dentifrice and a triclosan-based fluoridated dentifrice (Colgate Total 12(r)), respectively. Clinical examinations assessed the presence of gingivitis (primary outcome) and biofilm accumulation (secondary outcome) using the Gingival-Bleeding Index (GBI) and Simplified Oral Hygiene Index (OHI-S), respectively, at baseline and after seven days of tooth brushing 3x/day. The data were analyzed using paired and unpaired t-test (GBI) and Wilcoxon and Mann-Whitney (OHI-S), with p≤0.05. The experimental dentifrice showed efficient antibacterial activity in vitro. In the clinical trial, a significant reduction in gingival bleeding was observed in both experimental and control groups (p<0.0001), with no statistical difference between them (p=0.178), although a small size effect was observed. Biofilm accumulation was only reduced in the control group (p=0.0039). In conclusion, E. uniflora dentifrice showed anti-gingivitis properties in children aged 10-12 years. Thus, it may be a potentially efficient and safe product to be used alternatively in preventive dental practice.


Resumo Crianças em idade escolar apresentam, com frequência, alto risco para o desenvolvimento de doenças biofilme-dependentes, incluindo cárie e doenças periodontais. Este estudo investigou a eficácia clínica de um dentifrício contendo o extrato de Eugenia uniflora Linn. (pitanga) comparado a um dentifrício com triclosan no combate à gengivite em crianças de 10 a 12 anos. Foi avaliado o potencial antibacteriano in vitro do dentifrício sobre microorganismos da cavidade oral (S. mutans S. oralis and L. casei) e realizado um estudo clínico fase II incluindo 50 sujeitos, com sinais clínicos de gengivite, divididos aleatoriamente em dois grupos: Experimental - 25 sujeitos usaram o dentifrício contendo extrato de pitanga; e Controle - 25 sujeitos que usaram um dentifrício fluoretado contendo triclosan (Colgate Total 12(r)). Na baseline e após sete dias consecutivos de escovação, foi realizado o exame clínico para diagnóstico de gengivite (desfecho primário) e acúmulo de biofilme (desfecho secundário), utilizando o Índice de Sangramento Gengival (ISG) e Índice de Higiene Oral Simplificado (IHO-S). Os dados foram analisados utilizando o teste t pareado e não pareado (ISG) e teste de Wilcoxon e Mann-Whitney (IHO-S), com nível de significância de p≤0,05. Observou-se uma efetiva atividade antibacteriana do dentifrício experimental. No estudo clínico, observou-se redução de sangramento gengival em ambos os grupos experimental e controle (p<0,0001), não havendo diferença entre eles (p 0,178), embora com uma pequena magnitude de efeito. Apenas o grupo controle reduziu significantemente o acúmulo de biofilme (p=0,0039). Concluiu-se que o dentifrício experimental de E. uniflora mostrou-se eficaz na redução de gengivite em crianças de 10 a 12 anos. Assim, este dentifrício apresenta potencial para ser utilizado de forma eficaz e segura em odontologia preventiva.
