ABSTRACT

Apandemia de COVID-19impôs ainterrupção deatividades presenciais coletivaseos profissionais de saúde foram os mais afetados, por estarem na linha de frente no combate desta doença. Medidas de biossegurança tiveram que ser redobradas para evitar a propagação do vírus e assim ajudar a controlar apandemia. Procedimentos que geram aerossóis na Odontologia foram evitados, pois é de conhecimento que um dos meios de transmissão é a saliva. Alguns Equipamentos de Proteção Individual(EPs) foram adicionados para garantir a proteção, e protocolos de desinfecção do ambiente foram modificados. O objetivo deste estudo foi avaliar o grau de conhecimento sobre biossegurança entre estudantes da área da saúde. Foiaplicado um questionário eletrônicopara a comunidade relacionada aos cursos da área da saúde na cidade de Curitiba/PR. Cento e cinquenta e novealunos responderam ao questionário, sendo 107 (67,3%) estudantesdaOdontologia, 28 (17,6%) da Medicina, 17 (10,7%) da Biomedicina e 7 (4,4%) daEnfermagem. Entre os participantes, 63,55% dos alunos de Odontologia, 100% de Medicina, 64,71% de Biomedicina e 85,71% de Enfermagem acreditam que os alunos da graduação não estão preparados para fazer atendimentos de urgência em pacientes com COVID-19. Apesar de toda a orientação sobre biossegurança, os alunos da área da saúde ainda devem desenvolver habilidades quanto aoscorretos procedimentos para atendimento de pacientes portadores ou não de doenças transmissíveis (AU).


Because of the COVID-19 pandemic, people all over the world had to interrupt their face-to-face interactions. Health professionals were most affected, as they were at the forefront of combating this disease. Biosecurity measures had to be re-doubled to prevent the spread of the virus and thus help control the pandemic. Procedures in dentistry that generated aerosols were avoided, as saliva is one of the means ofCOVID-19transmission. Complementary Personal Protective Equipment (PPE) was required to ensure protection, and environmental disinfection protocols had been modified. Thus, to assess the level of knowledge about biosafety and these new changes, particularly regarding COVID-19, a questionnaire was published for the community related to health courses in the city of Curitiba (PR, Brazil). This study included 159 students (dentistry, 107 (67.3%); medicine, 28 (17.6%); biomedicine, 17 (10.7%); and nursing, seven (4.4%)). Approximately 63.55% of dentistry, 100% of medicine, 64.71% of biomedical, and 85.71% of nursing students believe that undergraduate students are unprepared to provide urgent care to COVID-19 patients. Despite all the guidance on biosafety, students in healthcaremust still develop skills incorrect procedures for caring forpatients with or without communicable diseases (AU).

ABSTRACT

This study aimed to evaluate smartphone addiction, sleep quality, quality of life and depression among dental students before and during the first wave COVID-19 pandemic lockdown and explore how smartphone addiction influences the other variables. 57 dental students answered the smartphone addiction inventory, Pittsburg sleep quality index, WHOQOL-bref and research diagnosis criteria for temporomandibular disorders axis II questionnaires before and during lockdown. Statistical analysis was conducted using Wilcoxon test, Mann-Whitney U test, Spearman tests and linear regression models considering the smartphone addiction inventory total score as the independent variable. The high mean scores on smartphone addiction on both times are remarkable. The smartphoneaddictionprevalence was also high on both times (68.66% and 71.92% respectively). Overall sleep quality improved. However, there was no significant change on overall smartphone addiction, quality of life and depression grade during lockdown. Tolerance using smartphones increased during lockdown, especially for women. Smartphone addiction showed negative correlation to quality of life and positive correlation to depression, subjective sleep quality and sleep medication use. Smartphone addiction was apredictor to total WHOQOL-bref score, all WHOQOL-bref domains, sleep medication use and to depression on both times, before and during lockdown. Smartphone addiction was directly affecting quality of life. Despite the growing smartphone use among university students due to the pandemic restrictions, this study showed that the overall smartphone addiction, quality of life and depression grade were not influenced by the lockdown restrictions. However, it was observed an improvement on sleep quality during this period among dental students (AU).


O objetivo deste estudo foi avaliar o vício emsmartphones, qualidade de vida, qualidade de sono e depressão em estudantes de odontologia antes e durante a quarentena daprimeira onda da pandemia por COVID-19. 57 estudantes de odontologia responderam nos dois tempos os questionários validados:smartphone addiction inventory, índice de qualidade de sono de Pittsburg, WHOQOL-bref e critérios para diagnóstico em pesquisa dasdisfunções temporomandibulares eixo II. Foram realizados os testes estatísticos: Wilcoxon, Mann-Whitney U, Spearman e regressões lineares considerando o total do smartphone addiction inventorycomo variável independente. A prevalência de vício em smartphonesfoi elevada nos dois tempos (68.66% e 71.92% respectivamente). Durante a quarentena a qualidade de sono melhorou e não houve diferença estatisticamente significativa no vício em smartphones, qualidade de vida nem depressão. A tolerância no uso dossmartphonesaumentou, especialmente entre as mulheres. O vício em smartphonesapresentou correlação negativa com qualidade de vida e positiva com a depressão, qualidade subjetiva do sono e necessidade de medicação hipnótica. O vício em smartphonesfoi preditor para todos os domínios do WHOQOL-bref e seu escore total, para o uso de medicação e depressão em ambos os tempos. O vício em smartphonesfoi muito elevado nos dois tempos afetando a qualidade de vida dos estudantes. Apesar do aumento do uso desmartphonesem virtude das restrições impostas pela pandemia, esse estudo mostrou que o vício em smartphones, qualidade de vida e depressão não foram influenciados pela quarentena. Entretanto, foi observada melhora na qualidade de sono durante esse período (AU).

ABSTRACT

The need for new teaching-learning strategies stems from the great change society is going through. The so-called digital natives are part of a generation that lives in a hyperactive rhythm making it increasingly difficult to adapt to traditional classrooms. In Dentistry Courses, new strategies and pedagogical tools have been used, suchas active learning methodologies. In this context, the Discipline of Histology of the Dentistry Course has been proposing the use of some innovative pedagogical strategies. This work will present the experience with team-based learning (TBL), which articulates individual (iRAT) and group activities (gRAT), stimulates the application of concepts and can articulate with other methodologies such as flipped classroom, case study and problematization. This study alsoanalysedstudents' performance in iRAT and gRAT with the application of TBLand discussed the results achieved. Itwas conducted by analysingthe scoresof 240 first-year students of the Histology course in 2016, 2017 and 2018. Student scores, individually and in groups, were statistically analysedby the paired student t-test. Comparisons were made between the iRAT and gRAT activities about gender and the full-time and night classes by the one-way ANOVA and Kruskal-Wallis test. All students obtained higher group scores when compared to individual test results (p <0.001). There was no significant difference between sexes and study period. Group performanceexceeds individual performance. From this, it can be inferred that TBL can be a good strategy to use in dentistry, as an interaction between students leads to higher performance and problem-solving capacity (AU).


A necessidade de novas estratégias de ensino-aprendizagem decorre da grande mudança pela qual a sociedade está passando. Os chamados nativos digitais fazem parte de uma geração que vive em um ritmo hiperativo tornando cada vez mais difícil a adaptação às salas de aula tradicionais. Nos cursos de Odontologia, novas estratégias e ferramentas pedagógicas têm sido utilizadas, como metodologias ativas de aprendizagem. Nesse contexto, a Disciplina de Histologia do Curso de Odontologia tem proposto a utilização de algumas estratégias pedagógicas inovadoras. Este trabalho apresentará a experiência com a aprendizagem baseada em equipe (TBL), que articula atividades individuais (iRAT) e em grupo (gRAT), estimula a aplicação de conceitos e pode se articular com outras metodologias como aula invertida, estudo de caso e problematização. Este estudo também analisou o desempenho dos alunos no iRAT egRAT com a aplicação da TBL e discutiu os resultados alcançados. Foi realizado por meio da análise das notas de 240 alunos do primeiro ano do curso de Histologia em 2016, 2017 e 2018. As notas dos alunos, individualmente e em grupos, foram analisadas estatisticamente por meio do teste t-student pareado. As comparações foram feitas entre as atividades iRAT e gRAT sobre gênero e as aulas em período integral e noturno pelo teste ANOVA one waye teste de Kruskal-Wallis. Todos os alunos obtiveram pontuações mais altas do grupo quando comparados aos resultados dos testes individuais (p <0,001). Não houve diferença significativa entre os sexos e o período de estudo. O desempenho do grupo excede o desempenho individual. A partir disso, pode-se inferirque o TBL pode ser uma boa estratégia para uso em odontologia, pois uma interação entre os alunos leva a um maior desempenho e capacidade de resolução de problemas (AU).

ABSTRACT

The aim of the study was to assess knowledge of HIV/AIDS and the clinical and sexual practices of dental students. This was a cross-sectional study in which a self-administered questionnaire about age, gender, and dental program term; knowledge of HIV/AIDStransmission and prevention; use of personal protective equipment; prevention and occurrence of accidental exposure to biological material; post-exposure conduct; and sexual behavior was answered by dental students (n = 148, answer rate of 91.9%). Descriptive and inferential statistical analyses (chi-square and Fisher's exact tests) were performed, at a significance level of 5%. Students correctly recognized the routes of HIV transmission, including "blood" (100%), "sexual.3%). Regarding frequency of condom use during sexual intercourse, 37% of dental students said "always," 55.5% "sometimes" and 7.6% "never". Regarding clinical practices, 99.3% of dental students said they used personal protective equipment, 28.4% had intercourse" (99.3%), "vertical transmission" (58.1%) and "sharing contaminated material" (94.6%), and ways of prevention, including "condom use" (100%) and "not sharing needles and syringes" (99suffered percutaneous injuries, the needle was the most cited exposure agent (32.5%) and in most cases (54.8%), no providences were taken after the accident. In conclusion, the students had good knowledge of HIV / AIDS and appropriate preventive attitudes in clinical care and handling of sharp instruments; however, they still need to be motivated with regard to condom use and oriented about care after accidental exposure to biological material (AU).


O objetivo do estudo foi avaliar o conhecimento de HIV/AIDS e as práticas clínicas e sexuais de estudantes de Odontologia. Este foi um estudo transversal, no qual um questionário autoadministrado abordando: idade, gênero, período do curso; conhecimento sobre transmissão e prevenção de HIV/AIDS; uso de equipamentos de proteção individual; prevenção e ocorrência de exposição acidental a material biológico; conduta pós-exposição e comportamento sexual foi respondido por alunos de Odontologia (n = 148, taxa deresposta de 91.9%). Foram realizadas análises estatísticas descritiva e inferencial (testes qui-quadrado e exato de Fisher), comnível de significância de 5%. Os estudantes reconheceram corretamente as rotas de transmissão de HIV, incluindo "sangue" (100%), "relação sexual" (99,3%), "transmissão vertical" (58,1%) e "compartilhamento de material contaminado" (94,6%) e os meios de prevenção, incluindo "uso de preservativo" (100%) e "não compartilhar agulhas e seringas" (99,3%). Quanto à frequência do uso de preservativo nas relações sexuais, 37% dos estudantes responderam "sempre", 55,5% "às vezes" e 7,6% "nunca". Com relação a práticas clínicas, 99,3% dos estudantes de Odontologia afirmaram utilizar equipamentos de proteção individual, 28,4% já sofreram acidente perfurocortante, sendo agulha o agente de exposição mais citado (32,5%) e na maioria dos casos (54,8%) nenhuma medida foi tomada após o acidente. Em conclusão, os estudantes exibiram bom conhecimento acerca de HIV/AIDS e atitudes preventivas adequadasno atendimento clínico e manejo de instrumentais perfurocortantes, entretanto ainda precisam ser motivados quanto ao uso de preservativo e orientados sobre os cuidados pós-exposição acidental a material biológico (AU).

ABSTRACT

This study aimed to verify the extent to which the levels of quality of life are related to and influence suicide risk indices. A descriptive, correlational, quantitative research was performed. A non-probabilistic sample was used which was composed of 11,863 Brazilian participants all over 18 years old, who responded to the Risk Assessment Suicide Scale (RASS) and the World Health Organization Quality of Life BREF Instrument (WHOQOL-BREF), and whose data were analyzed by using descriptive statistics, the Spearman correlation and multiple linear regression using the Statistical Package for Social Sciences (SPSS). The results identify negative, moderate and significant correlations between the constructs, and that the domains of quality of life influence 47.8% of the variations in the suicide risk indices, confirming that the psychological domain is the most relevant within the explanatory model created. The conclusion is that there is a the need for public policies to improve the quality of life and prevent suicide (AU).

ABSTRACT

Introdução:O carcinoma de células escamosas de cavidade oral e orofaringe é uma neoplasia epitelial maligna comum, respondendo pela maioria dos casos de tumores de cabeça e pescoço. Ele está relacionado a hábitos comportamentais, como tabagismo e etilismo de longa duração, e à infecção pelo Papilomavírus humano. Objetivos:Esse estudo objetivou descrever o perfil epidemiológico dos pacientes diagnosticados com essa neoplasia na Liga Mossoroense de Estudos e Combate ao Câncer. Metodologia: Foi realizado um estudo observacional com delineamento transversal a partir de dados presentes nos prontuários clínicos e laudos anatomopatológicos e no Sistema de Informações sobre Mortalidade no período entre 2006 a 2018. Os dados foram analisados a partir do Software R, utilizandoo teste de Wilcoxon-Mann-Whitney para as análises inferenciais e o método de Kaplan-Meier para análise da sobrevida. Resultados:225 prontuários foram analisados, sendo 70,22% de homens, 65,33% na faixa etária entre 46-70 anos e cor branca (51,57%). Destes, 25,78% eram tabagistas e 39,11% tabagistas e etilistas. O principal tratamento identificado foi a associação de cirurgia, quimioterapia e radioterapia. Observou-se que 49,10% dos óbitos foram em decorrência dessa neoplasia. O principal estádio patológico encontrado foi o quatro A (34,22%). Foi identificada maior sobrevida nos pacientes acima de 70 anos, cujo tratamento foi exclusivamente cirúrgico. Menor sobrevida foi identificada em indivíduos que tinham associação de hábitos (etilismo e tabagismo). Conclusões:Nossos resultados sugerem que a evolução à óbito foi o principal desfecho clínico e, isso pode estar relacionado aos hábitos comportamentais que influenciam diretamente o curso e prognóstico da doença. Ademais, destaca-se a importância do diagnóstico precoce a fim de reduzir óbitos e melhorar a qualidade de vida dos indivíduos, assim como a necessidade de implementar políticas educativas sobre os principais fatores de risco associados ao desenvolvimento dessa neoplasia (AU).


Introduction: Squamous cell carcinoma of the oral cavity and oropharynx is a common malignant epithelial neoplasm, accounting for most cases of head and neck tumors. It is related to behavioral habits, such as long-standing smoking and alcoholism, as well as to the human Papillomavirus infection. Objectives: This study aimed at describing the epidemiological profile of the patients diagnosed with this neoplasm in the Mossoró League for Studying and Combating Cancer. Methodology:An observational study with a cross-sectional design was carried out based on data present in the medical records and anatomopathological reports and in the Mortality Information System during the 2006-2018 period. The data were analyzed using the R Software, resorting to the Wilcoxon-Mann-Whitneytest for the inferential analyses and to the Kaplan-Meier method for survival analysis. Results: 225 medical records were analyzed: 70.22% belonging to men, 65.33% aged between 46 and 70 years old and white-skinned (51.57%). Of these, 25.78% were smokers and 39.11% were smokers and alcoholics. The main treatment identified was the association of surgery, chemotherapy and radiotherapy. It was observed that 49.10% of the deaths were due to this neoplasm. The main pathological stage found wasfour A(34.22%).Longer survival was identified in patients over 70 years of age, whose treatment was exclusively surgical. Shorter survival was identified in individuals who had associated habits (alcoholism and smoking). Conclusions:Our results suggest that evolution to death was the main clinical outcome; this can be related to the behavioral habits that exert a direct influence on the course and prognosis of the disease. Furthermore, the importance of early diagnosis is highlighted in order to reduce the number of deaths and improve the individuals' quality of life, as well as the need to implement educational policies on the main risk factors associated with the development of this neoplasm (AU).

ABSTRACT

Abstract Objective: To evaluate the effectiveness of chewing gums containing CPP-ACP in remineralisation of demineralised enamel around orthodontic brackets. Material and Methods: Enamel blocks from 120 bovine incisors were used. The blocks were flattened and polished, followed by the development of incipient subsurface caries. The blocks have been subjected to a baseline microhardness analysis. Orthodontic brackets were bonded to the exposed area of the blocks, reserving an area for hardness analysis. An in situ crossover (three-way crossover phases of 21 days with an interval of one week between them), controlled, randomised and blind experimental model was used, with the participation of 12 volunteers divided into groups: G1 - negative control group, without chewing gum; G2 - conventional sugar-free chewing gum, without CPP-ACP (placebo); and G3 - sugar-free chewing gum with CPP-ACP. The following parameters were analysed: superficial linear (Ra), volumetric roughness (Sa), and superficial structural loss, which was indicated by Gap measurement (difference between the healthy and treated area). Statistical tests used were the Friedman, Wilcoxon and Shapiro-Wilk, Kruskal Wallis' nonparametric tests and ANOVA. Results: There was a significant reduction in enamel microhardness after demineralisation in all the groups (p<0.05). This deleterious effect was attenuated in the three groups after the final evaluation, although there were no statistical differences (p<0.05); however, the final values did not return to the baseline values (p<0.05). Conclusion: Chewing gum containing CPP-ACP did not promote in situ remineralisation of demineralised enamel around orthodontic brackets.

ABSTRACT

Abstract Objective: To evaluate the efficacy of silver diamine fluoride (SDF) in arresting dentin caries lesions when applied under different concentrations and times. Material and Methods: Forty-two bovine blocks were selected and fixed in 24-well plates. Each well received a mixed bacterial inoculum added to the culture medium with 5% sucrose. The plates were incubated in microaerophilia (7 days) for caries formation, confirmed by micro-CT (M1). SDF was applied over the carious lesions for different times and concentrations (n=6): SDF 30% - immediate removal, 1 minute and 3 minutes; SDF 38%, - immediate removal, 1 minute and 3 minutes. The group without treatment was the control. Then, the samples were again scanned by micro-CT (M2) and submitted to a second cariogenic challenge for 21 days. Then, a final scan was performed (M3). Results: Mean pH at the culture medium and lesion depth were compared using Kruskal-Wallis and Wilcoxon tests. 38% SDF showed the lowest metabolic activity of the biofilm. All 38% groups and 30% 1 and 3 minutes did not show an increase in mean lesion depth comparing M3 with M1. However, only 30% 3 minutes and 38% 1 and 3 minutes showed a significant reduction of lesion depth. Conclusion: The minimum application time of 30% SDF to arrest dentin caries lesion was 1 minute, while 38% SDF arrested with application and immediate removal.

ABSTRACT

Abstract Item Response Theory represents one of the major advances in the field of developing valid and reliable measures in psychology. Among the main models used in this perspective are the Rasch model and the logistic models. These parametric models, however, are not suitable for all applications in psychology, since a substantial number of databases in psychology do not satisfy the assumptions of these models: unidimensionality; latent monotonicity; local independence; and, for some models, non-intersecting functions. Given this framework, the objective of this study was to present the theoretical and practical foundations of Mokken Scale Analysis (MSA). We present some historical issues involving the development of MSA, in addition to the main characteristics and assumptions of the two models used in this perspective. After exemplifying a MSA application, limitations and final considerations are presented, supporting the decision-making process for researchers who come to use MSA.


Resumo A Teoria de Resposta ao Item representa um dos principais avanços para a construção de medidas válidas e confiáveis em psicologia. Entre os principais modelos utilizados nessa perspectiva estão o modelo de Rasch e os modelos logísticos. Esses modelos paramétricos, no entanto, não podem ser utilizados em todas as aplicações em psicologia, uma vez que um número substancial dos bancos de dados em psicologia não satisfaz os pressupostos desses modelos: unidimensionalidade; monotonicidade latente; independência local; e, para alguns modelos, não-interseção de funções. Dessa forma, o objetivo deste estudo foi apresentar os fundamentos teóricos e práticos da Análise de Escala de Mokken (AEM). São apresentadas questões históricas envolvendo o desenvolvimento da AEM, além das principais características e pressupostos dos dois modelos usados nessa perspectiva. Após exemplificação de uma AEM, limitações e considerações finais são apresentadas, apoiando o processo de tomada decisão para pesquisadores que venham a usar a AEM.

ABSTRACT

Abstract Research on the constitution of subjectivity continues to be a relevant topic for Psychology. This study aimed to analyze the relevance of exploring autobiographical narratives as a methodological resource for understanding this process. Anchored in the premises of historical-cultural psychology in dialogue with other theoretical perspectives, the defended thesis is that, through this theoretical-methodological alternative, it is possible to investigate the different interrelated domains in the processes of constitution of subjectivities, such as the works of memory, language and the dynamic character that they establish with historical and cultural circumstances. The text comprises four parts: the first explores the challenges involved in researching subjectivity; the second, the contributions of Vygotskian psychology to the understanding of the phenomenon; the third, the fecundity of narratives as methodological resources for the study of subjectivation processes. In the last topic, considerations are made about some results of research carried out from school memories.


Resumo A pesquisa sobre a constituição da subjetividade continua sendo um tema relevante para a Psicologia. Este estudo objetivou analisar a pertinência da exploração das narrativas autobiográficas como recurso metodológico para a compreeensão de tal processo. A tese defendida, ancorada nas premissas da psicologia histórico-cultural em diálogo com outras perspectivas teóricas, é que, por meio dessa alternativa teórico-metodológica, é possível investigar os diferentes domínios inter-relacionados nos processos de constituição das subjetividades, como os trabalhos da memória, da linguagem e o caráter dinâmico que estabelecem com as circunstâncias históricas e culturais. Quatro partes compõem o texto: a primeira explora os desafios envolvidos na pesquisa sobre a subjetividade; a segunda, as contribuições da psicologia vygotskiana para a compreensão do fenômeno; a terceira, a fecundidade das narrativas como recursos metodológicos para o estudo dos processos de subjetivação; no último tópico, são feitas considerações sobre alguns resultados de pesquisas realizadas a partir das memórias escolares.


Resumen La investigación sobre la constitución de la subjetividad continúa siendo un tema relevante para la Psicología.

ABSTRACT

Abstract Aim: To verify the effects of a multimodal exercise program on balance and motor functions, and the differences by sex, in people with Parkinson's disease (PD). Methods: The intervention study, was composed of 16 people with PD, that were assessed before and after 16 weeks of interventions with the multimodal exercise program. The effects were analyzed generally and by sex, using the Wilcoxon Test. The significance level was established at 5%. Results: Overall, there was an improvement in the strength of the lower limbs (LL) (p = 0.035) and upper limbs (UL) (p = 0.009), functional mobility (p = 0.003), gait (p = 0.050), balance (p = 0.001) and in motor scores of UPDRS III (p = 0.005), which categorize motor symptoms of the disease. In regards to sex, women affected muscle strength (p = 0.044) and flexibility of LL (p = 0.028), gait (p = 0.018), and motor aspects of the UPDRS III (p = 0.042). The men presented effects in muscle strength of the UL (p = 0.042). Women and men had a significant increase in functional mobility (p = 0.046 and p = 0.027, respectively) and in balance (p = 0.012 and p = 0.042, respectively). There was no significant difference for both sexes, in body mass and the reach behind the backtest. Conclusion: the multimodal exercise program contributed to the improvement in motor function and balance in men and women with PD. Nevertheless, the effects were more significant in women. The comprehension of the differences between men and women grants us a more directional and efficient approach to their treatment.

ABSTRACT

Abstract Objective: To evaluate the barriers to access and oral health care faced by children and adolescents with Cerebral Palsy (CP) according to their motor impairment through the perception of caregivers. Material and Methods: A case series study was carried out at three health institutions in Pernambuco, Brazil. The study sample consisted of 94 caregivers of 5-to-18-year-old patients with CP, according to GMFCS (The Gross Motor Function Classification System). Data were collected using a semi-structured form to evaluate the barriers to access and analyzed statistically by the chi-square and Fisher exact tests, adopting a 5% level of significance. In addition, binary logistic regression was performed to determine the weight of the variables in explaining the outcome variable. Results: There were major difficulties involving transportation (p=0.04) and structural accessibility to dental services (p<0.01) among children and adolescents with severe CP. In addition, the more severe the CP, the greater the difficulty of accessibility (OR=4.09,) and the lower the income (OR=8.80), the greater the motor impairment. Conclusion: Despite the availability of access to dental services, low-income families have more severe CP patients, contributing to the daily difficulties already faced by them in oral health care.

ABSTRACT

Abstract Objective: To analyze patients' pain perception requiring endodontic treatment referred to a Dental Specialties Center. Material and Methods: Data was collected through a self-administered questionnaire for patients about their experience of pain and another for endodontists about the treatment performed. The results were analyzed descriptively using Pearson's Chi-square test and Fisher's Exact test, with Bonferroni correction (p≤0.05). Results: The median age of the patients was 39 years, and 71.1% were female. The median waiting time for treatment was five months. Pain was reported by 75.2% of patients, occurred more than one month earlier (63.6%), with moderate/severe intensity (66.9%), and most patients sought emergency treatment more than once (79.1%). In addition, pain was associated with sex (female; p=0.008); moderate/severe intensity (p<0.001); the number of times that patient had to go to the dentist because of the tooth treatment (twice or more; p=0.002); and type of tooth treated (posterior tooth; p=0.002). Conclusion: Severe pain episodes resulted in a repeated search for emergency services, which may overload the primary care service, especially if the waiting time for endodontic treatment is long.

ABSTRACT

Abstract Objective: To assess the influence of the COVID-19 pandemic on levels of anxiety, stress, and orofacial pain in individuals with and without TMD. Material and Methods: In this cross-sectional study, the participants were divided into two groups (n=10, each) experimental group (EG) TMD patients and control group (CG), without TMD. The presence of TMD was confirmed using the RDC/TMD. The Beck Anxiety Scale (BAI), Perceived Stress Scale (PSS), and Oral Analog Scale were used for assessment. The Beck Anxiety Scale is composed of 21 multiple-choice questions describing symptoms of anxiety, while the PSS is a measure that evaluates life situations as stressful. An Oral Analogue Scale was applied to each individual to quantify orofacial pain, with 0 (zero) without pain and 10 (ten) being the worst pain ever felt. The comparison between groups was performed using the Mann-Whitney test. Logistic regression was used to verify TMD dependence in relation to BAI and PSS-10. Quantitative variables were correlated with each other by Pearson's correlation coefficient. The level of significance considered for all tests was 5%. Results: The association was statistically significant (p≤0.05) for BAI and PSS with a TMD. Conclusion: Although the COVID 19 pandemic has had a psychological impact on the general population, patients with TMD have higher levels of anxiety and stress than the control group.

ABSTRACT

Abstract Objective: To compare the Oncostatin M (OSM) concentrations in tissues of patients with chronic periodontitis with and without diabetes. Material and Methods: Sixty-four subjects visiting the dental outpatient department were categorized as "healthy" (Group 1), "periodontitis" (Group 2), and "diabetes with periodontitis" (Group 3) groups. The clinical oral examination included assessment of plaque, gingivitis, probing depth, clinical attachment level. Blood glucose was assessed for group 3 patients. OSM concentration in the tissues was assessed using ELISA in all groups. Results: The mean OSM was 0.02 ± 0.04 pg/mg in the healthy group, 0.12 ± 0.09 pg/mg in the chronic periodontitis group and 0.13 ± 0.10 pg/mg in the diabetes-periodontitis group. A significantly higher mean OSM was seen in Group 2 and Group 3 than Group 1. The amount of OSM positively correlated with probing depth and clinical attachment level. Conclusion: Periodontal disease causes a rise in Oncostatin M, independent of the diabetic status. Expression of OSM in the gingival tissues can serve as an inflammatory marker.

ABSTRACT

Abstract Objective: To analyze and compare changes of quality of life parameter among dental patients rehabilitated by the implant-supported overdentures with different attachment systems. Material and Methods: Forty-eight patients were recruited as a study cohort. The implant placement procedure was based on the results obtained by CBCT scanning and individualized surgical templates manufactured for correct implant placement. Each individual received two k3Pro Implants (Sure Type with 4.0 or 4.5 mm in diameter) at the intraforaminal area due to standard protocol of implantation provided by the manufacturer under local anesthesia. All patients were distributed between two groups based on the fact of using either Locator- or ball-attachments. Rank correlation was measured using Spearman correlation coefficient, while linear correlation was evaluated by Pearson correlation coefficient. Results: No statistically meaningful differences were noted regarding patients' distribution among groups considering age (p>0.05) and gender (p>0.05). Provided patient-level analysis demonstrated that increase of conventional full denture service time was positively correlated with escalation of OHIP-EDENT scores. The most prominent inter-correspondences were noted specifically between longevity of denture service and elevation of scores within "Functional limitation" (r=0.61; p<0.05), "Physical pain" (r=0.51; p<0.05) and "Physical disability" (r=0.57; p<0.05) subdomains. No statistically argumented regressions were noted between increase tendency of OHIP-EDENT scores and gender (p>0.05) or age (p>0.05) parameters. Conclusion: Significant improvements of quality of life measured with OHIP-EDENT were noted for both types of attachments compared to the pre-treatment situation independently of additionally provided surface electromyography-based alignment.

ABSTRACT

Abstract Objective: To evaluate the effectiveness of Antimicrobial Photodynamic Therapy (aPDT), associated with scaling and root planing in the non-surgical periodontal treatment of individuals with Down Syndrome. Material and Methods: A controlled, randomized, split-mouth study was conducted. A total of 8 participants diagnosed with Down Syndrome aged 17-38 years of both sexes with clinical periodontitis were included in the study. Participants were treated at least three times: at the baseline, Plaque Index (PI), Bleeding on Probing (BOP), and Probing Pocket Depth (PPD) were obtained. After one week, conventional scaling and root planing were performed, and two quadrants were randomly selected for aPDT application. The reassessment was obtained one month after the aPDT application. The significance level was set at 5%. Analyses were performed considering a 95% confidence interval. Results: In the intergroup evaluation, no statistically significant differences were observed (p>0.05). In the intragroup evaluation, no statistically significant variations were observed in relation to the PI (p>0.05) and PPD (p>0.05); however, a statistically significant reduction in the BOP was observed between the test group (p=0.013) and control group (p=0.015). Conclusion: The use of aPDT as adjuvant therapy did not promote additional benefits in decreasing PI and PPD after 1 month of treatment. However, a significant reduction in the BOP was observed in the intragroup evaluation.

ABSTRACT

ABSTRACT Objective To determine the level of knowledge of dentistry students regarding the COVID-19 outbreak and to evaluate whether the risk factors of the outbreak cause depression. Material and Methods This study was conducted with 516 dentistry students (3rd, 4th and 5th grades) who started clinical practice in their education. The first part of the questionnaires applied to the students includes questions about demographic information, while the second part contains questions to determine their knowledge levels on the COVID-19 pandemic and protection against it. In the third section, Beck Depression Inventory (BDI) was used to examine depression symptoms. The data were analyzed by frequency analyses and Chi-squared tests via the IBM SPSS 22.0 software. Results Of the 516 students, 150 (29%) participants were in the 3rd, 212 (41%) were in the 4th and 154 (30%) were in the 5th grade. 355 (69%) students stated that their knowledge level about COVID-19 was high. 30.9% were conscious of the importance of using masks. 29.6% were aware of the importance of using gloves, 30.3% of not shaking hands. According to BDI scores, 37.1% of the participants seemed to experience moderate to severe and very severe depression. Conclusion It was observed that the students didn't have a sufficient level of knowledge about the factors affecting the spread of the pandemic. New stress factors such as COVID-19 may increase the incidence of depression.

ABSTRACT

Fundamento: O tempo de aceleração na artéria pulmonar (TAP) pode ser utilizado para avaliação da hipertensão pulmonar na análise da função diastólica do ventrículo esquerdo. Objetivo: Avaliar se existe correlação entre o valor do tempo de aceleração na artéria pulmonar e parâmetros da função diastólica do ventrículo esquerdo em indivíduos com função sistólica do ventrículo esquerdo preservada e de acordo com sexo, idade e fatores de risco cardiovasculares. Métodos: Estudo observacional, transversal. Foram selecionados 119 pacientes (59 mulheres; 49,6%). Os indivíduos foram submetidos ao ecocardiograma transtorácico incluindo os valores de tempo de aceleração na artéria pulmonar; ondas E e A e relação E/A ao Doppler espectral do influxo mitral; ondas e' septal, e' lateral e relação E/e' ao Doppler tecidual do anel mitral; pressão sistólica na artéria pulmonar e volume atrial esquerdo. Resultados: No sexo feminino, foi encontrada correlação positiva (coeficiente de correlação de Spearman) entre o valor do tempo de aceleração na artéria pulmonar e e' lateral (coeficiente de correlação de Spearman de 0,47; p=0,002), relação E/A (coeficiente de correlação de Spearman de 0,32; p=0,04) e e' septal (coeficiente de correlação de Spearman de 0,36; p=0,023) e uma correlação negativa entre o valor do tempo de aceleração na artéria pulmonar e pressão sistólica na artéria pulmonar (coeficiente de correlação de Spearman de -0,43; p=0,034). No sexo masculino, não foi encontrada correlação significativa. Foram encontrados menores valores de tempo de aceleração na artéria pulmonar em mulheres com hipertensão arterial sistêmica quando comparadas a mulheres sem hipertensão arterial sistêmica (0,13±0,03 segundos versus 0,16±0,03 segundos; p = 0,015). Conclusão: O presente estudo mostrou correlação significativa dos valores do TAP com alguns parâmetros da função diastólica do ventrículo esquerdo apenas no sexo feminino, sendo que mulheres hipertensas apresentaram menores valores de TAP.

Background: Pulmonary artery acceleration time (PAAT) can be used as a parameter in the evaluation of pulmonary hypertension and aids left ventricular diastolic function (LVDF) analyses. Objective: To assess whether there is a correlation between PAAT and LVDF parameters in individuals with a preserved left ventricular systolic function and by sex, age, and cardiovascular risk factors. Method: Observational cross-sectional study. One hundred nineteen patients were selected (59 women [49.6%]). The subjects underwent transthoracic echocardiography including measurements of PAAT, E and A waves and E/A ratio, e' septal and e' lateral waves and E/e' ratio, pulmonary artery systolic pressure (PASP), and left atrial volume. Results: In female patients, a positive correlation (Spearman's correlation coefficient ­ Spearman correlation coefficient [SCC]) was found between the PAAT value and the lateral e' (SCC, 0.47; p = 0.002), with the E/A ratio (SCC, 0.32; p = 0.04), and with septal e' (SCC, 0.36; p = 0.023), and a negative correlation between PAAT and PASP (SCC, -0.43; p = 0.034). In men, no correlation was found between PAAT. and any parameters. Lower PAAT values were found in women with systemic arterial hypertension (hypertension) than in women without hypertension (0.13 ± 0.03 s versus 0.16 ± 0.03 s; p = 0.015). Conclusion: The present study showed a significant correlation between PAAT and some LVDF parameters in female patients only. Hypertension was correlated with lower PAAT values in women. (AU)

ABSTRACT

Abstract Background: Fatigue is a disabling symptom in the spectrum of Parkinson's disease (PD), affecting from 30% to 70% of the persons. Even though it is a common symptom, with negative repercussions for PD individuals, its correlation with balance is not established. Aim: The aims of this study were to verify the correlation between fatigue and balance in individuals with PD and to compare balance in individuals with PD that presents low fatigue or high fatigue. Methods: This study included 37 individuals with PD, who were divided into two groups: low fatigue (n = 25) and high fatigue (n = 12). Fatigue was evaluated using the Parkinson's disease Fatigue Scale and a force platform was used to assess four balance tasks: bipedal, tandem with eyes open/closed, and tandem with the dual-task, in three parameters: (1) 95% confidence ellipse area of the center of pressure (COP) (2) mean velocity (3) root mean square of COP. To verify the correlation between fatigue and balance, the Spearman rank-order correlation coefficient was assessed. Comparison of medians between the groups was analyzed using the Mann-Whitney test. Results: There was no significant correlation between fatigue and balance. There was no difference between the groups with low and high fatigue. Conclusion: This study's findings, together with those reported in the literature, suggest there is no correlation between fatigue and balance, and even though individuals with PD report fatigue or experience situations of fatigue, they do not present greater posture instability than individuals with PD who do not report fatigue. Fatigue is a disabling symptom in the spectrum of Parkinson's disease (PD), affecting from
