ABSTRACT

In Brazil, bodily practices and physical activity (BPPA) have come a long way, with the implementa-tion of policies, actions and programs that have substantially contributed to public health. However, recent setbacks, in which political instability, scarcity and cuts in public spending predominate, show that more progress and consolidation in the National Health System (SUS) are still needed. Thus, the objective of this article is to demonstrate the aspects that must be considered for promoting BPPA in primary health care, discussing its complexity and multifactorial nature, aimed at health profession-als, especially in physical education. In conclusion, essential aspects were highlighted, ranging from the struggle to defend and advance public policies that encourage the promotion and consolidation of the BPPA, to theories that help understand the dimensions of human behavior


No Brasil, as práticas corporais e atividade física (PCAF) obtiveram avanços com a implementação de políticas, ações e programas que contribuíram substancialmente com a saúde pública. Entretanto, recen-tes retrocessos, em que a instabilidade política, escassez e cortes de gastos públicos predominam, evidenciam o quando as PCAF ainda precisam avançar e serem consolidadas no Sistema Único de Saúde. Assim, o objetivo desse ensaio é demonstrar os aspectos que devem ser considerados para a promoção das PCAF na Atenção Primária à Saúde, trazendo reflexões quanto a sua complexidade e multifatoriedade. Essa reflexão é direcionada aos profissionais de saúde, sobretudo aos profissionais de Educação Física. Em conclusão, foram ressaltados aspectos essenciais, que vão desde a luta pela defesa e avanço de políticas públicas que incentivem o fomento e consolidação das PCAF até a apropriação de teorias que ajudem a compreender a dimensão do comportamento humano

ABSTRACT

ABSTRACT This study evaluated the influence of resin cements and glass ionomers on tensile strength and types of failure of zirconia copings cemented on titanium base abutments. Forty-two samples were prepared, which were formed by a Cone Morse implant, a titanium abutment with the fixing screw, and a zirconia structure made using a CAD/CAM system. The samples (n = 42) were randomly distributed according to the cementing agent: resin-modified glass ionomer cement (RelyX Luting 2), self-adhesive resin cement (RelyX U200), and self-curing resin cement (Multilink N). After cementation of the copings, half of the samples from each group (n = 7) were randomly selected and subjected to thermocycling (5000 cycles). A tensile load test was performed on a universal testing machine until failure occurred (1 mm). In addition, the type of failure was analyzed using the two-way analysis of variance test and Tukey's post-hoc test (α = 0.05). Lower tensile load was observed for the glass ionomer cement (p < 0.001) regardless of the evaluation period. After thermocycling, a significant reduction in tensile load values was verified for both evaluated cements (p = 0.047). For the resin cements, failures were predominantly of the screw fracture type (82.1%) already with the use of glass ionomer cement, and 28.5% of the failures were of an adhesive type between the zirconia coping and the cement. Resin cements have better stability under tensile load compared to resin glass ionomers when cementing zirconia copings on titanium base abutments.


RESUMO Este estudo avaliou influência dos cimentos resinosos e a base de ionômero de vidro na resistência à tração e os tipos de falhas de copings de zircônia cimentados sobre pilares TiBase. Foram confeccionadas 42 amostras, sendo estas formadas por implante cone morse, pilar de titânio (TiBase) com o parafuso de fixação e uma estrutura de zircônia (coping de Zr) confeccionado através do sistema CAD/CAM. As amostras (n =42) foram aleatoriamente distribuídas de acordo com o agente de cimentação: (cimento de ionômero de vidro modificado por resina [RelyXTMLuting2]; cimento resinoso autoadesivo [RelyXTM U200] e cimento resinoso autopolimerizavel (Multilink® N). Após cimentação dos copings, metade das amostras de cada grupo (n = 7) foram aleatoriamente selecionadas e submetidas a termociclagem (5000 ciclos). O Teste de resistência a tração foi realizado em uma máquina de ensaio universal, até que ocorresse a falha (1 mm/min). Adicionalmente, o tipo de falha foi analizado. Os dados foram analisados pelo teste ANOVA two-way e post teste de Tukey's (α = 0.05). Menor média de resistência a tração foi observada para o cimento de ionômero de vidro (p < 0,001) independente do período de avaliação. Após a termociclagem, foi verificada uma redução significativa nos valores de resistênca a tração, para os cimentos avaliados (p=0,047). Para os cimentos resinosos, as falhas foram predominantemente do tipo fratura do parafuso (82,1%) já com o uso do cimento de ionômero de vidro, 28,5% das falhas foram de tipo adesiva entre o coping de Zr e o cimento. Cimentos resinosos apresentam melhor estabilidade na resistência a tração em comparação a ionmeros de vidro resinosos na cimentação de copings de zircônia sobre pilares TiBase.

ABSTRACT

Abstract Objective: To evaluate the main technical limitations of automated breast ultrasound and to determine the proportion of examinations excluded. Materials and Methods: We evaluated 440 automated breast ultrasound examinations performed, over a 12-month period, by technicians using an established protocol. Results: In five cases (1.1%), the examination was deemed unacceptable for diagnostic purposes, those examinations therefore being excluded. Conclusion: Automated breast ultrasound is expected to overcome some of the major limitations of conventional ultrasound in breast cancer screening. In Brazil, this new method can be accepted for inclusion in routine clinical practice only after its advantages have been validated in the national context.

ABSTRACT

O objetivo foi monitorar indicadores de saúde mental e a prática de exercícios de respiração e alongamento no contexto doméstico durante dois meses da pandemia COVID-19 entre mulheres participantes de dois grupos de atividade física de Unidades Básicas de Saúde. A amostra foi composta por 17 mulheres, que participaram de quatro contatos telefônicos. As variáveis foram a autopercepção de saúde, da ansiedade, da qualidade do sono e da concentração, além de dificuldades econômicas (falta do básico em casa no período) e a prática de exercícios de respiração e alongamento no domicílio, bem como as dificuldades para a realização destas. O teste de Friedman foi utilizado para verificar diferenças nas variáveis nos quatro momentos. Diferenças significativas na autopercepção da qualidade do sono (com piores resultados em T4) e na prática de exercícios (piores resultados em T1) foram observadas. Em três dos quatro momentos do monitoramento, pelo menos uma mulher referiu que havia faltado o básico para a sobrevivência. Onze mulheres citaram barreira(s) em pelo menos um dos momentos do estudo para a realização dos exercícios, sendo a mais citada: não saber realizar o exercício ou se sentir insegura realizando sozinha. Conclui-se que, considerando a necessidade de adequação dos serviços de saúde em função da pandemia, ações de monitoramento, combinadas com estratégias de escuta e aconselhamento, podem ser uma boa alternativa para o acompanhamento da saúde dos participantes dos grupos de atividade física


The objective was to monitor mental health indicators and the practice of breathing and stretching exercises in the domestic context during two months of the COVID-19 pandemic among women who were enrolled in two physical activity groups in Primary Health Care. The sample included 17 women, who participated in all telephone contacts at four moments. The variables were self-perceived health, anxiety, quality of sleep and concentration, in addition to economic difficulties (lack of basics at home in the period), breathing and stretching exercises at home, and possible barriers to performing these exercises. The Friedman test was used to verify differences in the variables at the four moments. Significant differences in self-perception of sleep quality (with worst results in T4) and in the practice of exercises (worst results in T1) were observed. In three of the four moments of monitoring, at least one woman reported that she lacked the basics for survival. Eleven women mentioned barriers in at least one of the moments of the study to perform the exercises, being not knowing how to perform the exercise or feeling insecure performing the most mentioned barrier. Considering the need to adapt health services to the pandemic, monitoring actions, combined with listening and counseling strategies, can be a good alternative for monitoring the health of participants in physical activity groups

ABSTRACT

Introduction: Breast Imaging Reporting and Data System (BI-RADS) classification allows standardization of breast masses findings, with a recommendation for individualized management. Because of their high frequency, masses classified as 3, probably benign, arouse interest in improving their characterization and in establishing the most appropriate behavior. Objective: Firstly, to demonstrate the positive and negative predictive values of the BI-RADS 3 classification of solid masses submitted to percutaneous biopsy by ultrasonography. Secondly, to suggest a different ultrasound follow-up conduct in these findings. Methods: We retrospectively studied 480 BI-RADS 3 masses, submitted to a biopsy under vacuum or core biopsy, with a conclusive histopathological result considered the gold standard. Results: From 480 masses in 396 patients, 473 were benign and 7 malignant. The positive predictive value for malignancy of category 3 masses was 1.5% (7/480), and the negative predictive value was 98.5%. Conclusion: In view of the low probability of cancer, it is recommended the performance of directed ultrasonography (second look) of masses classified as BI-RADS 3 performed by a specialist in breast radiology before the indication of an invasive procedure, what would substantially reduce the number of unnecessary biopsies, patient's anxiety, as well as costs and possible related complications. This will increase the possibility for the specialist to spend more time on really necessary and targeted examinations, better defining cases of follow-up (annual or biannual) of the indication of investigation in specific cases.


Introdução: A classificação do Breast Imaging Reporting and Data System (BI-RADS) permite a padronização dos achados das massas mamárias, com recomendação para o manejo individualizado. Por causa de sua alta frequência, massas classificadas como 3, provavelmente benignas, despertam interesse em melhorar sua caracterização e em estabelecer o comportamento mais adequado. Objetivo: P rimeiramente, d emonstrar o s v alores p reditivos p ositivos e n egativos d a c lassificação d e m assas s ólidas B I-RADS 3 submetidos a biópsia percutânea por ultrassonografia. Em segundo lugar, sugerir conduta de acompanhamento por ultrassonografia diferente nesses achados. Metodologia: Estudamos, retrospectivamente, 480 massas BI-RADS 3, submetidas a biópsia a vácuo ou corebiopsia, com resultado histopatológico conclusivo considerado padrão-ouro. Resultados: De 480 massas em 396 pacientes, 473 eram benignas e 7 malignas. O valor preditivo positivo para malignidade de categoria 3 foi de 1,5% (7/480) e o valor preditivo negativo foi de 98,5%. Conclusão: Em vista da baixa probabilidade de câncer, recomenda-se a realização de ultrassonografia direcionada (second look) de massas classificadas como BI-RADS 3 por especialista em radiologia da mama antes da indicação de um procedimento invasivo, o que reduziria substancialmente o número de biópsias desnecessárias, ansiedade do paciente, bem como possíveis complicações. Isso aumentará a possibilidade de o especialista passar mais tempo em exames realmente necessários e direcionados, definindo melhor os casos de acompanhamento (anual ou semestral) da indicação da investigação em casos específicos.

ABSTRACT

Background: Children and teenagers accumulate dental plaque easily due to immature motor coordination present at this specific age. Thus, chemical solutions such as mouthwashes are used for biofilm control. The widespread use of mouthwash could potentially change the oral environment though there is no evidence of its effects on the biofilm. Aim: The present study aimed to investigate the in vitro antimicrobial potential of infant mouthwashes on mature Streptococcus mutans biofilm. Methods: The susceptibility of S. mutans biofilm UA 159 (ATCC700610) to infant mouthwashes was tested with childrens mouthwashes containing the following active agents: G1-cetylpyridinium chloride, G2-xylitol and triclosan and G3-Malva sylvestris and xylitol. Phosphage-buffered saline (PBS) was used at the negative control (G4). In this study, cariogenic biofilm was exposed once a day for one minute to the mouthwashes over a period of five days. Following this, an aliquot of each mouthwash used was seeded in brain heart infusion (BHI) agar and then incubated at 37°C, 5% CO2 for 48 h. The results were expressed as colony-forming units (CFU) and converted into log10. The results were submitted to ANOVA and Tukey's test at 5%. Results: It was observed 7.75, 7.66, and 7.49 CFUlog10 values to G1, G2, and G3, respectively, with 9.53 CFUlog10 value to G4. Accordingly, all studied mouthwashes showed no significant statistical difference between them but with statistically significant bacterial reduction in comparison to control group. Conclusion: Infant mouthwashes presented a highly significant antimicrobial effect on cariogenic biofilm in an in vitro model, which raises concern when used by a young population.

ABSTRACT

Abstract: This study investigates the color correspondence of resin cements and try-in pastes, and the color stability of bonded lithium disilicate ceramic disks. Resin composite disks were fabricated (n = 36) to serve as the background for lithium disilicate disks prepared in two thicknesses (0.5 and 1.0 mm, n = 18 each). Two brands were used for try-in and cement procedures: Variolink Veneer and AllCem Veneer. For baseline, water was applied between the ceramic disks and their respective backgrounds to achieve the control group. This set was subjected to color measurement using an intraoral measurement device (T0). The try-in was inserted between background and ceramic, and this set was subjected to color measurement (T1). After adhesive procedures, the ceramic disk was placed under cement, and color measurement was performed with uncured cement (T2) and 24 h after light-curing (T3). Each set was immersed in distilled water and thermal-cycled, with color measurement being performed after 10,000 (T4) and 20,000 (T5) cycles. Color differences were calculated by CIELab (rEab) and CIEDE2000 (rE00). Data were analyzed by two-way ANOVA for repeated measurements and Tukey's test (α=5%). There was color correspondence of try-in and resin cement for the Variolink system, regardless of the ceramic thickness (p > 0.05). For the AllCem system, the thickness significantly influenced the color measurement (p < 0.001). The Variolink system also demonstrated color stability after 20,000 thermal cycles with rEab < 3.46 and rE00 < 2.25. It was concluded that the color correspondence between a try-in and its respective cement may vary according to resin cement composition.

ABSTRACT

Abstract This study evaluates the shear bond strength (SBS) of various resin cements to different ceramics. Composite resin cylinders of Z100 were fabricated and cemented to disks of feldspathic ceramic (Creation), leucite-reinforced feldspathic ceramic (Empress I), and densely sintered aluminum oxide ceramic (Procera AllCeram) using five resin cements: Panavia F (PAN), RelyX ARC (ARC), RelyX Unicem (RXU), RelyX Veneer, and Variolink II. SBS was measured after three days of water storage (baseline) and after artificial aging (180 days of water storage along with 12,000 thermal cycles). Failure mode of fractured specimens also was evaluated. Data were analyzed with Kruskal-Wallis and Mann-Whitney tests (α=0.05). RXU showed 1) the lowest baseline median SBS to feldspathic ceramic, which was not statistically different from PAN; 2) the lowest median baseline SBS to leucite-reinforced feldspathic and densely sintered aluminum-oxide ceramics. All cements performed similarly after aging, except for ARC (median 0.0 MPa) and PAN (median 16.2 MPa) in the densely sintered aluminum-oxide ceramic group. Resin cements perform differently when bonded to different ceramic substrates. While all test resin cements worked similarly in the long-term to feldspathic and leucite-reinforced feldspathic ceramics, only the MDP-containing resin cement provided durable bonds to densely sintered aluminum-oxide ceramic.

ABSTRACT

Abstract Meat is one of the most perishable foods owing to its nutrient availability, high water activity, and pH around 5.6. These properties are highly conducive for microbial growth. Fresh meat, when exposed to oxygen, is subjected to the action of aerobic psychrotrophic, proteolytic, and lipolytic spoilage microorganisms, such as Pseudomonas spp. The spoilage results in the appearance of slime and off-flavor in food. In order to predict the growth of Pseudomonas fluorescens in fresh meat at different pH values, stored under refrigeration, and temperature abuse, microbial mathematical modeling was applied. The primary Baranyi and Roberts and the modified Gompertz models were fitted to the experimental data to obtain the growth parameters. The Ratkowsky extended model was used to determine the effect of pH and temperature on the growth parameter µmax. The program DMFit 3.0 was used for model adjustment and fitting. The experimental data showed good fit for both the models tested, and the primary and secondary models based on the Baranyi and Roberts models showed better validation. Thus, these models can be applied to predict the growth of P. fluorescens under the conditions tested.

ABSTRACT

Abstract The prevalence of temporomandibular disorders (TMD) is higher in females, reaching their high peak during reproductive years, probably because of the action of some female hormones, which alter pain threshold. This study aimed to investigate the prevalence of TMD in postmenopausal women and its relationship with pain and hormone replacement therapy (HRT). In total, 284 patients were evaluated and classified using the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Pain was measured using the Visual Analogue Scale (VAS), and patients were also asked about the use of HRT. All data was analyzed using analysis of variance (ANOVA) and chi-square test. In total, 155 subjects did not have TMD and 129 had TMD; TMD group patients were classified according to RDC/TMD axis I classification as follows: muscle disorder group (1.6%), disk displacement group (72.87%), and arthralgia, osteoarthritis, and osteoarthrosis group (37.98%). Pain was registered in 35 patients who belonged to the TMD group, while 48 patients reported the use of HRT. There was a similar percentage of TMD and non TMD patients; moreover, the use of exogenous hormones was no associated with TMD, suggesting that there is no influence on the pain threshold.

ABSTRACT

As cerâmicas de zircônia apresentam ótimas propriedades como biocompatibilidade, resistência flexural e dureza, tornando-se uma possível alternativa para substituição das restaurações metalocerâmicas. Entretanto, a zircônia sofre degradação superficial quando exposta ao calor e à umidade, e a utilização de estabilizadores e o domínio do processamento são relatados para melhorar a sua resistência. O uso da zircônia na Odontologia é uma realidade, mas pesquisas ainda são necessárias para avaliar seu desempenho a longo prazo na cavidade oral. Dessa forma, o objetivo deste estudo foi, através de uma revisão bibliográfica, avaliar o desempenho da zircônia como um biomaterial de uso odontológico...


Zirconia ceramics have excellent properties, such as biocompatibility, flexural strength and, hardness, and therefore are viable alternatives to metal-ceramic restorations. However, zirconia suffers superficial degradation when exposed to heat and humidity, thus the use of stabilizers and proper process of the area are important in order to improve its resistance. The use of zirconia in Dentistry is a reality, but studies are needed to assess its performance in long periods in the oral cavity. Thus, the objective of this study was to evaluate the performance of zirconia as a biomaterial for dental use through a literature review...

ABSTRACT

O objetivo deste estudo foi comparar a concordância dos exames clínico e radiográfico na detecção de cáries proximais em molares decíduos e primeiros molares permanentes. Foram selecionadas 200 crianças na faixa etária de 3 a 11 anos de idade, atendidas na Faculdade de Odontologia, da Universidade Federal do Maranhão. Todas as crianças deveriam apresentar os dentes posteriores com as cristas marginais íntegras, independente do estado das superfícies proximais. O exame clínico foi conduzido por um examinador com o auxílio de fio dental e sonda exploradora. A técnica "bite-wing" foi utilizada nas tomadas radiográficas, e a avaliação radiográfica foi realizada por um examinador utilizando negatoscópio e lupa. As características clínicas e radiográficas foram avaliadas, segundo critérios padronizados. Os dados foram analisados pelo teste McNemar com nível de significância de 5%. O exame radiográfico identificou um maior número de cáries proximais em esmalte (p<0,0001) e dentina (p<0,05), quando comparado ao exame clínico. Ao investigar o grau de concordância entre os exames, o exame radiográfico foi mais eficaz no diagnóstico de cáries proximais (p=0,0001). Conclui-se que o exame radiográfico detectou maior número de lesões cariosas proximais em relação ao clínico, sendo considerado um importante diagnóstico complementar para esse tipo de lesão.


This study aimed to compare the clinical and radiographic diagnosis for approximal caries in primary molars and first permanent molars. Two hundred children from 3 to 11 years old assisted by University Of Maranhão School Of Dentistry, were selected. All children should present the posterior teeth with intact marginal ridges, regardless of the status of proximal surfaces. Clinical examination was performed by an examiner using dental floss and dental explorer. The "bite-wing" technique was used in the radiographic examination, and radiographic analysis was performed by an examiner using a light box and a magnifying glass. The clinical and radiographic characteristics were evaluated according to standardized criteria. Data were analyzed by McNemar test with a significance level of 5%. The radiographic examination identified a higher number of proximal caries in enamel (p<0.0001) and dentin (p<0.05) compared to the clinical examination. Regarding the concordance between clinical and radiographic diagnosis, the radiographic examination was more effective in the diagnosis of proximal caries (p=0.0001). It was concluded that radiographic examination detected a higher number of proximal carious lesions in relation to clinical diagnosis, being considered as an important complement for diagnose this type of lesion.

ABSTRACT

Esta pesquisa teve por objetivo mapear indicadores de violências contra mulheres em unidades básicas de saúde de Belo Horizonte, Minas Gerais, Brasil, e identificar as dificuldades experimentadas por profissionais de saúde na notificação de violências. Dados epidemiológicos sobre esse tipo de notificação foram levantados no sistema de informações da Secretaria Municipal de Saúde. Dados qualitativos foram produzidos com questionário semiestruturado e três sessões de grupos focais, com a participação de 270 profissionais da atenção primária à saúde. Os dados foram submetidos à análise de conteúdo, sendo codificados, categorizados e discutidos à luz da revisão de literatura. Um eixo analítico central foi denominado (in)visibilidade da violência contra mulheres. Emergem dos dados tanto o reconhecimento da violência como problema de saúde pública quanto a invisibilidade que impede o seu enfrentamento. Observa-se que a notificação é frequentemente tomada como denúncia, o que dificulta o avanço nas discussões e ações concernentes ao problema.


This study aimed to map indicators of violence against women as recorded by primary healthcare services in Belo Horizonte, Minas Gerais State, Brazil, and to identify difficulties experienced by health professionals in reporting such violence. Epidemiological data on this type of notification were collected in the information system of the Municipal Health Department. Data were produced with a semi-structured questionnaire and three focus group sessions with participation by 270 primary care professionals. The data were submitted to content analysis and were coded, categorized, and discussed in light of a literature review. A central analytical axis was called (in)visibility of violence against women. The data revealed both the recognition of violence as a public health problem and the invisibility that prevents dealing with it properly. Notification of such violence is often viewed as a fuss or commotion, which hampers progress in discussing and acting on the problem.

ABSTRACT

Abordar os principais aspectos relacionados à reabilitação oral ao relatar um caso clínico utilizando prótese parcial removível (PPR) com attachment ball. Discussão: As próteses implanto-suportadas são consideradas um tratamento efetivo para a reabilitação de muitos pacientes desdentados parciais. No en¬tanto, limitações ósseas e/ou sistêmicas e o custo elevado dos implantes podem contraindicar essa modalidade terapêutica. Assim, a reabilitação oral com PPR torna-se uma ótima opção de tratamento. É conhecido que as PPRs a grampo não apresentam boa estética em muitas situações clínicas; porém, PPRs associadas a attachments permitem diversas possibilidades de soluções clínicas quando um diagnóstico e plano de tratamento mais elaborado podem ser executados. Conclusão: A PPR retida por attachment propicia resultado estético superior, transmissão adequada da carga mastigatória aos dentes suportes e excelente retenção...


To discuss the main aspects related to oral rehabilitation through the report of a clinical case using removable dental prosthesis (RDP) with ball attachment. Discussion: The implant-supported fixed restorations are considered an effective treatment for the rehabilitation of many partially edentulous patients. However, bone and/or systemic limitations and the high cost of implants may contraindicate this therapeutic modality. Thus, the oral rehabilitation using RDP becomes a great treatment option. It is known that RDP retained to a clip do not present a good esthetic in several clinical conditions; however, the RDP with attachments allows several possibilities for clinical solutions when a diagnosis and a more elaborated treatment plan can be performed. Conclusion: The RDP with attachment provides better aesthetical result, adequate transmission of masticatory load to support teeth and an excellent retention...

ABSTRACT

Aim: To compare the effectiveness of different obturation techniques in surpassing the ledgeformed in simulated curved root canals. Methods: Eighty acrylic-resin blocks with curved canalswere instrumented with Gates-Glidden drills to simulate a ledge formation. Then, a K-File #10 wasused for trying to surpass the deviation, and the blocks that permitted surpassing were rejected.The remaining blocks were divided into 4 groups according to the obturation technique: lateralcondensation, Tagger’s Hybrid technique, Thermafil and System B. The blocks had their imagesdigitalized using a scanner before and after the obturation procedures. The images were analyzedwith Image Tool 3.0 software. Statistical analysis was performed by one-way ANOVA at a significantlevel of 5%. Results: The System B resulted in the highest obturated area (p<0.001). Therewere no significant differences between the Tagger’s Hybrid technique and Thermafil systemregarding the effectiveness in surpassing ledge (p>0.05). The lateral condensation resulted in theworst ability in filling the ledge space (p<0.001). Conclusions: Within the limitations of this study,it was possible to conclude that techniques using heat condensation or gutta-perchathermoplastification were more effective in surpassing the ledge formed in curved canals than thelateral condensation.
