RESUMO
BACKGROUND: Timely diagnosis of oral cancers is critical, and performing biopsies of oral lesions with suspected malignancy is a crucial step in achieving this goal. The waiting time for the diagnosis may be related to the progression and prognosis of malignant neoplasms. OBJECTIVE: The aim of this observational, cross-sectional, national-level study was to identify the factors associated with the waiting time for scheduling an oral biopsy, based on the identification of its need. METHODS: We used secondary data from the Brazilian public health system, obtained from the 2nd cycle of the National Program to Improve Access and Quality of Dental Specialty Centers (PMAQ-CEO). The study outcome was the waiting time for scheduling an oral biopsy, starting from the identification of the need for the exam. We analyzed individual and contextual variables using multilevel statistical analysis. RESULTS: In 51.8% of DSC the waiting time for scheduling a biopsy was non-immediate; in 58.1% of CEOs, the sum of the weekly workload of dentists working in the Stomatology specialty is up to 20 h per week; in terms of coverage, 67.1% of the CEOs have only municipal coverage and 34.0% are references for up to 12 oral health teams in primary health care; only the coverage variable remained significant in the multivariate model (p < 0.05). Of the contextual variables, none of the variables remained significant (p > 0.05). When these were analyzed together, only the coverage remained significant (p < 0.05); CONCLUSION: Our analysis indicates that the waiting time for scheduling an oral biopsy is longer in CEOs that cover only one municipality and is not related to contextual factors.

BACKGROUND: This systematic review and network meta-analysis aimed to compare the clinical efficacy of bioactive and conventional restorative materials in controlling secondary caries (SC) and to provide a classification of these materials according to their effectiveness. METHODS: A search was performed in Pubmed, Web of Science, Embase, BBO, Lilacs, Cochrane Library, Scopus, IBECS and gray literature. Clinical trials were included, with no language or publication date limitations. Paired and network meta-analyses were performed with random-effects models, comparing treatments of interest and classifying them according to effectiveness in the permanent and deciduous dentition and at 1-year or 2/more years of follow-up. The risk of bias and certainty of evidence were evaluated. RESULTS: Sixty-two studies were included in the qualitative syntheses and 39 in the quantitative ones. In permanent teeth, resin composite (RC) (RR = 2.00; 95%CI = 1.10, 3.64) and amalgam (AAG) (RR = 1.79; 95%CI = 1.04, 3.09) showed a higher risk of SC than Glass Ionomer Cement (GIC). In the deciduous teeth, however, a higher risk of SC was observed with RC than with AAG (RR = 2.46; 95%CI = 1.42, 4.27) and in GIC when compared to Resin-Modified Glass Ionomer Cement (RMGIC = 1.79; 95%CI = 1.04, 3.09). Most randomized clinical trials studies showed low or moderate risk of bias. CONCLUSION: There is a difference between bioactive restorative materials for SC control, with GIC being more effective in the permanent teeth and the RMGIC in the deciduous teeth. Bioactive restorative materials can be adjuvants in the control of SC in patients at high risk for caries.

OBJECTIVE: The objective of the present study was to analyse the quality of adults and older adults health care in Primary Health Care (PHC) services in the State of Mato Grosso do Sul, 2018. METHODS: A quantitative survey was carried out in which the municipalities participating in the study included the four macro-regions following the Director Regional Plan (DRP). In this study, the quality of care was verified using the validated version of the PCAT-Br for adult and older adults users over 18 years of age and professionals. The professional's and users' views were compared between PHC attributes in the State of Mato Grosso do Sul. We performed the paired student t-test. STATA v.14.2 software (College Station, TX, USA) was used for the analyses. Sensitivity analysis was done to compare socio-demographic characteristics. RESULTS: Eight hundred twenty-five users and 424 professionals participated in the study. According to users, the Accessibility attribute had the worst performance in all macro-regions (mean score PCAT = 3.58). There were significant differences between the perception of users and professionals (PCAT = 5.32 for users and PCAT = 7.11 for professionals) in all attributes evaluated. CONCLUSIONS: There was a difference in users' and professionals' perceptions between PHC attributes. Therefore, it is necessary to strengthen PHC care networks in the State, mainly considering the users' perspectives.

BACKGROUND: Brazil experienced an expansion of the population's access to oral health policies after the creation of the Unified Health System (SUS, Sistema Único de Saúde). Through public policies, the consolidation of Primary Health Care (PHC) and the incorporation of dental care into primary and hospital care took place. The objective of this study was to identify epidemiological aspects, including the temporal trend, of hospital morbidity from oral and oropharyngeal cancer in Brazil, considering hospitalizations for this neoplasm in a hospital network linked to the public care system. METHODS: Observational study based on information on hospital admissions for oral cancer throughout Brazil. The research used data from the Brazilian Cancer Registry Information System. For the temporal series analysis, generalized linear regression model was used with the Prais-Winsten method. RESULTS: Of the 121,971 patients hospitalized with oral and oropharyngeal cancers, 76.40% were male and 23.60% were female, resulting in a M:F ratio of 3.24:1. Regarding the anatomical region of involvement among hospitalized patients with oral cavity neoplastic lesions, there was a predominance in non-specific places in the mouth, such as the floor of the mouth, soft and hard palate, among others (32.68%), followed by lesions in the region of tongue (28.89%). In this population, the predominant age group was between the fifth decade (31.09%) and sixth decade of life (24.99%); men presented neoplastic lesions of oral and oropharyngeal cancers at an earlier age than women. In all regions of the country, the staging of cases diagnosed in the tertiary health network accredited to the José Alencar Gomes da Silva National Cancer Institute (INCA) was late, with higher tendency for metastasis. The temporal trend of the adjusted in-hospital morbidity rates showed to be increasing in the Northeast, South and Midwest regions for the male gender. For females, they were increasing in the Northeast and South regions. CONCLUSIONS: It is concluded that the distribution of in-hospital morbidity rates of oral and oropharyngeal cancers in the country is irregular. There is a greater number of cases identified by the study in male patients and in the Southeast and South regions; with an increasing tendency of this coefficient in both genders.

BACKGROUND: Integrated dental services within the Health System, particularly at primary health care, are crucial to reverse the current impact of oral diseases, which are among the most prevalent diseases worldwide. However, the use of dental services is determined by complex phenomena related to the individual, the environment and practices in which care is offered. Therefore, factors associated with dental appointments scheduling can affect positively or negatively the use of dental services. The aim of the present study was to evaluate the indicators for dental appointment scheduling in Primary Health Care (PHC). METHODS: The present is a cross-sectional analytical study that used data from the external assessment of the third cycle of the National Program for Improving Access and Quality in Primary Care (PMAQ-AB), carried out between 2017 and 2018, in Brazil. The final sample consisted of 85,231 patients and 22,475 Oral Health teams (OHTs). The outcome variable was the fact that the user sought for a dental appointment at the Primary Health Care Unit. A multilevel analysis was carried out to verify the association between individual variables (related to users) and contextual variables (related to the OHTs) in relation to the outcome. RESULTS: Only 58.1% of the users interviewed at these Primary Health Care Units seek the available dental care. The variables with the greatest effect on the outcome were the patient's age up to 42 years old (OR = 2.03, 95% CI: 1.96-2.10), at individual level, and 'oral health teams that assisted no more than a single family health team (FHT)' (OR = 1.29, 95% CI: 1.23-1.36) at contextual level. Other variables were also associated with the outcome, but with a smaller effect size. CONCLUSION: In conclusion, users' age and work process of OHT were indicators for dental appointment scheduling. Our results suggest that when OHT put the National Oral Health Policy guidelines into practice, by assisting only one FHT, the chance for PHC users seeking dental appointments is higher than OHTs that assist more than one FHT. Regarding age, patients aged up to 42 years are more likely to seek an appointment with a dentist.

BACKGROUND: Oral and oropharyngeal cancers are considered important public health problems worldwide. This study aims to analyze the association between late diagnosis of oral and oropharyngeal cancers in Brazil and the contextual indicators of socioeconomic variables and coverage of Primary Health Care (PHC), and to assess the temporal trend of late diagnosis. METHODS: In this cross-sectional observational study, secondary data were evaluated with a time series analysis. All Brazilian cities that reported at least one case of oral and oropharyngeal cancers each year in the period between 2000 and 2013 were included; and the staging was analyzed by calculating the ratio risk for late diagnosis for each municipality. The association between staging and socioeconomic variables and offer of PHC was calculated using multiple linear regression. The time trend of the risk ratio for late-stage diagnosis was calculated using the Prais-Winsten method. RESULTS: One hundred and sixty Brazilian municipalities had at least one annual case of oral and oropharyngeal cancers notified to the INCA hospital system between 2000 and 2013. The adjusted model showed that the higher the Gini value (greater social inequality) and the lower the HDI value (less human development) was, the higher was the number of tumors diagnosed at a late stage, considering the size of the tumor. A greater risk for late diagnosis was identified, as early as at the stage of lymph node involvement, when there was a higher level of social inequality and lower level of coverage by Oral Health Teams (OHT) in PHC. The greater the social inequality, the greater was the risk of late diagnosis, as early as in the stage of metastasis. CONCLUSIONS: We concluded that, during the evaluated period, there was an increase in the number of cases diagnosed at the most advanced stage. Furthermore, there was association between higher levels of social inequality and an increase in the proportion of late diagnosis of oral and oropharyngeal cancers. In addition, the inclusion of Oral Health Teams in Primary Health Care promoted the early diagnosis of these types of cancers.

BACKGROUND/AIMS: Among the diseases related to oral health, such as caries and oral cancer, dental trauma stands out as one of the major public health problems worldwide. The aim of this study was to verify the occurrence of factors associated with traumatic dental injuries (TDIs), including oral health-related quality of life (OHRQoL), sociodemographic characteristics, untreated caries, occlusal problems and contextual variables in 12-year-old Brazilian children. METHODS: This study assessed a complex sample of the National Research in Oral Health (SBBrasil 2010) data on 7240 12-year-old children and contextual features of the municipalities where they lived. RESULTS: TDI prevalence in 12-year-old schoolchildren was 23.96%. Being female was a protective factor for all trauma outcome variables. Non-white children were at risk of maxillary tooth fractures. Maxillary overjet greater than 3 mm was associated with all trauma outcomes. Crowding and spacing were risk factors for enamel trauma. TDI has a negative impact on OHRQoL. None of the contextual variables analysed (Gini coefficient, MHDI, family health strategy and water fluoridation) were associated with TDI in the multilevel approach. CONCLUSIONS: TDI was better explained by individual factors, related to sociodemographic conditions and occlusal problems, with a negative impact on OHRQoL, adjusted for untreated caries. Contextual variables were not associated with TDI in 12-year-old Brazilian schoolchildren. Interdisciplinary actions for preventing dental trauma, such as stimulating the use of mouthguards, have to be encouraged by the family health strategy (FHS) and school health programme (SHP).

OBJECTIVE: The aim of this study was to investigate, at a national level, which individual factors of the work process/infrastructure are associated with the achievement of goals in the periodontics specialty in Brazilian Dental Specialty Centers (BDSC). METHODS: This was a quantitative, analytical, cross-sectional study. Secondary data from DATASUS and the external evaluation of the second cycle of the BDSC Access and Quality Improvement Program were used. Variable description was carried out in the first stage, and then the bivariate Poisson regression was performed to verify possible associations between the variables and the outcome (achievement of goals in Periodontics in the BDSC). In this analysis, the covariates that were associated with the outcome at the p <0.20 significance level were included in the next step of the analysis. Multivariate Poisson regression with a robust estimator was then performed with those that met the above criterion. The variables that showed a p value < 0.05 were considered in the final model. RESULTS: The outcome was achieved in more than seven months of the year (mean 7.03 months, SD 4.20). Most BDSC monitored the established goals (93.2%), had referral as the only way of access (61.7%), had only municipal coverage (68.4%), carried out planning and periodic evaluation of actions (89.2%). A minority has quotas of procedures by Oral Health teams (OHTs) in Primary Health Care (PHC) (18.8%). The presence of a specialist in periodontics was (on average) 1.16 per BDSC and the sum of the workload of dentists working in this specialty was 31.1 hours (SD = 23.9). CONCLUSION: It was concluded that the individual factors of the work process/infrastructure associated with the achievement of goals in periodontics in Brazilian BDSC are: monitoring of established goals, BDSC scope and number of professionals working in the specialty.

The field of probiotic applications is rapidly expanding, including their use for the control of respiratory tract infections. Nevertheless, probiotics ability to colonize the lung environment and to compete with pulmonary pathogens is still a poorly investigated research area. In this study, we aimed to evaluate the adhesion ability of a number of commercial probiotic strains to the human lung epithelial cell line A549. Furthermore, we assessed probiotic ability to prevent host cell adhesion of one of the major lung pathogens in cystic fibrosis, Pseudomonas aeruginosa, and to reduce the pathogen-induced inflammatory response of human peripheral blood mononuclear cells (PBMCs) in terms of cytokine release. Lactobacillus acidophilus displayed the highest adhesion ability to A549 cells evaluated as percent of adhered bacteria compared to the inoculum. In agreement with such an observation, L. acidophilus was the most efficient in preventing adhesion to A549 cells of a P. aeruginosa isolate from CF sputum. Three-color fluorescence labeling of A549 cells, P. aeruginosa, and L. acidophilus, and confocal microcopy image analyses revealed a likely exclusion effect played by both live and UV-killed L. acidophilus towards P. aeruginosa. Such results were confirmed by CFU count. When co-cultured with PBMCs, both live and UV-killed L. acidophilus reduced the amount of IL-1ß and IL-6 in culture supernatants in a statistically significant manner. Overall, the results obtained point to L. acidophilus as an interesting candidate for further studies for a potential aerogenous administration to control P. aeruginosa infections.
RESUMO
Mechanisms underlying vascular endothelial susceptibility to infection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are not fully understood. Emerging evidence indicates that patients lacking von Willebrand factor (vWF), an endothelial hallmark, are less severely affected by SARS-CoV-2 infection, yet the precise role of endothelial vWF in modulating coronavirus entry into endothelial cells is unknown. In the present study, we demonstrated that effective gene silencing by short interfering RNA (siRNA) for vWF expression in resting human umbilical vein endothelial cells (HUVECs) significantly reduced by 56% the cellular levels of SARS-CoV-2 genomic RNA. Similar reduction in intracellular SARS-CoV-2 genomic RNA levels was observed in non-activated HUVECs treated with siRNA targeting angiotensin-converting enzyme 2 (ACE2), the cellular gateway to coronavirus. By integrating quantitative information from real-time PCR and high-resolution confocal imaging, we demonstrated that ACE2 gene expression and its plasma membrane localization in HUVECs were both markedly reduced after treatment with siRNA anti-vWF or anti-ACE2. Conversely, siRNA anti-ACE2 did not reduce endothelial vWF gene expression and protein levels. Finally, SARS-CoV-2 infection of viable HUVECs was enhanced by overexpression of vWF, which increased ACE2 levels. Of note, we found a similar increase in interferon-ß mRNA levels following transfection with untargeted, anti-vWF or anti-ACE2 siRNA and pcDNA3.1-WT-VWF. We envision that siRNA targeting endothelial vWF will protect against productive endothelial infection by SARS-CoV-2 through downregulation of ACE2 expression and might serve as a novel tool to induce disease resistance by modulating the regulatory role of vWF on ACE2 expression.

Recent evidence suggests that lipids play a crucial role in viral infections beyond their traditional functions of supplying envelope and energy, and creating protected niches for viral replication. In the case of Zika virus (ZIKV), it alters host lipids by enhancing lipogenesis and suppressing ß-oxidation to generate viral factories at the endoplasmic reticulum (ER) interface. This discovery prompted us to hypothesize that interference with lipogenesis could serve as a dual antiviral and anti-inflammatory strategy to combat the replication of positive sense single-stranded RNA (ssRNA+) viruses. To test this hypothesis, we examined the impact of inhibiting N-Acylethanolamine acid amidase (NAAA) on ZIKV-infected human Neural Stem Cells. NAAA is responsible for the hydrolysis of palmitoylethanolamide (PEA) in lysosomes and endolysosomes. Inhibition of NAAA results in PEA accumulation, which activates peroxisome proliferator-activated receptor-α (PPAR-α), directing ß-oxidation and preventing inflammation. Our findings indicate that inhibiting NAAA through gene-editing or drugs moderately reduces ZIKV replication by approximately one log10 in Human Neural Stem Cells, while also releasing immature virions that have lost their infectivity. This inhibition impairs furin-mediated prM cleavage, ultimately blocking ZIKV maturation. In summary, our study highlights NAAA as a host target for ZIKV infection.

A marked reorganization of internal membranes occurs in the cytoplasm of cells infected by single stranded positive-sense RNA viruses. Most cell compartments change their asset to provide lipids for membrane rearrangement into replication organelles, where to concentrate viral proteins and enzymes while hiding from pathogen pattern recognition molecules. Because the endoplasmic reticulum is a central hub for lipid metabolism, when viruses hijack the organelle to form their replication organelles, a cascade of events change the intracellular environment. This results in a marked increase in lipid consumption, both by lipolysis and lipophagy of lipid droplets. In addition, lipids are used to produce energy for viral replication. At the same time, inflammation is started by signalling lipids, where lysosomal processing plays a relevant role. This review is aimed at providing an overview on what takes place after human class IV viruses have released their genome into the host cell and the consequences on lipid metabolism, including lysosomes.

BACKGROUND: Congenital syphilis (CS) is a problem of great concern for public health, especially in Brazil. The aim of this study was to analyse the time trends and the space-time dynamics of morbidity and mortality from CS in Brazil. METHODS: An ecological and time series study, which included all cases and deaths from CS recorded in a national Brazilian database from 2013 to 2019 was performed. Time trends in CS incidence and mortality were assessed using segmented linear regression. Univariate global and local Moran indices and space-time scan statistics were used in the space and space-time analyses. RESULTS: A total of 183 171 cases and 2401 deaths from CS were recorded in Brazil, with the highest number of cases being observed in the Southeast Region (n=82 612 [45.1%]). Only 21.1% of pregnant mothers with syphilis received adequate treatment. There was an upward trend in CS rates among mothers ages 20-29 y (average annual percent change [AAPC] 1.4 [95% confidence interval {CI} 1.0 to 1.7]) and with <8 y of schooling (AAPC 6.6 [95% CI 5.3 to 7.9]). The primary space-time cluster involved 338 municipalities in the Southeast Region (relative risk 3.06, p<0.001) and occurred between 2017 and 2019. CONCLUSIONS: To reduce the trends in CS rates, it is necessary to develop actions to improve the quality of prenatal care and expand early diagnosis and adequate treatment of syphilis in pregnant women and their sexual partners, especially in groups with upward trends (mothers ages 20-29 y and <8 y of schooling) and living in higher-risk regions (Southeast, North and Northeast).

BACKGROUND: Chikungunya fever is considered an abrupt onset arbovirus transmitted by mosquitoes, mainly Aedes aegypti and Aedes albopictus. The disease has a significant impact on the quality of life of affected persons, and many of its numerous symptoms have not yet been properly clarified, such as the manifestations that can occur in the oral cavity. The aim of this study was to identify the main oral manifestations related to chikungunya fever, as well as describe the demographic characteristics of patients, by conducting a systematic review of the literature. METHODS AND FINDINGS: Searches were performed in MEDLINE (PubMed), Embase (Elsevier), LILACS (VHL), Cochrane Library, Scopus, and CAPES electronic databases for theses and dissertations published up to January 16, 2021 without language and date restrictions. Additional manual searches of gray literature, reference list, and Google Scholar were carried out. We included 27 studies highlighting mainly oral manifestations that cause masticatory discomfort such as ulcers and oral thrush, gingival bleeding, pain and burning of the oral mucous membranes, temporomandibular joint (TMJ) arthralgia, opportunistic infections, and changes in taste. CONCLUSIONS: There seems to be a predominance of oral manifestations that cause discomfort when chewing, such as ulcerations in the acute phase of the disease, with complete remission within 3 to 10 days after the onset, apparently mostly affecting women and older persons. These oral manifestations can be compatible with basic viral infections related to inflammatory response and transitory immunosuppression.

OBJECTIVE: This study investigated whether the presence of care workers who completed a specialization course on family health was associated with improved care and maternal and child health indicators in municipalities in the state of Mato Grosso do Sul, Brazil. METHODS: Negative binomial regression models with fixed effects were used for the 79 municipalities in the state of Mato Grosso do Sul, with repeated observations for the period 2009-2015. For our reference, the parameter "number of professionals who completed the course" calculated the proportion of professionals who completed the course, and was divided by the total number of primary health care professionals in the municipality to create a ratio. The cutoff points used represented tertile distribution: T3: high (0.35-1.00), T2: intermediate (0.02-0.33) and T1: low (0.00-0.01); to avoid biased results, the analysis was also performed for the years prior to the beginning of the course in question (2009 and 2010). RESULTS: During the study period, enrollment of pregnant women, exclusive breastfeeding for children under 4 months, and up-to-date vaccinations in children younger than 1 year to 23 months increased (high to intermediate categories) in municipalities where professionals who completed the specialization course worked. Growth in the intermediate ratio was also observed in indicators related to cervical cancer screening and new diagnoses of congenital syphilis in infants under one year of age. CONCLUSIONS: The presence of care workers who completed a specialization course on family health was seen to be associated with improved care and indicators for maternal and child health in municipalities in the state of Mato Grosso do Sul, Brazil. These findings reaffirm the importance and effectiveness of policies on training and continuing education for the Brazilian Unified Health System.

OBJECTIVE: The objective of this study was to verify whether the inclusion of professionals who completed a specialized distance learning course in family health teams is associated with rates of hospitalization for primary healthcare-sensitive conditions and better monitoring of chronic conditions in municipalities within the state of Mato Grosso do Sul, Brazil. METHODS: Negative binomial regression models with fixed effects were used for the 79 municipalities in the state, with repeated observations for the selected years (2009-2015). For our reference, the parameter "Municipality Ratio" was the number of professionals who completed the course divided by the total number of PHC professionals in the municipality. This ratio has been cumulative over the years. No reference values were found in the scientific literature, so three cutoff points were used for tertile distribution: T3:high (0.35-1.00), T2:intermediate (0.02-0.33), and T1:Low (0.00-0.01). In order to avoid capturing biased results, the analysis was also performed for the years before the specialization course was offered (2009 and 2010). RESULTS: Indicators of the share of hospitalizations for primary care-sensitive conditions (overall rate and specific rates for asthma, gastroenteritis, and heart failure) decreased during the study period when related to a high and intermediate proportion of professionals who completed the specialization course, and the same was seen for indicators of chronic conditions (diabetic and hypertensive patients) who were registered, monitored and group care. CONCLUSION: The specialization course impacted important indicators related to the attributions of primary health care professionals, considering that decreases in hospitalizations for primary care sensitive causes (overall rate of sensitive causes, specific rates for asthma, gastroenteritis and heart failure) were seen in the territories where professionals who completed this course worked, along with increased registration and monitoring of diabetic and hypertensive patients.

Studies on the impacts of drought usually make the implicit assumption that there will always be a negative effect on the environment, the economy and society. However, other approaches, based for example on the framework provided by the consumer surplus theory, try to focus on the distributive effects of drought. In this paper, in the wake of such approaches, we address the question of the distributive effects of drought on agriculture, exploring and studying in depth the characteristics, the signs and the magnitude of the socio-economic impacts of droughts on specific significant agricultural areas in Europe. According to our estimations, essentially based on the analysis of trends and changes in production and prices, we found that drought events can create not only "losers", but also "winners". Some social groups (for example, some categories of farmers) can even "win", while others "lose" (for example, final consumers). These findings apparently introduce questions of social justice in the evaluation of the impacts of climate change.
RESUMO
The scope of this study was to identify individual and contextual factors associated with the self-perceived need for dental treatment and for prostheses among elderly Brazilians. An analysis was performed with data from the SB Brazil 2010 epidemiological survey conducted by the Ministry of Health with a sample of 7,619 elderly individuals. Multilevel logistic regression models of mixed random and fixed effects were used to the estimate odds ratio (OR) with 95% confidence interval (95% CI) between the dependent variables and individual and contextual factors. Of the individuals assessed, 3,848 (50.5%) reported a need for dental treatment and 4,236 (55.6%) believed they have the need for prostheses. The results of multilevel logistic regression showed that gender, self-reported skin color, income and coverage by the oral health teams in the Family Health Program were associated with self-perception. This study revealed a greater influence of individual factors on the self-perceived need for dental treatment and prostheses by elderly Brazilians. This information can help to identify the inequalities that affect this population group and in setting priorities for the planning of health services.
Este estudo teve como objetivo identificar fatores individuais e contextuais associados à autopercepção da necessidade de tratamento odontológico e de prótese em idosos brasileiros. Foram utilizados dados secundários de 7.619 indivíduos idosos do levantamento epidemiológico SB Brasil 2010. As associações entre as variáveis dependentes e os fatores individuais e contextuais foram estimadas através da razão de chances (odds ratio OR) e intervalo de confiança de 95%, obtidas por regressão logística multinível. Dos idosos avaliados pelo SB Brasil 2010, 3.848 (50,5%) afirmaram necessitar de tratamento odontológico e 4.236 (55,6%) acreditavam necessitar de prótese. Os resultados da regressão logística multinível mostraram que sexo, cor da pele autorreferida, renda e cobertura pelas equipes de saúde bucal na Estratégia de Saúde da Família estiveram associados à autopercepção. O presente trabalho evidenciou maior influência de fatores individuais na autopercepção da necessidade de tratamento odontológico e de prótese entre idosos brasileiros. Essas informações podem auxiliar na identificação de desigualdades que afetam essa parcela da população e na definição de prioridades para o planejamento dos serviços de saúde.

This study aimed to conduct an integrative review of scientific literature on the topic of Oral Health in the Family Health Strategy in the period 2004-2014. Articles published in national and international journals (n = 141) were consulted and selected from the electronic Library the Scientific Electronic Library Online (SciELO) and from electronic databases PubMed, Lilacs, BBO and Cochrane. The implementation process of oral health teams in the Family Health Strategy was the most frequent thematic variable (18%) of the 15 variables identified. The Northeast was the Brazilian macro-region where the largest number of published articles originated (n = 61). The studies were predominantly quantitative, and the highest number of publications occurred in 2010 (n = 26). We concluded that there is an increasing interest in investigating the context of oral health implementation in the Family Health Strategy, with particular emphasis on theme categories related to the micro-process work and the redefinition of professional identities arising from multidisciplinary work in primary care.

BACKGROUND: Tutored laboratorial activities could be a manner of improving the competency development of students. However, its impact over conventional theoretical classes has not yet been tested. Additionally, different university contexts could influence this issue and should be explored. OBJECTIVE: To assess the impact of a tutored theoretical-practical training for teaching undergraduate students to detect caries lesions as compared with theoretical teaching activities. The impact of these teaching/learning activities will be assessed in terms of efficacy, cost/benefit, retention of knowledge/acquired competences, and student acceptability. METHODS: Sixteen centers (7 centers from Brazil and 9 centers from other countries throughout the world) are involved in the inclusion of subjects for this protocol. A randomized controlled study with parallel groups will be conducted. One group (control) will be exposed to a 60- to 90-minute conventional theoretical class and the other group (test) will be exposed to the same theoretical class and also a 90-minute laboratory class, including exercises and discussions based on the evaluation of a pool of images and extracted teeth. The mentioned outcomes will be evaluated immediately after the teaching activities and also in medium- and long-term analyses. To compare the long-term outcomes, students who enrolled in the university before the participating students will be interviewed for data collection and these data will be used as a control and compared with the trained group. This stage will be a nonrandomized phase of this study, nested in the main study. Appropriate statistical analysis will be performed according to the aims of this study. Variables related to the centers will also be analyzed and used to model adjustment as possible sources of variability among results. RESULTS: This ongoing study is funded by a Brazilian national funding agency (CNPq- 400736/2014-4). We expect that the tutored theoretical-practical training will improve the undergraduate students' performance in the detection of caries lesions and subsequent treatment decisions, mainly in terms of long-term retention of knowledge. Our hypothesis is that tutored theoretical-practical training is a more cost-effective option for teaching undergraduate students to detect caries lesions. CONCLUSIONS: If our hypothesis is confirmed, the use of laboratory training in conjunction with theoretical classes could be used as an educational strategy in Cariology to improve the development of undergraduate students' skills in the detection of caries lesions and clinical decision-making.
