ABSTRACT BACKGROUND: Specific types of violence such as intimate partner sexual violence and intimate partner homicide occur more frequently in rural areas. OBJECTIVE: This study aimed to systematically review the literature on the knowledge and attitudes of rural healthcare providers regarding cases of domestic violence against women. DESIGN AND SETTING: Systematic review developed at Universidade Federal de Uberlândia. METHODS: We conducted an electronic search of six databases, which only included observational studies, regardless of the year, language, or country of publication, except for studies that used secondary data and were exclusively qualitative. Two reviewers performed the selection, data extraction, and risk of bias assessment using a specific Joanna Briggs Institute tool. RESULTS: Six studies met the inclusion criteria. All the studies had a low risk of bias. Approximately 38% of these professionals identified injuries caused by violence in patients. When asked about knowing the correct attitude to take in cases of confirmed violence, between 12% and 64% of rural healthcare providers answered positively; most of them would refer to specialized institutions and promote victim empowerment and counseling. The number of professionals with an educational background in the field ranged from 16% to 98%. CONCLUSIONS: The evident disparity across studies shows that some professionals have suboptimal knowledge and require training to adopt the correct attitude when identifying female victims of domestic violence in clinical practice. SYSTEMATIC REVIEW REGISTRATION: This systematic review was registered in the Open Science Framework Database under the registration http://doi.org/10.17605/OSF.IO/B7Q6S.

Abstract This study aimed to assess the traumatic dental injuries (TDIs) in permanent dentition among patients who attended at the outpatient clinic of a Brazilian dental school, during the last 20 years, and to investigate factors associated with the severity of these injuries. Clinical records of patients who attended a specialized center for dental trauma care in Brazil presenting at least one TDI in a permanent tooth, between the years 2000 and 2019, were reviewed. The data recorded were sex, age, affected arch, etiology, number, and type of the teeth affected, and classification and severity of the TDIs. The diagnosis and classification of the TDIs were based on the guidelines of the International Association of Dental Traumatology (IADT). The severity of each patient's injuries was defined as mild, moderate, or severe. Descriptive statistics, chi-square and multinomial regression analyses were used to evaluate the results. The significance level was set at 5%. A total of 837 clinical records were included, totaling 2357 teeth. Males were more prevalent than females. The patients' age ranged from 5 to 71 years. The most common traumas were avulsion (n=512) and uncomplicated enamel-dentin fracture (n=488). Univariate analyses showed that there was a statistically significant association between age group (p=0.004), etiology (p=0.000) and number of teeth affected (p=0.000) with severity of dental trauma. In conclusion, TDIs that occurred in Piracicaba and region are epidemiologically similar to those found worldwide, and that more severe injuries are related to age range, etiology and number of teeth affected.

Resumo Esse estudo objetivou avaliar as injúrias dentárias traumáticas (IDTs) na dentição permanente entre os pacientes que compareceram ao ambulatório de uma faculdade de odontologia brasileira, durante os últimos 20 anos, e investigar fatores associados à severidade dessas lesões. Os registros clínicos dos pacientes que compareceram a um centro especializado de atendimento em traumatismo dentário no Brasil apresentando pelo menos uma IDT em dente permanente, entre os anos de 2000 e 2019, foram revisados. Os dados registrados foram sexo, idade, arco dental afetado, etiologia, número e tipo dos dentes afetados, e classificação e severidade das IDTs. O diagnóstico e a classificação das IDTs foram baseados nas diretrizes da Associação Internacional de Traumatologia Dentária (AITD). A gravidade das lesões de cada paciente foi definida como leve, moderada ou severa. Estatísticas descritivas, teste qui-quadrado e análises de regressão multinomial foram usadas para avaliar os resultados. O nível de significância foi fixado em 5%. Um total de 837 registros clínicos foi incluído, totalizando 2357 dentes. O sexo masculino foi mais prevalente que o feminino. A idade dos pacientes variou de 5 a 71 anos. Os traumas mais comuns foram avulsão (n=512) e fratura não-complicada do esmalte-dentina (n=488). As análises univariadas mostraram que houve associação estatisticamente significativa entre a faixa etária (p=0,004), etiologia (p=0,000) e número de dentes afetados (p=0,000) com a gravidade do traumatismo dentário. Em conclusão, as IDTs que ocorreram em Piracicaba e região são epidemiologicamente semelhantes aos encontrados em todo o mundo, e que lesões mais graves estão relacionadas à faixa etária, etiologia e número de dentes afetados.

Abstract This study aimed to assess the potential association between perception malocclusion and school performance in children and adolescents. An electronic search was performed in ten databases. Based on the PECO acronym (Population, Exposition, Comparator, and Outcome), the eligibility criteria included observational studies that compared the school performance of children and adolescents with and without the perception of malocclusion. There were no restrictions on the language or year of publication. Two reviewers selected the studies, extracted the data, and assessed the risk of bias by using the Joanna Briggs Institute tool for cross-sectional studies. School performance was measured by analyzing student grades; levels of absenteeism; and child or adolescent self-perception and/or the perception of parents, guardians, close friends, and teachers regarding the impact of malocclusion on school performance. The data were described narratively/descriptively. The search resulted in 3,581 registers, of which eight were included in the qualitative synthesis. These studies were published between 2007 and 2021. Two studies concluded that there was no significant association between school performance and perception of malocclusion, five studies found that only some of the children with malocclusion had their school performance affected, and one study concluded that there was a significant association between perception of malocclusion and low school performance. Considering all variables and the very low certainty of evidence, the perception of malocclusion seems to negatively impact school performance when associated with external and subjective factors. Further studies using additional measurement standards are required.

Abstract The aim of this review was to evaluate the prevalence of dental caries, periodontal disease, malocclusion, and tooth wear in indigenous in Brazil. A systematic review of observational studies was performed according to the PRISMA guidelines (CRD42020218704). The search strategy involved the electronic databases of Embase, LILACS, PubMed, Web of Science, Scopus, and the CAPES Theses and Dissertations for gray literature. The eligibility criteria consisted of publications that assessed the prevalence of oral conditions in indigenous populations in Brazil. Studies with indigenous people living in urban area were excluded. The risk of bias was evaluated by using JBI Critical Appraisal for prevalence studies. Thirty studies were included in the review, and the majority showed a low risk of bias. A meta-analysis of 20 studies was conducted using the random-effects model and a 95% confidence interval. Several ethnicities were studied in isolation or in groups (n = 7,627 for dental caries; n = 2,774 for periodontal disease; n = 1,067 for malocclusion; n = 150 for tooth wear). The prevalence of caries ranged from 50% among indigenous people aged 18-36 months to 100% among those aged 65–74 years. The prevalence of periodontal disease ranged from 58% to 83%. The prevalence of malocclusion was 43%. Tooth wear was assessed in only one ethnic group and showed a prevalence of 100% in indigenous people aged >18 years. The certainty of evidence assessed by the GRADE system ranged from very low to moderate. This systematic review showed significant differences in the prevalence of dental caries, periodontal disease and malocclusion between indigenous population groups and territories in which indigenous people live.

Abstract Lipolytic substance injections to reduce localized fat have been extensively used because it is a low-invasive method. This review aimed to evaluate the efficacy and safety of deoxycholic acid in submental fat reduction compared to a placebo and investigate the potential industry sponsorship bias in the results of randomized clinical trials on this topic. Ten electronic databases were extensively searched for randomized clinical trials without restriction on language and year of publication. Two reviewers extracted the data and assessed the individual risk of bias in the studies with the RoB 2.0 tool. The industry sponsorship bias was evaluated according to citations in the articles regarding industry funding/sponsorship throughout the texts. Fixed and random effects meta-analyses were performed, and the results were reported in Risk Ratio (RR) at a 95% Confidence Interval (95% CI). The initial search provided 5756 results, of which only five were included. Only two studies had a low risk of bias. All studies showed a potential industry bias. The meta-analysis showed that patients treated with deoxycholic acid had significant positive results for all efficacy outcomes and a higher risk of fibrosis, pain, erythema, numbness, swelling, edema, pruritus, nodules, headache, and paresthesia. The low to moderate certainty of evidence found allows concluding that deoxycholic acid is effective in submental fat reduction, causing well-tolerated adverse effects. However, all eligible studies showed a potential industry bias.

Aim The objective of this study was to describe a case series concerning internal bleaching of anterior traumatized teeth that underwent regenerative endodontic procedures (REP). Methods Seven non-vital maxillary anterior teeth discolored after regenerative endodontic procedures were included and divided into two groups according to the medication protocol used in the REP: (1) Triple antibiotic paste (TAP) group (n=4); (2) Calcium hydroxide and 2% chlorhexidine gel (HC+CHX) (n=3). The bleaching technique used was walking bleach, where sodium perborate associated with distilled water was used. Bleaching agent was replaced weekly until the darkened tooth was slightly lighter than the adjacent tooth. The color was recorded with the aid of a digital spectrophotometer in two moments (T1: prior the first session of bleaching, T2: fourteen days after the last session of bleaching). The change in color after the procedure (ΔE) was calculated and reported in a descriptive analysis. Results The ΔE for all teeth showed color differences exceeding the perceptibility threshold (ΔE > 3.7). Both groups showed similar ΔE (TAP: 18.3 ± 11.5; HC+CHX: 14 ± 11.2) at the end of the treatment. The average number of sessions needed to achieve satisfactory results was 1.7 ± 0.6 for HC+CHX group and 2.3 ± 0.5 for TAP group. Conclusion Internal bleaching with sodium perborate associated with distilled water is effective in treating discolored teeth after regenerative endodontic procedures.

ABSTRACT BACKGROUND: Individuals’ quality of working life and motivation are directly related to their satisfaction and wellbeing. Although studies on the quality of life of family health workers have been conducted, there are none correlating these professionals’ wellbeing with this work model. OBJECTIVE: To review the scientific literature in order to identify the levels of quality of life, in their dimensions, of Family Health Strategy workers. DESIGN AND SETTING: Systematic review of observational studies developed through a partnership between two postgraduate schools (Piracicaba and Uberlândia). METHODS: The review followed the PRISMA recommendations and was registered in the PROSPERO database. Ten databases were used, including the “grey literature”. Two evaluators selected the eligible studies, collected the data and assessed the risk of biases, independently. The JBI tool was used to assess the risk of bias. A complementary statistical analysis was conducted on the means and standard deviations of the results from the WHOQOL-100 and WHOQOL-bref questionnaires. RESULTS: The initial search presented 1,744 results, from which eight were included in the qualitative analysis. The studies were published between 2007 and 2018. The total sample included 1,358 answered questionnaires. All the studies presented low risk of bias. The complementary analysis showed that the environmental factor (mean score 56.12 ± 2.33) had the most influence on the quality of life of community health workers, while physical health (mean score 14.29 ± 0.21) had the most influence on graduate professionals. CONCLUSION: Professionals working within the Family Health Strategy had dimensions of quality of life that varied according to their professional category.

Resumo Este relato de caso teve como objetivo descrever um acompanhamento de dez anos após o tratamento imediato de múltiplos traumas dentários. Uma paciente do sexo feminino de quinze anos compareceu a uma clínica privada trinta minutos após um acidente na escola. Após exames clínicos e radiográficos, o dente 21 foi diagnosticado com fratura de esmalte e fratura radicular horizontal, o dente 22 foi diagnosticado com luxação lateral, e os dentes 12, 11 e 23 foram diagnosticados com subluxação. Os dentes 21 e 22 apresentaram necrose pulpar e foram tratados endodonticamente. O dente 21 foi obturado com uma pasta composta de hidróxido de cálcio, gel de clorexidina 2% e óxido de zinco, e o dente 22 foi obturado de maneira convencional. Após acompanhamento de dez anos, os dentes 21 e 22 não apresentam reabsorção radicular ou lesão periapical, enquanto os dentes 12, 11 e 23 continuam apresentando vitalidade pulpar.

Abstract This case report aims to describe a long-term follow-up after the immediate treatment of multiple dental injuries. A 15-year-old female patient was admitted to a private clinic 30 minutes after an accident at school. After clinical and radiographic examinations, tooth 21 was diagnosed with enamel fracture and horizontal root fracture, tooth 22 was diagnosed with lateral luxation, and teeth 12, 11, and 23 were diagnosed with subluxation. Teeth 21 and 22 presented pulp necrosis resulting in root canal treatment. Moreover, tooth 21 was filled with a paste composed of calcium hydroxide, 2% chlorhexidine gel, and zinc oxide, and tooth 22 was filled conventionally. After a 10-year follow-up, her teeth 21 and 22 showed no root resorption or periapical lesion, while her teeth 12, 11, and 23 still presented pulpal vitality.

Resumo O objetivo deste estudo foi avaliar e comparar a imunoexpressão de RANK, RANKL e OPG em cisto dentígero, ceratocisto odontogênico e ameloblastoma. O protocolo foi registrado no PROSPERO (CRD [Oculto]). Sete bancos de dados (Embase, Lilacs, LIVIVO, PubMed, Scopus, SciELO e Web of Science) foram as principais fontes de pesquisa e duas bases de dados (Open Grey e Open Thesis) capturaram parcialmente a “literatura cinza”. Apenas estudos transversais foram incluídos. A ferramenta JBI avaliou o risco de viés. Uma metanálise com modelo de efeitos aleatórios estimou os valores da razão OPG e RANKL relatados pelos estudos individuais e seus respectivos intervalos de confiança de 95%. A heterogeneidade entre os estudos foi avaliada por meio do teste I2. Apenas nove estudos preencheram os critérios de inclusão e foram considerados nas análises. Os estudos foram publicados entre 2008 e 2018. Dois estudos apresentaram baixo risco de viés, enquanto sete estudos apresentaram risco moderado. A meta-análise mostrou a maior razão OPG> RANKL para cisto dentígero (ES=43,3%; IC95%=14,3-74,8) e ceratocisto odontogênico (ES=36,8%; IC95%=18,8-56,7). Por outro lado, a maior razão OPG <RANKL foi encontrada para ameloblastoma (ES=73,4%; IC95%=55,4-88,4) e foi maior na região estromal em comparação com a região epitelial odontogênica. Os resultados podem explicar o potencial agressivo do ameloblastoma devido a uma maior proporção OPG <RANKL nesse tumor, enquanto tal proporção foi menor no cisto dentígero e no ceratocisto odontogênico.

Abstract The aim of this study was to assess and compare RANK, RANKL, and OPG immunoexpression in dentigerous cyst, odontogenic keratocyst, and ameloblastoma. The protocol was registered in PROSPERO (CRD42018105543). Seven databases (Embase, Lilacs, LIVIVO, PubMed, Scopus, SciELO, and Web of Science) were the primary search sources and two databases (Open Grey and Open Thesis) partially captured the “grey literature”. Only cross sectional studies were included. The JBI Checklist assessed the risk of bias. A meta-analysis with random effects model estimated the values from the OPG and RANKL ratio reported by the individual studies and respective 95% confidence intervals. The heterogeneity among studies was assessed with I2 statistics. Only nine studies met the inclusion criteria and were considered in the analyses. The studies were published from 2008 to 2018. Two studies presented low risk of bias, while seven studies presented moderate risk. The meta-analysis showed the highest OPG>RANKL ratio for dentigerous cyst (ES=43.3%; 95% CI=14.3-74.8) and odontogenic keratocyst (ES=36.8%; 95% CI=18.8-56.7). In contrast, the highest OPG<RANKL ratio was found for ameloblastoma (ES=73.4%; 95% CI=55.4-88.4) and it was higher in the stromal region compared to the odontogenic epithelial region. The results may explain the aggressive potential of ameloblastoma from the higher OPG<RANKL ratio in this tumor, while it was lower for dentigerous cyst and odontogenic keratocyst.

Abstract This study aimed to assess whether the reductions in serum urea and creatinine levels are different from the reductions in salivary urea and creatinine levels that occur after hemodialysis in chronic renal patients. The systematic review protocol was registered in the PROSPERO database. Eight databases were searched to identify pretest-posttest studies of chronic kidney disease patients undergoing hemodialysis, with no language or year restrictions. The JBI Critical Appraisal Tool was used to assess the risk of bias. Meta-analyses using random-effect models were conducted to compare salivary and serum correlations and to pooled mean and proportion differences from pre- to posthemodialysis urea and creatinine levels by subgroup analysis. The I2 test was used to assess heterogeneity, and a meta-regression was performed to statistically assess correlations and differences in the pooled effects pre- and postdialysis. The Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) was used to assess the certainty of evidence. The search resulted in 1404 records, and only six studies (n = 252 participants) fulfilled the eligibility criteria and were included. The studies were published between 2013 and 2018. All studies showed a significant reduction in both salivary and serum urea/creatinine levels. All eligible studies presented a low risk of bias. The meta-analysis shows a moderate to high correlation between salivary and blood levels of urea (r: 0.79; 95% CI: 0.56-1.00) and creatinine (r: 0.64; 95%CI: 0.16–1.00), with a very low level of certainty. The reductions in salivary urea and creatinine levels are similar to and correlated with the reductions in blood urea and creatine levels after hemodialysis among chronic kidney disease patients.

This study aimed to systematically review the literature to assess the effect of preemptive intravenous ibuprofen on pain reduction after lower third molar surgery. Nine databases (PubMed, Scopus, LILACS, SciELO, Embase, Web of Science, Cochrane, Open Gray, and Open Thesis) were used as sources of research, including “grey literature.” The protocol was registered in PROSPERO. Only randomized clinical trials evaluating the effects of preemptive intravenous ibuprofen on pain during and immediately after the extraction of lower third molars were included, without restrictions of year and language. Two reviewers independently performed the study selection, data extraction, and assessment of the risk of bias. The “Joanna Briggs Institute for Randomized Controlled Trials” tool was used to assess the risk of bias. Each study was categorized according to the percentage of positive responses to the questions corresponding to the assessment instrument. The results were measured narratively/descriptively. The initial search resulted in 3,257 records, of which only three studies (n=150 participants) met the eligibility criteria and were included in the qualitative analysis. All studies were published in 2019. The risk of bias ranged from low to moderate. Two studies found significant pain reduction within 48 h after the procedure. In conclusion, the use of preemptive intravenous ibuprofen for extracting third molars reduces pain and analgesic consumption after the surgical procedure.

Abstract: This study aimed to assess the survival of glass ionomer cement (GIC) restorations performed using the atraumatic restorative treatment (ART) in elderly patients. The systematic review protocol was registered in the PROSPERO database. The records were searched until August 2020 in eight electronic bibliographic databases, and included randomized and non-randomized clinical trials and observational studies, with no restrictions on the language or year of publication. Study selection and data extraction were performed independently by two reviewers. Data were extracted, summarized, collected for qualitative analysis, and evaluated for individual risk of bias using the Joanna Briggs Institute's Critical Appraisal Tool. The literature search retrieved 5,186 records; however, only seven studies fulfilled the eligibility criteria and were included. The studies were published between 2002 and 2019. A total of 1,239 restorations were investigated at intervals of 6, 12, 24, and 60 months of follow-up. Some studies had a low risk of bias, while others had moderate and high risk of bias. In general, GIC restorations placed using ART were considered satisfactory. The 6-month, 12-month, and 24-month survival rates ranged from 81.3% to 97.2%, 72.2% to 94%, and 63% to 87%, respectively; additionally, the survival rate for the longest follow-up period (60 months) was 85%. Given the best evidence-based information regarding caries removal, we highlight the need to provide a conservative and effective technique for use in elderly patients. ART is a promising and viable alternative that guarantees the survival of restorations in elderly patients.

Resumo: O estudo buscou investigar a prevalência de trauma dentário em crianças e adolescentes brasileiros. Foi realizada uma revisão sistemática em oito bases de dados: MEDLINE (via PubMed), LILACS, BBO, Scopus, Embase, Web of Science, Open Access Theses and Dissertations e OpenThesis. Foram incluídos apenas estudos de prevalência que usavam métodos de amostragem probabilística, sem limitação de ano ou idioma de publicação. Para avaliar o risco individual de viés, foram utilizadas as ferramentas de avaliação crítica da JBI para estudos de prevalência. Os estudos individuais foram combinados na metanálise com o uso do modelo de efeitos aleatórios. A heterogeneidade entre os estudos foi analisada pelas estatísticas Q de Cochran e I-quadrado. A análise de metarregressão foi realizada para avaliar as fontes de heterogeneidade. A abordagem GRADE avaliou a certeza das evidências entre os estudos incluídos. A busca resultou em 2.069 registros, dos quais 36 foram incluídos no estudo. Os estudos elegíveis foram publicados entre 2000 e 2021, com uma amostra total de 40.194 crianças e adolescentes. A maioria dos estudos (75%) teve baixo risco de viés. Nos dentes permanentes, a prevalência de trauma dentário foi de 21% (IC95%: 16,0; 26,0) e nos dentes decíduos foi de 35% (IC95%: 26,0; 44,0). A prevalência de trauma dentário foi mais alta no sexo masculino que no feminino, para ambas as dentições. Com base na baixa certeza, a prevalência das lesões dentárias traumáticas em crianças e adolescentes brasileiros é mais alta que no resto do mundo, tanto nos dentes decíduos quanto nos permanentes. Além disso, a prevalência de trauma dentário é mais alta em meninos que em meninas.

ABSTRACT BACKGROUND: Elderly men have been characterized as a group vulnerable to suicide, motivated by loneliness, loss of loved ones and feelings of uselessness to family members. OBJECTIVES: To ascertain the prevalence of different mental disorders among elderly men who attempted suicide. DESIGN AND SETTING: Systematic review of observational studies developed as a result of a partnership between two postgraduate schools (Lagarto and Uberlândia). METHODS: An electronic search was performed in eight electronic databases, including “grey literature”, in January 2019. Observational studies that assessed mental disorders among men older than 60 years who attempted suicide were eligible for inclusion. RESULTS: Among the disorders evaluated, mood disorders had the highest prevalence (42.0%; 95% confidence interval, CI: 31.0-74.0%; I2: 0.0%; P = 0.763), followed by substance use-related disorders (41.0%; 95% CI: 8.0-74.0%; I2: 96.4; P < 0.001) and, lastly, schizophrenic disorders (5.0%; 95% CI: 0.0%-14.0%; I2: 80.3%; P = 0.024). CONCLUSIONS: It seems that mood disorders and substance use-related disorders are quite prevalent among elderly men with mental disorders who attempted suicide. It is important to consider the role of healthcare services in making early diagnoses of mental disorders among elderly men, in order to diminish the chances of suicide attempts among them.
