ABSTRACT Biochar can promote crop production and soil quality. However, its characteristics depend on the waste used in its production and its effects may vary according to the species being cultivated and the management adopted. The aim of this study was to evaluate the application of biochar from animal waste on soil quality and the agronomic characteristics of the cowpea. An experiment was set up to test three types of biochar (bovine-BB, swine-SB and poultry-BP), with added fertiliser (BBF, SBF and BPF) and two control treatments, including the addition of calcium magnesium oxide (CT) and calcium magnesium oxide with fertiliser (CTF), giving a total of eight treatments with four replications. There was a respective increase of up to 102.94%, 1048%, 1560% and 360.22% in stem diameter, number of pods, number of grains per pod and stem dry matter from adding the biochar. The poultry biochar increased each of the above parameters even with no added fertiliser. There was no difference in basal soil respiration or β-glucosidase enzyme activity, whereas organic carbon (TOC), total nitrogen (TN), microbial carbon and soil labile carbon were greater with biochar. BBF gave the highest TOC content (24.40 g kg-1), while BP and BPF increased TN by around 61%. The application of biochar + fertiliser contributed to an average reduction of 56% in the soil metabolic quotient. Poultry biochar favoured both the agronomic characteristics of the cowpea and soil quality, while bovine biochar showed more marked results with the addition of fertiliser.

ABSTRACT: Protocols to artificially induce cows and heifers into lactation are effective and commercially available in Brazil. However, these protocols demand long hormonal treatments, which is debatable since little research has been done in the subject. To further understand artificial induction to lactation (AIL) protocols, we conducted two experiments. In experiment 1, our objective was to better characterize steroidal profile during an AIL protocol and assess the estradiol (E2) and progesterone (P4) serum profiles of Jersey cows (n=6) subjected to a conventional protocol. In experiment 2, we aimed to compare milk production and serum E2 concentrations of Holstein heifers induced into lactation by the standard AIL protocol (15 injections of E2 and 8 P4 injections) and by a short protocol in which the number of E2 injections and, consequently, the overall dosage of E2, were reduced (8 injections of E2 and 8 P4 injections). We hypothesized that a short AIL protocol (8 days) would be as efficient as the long standard protocol of 15 days. Our hypothesis was confirmed, since we demonstrated that a shorter protocol was able to induce lactation in Holstein heifers without hindering milk production.

RESUMO: Protocolos que induzem à lactação artificial em vacas e novilhas são eficazes e estão comercialmente disponíveis no Brasil. No entanto, esses protocolos demandam longos tratamentos hormonais, o que é discutível visto que poucas pesquisas foram feitas sobre o assunto. Para entender melhor os protocolos de indução artificial à lactação (IAL), realizamos dois experimentos. Foi testada a hipótese de que um protocolo curto (oito dias) de IAL é tão eficiente quanto o protocolo padrão de 15 dias. No experimento 1 objetivou-se caracterizar o perfil esteroidal durante um protocolo de IAL e avaliou-se os perfis séricos de estradiol (E2) e progesterona (P4) de vacas Jersey (n=6) submetidas a um protocolo convencional. No experimento 2 foram comparadas a produção de leite e as concentrações séricas de E2 de novilhas holandesas induzidas à lactação pelo protocolo padrão de IAL (15 injeções de E2 e 8 injeções de P4) e por um protocolo curto, no qual o número de injeções de E2 e, consequentemente, a dosagem geral de E2 foram reduzidas (oito injeções de E2 e oito injeções de P4). A hipótese foi confirmada, demonstrado que um protocolo mais curto induziu a lactação em novilhas holandesas sem prejudicar a produção de leite.

ABSTRACT Objective: To evaluate symptoms, lung function, and quality of life of a cohort of patients hospitalized for severe COVID-19 12 months after hospital admission. Methods: This was a cross-sectional study. We included severe COVID-19 survivors hospitalized in one of three tertiary referral hospitals for COVID-19 in the city of Belo Horizonte, Brazil. Participants were submitted to lung function and six-minute walk tests and completed the EQ-5D-3L questionnaire. Results: The whole sample comprised 189 COVID-19 survivors (mean age = 59.6 ± 13.4 years) who had been admitted to a ward only (n = 96; 50.8%) or to an ICU (n = 93; 49.2%). At 12 months of follow-up, 43% of patients presented with dyspnea, 27% of whom had a restrictive ventilatory disorder and 18% of whom presented with impaired DLCO. There were no significant differences in FVC, FEV1, and TLC between the survivors with or without dyspnea. However, those who still had dyspnea had significantly more impaired DLCO (14.9% vs. 22.4%; p < 0.020) and poorer quality of life. Conclusions: After one year, survivors of severe COVID-19 in a middle-income country still present with high symptom burden, restrictive ventilatory changes, and loss of quality of life. Ongoing follow-up is needed to characterize long COVID-19 and identify strategies to mitigate its consequences.

ABSTRACT Purpose: The purpose of this study is to assess whether the Dunning-Kruger effect occurs in surgical residents when performing laparoscopic cholecystectomy in a porcine model. Methods: Prospective blinded study, which counted with forty PGY-1 general surgery residents who agreed to participate in the study were blindly recruited to perform a laparoscopic cholecystectomy in a porcine model. At the end of the procedure, the participants assigned a score of 0-10 for their own performance and the video of the operation was independently assessed by 2 experienced laparoscopic surgeons using a validated tool. Results: Participants were divided into groups of 10 individuals according to objective performance and compared. The group with the worst objective result was inferior to the group with the best objective result (3.77 ± 0.44 vs. 8.1 ± 0.44, p < 0.001), but they were similar in self-perception of performance (5.11 ± 1.69 vs. 6.1 ± 1.79, p = 0.999). Conclusions: In the studied sample, it was possible to demonstrate the presence of the Dunning-Kruger effect.

ABSTRACT Objective: To assess Brazilian pediatric intensivists’ general knowledge of extracorporeal membrane oxygenation, including evidence for its use, the national funding model, indications, and complications. Methods: This was a multicenter cross-sectional survey including 45 Brazilian pediatric intensive care units. A convenience sample of 654 intensivists was surveyed regarding their knowledge on managing patients on extracorporeal membrane oxygenation, its indications, complications, funding, and literature evidence. Results: The survey addressed questions regarding the knowledge and experience of pediatric intensivists with extracorporeal membrane oxygenation, including two clinical cases and 6 optional questions about the management of patients on extracorporeal membrane oxygenation. Of the 45 invited centers, 42 (91%) participated in the study, and 412 of 654 (63%) pediatric intensivists responded to the survey. Most pediatric intensive care units were from the Southeast region of Brazil (59.5%), and private/for-profit hospitals represented 28.6% of the participating centers. The average age of respondents was 41.4 (standard deviation 9.1) years, and the majority (77%) were women. Only 12.4% of respondents had taken an extracorporeal membrane oxygenation course. Only 19% of surveyed hospitals have an extracorporeal membrane oxygenation program, and only 27% of intensivists reported having already managed patients on extracorporeal membrane oxygenation. Specific extracorporeal membrane oxygenation management questions were responded to by only 64 physicians (15.5%), who had a fair/good correct response rate (median 63.4%; range 32.8% to 91.9%). Conclusion: Most Brazilian pediatric intensivists demonstrated limited knowledge regarding extracorporeal membrane oxygenation, including its indications and complications. Extracorporeal membrane oxygenation is not yet widely available in Brazil, with few intensivists prepared to manage patients on extracorporeal membrane oxygenation and even fewer intensivists recognizing when to refer patients to extracorporeal membrane oxygenation centers.

Métodos: Este estudo foi um inquérito transversal multicêntrico que incluiu 45 unidades de terapia intensiva pediátrica brasileiras. Realizou-se inquérito de conveniência com 654 intensivistas quanto aos seus conhecimentos sobre manejo de pacientes em oxigenação por membrana extracorpórea, suas indicações, complicações, custeio e evidências bibliográficas. Resultados: O inquérito abordou questões relativas aos conhecimentos e à experiência dos intensivistas pediátricos sobre oxigenação por membrana extracorpórea, incluindo dois casos clínicos e seis questões facultativas sobre o manejo de pacientes em oxigenação por membrana extracorpórea. Dos 45 centros convidados, 42 (91%) participaram do estudo, e 412 (63%) dos 654 intensivistas pediátricos responderam ao inquérito. A maioria das unidades de terapia intensiva pediátrica eram da Região Sudeste do Brasil (59,5%), e os hospitais privados com fins lucrativos representavam 28,6% dos centros participantes. A média de idade dos respondentes era de 41,4 (desvio-padrão de 9,1) anos, e a maioria (77%) era mulher. Apenas 12,4% dos respondentes tinham formação em oxigenação por membrana extracorpórea. Dos hospitais pesquisados, apenas 19% tinham um programa de oxigenação por membrana extracorpórea, e apenas 27% dos intensivistas declararam já ter manejado pacientes em oxigenação por membrana extracorpórea. Apenas 64 médicos (15,5%) responderam a questões específicas sobre o manejo de oxigenação por membrana extracorpórea (mediana 63,4%; oscilando entre 32,8% e 91,9%). Conclusão: A maioria dos intensivistas pediátricos brasileiros demonstrou conhecimentos limitados de oxigenação por membrana extracorpórea, incluindo suas indicações e complicações. A oxigenação por membrana extracorpórea ainda não está amplamente disponível no Brasil, com poucos intensivistas preparados para o manejo de pacientes em oxigenação por membrana extracorpórea e ainda menos intensivistas capazes de reconhecer quando devem encaminhar pacientes para centros de oxigenação por membrana extracorpórea.

ABSTRACT Introduction: Inguinal hernia and varicocele are common conditions in male population. Laparoscopy brings the opportunity to treat them simultaneously, through the same incision. However, there are different opinions about the risks for testicular perfusion of multiple procedures in the inguinal region. In this study, we assessed the feasibility of simultaneous laparoscopic procedures by studying clinical and surgical outcomes of patients undergoing bilateral inguinal hernioplasty using the transabdominal preperitoneal (TAPP) technique with and without concomitant bilateral laparoscopic varicocelectomy (VLB). Methods: a sample of 20 patients from the University Hospital of USP-SP with indirect inguinal hernia and varicocele with indication for surgical correction was selected. Patients were randomized into two groups, 10 undergoing TAPP (Group I) and 10 undergoing simultaneous TAPP and VLB (Group II). Data regarding total operative time, complications and postoperative pain was gathered and analyzed. Results: there was no statistical difference between groups regarding total operative time and postoperative pain. Only one complication (spermatic cord hematoma) was observed in Group I and no complications were observed in Group II. Conclusions: simultaneous TAPP and VLB in was shown to be effective and safe, which provides a basis for conducting studies on larger scales.

RESUMO Introdução: hérnia inguinal e varicocele são doenças comuns na população masculina. O advento da laparoscopia traz a oportunidade de tratá-las simultaneamente, pelo mesmo acesso. Entretanto, existem divergências sobre os riscos para a perfusão testicular de múltiplos procedimentos na região inguinal. Neste estudo, avaliamos a viabilidade de procedimentos laparoscópicos simultâneos estudando resultados clínicos e cirúrgicos de pacientes submetidos à hernioplastia inguinal bilateral pela técnica transabdominal préperitoneal (TAPP) com e sem varicocelectomia laparoscópica bilateral (VLB) concomitante. Métodos: uma amostra de 20 pacientes do Hospital Universitário da USP-SP com hérnia inguinal indireta e varicocele com indicação de correção cirúrgica foi selecionada. Os pacientes foram randomizados em dois grupos, sendo 10 submetidos à TAPP (Grupo I) e 10 submetidos à TAPP e VLB simultâneas (Grupo II). O tempo operatório total, complicações e dor pós-operatória foram coletados e analisados. Resultados: não houve diferença estatística entre os grupos com relação ao tempo operatório total e à dor pós-operatória. Apenas uma complicação (hematoma do cordão espermático) foi observada no Grupo I e não foram observadas complicações no Grupo II. Conclusões: no mesmo procedimento, submeter pacientes à TAPP e à VLB no mesmo procedimento se mostrou eficaz e seguro, o que fornece embasamento para a realização de estudos em maiores escalas.

Abstract The objective of this study was to evaluate the effect of filter cake biochar on the chemical and microbiological attributes of a dystrophic red-yellow latosol cultivated with macaúba (Acrocomia aculeata), araçá (Psidium firmum) and cajuzinho do cerrado (Anacardium humile), species native to the Cerrado. Thus, the responses of soil attributes were evaluated 120 days after transplanting the seedlings using four doses of biochar (1%, 2%, 4% and 8% v/v) and two control treatments (one with soil correction and fertilization and the other with no fertilization). The attributes evaluated were pH, contents of calcium, magnesium, phosphorus, potassium, CTC, total and microbial organic carbon and nitrogen, and C:N ratio. For the soils cultivated with the three Cerrado species, the 1% dose of biochar and mineral fertilization were the treatments that best conditioned the soil during the cultivation period and promoted a better response of the chemical and microbiological attributes of the soil. redyellow red yellow Acrocomia aculeata, aculeata , aculeata) Psidium firmum Anacardium humile, humile humile) Thus 12 1%, 1 (1% 2 2% 4 8 v/v vv v one fertilization. . fertilization) pH calcium magnesium phosphorus potassium CTC nitrogen CN C N ratio (1 (

ABSTRACT Varicocele occurs in 15% of general male population and in 35% of infertile men. Since 1992, surgical correction with laparoscopic varicocelectomy is the gold standard for treatment of symptomatic patients or patients with abnormal seminal analysis. The learning curve for this frequently performed procedure has not yet been described. In the present study, we investigated the learning curve of a single urologist in training performing his first 21 laparoscopic varicocelectomies using qualitative and quantitative tools to evaluate his performance during the process. Our results show that 14 bilateral laparoscopic varicocelectomies are enough to achieve the plateau of the learning curve. 15 35 men 1992 analysis described study 2 process 1 3 199 19

RESUMO Varicocele ocorre em 15% dos homens e em 35% dos homens inférteis. Desde 1992, a correção cirúrgica com varicocelectomia laparoscópica é o padrão ouro para o tratamento de pacientes sintomáticos ou com análise seminal anormal. A curva de aprendizado para esse procedimento frequentemente realizado ainda não foi descrita. No presente estudo, investigamos a curva de aprendizado de um único urologista em treinamento realizando suas primeiras 21 varicocelectomias laparoscópicas usando ferramentas qualitativas e quantitativas para avaliar seu desempenho durante o processo. Nossos resultados mostram que 14 varicocelectomias laparoscópicas bilaterais são suficientes para atingir o platô da curva de aprendizado. 15 35 inférteis 1992 anormal descrita estudo 2 processo 1 3 199 19

ABSTRACT Objective: To describe the functional results, recurrence rate, postoperative radiographic appearance, and complications of patients undergoing the Latarjet procedure over 24 months. Methods: Retrospective case series, including adult patients with recurrent traumatic anterior glenohumeral dislocation undergoing the Latarjet procedure. We clinically evaluated patients preoperatively by the Rowe score and at six, 12, and 24 months after the procedure. The positioning, consolidation, and resorption of the graft were analyzed by plain radiography. The recurrence rates and other complications were also described. Results: We analyzed 40 patients (41 shoulders). The Rowe score median increased from 25 before surgery to 95 at 24 months after surgery (p < 0.001). We observed graft resorption in three cases (7.3%) and consolidation in 39 (95.1%). Most grafts presented adequate placement. We observed two recurrences (4.8%), one case of dislocation and one of subluxation. Seven patients (17.1%) had a positive apprehension test. The study had no cases of infection, neuropraxia, or graft breakage. Conclusion: Latarjet surgery is a safe and effective procedure in the treatment of recurrent anterior dislocation of the shoulder. This surgery enables a statistically significant improvement according to the Rowe score, with a low number of recurrences. Level of Evidence IV, Case Series.

RESUMO Objetivo: Descrever os resultados funcionais, a taxa de recidiva, o aspecto radiográfico pós-operatório e as complicações de pacientes submetidos ao procedimento de Latarjet ao longo de 24 meses. Métodos: Série de casos retrospectiva que inclui pacientes adultos com luxação glenoumeral recidivante anterior traumática submetidos ao procedimento de Latarjet. Avaliamos clinicamente os pacientes pela escala de Rowe pré-operatória e aos 6, 12 e 24 meses após o procedimento. O posicionamento, a consolidação e a reabsorção do enxerto foram analisados por radiografia simples. Descrevemos ainda as taxas de recidiva e as demais complicações. Resultados: Analisamos 40 pacientes (41 ombros). A mediana da escala de Rowe evoluiu de 25,0 antes da cirurgia para 95,0 passados 24 meses desde a cirurgia (p < 0,001). Foi observada reabsorção do enxerto em três casos (7,3%), e consolidação em 39 (95,1%). A maioria dos enxertos apresentava posicionamento adequado. Ocorreram duas recidivas (4,8%), sendo um caso de luxação e outro de subluxação. Sete pacientes (17,1%) referiam sensação de apreensão. Não ocorreram casos de infecção, neuropraxia ou quebra do enxerto. Conclusão: A cirurgia de Latarjet é um procedimento seguro e eficaz no tratamento da luxação anterior recidivante do ombro, possibilitando melhora funcional significativa de acordo com a escala de Rowe, com baixo número de recidivas.

Abstract Introduction Return to sport is a desired outcome in individuals submitted to anterior cruciate ligament reconstruction (ACLR). Objective Understand the factors that affect return to pre-injury level sport after ACLR from the patient’s perspective. Methods The sample consisted of 29 individuals submitted to ACLR who participated in sport before the ligament injury. This is a narrative analysis with a qualitative approach, using a semi-structured interview as a methodological resource. Standardized instruments were also applied to evaluate psychological readiness to return to sport, via the Anterior Cruciate Ligament – Return to Sport after Injury Scale (ACL-RSI); self-perceived knee function using the International Knee Documentation Committee (IKDC) subjective questionnaire; and the frequency of participation in sports with the Marx scale. Results Analysis of the interviews produced three main themes related to post-ACLR return to sport: self-discipline, fear of reinjury and social support. In qualitative analysis, the average scores obtained were 59.17 (± 23.22) on the ACL-RSI scale, 78.16 (± 19.03) for the IKDC questionnaire and 9.62 (± 4.73) and 7.86 (± 5.44) for the Marx scale before and after surgery, respectively. Conclusion: Psychological factors influence the decision to return to sport post-ACLR. Physiotherapists should therefore be aware of the psychological aspects and expectations of patients, and that other health professionals may be needed to help prepare these individuals to return to their preinjury sports level and achieve more satisfactory outcomes after ACLR. .

Resumo Introdução O retorno ao esporte é um desfecho alme-jado pelos indivíduos que se submetem à reconstrução do ligamento cruzado anterior (RLCA). Objetivo Com-preender os fatores que interferem no retorno ao esporte no nível anterior à lesão ligamentar em indivíduos submetidos à RLCA sob o ponto de vista do paciente. Métodos A amostra foi composta por 29 indivíduos que se submeteram à RLCA e praticavam esporte antes da lesão ligamentar. O estudo é caracterizado como uma pesquisa narrativa de abordagem qualitativa, utilizando como recurso metodológico a entrevista semiestrutu-rada. Com o uso de instrumentos padronizados, avaliou-se também a prontidão psicológica para retornar ao esporte, utilizando a escala ACL-RSI; a autopercepção da função do joelho, utilizando o questionário subjetivo do IKDC; e a frequência de participação esportiva antes da lesão e após a cirurgia, utilizando a Escala de Marx. Resultados A análise das entrevistas gerou três unidades temáticas principais relacionadas com o retorno ao esporte pós-RLCA: autodisciplina, medo de uma nova lesão e suporte social. Na análise quantitativa, obteve-se média de 59,17 pontos (± 23,22) na escala ACL-RSI, 78,16 pontos (± 19,03) no IKDC, e 9,62 (± 4,73) e 7,86 pontos (± 5,44) na escala de Marx, antes da lesão e após a cirurgia, respectivamente. Conclusão Fatores psicológicos influenciam a decisão de retorno ao esporte pós-RLCA. Os fisioterapeutas, portanto, devem estar atentos aos aspectos psicológicos e expectativas dos pacientes, considerando a necessidade de outros profissionais da saúde auxiliarem na preparação do indivíduo para retornar ao nível esportivo pré-lesão e alcançar resultados mais satisfatórios pós-RLCA. almejado alme jado RLCA. .

ABSTRACT Objective: This study compared mandibular growth in children, aged 7 to 12 years, with Class II malocclusion and normal occlusion, between the following stages of cervical vertebrae maturation: initiation (I), acceleration (A), transition (T). Material and Methods: A total of 148 lateral cephalograms (78 males, 70 females) of Class II malocclusion patients, and 60 lateral cephalograms (30 males, 30 females) of normal occlusion patients were included. The following linear cephalometric measurements were performed: Co-Gn (effective mandibular length), Co-Go (ramus height), and Go-Gn (length of mandibular body). Mean values of increments between stages (I-A, A-T, I-T) were obtained for each group and gender. Results were compared using the Student t-test, and a significance level of 0.05% was adopted. Results: Females group: A-T interval presented a greater increment in Co-Go in the Class II group, which was not significant for the I-T interval, with numerically smaller increments in Co-Gn and Go-Gn, without statistical significance. Males group: intervals I-A, A-T and I-T showed numerically smaller growth increments in the Class II group, with statistical significance for Co-Gn in I-A (p=0.001) and I-T (p=0.003). Comparing genders of the Class II group, Co-Go was higher in males (p=0.002) and I-T interval (p=0.031). In the Normal Occlusion group, the male gender had the greatest Co-Gn (p=0.038) for the I-A interval. In A-T and I-T, Co-Go in males was higher, with statistical significance (p=0.000 and p=0.002, respectively). Conclusion: Growth phenomenon affects the mandibular dimensions regardless of the character of the malocclusion, with a tendency to be smaller in the presence of Class II malocclusion.

RESUMO Objetivo: Esse estudo comparou o crescimento mandibular em crianças de 7 a 12 anos de idade, com má oclusão de Classe II ou Oclusão Normal, entre os seguintes estágios de maturação das vértebras cervicais: iniciação (I), aceleração (A), transição (T). Material e Métodos: No total, 148 telerradiografias laterais (78 meninos, 70 meninas) de pacientes com má oclusão de Classe II e 60 telerradiografias laterais (30 meninos, 30 meninas) de pacientes com Oclusão Normal foram avaliadas. As medidas cefalométricas lineares Co-Gn (comprimento mandibular efetivo), Co-Go (altura do ramo mandibular) e Go-Gn (comprimento do corpo mandibular) foram analisadas e os valores médios dos incrementos entre os estágios (I-A, A-T e I-T) foram obtidos para cada grupo e sexo. Resultados: Os resultados foram comparados pelo teste t de Student, e o nível de significância adotado foi de 0,05%. Sexo feminino: houve maior incremento na altura do ramo no grupo Classe II em A-T, que diminuiu em I-T, com menores incrementos no comprimento mandibular efetivo e no corpo mandibular, sem significância estatística. Para o sexo masculino, nos intervalos I-A, A-T, I-T, os incrementos de crescimento foram numericamente menores no grupo Classe II, com significância estatística para o comprimento efetivo da mandíbula em I-A (p= 0,001) e em I-T (p= 0,003). No grupo Classe II, a altura do ramo foi maior para o sexo masculino (p= 0,002) e no intervalo I-T (p= 0,031). No grupo Oclusão Normal, o sexo masculino apresentou o maior comprimento mandibular efetivo (p= 0,038) no intervalo I-A. Nos intervalos A-T e I-T, a altura do ramo mandibular no sexo masculino foi maior e com significância estatística de p= 0,000 e p= 0,002, respectivamente. Conclusão: O fenômeno do crescimento afeta as dimensões mandibulares independentemente do característica da má oclusão, com tendência a ser menor na presença da má oclusão de Classe II.

ABSTRACT Objective: To describe a protocol of obtention of mesenchymal stem cells and to report their use as a biological adjuvant in three patients undergoing arthroscopic rotator cuff repair. Methods: Case series of patients who underwent arthroscopic repair of isolated full-thickness supraspinatus tear using mesenchymal stem cells obtained from the bone marrow as a biological adjuvant. All patients were operated on at the same institution, by a surgeon with 13 years of experience. The cells were applied at the end of the procedure, at the tendon-bone interface, at an approximate concentration of 2,000,000 mesenchymal cells/mm3 and a total volume of 5 ml. Results: All patients improved with the procedure, with one excellent and two good results. All cases overcame the minimally important clinical difference. All cases reached tendon healing, without partial or complete re-tears. We observed no complications. Conclusion: Arthroscopic rotator cuff repair with added mesenchymal cells obtained from bone marrow and submitted to a cell expansion process led to good functional results and healing in all cases in the sample, with no complications.

Abstract This exploratory study investigated whether children with dental decay were more likely to have COVID-19 than those without caries. The children underwent dental inspection and blood collection for detection of SARS-CoV-2 antibodies. Fifty-four children aged 6 to 9 years participated in the survey, which was conducted between March and June 2020 in the municipality of Ipojuca, Pernambuco, Brazil. The diagnosis of caries was performed using the dmft and DMFT indices. Parents reported signs and symptoms of sickness in their children during this period. The serology test aimed to verify the immune response of the children to coronavirus by detecting IgM/IgG antibodies. Statistical analyses were performed at P < 0.05. The majority of the children presented caries (68.5%). Of the nine children who tested positive for COVID-19 (16.7%), eight presented IgG antibodies to the virus, and only one had IgG and IgM antibodies to SARS-CoV2. Children who tested positive for SARS-CoV-2 had a higher percentage of caries lesions than those who tested negative for SARS-CoV-2 (77.8% vs 65.9%), but this difference was not statistically significant.
