A prática do kitesurf no litoral piauiense e suas implicações sobre este patrimônio natural / The practice of kitesurfing on the coast of piauí and its implications on this natural heritage

Considerado patrimônio natural, o litoral piauiense é referência nacional e internacional para o Kitesurf, esporte na natureza pouco estudado, embora conste em pesquisas sobre desenvolvimento turístico na região. Este artigo analisa implicações da prática do Kitesurf nesse litoral e identifica ações que podem contribuir para sua conservação. Realizou-se pesquisa qualitativa, exploratória, mediante pesquisa bibliográfica e documental. Em certas praias há conflitos entre kitesurfista, pescador e/ou banhista; além da prática oferecer riscos para animais silvestres. Todavia, há kitesurfista que recolhe lixo no mar e promove discussões sobre efeitos do esporte na região. Abordar a educação ambiental em clínicas de certificação de kitesurfistas e regulamentar o Kitesurf pode colaborar com a resolução de conflitos e perspectivar um turismo mais sustentável, almejando conservar esse patrimônio e suas potencialidades.

The coast of Piauí, considered a natural heritage, is a national and international reference for kitesurfing, sport in naturelittle studied, although it is part of research on the regional tourism development. This article analyzes the implications of the practice of kitesurfing on this coast and identifies actions that can contribute to its conservation. Qualitative, exploratory research was carried out through bibliographical and documentary research. On certain beaches there are conflicts between kitesurfers, fishermen and/ or bathers; in addition, its practice offers risks to wild animals. However, there are kitesurfers who collects garbage at sea and promotes discussions about the effects of the sport in the region. Addressing environmental education of kitesurfers in certification clinics and regulating kitesurfing can collaborate with conflict resolution and envisage a more sustainable tourism, aiming to conserve this heritage and its potential.

Pista direta planas para tratamento de mordida cruzada anterior funcional ­ relato de caso / Planas direct track for functional anterior crossbite treatment ­ case report

Resumo A mordida cruzada anterior é uma má oclusão frequentemente observada nas dentições decídua e mista, pode ser classificada em dentária, esquelética ou funcional. Esta última, quando interceptada de forma precoce, pode apresentar um prognóstico satisfatório. Nesse contexto, a confecção de pistas diretas Planas têm se mostrado uma alternativa eficiente, quando poucos elementos dentários são envolvidos. Este trabalho apresenta o caso clínico de um paciente de 6 anos de idade, portador de mordida cruzada anterior unilateral do tipo funcional, cujo diagnóstico diferencial e intervenção precoce permitiram a resolução do caso. Ao manipular a mandíbula, levando os côndilos em relação cêntrica (RC), notou-se a presença de interferência oclusal entre os caninos decíduos superior e inferior do lado direito, que são as causas da anteriorização da mandíbula, com oclusão em MIH. Para correção, utilizou-se terapia de pista direta Planas confeccionada sob canino superior direito em resina composta e leve desgaste no canino inferior do lado direito. Os contatos prematuros foram removidos, criando um plano inclinado de aproximadamente 45 graus na face palatina do canino superior e um leve ajuste oclusal na face incisal do canino inferior do lado direito. O uso dessa técnica permitiu a correção da mordida cruzada anterior funcional imediatamente após a remoção da interferência oclusal. O caso relatado demonstra que o tratamento precoce de mordidas cruzadas propicia maiores chances de sucesso na reabilitação do sistema estomatognático. A utilização de pistas diretas Planas demonstrou ser uma alternativa eficaz, de baixo custo e de fácil execução para tratamento de mordidas cruzadas funcionais. (AU)

Abstract Anterior crossbite is a malocclusion frequently found in deciduous and mixed dentitions, it can be classified as dental, skeletal or functional. This last one has a favorable prognosis when the treatment occurs in early stages. Considering this, Planas direct tracks have been showing to be an effective and less invasive alternative when few dental elements are involved. This paper presents a clinical case of a 6-year-old patient with functional unilateral anterior crossbite whose differentiated diagnosis and early intervention allowed a successful treatment. By manipulating the jaw and positioning the condyles in centric relation (CR), the presence of occlusal interference between the upper and lower deciduous canines on the right side was noticed, which are the causes of mandible anterior displacement with occlusion in MIH. For correction, Planas direct track therapy was used on the upper right canine with composite resin followed by slight wear on the lower right canine. The premature contacts were eliminated, creating an inclined plane of approximately 45 degrees on the palatal face of the upper canine and a slight occlusal adjustment on the incisal surface of the lower right canine. The use of this technique allowed the correction of the functional anterior crossbite immediately after the removal of the occlusal interference. This case shows that the early treatment of crossbites increases the chances of a successful rehabilitation of stomatognathic system. The use of Planas direct tracks proved to be an effective, low-cost, and easy to implement alternative for functional crossbites correction. (AU)

Association of taste receptor gene polymorphisms with dental caries.

This study was performed to evaluate the interplay between dental caries, nutritional status, and genetic polymorphisms in TAS1R1 and TAS1R2 (taste receptor, type 1, member 1 and 2) in preschool children and pre-adolescents. We included 525 subjects (306 preschool children and 219 pre-adolescents). Parents/caregivers answered a self-administered questionnaire about their children's systemic health, characteristics, oral hygiene habits, and diet. Clinical examination was performed to evaluate dental caries and nutritional status. Saliva samples were collected for DNA extraction. The genotyping of rs17492553 ( TAS1R1 ), rs3935570, and rs4920566 ( TAS1R2 ) polymorphisms was performed using real-time PCR with Taqman Genotyping Master Mix and SNP assay. Both univariate and multivariate Poisson regression analyses with robust variance were used for the data analysis. In preschool children, consumption of sweets between meals increased the prevalence of dental caries by 85% (PR c = 1.85; 95%CI 1.39-2.46; p < 0.001), whereas in pre-adolescents, this prevalence increased by 34% (PR a = 1.34; 95%CI 1.11-1.62; p = 0.002), regardless of genetic polymorphisms . Moreover, individuals carrying at least one allele C in rs17492553 presented 23% more prevalence of dental caries (PR a = 1.23; 95%CI 1.02-1.49 p = 0.030). Nutritional status was not associated with dental caries, neither with genetic polymorphisms . Consumption of sweets between meals increased the prevalence of dental caries. In pre-adolescents, rs17492553 genetic polymorphism in TAS1R1 was associated with dental caries.

Metastatic Biphasic Primitive Tumor in the Mandible of a Child.

Pediatric mandibular tumors present an aggressive biological behavior and difficult diagnosis. A wide range of odontogenic and nonodontogenic tumors comprise the spectrum of these lesions. We report a case of a 1-year-old male child patient showing facial asymmetry symptomatic of an expansive lesion extending throughout the body and ramus of the left hemimandible with a diameter of 8 cm. The histopathological report suggested a high-grade mucoepidermoid carcinoma (MEC), recommending further immunohistochemical investigation of the ectomesenchymal or neuroectodermal origin of the tumor cells. The patient evolved with extensive bilateral pleural effusion followed by metastasis in the middle third of the right humerus, and died 2 months after the first biopsy procedure by acute renal failure with tubular necrosis, before a final inconclusive immunohistochemical report was reached. The lack of resources for less-favored regions of Brazil impairs rapid biomolecular examinations such as immunohistochemical resulting in delay of appropriate therapeutic procedures.

Assessing the Association between Dental Caries and Nutritional Status in Children from the Brazilian State of Amazonas.

AIM: To evaluate the association between dental caries and nutritional status in a group of Brazilian schoolchildren, from Manaus. The studied population consisted of 197 students (10-12-year-olds) from public schools at Manaus, Amazonas, Brazil. MATERIALS AND METHODS: A clinical examination was carried out and the decay-missing-filled-teeth index for primary and permanent teeth (dmft and DMFT) was used to evaluate dental caries. Body mass index Z-score was calculated using variables such as individual height, weight, age, and gender. The nutritional status was classified as underweight, eutrophic, overweight, and obese. One-way ANOVA and Tukey's posttests were used for means' comparison between groups. The established alpha was 5%. RESULTS: Eighty-one (41.1%) children were caries-free. Five (2.5%) children were underweight; 127 (64.5%) were eutrophic; 49 (24.9%) were overweight; and 16 (8.1%) were obese. The mean dmft/DMFT index was 1.67 (2.05). Obese children had more caries experience than eutrophic and overweight children (p < 0.05). CONCLUSION: Our study demonstrated that dental caries is associated with obesity in school children from Manaus. HOW TO CITE THIS ARTICLE: Vasconcelos K, Evangelista S, et al.

MMP13 Contributes to Dental Caries Associated with Developmental Defects of Enamel.

The aim of this study was to investigate the association between genetic polymorphisms in MMP8, MMP13, and MMP20 with caries experience and developmental defects of enamel (DDE) in children from the Amazon region of Brazil. Den tal caries and DDE data were collected through clinical examination from 216 children. Genomic DNA was extracted from saliva, and genotyping of selected polymorphisms in MMP8 (rs17099443 and rs3765620), MMP13 (rs478927 and rs2252070), and MMP20 (rs1784418) was performed using TaqMan chemistry and endpoint analysis. χ2 or Fisher's exact tests were used to compare allele and genotype distributions between children with caries experience and caries-free children and between DDE-affected and -unaffected children with an established alpha of 5%. The polymorphism rs478927 in MMP13 was associated with caries experience and DDE (p < 0.05). The analysis performed comparing children with both conditions (caries experience plus DDE) and children with neither of the conditions (caries-free chil dren without DDE) demonstrated that children carrying the MMP13 rs478927 TT genotype were more likely to have concomitant occurrence of these two conditions (OR = 5.8, 95% CI 2.1-15.8; p = 0.0003). In conclusion, the genetic polymorphism rs478927 in MMP13 was associated with caries experience and DDE.

Knowledge of parents/caregivers about the sleep bruxism of their children from all five Brazilian regions: A multicenter study.

BACKGROUND: Sleep bruxism (SB) is a masticatory muscle activity that affects children. Parents' knowledge is important for its identification and report to dentists. AIM: To investigate parents' knowledge about SB among their children. DESIGN: A cross-sectional study included 1325 parents of children from dental clinics of seven institutions from all regions of Brazil. Parents answered questions about child's sleep, knowledge about SB and its occurrence among children and parents. SB definition given by parents was dichotomized as "correct"/"incorrect", based on the American Academy of Sleep Medicine definition. Descriptive, bivariate and multivariate analyses were performed (P < 0.05). RESULTS: Most parents (57.3%) did not know what SB is and 88.9% would like to receive more information. SB prevalence among parents was 15.4% and 24.0% among children. Between parents who correctly defined SB, its prevalence increased to 27.5% among parents and 40.6% among children. Parents whose children had/have SB, who would like to receive more information about SB and were from the North, Central-West, Southeast, and South regions were more likely to define SB correctly (P > 0.05). CONCLUSION: There is a lack of knowledge of parents about SB. SB among children, parents' interest in receiving more information and their location were factors associated to their knowledge.

Oestrogen receptor alpha, growth hormone receptor, and developmental defect of enamel.

BACKGROUND: Oestrogen (ES) and growth hormone (GH) are hormones that may have a role in caries aetiology and developmental defects of enamel (DDE) since their receptors (ERs and GHR) are expressed during amelogenesis. AIM: To evaluate whether genetic polymorphisms in the genes that codify the ERα (ESR1) and GHR are associated with caries experience and DDE in children. DESIGN: Two hundred and sixteen children of both genders, aged 9-12 years, were examined and classified according to caries and DDE phenotype. Genomic DNA was extracted from buccal cells in saliva. Genetic polymorphisms in ERS1 (rs1884051 and rs12154178) and GHR (rs297305, rs2940913, rs2910875, and rs1509460) were genotyped using TaqMan chemistry. Data were analysed by PLINK, while the chi-square test was used to compare allele and genotype distributions (alpha of 5%). RESULTS: A total of 131 children (60.7%) had caries experience, and 43 (19.9%) presented DDE. Genotype and allele distributions were not associated with caries experience (P > 0.05). Genotype and allele distributions between DDE, affected and unaffected, were associated with the polymorphism rs12154178 in ESR1 (P = 0.01 and P = 0.001, respectively) and with the polymorphism rs1509460 in GHR (P = 0.05 and P = 0.02, respectively). CONCLUSIONS: Genetic polymorphisms in ERS1 (rs12154178) and GHR (rs1509460) are associated with DDE.

Development and characterization of a novel bulk-fill elastomeric temporary restorative composite.

OBJECTIVES: This study investigated the physical and mechanical properties, antibacterial effect and biocompatibility of novel elastomeric temporary resin-based filling materials (TFMs) containing zinc methacrylate (ZM). MATERIAL AND METHODS: Experimental TFMs were prepared by mixing the zinc methacrylate with monomer, co-monomer, photoinitiator and fillers. A ZM concentration of 0 (control), 0.5% (Z0.5); 1% (Z1), 2% (Z2), or 5% (ZM5) wt% was added to the TFMs. Fermit-N (F) was used for comparison with the experimental material. Microleakage, water sorption/solubility, degree of conversion, depth of cure, ultimate tensile strength, and hardness were determined and compared. A modified direct contact test (DCT) with Enterococcus faecalis and a Streptococcus mutans' biofilm accumulation assay was carried out to evaluate the antimicrobial effect and cytotoxicity of the assay. Statistical comparisons were performed (α=5%). RESULTS: The results showed that the physical and mechanical properties of the experimental TFMs with ZM are comparable with the properties of the commercial reference and some properties were improved, such as lower microleakage and water sorption, and higher ultimate tensile strength values. TFMs with ZM killed E. faecalis only after 1 h. Biofilm development of S. mutans was not affected by the inclusion of ZM in the experimental TFMs. CONCLUSIONS: The present findings suggest that the physical, mechanical and biological properties of the experimental TFMs with ZM are comparable with the properties of the commercial reference. However, some properties were improved, such as lower microleakage and water sorption, and higher ultimate tensile strength values.

Timing of Permanent Tooth Emergence is Associated with Overweight/Obesity in Children from the Amazon Region.

The aim of this study was to evaluate the association between timing of permanent tooth emergence with overweight and obesity in children from Brazilian Amazon region. The studied population consisted of 192 children, 09 to 12 year-old, from public schools at Manaus, Amazonas-Brazil. Clinical examination was performed and the tooth emergence was evaluated according to the number of permanent erupted teeth. Body mass index z-score was calculated. For the statistical analysis 'Overweight/obese' group was compared with 'Normal weight' group in a case to control ratio 1:2. The t-test based on age was used for means comparison between the groups. A linear regression analysis using age and gender as co-variants was used. The established alpha was 5%. One hundred twenty-seven children were classified as normal weight and 65 were classified as overweight/obese (49 were overweight and 16 were obese). Overweight/obesity condition was associated with the gender, in which boys had a higher chance to present higher weight conditions (OR=1.84; CI 95% 1.06-3.37; p=0.04). The mean number of permanent teeth was higher in the overweight/obesity group (p<0.001). Linear regression analysis demonstrated that nutritional status, gender and age were strongly associated with number of permanent erupted teeth (p<0.05). In conclusion, our study demonstrated that timing of permanent tooth emergence is associated with overweigh/obesity in children from Manaus, Brazil.

A população estudada foi composta por 192 crianças, de 9 a 12 anos, de escolas públicas de Manaus, Amazonas-Brasil. O exame clínico foi realizado e a erupção dentária foi avaliada de acordo com o número de dentes permanentes irrompidos. O índice de massa corporal escore-z foi calculado. Para a análise estatística, comparou-se o grupo "sobrepeso / obesidade" com o grupo "peso normal" em uma proporção de controle 1: 2. O teste t baseado na idade foi utilizado para comparação das médias entre os grupos. Uma análise de regressão linear usando idade e sexo como co-variáveis foi utilizada. O alfa estabelecido foi de 5%. Cento e vinte e sete crianças foram classificadas com peso normal e 65 foram classificados com sobrepeso / obesidade (49 com sobrepeso e 16 com obesidade). A condição de sobrepeso / obesidade associou-se ao gênero, no qual os meninos tiveram maior chance de apresentar condições de maior peso (OR = 1,84; IC 95% 1,06-3,37; p = 0,04). O número médio de dentes permanentes irrompidos foi maior no grupo sobrepeso / obesidade (p <0,001). A análise de regressão linear demonstrou que o estado nutricional, sexo e idade foram fortemente associados ao número de dentes permanentes irrompidos (p <0,05). Concluindo, nosso estudo demonstrou que o momento da erupção dos dentes permanentes é associado com sobrepeso / obesidade em crianças de Manaus, Brasil.

Evaluation of physical-mechanical properties, antibacterial effect, and cytotoxicity of temporary restorative materials.

The objective of this study was to compare selective physical-mechanical properties, antibacterial effects and cytotoxicity of seven temporary restorative materials (TRM): five resin-based materials [Bioplic (B), Fill Magic Tempo (FM), Fermit inlay (F), Luxatemp LC (L) and Revotek LC (R)], and zinc oxide-eugenol cement (IRM) and glass ionomer cement (GIC) as the controls. Material and methods The physical-mechanical properties were evaluated by determining microleakage (ML), ultimate tensile strength (UTS) and Shore D hardness (SDH). In addition, the polymerization rate (Pr-1), depth of cure (DC), water sorption and solubility (WS/SL) were evaluated. The antimicrobial effects of the materials were assessed by biofilm accumulation of Streptococcus mutans (BT) and the direct contact test (DCT) by exposure to Enterococcus faecalis for 1 and 24 h, and cytotoxicity by MTT assay. The data were analyzed by ANOVA or Kruskall-Wallis tests, and a complementary post-hoc method (p<0.05). Results Group B, followed by FM and GIC had significantly lower percentages of microleakage in comparison with the other groups; Groups FM and L showed the highest WS, while Groups R and FM showed the significantly lowest SL values (p<0.05). Group R showed the statistically highest UTS mean and the lowest DC mean among all groups. Group F showed the lowest S. mutans biofilm accumulation (p=0.023). Only the Group L showed continued effect against E. faecalis after 1 h and 24 h in DCT. The L showed statistically lower viability cell when compared to the other groups. Conclusions These findings suggest the antibacterial effect of the temporary materials Fill Magic and Bioplic against S. mutans, while Luxatemp showed in vitro inhibition of S. mutans biofilm accumulation and E. faecalis growth. Regarding the cell viability test, Luxatemp was the most cytotoxic and Fill Magic was shown to be the least cytotoxic.

Luxação extrusiva de um incisivo central Permanente jovem: relato de caso clínico / Extrusive luxation of an immature permanent central incisor: clinical case report

Objetivo: O objetivo deste artigo é apresentar o relato de um caso clínico de luxação extrusiva de dente permanente com rizogênese incompleta, onde não foi necessária a realização de intervenção endodôntica. Relato de caso: Paciente de 6 anos de idade compareceu ao serviço de urgência da Policlínica Odontológica da Universidade do Estado do Amazonas (UEA) para atendimento após queda durante atividade de lazer, apresentando traumatismo direto na boca. Foi informado durante a consulta inicial que o incidente havia ocorrido há cerca de três dias, e que o atendimento imediato logo após o trauma foi realizado em um Serviço de Pronto Atendimento, porém, nenhum tipo de procedimento na cavidade oral foi realizado. Após exames clínico e radiográfico observou-se que o dente 21 apresentava deslocamento parcial para fora do alvéolo dentário no sentido axial, com alteração da oclusão, dor local à palpação e mobilidade dentária. Foi realizada profilaxia da área afetada, e anestesia do dente luxado e tecidos adjacentes. O reposicionamento do dente foi realizado em seguida, pressionando-o e tracionando-o de forma suave e contínua até a sua correta posição dentro do alvéolo. A área afetada foi limpa com gaze estéril embebida em soro fisiológico, e foi instalada uma contenção rígida confeccionada com fio ortodôntico e resina composta. Conclusão: O reposicionamento da maneira adequada do dente traumatizado dentro do alvéolo dentário, num período de tempo hábil, seguido de sua proservação, permitiram a manutenção da vitalidade do tecido pulpar, e consequentemente, o desenvolvimento do segmento radicular.

Objective: The objective of this article is to present a clinical case of extrusive luxation of an immature permanent tooth, with no endodontic management. Case report: A 6-year-old patient was provided to emergency treatment at the State University of Amazonas, as a result of a fall, with a direct trauma to the mouth. It was informed during the initial consultation that the incidente has occurred three days after. Emergency examination had been carried out by an Emergency Service; however, any type of procedure in the oral cavity was performed in ths occasion. After clinical and radiographic examinations, it was observed that tooth 21 presented partial displacement from the alveolar socket in the axial direction, with occlusion alteration, local pain to palpation and dental mobility. Cleaning of the affected area and anesthesia of the dislocated tooth and adjacent tissues were performed. Then, tooth repositioning was performed by pressing and tracing it smoothly and continuously until its correct position within the alveolar socket. The affected area was cleaned with sterile gauze soaked in saline solution, and a rigid containment made of orthodontic wire and composite resin was installed. Conclusion: A proper repositioning of the traumatized tooth within the alveolar socket, followed by its clinical followup, allowed the pulp tissue to remain vital, and consequently, the complete development of the root portion

In this way, its use will help the professionals of this segment, as long as no specific and more detailed legislation is published.

Association between genetic polymorphisms in DEFB1 and microRNA202 with caries in two groups of Brazilian children.

OBJECTIVE: This replication study aimed to evaluate an association between caries experience and polymorphisms in DEFB1 and miRNA202 in two different Brazilian groups. DESIGN: The population consisted in 312 Brazilian children. Genomic DNA for was extracted from buccal cells isolated from saliva. The genotyping analysis of the polymorphisms in DEFB1 and miRNA202 was performed by real-time polymerase chain reactions. The associations between caries experience, genotype and allele distribution was performed, with an alpha of 0.05. RESULTS: A statistical significant difference was observed between allele distribution and the polymorphism rs12355840 in the miRNA202 for permanent dentition in the Manaus group, in which individuals that carry the allele C had almost three times more chance to have caries (p = .021; OR = 2.7, 95% CI = 1.1-6.7). In the Ribeirão Preto group there was a statistical significant difference for the polymorphism rs11362 in the DEFB1 for both dentition in alleles (p = .043) and genotype (p = .020) distributions. The T allele increased in two times the chance to have caries (OR = 2.03; 95% CI = 1.05-4.07). CONCLUSION: In conclusion, the allelic distribution of the polymorphism rs12355840 in miRNA202 was associated with caries experience in the Manaus group. In the Ribeirão Preto group, the allelic and genotypic distributions in the polymorphism rs11362 in DEFB1 were associated with caries experience.

Abstract The objective of this study was to compare selective physical-mechanical properties, antibacterial effects and cytotoxicity of seven temporary restorative materials (TRM): five resin-based materials [Bioplic (B), Fill Magic Tempo (FM), Fermit inlay (F), Luxatemp LC (L) and Revotek LC (R)], and zinc oxide-eugenol cement (IRM) and glass ionomer cement (GIC) as the controls. Material and methods The physical-mechanical properties were evaluated by determining microleakage (ML), ultimate tensile strength (UTS) and Shore D hardness (SDH). In addition, the polymerization rate (Pr-1), depth of cure (DC), water sorption and solubility (WS/SL) were evaluated. The antimicrobial effects of the materials were assessed by biofilm accumulation of Streptococcus mutans (BT) and the direct contact test (DCT) by exposure to Enterococcus faecalis for 1 and 24 h, and cytotoxicity by MTT assay. The data were analyzed by ANOVA or Kruskall-Wallis tests, and a complementary post-hoc method (p<0.05). Results Group B, followed by FM and GIC had significantly lower percentages of microleakage in comparison with the other groups; Groups FM and L showed the highest WS, while Groups R and FM showed the significantly lowest SL values (p<0.05). Group R showed the statistically highest UTS mean and the lowest DC mean among all groups. Group F showed the lowest S. mutans biofilm accumulation (p=0.023). Only the Group L showed continued effect against E. faecalis after 1 h and 24 h in DCT. The L showed statistically lower viability cell when compared to the other groups. Conclusions These findings suggest the antibacterial effect of the temporary materials Fill Magic and Bioplic against S. mutans, while Luxatemp showed in vitro inhibition of S. mutans biofilm accumulation and E. faecalis growth. Regarding the cell viability test, Luxatemp was the most cytotoxic and Fill Magic was shown to be the least cytotoxic.

A cadeia produtiva de carne bovina no Brasil destinada à exportação / The productive cattle of beef in Brazil destined for export

A carne bovina é um importante segmento do agronegócio brasileiro, com significativa participação no valor das exportações do País. Visando manter-se competitivo frente às exigências do mercado externo, principalmente europeu, o Brasil implementou o Sistema de Identificação e Certificação de Bovinos e Bubalinos (SISBOV). Este sistema tem como objetivo monitorar toda cadeia produtiva brasileira, certificando que o Brasil exporta um produto livre de contaminação. Este trabalho teve como objetivo analisar as adequações que o Brasil realizou no seu sistema agroindustrial com a finalidade de atender ao mercado internacional. Utilizou-se uma metodologia exploratória, por meio de revisão bibliográfica no período de 2007 a 2015. A implantação de um sistema de rastreabilidade na indústria provocou uma série de modificações em toda a cadeia produtiva brasileira, porém, o alto custo deste sistema para o pecuarista, conjugado a pontos falhos na legislação brasileira, vem limitando o desempenho brasileiro. A necessidade de mais investimentos na cadeia produtiva torna-se inquestionável.
