Published: May 2019

In recent decades, in addition to the traditional grain storage in dry conditions, the technology of grain storage without access of air - in hermetic conditions has gained a widespread in polymeric grain bags (silobags). The aim of the research was to study the regularities of the physiological processes of respiration in maize grain when stored in hermetic conditions, which would determine the terms of safe storage of different humidity grain in polymeric grain bags and reduce the costs of its processing and storage. The object of research is the technology and processes of freshly harvested corn grainstorage. As the main subject of the study, a dent-type hybrid of corn DKS 3705 was used, which, according to its botanical and agronomic properties, was better for use on food and non-food needs and for export. On the basis of the conducted researches it was established that with an increase in initial moisture of grain from 14% to21% and subsequent storage in hermetic conditions at constant temperatures the natural losses of dry matter of grain increase in comparison with losses of dry matter of grain with standardhumidity (14%), in particular, at a temperature of 18 ºС by 112%, at a temperature of 11 ºС by 296% and at a temperature of 4 ºС by 123%. Thus, it is shown that the decrease of the temperature regimes of grain storage of maize with different initial humidity under hermetic conditions contributes to the reduction of the intensity of thenatural physiological processes in it and, consequently, the natural losses of its dry matter. It has been established that during storage of corn grain for three months and reduction of temperature storage conditions from 18 ºС to 11 ºС in samples of grain with an initial humidity of 14% decrease: the absorption rate of oxygen by 34%, carbondioxide emissions, loss of dry matter and the production of thermal energy by 66%. For a grain with an initial humidity of 21%, the reduction in intensity under the same conditions is: for absorption of oxygen 22%, the production of carbon dioxide 28%, losses of dry matter 37% and the production of thermal energy 23%. Reducing the storage temperatures of corn from 11 ° C to 4 ° C in samples of grain with an initial humidity of 14% reduces the intensity: absorption of oxygen by 79%, carbon dioxide generation by 60%, dry matter loss by 60%, and the generation ofthermal energy by 60%. For grain with an initial moisture content of 21% under the same conditions, the intensity decreases: oxygen absorption by 28%, carbon dioxide generation by 77%, dry matter loss by 77%, and heat generation by 77%. Established regularities of the physiological processes in corn grain with different initial humidity when stored in hermetic conditions at different temperatures, it is possible to predict the characteristics of gas exchange processes in the grain mass, natural losses of dry matter and the generation of heat during storage of grain.

This paper presents the features of corn as raw material for groat industry. Corn is used in many segments of the food andprocessing industry. corn is processed for traditional food products — groats, flakes, flour, extruded foods, and other corn byproductsare widely used for the production of dry breakfast cereals, snacks, cereal bars. In terms of using of the advanced processingtechnologies, the industry produces starch, gluten, and germs. Corn germ is used to produce the high-value vegetable oil, aswell as starch — for both food and non-food purposes. More than half (65%) of corn is used for feed purposes, 25% –technical purposes,and nearly 20% – for various types of food production. corn is processed for traditional food products — groats, flakes, flour,extruded foods, and other corn by-products are widely used for the production of dry breakfast cereals, snacks, cereal bars. For thecolour, corn is divided into white and yellow types. According to the literature data analysis, yellow corn is more used in China,Argentina, Brazil, while white corn — in some countries of Asia, Latin America, and the Balkan countries. Depending on itsmorphological features, the corn kernelis divided into various groups, species and subspecies.In Ukraine corn kernel is classified into 8 types, with separately defined limitations on the content of the major crop in thebatch, grains of other type, etc. Corn of І-VІІІ types with the quality indicators specified in the standard, for the production of foodproducts. Flint and dent corn types are the most applied grain varieties in the industry, they are widely used in the production segmentof food and feed products. Sweet corn is widely used as a vegetable crop in the food canning, food concentrates, starch andbrewing industries due to its flavor properties. Popped corn is not only the most convenient raw material for the production of popcorn,but it also can be used as the raw material for the production of corn curls and dry breakfast cereals By analyzing the weightfraction of fat in kernels of different corn varieties we can note that the lowest number of fat is typical for popped corn (4.0%) andthe largest – for sweet corn (9.1%); dent and flint corn have the same total fat number (4.5-4.9%).Test weight of corn types – poppedcorn ranges within 712-826 g/l, dent corn - 875-893 g/l, and flint corn - 768-786 g/l.

Published: May 2019

Aim of the study is to describe the phenomenon of post-religion as a specific spiritual sphere of the Post-modernity. Methodology. In the introduction analyzed a variety of methodological approaches, opening his inadequacy applied to the spiritual sphere of Post-modernity: «classic» religious studies, religious studies of traditional spiritual movements and the post-modern religious studies, partly produced Traditionalist school, could - according to the author's hypothesis - become a methodological basis for the most complete analysis of post-religion. Scientific novelty. In the main part of the article crystallized the authorized concept of post-religion, its relation with traditional and religious spiritual realms. Post-religion is positioned as the top of secularism enshrined in the departure from the straight and aggressive secularism of the Modernity, but without recourse to Tradition. Post-religion a simulation spirituality, skillfully imitating the outer areas of traditional spirituality and creates a planar religiosity, radically preventing attached to the vertical line of Traditions. In this regard, are the main artificially selected parameters of post-religion: deconstruction, splitting, virtualization, and collage. Deconstruction is a transformation of spirituality in semiotic set for egocentric selectivity of modern believer. Post-religion’s splitting is deprivation of spirituality center, destruction of sacral Center and the transformation of spirituality in the plane on which the intellectual and sensual wandering post-believer from one semiotic island to another. Virtualization is a displacement field of spiritual tension in a completely virtual area, isolated from the natural conditions of existence and created as his replacement, network discussion sites and galleries. Collage is an arbitrary combination of different semiotic pieces of Tradition with the aim of creating a believable picture of tradition; it is collage leads to archaic forms of modern spirituality. Findings. Thus, based on the above study phenomenological illustrations, can declare one can argue that Post-modernity is much wider than the decadent direction of the culture is a radical shift of spirituality, the top of desacralization.
VOLTAIRE’S PHILOSOPHY: HUMAN NATURE AND INTERPRETATION OF RELIGION
Authors: Yu. Zimaryova
Published: May 2019

The purpose of the article is to determine and reconsider Voltaire’s ideas concerning religion and human nature. In order to achieve this purpose it is necessary to complete the following tasks: to analyse academic literature on Voltaire’s interpretation of the phenomenon of religion; to expose Voltaire’s basic ideas about human nature; to substantiate the importance of anthropological approach to the phenomenon of religion with the ideas of Voltaire’s philosophical works. Methodology. The achievements of anthropocentric philosophical thought of the XIX century possess great potential in the process of constructive comprehension and theoretical reconstruction of the anthropological intention that accompanies the process of philosophising. The research extensively applies hermeneutical method for interpreting Voltaire’s philosophy. Scientific novelty. In academic literature on Voltaire’s works we have ascertained the basic anthropological component of his philosophy and reconsider Voltaire’s ideas about religion as something that is rooted in human nature. Conclusions. In academic literature the interpretation of the phenomenon of religion in Voltaire’s heritage is a rather controversial one. At the one hand, Voltaire criticizes religion for its superstitions and fanaticism. On the other hand, he recognises the existence of God. In our opinion, the phenomenon of religion should be examined in the context of human nature and basic problems related to it such as the problem of soul and the problem of free will. The anthropological approach to the phenomenon of religion allows to avoid the extremity of atheistic and metaphysical approaches and to enable its anthropological interpretation.

Published: May 2019

Purpose. The main purpose of the work is to carry out a kinematic synthesis of a crank-slider gripping device in accordance to the criterion of the constancy of the drive power of the mechanism with restrictions on permissible pressure angles in kinematic pairs. Methodology. Achieving this purpose is carried out by means of the theory of mechanisms and machines using the analytical method of the Ozols triangles of kinematics of plane rod mechanisms and mathematical modeling of the movement of links. Findings. The ten-bar mechanism of the gripping device is built on the basis of a paired parallelogram of a crank-slider mechanism with a leading slider. For gripping device, which is built on the basis of the rod scheme, it is advisable optimal design using the criteria for the transfer of motion or transmission indices. The criterion of optimization is the ratio of the speed of the leading link to the projection of the velocity vector of the driven point on the direction of the clamping force vector (power transmission index). The lowest energy costs can be achieved, provided that this ratio is equal to one. Analytical dependences are obtained for determining the velocity function of the central and de-axial crank-slider gripping device, which are convenient for analysis and modeling. On their basis, an energy synthesis of the geometrical parameters of the mechanism of the gripping device in accordance with the criterion of the smallest deviation from the unit ofpower transmission index is performed. The possibilities of the gripping device are enhanced by using it in a de-axial crank-slider mechanism, and the best results can be obtained in a scheme where the de-axial value is larger than the crank length. It is determined the specific values of the relative parameters of the lengths of the links and the ranges of rotation of the crank of the central and de-axial crank-slider of the grippingdevice, which best meet the optimization criterion and satisfy the pressure angle constraints. Originality. For the first time, a new criterion for the transmission of motion was introduced –power transmission index. According to this criteria, a kinematic synthesis of the gripping device built on the basis of a paired crank slider mechanism was carried out. Practical value. Practical recommendations are proposed on the size and location of the links of the mechanism for the central and de-axial crank-slider mechanism, which satisfy the requirements of the optimization criterion and implement restrictions on permissible pressure angles.

Published: May 2019

Purpose. The work is aimed to clarify the softening mechanism during the heating of martensite hardened carbon steel, which is of practical importance, especially in the development of the production technology of rolled products with different levels of hardening. Methodology. The samples after martensite hardening were tempered at the temperatures of 300-500˚С. The microstructure was investigated under the electron microscope. Thin foils were made using the Bolman and tweezer methods in chlorous-acetic solution and Morris reagent. Phase distortions of crystalline lattice were determined by the methods of X-ray structural analysis, using the diffractometer. The cold-worked layer of metal after grinding was removed by electrolytic dissolution. Tensile strength brake of the metal was determined using the tensile diagrams of samples using the Instron type machine. Microhardness was measured using the PMT-3 device with indentation load 0.49 N. Findings. When heating the hardened steel to a temperature of 300˚C, the softening effect is mainly related to the rate of reduction of the accumulated as a result of martensitic transformation, density of the crystalline structure defects. The total result is caused by the development of dislocations recombination and strengthening because of the emergence of additional number of cementite particles during the martensitic crystals decomposition. Starting from the heating temperatures of 400˚C and above, the development of polygonization processes in the ferrite is accompanied by the emergence of additional sub-boundaries, which enhance the effect of metal strengthening. With increase in the heating temperature of the hardened steel, the level of strength properties is determined by the progressive softening from the decrease in carbon atoms saturation degree of the solid solution, dislocations density and increase in the size of cementite particles over the effect of strengthening from hindering of mobile dislocations by carbon atoms and the emergence of additional sub-boundaries. Originality. For the tempering temperature of 300-400˚C, the absence of the phase distortion change indicates the emergence of additional factor in strengthening the metal from the formation of sub-boundaries and the dispersion strengthening from the carbide particles. Practical value. The given explanation of the mechanism of structural transformations in the process of tempering in the average temperature range of the hardened carbon steel can be used to optimize the technology of thermal strengthening of rolled metal.

Authors: A. O. Lovska
Published: May 2019

Purpose. The research is aimed at revealing the peculiarities of stability determination for a tank container relative to the frame of a flat car during transportation by train ferry. Methodology. In order to reach the purpose, the mathematical modelling of dynamic loading of a tank container located on a flat car during the train ferry transportation was conducted. The model takes into account the tank container displacements relative to the flat car frame and liquid cargo in the tank, the displacements of which are limited by the tank’s walls. It was assumed that the flat car, with tank container on it, was rigidly fixed relative to the deck of the train ferry and moved together with it. A 1CC type tank container located on a 13-4012 flat car was chosen as a prototype. While designing the model, the following aspects were considered: the trochoidal law of motion of the disturbing action (sea waves) on the train ferry with containers, the dissipative component occurring due to the train ferry oscillations under conditions of sea rolling, the relative bearings of sea waves to the train ferry body, and the wind force to the above-water projection of the train ferry, flat car located on the upper deck and tank containers. The differential equations of motion were solved in the Mathсad with their reduction to the normal Cauchy form with subsequent integration by the Runge–Kutta method. The acceleration values obtained, as the components of the dynamic loading, were considered in the stability research for the tank container relative to the flat car frame. Findings.  The author obtained the clarified values of dynamic loadings, acting on the tank container located on a flat car during the train ferry transportation. Originality. A mathematic model of displacements of a tank container located on a flat car during the train ferry transportation was developed. Practical value. The findings of the research can be used at designing tank containers of a new generation with improved technical and economical, as well as ecological indices.

Purpose. The article is aimed to ensure the operation safety, increase in the strength and durability of the most loaded supporting elements of rolling stock – bogies, in particular the bogies of the DPKr-2 diesel train. Methodology. In order to assess the design strength of the bogie prototype, a spatial solid-state 3D model was constructed. Using the software package implementing the finite element method, the most loaded nodes of the bogie frame are determined based on the Palmgren–Miner–Mises theory. During the finite element modeling, the peculiarities of the design work in operation, the action of static loads and the corresponding dynamic additives are taken into account. The results of calculation were used to develop the layout diagram of the strain gauges on the bogie frame during the running strength tests. According to their results, the fatigue strength of the bogie frame prototype under the action of operating loads was estimated and a conclusion was made about the need to strengthen its design. The design management of the PJSC «Kryukov Railway Car Building Works» proposed the variant of enhancing the bogie frame prototype. Findings. Based on the results of theoretical and experimental studies, the prototype design of the DPKr-2 diesel train was modernized, which made it possible to reduce stresses in the most loaded nodes and significantly increase its durability. Strength calculations and running strength tests of diesel trains with modernized bogies were carried out. Originality. For the first time, a spatial finite element model of the new generation diesel train was constructed and the strength calculation was carried out under the action of design loads. The constructed model made it possible to choose the variant of modernizing the frame prototype that satisfies the fatigue strength conditions. The conducted experimental studies have shown the efficiency of modernization, in particular the increase in strength and durability of the design. Practical value. The complex of design and experimental work on the assessment of the stress-strain state of the bogie frame of the DPKr-2 diesel train under the action of design and operating loads allowed creating a design that satisfies both the operational requirements and the requirements of strength and durability. The developed design of the bogie frame makes it possible to increase the operation safety and can be used in the next generation diesel trains.

The Epidemiological investigation of the diseases affecting the maxillofacial structures is of fundamental importance to the dental clinic. However, few studies on this subject have been published in the literature, despite its relevance to the viability of health programs. In this context, the objective of this work was to assess the frequency and the main types of diseases that are commonly biopsied and sent to the Pathology Department, School of Dentistry from EBMSP. By conducting a retrospective study covering the data collected during the years 2001 to 2010, 1.095 biopsies were evaluated. Considering the histopathological diagnosis of each case, it was also evaluated the frequency of pathological lesions, the overall distribution of the samples by sex and age, lesion location, and clinical and histopathological diagnosis. The most frequent diagnoses were fibroepithelial hyperplasia (16.62%), nonspecific chronic inflammation (6.30%) and radicular cyst / residual (4.87%). The importance of searching for the correct diagnosis of the pathology presented by the patient is so relevant as the choice of methods and techniques to be used in their elimination or control. It is clear that a better and more accurate diagnosis contributes to a well developed treatment.

Introduction - Forensic Dentistry has great importance in the identification process, especially when professionals receive only the cephalic  portion of the body for analysis. The purpose of this study is to assess sexual dimorphism and age estimation using the  Transverse Cranial Index. Materials and methods - We studied a sample of 160 dry skulls, 80 males and 80 females, who belonged to individuals over the age of 20 years, and with age and sex known with absolute certainty. The studied skulls belonged to people whose relatives had not claimed their remains in the time established by the Cemetery administration and they were being sent for cremation. The following measurements were carried out:  the distance between the basion and bregma (maximum cranial height) and the distance between the eurio and eurio (maximum cranial width) and from these we calculated the Transverse Index. Results - According to statistical analysis, there was a success rate of 81.5% by logistic regression and 76.25% with discriminant analysis. The results were verified and the confidence interval was average throughout the test. The method of multiple linear regression used to predict the age was used, noting that the model was not significant (p = 0.3223). Conclusions - The results allowed the development of statistical methodology for the diagnosis of sex and age on future observations.

Nonsyndromic cleft lip and/or palate (NSCL/P) are the most common congenital anomalies of the face. Dental abnormalities located inside and outside the cleft region are the most frequent dental characteristics found in these individuals. The aim of this paper is to review the literature on dental abnormalities associated with NSCL/P. A search for articles was conducted on electronic databases such as Medline, Lilacs and PubMed. According to the literature, dental abnormalities were more common in permanent dentition. Agenesis and supernumerary teeth showed the highest prevalence. The upper lateral incisor was the most affected teeth by agenesis, supernumerary teeth and microdontia. The teeth located closest to the cleft were more susceptible to defects. The presence of dental anomalies outside the cleft region suggests the presence of genetic events involved in both odontogenesis and craniofacial formation.

Periodontal disease is multifactorial and it affects the tissues surrounding the teeth. Its etiology includes microrganisms as Porphyromonas gingivalis, Tannerella forsythia and Aggregatibacter actinomycetemcomitans. This work aimed to discuss the role of Porphyromonas gingivalis in chronic periodontitis. The electronic bases PubMed, BIREME and SciELO were used to search for historical aspects and studies published between 2000 and 2015, using the following descriptors in Portuguese and English: “Chronic periodontitis, Porphyromonas gingivalis” and “Virulence factors”. 205 articles were found and 24 were included. Records on periodontal diseases from the early civilization to the present day were found. Its prevalence in the world’s population remains high and several studies report the pathogenesis of the disease. P. gingivalis is able to induce humoral and cellular response in infected individuals. Studies on its escape mechanisms and virulence factors report tissue breakdown consequent to immuno-inflammatory exacerbated response in the host which may evolve into edentulism. Studies of the immune response to P. gingivalis suggest its role in perpetuation of the inflammatory state by interfering with cytokines production and cell death mechanisms in the host’s cells, resulting in tissue destruction. The current knowledge about mechanisms of infection and virulence factors of P. gingivalis indicate its role as a key component in chronic periodontitis.

Introduction: In the practice of dentistry, the dentist may be held responsible for their actions or omissions that result in damage to their patients. Such responsibility may occur in the ethical, civil and criminal spheres, among others. Over the years, the society and the professional-patient relationship have changed supported by current legislations, as well as increased information and communication. So, we have witnessed an increasing number of disputes in court involving dentists and theirs patients, which reveals the importance of professionals to know the regulations in the practice of dentistry and the consequences of the illegal act. Objective: The present study aimed to provide knowledge, through a literature review, on the legal aspect of professional responsibility of the dental surgeon and to highlight the importance of dental documentation as a means of proving professional performance. Methods: It was used books, theses and scientific papers published in electronic databases such as SciELO, Bireme, MedLine and Lilacs, in Portuguese language, besides laws and regulations published in official electronic addresses. Conclusions: It was concluded that an adequate medical record protects the professional; as documentation fails, compromises all work done and may result in condemnation.

Objective: This study aimed to review the literature on the quality of life related to swallowing of patients with head and neck cancer. Methods: We searched for studies describing the physiology of swallowing and aspects involved in dysphagia, such as definition, causes and their impact on quality of life. We used the electronic databases Pubmed, Medline, Scielo, books, as well as articles identified in the references. Results: Deglutition disorders may occur due to disease and / or treatment modality, persisting during or after termination of treatment. The frequency and severity of dysphagia will depend on the modality of treatment used, location and stage of the tumor, when involved in structures that participate in swallowing. Patients with tumors in more advanced stages and located in the pharynx try to present worsening of swallowing function. Such factors may directly affect swallowing and quality of life of the patient, especially in family, social and lifestyle relationships. Conclusion: Although it does not replace clinical and instrumental evaluations, investigating the quality of life in swallowing may contribute to assess specific aspects of patient well-being that are not contemplated.

Objetivo: analisar o grau de satisfação profissional de auxiliares de saúde bucal (ASBs) dos setores privado e público de um município no sudoeste da Bahia. Material e Métodos: amostra constituiu-se de 43 indivíduos, sendo 16 do setor público e 28 do privado. Utilizou-se questionário que analisa cinco fatores relacionados a dimensões específicas de satisfação do indivíduo com o seu trabalho: relacionamento interpessoal, remunerações, chefia, natureza da tarefa e promoções. Os dados foram analisados no pacote estatístico SPSS. Resultados: predominou-se o sexo feminino (100%), com faixa etária entre 26 a 35 anos (32,6%), grau de escolaridade ensino médio completo (67,4%), com 5 a 10 anos de tempo de trabalho (32,6%) e sem registro no Conselho Regional de Odontologia (CRO) (76,7%). Houve maior satisfação para as dimensões relacionamento interpessoal e chefia e menor para remunerações. As ASBs com idade entre 18 e 25 anos estavam mais satisfeitas que as demais com maior idade em relação à dimensão chefia (p<0,05). Para a dimensão promoções, as profissionais sem registro no CRO indicaram maior satisfação que aquelas com registro (p<0,05). Conclusão: As ASBs do setor privado mostram-se mais satisfeitas do que as da rede pública, e houve maior grau de insatisfação para remunerações.

Objetivo: avaliar a cor de três resinas compostas de cor A2 e A3 de diferentes marcas comerciais, através da análise por espectrofotômetro VITA Easyshade® Compact. Método: Para a análise de cor, foram confeccionados 36 corpos de prova (n=6), em formato de disco, a partir de uma matriz de aço. Para cada espécime, foi realizado 5 aferições e os valores de L*, a*, b* e L*, C*, h* anotados. Resultados: Verificou-se que a cor A2 diferiu estatisticamente da fornecida pela escala vita (p<0,0001), e diferenças estatísticas entre as resinas compostas não foram observadas (p=0,56). As resinas compostas Opallis e Fill Magic de cor A3 diferiram estatisticamente da fornecida pela escala vita (p<0,0001), porém o mesmo não foi observado com a resina composta Filtek Z250 e diferenças entre as resinas compostas foram observadas (p=0,56), sendo a resina composta Opallis e Fill Magic semelhantes entre si e estatisticamente diferentes da Filtek Z250. Conclusão: Conclui-se que a maioria das resinas compostas estudadas não  apresentou correspondência de cor positiva com a escala de referência VITA Easyshade® Compact, o que dificulta a execução do profissional durante procedimentos restauradores estéticos.

Neste trabalho, cujo tema é avaliação da diferença de retenção e estabilidade da prótese total usando materiais anelásticos e elásticos na moldagem funcional: um relato de caso, foi estudado os materiais elásticos e anelásticos utilizados na moldagem funcional de uma prótese total, avaliando os pré-requisitos retenção e estabilidade, buscando reconhecer o material que apresenta maior vantagem para uso cotidiano na clínica, onde o mesmo apresente uma boa manipulação, garanta um conforto ao paciente e apresente um resultado funcional satisfatório. Decidiu-se realizar este estudo em meio as dificuldades clínicas encontradas e também relatos sobre a dificuldade em escolher um material, em meio a tantos, para realizar a moldagem funcional, que é uma etapa essencial na confecção de uma prótese. Sabendo da variedade de materiais existentes, buscou-se um conhecimimento prático que indicasse um  material que possa ser escolhido para essa moldagem com mais segurança, que apresente ao final uma prótese com boa retenção e estabilidade. Realizou-se coleta no prontuário de uma paciente onde haviam sido confeccionadas duas próteses totais, onde uma foi utilizado na moldagem funcional um material elástico e na outra um material anelástico. É possível perceber na prática clínica que um grande número de profissionais utilizam mais os materiais elásticos na moldagem pelas vantagens apresentadas, vantagens essas que foram possível vivenciar neste estudo, como uma melhor manipulação, manuseio, limpeza dos resíduos e o resultado final.

A avulsão é uma sequela de traumatismo grave, caracterizada pela total desarticulação do dente com seu alvéolo. O tratamento após a avulsão de um dente permanente deve ser o reimplante imediato, caso não seja possível, deve ser mantido em um meio que permita a viabilidade das células do ligamento periodontal. Este trabalho foi realizado com o objetivo de avaliar o conhecimento dos dentistas clínicos e acadêmicos do último ano de Odontologia sobre os meios de armazenamento e reimplante dentário. O estudo é descritivo, com amostra de conveniência de clínicos e formandos (n=100), que responderam questionários sobre a avulsão dentária e o meio utilizado para transportar tais dentes. Com relação à realização do reimplante, 94% responderam que fariam e 6% não teriam capacidade de fazer. Dentre os que fariam, 91 % lavariam antes de reposicionar o dente no alvéolo, sendo que 53% com soro fisiológico, 42% com água corrente, 3% com leite e 2% com água destilada. A maioria encaminharia para um endodontista (72%), entretanto, 19% não encaminharia para um especialista. Quanto ao meio de armazenamento antes do reimplante, 57% julgaram ser na própria boca, 19% num frasco com leite, 18% num frasco com soro e 6% num frasco com saliva. Sobre o período ideal para o reimplante, 83% julgaram ser imediatamente após a avulsão, 15% entre 30 minutos e 1 hora e 2% entre 1 a 4 horas. O conhecimento sobre o manejo dos dentes avulsionados na comunidade odontológica é satisfatório, entretanto, ainda se percebe alguns equívocos com relação ao tema.
