Osmotic Oedometer Using Sodium Chloride Solution and Reverse Osmosis Membrane
Authors: Bulolo Sam , Leong Eng-Choon
Published: August 2020

There are two suction application techniques in laboratory testing of unsaturated soils: (1) the axis-translation technique in which pore-air pressure is elevated above atmospheric pressure and pore-water pressure is at an atmospheric or a small positive value to give a matric suction and (2) using salt solutions. Salt solutions can be used to control the relative humidity of the air surrounding the soil specimen in the vapor equilibrium technique or as an osmotic suction applied through a semipermeable membrane in the osmotic technique. The salt solution in the vapor equilibrium technique applies a total suction, whereas the salt solution in the osmotic technique induces a matric suction on the soil specimen. Unlike the axis-translation technique and vapor equilibrium technique, the osmotic technique does not require a sealed chamber, but it is not as popular as the axis-translation technique and vapor equilibrium technique because the commonly used poly(ethylene glycol) solution and cellulosic membrane are susceptible to degradation during long-duration tests. This paper investigates the osmotic technique using sodium chloride solutions and a reverse osmosis membrane in a conventional oedometer. The performance of the updated osmotic oedometer was evaluated using kaolin–bentonite specimens. A kaolin–bentonite specimen was first mechanically consolidated, and thereafter the water within the base of the oedometer was replaced with sodium chloride solution. The results show that osmotic technique causes the soil specimen to be compressed further. However, the measured matric suction of the soil specimen at equilibrium is less than the applied suction. The difference is attributed to the membrane resistance effect. The updated osmotic oedometer is attractive, as it eliminates the drawbacks of the previous osmotic oedometer, and it can theoretically apply matric suction as high as 5,000 kPa.

As real-world systems become more complex and connected, the industrial sector requires engineers who can solve problems across multiple disciplines and work with people across various educational backgrounds. This is particularly apparent in the manufacturing industry, as the integration of new manufacturing system technology requires knowledge in a diverse set of fields, such as physics, computer science, and engineering, to name a few. To properly educate the next workforce in manufacturing, engineering education needs to incorporate cross-disciplinary, project-driven learning that provides students with ample opportunities to work with cutting-edge manufacturing technology. At the University of Michigan, the Secure Cloud Manufacturing Multidisciplinary Design Program team focuses on developing the next generation of manufacturing engineers through research-driven multidisciplinary projects. A group of 7–22 students work on several multisemester-long projects that focus on providing hands-on, student-driven learning. Each semester, these students work closely with several faculty members, research scientists, postdocs, and graduate students to propose, develop, and conduct industry-relevant research projects on multiple manufacturing testbeds. Example projects have included the implementation of a smart quality-control camera, the development of digital twins for manufacturing processes, and the integration of secure cloud-based infrastructures for industrial controllers. In these highly collaborative and multidisciplinary project groups, students learn from each other, take on leadership roles, and disseminate their work through technical reports and presentations to academic and industry experts. Students leave the group with an understanding of the capabilities and needs of future manufacturing systems, ready to become, and lead, the next set of manufacturing engineers.

Covid-19 is a contagious pulmonary infectious disease caused by a new type of coronavirus (SARS-COV-2). Covid-19 is a global pandemic that has infected millions of people and killed thousands of people in the world. Cases of death in Covid-19 patients were first discovered in China in December 2019. In Indonesia, since it was first discovered, cases of death of Covid-19 patients continue to increase and has become one of the countries with the highest fatality rate in the world reaching 9.11 percent. The purpose of this study is to determine risk factors for death in covid-19 patients in China in order to get guidance in preventing death in Covid-19 patients in Indonesia. This type of research is a literature review. The results of the study found five risk factors for death in Covid-19 patients, namely age, Covid-19 complications, the immune system (immunity), concomitant diseases (cormobidity), and treatment facilities. Suggestions of various risk factors for death in Covid-19 patients in China are expected to be a guide in efforts to prevent death in Covid-19 patients that occur in Indonesia.
An An Approach to Measure the Death Impact of Covid-19 in Jakarta using Autoregressive Integrated Moving Average (ARIMA)
Authors: Fadly Ferdian , Sari Erika
Published: August 2020

Coronavirus disease 2019 (COVID-19) is a pandemic in more than 200 countries around the world. As the fourth most populous nation in the world, Indonesia is predicted to face a big threat to this pandemic particularly Jakarta as the epicenter of the virus in Indonesia. However, the nature of COVID-19 that can easily spread and also many undetected cases that do not present symptoms make it more difficult to determine the real mortality effects of COVID-19.The deaths in Jakarta from the new coronavirus may be higher than officially reported. To overcome this issue, this paper will provide an approach to measure the death impact of COVID-19 using the Autoregressive Integrated Moving Average model (ARIMA). The model will predict the ‘what if’ normal condition of the number of funerals in Jakarta compared to the real situation in March 2020 as an approach of the actual effect of COVID-19 in Jakarta. This research revealed a discrepancy of 450-1070 funerals in March 2020 that could not be predicted by the ARIMA model. This funeral gap, a forecast error, could be an approach to the potential number of possible death impacts of COVID-19 in Jakarta that should be significantly higher than the report. The people should be more conscious and alert of COVID-19 situation.
La metodología de control emocional en conversaciones con padres, madres y personas apoderadas y eldesarrollo de habilidades conversacionales en docentes. Evidencia desde Chile
Authors: Quiroga-Lobos Marta , Aravena-Castillo Felipe
Published: August 2020

The present study explains and evaluates the ECSC methodology (Emotional Control in Conversations with Parents) through its implementation in a primary school in Chile. The methodology’s goal is to develop skills in the teachers’ heads to conduct interviews with parents classified as difficult, and parents of students with low academic results and/or disruptive behavior in the classroom. Parallel to training, the D. L. Kirkpatrick and J. D. Kirkpatrick (2006) evaluation model was applied in its four steps: satisfaction, acquisition of theoretical knowledge, the sustainability of practices, and organizational effects. It was concluded that the methodology could develop skills for teachers to recognize emotions, select types of conversations, analyze evidence of learning with parents and plan, together, short-term goals associated with learning. The results also enrich the methodological proposal in three aspects: first, to make the intensive feedback cycles initially and to gradually differ according to the needs of the participants; second, to include specific actions in the methodology, for the management team, on time management, infrastructure management, and the animation of collaborative work among peers; third, this methodology can be transferred to other formative contexts, since it satisfies real needs in the school system.

Authors: Ramos-Monobe Arcelia , Gallardo-Córdova Katherina , Camacho-Gutiérrez Dulce
Published: August 2020

This article is the result of four case studies in Mexico and Colombia with students from the Learning Evaluation course (Gallardo Córdova, 2017) of an online postgraduate program in education. The study aimed to analyze the participants’ decisions based on the results of a diagnostic questionnaire on learning assessment practices. The students’ decisions relate to the preparation of materials or the change in practices to influence the conduct of the summative and formative evaluation. Eighteen teachers and management staff members participated in the four cases analyzed. The main results were to understand that, in most cases, decision making was more inclined to consolidate the theoretical aspects that sustain the practices, such as the definition of types of evaluation, integration of learning taxonomies, instrumentation, and feedback. Likewise, in terms of international standards stated by the Joint Committee on Standards for Educational Evaluation (JCSEE), especially those related to the Utility, Feasibility and Ethics were integrated into the decision making to educate and sensitize teachers. The complexity and the demand for the time required by the evaluation processes were confirmed, specifically those of a formative nature. It is concluded that the process carried out allows the participants to reflect on the evaluation practices for a continuous improvement.

Authors: Novoa-Palacios Amparo
Published: August 2020

The article analyzes the experience of eleven coordinators from the Superior Normal Schools of Colombia (ENS). They enrolled in the Educational Social Innovation Program. The goal is to study their perception of educational leadership based on values and innovation. The methodology used is the systematization of experiences, with a qualitative approach that articulates descriptive research and the method of research and documentary analysis. The results were obtained through the conceptual, comparative, and relational analysis of eleven leaders-coordinators’ contributions from the Superior Normal Schools. In these institutions, the analysis identified some aspects characterizing the innovative educational integral leader as someone who contributes to solving socio-educational problems. These can be solved from responses located in the territory and from a sense of belonging that integrates the different spheres of life experience. This means prioritizing dialogue and solidarity and assuming tension and conflict as part of ongoing learning from an axiological framework. Likewise, the analysis found that the territory, the educational projects, and the strengthening of community-based competencies constitute aspects that make an integral, innovative, educational leader someone capable of combining community methodologies based on in-depth knowledge of the communities’ problems.

Published: August 2020

This article takes as reference the problems that exist due to the lack of reading, mathematics and science skills, according to the reality of the Mexican public education system, as well as the results obtained in the evaluations promoted by the Organisation for Economic Cooperation and Development (OECD). The research was based on a quantitative study, which was conducted from a diagnostic evaluation on the development of information and thinking skills in children in basic education school. This research designed and applied three instruments on thinking skills, mathematical thinking, and information, language and communication skills in children. The research aimed to know the level of skills developed prior to joining the program of the new educational model proposed by the Ministry of Public Education (SEP) of Mexico when applying the method of the diagnosis of educational situation (DS) that has the following components: i) an examination of 20 exercises to measure the level of development of each skill under study; ii) a rubric to evaluate the children’s responses; and iii) a table to record the results of each skill. The diagnostic evaluation concluded that students, who are in the preoperative stage, have some development in their thinking skills (observation, comparison, classification, ordering, inferences, memory and storytelling), linguistic skills (they write their name, without surnames, communicate emotions, tell short stories, oral language stands out), and informative skills (there are no notions of concepts that intervene).

Published: August 2020

Teaching communicative competences to future teachers has become a need for the European Higher Education Area (EHEA). In this regard, it is essential to know the writing competence of the teachers in training and, specifically, their skills when it comes to writing a text. For that reason, this research article aimed to validate an analytical rubric to evaluate expository texts written by university students. The tool has taken into consideration seven general dimensions assessed according to an estimation scale, ranging from excellent to deficient, including good and acceptable. The validation of the tool was carried out using a mixed methodology (quantitative-qualitative), in which initially 12 independent judges validated its content, and then a statistical validation with the statistical package software (SPSS) was conducted. The results were the obtention of the unanimity of judgment among judges and high internal consistency in the tool. Therefore, the rubric has the suitable construct validity, validated by the judges’ assessment, and high reliability, which justifies its usefulness in analyzing and assessing expository texts to be written by future university students and teachers in training.

This study aims to better understand training secondary and high school teachers require to develop scientific thinking skills in the areas of natural science (Biology, Chemistry, and Physics) and Mathematics. The study focuses on teachers of these disciplinary areas from public schools with an academic curriculum of the Heredia District of Education in Costa Rica. The study worked with 72 teachers of Mathematics and 88 teachers of natural sciences. The research used a naturalistic paradigm. The experimental design used a dominant qualitative approach, combined with a phenomenological study type. The study developed a questionnaire-type instrument to gather the information needed. This instrument consisted of a total of 12 questions in the following areas: pedagogical knowledge and use of technologies, and exploration of the degree of interest that teaching staff has in receiving training in disciplinary knowledge. The five categories used to analyze the teachers’ answers to the instrument were the following: general aspects of the practicing teacher, training interests in the disciplinary and pedagogical field, use of technologies, and challenges expressed by the teaching staff. Among the main findings of the study, the interest of the teaching staff to participate in updating processes in topics such as planning, mediation, and evaluation was evident, as well as training in the use of information and communication technologies. Also, it was determined that training in disciplinary areas should focus on the design of mediation strategies that allow the contents of the programs to be covered in an interdisciplinary and contextualized way. The teachers also showed interest in receiving training related to the design of evaluative processes that allow giving appropriate feedback to students, in terms of the degree of appropriation of scientific and mathematical thinking skills.
Representaciones del profesorado acerca de la enseñanza-aprendizaje de la asignatura “Paisaje y sostenibilidad” en aulas de secundaria en Galicia, España

Published: August 2020

The short curriculum titled Landscape and Sustainability, a new optional subject implemented in Galicia (Northwest of Spain), allows teachers to design their didactic programs with an important degree of autonomy when they do not have to be subjected to normative prescriptions. This circumstance allows analyzing and seeing the influence of the teachers’ social representations (SR) in the classroom around their teaching practice, the subject, and the type of educational context that favors innovation. This research article aims to answer that, also to identify how three secondary teachers conceive the innovation possibilities offered by this new subject, and to what extent they believe that this develops innovative educational attitudes in the didactic practice. It is a qualitative study whose data was obtained by applying three semi-structured interviews with open questions organized in blocks. These blocks were analyzed using the constant comparison method. The three teachers coincided with (1) an integral and critical view of the educational context; (2) they gave importance to the use of active methods and a critical approach as the key to success in their proposals; (3) the possibility of providing specific knowledge around the landscape supported by an interdisciplinary perspective; (4) they primarily aimed to have the students identify with their surroundings as a way to promote their social responsibility with those places; and (5) in two cases explicitly, and more indirectly in the third, they linked their proposals about the surroundings with heritage elements, pursuing different learning objectives. The analysis of these representations allows advancing the pre-eminence of the teacher’s disciplines over their interdisciplinary intention. Furthermore, it can be observed a tendency to make up students’ identities with places or heritage elements linked to the aesthetic, historical, or traditional factors.
Quantifying Sentence Variety in English Learners
Authors: Charpentier-Jiménez William
Published: August 2020

This article studies students’ use of sentence variety in an ESL writing course. The study includes three sentence features: (a) sentence types, (b) sentence combining, and (c) sentence patterns. Although sentence variety is part of the curriculum, the actual use of sentence structures has not been measured so far. By understanding students’ use of sentence structures, it is possible to propose valid curricular changes in the language program. This quantitative project has been carried out by analyzing 36 paragraphs written by students in the first writing course of a B.A. in English. The study included 433 sentences. Each sentence was examined individually. Data shows that 14.54% of the sentences presented a type of error. The types of errors included were the following: 12 fragments (2.77%), 29 fused sentences (6.69%), and 22 comma splices (5.08%). The remaining number of traditional sentences studied was 370 (85.45%). Results demonstrate that students favor certain types of structures and ignore others. Therefore, the demands of the curriculum and the written production of students lack coherence. Consequently, curricular changes must be incorporated to improve students’ written production.

Authors: Robles-Murillo Keylor
Published: August 2020

This essay’s main objective is to provide reflections on the following generating theme: “The teacher of today: someone who informs, inspires and educates.” Therefore, the proposed axis and title articulate ideas based on the relationship between didactics and the current context. Regarding medical issues, they are (a) the need to link the curricular contents with reality and the particular context in which each person who takes part in the educational process is located, and (b) the importance of vocation in teaching practice and the role of self-criticism as part of the feedback. The challenges identified are related to these three aspects: a) critical reflection; b) breaks with traditional paradigms; and c) teacher mediation. Finally, collective strategies to confront them are proposed, which are based on research, constructivism, and reflexive, horizontal, and dialogical planning.

For this purpose, quantitative non-experimental research was conducted, with a transversal and descriptive design to the applications and final reports of n=3,179 persons who submitted their applications during the academic years 2012-2018. This sample represents 30.97% of the total of 10,264 full-time academic teaching personnel, belonging to 132 federal institutions of TecNM. The major results found in the sample of n=3,179 from the sabbatical leave are: 34.22% (1,088) are women and 65.78% (2,091) are men; 71.98% (2,288) reinforce the elaboration of notes, training manuals, or books; the terminal efficiency is 88.44% (2,357 persons in a state of release); 36.7% (1,167) of the persons are aged between 58 and 68; 85.91% (2,695) carry out its activities in its institution; an average of 4.85% (498) of the total 10,264 full-time academic teaching personnel enjoy this benefit annually. It is also proposed that, during the sabbatical leave at TecNM, the participation of the younger generations is promoted, that the teacher mobility abroad is encouraged, and that participation in all its academic programs is leveled. Finally, it is concluded that the TecNM invests an important resource in the academic training of its professorship through the 18 academic programs of the sabbatical leave, to maintain its quality academic teaching personnel.
La comunicación y la interacción como aspectos clave de los entornos personales de aprendizaje: Perspectiva de estudiantes costarricenses de educación
Authors: García-Martínez José Antonio , González-Sanmamed Mercedes
Published: August 2020

Thanks to the proliferation of new information and communication technologies, and through increasingly global internet access, significant changes are being made in both the way we work in the classroom and in the relationships generated by the educational community; this calls for further development of communicative skills as key components of personal learning environments (PLE). This research aims to analyze the tools that Costa Rican education students know and use; it also examines the activities and mechanisms the students generate with their use to promote the communication processes to different levels. From a quantitative approach, and under a non-experimental design, information from a sample of 421 students is collected through a questionnaire composed of different scales. The main tools used to share information are social networks, email, and mobile apps; other resources are largely unknown. The main activities are linked to sending emails, communicating through chat applications, and using the Learning Management System (LMS). The vast majority of students (41.7%) indicate that they use the tools to share information and learn from others; although, it is worth highlighting that a high percentage (20%) does not use them for any of the options mentioned. It is necessary and urgent to stimulate and enrich students’ PLEs so that they can make the most of the resources available to facilitate their learning and develop their communication skills.
¿Camilo Fals Borda y Orlando Torres Restrepo? Diálogos y encuentros
Authors: Herrera Farfán Nicolás Armando
Published: August 2020

Este artículo recoge los elementos de sintonía ética, epistémica y política entre Orlando Fals Borda y Camilo Torres Restrepo, utilizando para el análisis el concepto guía de campo de Pierre Bourdieu. En el primer campo —el ético— se analiza la influencia del presbiterianismo costeño en Fals y la conversión al catolicismo de Camilo Torres. En el segundo campo —el epistémico— el ensayo plantea la evolución de ambos hacia la necesidad de pensar en una sociología latinoamericana crítica y descolonizada para construir una acción en favor del cambio social y político. El tercer campo de análisis es el político, donde se muestran las coincidencias en la perspectiva que asumen ambos sociólogos para estudiar las relaciones de dominación y explotación, articuladas a las dinámicas de violencia.

Authors: Canning Claire Ann , Freeman Kirsty Jane , Curran Ian , Boursicot Katharine
Published: August 2020

This article was migrated. The article was marked as recommended. The impact of the COVID-19 pandemic on the teaching and assessment of clinical skills continues to pose significant challenges for healthcare education providers worldwide. In March 2020 Duke-National University of Singapore (Duke-NUS) Medical School demonstrated how to design and implement clinical skills examinations (OSCEs) in the early phase of COVID-19. As governing bodies continue to revise restrictions to help 'flatten the curve', educational institutions have to undertake a rapid review of assessment practices and adapt to this ever-changing environment. This case study describes the risk-assessments and challenges faced when delivering high stakes OSCEs during the COVID-19 pandemic. We also describe successful mitigation strategies implemented to combat these risks, and how we also embraced and leveraged technology in a very creative way despite the restrictions and constrained environment.We describe and share practical guidance that may be of help or interest to healthcare education providers across all disciplines on how to effectively deliver clinical and procedural skills examinations that are authentic, valid and comply with the strict national COVID-19 restrictions implemented during this time.

The research of the temperature regime of permafrost soil performed in the FEM Models software packages by the Termoground module. In accordance with technical recommendations, the starting month for calculating permafrost is October. The period of drainage of thawed snow and rainwater is April – September. Thermophysical calculations of the base of the railway embankment, oriented on different sides of the world, have been performed. Changes in the temperature regime of the permafrost soil base in the construction site were researched. The calculation results showed uneven heating of the soil from the sunnier side in the embankment without the installation of a culvert with heads. There is an increase in the temperature of frozen soil from the warmer side, thawing bowls are formed. A numerical experiment shows the effectiveness of accounting for uneven insolation in the calculations at the design stage of construction projects.

Abstract The objective was to evaluate the chemical composition and in situ degradation of Maasai, Mombasa and Tanzania grasses belonging to the genus Panicum, at 22, 34 and 46 days after regrowth. The contents of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) were determined. For the evaluation of ruminal degradation, 4 g sample were placed in nylon bags and incubated in the rumen of a fistulated animal, for 6, 24 and 72 h. The experiment had a completely randomized design for chemical composition analysis and a split-split plot completely randomized design for in situ degradation, with means compared by Tukey test at 5%. There was an increase in the contents of DM (+ 1.69%) and NDF (+ 5.06%) (P <0.05) of the grasses at the highest cutting ages with reduction in the CP fraction. The potential degradation (PD) of DM, NDF and CP decreased with advancing age of grasses, with an increase in colonization time (0.69 h) and NDF degradation rate (1.14%/h). The increase in the post-regrowth age of the Massai, Mombasa, and Tanzania grasses increases the acid detergent fiber content and reduces the crude protein content, with a negative effect on the degradation of DM, PB and NDF. The management of these cultivars is indicated at 22 and 34 days post-regrowth to obtain forage with better nutritional value.
Influence of combined hydrolyzed collagen and maltodextrin as carrier agents in spray drying of cocona pulp

Abstract This work aimed to evaluate the effect of carrier agents containing maltodextrin and protein, represented by hydrolyzed collagen on the spray drying process of cocona (Solanum sessiliflorum Dunal), and on the properties of the resulting powders. We used pre-established proportions between the solids of cocona pulp and the carrier agents (P:CA), and among carrier agents themselves, maltodextrin and hydrolyzed collagen, (MD:HC). The process was carried out in a spray dryer at an inlet air temperature of 120 ºC. We prepared twelve feed solutions containing 20% of total solids, with P:CA ratios of 1:3, 1:4, 1:5 and 1:6, and MD:HC ratios of 0:100, 50:50, and 100:0. Solids recovery was obtained for the evaluation of the spray drying process. The cocona pulp powders were analyzed for moisture content, water activity, particle size distribution, mean particle diameter, chemical structure (FTIR) and color. For a P:CA of 1:6, for the sample formulated with hydrolyzed collagen only, solids recovery (96.2%) was much higher than that of the sample with maltodextrin only (39.2%). The chemical structure of cocona powders can be considered a sign of a good encapsulation process. The color of the cocona pulp powder was similar to that of the carrier agents. The formulation with highest content of hydrolyzed collagen improved the recovery of solids, guaranteed the cocona pulp encapsulation, and obtained fruit powders with bioactive properties.

ABSTRACT Noonan syndrome is an autosomal dominant genetic disease with different manifestations, including Speech, Language and Hearing Sciences ones. The authors describe the orofacial and myofunctional manifestations of an adolescent diagnosed with Noonan syndrome, by consulting the Speech, Language and Hearing Sciences record of a 17-year-old male patient, who underwent screening and speech therapy evaluation with a confirmed genetic diagnosis of Noonan syndrome. The results were qualitatively analyzed. The patient had a long facial type, with a disproportion between the lower and middle thirds of the face, ogival palate, and Mallampati class IV. A deficit in mobility and sensitivity of phonoarticulatory organs was also identified, absence of pathological oral and gag reflexes, decreased lip tone and tongue tension, increased speed chewing and inefficient grinding, functional swallowing for assessed consistencies, mild verbal and nonverbal apraxia, and moderate dysarthria. The results confirmed the presence of alterations in the speech-language organs, proving the relevance of the Speech, Language and Hearing Sciences evaluation in Noonan Syndrome, to allow adequate follow-up and treatment.

ABSTRACT Purpose: to describe the transgender people’s self-perception of voice. Methods: a total of 60 people participated in this cross-sectional study. They attended a reference outpatient center for the health of lesbians, gays, bisexuals, and transgender people. The data collection consisted of self-administered questionnaires, a participant’s profile questionnaire, and a voice self-assessment questionnaire. Results: most of the interviewees were young people who had never visited a speech-language-hearing therapist with the Public Health System (Sistema Único de Saúde); in general, they expressed interest in having such attention. The answers revealed an impact in the axes assessed, namely: “use of the voice in social life”, “mischaracterization of gender, due to the voice”, and “indication of dysphonia". Voice symptom characteristic of dysphonia was also identified in some people. Conclusion: transgender people are unsatisfied with their voices, which is an element that hinders the perception of the identified gender. It also has repercussions in their social, emotional, labor, and interpersonal lives. Hence, it is important to include speech-language-hearing therapy in the transgendering process, which is desired by most of the transgender people.

ABSTRACT Objective: to analyze the Brazilian scientific production in Orofacial Motricity from the annals of Brazilian congresses and journals in the field of Speech Therapy in the last six years. Methods: for this bibliometric review, data related to the year of production, type of study, Brazilian region/State, modality of higher education institution, event/magazine and presentation format were considered and tabulated. The data were discussed from the perspective of quantitative and representative values. Results: 1,299 studies have been published in the past six years. The highest production was achieved in 2014 and there was a predominance of original studies. Public higher education institutions produced more studies when compared to private ones. The event with the largest number of publications was the Brazilian Congress on Speech, Language and Hearing Sciences, and the journal with the largest number of publications was CEFAC Journal. The Southeast region was predominant in publications, followed by the Northeast region. Conclusion: the characterization of scientific production in orofacial motricity allowed us to verify that this is a consolidated area of activity, although it still requires advances.
Orthodontics and Endodontics: clinical decision-making
Authors: Consolaro Alberto , Miranda Dario Augusto Oliveira , Consolaro Renata Bianco
Published: August 2020

ABSTRACT Endodontically treated teeth may be moved, as endodontic treatment is not a contraindication for orthodontic treatment. Apical periodontal repair begins when the periapical or pulp lesion has completely resolved. This may happen immediately after treatment if the filling material causes little or no irritation of periapical tissues, and particularly if the material is fully contained within the canal. When it leaks, a foreign body granuloma forms and persists for some months or indefinitely, depending on the composition of the filling material. Materials containing calcium hydroxide with no resin components undergo phagocytosis and disappear in some months, as macrophages gradually remove them. Materials containing resins, silicone, ionomers, zinc oxide-eugenol, bioceramics or gutta-percha remain in the site and induce the formation of foreign body granulomas. Although this does not preclude tooth movement, patients should be followed up every three months using periapical images to control the position of the material in relation to the tooth apex. “Pseudo” overfilling may be avoided if permanent filling is delayed until the time when orthodontic treatment is completed.
