Motor Stereotypic Behaviors in Zoo Rhesus Monkeys: a Case Study of the Central Zoo, Kathmandu, Nepal
Authors: Sharma S. , Shrestha S. , Khanal L.
Published: June 2023

Motor stereotypic behaviors (MSBs) are a kind of repetitive behaviors performed by stressed animals and are more common in captivity. This study aimed to assess whether the MSB in captive rhesus monkeys varies between males and females, and with the extent of visitor-monkey interactions. A group of six rhesus monkeys (two adult males and four adult females; among females, two were rescued from the wild and two were captive-born) housed in the Central Zoo, Kathmandu Nepal were sampled in the study. Behavioral observations were done by focal animal sampling for 30 minutes in each session from 8:00 AM till 10:00 AM in the absence of visitors and 10:00 AM–12:00 PM in the presence of visitors. At every 10 minutes interval, the number of visitors around the cage and the level of visitor-monkey interactions were scanned. Pacing and bounce were the MSBs performed by the zoo rhesus monkeys. Females, especially the rescued ones, performed significantly more MSBs than the males. An increase in visitor-monkey interaction involved the monkeys into more begging and feeding, which in turn lowered the MSBs. The findings of this study indicate that interactive enrichment such as feeding and visitor-monkey interactions help to reduce MSBs in zoo monkeys.

Published: June 2023

Introduction. The emotional sphere of a personality is shaped under the influence of the system of public relations, which has its own specifics in the universities of the metropolis. Modern conditions have a limited amount of data on the development of the emotional and personal sphere and the possible risks of socio-psychological maladaptation of medical students studying in a megalopolis. For the first time, the emotional sphere of personality is considered in the context of manifestation of possible social maladaptation (conflict, stress, anxiety, neuroticism) of medical students in the conditions of the educational process in the megapolis. The aim of our work was to look into the emotional sphere of the personality of urban medical students in the conditions of the educational process drawing on their conflict, anxiety, neuroticism.
Materials and Methods. 105 medical students of various years of studies, living and studying in the megapolis, took part in the survey. A set of diagnostic techniques was used. The cross-sectional method was used to collect data. The results were processed using the SPSS program.
Results. Significant differences in the assessments of neuroticism among students of different years were found. There was a significant difference in stress assessments between first and last year students. The results differ significantly among students from different clusters based on cluster analysis of stress, anxiety and neuroticism assessments. The assessment of anxiety, stress and neuroticism makes it possible to talk about certain types of students in the context of maladaptation: type 1 – adapted, type 2 – have risks of development of maladaptation, type 3 – prone to maladaptation. It was also noted that the conflict of girls is expressed higher than the conflict of boys.
Discussion and Conclusion. The conclusions made by the authors contribute to the development of psychological and pedagogical knowledge that improves the training systems in a medical university. The materials of the article can be useful for teachers and administrators when interacting with students of all years of study. The assumption of a combination of all social maladaptation on a certain year of study is refuted, which indicates the need to continue the study.

Design and Analysis of Self-protection: Adaptive Security for Software-Intensive Systems
Authors:   ,   Linnaeus University, Faculty of Technology, Department of computer science and media technology, Skandylas Charilaos
Published: June 2023

Today's software landscape features a high degree of complexity, frequent changes in requirements and stakeholder goals, and uncertainty.Uncertainty and high complexity imply a threat landscape where cybersecurity attacks are a common occurrence while their consequences are often severe. Self-adaptive systems have been proposed to mitigate the complexity and frequent changes by adapting at run-time to deal with situations not known at design time.Self-adaptive systems that aim to identify, analyse and mitigate threats autonomously are called self-protecting systems.This thesis contributes approaches towards developing systems with self-protection capabilities under two perspectives. Under the first perspective, we enhance the security of component-based systems and equip them with self-protection capabilities that reduce the exposedattack surface or provide efficient defenses against identified attacks. We target systems where information about the system components and the adaptationdecisions is available, and control over the adaptation is possible. We employ runtime threat modeling and analysis using quantitative risk analysis and probabilistic verification to rank adaptations to be applied in the system in terms of their security levels. We then introduce modular and incremental verification approaches to tackle the scalability issues of probabilistic verification to be able to analyze larger-scale software systems.To protect against cyberattacks that cannot be mitigated by reducing the exposed attack surface, we propose an approach to analyze the security of different software architectures incorporating countermeasures to decide on the most suitable ones to evolve to. Under the second perspective, we study open decentralized systems where we have limited information about and limited control over the system entities. We employ decentralized information flow control mechanisms to enforce security by controlling the interactions among the system elements.We extend decentralized information flow control by incorporating trust and adding adaptationcapabilities that allow the system to identify security threats and self-organize to maximize trust between the system entities.
La risa de Eva: mito, historia y la subjetividad femenina en la novela El libro de Eva de Carmen Boullosa
Authors: O’Shanahan Edyta Andzel
Published: June 2023

This article offers a myth-critical analysis of the novel El libro de Eva (2020) by the Mexican writer Carmen Boullosa. Subversive reading of mythical narratives is one of the most interesting proposals of the post-structuralist criticism, centered on questioning the arbitrary determination of meanings. The analysed novel exemplifies the resistance to the hierarchical codification of symbols typical of the patriarchal ideology. At discourse level, the continuity between mythical and historical times underlines the importance of foundational narratives as part of collective memory and conceptual frameworks determining the course of history. The vindication of the figure of biblical Eve restores the right of the first woman to construct and articulate her own subjectivity.

Published: June 2023

Zinc finger CCHC-type containing 4 (ZCCHC4), RNA binding protein, has been reported to mediate rRNA methylation and affect tumor cell proliferation. However, the role of ZCCHC4 in the regulation of osteosarcoma (OS) remains unknown. ZCCHC4 was highly expressed in OS tissues and cell lines. Overexpression or silencing of ZCCHC4 promoted or inhibited cell proliferation, epithelial-mesenchymal transition (EMT), and motility. Additionally, we proved that ZCCHC4 facilitates OS progression through upregulating integrin β1 (ITGB1). In the animal model, ZCCHC4 knockdown reduced OS tumor growth and metastases in vivo. Our findings showed that ZCCHC4 promoted the progression of OS through upregulating ITGB1 and suggested that inhibition of ZCCHC4 could be a novel therapeutic strategy for OS.
Development of shear deformation in lath martensite of medium alloy steels under tension
Authors: Teplyakova L. A. , Kashin A. D. , Kunitsyna T. S.
Published: June 2023

Evolution of shear deformation in steel with the structure of tempered martensite was studied under active tension. Purpose of the work was to identify the patterns of deformation development at the scale-structural levels: package, plate, fragment of a package and a lath. The authors investigated the deformation relief formed at different stages of plastic deformation by optical, transmission and scanning electron microscopy. Quantitative characteristics of the deformation relief were measured: shear strength (P), distance (X) between the shear traces and their length. Statistical processing was carried out, the average values and relationship with the degree of plastic deformation were determined. It was established that development of shear deformation in the lath component of martensite occurs with the formation of two subsystems of shear traces: thin and coarse. Subsystems of thin traces are formed from the very beginning of plastic deformation. Appearance and evolution of the subsystem of coarse traces correlates with formation of the first (long) neck in the sample, and it is the main mechanism leading to the localization of plastic deformation on the sample scale. The places of localization of rough shift are the border areas of the laths and fragments of the package. Connection between localization of subsystems of coarse shear traces and formation of a fragmented dislocation structure were revealed. The values of the average shear power in thin  and coarse  traces do not depend on the degree of local plastic deformation of the sample in the entire range of deformation degrees and remain constant until destruction ( = 0.1 μm and  = 0.3 μm).
Deoxidation capacity of aluminum in ferromanganese carbon-containing melts
Authors: Makrovets L. A. , Samoilova O. V. , Mikhailov G. G.
Published: June 2023

Deoxidation (reduction of oxygen concentration dissolved in liquid metal) is an integral part of steel production technology. For obtaining deeply deoxidized metal, mainly aluminum is used at metallurgical enterprises. It should be taken into account that alloying elements of steels and alloys under certain conditions can act as deoxidizing elements, contributing to the complex nature of the deoxidation process. Almost all steels contain manganese in one concentration or another. The study of interaction processes in the Fe – Mn – Al – O – C system at steelmaking temperatures is of applied importance. In this paper, a thermodynamic analysis of the deoxidation ability of aluminum in oxygen-containing iron-manganese melts was carried out. At the same time, influence of carbon on course of the deoxidation process was taken into account. In the study, it is effective to use a technique for constructing the solubility surface of components in metal (SSCM) – a diagram that connects the compositions of liquid metal with the compositions of conjugated non-metallic phases. In the course of this work, oxygen solubility isotherms in the Fe – Mn – O system were calculated for the temperature range of 1550 – 1650 °C. For the Fe – Mn – Al – O – C (1600 °C) system, composite sections of the SSCM were constructed at fixed carbon concentrations in steel [C] = 0; 0.1; 0.4; 0.8 and 1.2 % (hereafter by weight). It is shown that with the simultaneous presence of manganese and aluminum in an oxygen–containing iron-based melt (at industrially significant concentrations [Al] = 0.001 – 0.010 % and [Mn] – less than 1.0 %), aluminum in the liquid metal will act as a deoxidizing agent, and corundum inclusions will be formed as interaction products. Complex deoxidation by aluminum and manganese with the formation of spinel is typical only for manganese-alloyed steels, where the concentration of manganese is more than 1.5 %.
Social-Ecological Knowledge Integration in Co-Design Processes: Lessons From Two Resilient Urban Parks in Chile
Authors: Gaete Macarena
Published: June 2023

Cities worldwide face multiple social and ecological challenges, such as climate change and its impacts. Adapting and transforming our urban environments is urgent to improve their resilience to uncertain scenarios. These challenges require renewed urban solutions and force us to rethink their design processes. Multiple actors are involved in such processes, coming from different sectors, and sometimes having conflicting agendas and knowledge backgrounds. Many of these processes can be considered co-design processes, with actors interacting to improve the design quality, legitimacy, and feasibility. Many conceptualise cities as social-ecological systems and public spaces are their subsystems. A collaborative approach to designing public spaces contributes to integrating the social-ecological knowledge from the public, private, and citizen actors. The question remains: How is sometimes conflicting social-ecological knowledge integrated into public space co-design processes? We study two large-scale urban parks in Chile. We framed them as social-ecological systems and analysed their co-design processes. This study aims to provide insights into the difficult-to-grasp phenomena of knowledge integration in co-design processes. We analysed these cases in previous studies. Now we provide insights into social-ecological knowledge integration in co-design processes. Although framed in Latin America, the findings may be helpful elsewhere.

Role of microbiome in development of systemic inflammatory response syndrome and sepsis (review)
Authors: Khomyakova Tatyana I. , Khomyakov Yuri N. , Makarova Olga V.
Published: June 2023

Sepsis is a life-threatening organ dysfunction caused by a disturbed response to infection. Its development is preceded by systemic inflammatory response syndrome, which is the overall inflammatory response of the body to severe lesions. The role of opportunistic pathogens in the development of systemic inflammatory response syndrome and sepsis may be known, but the value of the intestinal microbiome remains underestimated in this context.
Experimental models are widely employed to study the role of the microbiome in the development of sepsis. Animal models of sepsis are created by disrupting the barrier function of the host intestine through cecal ligation/puncture, installation of an ascending bowel stent, and intraperitoneal feces injection. Toxemia is reproduced by the injection of lipopolysaccharides, peptidoglycans, lipoteichoic acid, CpG DNA, zymosan, and synthetic lipopeptides.
The review systematized data on the role of the cell wall or membrane components of gram-positive and gram-negative bacteria, which are representatives of the intestinal microbiome in the pathogenesis of systemic inflammatory response syndrome and sepsis.

Authors: Cole Hank M. , Yeck William L. , Benz Harley M.
Published: June 2023

The Machine Learning Asset Aggregation of the Preliminary Determination of Epicenters (MLAAPDE) dataset is a labeled waveform archive designed to enable rapid development of machine learning (ML) models used in seismic monitoring operations. MLAAPDE consists of more than 5.1 million recordings of 120 s long three-component broadband waveform data (raw counts) for P, Pn, Pg, S, Sn, and Sg arrivals. The labeled catalog is collected from the U.S. Geological Survey National Earthquake Information Center’s (NEIC) Preliminary Determination of Epicenters bulletin, which includes local to teleseismic observations for earthquakes ∼M 2.5 and larger. Each arrival in the labeled dataset has been manually reviewed by NEIC staff. An accompanying Python module enables users to develop customized training datasets, which includes different time-series lengths, distance ranges, sampling rates, and/or phase lists. MLAAPDE is distinct from other publicly available datasets in containing local (14%), regional (36%), and teleseismic (50%) observations, in which local, regional, and teleseismic distance are 0°–3°, 3°–30°, and 30°+, respectively. A recent version of the dataset is publicly available (see Data and Resources), and user-specific versions can be generated locally with the accompanying software. MLAAPDE is an NEIC supported, curated, and periodically updated dataset that can contribute to seismological ML research and development.

Published: June 2023

La presente investigación plantea como objetivo comparar el modelo de valoración a través de Flujo de Caja Descontado empleando el Costo Promedio Ponderado de Capital (WACC) y el Modelo Valor Presente Ajustado (APV), en la empresa Apple Inc., a fin de determinar cuál de estas metodologías resulta más apropiada, considerando que la mayoría de las empresas norteamericanas del sector tecnología presentan altos niveles de endeudamiento, pero tienen perspectivas de crecimiento sostenido. El estudio se apoya en teorías relacionadas a la valoración de empresas, modelo del Flujo de Caja Descontado, modelo del Valor Presente Ajustado (APV) y la empresa Apple Inc. Metodológicamente la investigación tiene un enfoque cuantitativo, de tipo documental y descriptivo con un diseño bibliográfico. La información para realizar las valoraciones se obtiene de las páginas web morningstar.com y bloomberg.com. Los resultados evidencian que la valoración con el método APV es más favorable para la empresa evaluada. Por lo que se concluye que los escudos fiscales añaden valor a la empresa, pues la deuda incrementa el costo financiero, pero reduce los impuestos al generar una base menor de cálculo, por tanto, para compañías con elevado endeudamiento, resulta más favorable que se valoren con el método APV.

La investigación analiza dialécticamente el proceso comunicacional, entre directivos y docentes en educación primaria en una institución pública de Madrid, España. La investigación de tipo cualitativa, se sistematiza mediante el estudio de casos, estructurado en cuatro fases: preparatoria, trabajo de campo, analítica e informativa. Los informantes clave son dos (2) directivos y tres (3) docentes de educación primaria. Los datos, se recolectan mediante un guion de entrevista semi-estructurado con preguntas abiertas y notas de campo, los hallazgos emergentes, se triangulan y saturan con el fin de lograr la valoración dialéctica de la situación en estudio. Del análisis dialéctico, se desprenden las siguientes debilidades: proceso comunicacional poco asertivo y defensivo, falta de buenos canales de comunicación, poca confianza para expresar las ideas y opiniones y debilidades en los intercambios comunicativos. Resulta pertinente profundizar en la formación y concienciación del personal respecto al proceso de interacción comunicativa en la inmediatez de los centros escolares.
Características de las tareas de la práctica profesional contable que pueden ser afectadas por la automatización de procesos: validación de metodología y análisis en un caso de actividad gerencial
Authors: Budiño Gabriel , Asuaga Carolina
Published: June 2023

El trabajo muestra la primera etapa de una investigación sobre las características de las tareas que realiza la profesión contable más factibles de ser sustituidas por la incorporación de la Automatización de Robotización de Procesos en el marco de la transformación digital. La hipótesis, en concordancia con la posición doctrinaria principal, es que el uso de tecnologías para la robotización y automatización de procesos tiene un fuerte impacto en la profesión, ya que múltiples tareas se verán interrumpidas, desplazadas o deconstruidas, siendo las habilidades básicas requeridas reemplazables y existiendo cambios significativos de la forma en que se entrega el valor. Se muestran los resultados del primer estudio de caso cuyo objetivo principal fue la validación de la metodología a aplicar. Se releva mediante entrevista las tareas realizadas por un cargo gerencial de la filial uruguaya de una empresa internacional clasificándolas en manuales o cognitivas, rutinarias y no rutinarias. Luego las tareas se codifican de acuerdo con el tipo de valor que se ofrece y las habilidades requeridas. Los resultados validan la metodología y muestran que, acorde a lo esperado para un cargo gerencial, casi dos tercios de las tareas son del tipo cognitivo no rutinario, que las habilidades requeridas para llevar adelante la mayoría de las tareas asociadas no se ven afectadas significativamente, y que para la mitad de las tareas no hay cambios en la forma en que se genera el valor. Asimismo, queda de manifiesto, la necesidad de mayor formación sobre el potencial de las tecnologías de automatización robótica de procesos, así como de sus costos, para evaluar correctamente los beneficios asociados y realizar una adecuada planificación de su utilización. Finalmente, los autores señalan la importancia de determinar cómo la automatización se vincula a objetivos, políticas y estrategias asociadas a la transformación digital de las organizaciones.

La adopción del comercio electrónico en las PyMEs
Authors: Maita Guédez Maryianela del Carmen
Published: June 2023

Este artículo presenta los resultados de una investigación documental, cuyo propósito fue identificar los factores que intervienen en la adopción del comercio electrónico en las Pequeñas y Medianas Empresas (PyMEs). Se examinó, analizó y contrastó diversos estudios sobre esta temática para encontrar respuesta a la pregunta planteada. Cada uno de los trabajos seleccionados responden a contextos muy particulares, así los resultados demuestran que diversas son las causas que motivan a las PyMEs a incorporarse a la comercialización de bienes y servicios a través de los medios digitales, por tanto, no existe una receta única. No obstante, se pueden establecer algunas imperativas dominantes como las organizacionales, preparación (readiness), conocimiento (awareness), innovación, presión ambiental o externa, facilidad de uso, beneficios percibidos, confianza en el medio, entre otros. Se concluye que gracias a las características de los nuevos gerentes que han crecido y se han formado en un mundo competitivo, donde las Tecnologías de Información y Comunicación (TIC) dominan el entorno, cada vez se hace más proclive el uso del comercio electrónico en las PyMEs, con la salvedad que esto no representa la panacea de los problemas organizacionales, frente a los cambios de la época, y como tal no puede creerse que con tan solo incorporarse al mundo del comercio digital se obtendrán beneficios por sí solos, hay que saber gestionar para lograr extraer su valor. El reto no es implementar tecnologías sino transformar organizaciones a través de un gerenciamiento adecuado con su apoyo.

Biological tissues possess a high degree of structural complexity characterized by curvature and stratification of different tissue layers. Despite recent advances in in vitro technology, current engineering solutions do not comprise both of these features. In this paper, we present an integrated in silico–in vitro strategy for the design and fabrication of biological barriers with controlled curvature and architecture. Analytical and computational tools combined with advanced bioprinting methods are employed to optimize living inks for bioprinting-structured core–shell constructs based on alginate. A finite element model is used to compute the hindered diffusion and crosslinking phenomena involved in the formation of core–shell structures and to predict the width of the shell as a function of material parameters. Constructs with a solid alginate-based shell and a solid, liquid, or air core can be reproducibly printed using the workflow. As a proof of concept, epithelial cells and fibroblasts were bioprinted respectively in a liquid core (10 mg/mL Pluronic) and in a solid shell (20 mg/mL alginate plus 20 mg/mL gelatin, used for providing the cells with adhesive moieties). These constructs had a roundness of 97.6% and an average diameter of 1500 ±136 μm. Moreover, their viability was close to monolayer controls (74.12% ± 22.07%) after a week in culture, and the paracellular transport was twice that of cellfree constructs, indicating cell polarization.

Nowadays, in addition to the hard skills like academic knowledge of new graduates, other soft skills of management such as Career Maturity (CM), Information-Seeking Behavior (ISB), Entrepreneurial Efficacy (EE), Problem-Solving Skills (PSS), and Managerial Skills (MS) are also required by the company owner as they will be useful in real-life work management. The objectives of this study are: 1) to investigate the current competencies of CM, ISB, EE, PSS, and MS of undergraduate students in Thailand, 2) to investigate the different competencies of CM, ISB, EE, PSS, and MS across different gender, faculties, and grade levels. This study uses an online questionnaire to collect data from 569 undergraduate students from Thailand. The result shows that the reliability of the data collecting tool is acceptable (Cronbach’s alpha was at 0.87) and the current findings further reveal that the total competencies of CM, ISB, and MS are different by gender but on the other way, total competencies of all 5 which means to CM, ISB, EE, PSS, and MS are different by faculties and grade levels. The information from this study can make instructors or teachers develop a modern classroom that can increase competitiveness for undergraduate students and prepare them to be qualified to apply for future employment.

Studies focusing on subjective assessment of risk of obstructive sleep apnea in general population are sparse. The purpose of this cross- sectional study was to assess the risk of obstructive sleep apnea in a population visiting dental Out Patient Department. Three hundred consenting participants between the age group of 18-65yrs reporting to the dental OPD were enrolled in the study. Polysomnography is the gold standard of diagnosis of OSA, however, due to cost and elaborate procedure other methods of diagnosis and risk assessment were used as tools. STOP BANG questionnaire was evaluated for the participants and grouping was done into high, moderate and low-risk OSA patients. Anthropometric patient measurements, including Body Mass Index (BMI), age, neck circumference and gender, were recorded. Blood pressure was assessed by a digital blood pressure instrument to check the systolic and diastolic levels. Data was collected and statistically analyzed. The BMI for males was 24.5±3.9, and for females, it was 24.5±4.6. The mean neck circumference in males was higher (14.4±1.2) compared with females (13.1±1.4). 4.1% of males had a high risk of neck circumference, whereas 3.7% of females had a high risk. 16.1% of males reported hypertensive systole compared with 8.2% of females and 23.9% of males reported hypertensive diastole compared with 18% of females. Risk assessment of OSA based on STOP-BANG scoring revealed that 63.6% of the total study population were at low risk of developing OSA, 32% at high risk and, 4.4% of the study population at very high risk of developing OSA. Males were at higher risk than females. OSA has a high prevalence and a higher tendency to remain underdiagnosed due to a lack of awareness amongst the population as well as dental and healthcare professionals. There can be an essential role of a dentist in identifying the risk factors of OSA and referring those patients to sleep, specialists. In the long run, the dentists' early diagnosis of OSA patients may prevent OSA complications and aid in managing the condition.

To evaluate the anxiety level among the undergraduate dental students during and after endodontic treatment.

In this study questionnaire was prepared with 15 questions based on stress level, anxiety, and work load among dental undergraduates during endodontic treatment. The questionnaire were circulated and filled by participants in a self-report method.

: 70% of students reported that canal location is the reason for the fear of endodontic treatment, but their anxiety starts before the treatment begins. Around 60% of students have moderate level of anxiety before starting the treatment and 70% manifest sweating during the endodontic treatment. Access cavity preparation of the posterior teeth and oral fluid control were considered as the factors to feel stressed during the procedure among 51% and 29% of the undergraduates respectively.

: According to this study, higher level of anxiety were seen among the undergraduates and therefore, the stress control must be focused before starting the procedure, access cavity preparation and while handling endodontic instruments.

The available shade guide system in dentistry includes Manual and Digital. Although there is lot of research going on better system to choose dental shade but still there are many factors including source of light illuminating the tooth, the characteristics of tooth and the observer viewing the tooth which needs to study further. In this study, a comparative analysis is made between the Manual and Digital shade guide systems.

: The objective of the study is to record the manual (subjective method) and a digital shade (Objective method) of 500 subjects by two observers (Prosthodontist 1 {P1} and Prosthodontist 2 {P2}).

: 500 patients having a complete set of anterior teeth with sound maxillary central incisors were selected for the study. Manual shade selection (Vita 3D Master) of 50% of subjects is made by P1. Then P2 does shade selection of the same subjects by digital method (Vita Easy Shade Advance) and records the deviation of values including ∆E, ∆L, ∆C, and ∆h by digital shade guide from the manual shade as recorded by P1 using verification mode of Digital shade guide. Recording of shades and deviation values is done for the remaining 50 % of patients by role reversal between P1 and P2.

: The kappa correlation values for Hue value and chroma when P1 records manually and P2 documents shade by digital shade guide include 0.26, 0.42, and 0.13 indicating fair, moderate, and slight to no agreement respectively. The kappa correlation values for Hue value and chroma when P2 records manually and P1 records shade by digital shade guide include -0.08, 0.51 and 0.12 indicating no agreement, moderate and slight to no agreement respectively.

It is advisable to use technology to overcome the errors of subjectivity. Due to edge loss with a spectrophotometer, especially in the incisal and cervical region, a combination of digital and manual systems always comes in handy when deciding on a particular shade or shade map.

The important requisite of root canal treatment is that root canals should be free of microorganisms, which plays major role in success of treatment. Usage of intracanal medicament inside root canals will help in the reduction of microbes inside the root canal system. Intracanal medicaments also help in reduction of inter-appointment pain.

A survey was conducted among dental practitioners and non-endodontic specialists of Tamilnadu to evaluate the knowledge and awareness of intracanal medicaments. The questionnaire had 20 questions related to intracanal medicaments and its usage in endodontic practice. The questionaire was distributed among randomly chosen 100 dental practitioners (both general and other specialists except endodontists.) of Tamilnadu, working in various government or private hospital or clinics. The answers obtained were analysed using descriptive analysis.

In the current study, we observed that the awareness about intracanal medicaments among the practitioners was satisfying. However, they should update the knowledge about the intracanal medicaments.

The results of current study insist more continuing dental education programs are needed; with active participation of practitioners to keep them update about intracanal medicaments.
