Endodontic treatment in the management of cracked tooth
Authors: Kwak Youngjun
Published: July 2024

In many cases, endodontic treatment is unnecessarily performed while managing cracked tooth. However, there are many cases where it is unclear whether endodontic treatment should be performed or not during thetreatment of cracked tooth. One good way is to attach the final prosthesis with a temporary cement and then have a lot of conversations with the patient about their condition. Through this process, the timing of final ce-mentation or endodontic treatment can be determined. Of course, even if we do so, endodontic treatment may be performed in some cases, so the management of cracked tooth is inevitably called endodontic treatment originated treatment.

Authors: Kim Ji Hoo , Ryu Ji-Won , Ahn Jong-Mo , Park Hyun-Jung
Published: July 2024

This case report aims to inform about the side effects of oral appliances and discuss ways to improve them. The patient is a 68-year-old female with occlusal changes caused by using an oral appliance that does not cover all teeth. She has been treated with an oral appliance for one year to improve her pain in the Temporomandibular Joint (TMJ) area. After treatment, the pain in the TMJ was released, but occlusion changed. Because of her left posterior open bite, she was advised to avoid wearing an oral appliance and to exercise for masticatory muscle strengthening. After one year and six months, occlusal stability improved. It is recommended to wear a complex type of oral appliance that covers all teeth as much as possible only during sleep to avoid side effects.

Published: July 2024

Dental pulp stem cells are mesenchymal stem cells derived from the dental pulp tissue of permanent or deciduous teeth. Especially, stem cells from human exfoliated deciduous teeth (SHED) have an enhanced capacity than adult pulp stem cells counterpartfor self-renewal (proliferation) and multilineage differentiation, being able to generate dentin/pulp-like complexes, neural cells, skin cells, chondrocytes, and osteogenic cells, among others. Their accessibility from routine dental procedures and lack of ethical concerns make SHED an attractive stem cell source for regenerative therapy. This paper reviews current preclinical and clinical research on the tissue regenerative potential of SHED-based therapies. In preclinical animal models and clinical trials, SHED transplantation have shown promise for bone regeneration and repair, neural regeneration, myocardial infarction treatment, inflam-matory bowel disease, renal injury, liver fibrosis, diabetes mellitus, erectile dysfunction, skin wounds, muscle injury, and other con-ditions. Early-phase human trials further indicate the feasibility, safety, and efficacy of SHED based cell therapy for various disease introduced before. However, therapeutic effects from SHED injections vary greatly depending on cell source, delivery method, dose, and disease model or condition. Additional translational medicine studies for elucidating key therapeutic mechanisms of SHED and methodological advances in cell processing and delivery are needed to improve consistency. If the remaining challenges are addressed through rigorous research, SHED cell therapy may become versatile clinical (dental) materials for tissue repair andregeneration across a wide range of organs and disease states.
Necessity of Anatomy Education for Dental School Students Utilizing 3D and Virtual Reality Technologies: A Narrative Review
Authors: Lee Yeon-Hee
Published: July 2024

Members of dental academia are eager to embrace innovative tools for anatomy education. The proliferation of technological resources has facilitated the integration of virtual systems into dental and medical education. This is considered paramount for communicating the anatomical knowledge essential for safe and competent medical practice. Among these tools, three-dimensional (3D) anatomy models, virtual reality (VR) simulations, and haptic technologies are pivotal for educating students and training healthcare professionals. This narrative review discusses these topics based on published outcomes from the past decade, emphasizing their potential in anatomical learning and clinical practice, particularly during the COVID-19 pandemic. Substantial interest and positive impacts have been reported by educators and students regarding the utilization of 3D VR. 3D VR enables precise and high-resolution representations of organ structure, vascular formation, and nerve distribution. It enriches anatomical, clinical, and radiological learning and familiarizes individuals with the anatomical and radiological features of real patients. Furthermore, 3D VR ensures the continuity of anatomical and surgical training through online platforms, making the strategic deployment of these devices especially pertinent during quarantine. Therefore, dental education and clinical applications using 3D VR, augmented reality, and haptic technology are expected to become an unstoppable trend.
Alignment for alveolar bone graft and improvement of transverse discrepancy in adult patients with unilateral/bilateral cleft lip and palate
Authors: Hong Mihee
Published: July 2024

Since 2019, orthodontic treatments of cleft lip and/or palate have been supported by the Korean National In­surance System. Based on the national claim data, more than 30% of fixed orthodontic treatments were provided to adult cleft palate patients. Their maxillary arches frequently were deformed and collapsed, and sometimes needed arch coordination for alveolar bone graft. Therefore, the treatment progress for two patients with uni­lateral/bilateral cleft palate was introduced, presenting improvement of inter-arch horizontal disharmony and dental alignment with fixed orthodontic appliances to enable iliac bone graft and implant prosthesis.
Bone graft for alveolar cleft by using demineralized dentin matrix
Authors: Ku Jeong-Kui , Baik Jin-A
Published: July 2024

Autogenous bone grafts remain the standard for cleft alveolus surgery despite absorption tendencies and donor site complications. DDM, derived from teeth, demonstrates promising osteoinductive properties comparable to autogenous bone. This paper aims to introduce and discuss cases of bone graft for cleft alveolus utilizing demineralized dentin matrix (DDM) derived from teeth, highlighting the outcomes and potential advantages of DDM in cleft alveolus reconstruction. A nine-year-old patient underwent cleft alveolus surgery with bilateral bone grafting. To address volume limitation of DDM, the surgical procedure involved harvesting bone from the anterior iliac crest. Postoperative radiographic assessments at nine months revealed favorable bone integration in the cleft region. The study advocates for further exploration of DDM applications in clinical recommends.
Clinical limitations and its solutions of the digital clear aligner treatment
Authors: Bae Gi-Sun
Published: July 2024

The digital clear aligner is widely used due to the convenience and efficiency of simultaneously manufacturing the entire aligner used in treatment with a single setup. However, due to the characteristics of clear aligners, which make it difficult to effectively transmit orthodontic force to the teeth compared to traditional brackets, the teeth do not move as planned, resulting in repeated refinements and increased treatment periods. The following measures have been proposed to solve these problems:1. Partial production of Clear aligner: Manufacturing the entire aligner not all at once but in stages, typically 8-10 at a time, allows for more precise management of the individual tooth movement. Additionally, adjustments can be made promptly if treatment does not go as planned.2. Direct 3D printing of clear aligners: Direct 3D printing offers the possibility of creating more efficient aligners that adhere more closely to the teeth than vacuum-formed ones. Moreover, effective tooth movement can be achieved by adjusting the aligner's thickness or designing structures to apply orthodontic forces as required.3. Digital hybrid treatment: Using 3D-printed brackets with two strands of NiTi wire allows for rapid and accurate tooth movement with gentle force. In particular, the ability to manufacture clear aligners and 3D-printed brackets together in a single digital setup enables various clinical applications. This not only shortens the treatment period but also allows for better treatment results.
A study on regional distribution and changes in the Korean dentist workforce
Authors: Yim You-Bin , Jeon Ji-Eun
Published: July 2024

Purpose: Despite previous research showing that there is an excess of dentists in Korea, there are demands to increase the number of dentists, with some local governments requesting the establishment of dental colleges and dental hospitals. Therefore, this study aims to propose long-term policy directions regarding the supply and demand of dentists in Korea by analyzing the distribution of dentists relative to the population and the current status of dentists by region.Methods: This study used public data. WHO's key indicator, active dentists per 100,000 population, was calculated by year, and differences in active dentists by region were analyzed using ANOVA.Results: From 2012 to 2022, the average annual rate of the number of active dentists per 100,000 people was 2.39%, which was higher than the average annual population growth rate(0.10%)(Table 1). The regional averages were ‘gu’ 66.52±55.78, ‘si’ 38.50±10.87, and ‘gun’ 29.91±7.35, showing a significant difference (p<0.0001), confirming the existence of a gap.Conclusions: The supply and demand of health care professionals is the most important factor for the stable operation of the health care system. To resolve regional differences, it is desirable to utilize existing dentists rather than creating new dentists.
The importance of individualized and multiple landmarks for the identification of facial nerve trunk: a narrative review
Authors: Pang KangMi , Kuk Su Kyung , Choi Eunhye
Published: July 2024

The identification of the facial nerve trunk(FNT) is an important step in surgical procedures involving the parotid gland and adjacent structures to minimize the risk of inadvertent nerve damage which leads to facial muscle paralysis. Despite the availability of various anatomic landmarks such as the tragal pointer, posterior belly of digastric muscle, tympanomastoid suture, digastric branch of facial nerve and styloid process, no single landmark is perfect, with variations observed between individuals. Therefore, a comprehensive knowledge of facial nerve anatomy is essential for FNT identification. In this review, we tried to introduce clinically meaningful methods for the localization of facial nerve trunk. The preference of landmark could be changed by the major of the surgeon or the location of the tumor of the patients. Understanding the characteristics and drawbacks of the landmarks and choosing multiple landmarks that were convenient for surgeon would be necessary.

Binary mixture convection in a horizontal channel under the Soret effect action
Authors: Stepanova Irina
Published: July 2024

The mathematical model describing stationary flow of binary liquid mixture is under consideration. The exact solution of the equations of convective heat and mass transfer is constructed for the special form of the functions of temperature and concentration. All possible statements of boundary value problems are studied in order to analyse thermal diffusion separation of binary mixture in a long horizontal channel with rigid walls. It is discovered that only one of the statements (at inhomogeneous heating of both rigid walls) leads to feasible results. With the help of the constructed solution for the mentioned boundary value problem the effect of layer thickness, given flow rate and action of gravity force on the separation process, is analysed.

Published: July 2024

An approach is implemented in this article to analyze the decay rate of nonlinear beams according to the Euler?Bernoulli equation in the context of rheological viscoelastic damping deformations taking into account the neutral type delay. The interaction between viscoelastic and neutral type delays is discussed as our main aim to support a rapidly developing literature. Using the energy method and constructing an appropriate Lyapunov functional, under certain conditions on the kernel and neutral delay terms, we show that despite the destructive nature of delays in general, a very general decaying energy for the problem was obtained.

Authors: Centeno Rodrigo Pozzer , Fagundes Paloma de Mattos , Costa Nilson Luiz , Padilha Ana Cláudia Machado , Schardong Bianca Jupiara Fortes
Published: July 2024

Pesticides have the function of protecting agricultural crops through phytosanitary treatments, helping increase productivity to feed an ever-growing population. They exist in a globally competitive market, where pesticide companies, resellers, and agricultural cooperatives are responsible for the sales and distribution to the final consumer, in this case the farmer. In this context, this research aims to characterize the agricultural pesticide sector and the agricultural marketing system in the Northwest and Southwest Mesoregions of the State of Rio Grande do Sul, Brazil. This research consisted of a bibliographic research followed by a field survey of 40 companies, including owners and pesticides resale managers (32) and agricultural cooperatives (8). The results show a marketing system aimed at Rio Grande do Sul conducted mainly through the sale of supplier companies to resellers and agricultural cooperatives, which resell them to the farmer. The tendency of the agricultural pesticides market is to stabilize, even with the decline of the sector in Brazil in successive years, with a current resumption of growth, much of it driven by national and multinational supplier companies that invest in countries like Brazil.

Authors: Семенов Виталий Адольфович , Морозов Сергей Вячеславович , Шерстенников Игорь Александрович
Published: July 2024

В настоящее время цифровые модели зданий активно применяются в международной и российской практике реализации строительных проектов. Для их автоматизированной оценки ведется работа по переводу национальных стандартов и сводов правил, предусматривающих требования к безопасности зданий, сооружений и процессов, в так называемый «Реестр требований». Однако декларируемый переход к машиночитаемым стандартам с целью повышения качества проектной документации и автоматизации процедур проверки сталкивается с серьезными методологическими проблемами. Их причиной является отсутствие понимания, каким образом должны представляться стандарты, и какие математические методы и программные инструменты осуществления проверок необходимы для этого. Вместе с тем, подобные проблемы системно и успешно решаются на протяжении четверти века в рамках дисциплины инженерии требований, для чего разработаны соответствующие стандарты, методологии и инструменты. В работе обосновывается применимость дисциплины к области строительства, а также дается интерпретация ее ключевых принципов. На основе сравнительного анализа существующих инструментов проверки описывается перспективный подход к спецификации и валидации требований к цифровым моделям в строительстве с использованием формальных методов.

Published: July 2024

La acuicultura es actividad dirigida a producir y engordar organismos bajo condiciones controladas de especies desarrolladas en el medio acuático, siendo la tecnología biofloc una alternativa viable, aprovechando los residuos orgánicos e inorgánicos a través de microorganismos heterótrofos presentes en el agua y empleando mejor los recursos hídricos. El objetivo de este estudio fue evaluar la producción de tilapia roja (Oreochromis sp) criada en un sistema con tecnología biofloc (TBF), utilizando un diseño no experimental descriptivo empleándose un total de 5000 alevinos de tamaño promedio inicial de 1,5 cm y peso de 0,6 g, monitoreando constantemente los parámetros fisicoquímicos (pH, amonio, nitrito, nitrato, sedimentación, oxígeno disuelto, y temperatura). Se midieron aspectos como incremento de peso (IP), Consumo total de alimento (CTA), Consumo diario (CD), Factor de conversión alimenticia (FCA). Los resultados evidenciaron que los parámetros fisicoquímicos del agua en este sistema se encuentran dentro de los rangos recomendados para el cultivo de tilapia. Se observó que en algunas semanas durante el crecimiento del pez hubo un bajo índice de conversión alimentaria con valores de 0.33, 0.35, 0.53, 0.67, 0.79, 0.91, 0.99, influyendo de esta manera en la reducción de los costos de producción, teniendo en cuenta que entre más cercana al cero sea el FCA mayor será la eficiencia del uso de alimento, por lo que en este caso la implementación del sistema no fue el óptimo (por volumen de producción) debido a que no se dio un bajo índice en todo el cultivo, generando problemas de rentabilidad.
Enhancing mobile robot navigation: integrating reactive autonomy through deep learning and fuzzy behavior
Authors: López-Velásquez Julián , Acosta-Amaya Gustavo Alonso , Jimenez-Builes Jovani Alberto
Published: July 2024

Objective: This study aimed to develop a control architecture for reactive autonomous navigation of a mobile robot by integrating Deep Learning techniques and fuzzy behaviors based on traffic signal recognition. Materials: The research utilized transfer learning with the Inception V3 network as a base for training a neural network to identify traffic signals. The experiments were conducted using a Donkey-Car, an Ackermann-steering-type open-source mobile robot, with inherent computational limitations. Results: The implementation of the transfer learning technique yielded a satisfactory result, achieving a high accuracy of 96.2% in identifying traffic signals. However, challenges were encountered due to delays in frames per second (FPS) during testing tracks, attributed to the Raspberry Pi's limited computational capacity. Conclusions: By combining Deep Learning and fuzzy behaviors, the study demonstrated the effectiveness of the control architecture in enhancing the robot's autonomous navigation capabilities. The integration of pre-trained models and fuzzy logic provided adaptability and responsiveness to dynamic traffic scenarios. Future research could focus on optimizing system parameters and exploring applications in more complex environments to further advance autonomous robotics and artificial intelligence technologies.

El impacto ambiental se determinó con la huella gris fue de 377,9 ± 14,7 L/m3 de jugo por la demanda química de oxigeno (DQO); 255,3 ± 11,2 L/ m3 de jugo de demanda bioquímica de oxígeno (DBO5); 29,6 ± 3,1 L/m3 de jugo en el fósforo y 10,6 ± 1,8 L/m3 de nitrógeno, lo que indica que su vertimiento causaría daños medioambientales severos.  Sin embargo, por ser orgánico se determinó la capacidad de reducción de la carga orgánica de manera biológica, alcanzando un porcentaje de biodegradabilidad del 90% a las 55 horas, lo que indica que sería rápidamente aprovechado por los microorganismos. Finalmente, con los resultados de la caracterización fisicoquímica y teniendo en cuenta la Norma Técnica Colombiana NTC-ISO 5167, el jugo de fique clasifica como enmienda o acondicionador orgánico no húmico líquido, sin embargo, a pesar que las concentraciones de los macronutrientes N, P2O5, K2O no cumplen con el valor mínimo, es factible que los cultivadores de Fique puedan avanzar hacia una economía circular, mediante el aprovechamiento del jugo de Fique como enmienda y reemplazo de fertilizante en su propio cultivo y complementar la fertilización con el abono orgánico que también se puede obtener del bagazo de Fique u otra fuente.

Los metales pesados son contaminantes que se generan por diferentes actividades siendo una de estas el vertimiento de aguas residuales por parte de las industrias en cuerpos de agua lo cual representa una gran amenaza para la biota acuática y terrestre, así como la salud. Estos contaminantes son persistentes, bioacumulables y no biodegradables, generando un efecto negativo en la cadena trófica de la zona de influencia. El níquel es un metal pesado que se emplea en diferentes tipos de industrias como las productoras de baterías. Este genera diferentes efectos nocivos en el cuerpo humano, como en el sistema cardiovascular o el digestivo cuando hay exposición en grandes cantidades. El objetivo del presente estudio es emplear la Ingeniería de Procesos Asistida por Computador (CAPE por sus siglas en inglés) para modelar una columna operativa a escala industrial tendiente a la adsorción Níquel (II) en solución acuosa aprovechando la biomasa de Theobroma cacao L. Por consiguiente, se empleó el software Aspen Adsorption para llevar a cabo múltiples simulaciones de una columna de adsorción utilizando diversas configuraciones a nivel industrial, con el objetivo de realizar un análisis de sensibilidad paramétrica. En los resultados obtenidos, se evidencia que el modelo Langmuir- modelo cinético de resistencia lineal global (LDF) utilizado para simular la columna de adsorción en la eliminación de Níquel (II) logra eficiencias de hasta un 95.8%. Las mejores condiciones para la simulación en la columna de adsorción fueron un caudal de entrada de 300 m3/día, una altura del lecho de 5 m y una concentración inicial de 2000 mg/L. Además,se observó que el aumento del caudal de entrada condujo a una disminución en el tiempode ruptura y saturación del proceso, mientras que, aumentar la altura del lecho presenta unincremento en el tiempo de ruptura y saturación. Por otro lado, la concentración no afecto demanera significativa a la eficiencia del proceso.

Covid-19 is an unpredictable event that impacts the economic sector. Micro, Small and Medium Enterprises (MSMEs) play a major role in the Indonesian economy. However, of the 59.9 million MSMEs in Indonesia, the success rate of selling products through digital platforms is only 4%. The obstacles commonly encountered by MSMEs are the lack of knowledge of running an online business as much as and the unpreparedness of workers to use the internet as much. Whereas online media provides a promising market. Therefore, the application "BUSION: Business Solution" which helps MSMEs to find digitization services according to their budget in order to present attractive product visuals and a good social media management system. The method used in this research is the latest literature study so that it can produce accurate and solution outcomes. Then the various features for MSMEs contained in this application are looking for photographers, social media management, and product design. This application also has regional features so that MSMEs can find the best services closest to their current location. In addition to maximizing digitalization and expanding the market, this application can also support the government's 'Go Digital' program to restore the national economy after the co-19 pandemic. The conclusion of this research is that it is proven that the BUSION application is a platform that is feasible to develop in Indonesia in order to revive the national economy after the Covid-19 pandemic.

أصبحت المعاملات الإلكترونية حقيقة قائمة في العالم المعاصر، وهي نتيجة التطور السريع في مجال وسائل التقنية الحديثة ولكنها تواجه إشكالية تتعلق بالإثبات ، في حين هي بحاجة إلى شروط غير التقليدية المتعارف عليها حتى تتماشى مع التطور التقني نتيجة الطفرة السريعة لزيادة حجم المعاملات التجارية كافة والالكترونية خاصة، عليه فان هذه الدراسة تهدف الى البحث عن نطاق قبول المحررات الإلكترونية في الإثبات وفقا قانون التوقيع الالكتروني والمعاملات الكترونية العراقي وقانون التوقيع الكتروني المصري، حيث ان المشرعين حددا نطاق الاثبات بالمحررات الكترونية، وتم استبعاد جملة من المعاملات من نطاق قبولها في الاثبات وإن كان التطور الالكتروني واستعمال وسائل الكترونية في الواقع تقضي بغير ذلك .

This study evaluates the diversification benefits of investing in traditional and alternative/renewable energy Exchange Traded Funds (ETFs) using the VAR-ADCC-GARCH model to analyze yields, correlations, and volatilities. The results demonstrate that alternative/renewable energy ETFs not only offer higher average returns but also significantly reduce portfolio risk compared to traditional energy ETFs. The research underscores the distinct investment dynamics between the two ETF segments, highlighting the advantages of incorporating renewable energy assets into diversified portfolios. These findings support the inclusion of environmentally-conscious investment strategies that effectively balance risk and return, emphasizing their importance for investors aiming to optimize their portfolios in line with sustainable practices.

As highlighted by Pop & Georgescu (2024), the Romanian academic literature concerning municipal bonds is sparse, while the investigations regarding the factors that can influence the sub-sovereign bond trading at Bucharest Stock Exchange is quasi non-existent, to the best of authors’ knowledge.
The present paper continues the work of Pop & Georgescu (2024) by trying to identify which of the public available information regarding various interest rates and Bucharest Stock Exchange (henceforth BVB) indices returns influence the trading activity of municipal bond market segment.
The correlations presented within this paper imply that the modest profile of municipal bond segment at BVB is related to a relative small number of individual investors that dominate the transactions, using mostly observed data to decided when to trade and what to trade. The scarce correlations that appear in relation with the trading volume and trading value point toward the idea that only a small portion of the listed municipal bonds are owned by individual investors.

"The purpose of this research is to examine the cognitive schemas activated in sexual situations as mediating factors in the relationship between endometriosis symptoms and sexual distress. N=173 women diagnosed with endometriosis, who had a sexually active status during data collection, took part in the research. The survey consisted of a demographic data sheet, the ENDOPAIN-4D, the Questionnaire of Cognitive Schema Activation in Sexual Context and the Female Sexual Distress Scale - Desire/Arousal/Orgasm questionnaires. The results of the Structural Equation Modeling technique indicate that the mediation model does not show a good model fit with our data. We do not see this explanatory power regarding the relationship between pelvic pain and sexual distress sexual, or between bowel pain and sexual distress. Based on the complex indirect effect, maladaptive cognitive schemas mediate the relationship between pain during sexual intercourse and sexual distress, as well as the relationship between other symptoms of endometriosis and sexual distress.
