Authors: Kim Moo-Kyeong , Kim Hyun-Je , Kim Dong-Hyuck , Lee Eui-Seok , Lim Ho-Kyung
Published: July 2024

MRONJ (medication related osteonecrosis of the jaw) is a disease characterized by necrosis of the jaw that occurs after administration of anti-resorptive or anti-angiogenic drugs. However, etiology and effective treatment methods of MRONJ are not yet clearly identified. In this study, a systematic review was conducted to investigate the effects of pentoxifylline and tocopherol on MRONJ. A total of 5 clinical studies using pentoxifyllie and tocopherol in MRONJ patients among the papers registered in Pubmed/medline were reviewed. Pentoxifyllie and tocopherol were used for therapeutic purposes in 32 patients, and the mean age was 68 years for men and 74.21 years for women. Of the 32 patients, 20 patients were stage 2, 11 patients were stage 3, and one patient was stage 0. In the most cases, the triggering factor was extraction. All patients com-plained of pain in the lesion area before drugs administration. The average follow-up period was 10.6 months. After drugs administration, 29 patients (90.6%) showed improvement in symptoms in terms of bone exposure and pain. Administration of pentoxifylline and tocopherol in MRONJ may improve symptoms of pain and bone exposure. However, it seems that additional studies on the appropriate use and dose, timing and duration of administration are needed.

Authors: Cho Han-A , Shin Hosung
Published: July 2024

This study was conducted to measure patient safety of dental outpatients and to identify high-risk areas in dental care. A survey was conducted with 400 people aged 19-64 who had used a dental institution within the past 3 years. The Primary Care Patient Measure of Safety (PC-PMOS) questionnaire was used as a dental safety patient measurement tool. 19 domains and 46 questions of PC-PMOS were analyzed, and negative responseswere classified into risk areas in dental care. 10 of the 46 items of PC-PMOS had a negative response rate of 20% or more. The questions with the highest percentage of dissatisfied were 'when they referred me to another hospital, there was a waiting list (50.9%)', 'if necessary, you could receive hospital services outside of the regu-lar operating hours of the hospital (38.1%)'. The dental patient safety score was higher for male and for house-holds with an average monthly income of 8 million won or more (p<0.05). Findings of this study suggest that it is necessary to prepare a dental patient safety management system in that patient safety management improves the quality of dental care. In addition, standardized dental patient safety management indicators are essential for monitoring and improvement of patient safety and quality in dentistry.

Authors: Hwang Ilkwang , Park Hee-Kyung
Published: July 2024

Objective: To identify the status of dental services in Korean correctional institutions and suggest improvement measures.Methods: We surveyed 31 out of 32 dental public health doctors working at correctional institutions under the Ministry of Justice, to analyze the status of dental treatment provided in 47 such institutions. We also examined the dental public health doctors' awareness of dental services.Results: Thirty-seven percent of institutions had no radiation devices available for diagnosis, and 80.9% of institutions complained of a lack of radiation diagnostic equipment. In 78.7% of institutions, dental treatment by external doctors was performed regularly, and 93.5% of dental public health doctors thought that they were necessary. On the other hand, the need for a dental officer (including a dental public health doctor) was rated lower (74.2%). Among dental public health doc-tors, 83.9% said that the environment to deal with emergency situations was not sufficient, 64.5% were concerned about the disadvantages caused by medical accidents, and 61.3% thought that relief measures were insufficient. Futher, 66.0% of respondents said it was difficult to receive medical treatment at external hospitals if necessary. Moreover, 74.2% of dental public health doctors said working in correctional institutions was rewarding, and many doctors reasoned that it was notrewarding because they regretted not being able to provide high-quality treatment. As for the most urgent task to improve dental treatment for inmates, increasing the number of dental assistants and changes in the consciousness of medical services and medical officers were suggested, among others, such as establishing a dental hospital for inmates, expanding equipment and materials for dental treatment, and recruiting external (invited) dentists.Conclusion: Dental public health doctors oversee dental services at Korean correctional institutions, and further research is urgently needed to improve these services. Improvements in dental services at correctional institutions should include increas-ing dental staff including assistants and external dentists, and expanding the equipment and materials for dental treatment.

Management of malocclusion with pre-fabricated myofunctional appliance in the primary dentition
Authors: Shin Jonghyun
Published: July 2024

The most common malocclusion presented during primary dentition are anterior crossbite and deep overbite.If the primary dentition does not show severe skeletal discrepancy, it is possible to treat malocclusion using pre-fabricated myofunctional appliance that is easily applied to children. By improving the malocclusion in the primary dentition, normalization of the oral muscle function can be induced. In addition, the normal occlusion of the primary incisor region and ideal position of the lips can make a desirable occlusal relationship at the transition of incisors. If factors such as growth pattern, patient cooperation, and post-treatment maintenance are carefully judged and implemented, the interceptive treatment of primary dentition can contribute to normal growth and development.

Authors: Lee Joo-Young , Kim Hyo-Jung , Jung Hoi-In , Kim Baek-Il
Published: July 2024

Although studies reporting the efficacy of mouth rinse against SARS-CoV-2 have been continuously published, it is chal-lenging to select literature through qualitative meta-synthesis or quality assessment of the study. Therefore, this study aims to systematically review the efficacy of mouth rinse against SARS-CoV-2 using the scoping review method and to provide the latest information. Literature search on electronic databases (PubMed, Scopus, and Cochrane Trials) was conducted. After establishing liter-ature inclusion and exclusion criteria, two independent researchers were selected literatures. Of the 15 articles were included in this scoping review, 11 were in vitro studies, and four were in vivo studies. The ingredients tested in these studies were povidone-iodine, chlorhexidine, hydrogen peroxide, essential oils, and qua-ternary ammonium compounds, and they showed various efficacy against SARS-CoV-2. Despite the relatively limited evidence from the included studies, the use of mouth rinse has the potential to reduce the viral load of SARS-CoV-2. In particular, povidone-iodine is expected to be the most effective against SARS-CoV-2, given the evidence so far.
The Role of Clinician for Improving Quality of Antemortem Data in Dental Identification
Authors: Lee Sang-Seob
Published: July 2024

Forensic identification using the dental characteristics is one of the most powerful scientific methods of iden-tification. Since dental identification is performed by comparing the dental characteristics between antemortem and postmortem data, success or failure is determined according to the quality and quantity of antemortem data.Antemortem data is ultimately produced and managed by clinicians, therefore, clinician is also one of the im-portant factors for successful identification. In this study, the types of antemortem data which is used for dental identification and methods to improve the quality of antemortem data, were reviewed. And suggestions were given to clinicians for increasing the success rate of identification. It is expected that through this mutual com-munication between forensic odontologists and clinicians, the identification rate of missing persons in Korea can be improved.

Published: July 2024

This study aimed to investigate the effect of different conditions on the implant stability test (IST) value of three-unit implant bridges. Fifteen pairs of specimens were prepared. Two internal conical-type implants were placed in artificial bone using a torque of 35 to 45 Ncm. Three-unit monolithic zirconia bridges (Perfit ZR) were fabricated using CAD-CAM. Im-plant Stability Quotient (ISQ) values were measured for each implant. IST value was measured under different conditions: healing abutment, without cementation, with cementation, one prosthesis unscrewed, and two prostheses unscrewed. The results showed statistically significant differences according to the conditions (p <0.05). The lowest IST level was observed in the groups tested on healing abutment and the prosthesis without cementation. The highest IST level was observed in the groups with cemented prostheses. There was no significant difference according to screw loosening. IST values for all groups measured above 79, indicating high stability with consistent tendency. The present study implied that IST values could be used as a reference restrictedly for assessing implant stability and conditions on bridge-type prostheses.

Published: July 2024

Osteoarthritis in the temporomandibular joint (TMJ) affects surrounding soft and hard tissues including cartilage, sub-chondral bone, and synovial membrane, causing TMJ remodeling and articular cartilage abrasion. When degenerative bone changes worsen in some patients with osteoarthritis, facial skeletal remodeling occur such as chin deviation, malocclusion. In patients with TMJ osteoarthritis, it is important to expand the joint space and decompress it. When pathological changes in the joint are observed, minimally invasive treatment such as intra-articular injection and arthrocentesis can be performed. An intermaxillary traction appliance can be applied for a short period of time to patients with TMJ osteoarthritis with oc-clusal changes. The purpose of this report is to review the case using arthrocentesis and intermaxillary traction appliance along with conservative treatment in a patient with unilateral posterior open bite caused by temporomandibular disorder(osteoarthritis), and to report the importance of appropriate diagnosis and treatment of temporomandibular disorder.

Authors: Kim Ji Rak
Published: July 2024

Osteoarthritis (OA) is common disease that can lead to severe pain and dysfunction in any joint, including the temporomandibular joint (TMJ). The treatment strategy for TMJ OA aims at reducing pain, preventing the progression of condylar bone destruction, and restoring joint function. Conservative therapy including nonste-roidal anti-inflammatory drugs, occlusal splint, and physical therapy, and arthrocentesis are the most common treatments for TMJ OA. These therapies are effective in most cases in relieving the signs and symptoms.
Position Papers on MRONJ(Medication related osteonecrosis of the jaw), What has changed?
Authors: Kwon Tae-Geon
Published: July 2024

Antiresorptives, such as bisphosphonate, denosumab, are widely prescribed drugs for the treatment of osteoporosis, os-teopenia, malignant bone metastases, multiple myeloma and Paget`s disease. They have therapeutic efficacy for controlling bone pain and reducing skeletal related events including the pathologic fractures. However, it was reported that the develop-ment of osteonecrosis of the jaw(ONJ) could be related to antiresorptive treatments. It was first defined as Bisphosphonate-related osteonecrosis of the jaw in 2007 American Association of Oral and Maxillofacial Surgeons(AAOMS) position paper. This was changed to Medication-related osteonecrosis of the jaw(MRONJ) in the AAOMS position paper 2014. Thisposition paper was updated recently in May 2022 and contains revisions to disease definition and management strategies at “AAOMS position paper on MRONJ-2022 update”. The important changes in clinical implications are as follows; 1) In the definition, immune modulators (such as Romosozumab) were included with potential medications related with osteo-necrosis of the jaw (ONJ), 2) Operative therapy was included for all stages (1, 2 and 3) in treatment strategies, 3) Formerly mentioned drug holiday before surgical procedure to prevent MRONJ was not identified in 2022 AAOMS position paper. Most of the statements in AAOMS 2022 position paper were based on strict literature reviews and changes were made if there is little evidence to suggest the specific diagnosis or therapeutic options. Understanding the changes compared to the previous position papers is important in selecting adequate treatment strategies for MRONJ.
New oral rehabilitation method in disabled patients using implants - Implant surveyed crown retained RPD -
Authors: Yoo Soo-Yeon
Published: July 2024

The marginal bone loss (MBL) and survival rates of dental implants in patients with disabilities were comparable to those reported for patients without disabilities. Despite the viability of implants for disabled patients, socioeconomic issues and general condition of disabled patients prevent them from receiving as many implants as they require in edentulous areas. However, because of the difficulty of adaptation, the use of complete den-tures (CD) is not the preferred treatment option for those with disabilities. Consequently, disabled patients canbenefit from the convenience and lower cost of an implant surveyed crown retained removable partial denture(IC-RPD). The survival rates and MBL of those implants in IC-RPD have already established the clinical acceptability as a treatment option for patients who are not disabled. IC-RPD can be future implant treatment strategies for disabled patients.

Published: July 2024

As the accessibility of dental treatment for the disabled has improved and the need for oral care has emerged, implant restoration has been adopted as one of the treatment methods for restoring the missing teeth in these patients. However, considering the characteristics of disabled patients and the level of cooperation should beconsidered. It is necessary to check for medication and consider any systemic diseases that may be affected byinvasive surgery. In particular, patients taking antiplatelet, anticoagulant, or osteoporosis drugs, or in a state of organ transplantation, invasive implant surgery should be more cautious. In this article, the considerations for various medical history and characteristics of several types of disability would be discussed.

Cracked Tooth Diagnosis Methods and Limitations
Authors: Kim Sunil , Shin Su-Jung
Published: July 2024

It is difficult to diagnose differently from other diseases if patients have pain due to cracked teeth. The main reason why cracked tooth diagnosis is difficult is that there is no diagnostic method that can visualize and quan-titatively evaluate the degree and depth of cracks. Bite tests, methylene blue staining, transillumination tests, and x-ray tests can be performed to diagnose cracked teeth. In this paper, I will explore the pros and cons of the methods used so far and discuss their effectiveness in diagnosing cracked teeth.
Clinical Application of Quantitative Light-Induced fluorescent(QLF) device in the Diagnosis of cracked teeth
Authors: Son Sung Ae
Published: July 2024

As social interest in health increases, interest in oral health and preservation of natural teeth are also increasing. The hard tissues in the oral cavity undergo physical changes as age increases. One of the changes is the progress of tooth cracks in natural or restored teeth. These cracks are commonly encountered in daily clinicalpractice but often confuse the operator due to its difficulties in diagnosis and therapeutic access. Diagnosing acracked tooth has been a chanllenge to dental clinicians. For the diagnosis of a cracked tooth, the quantitative light-induced fluorescent (QLF) device, which is capable of detecting fluorescent reactions of the tooth with visible light (405nm), has been introduced as one of the methods for observing tooth cracks. Specific metabolites of microorganisms that penetrate through the crack’s line react with specific autofluorescence to 405nm visible light emitted from the QLF device. These fluorescent image provided by the QLF helps to observe the location of the crack during the diagnosis of a cracked tooth and helps the patient’s dental record. The QLF images provided a magnified image as well as a fluorescent im-age that could identify the location of the crack existing outside the tooth, around the restoration, and inside the cavity after removal of the restoration by a simple process of capturing images. This report shows the process of diagnosis of a cracked tooth using a QLF device by observing three separate cases which can help clinicians to understand this process.

Published: July 2024

Objectives: The purpose of this study is to analyze the reasons of the claim rejections and denials compensated by dentalrelated the Industrial Accident Compensation Insurance (IACI) that is operated by the Korea Workers’ Compensation and Welfare Service (COMWEL).Methods: We collected 803 claims from one consultant who responded to dental-related medical inquiries commissioned by the Daegu and Gyeongbuk Workers’ COMWEL from January 2021 to May 2023. We analyzed the approval status and the reasons for non-approval, based on the reviewed response materials and dental online medical consultation data.Results: Among the initial and supplementary compensation applications, there were 79 cases with insufficient examina-tions, 72 cases with incomplete records, 19 cases with errors, 148 cases due to pre-existing conditions, and 6 cases where the applicant was ineligible for medical benefits. The reasons for re-evaluation after data supplementation included 122 cases of inadequate examinations, 76 cases of incomplete records, 24 cases with logical errors, 11 cases with insufficient photographs, and 57 cases for a combination of these reasons.Conclusions: In the context of industrial injury compensation claims, the denial of claims often arises from missing or incomplete dental records, diagnostic omissions, or logical inconsistencies between records, diagnoses, and treatment plans. Therefore, it is essential to ensure accurate medical records, appropriate examinations, and evidence-based diagnosis. Spe-cial attention should also be given to the collection of clinical data, including photographs.

Authors: Chun Yanghyun , Kim Taeseok
Published: July 2024

Proportion of the elderly is steadily increasing, and accordingly, number of elderly care facilities for elderly support is also rising up. However, number of nursing caregivers for welfare services is not following the increasing tendency of elderly care facilities. In this study, we surveyed the oral care work fatigue and satisfaction of the nursing caregivers in elderly care facilities, and what the nursing caregivers think to improve quality of welfare services. Also, we analyzed the factors that have relation with self-care ability of the elderly patients in elderly care facilities to help patients care of nursing caregivers.
The above can be summarized as results and proposals as follows.
1. Most of the nursing caregivers were engaged in oral healthcare. Satisfaction of oral healthcare work tended to be high, but fatigue of work and need to improve oral healthcare procedure were also high.
2. To make improvement, nursing caregivers argued that regular oral checkup by dental specialists in the facility is needed, followed by regular education of oral health care to nursing caregivers. This was contrary to the opinions of administrators, who rated regular education of oral health management to administrators as the most important one.
3. Nursing caregivers in elderly care facilities were actively performing oral healthcare, but they felt fatigue of work and argued needs to improve working environment. To achieve this, muti-disciplinary approach should be considered, including improvement of oral healthcare speciality, systemic improvement to ease the healthcare burden on nursing caregivers, and to bridge the gap of opinion between nursing caregivers and administrators in elderly care facilities.
A Novel Approach to Treat Dental Implant-related Maxillary Sinusitis via Intentional Oroantral Fistula: Case Series
Authors: Park Jae-Hyeong , Kim Jin-Wook , Yoon Hyun-Woo , Lee Sung-Tak
Published: July 2024

The recent increase in dental implant placement and advances in maxillary sinus bone grafting have improved the oral environment and greatly benefited patients, but there has also been an increase in dental implant-related maxillary sinusitis. Implant-related maxillary sinusitis is a form of odontogenic maxillary sinusitis, which usually presents as a chronic form of maxillary sinusitis. While acute (4 weeks or less) maxillary sinusitis is treated with removal of the associated implant, decontamination of the contaminated bone graft materials, and antibiotics. However, implant-related maxillary sinusitis is most often diagnosed as a chronic maxillary sinusitis condition that has been present for more than 12 weeks and should be treated similarly to chronic maxillary sinusitis. Treatment for chronic implant-related maxillary sinusitis is accompanied by endoscopic sinus surgery (ESS) to open the obstructed maxillary ostium. ESS is usually performed by referral to an ENT specialist and can be a burdensome treatment for patients due to the discomfort of surgery and the risk of orbital and cranial complications.In this case series, we aim to help dentists treating chronic implant-related maxillary sinusitis by reporting the complete cure of implant-related maxillary sinusitis without performing ESS by creating an intentional oroantral fistula after removing the causative implant. We also report important pathologies that should be differentiated from typical implant-related maxillary sinusitis.

Authors: Lee Eun-jin , Park Hee-Kyung
Published: July 2024

Burning mouth syndrome (BMS) refers to a condition characterized by pain sensations such as burning or tingling, or sensory disturbances in the tongue or oral mucosa without any specific local or systemic cause for more than 3 months. This study retrospectively investigated the clinical characteristics of 248 BMS patients (217 women, 31 men, mean age 64.7±11.2 years). Treatment outcomes were assessed using the Numeric Rating Scale (NRS). Parafunctional habit control education, saliva substitute, and counselling for psychological stability were implemented at the first visit, resulting in a significant reduction in NRS scores at the second visit. Medication such as clonazepam or zinc supplements were administered from the second to fourth visit, leading to a significant reduction in NRS scores compared to the initial visit. The various treatment options can be applied to alleviate the symptoms of BMS. Forty-eight patients (19.35%) exhibited serum zinc concentration of 70μg/dL or lower. A well-designed clinical study with a large number of patients is needed to compare the therapeutic effects between underlying conditions, medications, and nutritional supplementation including zinc.

A Cascade PID Controller Design with Cuckoo Optimization Algorithm (COA) and Input Shaping (IS)
Authors: Yalçıner Durukan Büşra , Durukan Halit Murat , Çankaya İlyas
Published: July 2024

From past to present, Proportional-Integral-Derivative (PID) controllers stand out as the most widely used types of controllers. Due to the high-performance requirements, experimentally determined controller coefficients necessitate the application of modern optimization techniques. In this study, Ziegler-Nichols, Chien-Hrones-Reswick, and Cohen-Coon methods, which allow parameter calculation through the open-loop system's step response method, were compared with the Cuckoo Optimization Algorithm for PID controllers designed for a brush-commutated DC motor with unknown parameters in the Matlab environment. The comparison was based on Integral of Absolute Error (IAE), Integral of Square Error (ISE), Integral of Time-weighted Absolute Error criterion. Similarly, the performance of the Cuckoo Algorithm was discussed in terms of stability margins and stability peaks. In this comparison, it was observed that the PID controller optimized with the Cuckoo Algorithm operated with high proportional and integral coefficients to minimize the cost function, resulting in overshoot in the system response. Input shaping, a commonly used method in open-loop control of both brushed and brushless DC motor systems, was integrated into the system to mitigate this overshoot. The hybrid controller achieved the best performance in terms of IAE, ISE and ITAE in the system response, with less overshoot compared to the other mentioned methods.

Authors: Аришин Семен Васильевич , Гринченко Александр Иванович , Шило Александр Владимирович
Published: July 2024

Обсуждаются проблемы и перспективы применения открытых стандартов IFC (Industry Foundation Classes – ISO 16739) и IDS (Information Delivery Specification), разработанных авторитетным альянсом buildingSMART International, для представления цифровых информационных моделей объектов капитального строительства и спецификации требований к ним. Данные проблемы представляются актуальными в связи с попытками разных ведомств и организаций формализовать нормативные документы строительной отрасли РФ, разработанные и доступные только на естественном языке. Переход к машиночитаемому представлению позволит обеспечить математически строгую и высокоавтоматизированную валидацию проектной документации на следующем уровне развития технологий информационного моделирования (ТИМ). В работе приводится краткое введение в стандарт IDS, а также описывается web-редактор требований, специфицируемых на его основе. Особое внимание уделено конкурентным преимуществам редактора, связанным с контекстной помощью при заполнении форм требований пользователями, не являющимися специалистами в области открытых стандартов.

Published: July 2024

В статье рассматриваются проблемы, связанные с переносом BIM-технологий в область разработки ландшафтных моделей (LIM-моделей). Проблемы демонстрируются на примере композиционных характеристик ландшафта. В качестве примера композиционных характеристик использована концепция визуально-пространственных единиц. Современные BIM-модели основаны на использовании наборов данных стандарта IFC. Сделан вывод, что Стандарт можно использовать при условии, что композиционные характеристики рассматриваются как функциональные характеристики набора данных IFC. Однако, алгоритм онлайн вычисления композиционных характеристик на сегодня неизвестен. Определение композиционных характеристик на сегодня возможно только после построения визуальной 3D-модели. В результате композиционная BIM-модель лишается преимуществ параметризации. Таковы проблемы переноса BIM-технологий в область архитектурно-ландшафтного проектирования.

Рассматривается возможность улучшения действующей системы ценообразования и сметного нормирования в строительстве и получения максимального экономического эффекта с помощью интеграции технологий информационного моделирования (далее – ТИМ) в строительный процесс. Применение ТИМ позволит точно рассчитывать стоимость будущего строительства, автоматически формировать смету, а также на любом этапе проекта проверять наличие номенклатуры включенных в проект ресурсов. С помощью анализа возможностей основных сметных программ выявлены следующие проблемы: взаимодействие участников проектного процесса, разнообразие и закрытость форматов данных, взаимосвязь конструктива и сметных регламентов, взаимодействие сметной системы и ТИМ, передача результата проектирования, подготовка кадров, и предложены пути их решения. Предложен подход к выбору оптимального программного продукта для реализации 5D в ТИМ.

Reducing the use of fossil fuels and increasing the use of renewable resources is essential in minimizing climate change. As the world progress towards using more renewable resources for energy and other products, biomasses will be crucial to this transition. Utilizing biomass as efficiently as possible is therefore necessary, and this relies on the types of biomasses used in addition to the actual production methods. Biomass residues like corn stover and eucalyptus sawdust could be valuable sources of renewable energy. Corn stovers are herbaceous agricultural residue, whereas eucalyptus sawdust is a woody residue that can be processed into different fuels that have a variety of applications. Pelleting is the cheapest technique for producing fuel pellets that can be employed for heat and electricity production. The overall qualities of pellets can be enhanced by blending biomass materials with different qualities and using additives, such as binders. Corn stovers and eucalyptus sawdust are large waste streams which are more often discarded and underutilized. To ascertain the suitability of these biomass residues as blends on pelletization, determination of their properties through characterization is, therefore, a necessity. The focus of this research was to determine the analysis of both their ultimate and proximate composition of eucalyptus sawdust and corn stover and the higher heating values. These properties were determined using ASTM standards. The results obtained for proximate analysis of corn stover were moisture content, volatile matter, ash content, and fixed carbon were 5.92%, 74.99%, 5.21%, and 20.13%, respectively, and 3.70%, 84.66%, 3.22%, and 12.11% respectively for eucalyptus sawdust. Corn stovers’ ultimate analysis for carbon, hydrogen, nitrogen, sulphur and oxygen were 39.54%, 5.70%, 1.38%, 0.07%, and 53.32%, respectively, and 47.16%, 4.97%, 0.08%, 0.03%, and 47.76%, respectively for eucalyptus sawdust. Higher heating values were 17.38 MJ/kg and 17.93 MJ/kg for corn stover and eucalyptus sawdust, respectively. These results indicate that corn stover and eucalyptus sawdust can be blended together, improving the properties of corn stover pellets, such as higher heating value and reduction of ash content.
Analítica predictiva como apoyo en la salud pública: Modelos de pronóstico en salud mental con series de tiempo

Published: July 2024

La salud mental ha sido declarada por la Organización Mundial de la Salud (OMS) como un asunto de interés prioritario en la salud pública internacional. En el caso particular de Colombia, se ha destacado la importancia de la atención a la salud mental incluyendo el fenómeno del suicidio. En este sentido, los entes reguladores han buscado alternativas que solucionen o contribuyan a la mitigación de esta problemática. En dicho contexto, se hace pertinente realizar contribuciones académicas en torno al desarrollo de herramientas que faciliten la toma de decisiones de los entes gubernamentales, por ejemplo, a través de la formulación de modelos de pronóstico que permita identificar tendencias y patrones de comportamiento de los intentos de suicidio.
 Este artículo contribuye con esta brecha en la literatura para el caso particular de los casos de intentos de suicidio en la ciudad de Medellín, Colombia, a través del uso de analítica prescriptiva. Este trabajo presenta el ajuste, validación y comparación de tres diferentes modelos de series temporales, bajo criterios de mínimo error de pronóstico. Los modelos comparados incluyen aproximaciones paramétricas, Holt-Winters y Box-Jenkins; y se identifica que, para los datos analizados, el modelo paramétrico de componentes aditivos cúbico estacional con errores ARMA(0,5) es el que presenta menor error de pronóstico. Los resultados indican que este modelo logra capturar las tendencias del fenómeno, y que tiene un bajo nivel de error para la proyección en cuanto a tendencias cercanas, pero que no logra dar respuesta a los cambios repentinos en la estructura como los que ocurrieron en la pandemia de COVID-19.
