Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used for pain and inflammation control in dental practice, yet their gastrointestinal risks remain frequently underestimated, particularly in older adults. This report introduces two 80-year-old men with odontogenic infection, who had serious upper gastrointestinal bleeding (UGIB) as a result of abusing NSAIDs before hospitalization. Laboratory test and upper gastrointestinal endoscopy confirmed the UGIB in patients. They received fluid resuscitation and blood transfusion. Hemostasis was achieved through epinephrine injection and cauterization. Patients was kept nir per os, and continuous use of intravenous proton pump inhibitors (PPIs) was followed. These cases highlight the need for appropriate risk assessment and preventive strategies, such as concomitant use of PPIs or use of alternative analgesics, especially in older patients.

Ischemic necrosis of the tongue is rare condition due to its rich vascular supply. No cases have been reported in Korea to date. A 55-year-old male with a history of dyslipidemia and fatty liver presented with abdominal pain and vomiting. Despite fluid resuscitation, he developed severe hypotension, requiring vasopressor support and mechanical ventilation. During his intensive care unit stay, the patient exhibited signs of disseminated intravascular coagulation, with progressive skin necrosis and thrombocytopenia. Upon extubation, oral examination revealed widespread mucosal discoloration and blood clots, and ischemic necrosis on dorsal surface of the tongue was confirmed. This case highlights the potential risk of tongue ischemia as a rare but serious complication of multifactorial cause including prolonged vasopressor use and endotracheal intubation. Further studies are needed to better understand its pathophysiology and improve management strategies.

The vertical height of the alveolar bone and the amount of remaining bone are important factors in the long-term success of implants. If the remaining bone is insufficient, procedures such as vertical alveolar ridge augmentation, like guided bone regeneration, are necessary for ideal implant surgery. Among the non-resorbable membranes that can be used in these procedures, titanium mesh offers advantages such as maintaining space for bone grafting, protecting the underlying graft material, and allowing adjustment to match the defect site for desired shaping. However, fixation of titanium mesh, which is crucial in determining the overall success of the surgery, requires the use of multiple screws and may result in membrane exposure during the healing process. To overcome these problems, a recent development involves the use of fixture-supported titanium-mesh, which has demonstrated good results. This study suggests that vertical alveolar ridge augmentation using fixture-supported titanium mesh can resolve conventional problems and can be considered an effective and reasonable strategy for achieving ideal implants.

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.

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.

Vascular malformations in the oral cavity are congenital vascular anomalies with potential functional and aesthetic im-plication. Over the years, the demand for effective and minimally invasive treatments for oral vascular malformations has increased. This study presents a case series of six patients diagnosed with oral vascular malformations, who underwent sclerotherapy using sodium tetradecyl sulfate. Treatment showed satisfying results without any recurrence.

In oral and maxillofacial surgery, tracheostomy is an occasional procedure in patients with inflammatory diseases, neo-plastic diseases, and trauma. Subcutaneous emphysema is one of the complications of tracheostomy, and is consequence of air introduction or other gases into soft tissues. It is not a common complication, but it does occur occasionally. In 3 cases, Subcutaneous emphysema occurred after tracheostomy accompanied by oral and maxillofacial surgery. And it improved in 2, 3, and 13 days after the occurrence. The purpose of this study is to analyze the treatment and results of clinical cases of subcutaneous emphysema after tracheostomy in patients who underwent oral and maxillofacial surgery and use them as indicators of future treatment.
