Examining the Relationship Between Social Media Addiction, Fear of Missing Out, Loneliness, and Life Satisfaction Among Youth: A Cross-Sectional Study
(Serbian Psychologists, 2026) Işık, Nurten Arslan; Keleş, Dilsa Azizoğlu; Sandıkçı, İrem Nur; Kotyk, Taras; Okanlı, Ayşe
This cross-sectional study examines the relationships among social media addiction, fear of missing out (FoMO), loneliness, and life satisfaction among young adults. Data were collected from 700 participants aged 18-29 years via an online survey administered between May and June 2024. Validated scales were used to assess key variables: the Bergen Social Media Addiction Scale, the Fear of Missing Out Scale, the UCLA Loneliness Scale, and the Satisfaction with Life Scale. Structural Equation Modeling revealed that life satisfaction was positively associated with loneliness. Social media addiction was strongly associated with FoMO, while FoMO had an indirect negative effect on life satisfaction through social media addiction. These findings shed light on the underlying mechanisms between social media addiction, FoMO, loneliness, and life satisfaction. Such insights can provide significant implications for developing interventions (e.g., digital well-being programs) to help young adults manage their social media use more effectively. Promoting mindful and balanced social media engagement may contribute to enhancing life satisfaction and overall mental well-being.
A Comparative SWOT Analysis of Hospital Management Protocols for Radiation Accidents in Türkiye and Japan
(2025) Kolçak, Dilek
Background: The situation in which radiation emerges uncontrollably is referred to as a radiation accident. Radiation accidents constitute emergencies that can have severe impacts on public health. Therefore, it is of critical importance for hospitals providing healthcare services to be adequately prepared for such incidents. Materials and Methods: This study aims to compare the hospital management protocols for radiation accidents in T & uuml;rkiye and Japan using the strengths, weaknesses, opportunities, threats (SWOT) analysis method. As a country that has experienced a radiation accident, Japan's postincident developments are compared with T & uuml;rkiye's current situation. The study first examines the radiation safety regulations, healthcare policies, and hospital management strategies of both countries. While T & uuml;rkiye has established general protocols under the Hospital Disaster and Emergency Plan (HAP) and for Chemical, Biological, Radiological, and Nuclear (CBRN) incidents, Japan has enhanced its crisis management and emergency response systems following the 2011 Fukushima Nuclear Accident. Within the framework of the SWOT analysis, the strengths and weaknesses of both countries, potential threats, and opportunities for improvement are analyzed in detail. Results and Discussion: This study highlights how T & uuml;rkiye can benefit from Japan's crisis management experience to enhance its preparedness for radiation accidents. The analysis reveals that T & uuml;rkiye has significant shortcomings, particularly in training, drills, and hospital infrastructure. However, its investments in nuclear energy provide opportunities for development through international collaborations. On the other hand, although Japan possesses advanced radiation monitoring systems and extensive experience, it remains under constant threat due to its high concentration of nuclear power plants and exposure to natural disasters. Conclusion: To prevent radiation accidents, it is recommended to develop a hospital management model based on international standards. Additionally, effective intervention strategies should be formulated through the collaborative decision-making of hospital administrators, healthcare professionals, and policymakers to ensure a comprehensive response to radiation accidents.
Malocclusion as a Cause of Temporomandibular Joint Disorders
(2025) İşçi, Kemal Devrim
The jaw and skull are joined at the temporal mandibular joint (TMJ), a synovial joint. You can find these two joints directly in front of your ears. Each joint comprises the mandibular condyle, the temporal bone’s articular tubercle, and an articulating disk. Allowed motions include lateral, vertical, and horizontal movement, protrusion, and retrusion. The complex motions of chewing, speaking, and generating facial emotions are made possible by this joint and the muscles that link to it. The joint pain and dysfunction that affect the jaw joint are known as temporomandibular disorders (TMDs) or TMJ syndrome. Myalgias, myofascial pain, arthralgia, disk displacement disorders, degenerative joint disease, subluxation, and 11 other pain-related and intra-articular TMJ diseases have been found by an international group. © 2025 Springer Nature Switzerland AG.
Treatment of a Class II, Division 1 Malocclusion and Ectopic Canines with Invisalign Mandibular Advancement and the Bootstrap Technique
(2025) Taslan Ceylanoğlu, Sinem; Ceylanoğlu, Cenk; Alcan, Toros
In a growing patient, a Class II, division 1 malocclusion is often treated by inducing supplementary mandibular growth with functional appliances. As Toth and colleagues reported, the correction is achieved through a combination of normal growth and mandibular skeletal and dento alveolar changes. 1 The proportion of skeletal to dental effects is determined by the timing of treatment,2, 3 the mode of mandibular advancement,4, 5 and the type and rigidity of the appliance.3, 6-8 © 2025 JCO, Inc.
Effect of solvent use on dentin crack in retreatment
(2024) Zümrütel, Pelin; Haznedaroğlu, Faruk; Keleş, Ali; Basmacı, Gülsüm Kutlu
AIM or PURPOSE: The aim of this study was to evaluate the effect of solvent use on dentinal crack formation in during root canal retreatment with micro-CT. MATERIALS and METHOD: Root canal treatments were performed on the mesial roots of 20 mandibular molars. The teeth were divided in two groups: Group A: solvent and Group B: Non-solvent. During primary treatment, canal preparation was performed using Revo-S files. The root canals were filled using the lateral compaction technique and AH Plus sealer. During retreatment procedure, Protaper Retreatment Files were used in both groups. Guttasolv was used as solvent during retreatment in group A. Before and after the initial treatment and retreatment, the teeth were imaged using microCT. Meanwhile, the remaining root canal filling materials in the teeth were also examined. RESULTS: Crack formation was not observed in either group. Residual filling material remained in the root canal after the procedure in both groups and there was no statistical significant difference found in terms of residual matter between the regions according to the results of the measurements made separately in three regions as coronal, middle, and apical regions. CONCLUSION(S): In conclusion, within the limitations of this in vitro study, it could be said that Ni-Ti systems do not cause dentin defects if used with or without a solvent. Even if the retreatment was performed close to ideal, it was determined that residual filling material remained on the canal walls during retreatment.
