Digital Twins for Smart Cities and Villages
No full textDigital Twins for Smart Cities and Villages provides a holistic view of digital twin technology and how it can be deployed to develop smart cities and smart villages. Smart manufacturing, smart healthcare, smart education, smart agriculture, smart rural solutions, and related methodologies using digital twins are discussed, including challenges in deployment, their solutions and future roadmaps. This knowledge, enriched by a variety of case studies presented in the book, may empower readers with new capabilities for new research as well as new tasks and strategies for practical implementation and real-world problem solving. The book is thoughtfully structured, starting from the background of digital twin concepts and basic know-how to serve the needs of those new to the subject. It continues with implementation to facilitate and improve management in several urban contexts, infrastructures, and more. Global case study assessments further provide a deep characterization of the state-of-the-art in digital twin in urban and rural contexts

Comparing Gutta Percha Backfill Leakage Over Multiple Heating Cycles
Get PDFIntroduction: Warm vertical compaction of gutta-percha is a commonly used obturation technique due to the material’s thermoplastic properties. However, gutta-percha in backfill systems is often heated, cooled, and reheated multiple times before use, potentially altering its physical properties. This study investigated whether repeated heat cycling affects the sealing ability of gutta-percha, as measured by coronal dye leakage. Methods: Forty extracted single-rooted human teeth were cleaned, shaped, and randomly divided into four groups (n = 10) based on the number of heating cycles the gutta-percha underwent prior to obturation: Group A (1 cycle), Group B (3 cycles), Group C (5 cycles), and Group D (7 cycles). All teeth were obturated using the B&L Beta Mini backfill system set to 200°C. After obturation, roots were sealed with nail polish (excluding the orifice), submerged in India ink for 7 days, then cleared using a standard decalcification and dehydration protocol. Dye penetration was measured from the orifice to the deepest apical extent using ImageJ. Statistical analysis was performed using two-tailed Student’s t-tests (P \u3c 0.05). Results: Group A showed the least dye leakage (2.29 ± 1.07 mm). Leakage increased significantly in Groups B (4.1 ± 1.82 mm), C (5.62 ± 1.91 mm), and D (3.88 ± 1.27 mm) compared to Group A (P \u3c 0.05). No significant differences were observed among Groups B, C, and D (P \u3e 0.05). Conclusion: Repeated heating of gutta-percha was associated with increased coronal dye leakage. Clinicians should use caution when reusing gutta-percha subjected to multiple heat cycles to avoid compromising obturation quality
Persistent Opioid Use Following Major Orthopedic Surgery
No full textPurpose of Review: This narrative review addresses the growing public health concern of persistent opioid use following major orthopedic surgery. It aims to identify and analyze the critical factors that contribute to the transition from acute to persistent opioid consumption in this context. Recent Findings: Patient-related characteristics, including pre-existing conditions and prior substance use, are critical predictors of prolonged opioid use. Additionally, surgery-related factors such as the type and duration of procedures complicate postoperative pain management. The prevalence of persistent opioid use after surgery remains high despite the emergence of effective Enhanced Recovery After Surgery protocols and patient education initiatives. Multimodal analgesia is highlighted as a vital strategy for reducing the risk of long-term opioid dependency. Summary: Persistent opioid use after orthopedic surgery poses significant challenges, including increased risks of physical and mental health complications, the development of opioid use disorder, and a substantial economic burden on healthcare systems. Targeted interventions and continuous research are essential to mitigate these risks, reduce long-term opioid dependency, and improve overall patient outcomes
