Clinical and Experimental Biomechanical Studies Regarding Innovative Implants in Traumatology

Fracture treatment has experienced a fascinating evolution in the last years. The aim of this chapter is to reveal some clinical and biomechanical studies regarding innovative implants. After a short introduction (1), we intend to present our results regarding (2) dynamic condylar screw versus condylar blade plate in complex supracondylar femoral fractures; (3) biomechanical analysis of four types of implants in humeral fractures; (4) clinical and experimental studies for optimal stabilization of trochanteric fractures: the gliding nail; (5) intramedullary XS nail for pilon and ankle fractures: design, biomechanics, and clinical results; (6) the XS nail for the treatment of patella and olecranon fractures; and (7) plates with polyaxial stability for fractures of distal radius and proximal humerus. In conclusion, the authors highlight the advantages of these innovative implants in difficult trauma cases

CAREER OPPORTUNITIES FOR DENTAL STUDENTS THROUGH EUROPEAN PROJECTS

Aim of the study The aim of this study is to emphasize the important role of career counselling in choosing the right career path. The dental students have multiple choices in their future career; the most important thing is to have access at objective tools in order to identify the most suitable trajectory. Material and methods We applied a questionnaire among the dental students from Iasi, the 6th year of study, during a period of 7 years (2011-2017) in order to identify their choices for the future career. The statistical processing was made in SPSS 20.0 and we reported the descriptive and the analytical results. Results It will be structured as shown here. Conclusions The study has shown that targeted career counselling has an important and valuable role in establishing the correct professional trajectory according to the individual skills, competences and aspiration

THE PREVENTION OF MEDICAL EMERGENCY IN DENTAL PRACTICE

The diagnosis and management of medical emergencies represents a current issue for dental practitioners, considering the high prevalence of medical disorders, patients receiving polypharmacy as well as the preoperative fear and anxiety among patients receiving dental care. In-depth knowledge of the factors that regulate the chronically disease processes, and pharmacodynamics of drug action, complete medical history and physical examination, as well as stress reduction protocols are requested for effective prevention of medical emergencies in dental office

DENTAL ANTIBIOTIC PROPHYLAXIS IN TOTAL JOINT REPLACEMENT: AN UPDATED REVIEW OF GUIDELINES AND CLINICAL STUDIES

Aim of the study: This review evaluates the necessity and effectiveness of antibiotic prophylaxis in preventing prosthetic joint infections (PJI) following dental procedures in patients with joint implants.Material and methods: An extensive literature review was conducted, focusing on studies evaluating the link between dental care and PJI. Sources included PubMed and other databases, using terms such as dental care, joint prosthesis, and antibiotic prophylaxis. The review spanned papers from 2003 to 2023, with a focus on hip and knee joint replacements and dental procedure-related prophylaxis guidelines.Results: The review found that the prevalence of dental pathology in patients with total hip arthroplasty (THA) or total knee arthroplasty (TKA) varied significantly. Studies indicated no significant benefit of antibiotic prophylaxis in reducing PJI risk post-dental procedures. Furthermore, the incidence of PJI was not significantly different in patients receiving antibiotic prophylaxis compared to those who did not. It was observed that routine activities, such as chewing and brushing, contribute more to bacteremia and potential joint infection than dental procedures themselves.Conclusions: The evidence suggests that antibiotic prophylaxis for dental procedures in patients with joint prostheses is not universally beneficial and should not be routinely recommended. Emphasis on individual risk assessment, maintenance of good oral hygiene, and adherence to evidence-based guidelines is paramount. The study advocates for personalized approaches to PJI prevention, aligning with the goals of antibiotic stewardship and patient safety

Electrochemical and In Vitro Biological Evaluation of Bio-Active Coatings Deposited by Magnetron Sputtering onto Biocompatible Mg-0.8Ca Alloy

The use of resorbable magnesium alloys in the design of implants represents a new direction in the healthcare domain. Two main research avenues are currently explored for developing or improving metallic biomaterials: (i) increase of their corrosion resistance by designed compositional and structural modifications, and (ii) functionalization of their surfaces by coating with ceramic or polymeric layers. The main objective of this work was to comparatively assess bio-functional coatings (i.e., highly-crystallized hydroxyapatite and silica-rich glass) deposited by radio-frequency magnetron sputtering (RF-MS) on a biodegradable Mg-0.8Ca alloy (0.8 wt.% of Ca). After probing their morphology (by scanning electron microscopy) and structure (by Fourier transform infrared spectroscopy and grazing incidence X-ray diffraction), the corrosion resistance of the RF-MS coated Mg-0.8Ca substrates was electrochemically tested (in synthetic biological media with different degrees of biomimicry), and their cytocompatibility was assessed in osteoblast and fibroblast cell cultures. By collective assessment, the most promising performances, in terms of mass loss (~7% after 12 days), hydrogen release rate (~6 mL/cm2 after 12 days), electrochemical corrosion parameters and cytocompatibility, were obtained for the crystalline HA coating
