Floating License Management - Automation Using Web Technologies

This paper examines the use of distributed computing based on web services with application to floating license management. The main goal is to automate the processes pertaining to the management activities and ensure at the same time that the security and flexibility requirements are met. We present the challenges posed by these requirements, propose a design and some implementation aspects using the latest .NET development platform

HOLISTIC APROACH IN TMJ CLINICAL EXAMINATION

The TMJ exam represents a main stage in clinical examination of each patient, especially in temporomandibular desorder. Usually the clinical examination in dentistry is concentrated in oral aria, TMJ is examed just when the patients acuse simptoms. In a few minutes we can diagnose completely and corectly all problems of oro-facial system following a standard protocol

Computer Application for the Evaluation of the Dento-Somato-Facial Aesthetic Balance

DSF (Dento-Stomato-Facial) Aesthetic Software is an application that focuses on aesthetic evaluation based on the following inter-related directions: body aesthetics, dental-facial aesthetics, dento-gingival aesthetics, dental-dental aesthetic and dental aesthetics. The application employs different images processing technics and the modern .net development platform. The application contributes to a better identification and use of the dento-facial and somatic aesthetic evaluation criteria. The software can display all the determined measurements or only those which diverge from the normal ones. The final reports can be presented either superimposed on the patient picture showing the deviated segments or on a standard image from the software library which can be also access at any time though the help function. Although the application can reveal the deviated values from the normal ones, thus pointing towards a diagnostic, the final interpretation however belongs to the dentist. The practitioner will establish the final diagnostic by correlating the data obtained from the computer application with that from clinical and paraclinical evaluation which is necessary for a complete and complex approach of the case

STATISTICAL STUDY REGARDING THE PUTTY-WASH TECHNIQUE IMPRESSIONS RECORDED BY STUDENTS

Introduction The impression record is an issue with many problematic aspects that can be manageable with correct understanding of circumstances involved. The putty-wash technique is the most frequent dental impression used in fixed prosthodontics. Aim of the study The purpose of the study is to evaluate the most common mistakes that are encountered by 4th year dental medicine students of U.M.Ph Iaúi during the impression record by putty-wash technique. Material and method 39 students of the 4th English section recorded on each other 78 maxillary and mandibular impressions, using the wash-technique, and then casted it. The materials used were “Zetaplus” and “Oranwash” condensation silicones (Zhermach, Italy). After the impressions and casts evaluation, the records were ranked in 3 classes: Class 1 (excellent), Class 2 (acceptable) and Class 3 (poor). The evaluation criteria involve aspects regarding different stages of the record: chosen tray, material manipulation, record, impression examination and casts examination. Results Considering that the records were performed on patients without prepared teeth, the study is focusing on the general errors, which impairs on the quality of the impressions and casts, leading to indirect restoration faults. Conclusions This study was a very good instrument in exposing the possible mistakes during impression record, making the students more aware of the problems that can arise, even in non-problematic, non-stressful clinical conditions

THE VALIDATION OF AN ACRYLIC RESIN FOR THE COMPLETION OF BIOMECHANICAL STUDIES ON A MANDIBULAR MODEL

Aim of the study The aim of this study was to validate the use of a self-curing acrylic resin for the completion of a mandibular model for in vitro studies. Material and methods 25 test specimens were made of acrylic resin (Duracryl Plus, Spofa Dental). The samples were divided in 5 groups, based on monomer to polymer ratio. The determination of the elasticity modulus and of the Poisson’s ratio for the studied samples was performed using the electrical resistive tensometry method. The samples were submitted to traction testing on a universal testing machine. Results The elastic characteristics of the material varied significantly depending on the components proportion. The evaluated ratio is 3 parts of powder to 1.5 parts of liquid. This combination presented elastic characteristics similar to those of the spongy bone from the anterior region of the mandible, as well as an average viscosity that contributes to pouring in complex forms, to a proper work time and to a low curing contraction. Conclusions Based on the obtained results, we can consider the use of self-curing acrylic resin, in a ratio of 3:1.5, as being justified for creating a mandibular model to be used in biomechanical tests. Keywords: acrylic resin, strain gauges, mandibular model, modulus of elasticity, Poisson’s rati

Exploring the Role of Interleukin-6 Receptor Inhibitor Tocilizumab in Patients with Active Rheumatoid Arthritis and Periodontal Disease

Background: The aim of our study was to explore the influence of weekly subcutaneous administration of interleukin-6 (IL-6) receptor inhibitor tocilizumab (TCZ) on periodontal status in a local longitudinal study of patients with rheumatoid arthritis (RA) and periodontal disease (PD). Methods: We performed a 6-month prospective study in 51 patients with chronic periodontitis and moderate-to-severe RA starting TCZ in accordance with local recommendations. Extensive rheumatologic (clinical activity, inflammatory, serological biomarkers) and periodontal (visible plaque index, gingival index, bleeding on probing, probing pocket depth, clinical attachment loss) assessments were done. Changes in RA activity and periodontal status were reassessed after 3 and 6 months. Results: We demonstrated significant correlations between periodontal status, disease activity, and serologic biomarkers (p < 0.05). Tocilizumab significantly improved the gingival index scores and decreased the number of sites with bleeding on probing after only 3 months (p < 0.05), while the probing pocket depth significantly decreased after 6 months; overall, clinical attachment loss presented only slight changes without any statistical significance as well as teeth count and plaque levels (p > 0.05). Conclusion: IL-6 inhibition is able to improve periodontal outcomes in patients with RA and concomitant PD, which is essentially related to a dramatic decrease in serum inflammatory mediators
