DIFFERENT TECHNIQUES FOR DENTAL IMPLANTS SITE PREPARATION: A CONTROLLED CLINICAL TRIAL
No full textDental implants should be considered a highly predictable long-term and evidence-based treatment option for single, partial, and complete edentulism of the jaws, as indicated by numerous scientific articles. The primary aim of the present study was to determine whether the application of one implant site preparation protocol (“Step drilling sequence”) could lead to a significantly lower marginal bone resorption as compared to another protocol (“Straight drilling sequence”) at 1-year follow-up. The secondary aims were to evaluate if the tested protocol (Step drilling sequence) could modify the clinical and/or patient-centered variables We included and treated 60 subjects, for a total of 86 implants. We found no evidence of a difference in bone resorption, which increased significantly over time, between the two groups. Regarding the secondary outcomes, no statistically significant difference was observed between the test group and the control group, neither for peri-implant probing depth (PD), for bleeding index (BI), plaque index (PI) nor for the quality of life. In conclusion, from a purely biological perspective, there is currently no evidence in favor of using a step drill over a traditional straight drill. However, from a clinical standpoint, the use of step drills is advantageous for operator convenience compared to traditional drills
The effect of the use of proton pump inhibitors, serotonin uptake inhibitors, antihypertensive, and anti‐inflammatory drugs on clinical outcomes of functional dental implants: A retrospective study
No full textOBJECTIVE: The present retrospective study investigated the effect of chronic intake of proton pump inhibitors, selective serotonin uptake inhibitors, anti‐inflammatory, and antihypertensive drugs on the survival of dental implants and on the occurrence of peri‐implantitis. MATERIALS AND METHODS: Survival analyses for implant failure and peri‐implantitis were performed patient level for each drug subcategory and for risk factors. The HR for each drug was calculated with adjusted models as compared with a control group made of subjects not assuming the specific drug. Multilevel logistic regression was used to explore the influence of implant‐level and patient‐level variables on the outcomes. RESULTS: A total of 270 subjects receiving 1118 dental implants were included, with a mean follow‐up time of 5.19 ± 4.22 years. After 10 years, the survival rate was 86.9% (patient level), and according to survival analysis, 61.3% of subjects were free from peri‐implantitis. The use of anti‐inflammatory medicines produced a significant effect (p = .04) on peri‐implantitis as compared to subjects not using the drug, with a 2.7‐year drop in the mean survival time. The HR was slightly above the level of significance in a semiadjusted model (p = .058). The multilevel analysis found a significant effect on the entire sample and not when considering only subjects with implants with more than 1‐year follow‐up. CONCLUSIONS: We found a possible relationship between anti‐inflammatory drug use and the occurrence of peri‐implantitis in the examined cohort of patients, and no correlation for the other drugs

No full textThe fascinating study of biological evolution has not yet provided answers about what separates living from inanimate matter. Although evolution is evidently part of a programme involving self-organization, it is unclear whether this programme is part of an established plan. Time plays a complex fundamental role, but no precise definition of time has yet been proposed. However, connections between modern theories, especially Prigogine's irreversibility and Tiezzi's ecodynamics, provide a macroscopic view of the world that enables comparison of the different levels that compose it. © 2012 WIT Press
Los apuntes autobiográficos de un morisco expulsado: algunas reflexiones sobre el prólogo del Ms. S2 de la Colección Gayangos de la Biblioteca de la Real Academia de la Historia de Madrid
No full textThis paper aims to study some details, concerning style and themes, that the anonymous Moorish author determined to provide in the prologue of the manuscript S2 of the Gayangos Collection of the Library of the Real Academia de la Historia in Madrid [ff. 2r-16v]. Particularly, the attention is focused on the autobiographical notes inserted in the prologue, important narrative sequences in which the author tells the tough conditions suffered as a crypto-Muslim in Seventeenth-century Spain.El presente trabajo procura realizar una observación sobre algunos detalles estilísticos y temáticos que el autor morisco anónimo determina brindar en la sección del prólogo del manuscrito S2 perteneciente a la Colección Gayangos de la Biblioteca de la Real Academia de la Historia de Madrid [ff. 2r-16v]. De manera particular, la atención se focaliza en los apuntes autobiográficos intercalados en el mismo prefacio, importantes secuencias narrativas en las que el autor relata la durísima condición que sufrió como criptomusulmán en la España del siglo XVII
Per un teatro che crede nella storia. Pier Paolo Pasolini nell'opera di Heiner Müller
No full textAim of this essay is to analyse the role of Pier Paolo Pasolini in the work and poetics of the GDR-author Heiner Müller. After an analysis of the reception of Pasolini’s works and persona in Germany and in the specific context of the GDR, the current work focuses on the influence of PPP in Müller’s approach to language, identity and history
The cobordism ring: the perspective of characteristic classes
No full textThis written work, by Benedetta Andina, discusses ``The cobordism ring: the prospective of characteristic classes''. After providing sufficient preliminaries to make this thesis accessible to any graduate student, it clearly highlights how both the oriented and unoriented cobordism rings can be studied using characteristic classes, which are usually easily computable. To demonstrate this relationship in the unoriented case (as presented by Pontrjagin and Thom), the author unveils an explicit structure of the unoriented cobordism ring. This structure provides a clear classification of smooth closed manifolds
The influence of implant position and of prosthetic characteristics on the occurrence of peri-implantitis: a retrospective study on periapical radiographs.
No full textOBJECTIVE: The present retrospective study aimed to investigate the influence of malposition on the occurrence of peri-implantitis. MATERIALS AND METHODS: The study included clinical records of systemically healthy patients with single and partial implant-supported rehabilitations and at least 1-year post-loading follow-up. The parameters collected included implant-related factors, patient-related factors, site-related factors, and prosthesis-related factors. The radiographic measurements were taken by using a dedicated software and the diagnosis of peri-implantitis was made based on all the available clinical and radiographic data. Descriptive statistics were provided for all variables. Following an exploratory approach, an implant-level analysis of factors influencing the occurrence of peri-implantitis was done through a multilevel multivariate logistic regression (mixed). RESULTS: A total of 180 implants belonging to 90 subjects were randomly selected. Malposition showed no statistically significant association with the occurrence of peri-implantitis. According to the multi-level analysis, the parameters that were significantly associated with peri-implantitis included presence / history of periodontitis (OR = 5.945, 95% CI: 1.093 - 32.334, P = 0.039) and presence of an emergence profile angle ≥ 45° (OR = 9.094, 95% CI: 2.017 - 40.995, P = 0.005). CONCLUSIONS: Implant malposition, as defined following Buser's criteria (2004), did not influence the occurrence of peri-implantitis in the selected cohort. Conversely, history of periodontitis and presence of a prosthetic emergence profile with an angle ≥ 45° were correlated to an increased risk of peri-implantitis
Book review: Lobbying in the European Union: interest groups, lobbying coalitions, and policy change
No full text"Lobbying in the European Union: Interest Groups, Lobbying Coalitions, and Policy Change." Heike Klüver. Oxford University Press. February 2013. --- Why can some interest groups influence policy-making while others cannot? Even though this question is central to the study of politics, we know little about the factors explaining interest group influence. This book aims to shed light on the impact of interest groups on European policy-making, with author Heike Klüver developing a comprehensive theoretical model for understanding lobbying success.
