Effect of Toothpaste on the Surface Roughness of the Resin-Contained CAD/CAM Dental Materials: A Systematic Review
Background: The purpose of this review is to describe the possible effect of toothbrushing on surface roughness of resin-contained CAD/CAM materials. Methods: Systematic literature search for articles published in peer-reviewed journals between January 2000 and February 2020 has been conducted, which evaluated the effect of brushing on surface roughness of resin-contained CAD/CAM dental materials. The research was conducted in Scopus, PubMed/Medline, Web of Science, Embase, and Science Direct using a combination of the following MeSH/Emtree terms: “brushing”, “resin-based”, “dental”, “CAD/CAM”, and “surface roughness”. Results: A total of 249 articles were found in the search during initial screening. Fifty-five articles were selected for the full-text evaluation after the steps of reading of abstract/title and remotion of duplicate. Only six articles fulfilled the inclusion criteria. The Cohen’s Kappa agreement test showed an index of 0.91 for full-text. Discussion: Four of five selected articles identified an increase of surface roughness on resin-contained CAD/CAM materials after toothbrushing. Although all the articles examined used different toothpastes with no homogeneous relative dentine abrasivity (RDA) and cycles of brushing, the findings are about the same. The possible reason is attributable to the compositions of the resin-contained CAD/CAM materials. Conclusions: The surface roughness of most resin-contained CAD/CAM materials was affected by artificial toothbrushing. Correct knowledge of the composition of the dental material and toothpastes is fundamental to avoid an increase of surface roughness on prosthetic rehabilitation

Hospital Organization and Importance of an Interventional Radiology Inpatient Admitting Service:Italian Single-Center 3-year Experience
In June 2005 a Complex Operating Unit of
Interventional Radiology (COUIR), consisting of an outpatient
visit service, an inpatient admitting service with
four beds, and a day-hospital service with four beds was
installed at our department. Between June 2005 and May
2008, 1772 and 861 well-screened elective patients were
admitted to the inpatient ward of the COUIR and to the
Internal Medicine Unit (IMU) or Surgery Unit (SU) of our
hospital, respectively, and treated with IR procedures. For
elective patients admitted to the COUIR’s inpatient ward,
hospital stays were significantly shorter and differences
between reimbursements and costs were significantly
higher for almost all IR procedures compared to those for
patients admitted to the IMU and SU (Student’s t-test for
unpaired data, p\0.05). The results of the 3-year activity
show that the activation of a COUIR with an inpatient
admitting service, and the better organization of the patient
pathway that came with it, evidenced more efficient use of
resources, with the possibility for the hospital to save
money and obtain positive margins (differences between
reimbursements and costs). During 3 years of activity, the
inpatient admitting service of our COUIR yielded a positive
difference between reimbursements and effective costs
of €1,009,095.35. The creation of an inpatient IR service
and the admission of well-screened elective patients
allowed short hospitalization times, reduction of waiting
lists, and a positive economic outcome.

Magnetization reversal signatures in the magnetoresistance of magnetic multilayers
The simultaneous determination of magnetoresistance and vectorial-resolved magnetization hysteresis curves in a spin valve structure reveals distinct magnetoresistive features for different magnetic field orientations, which are directly related to the magnetization reversal processes. Measurements performed in the whole angular range demonstrate that the magnetoresistive response originates from the intrinsic anisotropic angular dependence of the magnetization orientation between the two ferromagnetic layers. This also provides direct proof that the spin-dependent scattering in the bulk of the magnetic layers is at the origin of the magnetoresistive signal
