The present study evaluated, in vitro, the influence of an eugenol-based endodontic sealer (EndoFill) on the adhesion of intra-radicular posts cemented with a resin-based cement (Enforce) ou a zinc phosphate cement. Twenty-four single-rooted maxillary canines were divided into 2 groups (n=12) and obturated with either gutta-percha points plus EndoFill or gutta-percha points alone (no cement). I...

BACKGROUND AND PURPOSE Antibiotic-impregnated cement is used as a spacer or during re-implantation surgery for the treatment of infected total hip arthroplasties. The routine use of antibiotic-impregnated cement during primary or uninfected revision total hip arthroplasty remains controversial. With this meta-analysis of the published literature, we intended to assess efficacy and safety in the...

PURPOSE To investigate different techniques used by dentists when luting an implant-supported crown and to evaluate the application of cement quantitatively and qualitatively. MATERIALS AND METHODS Participants were given a bag containing cement sachet, mixing pad, spatula, a variety of application instruments, and a polycarbonate crown form. The participants were instructed with a standardiz...

Background: No scientific evidence exists regarding the amount of bone cement used and discarded in primarycemented Total knee arthroplasty (TKA). The aim of this study was to identify the exact amount of bone cement utilizedfor component fixation in primary TKA.Methods: In a prospective study carried out at five centers, 133 primary cemented TKAs were performed. One packof 40g Palacos bone cem...

BACKGROUND The cementation of fixed implant-supported dental restorations involves the risk of leaving excess cement in the mouth which can promote biofilm formation in the peri-implant sulcus. As a result, an inflammation may develop. PURPOSE The aim of the present study was to investigate the clinical effect of two different luting cements on the peri-implant tissue. MATERIALS AND METHODS...

We carry out a finite-size scaling analysis of the jamming transition in frictionless bidisperse soft core disks in two dimensions. We consider two different jamming protocols: (i) quench from random initial positions and (ii) quasistatic shearing. By considering the fraction of jammed states as a function of packing fraction for systems with different numbers of particles, we determine the spa...

The behavior of a single impurity in a one-dimensional Luttinger liquid is numerically investigated by means of the density matrix renormalization group. By analyzing the finite size scaling behavior of the low energy spectrum, we confirm the theoretical prediction of Kane and Fisher [Phys. Rev. Lett. 68, 1220 (1992)] both for attractive and repulsive interactions. Moreover, we calculate the ex...

The class of nilpotent groups of class c and prime exponent p> c with additional predicates Pc ⊆Pc−1 ⊆ . . . ⊆P1 for suitable subgroups has the amalgamation property. Hence the Fräıssé limit D of the finite groups of this class exists. 〈1〉⊆Pc(D)⊆ . . . ⊆P2(D)⊆P1(D)=D is the lower and the upper central series of D. In this extended language, D is ultrahomogeneous. The elementary theory of D allo...

It is known in thin-film deposition that the density of nucleated clusters N varies with the deposition rate F as a power law, N ∼ Fα. The exponent α is a function of the critical nucleus size i in a way that changes with the aggregation limiting process. We extend here the derivation of the analytical capture-zone distribution function Pβ(s) = aß ·sβ ·exp(-bβs2) of Pimpinelli and Einstein to g...
