Mercury Monohalides as Ligands in Transition Metal Complexes.

The main categories of transition metal-mercury heterometallic compounds are briefly summarized. The attention is focused on complexes and clusters where the {Hg-Y} fragment, where Y represents a halide atom, interacts with transition metals. Most of the structurally characterized derivatives are organometallic compounds where the transition metals belong to the Groups 6, 8, 9 and 10.

Dentin hypersensitivity and quality of life in patients with chronic systemic disease.

Objectives: To assess the potential impact of dentin hypersensitivity on the quality of life in people with chronic systemic diseases.

Methods: We included 252 volunteers, 18 years or older, with ≥ 6 teeth, and under outpatient medical follow-up for systemic chronic diseases. Short Form Health Survey 36 (SF-36) was used to assess quality of life (QoL); Oral Health Impact Profile-14 (OHIP-14) and Dentine Hypersensitivity Experience Questionnaire (DHEQ-15) were used for oral health-related quality of life (OHRQoL).

Comparative clinical evaluation of the stability of implants using double acid etching treatment with and without the addition of fluoride solution: A randomized clinical trial.

Background: Osseointegration depends on primary stability, and further, implant surface modifications may improve secondary stability. This randomized clinical trial evaluates whether adding a fluoride solution enhances the implant stability.

Materials And Methods: Stability of dental implants with two different types of surface treatments was compared utilizing resonance frequency analysis (RFA).

Atomically precise rhodium-indium carbonyl nanoclusters: synthesis, characterization, crystal structure and electron-sponge features.

In this paper we present the investigation of the reactivity of [Rh(CO)] with InCl, with the aim of expanding the more general study that allowed us to obtain, among other species, the icosahedral [RhE(CO)] ( = 4 when E = Ge or Sn; = 3 when E = Sb or Bi) family of clusters. Indeed, the study resulted in the isolation and characterization of the analogous In-centred icosahedral [RhIn(CO)] nanocluster (1), which is isoelectronic and isostructural with the [RhE(CO)] congeners. During the course of the reaction two more new species, namely the octahedral [Rh(CO)InCl] (2) and the dimeric [{Rh(CO)InCl}] (3) have also been identified.

Exploring the relationship between anxiety, patient characteristics and pain outcomes in oral surgery under local anesthesia: The measurement problem.

Background: Anxiety during oral surgery can impact patient homeostasis, increase the difficulty of the procedure and create additional stress for the surgeon. Furthermore, it has been associated with more intense and prolonged pain during and after dental treatment.

Objectives: The aim of the study is to evaluate the relationship between anxiety, patient characteristics and pain outcomes in oral surgery, as well as to verify the impact of anxiety on patient's perception of pain during and after oral surgery.
