Does being involved by doctors satisfy patients' fundamental psychological needs? A study on a large European sample
The present work was aimed at investigating whether the patients’ involvement by their healthcare providers may satisfy patients’ fundamental psychological needs (i.e. self-esteem, belonging, control, meaningful existence), which in turn, can impact their psychological well-being. Based on the European Quality of Life Survey data, the sample included 10,427 European adults who, in the last 12 months, visited GP/family doctors and hospital/medical specialists. Among them, 51.3% declared to have a chronic disease. Results showed that the experience of being involved by GP/family doctors and hospital/medical specialists had a positive effect on psychological well-being and that this effect was…
Biological and physico-chemical properties of new root canal sealers
Background The purpose of the present study was to compare the biological and the physico-chemical properties of bioceramic-based root canal sealers, calcium hydroxide-based, MTA-based and epoxy resin-based root canal sealers. Material and methods Two bioceramic-based sealers, one calcium hydroxide-based sealer, one MTA-based sealer and two epoxy resin-based sealers were tested. Results EasySeal and MTA Fillapex showed severe citotoxic activity, AH Plus and SealapexTM moderate cytotoxicity, BioRoot™ RCS and TotalFill BC Sealer were both cytocompatible. Except for TotalFill BC Sealer, all root canal sealers caused inhibition zones when tested with E. faecalis. The highest inhibition zone was…
Comparative cytotoxicity evaluation of eight root canal sealers
Background The aim of the present study is to evaluate and compare the cytotoxic effects of eight root canal sealers (BioRoot RCS, TotalFill BC Sealer, MTA Fillapex, Sealapex, AH Plus, EasySeal, Pulp Canal Sealer, N2) on immortalized human gingival fibroblasts over a period of 24, 48 and 72 hours. Material and Methods Immortalized human gingival fibroblast-1 HGF-1 (ATCC CRL-2014) were incubated. Root canal sealers were then placed into sterile, cylindrical Teflon moulds. The extraction was made eluting the sealers in cell culture medium. Cells (1 × 104) were seeded in each well of a 96-well plate and incubated for 24 h at 37°C. Cultures were then exposed to 100 μL of the extracts medium. Th…
