Using Co-Design to Develop a Collective Leadership Intervention for Healthcare Teams to Improve Safety Culture.

While co-design methods are becoming more popular in healthcare; there is a gap within the peer-reviewed literature on to do co-design in practice. This paper addresses this gap by delineating the approach taken in the co-design of a collective leadership intervention to improve healthcare team performance and patient safety culture. Over the course of six workshops healthcare staff, patient representatives and advocates, and health systems researchers collaboratively co-designed the intervention.

The Effect of Irradiation Distance on Light Transmittance and Vickers Hardness Ratio of Two Bulk-fill Resin-based Composites.

The aims of this study were to assess the light energy transmission and Vickers hardness (VH) ratio of two bulk-fill resin-based composites (RBCs) (Tetric EvoCeram and Filtek) cured at different distances between the light curing unit's (LCU) tip and the surface of the restoration (T-S) using either a Bluephase G2, Bluephase® 'turbo tip' or Bluephase Style LCU. Samples were cured from the top at T-S distances of 2mm, 6mm and 10mm for 20 seconds. A MARC-Resin-Calibrator™ recorded the transmitted irradiance reaching the bottom of the sample, in real time.

Hereditary dentine disorders: dentinogenesis imperfecta and dentine dysplasia.

The hereditary dentine disorders, dentinogenesis imperfecta (DGI) and dentine dysplasia (DD), comprise a group of autosomal dominant genetic conditions characterised by abnormal dentine structure affecting either the primary or both the primary and secondary dentitions. DGI is reported to have an incidence of 1 in 6,000 to 1 in 8,000, whereas that of DD type 1 is 1 in 100,000. Clinically, the teeth are discoloured and show structural defects such as bulbous crowns and small pulp chambers radiographically.
