Internationally, evidence-based practice (EBP) is recognised as a foundational element of healthcare professional education. Achieving competency in this area is a complex undertaking that is reflected in disparities between ‘best EBP’ and actual clinical care. The effective development and implementation of professional education to facilitate EBP remains a major and immediate challenge. To ascertain nuanced perspectives on the provision of EBP education internationally, interviews were conducted with five EBP education experts from the UK, Canada, Australia and New Zealand. Definitive advice was provided in relation to (1) EBP curriculum considerations, (2) teaching EBP and (3) stakeholder engagement in EBP education. While a considerable amount of EBP activity throughout health profession education is apparent, effectively embedding EBP throughout curricula requires further development, with a ‘real-world’ pragmatic approach that engenders dialogue and engagement with all stakeholders required.

The effect of pre-heating resin composite on pre-cured viscosity and post-cured surface hardness was evaluated. Groups of uncured specimens were heated to 60 degrees C and compared with control groups (24 degrees C) with respect to viscosity and surface hardness. Mean (SD) viscosities of the pre-heated specimens (n = 15) were in the range of 285 (13)-377 (11) (Pa) compared with 642 (35)-800 (23) (Pa) at ambient temperature. There was a statistically significant difference between the two groups (P < 0.001). Mean (SD) Vickers microhardness (VHN) of the pre-heated group (n = 15) was 68.6 (2.3) for the top surface and 68.7 (1.8) for the bottom surface measured at 24 h post curing (specimen thickness = 1.5 mm). The corresponding values for the room temperature group were 60.6 (1.4) and 59.0 (3.5). There was a statistically significant difference between corresponding measurements taken at the top and bottom for the pre-heated and room temperature groups (P < 0.001). There was no significant difference between top and bottom measurements within each group. Pre-heating resin composite reduces its pre-cured viscosity and enhances its subsequent surface hardness. These effects may translate as easier placement together with an increased degree of polymerization and depth-of-cure.

The quality of root canal fillings placed in single-rooted teeth by undergraduate dental students at the University Dental School and Hospital, Cork was acceptable (63% of root fillings placed in single rooted teeth were graded as 'adequate'). The probable reasons for this are multi-factorial, but may be linked to the amount of pre-clinical and clinical teaching in endodontics at the University Dental School and Hospital, Cork. It should be remembered that factors other than radiographic quality/evidence must be considered when determining the outcome of root canal therapy.

Final year students at Cardiff and Cork were most confident in simpler procedures and procedures in which they had had most clinical experience. They were least confident in more complex procedures and procedures in which they had the least clinical experience. Increased clinical time in complex procedures may help in increasing final year students' confidence in those areas.

Whilst dental students believe that rubber dam is relevant to clinical dentistry, there are negative perceptions associated with its use amongst dental students. More than half of those questioned predicted their use of rubber dam would decrease once in independent practice. Greater emphasis should be placed on the advantages of using rubber dam in clinical dentistry whilst at dental school.
