BSDR Conference in Glasgow

As previously announced, the BSDR Conference is taking place in Glasgow. The Santini Miletic Research Group presented a study entitled "The ratio of carbon-carbon double bonds in different BisGMA/HEMA mixtures". Click on the image.
Prior to the poster session, I attended the Ceramics session chaired by professor Richard Van Noort. Several very interesting studies were presented regarding CAD-CAM ceramic strength, ceramic reinforcements, fluoride-containing bioactive glasses, leucite glass-ceramic crystallisation, coating materials for zirconia ceramics and wear quantification using profilometry. It was quite impressive to see the very high standard of research carried out at various universities in the UK.

Sponsored by 3M ESPE, the Dental Materials Group Symposium was held during the afternoon session. After the opening remarks by Dr Garry Fleming and Professor R. Van Noort, lectures were given by Dr Rainer Guggenberger (The chemistry of new resin systems), Professor David Watts (The measurement of shrinkage and contraction stress), Professor Tim Watson (The quality of adhesion) and Professor Trevor Burke (Early thoughts of clinical experience using the novel silorane-based composite material). The lectures increased our knowledge on various aspects of resin-based composites and the silorane-based material in particular. The 'non-shrink' resin composites are still not a reality but dental technology has made substantial improvements towards this goal.

Publishing papers: initial observations as an author and a referee

Three basic rules for referees

I've published 9 papers in peer-reviewed dental journals in the last 2 years and have refereed half a dozen papers regarding dental materials, adhesives, resin-based composites, adhesive cements, adhesion, marginal adaptation... Since there's no 'school' or 'course' for referees that I'm aware of, I've started developing my own style. Judging from other people's reviews of my papers, this seems to be the case with most referees out there. I know that the following are very basic rules, but sometimes, even such basic rules are not followed.

Though editors put a lot of effort in finding the right referees for a particular paper, it's possible that a paper ends up in wrong hands, with someone whose field of expertise has almost nothing to do with the subject of the paper. I've noticed very 'interesting' remarks regarding one of my papers indicating that the referee wasn't an expert in the field he/she was referring to. Obviuosly, nowadays a lot of studies are multidisciplinary and this makes it even more difficult for editors to find competent referees. A potential referee may be an expert regarding only a part of a particular study. It's only fair to comment on that part and indicate this to the editor so that a competent person is invited to comment on the other part(s).

So, rule No.1: accept an invitation to review a paper only if you're an expert in the field or at least a part of it and indicate this to the editor. Decline review if the subject of the paper is not your area of expertise.

Another thing I've noticed with people refereeing my papers is that this process sometimes takes ages. Though some journals have taken steps to ensure speedy review within 3-6 weeks, with some journals this may take even more than 6 months. This is simply unacceptable. Being in a referee's position myself, I've realised that even 3 weeks is more than enough to complete a review. Of course, I'm well aware of the fact that referees are very busy and have many, many other things to do. But so are the authors and referees should respect that. It's unfair to keep someone's paper 'under review' for more than a month.

So, rule No.2: accept an invitation to review a paper only if you can complete the review in less than 3 weeks.

Also, I've noticed that there are people who just don't care about the paper they're reviewing. They tend to write and overall impression of the paper without going into specific details. This is not helpful even if the paper is good and especially if it needs to be improved. It's almost like they just skimmed through the paper. On the other hand, there are people who write extensive reviews and I find these extremely helpful.

So, rule No.3: be fully committed to reviewing a paper. Go into minute details when writing a review.

Santini Miletic Research Group: new website


The new website of the Santini Miletic Research Group is up and running. Please visit us at http://www.santinimiletic.com/




In addition to the short CVs of group members, there is a list of selected papers published recently in international peer-reviewed journals. There is also information on research facilities available to the Group and various methods of knowledge transfer.

Up-coming event

British Society for Dental Research Conference, Glasgow, Sept 1-4, 2009.

The keynote speakers are Professor Angus Walls, Professor of Restorative Dentistry, School of Dental Sciences, Newcastle University and Professor Iain McInnes, Professor of Experimental Medicine, Division of Immunology, Infection and Inflammation, Faculty of Medicine, University of Glasgow.

Professor Angus Walls' lecture - "The ageing population, opportunity or threat?"
Professor McInnes' lecture - "Immune complexity to novel therapy - promises for a new decade?"

The following symposia are scheduled:

- Non-shrink resin composites: Dream or reality?
Aim: This symposium examine current developments of resin-based restoratives, indicating the advantages and disadvantages of resin types routinely and review the most recent advancements in resin technology.
Speakers:
Professor Ric van Noort, University of Sheffield: Opening remarks
Dr Rainer Guggenberger, 3M/ESPE: The chemistry of new resin systems
Dr N Silikas University of Manchester: Measurement of shrinkage and contraction stress
Professor Tim Watson Kings College London: Quality of adhesion
Professor Trevor Burke University of Birmingham: Early thoughts of clinical experience

- Novel biomaterials - can the microenvironment be improved ?

- Childsmile a Scottish oral health programme for Scottish children: collaborations and innovative evaluations

- The oral microbiota and the link with systemic disease

A total of 228 studies will be presented at the conference and the complete programme can be downloaded from HERE.

The Santini Miletic Research Group will present a study entitled "The ratio of carbon-carbon double bonds in different BisGMA/HEMA mixtures". The poster will be uploaded to this blog after the conference.

One-step self-etch adhesive, Adhese One F

A new one-step self-etch adhesive, Adhese One F, manufactured by Ivoclar Vivadent has been sent to the Santini Miletic Research Group for scientific evaluation. The adhesive is based on previously developed Adhese One with the inclusion of potassium fluoride which is reported to act as a fluoride releasing agent. The manufacturer's internal data state that there is a cumulative fluoride release over a 6 day period.

Micro-Raman spectroscopic studies will be conducted to evaluate the ratio of carbon-carbon double bonds (RDB) of Adhese One F under different curing conditions. Furthermore, the adhesive-dentine interface will be characterised in terms of dentine demineralisation and adhesive penetration and the RDB across this interface.

A previous study has shown significantly lower RDB values for Adhese One in both the adhesive and the hybrid layer compared to Excite (etch-and-rinse) and Adhese (2-step self-etch). In another study, Adhese One produced a thinner hybrid layer compared to G Bond (1-step self-etch), Filtek Silorane adhesive system (2-step self-etch) and Excite
