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

Poll for dentists and dental therapists

What type of adhesive system do you use in your practice?

Please, select one or more answers from the poll in the sidebar.

Adhesive systems are classified according to the number of clinical application steps and adhesion strategy. This is one of the most widely accepted classifications in both clinical practice and scientific literature.

Feel free to leave a comment about your experience with any particular adhesive system.

In clinical practice, I'm using a two-step etch-and-rinse system. In PhD research, I've studied the degree of conversion and elution of unreacted monomers from a wide range of adhesive systems. Some of these results have been published in scientific dental journals and some are in press and will be published soon.

Though one-step (all-in-one) self-etch systems are currently marketed, results from many in vivo and in vitro studies suggest that these systems often have inferior properties compared to two-step self-etch and etch-and-rinse systems.

About me

My name is Vesna Miletic and I graduated in dentistry at University of Belgrade, School of Dentistry, 2000. This is the shortest version of my CV:

- Obtained MSc in 2005. Subject: Finite element analysis of stress distribution on a 3D tooth model.

- Since 2001, employed at Belgrade School of Dentistry as a clinical lecturer in the Department of Restorative Dentistry and Endodontics.

- Enrolled as a postgraduate student at the University of Edinburgh in 2007. Expected date of thesis submission - January 2010.

- Areas of study:
Micro-Raman spectroscopic analysis of dental adhesives and adhesive-dentine interface, with specific reference to chemical aspects of dental materials, particularly resin-based composites and adhesives, (polymerisation kinetics, elution of leachable components, chemical characterization of the adhesive-dentine interface).
