Scientific journals focusing on dental materials

Two journals in the Science Citation Index (SCI) database focus exclusively on dental materials: (1) Dental Materials and (2) Dental Materials Journal.

Dental Materials is published monthly by the Academy of Dental Materials and is currently ranked 4/55 in the Dentistry, Oral Surgery & Medicine discipline and 5/19 in the Materials Science, Biomaterials discipline. Its impact factor for 2008 is 2.941. It is available through ScienceDirect but requires personal or institutional subscription for full text access. Abstracts can be accessed for free. January 2010 issue of Dental Materials is a free sample and full texts can be downloaded as PDF files. This issue is available HERE.


Dental Materials Journal is published bi-monthly by the Japanese Society for Dental Materials and Devices and is currently ranked 51/55 in the Dentistry, Oral Surgery & Medicine discipline and 15/19 in the Materials Science & Biomaterials discipline. Its impact factor for 2008 is 0.713. Dental Materials Journal is available through FreeMedical journals or at publisher's website HERE. All issues are free and full texts can be downloaded as PDF files.

Though I access full texts in most dental journals through my University online library, occasionally there are articles which cannot be obtained this way. Another way of obtaining an article in its entirety is to send a reprint request to the corresponding author. Fortunately, there is an email address attached to most abstracts on PubMed/MEDLINE. I have been able to obtain almost all articles from the authors whom I sent reprint requests. The only problem may arise when the provided email address becomes inactive. This often happens when an author changes institutions and institutional email addresses. This is why I, for example, always provide my gmail address for correspondence when submitting an article for publication.

Summary

The end of the year is usually a period when many people like to summarise their achievements and make future plans. I've been using google analytics for slightly more than 3 months now. It's really great to be able to see the statistics about one's blog.

Dental-materials.blogspot.com had exactly 1000 visits between Sept 21 and Dec 25 from 72 countries/territories. The list of top 10 countries with the greatest number of visits includes the USA, India, Egypt, Germany, Indonesia, Canada, Turkey and Iran.




Of 702 absolute uniqe visitors, about one third were returning visitors with more than 300 visits :-) The average time on site was 00:02:26 with an average of 1.90 Pages/Visit.

More than half of all visits came through search engines, Google being the most popular, as expected. About the same number of visits came as direct traffic and from referring sites, such as blogger.com, twitter.com, blogcatalog.com, linkedin.com, facebook.com etc.



Interestingly, this blog appeared in search engines not just when 'dental materials' were used as keywords. In fact, the visitors of this blog entered more than 400 keywords, such as 'dental materials journal', 'mta dental material', 'filtek silorane', 'mta in endodontics', 'free dental material journal', 'books of dental materials' etc.

So, it's been an exciting period for dental-materials.blospot.com and I hope this blog will be even better in the future. I'd like to thank all the visitors and wish Merry Christmas and a very happy and prosperous New Year.

PhD Scholarship

Manufacturing And Characterisation Of Titanium Based Dental Implant

University of Sheffield - Department of Mechanical Engineering

Application deadline: 07 January 2010.

Call for abstracts: 88th General Session & Exhibition of the IADR

88th General Session & Exhibition of the IADR
Barcelona, Spain, July 14-17, 2010.
www.iadr.org

Abstracts can be submitted online HERE. The deadline for abstract submission is February 5, 2010. As on previous IADR conferences, one person may present only one abstract but can be co-author on an unlimited number of abstracts.

More than 4500 delegates are expected and more than 3000 abstracts submitted. There will be oral and poster discussions as well as traditional poster sessions. All delegates will receive continuing education credits according to the ADA CERP.

The new way of abstract presentation is through poster discussion sessions designed for up to 7 individual presentations. Abstracts in these sessions will be presented as posters with up to 3 PowerPoint slides in addition. Each presentation will last for 5 minutes followed by 2 minutes of discussion.

Posters will be displayed vertically, rather than horizontally. Poster dimensions will be 0.93 m (width) x 2.22 m (height).

There will be more than 20 subject areas including dental materials, cariology, dental anesthesiology, implantology, microbiology, mineralized tissue, neuroscience/TMJ, oral&maxillofacial surgery, periodontology, prosthodontics, pharmacology, pulp biology etc.

More information and detailed instructions can be found HERE.

Poll: 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 nowadays 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.



(a) Three-step etch-and-rinse systems: acid etching with phosphoric acid followed by the application of primer and bond from separate bottles;
(b) Two-step etch-and-rinse systems: acid etching with phosphoric acid followed by the application of primer and bond which are in one bottle;
(c) Two-step self-etch systems: self-etching primer and bond are in separate bottles;
(d) One-step self-etch systems (also known as "all-in-one" systems): all components are in one bottle

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

Textbook of Restorative Dentistry

It is my pleasure and honour to announce that the Textbook of Restorative Dentistry (original title: Osnovi restaurativne stomatologije) has been published by my professors at Belgrade University School of Dentistry Dept. of Restorative Dentistry and Endodontics: Slavoljub Zivkovic, Mirjana Vujaskovic, Katarina Pap, Djurica Grga, Aleksandra Lukic and Nevenka Teodorovic.

This is the official textbook for undergradute students but may be very helpful to dental practitioners who have some questions regarding restorative procedure.

The book is divided in four parts. Part I presents the biology of pulp-dentine complex, its ultrastructure, but also important physiological and biochemical aspects. This chapter also explains the basics of caries etiology, pathogenesis and diagnostics.

Part II details the equipment and instruments for restorative treatment as well as techniques for caries removal.

Part III explains cavity preparation procedures according to traditional Black's principles and the adhesive cavity preparation for resin-based materials. Cavity preparation for indirect restorations is also explained. Some basic gnatological requirements in restorative treatment are mentioned in Part III.

Part IV addresses all dental materials in restorative dentistry. It contains basic clinical characteristics of materials for temporary fillings, for pulp cappings, amalgam, glass-ionomer cements, resin-based composite materials and adhesive systems as well as materials for indirect restorations.
