Dental materials - online learning resources
Dental materials lectures by professors Stephen C. Bayne and Jeffrey Y. Thompson for UNC and Michigan DDS students. Other users need special permission but the files can be accessed and viewed free of charge. The lectures cover topics from operative dentistry (pulpal capping, adhesives, composites, amalgam, glass-ionomer cements), fixed prosthodontics (impression materials, waxes, alloys, ceramics) and removable prosthodontics (alloys, bases and teeth). The files are in the form of PDF and PPT handouts, self-study modules and audio files and include study and discussion questions.
University of Berkley webcasts - Structural Aspects of Biomaterials , Instructor Lisa Pruitt. Tooth and bone tissues are addressed in a basic manner necessary to understand the interaction with materials. Dental materials (filling materials, implants) are discussed in terms of mechanical and structural aspects. Mechanical design for longevity includes topics of fatigue, wear, and fracture. Very well explained and understandable to dentists without almost any previous engineering knowledge. This webcast is free to view but cannot be downloaded.
Dental materials webinars by various speakers at dentallearning.com. There are 13 webinars covering topics such as contemporary adhesives, dentine bonding , anterior and posterior composite restorations, sealants and glass ionomers, zirconia, impression materials, CEREC restorations. Among the speakers are renowned lecturers Dr David Pashley and Dr Jorge Perdigao who address the advances in adhesive dentistry and explore the science of dentine bonding. The cost of webinars by Drs Pashley and Perdigao is USD$35 whereas most other webinars direct you to Kerr Learning source where they can be viewed but registration (free) is required. There are even more free webinars at Kerr Learning. All these webinars are CE approved.
Dental ED live lectures and online courses - cost from USD$50 to USD$260. Online courses include composite restorations, endodontic obturation, dental implants, porcelain building techniques, shade selection, direct laminate veneers, zirconica restorations. Upcoming live lectures can be viewed at Dental ED website. Basically, all lectures and courses are audio-visual presentations with more or less theoretical background but with excellent clinical cases.

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.

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
