I am not sure this is what you are looking for but... we quite recently did a work titled "Occupational Exposure to Blood and Body Fluids in a Department of Oral Sciences: Results of a Thirteen-Year Surveillance Study". You can easily find it because it is on a open access journal (The Scientific World Journal Volume 2013, Article ID 459281, 7 pages http://dx.doi.org/10.1155/2013/459281).
Dear Dr Haroon Rashid and Dr Marco Montevecchi, Thank you very much for your answer!!! These articles are very important and serve me, But I am looking for the importance exactlly. Because I am writing an article titled "the importance of epidemiological surveillance (Vigilance) in dentistry" but there are few bibliography about this exactly.
