Biological and mechanical characterization of commercial and experimental periodontal surgical dressings.

The objective of this study was to evaluate the biocompatibility and mechanical properties of two commercially available and one experimental periodontal dressing materials. The cytotoxicity of Periobond ® , Barricaid ® and one experimental periodontal dressing based on Exothane ® 8 monomer was tested on 3T3/NIH mouse fibroblast. Genotoxicity was assessed by micronuclei formation, and cell alterations were analyzed using light microscopy.

New fluorescence and reflectance analyses to aid dental material detection in human identification.

Introduction: The identification of aesthetic dental materials during clinical dental examination can be challenging especially as patients and dental manufacturers place great emphasis on filling materials being as close as possible in appearance to the natural tooth. This makes dental identification in a forensic setting even more complicated.

Objective: The aim of this study was to develop a simple method using photographic analyses to determine differences in fluorescence and reflectance between brands and shades.

Epidemiology and Risk Factors of Maxillofacial Injuries in Brazil, a 5-year Retrospective Study.

Aim: The etiology and epidemiology of maxillofacial injuries varies widely in different regions of the world due to socioeconomic status, cultural aspects in addition to road traffic and drug consumption. The aim of this study is to determine major causes and epidemiological characteristics of maxillofacial trauma in a 5-year period.

Materials And Methods: Reports of corporal trauma (n = 25,632) from 2007 to 2011 in the Department of Forensic Medicine were analyzed as to the presence of maxillofacial injuries.
