| To investigate the feasibility of application of digital images of the palatal rugae in forensic identification. One hundred patients, consisting of 50 males and 50 females, who received treatment between January 2015 and June 2015 at Shanxi Medical University Stomatological Hospital, China, were included in this study. High-resolution digital image of the palatal rugae was taken from each patient using a digital SLR camera and then processed using a digital image recognition system, including noise reduction, contrast enhancement, image segmentation, feature extraction, edge detection and information matching. Using an MATLAB software system, match results and the time taken by each operator for information matching were recorded. The digital image... |

| This study aims to explore the role of palatal rugae pattern in forensic identification by coding of palatal rugae characteristics, and to construct a forensic identification system for oral palatal rugae. One hundred models were included in this study for a systemic coding of palatal rugae pattern based on the shape, quantity, location, and distribution of palatal rugae. Among the involved 100 models, palatal rugae types varied among individuals and palatal rugae pattern was different between men and women, even between two sides in the same individual. Palatal rugae pattern can be used for forensic identification of oral soft tissue and this study proposes a new means for the identification by coding of palatal rugae pattern based on the shape, quantity,... |

| Establish a person's identity can be a very complex process, one of the main objectives of the forensic sciences. The analysis of the teeth, fingerprints and DNA comparison, are probably the most used technics, allowing fast and secure identification processes. However, these techniques can not always be applied, in some cases, it is necessary to apply different and less known techniques. In this work, a systematic analysis of the shape and dimensions of the palatal rugae was performed. We analyzed 120 subjects of both sexes, between 15 to 20 years olds, fully dentated, and by calcorrugoscopy were determined the shape, size, number and position of the palatal rugae. The most prevalent palatal rugae shape was sinuous (43%) followed by curve (27%), line... |
