Forensic Medicine and Anatomy Research (FMAR) , 2013, DOI: 10.4236/fmar.2013.13011
Abstract: This study proposed to evaluate the precision of Nicodemo, Moraes and Médici method and the method proposed by Demirjian and compare both methodologies in relation to the efficiency and applicability in the Brazilian population. The sample consisted of 124 panoramic radiographs of subjects in the age group from 7 to 16 years old, 66 patients female and 58 male. For the comparison of the genders in relation to the average percentage difference, the t-Student test was considered. In average the method of Nicodemo, Moraes and Médici presented for the female gender an estimated result 14.7% lower than the real age. For the male gender the estimative obtained was that for each year of variation of the real age the method of Nicodemo estimates a variation of 0.48 years, with a confidence interval of 95% given by (0.43; 0.54). For the method of Demirjian the result was that for each year of variation of the real age the method of Demirjian estimates a variation of 1.00 year, with a confidence interval of 95% given by (0.85; 1.15) for the male gender and 0.96 years, with a confidence interval of 95% given by (0.84; 1.08) for the female gender. It is concluded that the Method of Nicodemo, Moraes and Médici tends to underestimate the real age and that as the real age increases this underestimate becomes higher. Now, the method of Demirjian tends to over- estimate the real age in 8.2 months for the male gender and in 7.1 for the female one in average.

Abstract: objective: this study describes a forensic case of incinerated remains of a man that were identified using information found in his orthodontic records. methods: incinerated remains of a man were found inside a car. after forensic crime scene investigation and postmortem and radiographic exams in the forensic department, forensic experts found that the victim had a fixed orthodontic appliance, supernumerary teeth in all quadrants, partially erupted third molars and amalgam restorations in some surfaces of several teeth. as the individual's soft tissues were substantially destroyed, identification using fingerprints was not the ideal choice. after orthodontic records were handed in by the family, his clinical chart, radiographs, intra- and extraoral photographs and impressions were analyzed, and these data were compared with previously collected information. results and conclusions: forensic dentistry examination revealed 20 concordant points in specimen examination and orthodontic records, which enabled the establishment of a positive correlation between the cadaver under examination and the missing person and eliminated the need for further analyses (dna tests) to identify the victim.

Abstract: Introduction: Forensic Dentistry is an area of Dentistry related to Law. Among its goals is the execution of human identification, defined as the process of determining the person’s identity. The forensic dentist uses, in this process, ante-mortem records and data for comparison with post-mortem information obtained from the examination of the body. Objective: To describe the process of identification of a charred corpse by using dental records. Case report: The human material remained from a charred corpse was sent to an anthropological and dental analysis for identification purposes. This employed the analysis of the corpse examination and odontological records. Conclusion: The identification of the victim in this case points out to the need of an interdisciplinary work between Forensic Medicine and Dentistry in situations which other routine identification processes cannot be applied, highlighting the importance of the Forensic dentist for the final solution of the case.

RSBO , 2012,
Abstract: Introduction and objective: The main exogenous factors limiting the retrieval of information from human remains are fire and accidents involving high temperatures. Teeth, due to their relatively high degree of chemical and physical resistance, offer the possibility for the recovery of genetic material, becoming important in forensic cases. With the aim to contribute to a standardization of the protocols employed in DNA extraction and analysis, it was evaluated the integrity of DNA recovered from dental roots submitted to high temperatures, simulating what happens to burnt people. Material and methods: Extractions of genomic DNA were made from the dental root after exposure to high temperatures (600oC, 800oC and 1000oC), during 10, 30 and 60 minutes. Results and conclusion: After molecular analysis through PCR technique, it was verified that DNA amplification of the samples was not possible at any of the periods and temperatures analyzed.

Abstract: saliva is usually deposited in bite marks found in many homicides, assault and other criminal cases. in the present study, saliva obtained from volunteers was deposited on skin and recovered for dna extraction and typing in order to evaluate its usefulness for practical case investigation and discuss the contribution of forensic dentistry to saliva dna typing. twenty saliva samples were colleted from different donors and used as suspects' samples. five of these samples were randomly selected and deposited (250 μl) on arm skin. saliva was collected from skin using the double swab technique. dna from saliva and skin-deposited saliva samples was extracted by the phenol-chloroform method. dna samples were amplified by pcr for dna typing using a set of 15 strs. the recovery of dna from saliva deposited in the skin was 14 to 10 times lower than dna quantity from saliva samples. dna typing was demonstrated in 4 of 5 deposited saliva samples, the likelihood ratios estimated for these samples based on data of the brazilian population were 1:11, 1:500, 1:159.140 and 1:153.700.123. our results indicate that standardized procedures used for dna collection and extraction from skin-deposited saliva can be used as a method to recover salivary dna in criminal cases. however, it is important to observe that dna recovery in forensic samples can be difficult. this study suggests that the analysis of saliva deposited on skin be incorporated into a criminal investigation since it may have great discriminatory power.

Annals and Essences of Dentistry , 2010,
Abstract: The subject of Forensic Odontology has been generating as an area of emphasis for all interested and properly trained dentists in all hazards response. Many States have recognized the role of forensic dentist in the areas of emergency/hazard readiness. Forensic Odontology or Forensic Dentistry has been a discipline within the oral medicine fold and has been a well-accepted role for dentists. When the Tsunami in the Tamilnadu in 2001 and Bomb blasts in Mumbai in 2008 struck the people , another facet in the role of dentists and dentistry in emergency response as a forensic expert came to the collective consciousness of oral health professionals. The dentists participating in such events should be properly trained to have a meaning full role in disaster response. The dental evidence in forensic investigation is legally accepted. However there are certain pitfalls associated with the various methods in forensic dentistry. In this review various methods employed in the forenic odontology for personal identification such as Bite marks, Cheiloscopy , Rugoscopy , photographs and radiographs are discussed.

RSBO , 2012,
Abstract: Introduction: The uniqueness of dental morphology plays an important role in Forensic Odontology, especially for human identifications, in which a single tooth can provide information for dental identification. Objective: To address the importance of a permanent lower canine with two roots for dental identification considering the internal and external morphology of the canine roots. Case report: To report a forensic case in which a two-rooted permanent lower canine was found in a decomposed human body. Conclusion: Although the victim was not identified by the dental parameter, it was observed that this type of morphological variation is of little incidence in some populations, therefore constituting a valuable tool for dental human identifications.
