  Tooth enamel is the hardest and most highly mineralized substance of the body and with dentin, cementum and dental pulp is one of the four major tissues which make up the tooth in vertebrates. The unique microstructure of enamel resides fossilized tracks of its growth process. These tracks represent the incremental growth of enamel. Forensic odontology is a vital and integral part of forensic science. Essential data could be derived by the study of the enamel structure and contribute in dental identification, age estimation procedures and archaeology, anthropology and forensic researches. Further advances in image analysis and computer technology would enhance the knowledge and improve the accuracy of methods used in Forensic odontology field.

  In certain circumstances, teeth may appear with a discoloration in post-mortem examinations. This phenomenon is called pink teeth. Pink teeth are caused by release of hemosiderin due to the breakdown of haemoglobin of red cells inside the pulp. The hemosiderin then is released inside the dentine tubules and discolour the teeth. Nevertheless, this situation can be reported in living humans, in endondontically treated teeth and in other conditions in primary teeth, etc. There are many reports of pink teeth in the literature, thus the usage of proof in Forensic odontology for a positive identification of a body remains under controversy.

  Historically, the civil procedures in England and Wales follow an adversarial approach. The criminal procedures started to develop an adversary system only in the 18th century. Since medieval times, the law system has grappled with issues as to when and how to use expert knowledge to assist it in the resolution of disputes. The earliest records of expert witness date back to the 14th century and involve cases in which surgeons were summoned to establish as whether a wound was fresh. The role of an expert witness is to assist the court on matters within their expertise. Courts rely on expert witness testimony in most civil and criminal cases to explain scientific matters that may not be understood by the judge or the jury. It is especially important for the dentist to demonstrate confidence in his testimony especially during the cross-examination. Above all the expert witness should keep in mind during the time of intensive interrogation that it is not him on trial even though it may seem to be at some times.

  Intimate Partner Violence (IPV) is a type of abuse that occurs between two people who are involved in a close relationship. Many times emotional abuse is the first sign followed by the others. This is a well-known phenomenon reported in psychology for abusive behaviour often leads to physical or sexual assaults.

  In this part (II) we present the variety of reasons concerning the appearance of IPV which in no case do they justify this brutal action. There are also several factors of IPV behind this brutal behavior. It is really important to stress that there is no excuse relating to the violent behavior of the abuser. Moreover, since the victims feel ready to share these abusive experiences with the authorities, the clinical doctors and dentists, it is a necessity for the doctor/dentist to be aware of all the indications leading to the conclusion that we have a case of IPV. Having a physical examination combined with the strange behavior of the suspected victim, one can find the truth behind the story of a potential accident and prevent any further brutal behavior connecting with the victim. In concluding it is important to examine cases of domestic violence, the victim’s profile, all the dangerous consequences relating to IPV as well as approaches to help dealing with this phenomenon.

  The term of bite marks is defined as the trauma caused on the skin from the contact of the teeth with or without the contribution of the soft oral tissues (lips, tongue) and which depicts the form of particular oral structures. The use of bite mark evidence in criminal or abuse cases has been widely accepted by law enforcement agencies and courts for many years. Several historical data reveals the significance of the proper recognition and identification of bite marks since the 17th century. With the evolution of Forensic Odontology, a plethora of new tools and equipment can be used to positively identify an assailant through a bite mark on the victim’s tissues. The current case report aims to present a victim’s ear loss due to a human bite during a fight and with this occasion to refer to the up-to-date standard elements of human bite marks regarding the concurrent categorization, the frequencies of incidences according to anatomical area, sex and type of crime.

  The aim of this study was to evaluate the accuracy of two methods for the bite mark analysis in foodstuff. For the purposes of this study ten suspects participated as possible perpetrators of a bite mark found in a fresh apple which was seized at a supposed crime scene. The sample was kept in a sealed bag and stored in a fridge. The following day researchers applied the technique of obtaining an impression of the bite mark in the apple using light body vinyl polysiloxane which was injected without pressure from a central point to the bite mark periphery. A ring was constructed as barrier using a heavy body vinyl polysiloxane. The next stage was to pour model from the bite mark impression with the use of dental stone. Next step was to take dental impressions of the possible suspects using alginate impression material (protesil) and pour dental casts of the dentitions with dental stone. About 2 independent forensic dentists compared the pattern of the bite mark with the dental casts of the suspects using two different methods each time: the docking procedure (direct method) and the computer-assisted overlay production technique with Adobe Photoshop CS4 software (indirect method). The results of this study showed that the computer-based method for bite mark analysis was as accurate as the docking procedure in cases with bite marks in an apple and may be useful in a variety of substrates.

  Domestic violence and child abuse has become one of the latest social concerns and this trend can be clearly seen in the increasing number of reported cases. The aim of this case report is to present a case of physically abused child 11 years old. The 11 years old child had facial and oral traumas, in particular bruises and abrasions in the frontal area, the upper lip and the periorbital area about 65% of child abuse injuries involve head, neck or mouth areas. So, dental personnel may be in a good position to note abuse. As dentists, researchers are likely to be in contact with children who have been exposed to family violence the head and face are often easy targets of the abuse. The dental team that is alert to the fact that many children are been abused and that many of these abused children have injuries to the head and around the mouth may be able to identify an abused child and institute steps that might save the child’s life.

  Elder abuse is commonly defined as a single or repeated act or lack of appropriate action occurring within any relationship where there is an expectation of trust which causes harm or distress to an older person. A lady 81 years old presented to the hospital with dento-alveolar fracture of the left maxilla. The associated bruising of the left facial region was of great importance. The home care provider gave confused details about the fall injury. The patient had affected communication skills due to dementia disease. The suspicion of fall associated to abuse generated from the different views between the two persons. The mental status of the patient occasionally may seriously complicate obtaining an accurate history of the trauma. Therefore, the identification of such a pathological condition is complicated having as a consequence many cases to remain with incorrect diagnosis. The proper management of a patient of this type of injury will be discussed. Abusive behaviour by family carers towards people with dementia is common with a third reporting important levels of abuse and half some abusive behaviour. The role of dentist by contacting the responsible authorities such as forensic (medical, dental and psychiatric or psychological), social and other implicated local societies by law should be emphasized. The dentists should be aware of this abnormal behaviour in order to prevent and assess properly any suspected abuse in elder women or men.

  Violence against women often have signs of injury that are readily visible to dentists. Dentists have a moral and legal obligation to recognize and report suspected abuse and illustrations. The purpose of this study is to present a case of Battered Woman Syndrome (BWS), assist in diagnosing abuse and ensure that we give the criminal-justice system the tools it needs so that women’s rights are turned into reality.

  The trauma caused on the skin from the contact of the teeth with or without the contribution of the soft oral tissues (lips, tongue) is defined as a bite mark. They can be caused either by humans or by animals and are usually found in two kinds of cases: crimes and homicides with and without sexual activity and child abuse. Bite marks can be found on both victims and assaulters. In mortal combat situations such as the violence associated with life and death struggles between assailants and victims, the teeth are often used as a weapon. Indeed using the teeth to inflict serious injury on an attacker may be the only available defensive method for a victim. The frequency of occurrence of bite injuries at specific locations varies with the type of crime and sex and age of the victim. This case report aims to present a victim who was involved in a fight and the facial bite mark on the right part of the face was the only evidence for that. The concurrent methodology on collecting data from the mark and the possible suspect as well as the comparison techniques is also reported.

  Seniors can be vulnerable to abuse for many reasons in many different aspects of life. Elder abuse refers to any action or inaction that threatens the well-being of a senior. Abuse can occur at home or in a residential facility at the hands of a family member or another caregiver. But abuse is not only about broken bones and bruises and marks seen on the body of the victim. There can be different types of elder abuse. The senior may be subjected to more than one type. Most common types are: physical abuse, sexual abuse, inactive abuse, active abuse, self-neglect or abandonment, financial exploitation and psychological abuse. Signs and symptoms can be noticed by neighbors and be reported. It is of major importance that the dentist/doctor is qualified and informed of the protocol on handling cases of elder abuse. Usually elder abuse is the well-kept secret of a family and it is a problem within families. Unfortunately elder abuse can happen to any family. The topic of elder abuse is difficult because all practitioners wish that it did not happen. Cases of family violence are hard to deal with because we know that they are not the result of some disease or accident. Instead, they are done deliberately. Although, victims are often reluctant to report their abuse, the fact that about 75% of physical injuries are inflicted to the region of the head, face, mouth and neck places dentists in a very good position to recognize the signs of abuse and take steps to intervene.

  Human beings biting themselves or other humans is something relatively common in Forensics. On the contrary is a very rare subject in Art. The aim of this study is to show nine cases in European painting where this action is depicted. They include frescoes, paintings on wood using tempera and oil colours on canvas, one engraving and two icons. Chronologically they span from 15-19th century. Four of them depict scenes from the Last Judgement of Christ, three of them are inspired from Dante’s Inferno as described in the Divine Comedy and the last two are marginal scenes of icons showing the life of St. Andrew the Apostle. Although, these paintings are not the only ones about this subject they are good examples. A thorough research in sculpture and minor arts may yield other examples.

  Forensic Odontology uses a variety of methods in identification of human remains. One of them is done by the use of facial mapping which involves the use of antemortem photographs and comparison with the postmortem skull. The current techniques are: morphological comparison, photoanthropometry or photogrammetry and photographic superimposition. Despite the fact that these techniques are complex and substain a variety of technical restrictions, they are widely approved and applied.

  The human face holds key information about identity such as age, sex and ethnicity, information that enables the identification of a single individual. The photographs are used commonly in identifications procedures so that lay people can make cursory identification by comparing the suspect in question with his/her photograph. The other race effect appears to have a significant influence in the face recognition process and facia mapping analyses.

  Recognizing the identities of people is a basic requirement for the establishment and maintenance of social act and communication and face recognition is an ability that humans develop and become very skilled as they grow up. Recognition has always been a very intriguing and highly researched topic and implies the tasks of identification or authentication. It is apparent that face recognition for human beings involves more than simple tasks of shape matching of features and face. Despite the fact that is not fully understood how humans recognise people what is known today is that they use a combination of identifiers such as height, voice and facial features.

  In forensic practice, there is a frequent demand for comparison of facial images of perpetrators and suspects. Photoanthropometry is the science of measurements from precisely defined marker points of the face and is commonly used to provide opinion evidence of identity from examination of facial pictures. In facial mapping, it is based on quantitative analysis on measurements of the distances and angles between anatomical facial landmarks and the generation of indices based on them.

  Verification of the identity of an unknown person is one of the most essential aspects of forensic practice. The reliability of identification of human remains by comparison of antemortem and postmortem radiographs of frontal sinus is well established as appear to be unique in each individual. A frontal sinus comparison can be particularly useful when an individual is edentulous. However, the use in practice of frontal sinus remains limited. The aim of this study is to present the method of identification through comparison of frontal sinus outlines radiographs.
