Development of dental charts according to tooth development and eruption for Turkish children and young adults

Purpose In this study, we aimed to develop dental charts for Turkish children and young adults of both genders within the age group of 4.5-22.5 years according to tooth mineralization and eruption in a format similar to that proposed by AlQahtani et al. Materials and Methods In total, 753 digital panoramic radiographs from 350 males and 403 females were assessed. The permanent teeth were evaluated according to the classification system described by Demirjian et al. The eruption stage was assessed with Bengstons system, which was modified by AlQahtani et al at four points. Results Teeth generally developed earlier in females than in males. This was particularly notable in the age group of 5-14 years. However, this difference was usually visible in only one stage, not in all teeth. It has been determined that the mixed dentition period ended with the shedding of the second deciduous molars in both genders. Conclusion The dental charts presented here included information that could be beneficial to dental clinicians in making appropriate diagnosis and planning orthodontic and surgical procedures. These charts also provided datasets for preliminary dental age estimation in Turkish children and young adults.

Felaket Kurbanlarının Kimliklendirilmesinde Diş Kayıtlarının Önemi

Identification of victims after natural or unnatural disasters is a difficult and time consuming process. Specialists who are trained in forensic dentistry field, take part in groups formed for disaster victim identification. One of the primary and most important practices of forensic dentistry is the identification of bodies which have no relations to identify or are deformed greatly, after a mass fatality. In this field, techniques based on the comparison of dental records have come into prominence. The objective of this article is to give practical information regarding the usage of dental records in mass fatalities. Dental identification is based on the comparison of antemortem and postmortem records for the features such as; restorations, dental caries, missing teeth and prosthetic treatments. Hence, it is necessary to keep organized and detailed records, which include all of these information, in accordance with international norms and facilitate the relevant experts to reach and work on such records in a case of mass disaster. The comparison of dental records can be performed by computer software as well as manually. However, it is considered as the most accurate approach to use both techniques together.

Acil tedavi birimlerinde adli olgudan biyolojik materyal alınması ve gönderilmesi

Hastanelerin acil tedavi unitelerine basvuran adli olgular ile ilk temas edenler bu birimlerde gorevli hekim, hemsire ve diger saglik personelidir.

Role of bite mark characteristics and localizations in finding an assailant

The location, size, and number of bite marks can be used as a beneficial indicator of the crime type and feasible group of suspects. This study aims to present information about the bite mark locations, the bite mark characteristics, and the perpetrators profile based on three cases which were carried out by the same biter. The attack bites, which observed in all of the three cases, were characterized by serious wounds and tissue loss. Analysis of bite mark characteristics and bite mark localizations of these three cases by the relevant experts provided helpful information for the police units which searched for the assailant. But, in order to conduct criminal profiling from bite marks objectively, the number of case series is advised to be expanded.

The usage of third molars to determine legally relevant age thresholds in Turkey

From a forensic perspective, attaining the ages of 12, 15 and 18 is particularly important with respect to the Turkish Penal Code (TPC). The aim of this study is to obtain data regarding third molar development in the Turkish population for age estimation and to investigate the contribution of third molar development to age estimation in relation to the TPC. The study was applied with panoramic radiography on 379 male and 405 female subjects. The mineralization status of the third molars were evaluated on the basis of Demirjian’s classification system. It was determined that ‘0’ and ‘A’ stages for under-12 years of age, ‘B’ and ‘C’ stages for under-15, ‘D’ stage for under-18, ‘E’ and ‘F’ stages for over-12, ‘G’ stage for over-15 and ‘H’ stage for over-18 were specific stages for both genders. Specific stages that are detected according to the developmental stages of the third molars were not found to be adequately precise for distinguishing legal age thresholds. However, this study shows that matured third molars (reaching H stage) are indicative of an individual’s being over 18 years of age for both genders in Turkey.
