Anthropometric technique commonly used by anthropologists and adopted by medical scientists has been employed to estimate body size for over a hundred years. With the increasing frequency of mass ...disasters, the identification of an isolated lower extremity and the stature of the person it belonged to has created problems for the investigation of the identity of some of the victims. In spite of a need for such a study, there is a lack of systematic studies to identify fragmented and dismembered human remains. The purpose of the paper is to analyze anthropometric relationships between dimensions of the lower extremity and body height. Analysis is based on a sample of middle class male (
N=203) and female (
N=108) adult Turks residing in Istanbul. The participants are mostly students and staff members of a medical school, and military personnel. Measurements taken are stature, trochanteric height, thigh length, lower leg length, leg length, and foot height, breadth, and length. Of the five variables entered into the regression analysis, all but foot breadth participate in the analysis with leg length as the first and followed by thigh and foot lengths, and finally foot height in males (
R
2). There were also individually calculated formulae for some of these measurements which provided smaller
R
2-values. Student’s
t-test to assess if there was any intraobserver error in measurements take by individual anthropometrist did not show such any statistically significant difference. In conclusion, the study suggested that estimation of a living height can be made possible using various dimensions of the lower extremity. One must consider differences between populations in order to apply functions as such to others.
Radiographic evaluation of mineralization and eruption stages of third molars using dental panoramic radiographies can be an efficient tool for chronological age estimation in both forensic sciences ...and legal medicine. The third molar tooth is utilized for dental age estimation about the age span of 15–23 years because it represents the only tooth still in development. The aim of this study is to obtain and analyze data regarding third molar development and eruption in Turkish population for dental age estimation. A total of 744 dental panoramic radiographies of 394 female and 350 male subjects aged between 8 and 22 years were examined. Third molar development was determined according to the Nolla classification system, and eruption was assessed relative to the alveolar bone level. Mandibular and maxillary third molars were generally found at similar stages of development on both sides. Nolla stage 6 (completed crown calcification) was reached at around the age of 15 in both maxillary and mandibular third molars in both sexes. Alveolar emergence was at around the age of 16 in males and around age of 17 in females. Although third molars’ eruption shows greater variability than development of third molars, data which were obtained from this study about eruption of these teeth can be supportive to development data for age estimation.
With the increasing frequency of mass disasters, identification of an isolated upper extremity and determination of the stature of the person it belonged to have created problems for investigation of ...the identity of some victims. Despite a need for such a study, there is a lack of systematic studies to identify fragmented and dismembered human remains. The purpose of this study was to analyze anthropometric relationships between dimensions of the upper extremity and body height. Analyses were based on a sample of middle class male (n = 202) and female (n = 108) Turks residing in Istanbul, Turkey. Five variables were entered into the analyses. For male subjects, forearm length was selected as the first factor, followed by hand length and finally upper arm length. For female subjects, upper arm length was selected first, followed by forearm length and finally hand length. There were also individually calculated formulae for some of these measurements that provided smaller R2 values. The study suggested that estimation of a living height could be made possible by using various dimensions of the upper extremity. One must consider differences between populations to apply such functions to other populations.
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.
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 Bengston's system, which was modified by AlQahtani et al at four points.
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.
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.
Dişlerin gelişim ve sürme aşamalarının resmedildiği atlaslar diş hekimliği uygulamalarında ve adli bilimlerde yaş tahmini amacıyla kullanılmaktadır. Bu yöntemin hem yaşayan kişilerde hem ...de cesetlerde kullanılabilmesi ve pratik olması büyük avantajdır. Özellikle çok sayıda kurbanın bulunduğu kitle felaketlerindeki kimliklendirme çalışmalarında kullanışlı ve oldukça etkili bir yöntemdir. Bu çalışma Türkiye Cumhuriyeti vatandaşı olan çocuklar ve genç erişkinlere yönelik oluşturulmuş bir diş gelişim atlasının validasyon çalışmasıdır. Yaşı ve cinsiyeti bilinen 5-22 yaş arasındaki bireylere ait başka tıbbi amaçlarla çekilmiş 80 adet panoramik diş grafisi bir görüntüleme merkezinden kişilerin kimlik bilgileri saklı tutulmak şartı ile alındı. Her bir grafideki dişlerin sürme ve gelişim aşamaları atlas yöntemi ile değerlendirilerek diş yaşı tahmin edildi. Türkiye Cumhuriyeti vatandaşı olan çoçuklara ait veriler kullanılarak oluşturulan bu atlasa göre 14 yaş ve altındaki tüm grafilerde % 95 oranında ± 1 yaş hata ile, 14-22 yaş aralığında ise % 92.5 oranında ± 2 yaş hata ile tahmin yapılabildiği saptandı. ………. ve ark. tarafından oluşturulan diş gelişim atlasının adli amaçlı yaş tahmininde ve özellikle de kitlesel felaket kurbanlarının kimliklendirilmesi çalışmalarında yararlı ve kullanışlı olduğu anlaşıldı.Anahtar kelimeler: Dişlerden yaş tahmini, diş gelişim atlası, panoramik grafi, Türkiye popülasyonu.
Amaç: Bu çalışmanın iki amacı vardır. Birincisi ağız ve diş sağlığı tanı ve tedavi birimlerinde çalışan diş hekimlerinin maruz kaldıkları ve tanık oldukları şiddetin niteliklerinin belirlenmesidir. ...İkincisi ise yaşanan şiddet olayı sonrasındaki sürecin ortaya konulmasıdır.Gereç ve Yöntem: 1 Temmuz 2014 - 31 Aralık 2014 tarihleri arasında İstanbul’daki kamuya ait ağız ve diş sağlığı merkezleri ile üniversitelerin diş hekimliği fakültelerinde görev yapan diş hekimlerine yönelik bir anket çalışması yapıldı. Anket formu üç bölümden oluşturuldu. Birinci bölümde demografik veriler, ikinci bölümde şiddetin sebepleri ve şiddetin önlenmesine yönelik alınabilecek önlemler, üçüncü bölümde ise maruz kalınan şiddetin niteliklerinin belirlenmesine yönelik sorular bulunmaktadır.Bulgular: Katılımcıların %48.5’i (n=32) tüm meslek hayatları boyunca en az bir kere şiddete maruz kaldığını, şiddete maruz kaldığını belirtenlerin %65.6’sının (n=21) da son bir yıl içinde şiddetle karşılaştığı saptandı. Maruz kaldıkları şiddet türü sorgulandığında, %71.9’u (n=23) sadece sözel, %18.7’si (n=6) ise hem sözel hem de fiziksel şiddete maruz kaldıklarını belirtti. Toplumda şiddet vakalarının arttığına inananların oranı %95.5 (n=63) bulundu. Anket çalışması yapılan kurumda şiddet vakalarının arttığına inananların oranı %69.7 (n=46) ve şiddetin engellenebileceğini düşünenlerin oranı ise % 86.4 (n=57) olarak belirlendi.Sonuç: Çalışma küçük bir grubun bu konudaki görüşlerini yansıtmakla birlikte diş hekimlerinin de sağlık alanındaki şiddetten etkilendiğini göstermektedir.Anahtar Kelimeler: Diş hekimleri; Fiziksel şiddet; Sözel şiddet; Şiddet

Symptoms of bicuspid aortic valve usually occur in the age group of 50–70 years, but rarely, it can also lead to sudden unexpected death in infancy and early childhood. The autopsy of a 2‐month‐old ...baby boy, found dead in his cot, revealed the heart weight as 25 g, and the macroscopic examination showed the circumference of the aortic valve consisting of two leaflets as 8 mm. The thickness of the left ventricle, right ventricle, and septum was measured as 8, 7, and 10 mm, respectively. Microscopically, the heart revealed hypertrophic changes of myocytes. Subendocardial areas displayed necrosis of myocytes, and severe and diffuse ischemic changes characterized by loss of myofibers and vacuolization. Interstitial pneumonia was identified in the lungs. Death occurred as a result of a congenital bicuspid aortic valve obstructing the left ventricular outflow tract complicated by lung infection. As there are only a few reported cases in infancy, and congenital bicuspid aortic valve can lead to sudden unexpected death, this case is presented to the forensic community.
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 Bengston's 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.
