A estimativa da idade a partir de remanescentes ósseos é um desafio da ciência forense, principalmente em adultos. Os ossos da cabeça, do pescoço e os dentes apresentam maior resistência e, frequentemente, são as únicas peças disponíveis para perícia. Este estudo teve como objetivo revisar criticamente os métodos disponíveis para a estimativa de idade a partir remanescentes ósseos da cabeça e do pescoço, bem como dos dentes na prática forense. Foi realizada uma revisão da literatura, utilizando a base de dados PubMed para as buscas com os seguintes descritores: “cranial sutures”, “teeth mineralization”, “cervical vertebrae”, “hyoid”, “age estimation” e “human identification”. As buscas de artigos foram restritas aos últimos dez anos. Contudo, livros, artigos clássicos e teses foram incluídos, mesmo que tenham sido publicados há mais tempo. A revisão da literatura mostrou que a idade de fechamento das suturas deve ser utilizada em associação com outro parâmetro devido à ocorrência de variações frequentes. O ângulo da mandíbula pode oferecer informações importantes para estimar a idade, porém a mineralização dentária a partir da utilização de exames de imagem ou técnicas histológicas oferecem subsídios para estimar a idade com maior acurácia. Os ossos do pescoço podem ajudar a estimar a idade, porém não devem ser utilizados isoladamente. Em conclusão, os dentes e ossos da cabeça e do pescoço podem ser utilizados em complemento à análise de outros ossos para estimativa de idade. Contudo, quando são as únicas peças disponíveis, o grau de fechamento das suturas, o ângulo da mandíbula e a mineralização dentária podem oferecer subsídios suficientes para estimar a idade, principalmente quando analisados juntamente a exames de imagem, técnicas histológicas e em associação com os ossos do pescoço.

Cranial suture closure has been regarded as an unreliable method for age estimation due to the large amount ofvariability in the commencement, progression and termination of fusion. The Hamann Todd Osteological Collectionwas used to examine the sagittal, coronal and lambdoid sutures in an attempt to determine the impact of sex and ancestry on synostosis. The sagittal does not appear to be impacted by sex, but in the coronal and lambdoid sutures,significant sex-based differences were noted. Generally, females exhibited greater progression than males, butsynostosis was more strongly related to age in males. Stronger age-score correlations were present in black individuals compared to white individuals. This questions the application of current cranial aging methods, which do not address sex- and population-based differences in the commencement, progression and termination ofsutural fusion.

Objectives: To compare Demirjian Dental scoring method with Greulich-Pyle (GP) Skeletal method of age estimation in pubertal children. Materials and Methods: Sample of the study included 267 male healthy subjects of 11-16 years of age group.. Demirjian Scoring system was utilized to evaluate the orthopantomograms to assess their Dental age and the Hand-Wrist radiographs were analyzed to calculate the skeletal age by utilizing GP atlas. Chronological age was obtained from the date of birth of the subject .Both methods were compared with one another and with the chronological age. It was a cross-sectional study and only healthy male subjects without any clinical abnormalities were included in the study. Results: A total of 267 male subjects of 11-16 years of age group were assessed by Demirjian and Greulich Pyle Methods. Both were compared with Chronological Age. Data obtained was statistically analyzed and the Student “t” test was applied in the study population. The mean difference between Chronolgical age and dental age was 0.69years and that of chronological age and skeletal age was 0.87 years. It was observed from dental age assessment that it does not differ much from the skeletal age. Conclusion: It was concluded that Demirjian method of Age Estimation is more precise than Greulich Pyle method of Age Estimation. Furthermore both methods can be used selectively in Medicolegal cases to access bone age which can be easily correlated to chronological age.

Age changes cause major variations in the appearance of human faces. Due to many lifestyle factors, it is difficult to precisely predict how individuals may look with advancing years or how they looked with "retreating" years. This paper is a review of age variation methods and techniques, which is useful to capture wanted fugitives, finding missing children, updating employee databases, enhance powerful visual effect in film, television, gaming field. Currently there are many different methods available for age variation. Each has their own advantages and purpose. Because of its real life applications, researchers have shown great interest in automatic facial age estimation. In this paper, different age variation methods with their prospects are reviewed. This paper highlights latest methodologies and feature extraction methods used by researchers to estimate age. Different types of classifiers used in this domain have also been discussed.
