ABSTRACT

O estágio de desenvolvimento humano é intimamente relacionado à sua maturidade óssea ou dentária, sendo essencial para a escolha do tratamento de alterações dentofaciais em crianças e adolescentes por ortodontistas e odontopediatras. Existem diversos indicadores biológicos para determinar a maturação do indivíduo, como a idade cronológica e as alterações hormonais, porém esses indicadores podem sofrer interferências. Visando uma determinação de desenvolvimento e dos picos de crescimento mais precisa, para um melhor diagnóstico e plano de tratamento, foram desenvolvidos diversos métodos para determinar a idade esquelética e a idade dentária, sendo estes a avaliação da maturação carpal, da morfologia das vértebras cervicais, da fusão óssea da sincondrose esfeno-occipital e da sutura palatina mediana, bem como dos estágios da calcificação dentária. A avaliação das radiografias de mão e punho é o padrão ouro da predição da idade esquelética, e sua correlação com outros métodos já é evidente. Sendo assim, é possível utilizar a avaliação das vértebras cervicais e das idades dentárias de Nolla e Demirjian.


The stage of human development is closely related to bone or dental maturity, being essential for the choice of treatment for dentofacial changes in children and adolescents by orthodontists and pediatric dentists. There are several biological indicators to determine an individual's maturation, such as chronological age and hormonal changes, but these indicators can suffer interference. Aiming at a more accurate determination of development and growth peaks, for a better diagnosis and treatment plan, several methods have been developed to determine skeletal age and dental age, these being the assessment of carpal maturation, the morphology of the cervical vertebrae, bone fusion of the spheno-occipital synchondrosis and the median palatal suture, as well as the stages of dental calcification. The evaluation of hand and wrist radiographs is the gold standard for predicting skeletal age, and its correlation with other methods is already evident. Therefore, it is possible to use the assessment of cervical vertebrae and dental ages by Nolla and Demirjian.

ABSTRACT

The purpose of this paper is to study the pattern of change which are age associated,so as to provide a new method of age estimation by bone for forensic medicine and anthropology.The middle one third of right ribs were collected from 67 Chinese females living in North China.Decalcified cross section slides were histomorphometrically examined by using an image analyzer.Then the parameters were subjected to multiple stepwise regression analysis to produce an equation:=31 264+0 868X 2+286 693X 4+0 689 X 7-778 874X 8-0 006X 9.The multiple correlation coefficient and standard error of estimate were 0 923 and 4 08,respectively.When the formula was checked by 25 specimens,84% of the estimated ages fall within ?5 years of actual ages,and 100% of the estimated ages fall within ?8 years of actual ages.This showed that female ages could be deter mined by the histomorphometry of ribs.
