ABSTRACT
ABSTRACT

Objectives:

To evaluate the accuracy of Demirjian method in estimating the chronological age of male and female Jordanian children and to establish a new dental age curve if the Demirjian method was not found to be accurate.

Methods:

Orthopantomograms (OPTs) of 1374 Caucasian Jordanian children (684 females and 690 males) aged 4 to16 years were selected and the dental age was determined by Demirjian method. The chronological ages of the children were obtained by subtracting their birthdates from the date of taking the radiograph. The OPTs were obtained from Archives of Dental Teaching Clinics /XXX and other private orthodontic practices in Irbid and Amman.

Results:

Demirjian method overestimated chronological age in female and male subjects aged 4 to 8 years. Afterwards, the method underestimated chronological age in females aged 9-11 years and 14-16 years. In male subjects, chronological age was underestimated in subjects aged 9-12 years and 15-16 years. New the dental age curves for Jordanian females and males were constructed. The constants for the quadratic model for the new curves were (b0=-25.341, b1=17.557, b2=-0.623) for females and (b0=-29.809, b1=17.396, b2=-0.595) for males.

Conclusion:

Demirjian method overestimated the chronological age of Jordanians below the age of 8 years and underestimated the age of Jordanians above 8 years. A new DA standard for Jordanian children was developed and tested for accuracy.
RESUMO
RESUMO

Objetivo:

Avaliar a precisão do método Demirjian na estimativa da idade cronológica de crianças jordanianas do sexo masculino e feminino e estabelecer uma nova curva de idade dentária, se o método Demirjian não for acurado.

Métodos:

Foram selecionados radiografias panorâmicas (OPTs) de 1374 crianças jordanianas caucasianas (684 do sexo feminino e 690 do sexo masculino) com idades entre 4 e 16 anos, e a idade dentária foi determinada pelo método de Demirjian. As idades cronológicas das crianças foram obtidas subtraindo as datas de nascimento a partir da data da realização da radiografia. Os OPTs foram obtidos em Archives of Dental Teaching Clinics / XXX e outras clínicas ortodônticas particulares em Irbid e Amã.

Resultados:

O método Demirjian superestimou a idade cronológica em indivíduos do sexo feminino e masculino com idades entre 4 e 8 anos. Posteriormente, o método subestimou a idade cronológica em mulheres de 9 a 11 anos e 14 a 16 anos. Nos homens, a idade cronológica foi subestimada nos indivíduos de 9 a 12 anos e 15 a 16 anos. Novas curvas de idade dentária para mulheres e homens jordanianos foram construídas. As constantes para o modelo quadrático para as novas curvas foram (b0 = -25.341, b1 = 17.557, b2 = -0.623) para mulheres e (b0 = -29.809, b1 = 17.396, b2 = -0.595) para homens. Conclusão O método Demirjian superestimou a idade cronológica dos jordanianos abaixo de 8 anos e subestimou a idade dos jordanianos acima de 8 anos. Um novo padrão DA para crianças jordanianas foi desenvolvido e testado quanto à precisão.
