| dc.description.abstract | Age estimation is a part of forensic science that plays an important role in the
identification process in every aspect of life. Age estimation using teeth can be
analyzed using radiographyc methods that can be done based on age groupings
(7,8,9,10,11 dan 12 years). There are several age estimation methods using
radiography, including the Demirjian method and the Willem method. The purpose of
this study was to determine the difference between chronological age and dental age
based on the Demirjian and Willem method using panoramic radiographs age 7-12
years and the more accurate method used between the two. This was an observational
analytic study with cross sectional design. The study sample was 60 panoramic
photographs of 30 male and 30 female patients aged 7-12 years obtained from the
medical records of patients who performed orthodontic treatment at RSGM USU.
Estimation of dental age can be seen by assessing the stage of tooth calcification
according to the Demirjian and Willem method. The result of the study obtained and
average chronological age of 9.78 +1.48 years, dental age according of the Demirjian
method 9.89+1.45 years and according to the Willem 9.51+1.41 years. There was no
significant difference between chronological age and dental age in males and females
in each age group of 7-12 years according to the Demirjian method. The Willem
method, for males in the age group of 7, 8, 9, 10, 12 years and females in the age group
of 7-11 years, there is no significant difference. The Demirjian method overestimates
age by 0.11 years, while the Willem method underestimates age by -0.27 years. The
conclusion of this study is that the Demirjian method is more accurate than the Willem
method. | en_US |
