OBJECTIVE This study was aimed to evaluate the dental age in Saudi children from panoramic radiographs using the Demirjian method to estimate their chronological age. MATERIALS AND METHODS This retrospective cross-sectional study consisted of 1902 panoramic radiographs of 955 boys and 947 girls between the ages of 3-17 years. All children were placed in the age group closest to their chronolo...

The study was designed to investigate the accuracy and precision of three different methods for estimation of chronological age (Liliequist and Lundberg, 1971; Demirjian ci' al., 1973 and Gustafson and Koch, 1974), based on tooth formation. Accuracy test. For each method, the mean difference and degree of linear correlation between estimated and true chronological age was determined in 300 3.5-...

The Demirjian methods to determine dental age are based on analysis of orthopantograms. The dental age estimation is based on establishing the tooth development stages. The purpose of this study was to assess the accuracy of estimation of dental age by Demirjian in the use of all of his four methods. 505 Czech healthy boys and girls aged 3 to 18 years were examined radiographically at the Depar...

OBJECTIVES The purpose of this study was to test the applicability of the Demirjian method and revised versions for estimating chronological age (CA) from dental age (DA) in a sample of children. STUDY DESIGN A sample of 252 individuals of known age (4 to 14 yrs), sex (males: 125, females: 127), and ethnicity (Saudi) was collected. Each individual was aged using the original Demirjian method ...

The age of the individual can be assessed as skeletal age, morphological age, secondary sex character age and dental age and these may be applied singly or in conjunction to assess the degree of physical maturity of a child. The determination of physiological age is based on the various degree of maturation of the different tissue systems. Dental age is one of the important factor taken into ac...

BACKGROUND Third molar development is the only available tool for estimating the age of individuals after puberty. Since this tooth has very high interethnic variability, formulas calculated to estimate the age from its development stages cannot be generalized to other populations and should be adjusted for each region. Therefore, this study was conducted to evaluate this method in a sample of ...

BACKGROUND AND AIM: This study was designed to assess the correlation between chronological age and modified Demirjian estimated dental age.METHODS: Panoramic radiographs of 183 Patients between 13.5 and 20.5 years old were assessed for the developmental stage of lower right third molars. Student’s t-test was used to measure the same hypothesis of the chronological age and estimated modified De...
