OBJECTIVE The aim of this study was to determine the differences between the skeletal ages estimated by TW2 and TW3 methods through their RUS and Carpal systems. MATERIAL AND METHODS A sample of two hundred and forty hand and wrist radiographs of male and female Brazilian children aged 84-199 months was evaluated by five observers. The Dunnet test was performed for statistical analysis. RES...

BACKGROUND A method for assessing dental maturity in different populations was first developed in 1973 by Demirjian and has been widely used and accepted since then. While the accuracy for evaluating dental age using Demirjian's method compared to children's chronological age has been extensively studied in recent years, the results currently available remain controversial and ambiguous. METH...

An aim of this paper was to discover whether athletes of different pubertal status, chronological age, and gender reported distinct coping strategies in response to stress during a competitive event in their sport. A secondary aim was to examine pubertal status group, chronological age, and gender differences in coping effectiveness. Participants were adolescent athletes (n = 527), classified a...

What is ageing? One definition is simultaneous degradation of multiple organ systems. Can an individual be said to be “old” or “young” for their (chronological) age in a scientifically meaningful way? We investigate these questions statistically using ageing related phenotypes measured on the 12,000 female twins in the Twins UK study [4]. We propose a simple linear model of ageing, which allows...

OBJECTIVE To our knowledge, only two controversial articles have reported the study of bone age at diagnosis in diabetic children. The aim of this study was to compare chronological age with bone age and to evaluate the impact of A1C on bone age in children at diagnosis of type 1 diabetes. RESEARCH DESIGN AND METHODS In 496 diabetic children, height was measured at diagnosis and height SD sco...

BACKGROUND chronological age is widely used as a marker of frailty in clinical practice. However there can be wide variation in frailty between individuals of a similar age. Grip strength is a powerful predictor of disability, morbidity and mortality which has been used in a number of frailty scores but not as a single marker of frailty. OBJECTIVE to investigate the potential of grip strength...

OBJECTIVE The aim of this study was to establish reference data on third molar morphology/development for age estimation in Western Saudi adolescents, between ages 14 and 23 years of old. MATERIALS AND METHODS The orthopantomograms of 130 individuals (males and females), were examined, and the stage of third molar development were evaluated. RESULTS Mean ages, standard deviations, and perce...

The aim of our study was to determine the pattern of female reproductive organ growth in Indian girls from birth to 18 years of age and to correlate the uterine length, mean ovarian volume (MOV) and Fundo Cervical Ratio (FCR) with chronological age, bone age and pubertal breast staging. A cross sectional study was performed on 218 girls from birth to 18 years of age. Height, weight, stage of pu...
