Introduction:Determining the age of a person in the absence of documentary evidence of birth is essential for legal and medico-legal purpose. Fishman method of skeletal maturation is widely used for this purpose; however, the reliability of this method for people with all geographic locations is not well-established.Aims and Objectives:In this study, we assessed various stages of carpal and metacarpal bone maturation and tested the reliability of Fishman method of skeletal maturation to estimate the age in South Indian population. We also evaluated the correlation between the chronological age (CA) and predicted age based on the Fishman method of skeletal maturation.Materials and Methods:Digital right hand-wrist radiographs of 330 individuals aged 9-20 years were obtained and the skeletal maturity stage for each subject was determined using Fishman method. The skeletal maturation indicator scores were obtained and analyzed with reference to CA and sex. Data was analyzed using the SPSS software package (version 12, SPSS Inc., Chicago, IL, USA).Results:The study subjects had a tendency toward late maturation with the mean skeletal age (SA) estimated being significantly lowers (P < 0.05) than the mean CA at various skeletal maturity stages. Nevertheless, significant correlation was observed in this study between SA and CA for males (r = 0.82) and females (r = 0.85). Interestingly, female subjects were observed to be advanced in SA compared with males.Conclusion:Fishman method of skeletal maturation can be used as an alternative tool for the assessment of mean age of an individual of unknown CA in South Indian children.
Introduction: Very little attention has been given in orthodontic diagnosis and treatment planning regarding appropriate facial orientation during photographic recordings. Analysis of facial profile using standardized photographs is a valuable tool for orthodontic diagnosis. Materials and Methods: We have worked on a new way to position the patient's head with Frankfort horizontal parallel to the floor by use of a a specially fabricated device. It consists of a vertically adjustable scale attached to metal framework. The shadow of the scale is projected as a horizontal line onto the face by means of a light source. The patient's head is positioned such that the Frankfort horizontal lies along the projected line. Twenty-five (13 males and 12 females) people aged between 15 and 25 years were photographed using the above method with a digital singlelens reflex camera. The photographs were taken again after a 15-day interval using the same protocol and checked for reliability. Results: Statistical analysis was done using paired student t-test and Kappa test. The results showed that there was no statistically significant difference between the mean angles at the initial (76.92 ± 4.77) and 15-day interval (76.72 ± 4.67) in profile view and between the mean angles at the initial (90.88 ± 2.06) and 15-day interval (90.96 ± 1.96) in the frontal view Conclusion: This method allows us to take facial photographs by positioning the patient's head such that the FH plane is parallel to the floor. This method also helped us in standardization of facial photographs when photographs are taken in successive visits.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
