Biometrics of the Hand's Middle Finger to Determine Stature in Chilean University Students / Biometría del Dedo Medio de la Mano para Determinar Estatura en Estudiantes Universitarios Chilenos

SUMMARY: Biometrics and forensic osteology play a significant role in human identification, as the morphological uniqueness of every individual enables the differentiation and recognition of skeletal remains. Through meticulous analysis of human remains, it is possible to determine key demographic attributes such as stature, a significant parameter in the forensic identification process. This information is of practical relevance for the identification of individuals in contexts such as disasters, vehicular accidents, terrorist attacks, armed conflicts, and forensic investigations. The objective of this study was to determine the correlation between the hand's middle finger length and stature in a group of Chilean students. A total of 211 students of both sexes from La Araucanía region, Chile, participated in the study. After obtaining informed consent to participate voluntarily in the study, each individual underwent a general anthropometric examination, followed by a specific assessment of the length of the middle finger (MFL) of both hands. The results of the multiple linear regression analysis indicated a significant prediction of stature using the length of the right (R-MFL) and left (L-MFL) middle fingers, F (2, 207) = 79.80, p < 0.001. The equations for estimating stature based on the length of the middle fingers are as follows: for R-MFL, Stature = 91.265 + (8.092 x R-MFL), and for L-MFL, Stature = 83.967 + (8.889 x L-MF). Based on these results, it was found that the length of the middle finger of both hands is predictive of stature.

La biometría y la osteología forense desempeñan un papel relevante en la identificación humana, dado que la singularidad morfológica de cada individuo permite la diferenciación y reconocimiento de restos óseos. Mediante el análisis meticuloso de los restos humanos, es posible determinar atributos demográficos clave como la estatura, un parámetro significativo en el proceso de identificación forense. Esta información posee relevancia práctica para la identificación de personas en contextos de desastres, accidentes vehiculares, ataques terroristas, conflictos armados e investigaciones forenses. El objetivo de este estudio fue determinar la correlación entre la longitud del dedo medio de la mano con la estatura, en un grupo de estudiantes chilenos. Se evaluaron 211 estudiantes de ambos sexos de la región de La Araucanía, Chile. Tras obtener el consentimiento informado para participar voluntariamente en el estudio, se sometió a cada individuo a un examen antropométrico general, seguido de una evaluación específica de la longitud del dedo medio (MFL) de ambas manos. Los resultados del análisis de las regresiones lineales múltiples indicaron una significativa predicción de estatura utilizando la longitud de los dedos medios derecho (R-MFL) e izquierdo (L-MFL), F (2, 207) = 79.80, p < 0.001. Las ecuaciones para estimar estatura basados en la longitud de los dedos medios son las siguientes: para R-MFL, Stature = 91.265 + (8.092 x R-MFL) y para L-MFL, Stature = 83.967 + (8.889 x L- MF). A partir de estos resultados, se encontró que la longitud del dedo medio de ambos manos es predictora de estatura.

Survey of the Reasons for Dental Extraction in patients of Kashmiri Population

Background: Extraction of teeth is the commonest surgical procedure carried out in the dental surgery setting. The purpose of this survey was to identify the causes of teeth extraction in Kashmiri population. Material & Methods: This study was done on the patients who were referred to Department of Oral and Maxillofacial Surgery Government Dental College Srinagar for tooth extraction for the period of 6 months from February 2019 to July 2019. Total of 3000 patients were included in this study. Results: There were 1680 (56%) extractions in males and 1320 (44%) in females with male?to?female extraction ratio of 1.2:1. In both male and female gender, there were more teeth extractions between the ages of 11 and 30 years. The commonest tooth to be extracted was 1st molar both in upper (27.2%) and lower (30.4%) arch. The commonest reasons for teeth extraction were caries (53.4%; 1602/3000). Conclusions: The result of this study shows that dental caries is the commonest reason for tooth extraction in Kashmiri population. It is hoped that the study will facilitate the development of treatment and preventive procedures relevant to the problems, thus minimizing the loss of teeth and its expected adverse consequences.

Correlation of Human height with dimensions of hand. A study in Young Population of Northern India

Background: Anthropometry has continuously been used in forensic examinations of unknown commingled human remains. Forensic Anthropology is concerned with the building of ante mortem histories of individuals from skeletonized remains The aim and objective is to find out the bilateral and bisexual variations from the percutaneous measurement of length of hand and middle and little fingers of both hands of males to reconstruct the stature.Material & Methods:100 male undergraduate students were taken up for the study. The stature was measured by a stadiometer. The hand length and finger length were measured by the measuring scale and vernier calipers. The prediction of estimation of stature from the length of both hands, middle finger length and little finger length of both hands was determined.Results:The mean height in males is 174.3690±6.18 cm. The mean hand length in males is 19.74±0.87 cm in right hand and 19.65±0.83 cm in left hand. The mean length of right middle finger length is 8.32±0.45 cm and left middle finger length in males is 8.28±0.49 cm. The mean length of right little finger length is 6.38±0.43 cm and left little finger length in males is 6.27±0.52 cm.Conclusions:Positive and statistically significant correlation can be observed among the different variables taken up in the present study. Pearson’s correlation was used which can predict a significant relationship between the height and the length of hand and middle finger of male.
