“…Our findings were similar to the study of Philip [46] and Robbins [41], who also observed non-significant bilateral asymmetry on the footprints of South Indian and US population, respectively. Our findings are also supported by Rao and Kotian [40]; according to them, difference between the left and right footprints in the same individual may be explained on the basis of the "dominant foot." A dominant foot means that the foot which always supports the body to a higher extent while an individual is in standing or in walking condition.…”

Introduction: Personal identification is preliminary concern of medico-legal and forensic investigation. There are various methods including Anthropometry, Fingerprints, foot imprint, bite mark, lip print, ear print by the help of which personal identification can be performed. In India, the bare foot imprints are frequently recovered at the crime scene and stature of a person can be estimated using foot imprint method, so analysis of bare foot imprints are often a necessity for forensic investigation. Materials and Methods: In this study, we made an attempt to reconstruct the stature using foot imprints (footprint and foot outline) method. The 200 samples of male and female age ranges from 18 to 30 years were collected from urban area of Bilaspur, Chhattisgarh, India. Footprint and outline methods were employed in this study, to correlate the size (length) of foot-imprints with the stature (height) A Ad dd dr re es ss s f fo or r c co or rr re es sp po on nd de en nc ce e: :

RESUMENEl propósito de este estudio fue poner a prueba la sensibilidad y especificidad del Índice Canino Mandibular en una población estudiantil joven de la ciudad del Cusco en el año 2017. Se realizó un estudio de validación y fiabilidad en 164 estudiantes universitarios, con edades comprendidas entre 15 y 25 años, a quienes se les midió el ancho mesiodistal de los caninos inferiores y la distancia intercanina, con cuyos datos se calculó el ICM, para luego establecer la sensibilidad y especificidad en la predicción del sexo, teniendo como valor de corte de ICM lo establecido por Rao et al. (3) Al aplicar el ICM a la población joven se obtuvo una sensibilidad del 73,7% y una especificidad del 79,3% para la estimación del sexo. En la prueba ROC el Índice cuenta con una valides y confiabilidad del 74,5%. Se concluye que el ICM aplicado a una población joven de la ciudad del Cusco tuvo una muy buena sensibilidad y especificidad para la determinación del sexo. El ICM es una prueba confiable al momento de determinar el sexo. ABSTRACTIThe purpose of this study was to test the sensitivity and specificity of the Canine Mandibular Index in a young student population of the city of Cusco in 2017. A validation and reliability study was carried out on 164 university students aged 15 and 25 years, who were measured the mesiodistal width of the lower canines and the intercanine distance, with whose data the ICM was calculated, and then to establish the sensitivity and specificity in the prediction of sex, having as cut value of ICM established by Rao et al. (3) When ICM was applied to the young population, a sensitivity of 73.7% and a specificity of 79.3% were obtained for the estimation of sex. In the ROC test, the Index has a validity and reliability of 74.5%. It is concluded that ICM applied to a young population of the city of Cusco had a very good sensitivity and specificity for the determination of sex. The ICM is a reliable test when determining the sex.

“…The maxillary cuspids also show sexual differences with root lengths being on the average 3 mm longer in males. 12 A famous study by Rao et al 13 used mandibular canine index to determine sex. Dental calculus is used for determination of sex by the PCR method using primers, which recognize DYZ3 region of Y-chromosome and DXZ1 of X-chromosome.…”
