ABSTRACT
BACKGROUND: The aim of this study was to compare the morphological differences in the mandible between patients with six age groups and to detect the correlation between these parameters on panoramic radiography (PR) and cone-beam computed tomography (CBCT). MATERIALS AND METHODS: A total of 121 subjects (50 males and 71 females) were included in the study and were divided into six age groups (10-19, 20-29, 30-39, 40-49, 50-59, and 60-69) on the basis of the chronological age. CBCT and PR methods were used to record the mandibular measurements for the same 121 patients. Differences between male and female mandibular morphometric measurements, between right and left side measurements, and differences in age subgroups compared by using independent samples t-test, paired samples t-test, and one-way ANOVA test, respectively. P < 0.05 value was considered statistically significant for all analysis. RESULTS: Males mostly have higher mandibular measurement values. There were statistically significant differences between CBCT and PR measurements (p < 0.05). PR mostly showed higher values than CBCT measurements. CONCLUSIONS: Based on the fact that PRs showing significant differences from CBCT in the morphometric measurements made on mandible, it is recommended that forensic doctors and anthropologists consider this information in their age and gender prediction studies.

Humerus is the longest and thickest bone of the upper limb. As a long bone, it has two epiphysis and diaphysis. In this study, we aimed to conduct morphometric measurements belonging to human humerus. This study was conducted on 60 humerus (28 right, 32 left) in collections of Necmettin Erbakan University Meram Medicine Faculty Anatomy Laboratory. Digital calipers, osteometric board and precision scales for humerus bone measurements were used. Measurements were classified as measurements of diaphysis and proximal and distal epiphysis of humerus. Each bone weight was determined. Also nutrient foramen number and localization was determined. In this study, it was determined that mean right humerus length 30.41±1.73 mm, mean left humerus length 30.04±2.39 mm. It was identified that mean right humerus weight was 115.05±28.06 g, mean left humerus weigh twas 111.63±33.34 g. In 9 humerus (15 %), supratrochlear foramen has been observed. 6 of these were oval and 3 of them were round. Nutrient foramen has not been observed in two humerus (3.3 %). Also, medium and weak correlation was identified between many parameters. We believe that the obtained data from this study may be qualities of reference for sex determination from humerus.
El húmero es el hueso más largo y grueso del miembro superior. Como un hueso largo, tiene dos epífisis y una diáfisis. En este estudio, se pretende realizar mediciones morfométricas pertenecientes al húmero humano. Este estudio se realizó en 60 húmeros (28 derechos, 32 izquierdos) en colecciones del Laboratorio de Anatomía de la Facultad de Medicina Meram,Necmettin Erbakan University, Se utilizaron calibradores digitales, tableros osteométricos y escalas de precisión para medir el húmero. Las mediciones se clasificaron como medidas de húmero proximal, corporal y distal. Se determinó el peso de cada hueso. También se determinó el número y la localización de los forámenes nutricios. La longitud media del húmero derecho fue de 30,41 ± 1,73 mm y la del húmero izquierdo fue de 30,04 ± 2,39 mm. El peso medio del húmero derecho fue 115,05 ± 28,06 g y el izquierdo 111,63 ± 33,34 g. En 9 húmeros (15 %), se observó un foramen supratroclear, seis de ellos eran ovales y tres redondos.No se observó foramen nutricio en dos húmeros (3,3 %). Además, se identificó una correlación media y débil entre varios parámetros. Creemos que los datos obtenidos de este estudio pueden ser de referencia para la determinación del sexo de un individio a partir del húmero.
