Abstract

Background: Sex estimation is the first step in identifying bodies following disasters or accidents. Craniometric analysis of lateral cephalograms can be used in the process. Among the measurements that can be used are the length of cranial base, determined by Basion–Nasion (Ba-N) length, and the total face height, determined by the Nasion–Menton (N-M) length, which can highlight significant differences between men and women. Purpose: This study aimed to determine the differences in length of cranial base and total face height measurements between men and women and to demonstrate how these two measurements can be used for sex estimation in the Indonesian population. Methods: This cross-sectional study employed a patient database from the dental hospital of Universitas Gadjah Mada. The study sample consisted of 116 cephalograms taken of 58 men and 58 women aged 20–40 years. The linear measurements were taken using EzDent-I Vatech software. Results: The mean cranial base length measurements in the men and women groups were 103.83 ± 4.37 and 96.01 ± 3.80 mm, respectively, whereas the total face height measurements were 121.03 ± 7.26 and 111.23 ± 5.09 mm, respectively. The Mann–Whitney U-Test revealed a significant difference (p < 0.05) between the groups. Logistic regression showed that the two measurements can be used to form an equation for sex estimation with an accuracy of 88.8%. Conclusion: Length of cranial base (Ba-N) and total face height (N-M) measurements from lateral cephalograms can accurately be used for sex estimation. Further research among specific populations is required to develop accurate methods for sex estimation employing morphometric examination on radiographs.

Abstract

Background: The identification of victims is becoming an integral part of forensic investigations. The initial step in forensic identification is sex determination. Using panoramic radiographs, it is possible to determine the height of the mandibular ramus and the distance to the mental foramen for the purpose of sex determination. This study aimed to compare the mandible ramus height and mental foramen distance on panoramic radiographs between men and women.Method: This study utilized 70 panoramic radiographs of complete mandibular dentition from 35 men and 35 women aged 20 to 40 years. The samples were obtained from Dental Hospital of Universitas Gadjah Mada.Result: The average height of mandible ramus in male and female groups were 58.39±2.25 mm and 53.14±2.66 mm, respectively. The distance of the mental foramen was 12.68±1.63 mm in the male group and 10.83±1.23 mm in the female group. The Independent Sample t-test revealed that the p value for the difference between men and women in ramus height and mental foramen distance was 0.000 (p<0.05).Conclusion: Based on the result of this study, both the height of the mandible ramus and the distance of mental foramen on a panoramic radiograph differ significantly between males and females.

Abstract

An experiment to investigate the influence of synthetic dye contrast agent in photoacoustic imaging of biological tissue was conducted in this study. This study uses a simple phocoacoustic imaging system consists of three main components, i.e., a diode laser, condenser microphone, and a custom-build X-Y stage. Characterization was performed on the main components of the system to obtain the appropriate settings on imaging the biological tissue in this study. The results of the optimal frequency and duty cycle for laser modulation in this study were 19000 Hz and duty cyle of 40%, respectively. The addition of a contrast agent aims to improve the quality of the image by comparing the sample with methylene blue contrast agent, the sample with methyl red and the sample without contrast agent. The increases of acoustic intensity level is in proportion with the contrast agent concentration. The difference in the photoacoustic images reveal that the sample with methylene blue contrast agent has the highest acoustic intensity level compared to both sample with methyl red contrast agent and the sample without contrast agent. Therefore, this research proves that a photoacoustic imaging system can be developed to image biological tissue with a contrast agent and methylene blue has greater potential than methyl red to be used as a contrast agent in photoacoustic imaging.
