Abstract

Background : Identification of personal is one of important aspects in forensic odontology, because it is oneof the core aspect of forensic science. The one methode of sex determination is measurement of mandibular.The mandibular is a largest and most powerful facial bone in the skull, which is generally resistant topostmortem damage and an important source for personal identification. Previous studies have studiedgender and age prediction using CBCT reconstructive images in a different picture.The objective of thisstudy is to determine the sex determination of os.mandibular using CBCT anthropometric measurements.Materials and Methods : This study involved twenty subjects (10 male and 10 female) with age groupbetween 20 and 35 years. CBCT scans were performed on all subjects, and the data obtained is reconstructedfor 3D viewing. After getting a 3D CBCT scan, measurements were taken on six parameters.Results : The differential mean of male and female is 1,7 mm (Ramus-L), 2,1 mm (Con-Cor), 6,9 mm(BG-Br), 7,3 mm (BIC-Br), 3,5 mm (BH 1st molar) dan 3,8 mm (BH canine). The collected data wereanalyzed using SPSS statistical with Independent T-Test and Logistic Regression test and also DiscrimantFunction. The results showed that of the six parameters, BG-Br and BIC-Br showed 0,0 (P<0,05) statisticallysignificant differences, with the accuracy of the prediction of gender determination on BIC-Br 70% for maleand 80% for female and the overall BG-Br yield of 80% to both group.Conclusion : Sex determination using mandibular with 3D imaging methods can be used and helps in sexdetermination with 80% accuracy.

Abstract

Analysis sex determination is an important to identification unknown person. CBCT scan can be used to analyzing a dimension in skeletal and for sex estimation when other methods are inconclusive using morphometric aspects, for example through maxillary sinuses can be performed the sex prediction. This study was conducted to estimate the size of the different dimensions of the maxillary sinus to sex determination of an individual by measuring the height, width, length and volume of the maxillary sinus using CBCT in Indonesia. The study of CBCT analysis scan from 20 subject (10 male and 10 female) shows that the potential high score parameter of p value is  0,00 < 0,05 on SI right, MSV right, AP left and MSV Left. It can be used to the prediction of sex determination. Binary logistic regression can be performed 85% from four parameter (SI right, MSV right, AP left and MSV Left) and the result more likely to male. Different result of discriminat function analysis showed the prediction to sex determination use maxillary sinus have percentage 80% to both group. The maxillary sinus measurements are valuable parameters for sex determination in forensic odontology, with a relatively good accuracy rate.

Abstract

Odontology forensic is a branch of forensics science as well as dentistry that handles, examines, and evaluates dental evidence in effort of complying the interest of justice. The ability of dental evidence to be used as an identification tool is very possible as the fact of how durable teeth are. There are several methods to examine the dental evidence in effort to conduct an identification. However, there are circumstances in which histological examination is the only method that can be conducted. This led to the aim of this study. To review histological examination in teeth as sex determination method and to discuss its exclusivity compared to other methods. This literature used journals and textbooks with keywords according to the topic of discussion. Data obtained from different search engines such as Google Scholar, PubMed, Springer and NCBI. A total of 27 journals and 3 textbooks skimmed and narrowed down in to the 12 journals and 1 textbook. Narrowing down the data are necessary as information attained are similar to avoid redundancy. There are two findings that are targeted when it comes to histological examination of the tooth in order to determine one’s sex. They are F bodies and Barr bodies. Both targets appear in sample obtained from the dental pulpal tissue. Further, histological examination as a sex determination method is critical to be develop. Especially in times whereas the other methods are not reliable enough due to limited sample inclusion and cost. It is important to understand histological examination in forensic dentistry.
