“…Constraints to the use of DNA analysis, fingerprints and dental record comparisons occur in situations where mass disasters occur. A useful method of human identification in this circumstance is by identifying the palatal rugae (De Angelis et al, 2012;Buyuk et al, 2017;Basman et al, 2018). Sexual dimorphism has made a significant contribution to rebuilding the identity of victims, and it has played an important role in narrowing lists of missing persons (Adserias-Garriga et al, 2018;Andrade et al, 2019).…”

To investigate the correlation between the anatomical morphology of palatal rugae and sex. The study sample consisted of 120 students studying from Shanxi Medical University, of which 60 were females and 60 were males. The digital model of the palatal rugae was obtained by the 3 Shape TRIOS intraoral scanner. And the shapes of palatal rugae were recorded. Association between palatal rugae shape and sex were tested using Chi-square analysis. And logistic regression analysis (LRA) was carried out to calculate the accuracy of gender prediction using rugae shapes. There was a statistically significant difference between males and females in terms of the distribution of wavy and circular palate rugae. The use of logistic regression analysis obtained a sex predictive value of 65 % when all the rugae shapes were analyzed. Digital images of the palatal rugae morphology contribute to more accurate and convenient for data collection and transformation. It was found that rugae patterns can moderately identify the sex of the specific population when multivariate statistics such as LRA is applied. The palatal rugae morphology can be utilized as an assistant measure for sex identification.

“…Sex determination is needed for estimating age and stature and can cut the number of possible matches in half (Macaluso 2010). Identification of the victim's body corpse in forensic can be performed using varying methods, such as using stages of third molar development (Luthfi et al 2017), using palatal rugae for edentulous corpse (Basman et al 2018;Suhartono et al 2016), using teeth measurement (Silva et al 2016), or using DNA source (Roewer 2019).…”

Background Sex determination can be useful in forensic casework, such as in mass disasters, transportation accidents, and cases of a missing person or sexual assault. The remnants of the body can be traced by DNA of the victim, using samples from various sources such as teeth, oral epithelial tissue, and saliva. Main body The review aimed to describe research in forensic dentistry with DNA source from the oral region and methods of the applied DNA analysis. A search in PubMed, Google Scholar, and Scopus electronic databases from 2009 to 2019 was conducted to include studies according to PRISMA guidelines. Ten studies were eligible for the review. Genetic markers originated from dentin, dental pulp, saliva, or epithelial cells from buccal tissue and prosthesis. The applied DNA analysis methods were PCR, real-time PCR, and nested PCR. Conclusions The published articles mostly showed successful DNA extraction and sex determination, but the rate of success declined as the sample source underwent manipulation to mimic the forensic conditions. Amelogenin, SRY, and DYS14 were reliable indicators for sex determination. Molecular analysis has proved to be efficient and accurate, but the daily forensic practice must select the most appropriate method according to the available body remnants.

To determine whether anterior and posterior tooth crown traits exhibit sexual dimorphism and identify traits characteristic to the Mongoloid race, especially among the Indonesian population. Material and Methods: This study cross-sectional study analyzed 108 dental casts from 36 males and 72 females. The traits analyzed included winging, shoveling, double shoveling, canine mesial ridge, canine distal accessory ridge, hypocone, metaconule, Carabelli's cusp, protostylid, metaconulid, enteconulid, and hypoconulid. All tooth crown traits were scored based on the ASUDAS scoring system. Descriptive statistics were used to calculate the absolute and relative frequencies. The Chi-square tests was used to determine significant differences in anterior and posterior tooth crown traits between males and females. Level of significance was set at 5%. Results: None of the traits showed sexual dimorphism. Moreover, the most common traits among the Mongoloid race were hypocone (94.4%) and shoveling (86.1%). Conclusion: Although none of the traits exhibited sexual dimorphism, most of them had a higher incidence among females than males. Nonetheless, further research including adequate samples and a similar number of females and males, is needed, especially for population studies.
