INTRODUCTION : As age and stature are dependent in the inquiry level of dimorphism, body remnants, and sex reliably plays a significant role, sex identification is a preliminary phase in forensic examination.. Panoramic radiographs, or orthopantomographs, have a wide range of clinical radiological applications in dentistry.
AIM : The aim of the study is to identify sexual dimorphism of linear measurements of mandibular bone using digital orthopantomographs in south indian population
MATERIALS AND METHODS: Digital panoramic radiography were used in a study.The study was done in the south indian population on 50 radiographs in both the genders. Panoramic radiographs with intact dentition were included and that with fracture or deformation were excluded.  PMI and MCW are radio morphometric methods. PMI is calculated by measuring the distance between the inferior margins of the mandible and the mental foramen. MCW is calculated by measuring the distance between two parallel lines at the mental foramen's limit. The measurement was carried out using adobe photoshop. Statistical analysis using SPSS was done to determine the gender from the linear measurements.
RESULT: Linear measurements for Mandibular Cortical Width (MCW) and Panoramic Mandibular Index(PMI) were taken. The p value for MCW left is 0.479 which is statistically not significant and p value for MCW right is 0.014 which is statistically significant. The p value for PMI left and right is 0.419  and 0.457 respectively which is statistically not significant between gender
CONCLUSION: The study was done on both the side of the mandible and thus the linear measurement of mandibular bone on digital orthopantamographs is done on the south indian population. From the study it is concluded that PMI can be more preferably used for the measurements and the identification.

Background: In accordance of forensic dentistry, every palatal rugae has a remarkable distinct pattern in every human, it can be applied as an identification tool.
Objective: The objective of the present study was to investigate palatal rugae patterns in dentulous and edentulous patients and evaluate the reliability of these patterns in human identification. Methodology: The study group was equally divided into 30 dentulous and 30 edentulous patients, respectively. A duly filled and signed consent form was attained from each participant. Alginate impression material is used for primary impressions in a perforated tray and dental stone (Type-3 Gypsum products) was used to develop a cast. The number, length and shape were recorded after analysing the rugae patterns. Statistical calculation done by using SPSS system. Results: The mean of the total number of rugae more in dentulous (7095 ± 1.393) than edentulous (5.99 ± 1.001) participant. Dentulous subjects shows more curved rugae patterns (2.98 ± 1.321), primary rugae (6.86 ± 1.287) and forwarded rugae (3.84 ± 1.801) while more straight rugae patterns (3.15 ± 1.44) and perpendicular rugae (2.64 ± 1.425) found in edentulous subjects. Conclusion: This study concludes that there is statistically significant variation in dentulous and edentulous participant in term of shape, number, size and direction.
