Introduction: Sex determination is a valuable and important factor in the forensic dentistry. Mandible has several useful traits for sex determination. Forensic practitioners study this by two methods: morphological and metrical analyses. Among various methods, the gonial angle may be used to differentiate male and female strongly to express sexual dimorphism. Aim: To analyse the gender determination using gonial angle as panoramic study among south indian population. Materials and Methods: This is a retrospective study conducted among 200 individuals. Gonial angle is a measurement taken by measuring the angle between the 2 tangents from the gonion.As a standard procedure, measurement of right gonial angle and left gonial angle were carried out by Adobe Photoshop and the results were recorded and analysed statistically using SPSS tool. Results: The mean right gonial angle for males is 95.25 and for females is 95.22 The mean left gonial angle for males is 95.39 and for females is 95.15. The significance of the right gonial angle is P=0.874 and significance of the left gonial angle is P= 0.147. The total mean value for right gonial angle was found to be 95.23 and for left gonial angle is 95.27. Therefore, there was no significant difference found between the right and left gonial angle. Conclusion: Within the limitations of the study, there is no statistically significant difference observed between males and females in the gonial angle measurements. The Gonial angle measurements can be used to determine the gender and the growth pattern of the mandible. Measurement of gonial angle has its own surgical importance too in the field of orthodontics and therefore future studies should be carried out using larger samples to get reliable results.

“…Diagnosis of elongated styloid process is confirmed by analysis of radiographs and clinical examination of the patient is considered as an important tool. The experience from our previous studies [12][13][14][15][16][17][18][19][20][21][22] have led us to focus on the current topic [12].…”

Introduction: Styloid process is a slender osseous projection, cylindrical and sharp projection of the temporal bone, located in front of stylomastoid foramen. Styloid process is from Reichert’s cartilage of the second branchial arch, this is a part of the splanchnocranium. This is Connected to the hyoid bone through the Stylohyoid ligament. The morphology of the Styloid process is due to hormonal and genetic changes. Orthopantomography is a radiographic method used to visualise mandibles. It also provides a rotational view of the jaw. The aim of the study is to analyse the elongation of the Styloid process in the South Indian population. Materials and Methods: The study was conducted in dental institutions with convenience sampling. The random orthopantomogram sample was collected from a dental institution. Total number of orthopantomogram involved in the study was 80 (40-males and 40-females) that is used to examine elongation of the Styloid process in the South Indian population. The minimised sampling bias is done by stratification according to age and gender. Statistical Analysis: The data were analysed by using SPSS software. The probability value p< 0.05 is considered as significant and the value p>0.05 was considered as not significant. Results: This study showed various types of Styloid processes in males and females. However we concluded that there is a difference in shape of Styloid processes. The most common type of the Styloid process found in males is pseudo articulated (32.5%) whereas in females the most common type of Styloid process found is uninterrupted (37.5%) Conclusion: From the current study we have concluded that the pseudo articulated Styloid process is more in males whereas uninterrupted is more in females. Only retrospective studies were done so far. Therefore in future studies with live models and larger sample size should be conducted.

“…As a result, we attempted to discover the most common position and size of the mental foramen in adult South Indians in our current study [3]. The experience from our previous studies [4][5][6][7][8][9][10][11][12][13] have led us to focus on the current topic.…”

Background: The mental foramen (MF) is a hole in the body of the mandible that is placed on the antero-lateral side. Between the upper and lower mandibular borders, it can be found. It sends signals to the brain's nerves and blood vessels. Many researches have documented variations in the placement of the MF among different ethnic groups, as well as variations in its forms. It's commonly found beneath the first premolar teeth. The study's goal is to look at where mental foramen are found in the South Indian population. Materials and Methods: A total of 100 distinct OPGs from the South Indian population were used in the investigation. The position of mental foramen for various mandibles was visually examined using OPGs, and the data was tallied and analyzed using SPSS. Results: From the results it is suggested that the maximum frequency for the right side is at location 2 which is in the longitudinal axis of 1st premolar. 14.0% at location 1, 31.6% at location 2, 21.1% at location 3. 17.3% at location 4. 10% at location 5, 6% at location 6. The situation of mental foramen at the axis of 1st premolar was observed to have a high frequency of occurrence in the age group of 26-35. Conclusion: The Mental foramen in study population is mostly found in the longitudinal axis of 1st premolar. The clinical students and surgeons should know the existence of mental foramen at surgical procedures using mandibular premolar and molar regions. Future studies with large sample sizes should be conducted to make the results conclusive.
