SNAuthorsYearResearch findingsRemark

01Saloni, Pradhuman V, P Mahajan, Ankush, Sukhleen Kaur, and Sakshi [16]2020Three parameters out of five mandible ramus variables studied showed statistically () significant differences in genderMandible ramus may be used as an alternate tool in determining gender based on OPG
02Poornima V, Surekha, Venkateswara Rao, G. Deepthi, Naveen S, and Arun Kumar [17]2020Right and left permanent mandible teeth were evaluated in OPG using the Camerier techniqueHigh accuracy is achieved based on the Camerier method applied from an Indian-specific formula
03A Okkesim and S Erhamza [18]2020The average value in min ramus width for males is 31.7 mm and for females is 29 mm. The average projection height value of ramus in females is measured 53.9 mm and in males is 48 mmMandible ramus in CBCT-based model exhibits significant differences in gender determination
04N Vila, R. R. Vilas, and M. J. Carreira [19]2020Gender is evaluated based on DASNet and VVG 16 architectureAccuracy of gender classification is 83% for DASNet and 90% for VGG-16
05Vathsala Patil, Ravindranath, Saumya, Adithya, and Namesh [20]2020Gender determination based on mandible parameters using a logistic regression techniqueIn discriminant analysis, accuracy is 69%, in logistic regression, accuracy is 70%, and ANN shows the highest accuracy of 75%
06J Albernaz, Nathalie A, Ferreira, Vanessa, and Proença [21]2020Teeth cast was used for the experimental procedure. Mesiodistal width of Rt. 1st molar to Lt. 1st molar was measured on each castGender determination was classified with accuracy of 75%
07Dalessandri D, Ingrid Tonni, Laura L, Marco Migliorati, Gaetano I, LVisconti, Stefano B, and C Paganelli [22]2020Reliability and accuracy of OPG versus CBCT for determination of age and genderCBCT was found to be accurate when compared with OPG images in prediction
08Stella A and Thirumalai [23]2020Tooth was divided into different stages starting from A stage to H stageIndividual age assessment using the Demirjian and the Nolla methods
09Ahima Bali Behl [24]2020Measurement of bicondylar breadth (BB), gonial angle measurement, antegonial angle (AGA), ramus height, and ramus breadth (RHRB)Upper and lower breadths of ramus were calculated. Ramus condylar height and coronoid height were measured appropriately
10Vanessa M A, Rocharles, Andreia D’Souza, Casimiro, Andrea, Francisco C, and Deborah Q Eduardo Jr. [25]2019Equations for prediction of age and gender using pulp volumes from upper canine and upper central incisorHigh accuracy can be achieved by using this formula when it is applied to pulp volume
11Wallraff Sarah, Vesal Sulaiman, Syben Christopher, Lutz Rainer, and Maier Andreas [15]2021Unisex and sex-specific approaches based on deep learning methods achieve better results on the test data setMale gender is slightly estimated younger than female gender
