Study Of Mandibular Ramus As Predictor Of Sex

Background: Methods based on measurements and morphometry are accurate and can be used in determinationof sex. Even the bony remains like mandibular ramus can be used to predict the sex of the individual which willbe of help for forensic experts. Morphometry of mandibular ramus will also be of importance for anthropologists,anatomists and prosthetists.Materials and Methods: Coronoid height, maximum ramus breadth, minimum ramus breadth and maximumramus height was measured in 200 adult cadavers.Results: The coronoid height varied from 42.02 mm to 68.46 mm in males and it varied from 40.08 mm to 66.76mm in females. The maximum ramus breadth in male mandible varied from 28.84 mm to 42.28 mm and infemales it varied from 27.44 mm to 41.42 mm. The minimum ramus breadth in males varied from 21.92 mm to36.80 mm, in females it varied from 17 mm to 34.26 mm. The maximum ramus height in males varied from 47.76mm to 68.64 mm and in females it varied from 42.56 mm to 69.56 mm.Conclusion: All the parameters measured were higher in males than females. Comparison studies revealed thatthe South Indian parameters were lesser than Thais, Croatians and Africans.

Determination Of Gender Using Condylar Height And Coronoid Height – An Orthopantomographic Study

BACKGROUND: Identification of gender is important in forensic science and anthropology.When entire skull is not available for analysis, mandible may play a vital role in sex determination as it is the strongest bone that resists damage and disintegration. Aims and Objectives: To determine the efficacy of condylar height and coronoid height of mandible for sex determination using orthopantomographs and to compare and determine the most reliable parameter for sex determination. Materials and methods: This study was conducted using digital panoramic images of 100 each in both genders. The images captured were viewed on Kodak software and were subjected to measure the condylar and coronoid heights both on left and right side using Kodak dental imaging software. The data was entered into microsoft excel sheet and statistical analysis was done. Results: Descriptive statistics for condylar and coronoid heights on the right and left sides of mandible in both males and females were analyzed. A statistical significance of P < 0.001 has been demonstrated for all the variables. All variables showed increased measurements in males than in females. The accuracy of sex determination forcondylar height is 82.5% on right side and 78% on left side and for coronoid height it is 74% on right side and 73% on left side. Conclusion: The parameters such as condylar height and coronoid height using orthopantomographs are reliable in gender determination and the condylar height of the right side is the best parameter in gender determination.
