A Study On Morphometry Of The Human Mandible In Relation To Sex
Main Article Content
Abstract
Mandible Is The Hardest And Most Durable Bone Of The Skull Exhibiting High Degree Of Sexual Dimorphism. This Characteristic Feature Of Mandible Helps A Sex And Age Determination In Medicolegal Cases. Dimensions And External Features Of The Mandible Are Necessary For The Dental Surgeons In Inferior Alveolar Nerve Anaesthesia And The Otorhinolaryngology Surgeons For Laryngoscopy And Endotracheal Tube Intubation.
In Anthropological Excavations, The Morphometric Features Of The Mandible Help To Identify The Race, Sex, Age And Food Habits Of The Population And Also Help To Understand The Human Evolution.
Objectives:
- To Measure And Document The Metric And Non-Metric Parameters In Dry Human Mandible Of Males And The Non-Metric Parameters, Observed Was Shape Of The Chin And Contour Of The Lower Border Of The Mandible. The Metric Parameters Measured Was Mandibular Length, Gonial (Mandibular) Angle, Condylar Height, Coronoid Height, Minimum Ramus Breadth, Maximum Ramus Breadth And Bigonial Breadth.
- To Analyse The Morphometric Data Of Mandible In Relation To
- To Know Any Statistical Difference In The Morphometric Features Of The Mandible In Relation To
Methods:
100 Adult Human Mandibles. The Non-Metric Parameters Were Observed And Interpreted Based On Their Definitions. The Metric Measurements Were Measured With The Help Of Instruments Mandibulometer And Vernier Calipers In Millimeters Or To The Nearest Of 0.1mm.
Conclusion :
The Bilobate Chin Of Male Mandibles Possess Rocker Bottom Contour Of The Lower Border Of The Mandible With Wider Bigonial Breadth And Acute Gonial Angle. The Pointed Chin Of Female Mandibles Showed Either Rocker Or Straight Contour With Obtuse Gonial Angle And Lesser Bigonial Breadth. The Right Cornoid And Condylar Height Showed Significant Values, But Mandibular Length Was Almost Equal In Both Sexes. The Minimum And Maximum Ramus Breadth Show Significant Difference Among The Gender.
