Morphometric Studies of Supraorbital Foramen, Infraorbital Foramen and Mental Foramen in a Thai Population Related with Nerve Blocks

The aim of this study was to the anatomical landmarks and variations supraorbital, infraorbital, mental foramina. One hundred sixty Thai dry skulls were randomly selected from Forensic Osteology Research Center. distances parameters measured by using Vernier caliper. supraorbital foramen could be found in a notch form 13.8 %, single accounted for 82.5 with an accessory represented 3.8 %. Single infraorbital 90.0 10.0 observed 96.6 frequency determined 3.4%. majority foramina (48.0 %) detected above second premolar area. 19.0 % seen region between first premolar, 22.8 located molar. is anatomically positioned molar (10.2 %).
