Comparative evaluation of morphometric analysis on infra orbital foramen in south indian population-an in vitro study

Abstract

Introduction: Effective pain control in dentistry is achieved by local anaesthetic techniques. To achieve it exact morphometric location of the foramen is essemtial. Aim: Aim of this study is to do morphometric analysis of infra orbital foramen in south Indian population Materials and Methods: 96 human dry skull where examined from the department of Anatomy, various dental and medical colleges in Chennai, Tamil Nadu using digital vernier calliper and a survey sheet was used to make a note of the data. Results: The average distance on left side in females was 13.46 ± 1.99 mm and average perpendicular distance between infra orbital foramen and the line joining canine eminence and base of the orbit on right side in females is 11.39 ± 2.73 mm. The average distance on left side in males was 13.36 ± 2.16 mm and average perpendicular distance between infra orbital foramen and the line joining canine eminence and base of the orbit on right side in males is 11.27 ± 2.05 mm. This study also infers that the location of infraorbital foramen is independent of gender but dependent on the side it is located this is signified by the p value. The p[<0.05] value on left side and p [>0.05] value on right side. Conclusion: The average location on left side is more than the right side. Hence when giving block anesthesia one should be well aware of the location as there are many important structures around infraorbital foramen.
