ABSTRACT
Background: Mental foramen is a key factor in many of the surgical as well as clinical procedures in routine clinical practice.
The variations of mental foramen with respect to position, size and number does significantly alter the clinical implications of various intraoral treatments.
In this light, the present study on the position and morphological variants of mental foramen holds significance.
Aims and Objectives: To study morphological and morphometric analysis of mental foramen in dry human mandibles of South India
Materials and Methods: 50 dried adult Human mandibles of unknown sex with complete dentition and intact alveolar margin were studied
The morphometric analysis was done using vernier calipers
Results: In the present study, the most common position of mental foramen was of type 4 (in line with the 2nd premolar) 62% cases on Right and 66% cases on Left side
The next common position was Type 3(Between the premolars) 24% cases on Right side and 18% cases on the left side
The mean distance between Symphysis menti and anterior margin of mental foramen was 23.4mm and 23.2mm on Right and left side respectively and the mean distance between posterior margin of mental foramen and posterior border of ramus was 62.2 mm and 61.5 mm on Right and left sides respectively
Conclusion: The present study has thrown light on the common position and morphometric variations of mental foramen in a given South Indian population.
This information will be valuable to the dental surgeons for localization of Neurovascular bundle emerging through mental foramen and for delivering local anesthesia effectively for placement of dentures/implants and other invasive procedures
Keywords: Mental foramen, Human mandible, Morphology, Morphometry.
