Evaluation of Intermental Foramina Distance among South Indian Population

Background: The intermental foramina distance varies between ethnicities, according to an OPG (orthopantomogram), which is a form of dental x-ray. The mandibular foramen has a bony canal developed in the mandible at two independent anatomies and its rim is 'v' shaped, that was its common form where the groove separating the anterior and posterior parts is horizontally orientated rim which is an oval shaped rim. The placement of the mandibular foramen varies by ethnicity; the intermental foramina distance is always measured from the mandibles' mid-line. Materials and Methods: The OPGs are collected from the private dental college and hospital in chennai. The location of mental foramen is identified and the intermental foramina distance is calculated by adobe photoshop. The collected data is analysed using SPSS software. Results: The average intermental foramen distance in the south Indian population was 4.93 cm. Males have a 5.14 cm inter mental foramen, whereas females have a 4.76 cm inter mental foramen. With a p value of 0.001, there is a significant difference in the intermental foramina distance between the genders in the south Indian population. Conclusion: Within the restrictions of the study, it may be stated that there is a significant difference in the intermental foramina distance between men and women in the south Indian population, with a p value of 0.001. The dentist's understanding of the intermental foramina difference is critical when performing implants, orthodontic surgery, and periodontal surgery. It aids the dentist in planning the drilling of the lower jaw bone.
