Detection of the position of the mental foramen in a sample of holly karbala population using plastic T-Bar on panoramic radiography

Abstract EN

Occur study for period from 2012-2013for Knowing the position of mental foramen is very important specially in the recent development in the dental implantology specially in the lower premolars and molars area to choose the proper area for the implant or for surgical procedures in this area during removal of cystic and pathologic swelling or in endodontic surgery in the posterior mandible to avoid the mental nerve injury .

During this study 312 digital panoramic radiographs are examined for the position of the mental foramen in a sample from Holly Kerbela population, from the age of 15-50 years sample was randomly selected and who have the complete dentition or at least who have the mandibular premolars, in a healthy condition ,the results analyzed for both left and right sides of the jaw and for both the symmetrical and unsymmetrical and added to the results .

(174 female and 138 male) the most frequent position of the mantel foramen between the two mandibular pre molars in 148 patients that represent 47.435% of the whole sample followed by 116.5 patients below the2nd premolar which represent 37.339% of the whole sample , below the 1st premolar found in 26.5 patient 8.49% of the whole sample and in 21 patient the mental foramen found distal to the2nd premolar 6.73% of the whole sample.92.94%found symmetrical for the left and right position of the mental foramen the unsymmetrical found in 7.06% of the whole sample.
