Location and Dimensions of the Mental Foramen: A Radiographic Analysis by Using Cone-beam Computed Tomography

Treatment of mental nerve paraesthesia caused by the endodontic infection of lower second premolar: A case report

“…Foramen mentalenin değerlendirildiği çalışmada, Von arx ve ark. 20 foramen mentale ve komşu kökler arasındaki mesafeyi ortalama 5 mm olarak saptamışlardır. Ancak 3 vakada komşu köklerle arasındaki mesafe 1 mm'den daha yakın bulunmuştur.…”

Morphometric Evaluation of the Mental Foramen Using Cone Beam Computed Tomography in Different Facial Types.

“…The sample size was based in previous studies about this subject and published recently [7,[18][19] Inclusion criteria in any of the three groups were as follows: both genres should be represented equally in the total sample, tomographic viewsshould be obtained only from subjects presenting exclusively with permanent dentition, subjects should not have history of orthodontic treatment, tomographic views should not present artifacts and the right and left mental foramens should be evaluated. Exclusion criteria were the following: patients with a history of orthodontic treatment before initial evaluation; presence of local pathology and/or systemic disease precluding tomographic assessment of the mental foramen; inaccurate tomographic images not allowing proper classification of the facial type, subjects reporting presence of a pathologic condition or syndrome and those participating simultaneously in another study, for instance, those participating in a -post-surgical follow up‖ investigation.…”

“…The inferior alveolar nerve bundle enters the lower jawthrough the mandibular foramen, passes along the mandibular canal and exits from the mental foramen as the mental nerve on the body of the mandible above the tubercleof the chin [3] .Determining the precise location of the mental foramen is a key factor when considering placing dental implants or when surgical proceduresare planned in the foramenregion [4] . The precise location of such foramen is also important in some dental specialties including Operative Dentistry, Periodontics, Endodontics and OrthognathicSurgery, whenever a local anesthesia procedure is to be carried out [5][6][7][8] . In adults, the mental foramen islocated on average between 13mm and 15mm above the inferior mandibular border, but in adults presenting with bone resorption, the foramen is located closer to the alveolar crest and sometimes over it [9] .One problem in determining the precise location of the mental foramen is that such a structure cannot be neither visualized nor palpated and thus, more advanced visualization techniques DOI: 10.9790/0853-1606037885 www.iosrjournals.org 79 | Page have to be used.…”

Evaluation of Mental Foramen in U. P. Population- A CBCT Study

“…Chances of injury rises further if mental foramen is not properly identified and protected [1]. Possibility of these insults further increases with variable anatomy of the mandible in position, course of neurovascular bundles passing through mandibular canal and type of emergence through mental foramen [2]. Variation in its location and accessory foramen sometimes leads to misdiagnosis of some pathology.…”

“…Mental nerve and associated blood vessels pass through this foramen. Previously researchers also showed keen interest in finding the anatomical variation of mental foramen but this issue particularly gain importance due to advanced dental rehabilitation surgeries and also due to more accurate three dimensional diagnostic images (CBCT images) [2][3][4]. Implant placement is one of those dental rehabilitation procedures whose prognosis needs precise knowledge of anatomical variations [5].…”
