ABSTRACT Background and objectives The position of mental foramen varies in different ethnic groups. The position of mental foramen is mainly important for achieving effective mental nerve block to carry out dental surgical procedures in mandible. Deviation in its position can be a cause of complication during local anesthesia or surgical procedures. The position of the mental foramen in South Indian and Northeast Indian population has not been reported. The purpose of the current study was to determine the most common location of the mental foramen (MF) and its bilateral symmetry in selected Indian population. Materials and methods 380 digital panoramic radiographs (DPR) of a randomly selected 2 Ethnic groups of Indian population were studied. Results The common position (59.2%) of the mental foramen was located between the 1st and 2nd premolars (P3) in Northeast Indians and in South Indians the common location (62.8%) was in line with the long axis of the 2nd premolar (P4), which was statistically significant in both Populations. Conclusion A bilateral symmetry was observed in the location of mental foramina, either mesial to or in line with the long axis of the 2nd premolar, which is consistent with the observations of similar studies in various ethnic or racial groups. In our study a statistically significant association between the 2 ethnic groups and the position of mental foramen exists. Therefore the position of mental foramen may be specific to racial groups facilitating accurate landmark for mental nerve block depending on the ethnic group. Further, studies are required with larger sample for better understanding of mental foramen location in different ethnic groups.

Abstract Introduction and aim: Mandible usually has a bilateral oval or circular mental foramen [MF] situated on the anterolateral aspect of the body of mandible. Variations of the MF are often encountered ranging from difference in incidence, shape, size, position and supernumerary [accessory MF] to even complete absence. So, the aim of the present study was to evaluate the incidence and the anatomical features of the mental foramen and the accessory mental foramen. Materials & method: 61 dry human mandibles of unknown sex were examined. Size and distance of mental foramen and accessory mental foramen from symphysis menti [Mandibular midline], inferior border of the mandible, posterior border of ramus and superior border of body of mandible were measured using vernier calliper and statistically analyzed by mean and standard deviation. Results: Bilateral mental foramina [MF] were present in all 61 [100%] mandibles. Out of 122 mental foramina [MF], 86 [70.5%] were round and 36 [29.5%] were oval in shape. Approximately half [47.54%] of MF were present below the apex of 2nd premolar tooth. MF was located approximately half way between alveolar crest and mandibular body. Bilateral AMF were present in 1.64% mandibles. All 5 AMFs were round in shape. AMF was separated from MF by a median distance of 2mm. Conclusion: The knowledge about incidence and variability in position of mental foramen and accessory mental foramen is important in order to avoid nerve damage in connection with surgical procedure and to achieve complete effect of anaesthesia after mental nerve block

Objective: The anatomy of mental foramen (MF) is a noteworthy landmark during any surgical procedures in the inter-foraminal region. Thus, the study aims at evaluating the location of MF and the emergence pattern of MN in three status of dentition in Saudi Arabian population. Material and Methods: In a prospective study, we have analyzed 240 cone beam computed tomography (CBCT) for the location of MF and the emergence pattern of MN. The study comprising three groups, namely dentulous, partially edentulous and edentulous, each having eighty CBCT scans. We presented the data in percentages. The chisquare and McNemar’s test were used for testing association and pair-wise analysis, respectively. Results: The most common location of MF was below the apex of the second premolar irrespective of dentition status, with 54.2% in right and 60% in the left side of the jaw. Among the dentition status, left side of the mandible has shown significant variation for the location of MF, whereas gender and age showed variation in the right side. Anterior loop (AL) (Type-III) the emergence pattern of MN was the highest in all dentition status, with 51.7% in right and 53.8% on the left side. The variation in the emergence pattern of MN in terms of gender and side of the jaw was statistically significant. Conclusion: In the Saudi Arabian population, the apex of second premolar and type III/AL was the most prevalent location of MF and the emergence pattern of MN, respectively.

Abstract Background and aim : Mental foramen is an oval or circular opening present on the anterior surface of mandible through which the mental nerve and vessels exit It forms an intportant landmark for human mandible for both invasive and noninvasive procedures. Its position vary according to the age and race. The aim of the study is to provide data on morphology and morphometry of mental foramen. Materials and Methods : The present study was done on ninety dried adult human mandibles of unknown age and sex. Incidences and shapes of the mental and accessory mental foramen were observed. Size and the distances from the various landmarks were noted with the help of digital Vernier calipers. Results: Mental forantina were found bilaterally in all (100%) the mandibles. Accessory mental foramina were found in five mandibles (5.5%) on right side and three mandibles (3.3%) on left side. Shape of the mental foramina was predominantly rounded. Average size of mental and accessory mental foramina was 2.56 mm and 1 mm respectively. The position of the mental foramina below the apex of second premolar , between the first and second premolar and between the second premolar and first molar and below the apex of first premolar tooth were 64.4%, 21.1%, 8.8% and 5.5% respectively. The average distance of the accessory mental forantina from the mental foramen was 0.66 mm and average location was below the first molar tooth. Conclusion: All these findings can supplement useful data for population diversities and can help the surgeons, anatomists, orthodontists and paleoanthropologists to carry out their procedures successfully.

Objectives: The location of mental foramen (MF) is significant in many surgical and nonsurgical procedures related to the mandible to avoid the injury of the mental nerve. The location of mental foramen is considered variable in different populations and even in different groups of population. We used CBCT to locate the position of the mental foramen. As high-resolution three-dimensional images of CBCT reveal anatomic structures more clearly, it improves mental foramen detection, offering advantages over two-dimensional radiological images. Study Design: Cross-sectional Descriptive study. Setting: Department of Oral & Maxillofacial Surgery, University College of Medicine & Dentistry, The University of Lahore. Period: July 2017 to Dec 2019. Material & Methods: A sample of 230 CBCT scans was obtained from the data already available in the department of Oral & Maxillofacial Surgery. The horizontal position of MF was analyzed utilizing 3D images of CBCT at 6 positions concerning the long axis of mandibular premolars and molars. Results: Ninety-six (41.7%) mental foramen were located at position 3, i.e., between the first and second premolars. Moreover, this was the most common location of the mental foramen. Followed by position 4 (in line with the long axis of the second premolar) 90(39.1%). No statistically significant relationship between the gender of the patient and the location of the mental foramen was seen. Conclusion: The location of mental foramen is variable; care should be taken in performing procedures in the area of the mental foramen to avoid iatrogenic injury of the mental nerve. Our results are different from previous studies conducted in the Pakistani population.
