“…Two different approaches to the study of mental foramina are available: evaluation and statistical analysis of panoramic radiographs of a large group of patients and experimental procedures carried out on dry skulls [7]. The studies of Philips et al [3,5], Igbigbi et al [8] and Singh et al [9] used dry human mandibles for detection of mental foramen.…”

Abstract. The identification of the mental foramen is important for both diagnostic and clinical procedures. The knowledge about its accurate location is significant in reducing complications that may occur during surgical and endodontic treatments involving the mental area. The purpose of this study was to determine the position of mental foramen in relation to the radiographic apex of the mandibular second premolar on panoramic radiographs. Two hundred digital panoramic radiographs were analyzed in this study. Horizontal and vertical position of the mental foramen was determined in relation to the two reference lines which passed through the apex of the mandibular second premolar. The possible positions were: mesial below, mesial intersecting, mesial above, intersecting below, centered, intersecting above, distal below, distal intersecting and distal above. Fifty percent of the panoramic radiographs showed that the mental foramen position was mesial and below the radiographic apex of the second premolar. Mesial and intersecting position was observed in 21% of the radiographs, centered in 13%, intersecting and below in 8%, distal and below in 6%, while 2% of the radiographs showed distal and intersecting position of the mental foramen. No statistically significant differences in the position and the symmetry of the mental foramen were observed in relation to the gender and the side of the mandible. The most common position of the mental foramen was mesial and below the radiographic apex of the mandibular second premolar. For an accurate assessment of the location of the mental foramen, a preoperative radiological study with a panoramic radiograph is necessary.

“…Accessory foramina was also investigated and when multiple foramina were present, the uppermost one that is closest to the inferior dental canal was recorded as the main foramen (Yosue & Brooks, 1989a).…”

“…The vertical location of mental foramen and other characteristics such as accessory foramina and appearance have been studied in different populations by clinical radiographs (Yosue & Brooks, 1989a, 1989bPhillips et al, 1992aPhillips et al, , 1992bal-Khateeb et al, 1994;Al Jasser & Nwoku, 1996;Olasoji et al, 2004;Laster et al, 2005;AlKhateeb et al, 2007) or collections of dried skulls (Phillips et al, 1992a(Phillips et al, , 1992bMbajiorgu et al, 1998;Sawyer et al, 1998;Ngeow & Yuzawati, 2003;Souaga et al, 2004;Agthong et al, 2005;Igbigbi & Lebona, 2005). Since the Gulf war in 1991, a dramatic increase of Iraqi population in Jordan, especially in the capital city Amman, has been noticed by the Jordanian immigration authority which reported more than half million of them entering and leaving Jordan since 1990 up to March 2007.…”

The Mental Foramen II: Radiographic Study of the Superior-Inferior Position, Appearance and Accessory Foramina in Iraqi Population

SUMMARY:Accurate information regarding the vertical location and appearance of the mental foramen, and the presence of accessory foramina, can have clinical significance, such as reducing complications that may occur during many oral surgical procedures involving the mental area. Geographic variations were reported in these variables. The aim was to evaluate the above-mentioned variables in an Iraqi sample. Five hundred eighteen panoramic radiographs of a random Iraqi sample (257 males, 261 females, average age= 46.5 years) were evaluated with regard to the above-mentioned variables, as well as the symmetry of the foramen regarding these variables. The area below the apices of mandibular premolars, and the continuous type were the most frequent vertical location and appearance of the mental foramen, respectively. Age advancement was found to be associated with an increase in the frequency of more inferior positioning and continuous appearance. The vertical position and appearance were asymmetrical in 16.2 % and 20.1 % of cases, respectively. Symmetry in the vertical location was statistically significant between sexes (P= 0.035), and young and old ages (P= 0.000). Symmetry in the appearance was found statistically significant (P= 0.025) only between the two age groups. Accessory foramina were recorded in 7.3 % of cases. The most common vertical location and appearance of the mental foramen on panoramic radiographs in this group are below the apices of mandibular premolars, and continuous type, respectively. This is in consistence with the findings of previous studies on other populations. The mental foramen usually has symmetrical vertical location and appearance. Accessory foramina are recorded in a percentage lower than that recently reported in some regional countries.

“…[21]Panoramic radiographs usually are limited due to horizontal overlap of teeth [22] distortion and magnification in orthopantomogram techniques cannot be eliminated, in addition, as the bone density increases, the foramen becomes more difficult to identify and may not be seen clearly. CT has been the first option for diagnosis, surgical planning, and treatment of osseous trauma injuries due to its high specificity and sensitivity.…”
