“…Further, when a second midline LF is identi ed, it is located below the genial tubercle in most of the cases. Out of 300 patients, 178 (59.3%) presented at least one midline LF below the genial tubercle, with a slightly lower frequency to that reported by previous studies with frequency ranging from 74.5-85% [18,21].…”

Background to evaluate the distribution of lingual foramina (LF) and their correlation with demographic characteristics and mandible width in a series of patients subjected to cone-beam CT (CBCT). Methods CBCTs were reviewed to assess the number of all LF, midline and lateral LF. We also assessed the relationship of the number of lateral LF with gender and mandibular width using the Chi Square test. A p value < 0.05 was considered statistically significant. Results 300 patients (180 males; age range: 21-87years) were included. The highest frequency per patient was of 2 LF (97/300, 32.3%), followed by 3 (81/300, 27%) and 4 (53/300, 17.7%). No LF were observed in 2/300 patients (0.7%), while the highest number was of 8 LF in one patient. The highest frequency of midline LF per person was of 2 LF (57.3%, 172/300), while the highest number per person was 5 LF in one patient (0.3%). The highest frequency of midline LF located above and below the genial tubercle was of 1 in 197/300 patients (65.7%) and in 169/300 patients (56.3%), respectively. Concerning lateral LF, the highest frequencies were of 0 (113/300, 37.7%) and of 1 (112/300, 37.3%). We did not observe any significant difference of the number of midline and lateral LF based on gender (P = .438 and P = .195, respectively) or mandible width (P = .069 and P = .114, respectively). Conclusions We have shown the high variability of number and anatomic distribution of LF in an Italian group of patients subjected to CBCT without reporting any association with gender and mandible width.

“…Isman et al 31 state that the panoramic radiography can identify LF in the anterior part of the mandible in only 8 (4%) patients with certainty, whereas a high degree of probability for its existence was recorded in 25 (12.5%) patients. The use of CBCT results in obtaining cross-sections of high resolution and different thickness, which makes it superior to the other radiographic techniques for visualisation of LF 32,33 .…”

Background/Aim. A lingual foramen (LF) is a small opening on the lingual surface of the mandible, which is most frequently located in the middle of the anterior part of the mandible and which shows significant variations in its location, size and number. The aim of this study was to assess the location and anatomical characteristics of LF using cone beam computed tomography (CBCT). Methods. The research was designed as a retrospective study in which 99 CBCT scans were analysed. The analysis covered the number of LF, their location in relation to the teeth and the mandibular region itself, diameter, distance from the alveolar ridge crest, distance from the inferior border of the mandible, distance from the tooth apex and position in relation to the tooth apex. Results. The average frequency of LF per patient was 2.4 1.2. The largest number of LF were localised in the region of lower central incisors. Out of the total number of LF, 82.5% of LF belonged to median lingual foramen (MLF), while 17.5% belonged to lateral lingual foramen (LLF). In 63.2% cases, LF had a diameter of ?1mm, whereas in 98.3% cases it was localised below the tooth apex. There is a statistically significant difference in the distance of LF from the alveolar ridge crest and the LF diameter in relation to gender (p = 0.019; p = 0.008). Conclusion. LF can be reliably localised and visualised by means of CBCT. It is recommended that CBCT scanning of the mandible should be used while planning an oral surgical procedure and implant placement in order to prevent injuries of the neurovascular bundle which passes through LF.

“…12 It can be located mainly above and/or below the mental spines, and diameters may be associated with high risk of bleeding vessels. 7 Denny et al 6 studied the CBCT scans of 116 patients, the number of lingual foramina ranged from 1 to 3, their position was mainly (60%) in the upper two-thirds distance from the alveolar crest, and there was no significant difference in various age groups or between both genders.…”

The mental spines are bony prominences found in the lingual surface of anterior mandible, and usually they are arranged in two groups, superior pair and inferior pair. Mostly they are asymptomatic, but sometimes they may interfere with the prosthodontic treatment or with some surgeries. The lingual foramen can be found in different locations around the mental spines, and they are very important vital organ because they transmit nerves and arteries, which may cause a serious problem during some types of surgeries in this region such as implant placement. Here, we report a case of 55-year-old, Kurdish woman with elongated superior mental spine with bilaterally lingual foramina located distally to lower central incisors, that have been seen during a routine CBCT scan. The length of the spine was 6.4 mm, the height was 5.5 mm and the width was 1.9 mm. So, any dentist wants to perform any type of surgery in sublingual and submental regions should be careful of such anatomical variations.

Determination of presence and morphometry of lingual foramina and canals in Chilean mandibles using cone-beam CT images

Abstract: All the mandibles have one or more lingual foramina. The most frequent positions were superior and inferior. Many of the lingual foramina found were over 1 mm in diameter. The lingual canal length was over 5 mm for all the positions.
