“…Various studies have reported the prevalence and characteristics of double MF and MBF, in different populations and using different instruments (Zografos & Mutzuri;Al-Khateeb et al;Manikandhan et al;Naitoh et al, 2011;Afkhami et al, 2013). The frequency of double MF has been studied in dry mandibles and in CBCT, with reported frequencies of around 7 % in Greek and Indian populations (Zografos & Mutzuri; Roopa et al), and 3 % to 13 % in Asiatic populations (Katakami et al, 2008;Naitoh et al, 2009a,b;Olivera-Santos et al, 2011;Imada et al, 2014;Srinivas et al). In our study of digital panoramic radiographs in a sample of Chilean patients, we report a prevalence of 2.58 %; this is lower than that described in the literature (around 5 %) (Naitoh et al, 2011;Al-Shayyab et al;Srinivas et al).…”

The percentage difference in the prevalence may be due to the sample size (much larger in our case) and to ethnic origin (most studies of prevalence have been carried out in Asian populations).…”

“…Fuentes et al (2014) analysed the visibility of the MF in a Chilean population sample in conventional panoramic radiographs and reported a rate of 87.9 %, observing that detection of the MF is less frequent with advancing age and that it is more prevalent in men. The variations in this foramen have been studied in different populations in dry mandibles (Zografos & Mutzuri, 1989;Roopa et al, 2003), radiographic imaging techniques like CBCT (Naitoh et al, 2009a,b) and panoramic radiographs (Naitoh et al, 2011;Al-Shayyab et al, 2016;Srinivas et al, 2017); the reported prevalence varies between 3 % and 7 %.…”

The morphological variations of the mental foramen (MF) and mandibular foramen (MBF) have been studied for several years, and the prevalence and morphometric characteristics of double and triple foramina have been reported. The objective of this study was to establish the prevalence of variations in the MF and MBF, and to carry out a morphometric analysis of a Chilean population using digital panoramic radiographs. The study included 927 radiographs; the observed prevalence of double MF was 2.58 %, while the prevalence of double MBF was 1.51 %. No cases of triple foramina were found. In men, double MF was found more frequently in the left hemiarch (64.28 % of cases), while in women it was more frequent in the right hemiarch (80 %). Double MBF was found more frequently in the right hemiarch in women (80 % of cases), while the distribution between left and right in men was even. The mean area, width and height of the double MF were 5.46 mm 2 , 2.77 mm and 2.57 mm respectively. The means of the same morphometric measurements in double MBF were 6.37 mm 2 , 2.27 mm and 3.19 mm respectively. In both foramina, statistically significant differences were only found between the height of the foramen and the age of the subjects, with the observation that the greater the subject's age, the smaller the height. Dental surgeons must take these anatomical variants into consideration in clinical and surgical actions; timely diagnosis by radiograph is important to avoid possible complications.

“…MF localization can show a variation with age and gender. In childhood, the MF is seen between the permanent canine tooth and the first molar, and in a toothless jaw it may be seen close to the upper border of the mandible due to bone resorption 6 . As a result of increased attrition related to ageing and mesialization of the teeth, the MF location shifts towards the distal 3,7 .…”

The proximity of mental foramen to mandibular first premolar teeth: Cone beam computed tomography analysis in Turkish population

et al. 2021

View full text Add to dashboard Cite

SummaryBackground/Aim: The aim of this study was to evaluate the proximity of the mental foramen (MF) to the roots of the mandibular first premolar teeth in the Turkish population according to gender and different age groups.Material and Methods: The study was conducted on 385 samples of 242 patients who presented at the Dicle University, Faculty of Dentistry, Department of Dentomaxillofacial Radiology. The proximity of the MF to mandibular first premolar teeth was examined on cone beam computed tomography (CBCT) images. Two-way Anova variance analysis was used in the statistical analyses of the data.Results: According to the analysis results, no statistically significant difference was determined between the age and gender groups (p>0.05). In the evaluation of the gender groups, the mean value was 6.6997 mm for females and 6.5445 mm for males.Conclusions: With 3-dimensional imaging technology, the CBCT system provides detailed information about the MF localization. This method has shown that the localization of the MF could change associated with variables such as age and gender.

“…3 However, the MF may be located anywhere from the mesial aspect of the 1st premolar to along the long axis of the 1st molar due to individual anatomical variations. 4 Also, there have been variations in the horizontal position of MF in different racial groups and populations of various geographical locations [4][5][6][7][8][9][10][11][12] .…”

Objective: To radiographically determine the mental foramen position, its distance to the nearest apex and the prevalence of anterior loop of mandibular nerve using cone-beam computed tomography scans. Method: The cross-sectional study was conducted at the Aga Khan University Hospital, Karachi, from January to June 2020, and comprised cone-beam computed tomography scans of males or females of Pakistani origin aged 15-65 years with intact mandibular dentition and fully formed roots with matured apex. The scans were analysed to determine the horizontal position of mental foramen and to classify it according to the Tebo and Telford classification. The vertical distance from mental foramen to the nearest tooth apex was measured and the mandibular nerve configuration was determined. Data was analysed using SPSS 23. Results: Among the 96 scans, the most frequent location of mental foramen MF was along the long axis of 2nd premolars for both right 50(52.1%) and left 49(51%) sides, followed by between 1st and 2nd premolars for both right 28(29.2%) and left 38(39.6%) sides. The mean minimum distance from mental foramen to the nearest root apex was 3.75±2.59mm and 3.99±2.26mm on right and left sides, respectively. There was bilateral symmetry on both sides. The most frequent mandibular nerve configuration on the right 69(72.6%) and left 75(78.1%) sides, with anterior loop being the least common; right side 3(3.2%) and 5(5.2%) left side. Conclusion: The most common position of mental foramen was along the long axis of 2nd premolars while the anterior loop was the least common. Key Words: CBCT, Mental foramen, Mandibular teeth, Pakistani population, Tebo and Telford classification, Mandibular nerve.
