Background: The morphological knowledge of the mandibular foramen is very important during dental procedures involving lower jaw, as structures that pass through this foramen are at risk. Inferior alveolar nerve (IAN) block is the most frequently used nerve block technique in dental practice. Location of mandibular foramen is clinically important in Inferior alveolar nerve (IAN) block, dentoalveolar surgery planning, and various endodontic treatments. Present study aimed to locate the precise location of mandibular foramen in relation to the borders of the mandibular ramus, its distances from different bone landmarks on internal surface of ramus of dry mandible and incidence of occurrence of accessory mandibular foramen in local population. Material And Methods: Present study was a cross-sectional study of 50 (fty) dry adult human mandibles, obtained from the dissection room of the department of Anatomy, NMCH, Patna, Bihar. Location of MF(Mandibular foramen) from various parameters was determined with digital Vernier calipers. The presence of accessory mandibular foramen in and around mandibular foramen on the medial surface of mandibular ramus was by simple visual observation with the help of a magnifying lens and their prevalence rate was noted. All the above parameters were carefully documented and statistically analysed. Statistical analysis was done using SPSS version 23. Student's t test was used as test of signicance to compare the mean values of right and left sides and a P-value less than 0.05 was taken to be statistically signicant. Results: Total 50 dry adult human mandibles were studied. The mean distance of mandibular foramina to anterior border of ramus was 16.97 ± 2.13 (R) mm and 17.04 ± 2.72mm(L), to posterior border was (R): 13.73 ± 2.28 mm and (L): 14.16 ± 2. 05 mm, to mandibular notch was (R): 20.50 ± 2.11 mm and (L): 20.10 ± 2.82 mm and to inferior border was (R): 26.93 ± 3.09 mm and (L): 26.37 ± 4.25 mm. We noted that there was no signicant difference in the values on the right and left sides (p>0.05). All mandibles (100%) have bilateral mandibular foramen. Unilaterally Single Accessory mandibular foramen was present in 11 (22%) mandibles. Unilaterally double accessory mandibular foramen was present in 06 (12%). Bilateral double accessory mandibular foramen was noted in 02(04%) mandibles only. Bilateral single accessory mandibular foramen was noted in 04(08%) mandibles. Conclusion: Present study provides valuable information regarding distances between mandibular foramen and surgically encountered anatomical landmarks, which is very useful to dental surgeons.

Context: Mandible is the lower jaw bone providing attachment of muscles of mastication and facial expression and provides pathway for inferior alveolar nerve and vessels. The mandibular ramus is almost vertical in adult but more oblique in old age. The anterior part of ramus can be used as the donor site for reconstruction of small bone defects in the oral and maxillofacial region. A relatively short mandibular ramus may be an important unfavorable anatomic factor in difficult laryngoscopy. The aim of this study was to determine the morphometry of mandibular ramus from various anatomical landmarks in one hundred eighty five dry adult human mandibles. Materials and Methods: A cross-sectional, analytical type of study was conducted in the department of Anatomy, Dhaka Medical College, Dhaka from July 2010 to June 2011. Morphometry of mandibular ramus was measured with the help of digital sliding calipers. Results: The mandibular ramus was at the same distance from each landmark on both sides demonstrating symmetry. There was no significant difference in the values on the right and left sides of the mandibles. Conclusion: Anatomical knowledge of this study might be useful in certain surgical procedure.

Context: Mandible is the lower jaw bone providing attachment of muscles of mastication and facial expression and provides pathway for inferior alveolar nerve and vessels. Adequate anaesthesia is a prerequisite of most of the dental procedures. Effective pain control in dentistry may be achieved by the local anaesthetic techniques; the most common procedures which are followed by the inferior alveolar nerve block. Therefore, identification of mandibular foramen is important for dental surgeons in nerve block and surgical procedures to avoid injury to neurovascular bundle. The aim of this study was to determine the position of the mandibular foramen from various anatomical landmarks. Materials and Methods: A cross sectional analytical type of study was carried out in the department of Anatomy, Dhaka Medical College, Dhaka on one hundred and eighty five (185) dry adult human mandibles of unknown sex. Position of mandibular foramen was determined using the distance of the mandibular foramen to (a) the anterior border of the ramus (b) the posterior border of the ramus (c) the mandibular notch (d) the head of the mandible (e) the posterior edge of third molar socket and (f) the symphysis menti which were measured with the help of digital sliding calipers. Results: The mandibular foramen was at the same distance from each landmark on both sides demonstrating symmetry. There was no significant difference in the values on the right and left sides of the mandibles. Conclusion: Anatomical knowledge of this study might be useful in certain surgical procedure.

El foramen mandibular es un importante hito anatómico. Para procedimientos como el bloqueo alveolar inferior del nervio, el tratamiento con implantes y osteotomías mandibulares, un profundo conocimiento de la ubicación del foramen mandibular (MF) y el foramen mandibular accesorio (AMF) es un requisito previo. Hay pocas referencias en la literatura con respecto a la localización anatómica exacta del foramen mandibular. Por lo tanto, el presente estudio tuvo como objetivo identificar la ubicación exacta de la MF y la incidencia de la AMF alrededor MF en una población india. Sesenta (60) mandíbulas humanas adultas fueron estudiadas para determinar la distancia del LV de la los anteriores, bordes posteriores de la rama mandibular, maxilar inferior categoría y el ángulo de la mandíbula. AMF todo el MF también fueron estudiados por su presencia y números. La distancia media de MF del borde anterior de rama mandibular fue 15,72 ±2,92 mm(lado derecho), 16,23 ±2,88 mm(lado izquierdo), de borde posterior fue 13,29 ±1,74 mm(lado derecho) y 12,73 ±2,04 mm(a la izquierda lado). La MF se encuentra 22,70 ±3 mm(lado derecho) y 22, 27 ± 2,62 mm(lado izquierdo) de la muesca mandibular. La distancia de MF de ángulo de la mandíbula fue 21,54 ±2,92 mm(lado derecho) y 21,13 ±3.43 mm(lado izquierdo). AMF estuvieron presentes en el 16, 66% de las mandíbulas. En 10% de las mandíbulas una sola AMF estaba presente y en el 6,66% hubo dos agujeros presentes. La ubicación del MF y AMF es importante para evitar compli-caciones como hemorragia y parestesia durante los procedimientos quirúrgicos orales y también para los radioterapeutas en la planificación de la radioterapia.  The mandibular foramen is an important anatomical land mark. For procedures like inferior alveolar nerve block, implant treatment and mandibular osteotomies, a thorough knowledge of the location of the mandibular foramen (MF) and accessory mandibular foramina (AMFs) is a prerequisite. There are few references in the literature regarding the exact anatomical location of the mandibular foramen. Therefore, the present study was aimed to identify the precise location of the MF and the incidence of AMFs around MF in an Indian population. Sixty (60) adult human mandibles were studied to determine the distance of the MF from the anterior, posterior borders of the mandibular ramus, mandibular notch and angle of the mandible. AMFs around the MF were also studied for their presence and numbers. The average distance of MF from the anterior border of mandibular ramus was 15.72 ±2.92 mm(right side), 16.23 ±2.88 mm(left side), from posterior border was 13.29  ±1.74 mm(right side) and 12.73 ±2.04 mm(left side).The MF was located 22.70 ±3 mm(right side) and  22.27 ±2.62 mm(left side) from mandibular notch. The distance of MF from angle of mandible was 21.54 ±2.92 mm(right side) and 21.13 ±3.43 mm(left side). AMFs were present in 16.66% of mandibles. In 10% mandibles a single AMF was present and in 6.66 % double foramina were present. Location of MF and AMF is important to avoid complications like hemorrhage and paresthesia during oral surgical procedures and also for radiotherapists in planning radiation therapy.

Purpose: The mandibular foramen, located on the internal surface of the mandibular ramus, is an important anatomical landmark for the success during the inferior alveolar nerve block. This cross-sectional retrospective study aimed to evaluate the location of the mandibular foramen through Cone-Beam Computed Tomography (CBCT) in different facial shapes. Materials and Methods: The determination of the location of the mandibular foramen was performed using CBCT of mesocephalic, dolichocephalic and brachycephalic patients (n=40 each). The ramus width (W), the distance from the mandibular foramen to the deepest point of the anterior border of the mandibular ramus (D), the distance from the mandibular foramen to the lowest point of the mandibular notch (V) and the distance from the inferior border of the mandible to the lowest point in of the mandibular border (R), as well as the ratios W/D and V/R, were measured. ANCOVA, two-way ANOVA and Chi-square tests were used to analyze the variation among the facial shapes. Results: The ramus width (W) was greater (p<0.0001) in the brachycephalic (28.4±0.5 mm) than in both mesocephalic (26.8±0.36 mm) and dolichocephalic (25.5±0.39 mm) patients. D (p=0.0433) and R (p=0.0072) were also greater in the brachycephalic (17.7±0.36 mm; 43.4±0.75 mm, respectively) than dolichocephalic (16.5±0.3 mm; 40.3±0.63 mm, respectively), but both did not differ from mesocephalic (17.3±0.36 mm; 41.8±0.66 mm, respectively) patients. The other measurements (V, W/D and R/V) did not significantly differ among facial shapes. Conclusion: The localization of the mandibular foramen was, in the horizontal direction, more posterior in the brachycephalic patients and, in the vertical direction, higher in the dolichocephalic patients, when compared to the other groups analyzed. Thus, the anatomic data found in this study may help dentists to increase the success of the inferior alveolar nerve block and prevent surgical complications.

Background: The inferior alveolar nerve (IAN) block is the most commonly used mandibular injection method for local anesthesia in restorative and surgical procedures. Ultrasound images can provide more accurate information about the location of the inferior alveolar neurovascular bundle. Objectives: This study aimed to evaluate the ultrasound images of patients to determine the location of the mandibular foramen (MF) relative to the adjacent landmarks. Patients and Methods: In this cross-sectional analytical study, 50 patients were subjected to intra-oral ultrasonography of the right and left sides of the mandible. An Alpinion ultrasound system (Seoul, South Korea) was used for detecting the MF, as well as its distance from different landmarks. Results: In all patients, the MF was found using color Doppler ultrasonography. The probability of detecting MF in conventional ultrasonography was estimated at 36% and 18% for the right and left sides of the mandible without using the Doppler technique, respectively. The mean MF distance from the anterior border of the ramus was 14.6 ± 2.1 and 16.1 ± 2.1 mm on the right and left sides, respectively. Also, the vertical distance of MF from the occlusal plane was 7.5 ± 1.1 mm on the right side and 8.7 ± 1.2 mm on the left side of the mandible. In all studied patients, the MF was above the occlusal plane. Conclusion: The results of this study showed that ultrasonography is not only a suitable option for intra-oral imaging due to its non-ionizing beams, but is also appropriate for localization of the MF and its related landmarks.

Objective: This study proposed to locate the mandibular foramen position by using cone beam computed tomography (CBCT) imaging, based on landmarks used at inferior alveolar nerve block (IANB) technique in order to increase the success rate of this procedure. Materials and methods: 58 mandibular foramina of 29 adult patients were evaluated. Linear and angular CBCT measurements were defined for the mandibular foramen based on the IANB technique. The measurements were performed by two radiologists. Data analyses consisted of verifying the normality, obtaining the mean value of all patients and comparing the data obtained between male and female patients. Results: Student’s t and Mann-Whitney’s U tests were used to calculate the mean mandibular foramen position. The three mean position measurements of the mandibular foramen were 13.5 mm above the occlusal plan (15.5 mm for male and 11.7 mm for female patients), 14.6 mm below the mandibular notch (14.9 mm for male and 13.7 mm for female patients) and 14.2 mm from the anterior border of mandibular ramus (14.6 mm for male and 13.8 mm for female patients). The angle formed by the molar lines and contralateral premolar lines was 25.8° and the angle formed by the molar lines and contralateral second premolar/molar lines was 31.5°. Conclusion: CBCT images were a useful method to provide the measurements of the mandibular foramen position based on landmarks used by the IANB technique. We encourage the use of these measurements as reference to increase the clinical success when performing the IANB technique.

ABSTRACT Background One of the major hurdles in clinical prosthodontics has been the selection and replacement of maxillary anterior teeth in the absence of pre-extraction records. The aim of this study was to determine if a relationship exists between intraoral and extraoral facial measurements that could assist dental practitioners in selecting esthetically appropriate maxillary anterior teeth in the absence of pre-extraction records. Materials and methods A cross-sectional study design was used with a sample size of one hundred and twenty participants. A questionnaire was used to identify the selection criteria and a photograph was taken for facial measurements using digitally calibrated software. Ninety-eight participants met the selection criteria and were included in the study. Measurements of intraoral landmarks were taken from stone casts of maxillary impressions using calibrated digital calipers. Each measurement was completed by two assessors to obtain mean values. Data were statistically analyzed using SPSS version 17 software. Data were assessed by one way analysis of variance (ANOVA) followed by post hoc (p < 0.05) to find any difference between tested groups. Pearson coefficients were used to determine whether correlation exists between measurements. Results The mean values for intraoral maxillary landmarks were: Central incisor width = 8.39 mm, circumferential canine tip to canine tip distance = 34.89 mm, arch width = 48.24 mm, left arch length = 45.24 mm, right arch length = 45.56 mm. The mean values for extraoral landmarks were: Intercanthal distance = 33.24 mm, interpupillary distance = 60.68 mm, interalar distance = 38.27 mm, intercommissure distance = 50.61 mm. Differences existed within subgroups for all intraoral and extraoral measures. A weak positive correlation existed between intraoral (r < 0.4) and extraoral measurements (r < 0.38) that remained consistent when examined by gender. Conclusion This study showed that the average length and width of the maxillary arch and interalar width were the anatomical landmarks that provided the strongest predictive relationship with anterior maxillary teeth (r = 0.38 – 0.4). Using these dimensions an average multiplying factor can be used to calculate maxillary incisor width or canine tip to canine tip distance. As the predictive strength is not strong, the authors recommend its use as a preliminary guide for determining the width of the maxillary anterior teeth during the initial selection of artificial teeth in the absence of pre-extraction records. Clinical Significance The results of this study can be used to help dentists select the size of artificial maxillary anterior teeth in the absence of pre-extraction records.
