Objective This study aimed to radiographically assess the prevalence and location of accessory foramina in the human mandible using helical computed tomography (CT) images and three-dimensional reconstructions. Methods Helical CT images from 24 males and 22 females aged 66-88 years (mean age: 73.7 ± 5.3 years) were observed. Each image was assessed in the three anatomical planes, and three-dimensional reconstructions were performed with Amira 5.6 software. Results All subjects (n = 46) presented at least one accessory foramina. A lingual foramen was the most frequently observed foramen and present in 96 % (n = 44) of subjects. Mandibular anterior nutrient canals were clearly observed in 72 % (n = 33) of subjects (71 %, n = 17, of males; 73 %, n = 16, of females). A retromolar foramen was present in 17 % (n = 8) of subjects (21 %, n = 5, of males; 14 %, n = 3, of females). A double mental foramen (DMF) was present in only one subject (2 %). Fifty percent (n = 23) of subjects presented one or more inferior retromental foramen (IRF). No significant correlations were observed between prevalences of accessory foramina and sex. Conclusions The lingual foramen can be considered a constant finding, and mandibular anterior nutrient canal foramina and IRF were present in the majority of subjects.Retromolar foramina and DMF were less common but can be associated with anesthetic failures and oral surgery complications. Three-dimensional reconstructions provided better understanding of the locations of foramina and their interrelations with the anatomy of the jaw.

“…Anatomic variation and the fact that the nerves are deeply placed might not allow objective location of the neurovascular bundle. Studies have shown anesthetic success rates of 75 -97 % with peripheral nerve stimulator (36). Although Hannan et al (37) found the nerve block administered with ultrasound accurate, it did not result in a more successful pulpal anesthesia.…”

Abstract:A thorough anatomical knowledge is very essential for clinical practice and any surgical procedure. Unfortunately anatomical variations can lead to hazards in medical and dental diagnosis and treatment. Such knowledge is very essential even in effective local anesthesia which is an essential part of treatment in patients with many oral disorders. Therefore a normal anatomy and its possible variations are utmost important aspects also in dentistry. One of the structures that dentists very often deal with is the mandibular nerve which therefore needs a thorough review. However, there are not many consolidated literature reviews available regarding its variations and clinical applications. Keeping this in mind, in this article, the authors have brought together available literature on various aspects of mandibular nerve. The fi nal review will be of benefi t to clinicians (Fig. 2 A thorough anatomical knowledge is very essential for clinical practice and any surgical procedure. The idea of exact location of various structures in the body prepares the clinician for a better approach in diagnosis and intervention. Unfortunately, the anatomical variations can lead to hazards in medical and dental diagnosis and treatment. Such knowledge is very essential even in effective local anesthesia which is an essential part of treatment in patients with many oral disorders. Therefore a normal anatomy and its possible variations are utmost important aspects also in dentistry. One of the structures that dentists very often deal with is the mandibular nerve which therefore needs a thorough review. However, there are not many consolidated literature reviews available regarding its variations and clinical applications. Keeping this in mind, in this article, the authors have brought together literature available on various aspects of mandibular nerve. The fi nal review will be of benefi t to clinicians.The mandibular nerve, largest division of trigeminal nerve, supplies the mandibular teeth and gums, mucosa of the anterior two thirds of the tongue, fl oor of the oral cavity, skin of the temporal region, part of the auricle and external acoustic meatus including the tympanum, lower lip, and lower and posterior parts of the face. Developmentally, it is the post-trematic nerve of the fi rst pharyngeal arch and therefore contains the motor fi bers to the muscles developed from the fi rst pharyngeal arch. It is a mixed nerve formed by the union of a large sensory root, branch of the lower part of the trigeminal ganglion and a smaller motor root from the pons which courses under the trigeminal ganglion. Both roots exit through the foramen ovale and unite just outside the foramen to form the trunk of the mandibular nerve which descends between the tensor veli palatini and lateral pterygoid muscles, gives off a meningeal branch and the nerve to medial pterygoid branch and ends by dividing into a smaller, mostly motor anterior branch and a larger, mostly sensory posterior branch. It contains about 78,000 myelinated fi bers. The nerve...
