Abstract: One of the most vital anatomical structure within the mandible is the mental foramen. The significance of this structure come since it is the anatomical opening of mandibular canal on the mandible bilaterally. The neuro-vascular complex leaving from the foramen has a critical and important role and giving supply to the skin and muscles of the chin, lower lip, the associated gingiva and mucosa following to the lower premolars. Subsequently, the location knowledge of the mental foramen considers an awfully significant for dental specialists to dodge harming this imperative structure via the dental working on this region, as in dental anaesthesia, dental surgery, dental anaesthesia and root canal treatment. The aim of study: The point of the think about: To assess the site of the mental foramen in relative to the mandibular premolars, depended on the panoramic and CBCT and O.P.G images. Materials and Methods: The current study involved the previous articles published from 1997 till 2019, with respect to the site of mental foramen in elderly and adult patients, in any case of the gender. All these studies were used on either the panoramic and cone-beam computed tomographic images for visualizing the site of the mental foramen. Results: Regarding the outcomes of the previous studies included in this review, the statistics appeared that the first common area of mental foramen was beneath the apices of lower second premolars in the percentage of 49.99%, the other second common area of mental foramen was between the apices of the lower first and second premolars in the percentage of 42.30%. Conclusion: The mental foramen was mostly found beneath the apices of lower first and second premolars and then between the apices of the lower first and second premolars.

ABSTRACT Objective: To investigate the relationship between anteroposterior and vertical differences in maxillofacial morphology and mandibular volume. Materials and Methods: Subjects comprised 213 Japanese adults (84 males and 129 females) who were divided into three groups based on mandibular basal arch (ANB) and Wits, measured in a cephalometric analysis: Class I (−1° ≤ ANB < 4°,−1 mm ≤ Wits < 0 mm), Class II (ANB ≥ 4°, Wits ≥ 0), and Class III (ANB <−1°, Wits <−1 mm). Subjects were also divided into three groups based on the mandibular plane angle (Mp), as follows: hypodivergent (Mp < 23°), normodivergent (Mp  =  23–30°), and hyperdivergent (Mp > 30°) groups. Mandibular volume was measured from cone-beam computed tomographic images that were analyzed using Analyze™ image processing software and compared among the three groups in each classification. Results: No significant differences were noted in mandibular volume among Classes I, II, and III. An inverse relationship was found between mandibular volume and Mp, and a significant difference was noted in mandibular volume between the hypodivergent and hyperdivergent groups. Conclusions: In addition to two-dimensional analysis, such as lateral cephalometry, three-dimensional information such as volume, provided by cone-beam computed tomography, contributes to a more detailed assessment of maxillofacial morphology.

The aim of the present study was to compare mandibular neurovascular canal anatomy in human and great apes by using cone beam computed tomography (CBCT). The anatomical variability of mandibular neurovascular canals (mandibular, incisive and lingual canals) of 129 modern humans and great apes (Homo, Pan and Gorilla) were analyzed by linear measurements on CBCT images. The Kruskal-Wallis non-parametric test and Dunn’s all pairs for joint ranks were applied to compare the variability of mandibular canals among these groups. Human, Chimpanzee and Gorilla groups showed significant differences in the dimensions of the mandibular canal, mental foramen, incisive canal, lingual canal and anterior mandibular bone width. Bifid mandibular canals and anterior loops were the anatomical variations most frequently observed in the Gorilla. Humans had a larger mental foramen and a distinctive incisive canal. The latter could not be identified in the Gorilla group. The variability in the anatomy within mandibles of human and non-human primates, shows different forms in the neurovascular structures. In comparison to the mandible of great apes, the incisive canal is suggested to be a feature unique to the human mandible.
