“…By knowing the anatomical characteristics of each patient, during various procedures such as tooth extraction, the probability of occurring some iatrogenic lesions such as bleeding, fractures and nervous lesions is very reduce. Although anatomical variations exist, they might increase the complications prevalence (Gioso et al., ; Boudrieau, ; Lommer, ; Guimarães et al, ). Thus, due to the complications and the particularity of each clinical case, it is of great benefit to plan the medical and surgery procedures using information about the localization and size of the mandible anatomical structural elements.…”

“…Mandible anatomical variations of the structure elements are a major factor implicated with complications such as overlooked or misdiagnosed of different clinical conditions. The results are particularly important during anaesthesia and surgical procedures in dental and maxillofacial practice, such as exodontias (Guimarães et al., ). Exodontia (tooth extraction) is one of the most commonly used techniques in small animal dental medicine (Girard et al., ; Holmstrom et al., ; Carreira et al., ).…”

This study was performed in a sample of 20 dogs (n = 20) and aimed to: (1) characterize the mandible height (Mh), mandibular canal height (MCh) and distance between the inter-dental alveolar margin and the mandibular canal (dIAM-MC) dimensions, and (2) to develop mathematical models that express the insight's mandible anatomy of those important mandible structural elements allowing the prediction of their dimensions using physical parameters such as patient body weight (Wg) and the canine tooth width at the free gingival margin level-(wCGM). Lateral-view X-rays of both sides of the skull were taken for all the individuals. Three mathematical prediction models were developed to calculate Mh, MCh and dIAM-MC. Achieved proportions of the mandible considered parameters regarding its height were of 36.45% for MCh, 50.90% for dMAI-MC and 12.65% for vMC. Statistically significant differences were registered between the Wg and wCGM (P = 0.00), Mh (P = 0.00), MCh (P = 0.00) and dIAM-MC (P = 0.00). Only the Wg presented a strong correlation with the wCGM (R = 0.58), Mh (R = 0.70), dIAM-MC (R = 0.60) and MCh (R = 0.68). These models will allow a clinician to estimate the size of the mandible structures by only using data obtained during the physiological examination, with a sufficiently high prediction capacity and a very low standard error. The study points out the relationships of physiological parameters such as Wg and wCGM with mandible anatomical structural elements considered as important in oral surgery. The results of this study give the surgeon a new additional tool providing more information on the mandible anatomical structures and its relationships. This reduces the risk of iatrogenic lesions during the oral surgical procedures and improves patient safety.

“…Rouas et al (2006) showed how a pseudo-enlarged mandibular canal seen on a panoramic radiograph turned out to have resulted from superimposition over a deep mylohyoid groove when viewed by CBCT. As a recurrent tumor in the vicinity of the mandibular canal has been misdiagnosed, this knowledge will also encourage extra care when dealing with clinical uncertainty (Guimaraes, Pontes, Mata Rezende Ddos, & Pontes, 2014). Added to this problem is the recent finding that tomographic images of pathologies and BMCs often coexist in the molar region (de Castro et al, 2018).…”

The mandibular canal is a conduit that allows the inferior alveolar neurovascular bundle to transverse the mandible to supply the dentition, jawbone and soft tissue around the gingiva and the lower lip. It is not a single canal but an anatomical structure with multiple branches and variations. The branches are termed accessory, bifid or trifid canals depending on their number and configuration. A bifid mandibular canal is an anatomical variation reported more commonly than the trifid variant. Because of these variations, it is of the utmost importance to determine the exact location of the mandibular canal and to identify any branches arising from it prior to performing surgery in the mandible. This article reviews the prevalence, classification and morphometric measurements of these accessory mandibular canals, emphasizing their clinical significance.

“…However, mandibular canal widening is a rare finding. When encountered, several benign and malignant conditions need to be excluded from the list of differential diagnoses before diagnosing it as a normal anatomical variant 34. Clinically, widening of the mandibular canal may be accompanied by sensory disturbances.…”

Common conditions associated with mandibular canal widening: A literature review

Purpose The aim of this study was to review the common conditions associated with mandibular canal widening. Materials and Methods General search engines and specialized databases including Google Scholar, PubMed, PubMed Central, Science Direct, and Scopus were used to find relevant studies by using the following keywords: “mandibular canal,” “alveolar canal,” “inferior alveolar nerve canal,” “inferior dental canal,” “inferior mandibular canal,” “widening,” “enlargement,” “distension,” “expansion,” and “dilation.” Results In total, 130 articles were found, of which 80 were broadly relevant to the topic. We ultimately included 38 articles that were closely related to the topic of interest. When the data were compiled, the following 7 lesions were found to have a relationship with mandibular canal widening: non-Hodgkin lymphoma, osteosarcoma, schwannoma, neurofibroma, vascular malformation/hemangioma, multiple endocrine neoplasia syndromes, and perineural spreading or invasion. Conclusion When clinicians encounter a lesion associated with mandibular canal widening, they should immediately consider these entities in the differential diagnosis. Doing so will help dentists make more accurate diagnoses and develop better treatment plans based on patients' radiographs.
