Appearance of the mandibular incisive canal on panoramic radiographs
Surgical and Radiologic Anatomy, 2004
Panoramic radiographs are routinely used in the dental office for various diagnostic purposes. This study aimed to evaluate the visibility of neurovascular structures in the mandibular interforaminal region on such radiographs. Panoramic radiographs were obtained with a Cranex Tome (Soredex) from 545 consecutive patients using a standard exposure and positioning protocol. For visibility scoring of neurovascular structures, a four-point rating scale was used. The mandibular canal and the mental foramen could be observed in the majority of the cases with good visibility. The lingual foramen was visualized in 71% of the cases, with good visibility in 12%. An incisive canal was identified in 15% of the images, with good visibility in only 1%. An anatomical variation to be considered is the anterior looping of the mental nerve (in 11% of images). Panoramic radiographs can be used for visualization of the mental foramen and a potential anterior looping but not for locating the mandibular incisive canal. To verify its existence for preoperative planning purposes, cross-sectional imaging modalities (HR-CT or spiral tomography) should be preferred.

Objectives.The region between mental foramens is considered as a zone of choice for implants. However, complications may arise due to an extension anterior to the mental foramen that forms the mandible incisive canal [MIC]. Our goal is to evaluate identification of MIC by both panoramic radiograph [PAN] and cone-beam computed tomography [CBCT].Methods.150 cases with bilateral MIC were analyzed. Images of a radiolucent canal, within the trabecular bone, surrounded by a radiopaque cortical bone representing the canal walls, and extending to the anterior portion beyond the mental foramen, were considered by two independent radiologists as being images of MIC. PAN and CBCT of these cases were evaluated by 2 other radiologists at different times. Agreement between results of examination methods was assessed by the Kappa coefficient. The interexaminer and intramethod rates for detection of MIC were analyzed by the McNemar test. Gender, mandible side, examiner, and type of method were anal...

The objective of the present study was to evaluate the presence and course of the incisive canal in the mental interforaminal region of the human mandible and to describe the occurrence of anatomical variations. Mandibles of 50 adult human cadavers were retrieved from the Department of Anatomy of the Faculty of Medicine, Katholieke Universiteit Leuven (Leuven, Belgium). Forty mandibles were edentulous, while 10 mandibles were partially dentate. Intra-oral, panoramic and tomographic imaging of the interforaminal region of the human mandible were performed. Afterwards, mandibles were sawn into vertical sections according to the respective tomographic cross-sections. The latter allowed exploration for the presence and course of an anterior prolongation of the mandibular canal. Mea-urg Radiol Anat (2003) 25: 416-423

Objectives: This study was conducted to assess appearance, visibility, location and course of anatomical landmarks in mandibular interforaminal region using cone-beam computed tomography (CBCT). Study design: A total of 96 CBCT examinations was re-evaluated to exploit anatomical landmarks. The examinations used the Promax 3D CBCT unit. A sole examiner carried out all the measurements. Visibilities of the anatomical landmarks were scored using a four-point rating scale. Results: The mandibular foramen, anterior loop, incisive canal and lingual foramen were observed in 100,84,83,49 % of the images, respectively. The mean size, diameter and width of anterior loop, incisive canal and lingual foramen were obtained 3.54± 1.41, 1.47±0.50 and 0.8 ± 0.09mm, respectively. Conclusion: It is not safe to recommend any definite distance mesially from the mental foramen. The diameter of the canals and foramens should be determined on a case-by-case basis to exploit the appropriate location for each individual.

background and Aim: The aim of the present study was to assess the spiral computed tomography (CT) scans for the presence/ location, course and dimension of the incisive canal and also to analyze the potential inter-examiner differences regarding incisive canal related-measurements. Materials and Methods: A total of 90 spiral CT scans were analyzed by three different observers (two oral radiologist and one periodontist) on predetermined sections by a CT specialist. Vertical and horizontal diameter of the incisive canal, the horizontal distance to the buccal and lingual borders, vertical distance to the teeth apicies/crest of ridge and inferior border were measured on CT scan sections. results: There was a good level of agreement regarding incisive canal related measurements among the three observers. Incisive canal may be located in a large variety of distances and diameters. A trend of decrease in the vertical and buccolingual diameter was noted as the canal proceeded medially. Inc...
Mandibular incisive canal in edentulous patients: Analysis by means of digital panoramic radiography
Dental Press Implantology, 2014
/ Introduction: he aim of this study was to radiographically assess the region between the mental foramina for the presence and characteristics of mandibular incisive canal, a major repair associated with postoperative complications of osseointegrated implant placement surgeries. Material and Methods: Fifty-two edentulous patients treated during twelve months in the Dental Clinics of the Federal University of Bahia underwent digital panoramic examination. he images were evaluated by a single radiologist and the presence of the mandibular incisive canal, its length, the shape of its trajectory and the distances from the alveolar crest and mandibular base were recorded. Results: he inal sample consisted of 49 exams. Mandibular incisive canal was observed in eight radiographs, and accounted for 16.3% of the population investigated, with length varying from 10.7 to 19.7 mm. Bilateral lesions were more frequent (50%), and so was the horizontal path (5 cases). Final consideration: he presence and intraosseous anatomy of mandibular incisive canal should not be ignored in surgical planning involving the anterior mandible region. his becomes critical to prevent perioperative complications and also to prevent the occurrence of sensory and bleeding disorders in the postoperative period.

Citation: Aljafari AA (2021) Evaluation of the Morphology of Mandibular Incisors . J Ora Med Vol.5 No.5:e112. One of the foremost vital factors within the success of passage treatment is that the data regarding the foundation canal system anatomy. Among the foremost reasons for the failure of the treatment, one will name the dearth of data regarding pulp anatomy, solely the second to inaccurate identification and treatment arrange. Though specific anatomy is considered the foremost common kind for every tooth in several textbooks, there exists an excellent anatomical diversity regarding the foundation canal system. Today, picture taking analysis in endodontic is essentially restricted to standard intraoral and broad radiographs. Intraoral radiographs give helpful info regarding the presence and site of periapical lesions, passage anatomy, and proximity to anatomical structures. However, the two-dimensional nature of the created pictures poses bound limitations in terms of anatomic d...

Purpose The purpose of this study was to analyze the frequency of visualization of anatomical bone features and their possible variations in the mandibular interforaminal region through cone-beam computed tomography (CBCT). Methods This is a cross-sectional study that evaluated CBCT scans of the mandible of 141 women and 61 men, obtained by imaging archives from two private clinics of dental radiology. The study analyzed the frequency of visualization of: lingual symphyseal foramen (LSF), additional mental foramen (AdMF), absence of mental foramen (AbMF), mandibular incisive canal (MIC), and anterior loop (AL). Length measurements for MIC and AL were determined at first and following that the respective distances towards vestibular and lingual cortical walls were also individually verified. Statistical analyses included: Student's t test, Chi-square test, and ANOVA for the evaluation of the anatomical features observed through panoramic and parasagittal images' reconstructions. Results LSF presence was found in 97%, MIC in 75.9%, AL in 24%, AdMF in 4.7%, and AbMF in 2.5%. Chi-square tests demonstrated value results of p < 0.05 only for the presence of left AL in women when compared to men. Mean values for length measures of MIC and AL were of 10.1 and 2.12 mm, respectively. Mean distance from AL towards vestibular and lingual cortical walls was of 2.53 and 4.05 mm, respectively. Conclusion Anatomical variability concerning the mandibular interforaminal region emphasizes the importance of performing CBCT in pre-operative assessment of the mandible for surgical procedures with oral implants.
