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 analyzed by the generalized estimating equations [GEE] model.Results.significant difference between examiners [PAN: P=0.146; CBCT:P=0.749] was not observed. Analysis by GEE model showed no significant difference between genders[P=0.411]and examiners[P=0.183]. However, significant difference was observed for identification in both mandible right side[P=0.001], where the identification frequency was higher, and CBCT method[P<0.001].Conclusions.PAN was not shown to be a safe examination to identify MIC. CBCT should always be used in preoperative planning and to reduce the number of complications in implant surgeries.

Objective: The aim of the present study was to clarify the occurrence, diameter, and location of the accessory mental foramen (AMF) using cone-beam computed tomography (CBCT) images from a sample of Turkish children. Study design: This retrospective was carried out using a total of 275 CBCT images from child and adolescent patients were randomly selected from existing records in the Department of Oral and Maxillofacial Radiology at the University of Erciyes, Kayseri, Turkey. The mental foramen (MF) and AMF were assessed on axial, sagittal, and coronal CBCT slices. Results: The mean age was 10.51 ± 3.32 years, consisting of 139 males (mean age 10.64 ± 3.42) and 126 females (mean age 10.38 ± 3.18). Twenty-one AMFs were observed in 18 of 275 patients (6.5%, 10 boys and eight girls). There was no significant difference in gender in relation to the prevalence of AMF (p = 0.65). The mean area of the 21 AMFs and the MF on the side with the AMF were 0.7 mm2 (SD ± 0.5) and 3.8 mm2 (SD ± 2.2), respectively. Conclusion: It is important to stress that detecting the AMN using CBCT with 3D reconstructions may reduce the risk of paralysis, hemorrhage, and postoperative pain in this region. Our study presents the first report assessing the occurrence, diameter, and location of the AMF in the pediatric population using CBCT images. In this respect, not surprisingly, the mean size of the AMF of our population is smaller than other reports in the literature that involve adult populations.

Objective: The aim of this study was to evaluate the size, shape and location of the mental foramen (MF) and anterior loop (AL) in the Brazilian population through the analysis of cone beam computed tomography (CBCT) and panoramic radiography (PR). Method: We analyzed the location, shape and size of the MF, the distance between the upper wall of the MF and the alveolar crest (AC), the size of the AL and the presence of lingual anastomosis. Results: Fifty PR and CBCT exams were analyzed. In relation to the MF, the most common location was between premolars (56%), the most common shape was the oval shape (83%) and the average size in the PR was 3.63 mm and in the CBCT was3.66 mm. The average distance from the MF to the AC in the PR was 17.29 mm and in the CBCT was 11.48 mm. The average AL size was 3 mm, the smallest being 1 mm and the largest being 5 mm. Static analysis was performed to verify the relationship between the distance from the foramen to the AC with the values ​​that were found in the PR and CBCT, which showed a statistically significant difference (p=<0.001) between them. Lingual anastomosis could be seen in 22% of the analyzed hemimandibles. Conclusion: CBCT is a reliable diagnostic test for planning rehabilitation near the MF. The distance between the implant and the foramen must be analyzed individually.

The mandibular canal is an anatomic structure that extends bilaterally from the mandibular foramen to the mental foramen. Objective: To identify the presence, extension, and length of the mandibular incisive canal with a cone-beam computed tomography, and to determine correlations with the positioning of the mental foramen and mandibular canal in a selected Brazilian Amazon population. Material and methods: The measurements of the incisive canal that ends at the mandible’s lower buccal and lingual border, at its initial and terminal portions, were obtained from 95 odontological examinations using cone-beam computed tomography. These measurements were compared with the measurements of the distance between the mandibular canal ending at the same cortices in 2 distinct regions at the mental foramen region. Pearson’s correlation test was used to establish a relationship between these measurements. Results: The mandibular incisive canal’s bilateral identification mean age was of 44.29 ± 11.04 y and the mean length was 10.38 ± 4.01 mm. Moderate correlations were found between the measurements of the mandibular incisive canal, mental foramen, and mandibular canal. Conclusion: The mandibular incisive canal can reach the region of the median line, and it did not present differences between the genders or for the length and distance of the mandibular incisive canal to the cortices ending at the mandible base.

Summary Background/Aim: The aim of this study was to evaluate the distance between the mental foramen and the upper and lower edges of the mandible in the Turkish population according to different gender and age groups. Material and Methods: A total of 1756 samples of 878 patients who presented at the Dentomaxillofacial Radiology Department of the Dentistry Faculty of Dicle University were included in the study for evaluation of the distance between the mental foramen and the upper and lower edges of the mandible. The cone beam computed tomography (CBCT) images were taken using an I-CAT Vision device (Imaging Science International, Hatfield, USA). Multiple variance analysis was used in the statistical analyses of the data. Results: A statistically significant difference was identified between the genders in respect of the distance of the external edge of the mental foramen from the upper edge of the mandible (p=0,000). In the evaluations of the different age groups, no statistically significant difference was determined. A statistically significant difference was determined between the gender and age groups in respect of the distance of the mental foramen from the lower edge of the mandible (p=0,000). Conclusions: The distance of the mental foramen from the upper and lower edges of the mandible can show variations according to age and gender. Therefore, the use of CBCT as a 3-dimensional imaging method with a low radiation dose is recommended.

ABSTRACT Objective: To determine the usefulness of panoramic radiographs in determining the labio-palatal position of maxillary impacted canines (MICs) and root resorption of permanent incisors on cone-beam computed tomography (CBCT) in correlation with the mesiodistal position of MICs on panoramic radiographs. Materials and Methods: This retrospective radiographic study reviewed 64 patients with 86 MICs. Subjects were divided into two groups: group I (&lt;15 years old) and group II (&gt;15 years old). The mesiodistal position of the MICs' cusp tips was classified into five sectors on panoramic radiographs. The labio-palatal position of the MICs and root resorption of permanent incisors were evaluated on CBCT. The statistical correlation between panoramic radiograph and CBCT results was examined using the chi-square test and the Fisher exact test. Results: Most of the positions of MICs were palatal (67%), followed by labial (28%) and mid-alveolus (5%; P &lt; .05). Labial positioned MICs on CBCT were more frequent in panoramic sector 1, mid-alveolus MICs were more common in sector 2, and palatally positioned MICs were more frequent in sectors 3, 4, and 5. The association between sectors of the MICs on panoramic images and the labio-palatal position of the MICs on CBCT was statistically significant (P &lt; .001). Root resorption of adjacent incisors showed a significant difference according to sector location (P &lt; .01) and was mainly found in sectors 4 and 5. Conclusions: This study showed that the labio-palatal position of MICs and resorption of permanent incisors might be predicted using sector location on panoramic radiographs.
