“…The present study results were also in the same range (18.8%), but they did not show statistically significant association with the internal structure of the lesion (p >0.05). The lesions of OKCs can also cause tooth root resorption rarely and this rate was reported to be 8%-41%, which was similar to the current study where 31.3% of the cases were causing root resorption [13,20].…”

IntroductionAn odontogenic keratocyst (OKC) is a benign intraosseous lesion with potential to demonstrate aggressive and invasive behavior. The aim of this retrospective study was to analyze the imaging features of the OKC using cone-beam computed tomography (CBCT) and to evaluate the association between the internal structure of the lesion and the effect of the lesion on surrounding structures. MethodsOverall, 32 CBCT scans of histopathologically diagnosed cases of OKC were analyzed retrospectively. The following variables were analyzed: anatomic location of the lesions (mandible body (right/left), ramus (right/left), mandible body+ramus (right/left), maxilla (right/left), and both jaws), the internal structure of the lesion (unilocular/multilocular), and the effect of the lesion on the surrounding anatomical structures (involvement of the inferior alveolar nerve canal (IANC), displacement of the IANC, cortical expansion, displacement of the tooth, resorption of the root, associated impacted tooth, associated missing tooth). We also looked for the association between the internal structure and the effect of the lesion on anatomic structures. ResultsOut of 32 cases, 29 (90.6%) cases involved the mandible alone. Statistically significant association (p-value 0.005) was present between the internal structure and mean age of presentation as well as between the internal structure and impacted tooth (p-value 0.027). The association between the internal structure and other variables was statistically not significant. ConclusionsThe radiographic features of OKCs can be variable, and these lesions have a considerable effect on the tooth, IANC, and cortical bone. Significant association was found between the internal structure, age, and impacted tooth. Since OKCs have a high recurrence rate, CBCT is advised for evaluating the extent and location of any cortical perforations.

“…Considering that OK is usually asymptomatic with no or a mild associated bone cortical expansion, t he lesion is frequent ly detected on routine radiographic examinations [4,6]. Often the OK is an incidental finding on a panoramic radiography because such radiographic examination is widely used in Dentistry [8,13]. The present study ratifies these data because detection of the probable OK was incidental on a panoramic radiography.…”

“…In the study of Sánchez-Burgos et al [16], the prevalence was 71%. Shudou et al [19] detected such evidence on 66% of the cases, while Gumusok et al [8] observed it on 50% of the OKs. Such conclusions of the literature are in accordance to the present study that involves a unilocular and hypodense extensive mandible lesion.…”

“…In the study of Gumusok et al [8], 90% of OKs in the jaw induced resorption of mandibular canal walls and 60% caused displacement of this anatomic structure. Similarly, the present study reveals interruption of mandibular canal walls by the lesion, as pointed out in figure 4.…”

“…Sectional images can also reveal external root resorption associated to the lesion [11]. In a retrospective study, Gumusok et al [8] analyzed 28 patients presenting an OK, so that associated root resorption was observed in 6 of them (30% of patients). In a comparative study, Alves et al [2] reported root resorption related to 1 of 9 OKs (11% of the cases).…”

In the literature, several studies have investigated cone beam computed tomography (CBCT) findings of microscopically confirmed odontogenic keratocysts (OK). Such data can be useful on clinical routine in the diagnosis of bone lesions to define a hypothesis of OK before surgical resection. Objective: To report a clinical case of an extensive bone lesion in the mandible, which tomographic and clinical findings suggested OK as the first hypothesis. Case report: A 14-year-old male underwent a CBCT scan of the mandible for investigating an asymptomatic radiolucent bone lesion detected in a panoramic radiography. Clinically no swelling was evident and the adjacent teeth presented positive response to pulpal sensitivity test. CBCT images revealed a hypodense and unilocular lesion extending from mandibular left central incisor region to mandibular left first molar site; from jaw base to periapical region of the adjacent teeth; from buccal to lingual bone cortical. At the site of the lesion, there was erosion of the buccal and lingual bone cortical, which presented a mild expansion. Additionally, sectional images showed scalloped edges of the lesion, slight external root resorption at the apex of mandibular left second premolar, subtle incomplete septa and mandibular canal involvement by the lesion. Conclusion: The relevant CBCT findings contributed to suggest a probable hypothesis of OK in the diagnosis of a mandibular bone lesion. However, final diagnosis depends on microscopic examination.

Mandibular canal vs. inferior alveolar canal: Evidence‐based terminology analysis

et al. 2020

View full text Add to dashboard Cite

Introduction The mandibular canal, as it was formerly named in Terminologia Anatomica (TA), has also been called the inferior alveolar (nerve) canal in many scientific publications. This study was conducted to investigate how these terms have been understood in different regions and different areas of expertise and to discuss the appropriate future application of the term “mandibular canal.” Methods A literature search was conducted using PubMed, and articles using different terms for this structure were classified into two groups, inferior alveolar canal/inferior alveolar nerve canal (IAC/IANC) and the mandibular canal (MC). The 50 most recent articles in each group were included. Publication year, journal title, country of the first author, and affiliation of all authors were recorded in both groups for all 100 articles. Results There was a significant difference between the IAC/IANC and MC groups in the numbers of anatomy journals, other journals, and anatomy affiliations. Turkey published most frequently with a total of 15 articles, followed by Iran with 10 articles, and China/India/United States with seven each. When the six countries of the first author that had three or more publications in each group were compared, only Turkey appeared in both groups; otherwise, different countries were in the two groups. Conclusions Based on the results of this analysis, and considering that the tentative new term “inferior alveolar foramen” is used in the latest TA, we suggest that the mandibular canal should be renamed the “inferior alveolar canal.”
