“…An odontoma is a tumour formed by the dental tissue that presents itself as a calcified mass, with a rounded or irregular shape. 22 The treatment consists of surgical removal. 23 Six cases of periapical cyst ( Figure 5) and one dentigerous cyst were found in this study.…”

Objectives: The aim of this study was to identify the type and frequency of incidental findings (IFs) in the maxillofacial region of CBCT scans with different sizes of field of view (FOV), and the clinical relevance of the findings was classified as requirement or not of monitoring, treatment or referral to a specialist. Methods: We analyzed 150 CBCT examinations, divided according to the size of the FOV into 3 groups: 6-cm maxilla, 6-cm mandible and 13-cm maxilla/mandible. The IFs were categorized into six areas: airway, temporomandibular joint (TMJ), bone, lesions of the jaws, teeth and soft-tissue calcifications. Results:The results showed 560 IFs that were found in 92% of the samples studied. A total of 225 IFs were found in examinations of the maxilla group, 99 findings in the mandible group and 236 findings in the maxilla/mandible group. The IFs were most frequent in the tooth zone (27.32%), followed by airways, soft-tissue calcifications, TMJ, bone, lesions of the jaw and other findings. We also found that 43.46% of the IFs did not need treatment or referral to another professional, 28.97% findings required the acquisition of new images for monitoring and 27.55% findings needed treatment or referral. Conclusions: The present study confirmed the high frequency of IFs in CBCT scans. It was concluded that it is necessary to interpret and report the total volume obtained in CBCT examinations and not only the purpose of the examination region.

“…It appears as a mixed radiolucent-radiopaque mixed tooth-like structure surrounded by a dense cortical border. Differential diagnosis include; cementofying or ossifying fibroma, adenomatoid odontogenic tumour and periapical cemental dysplasia (1,2,13,14). Panoramic radiographs help to evaluate the vertical position of the odontomas and occlusal radiographs are used to evaluate the proximity to adjacent teeth; however, CBCT scan offers volumetric images (2,13,14,16).…”

“…Compound odontomas involve all dental structures and have numerous tooth-like structures. Complex odontomas are malformations in which all dental tissues are present in a disorder pattern (2,4,5). They are usually asymptomatic and usually diagnosed in routine radiographs.…”

In our cases diagnosis of the odontomas was made on panoramic radiographies; however, it is not always possible to determine the presence of any supernumerary teeth or impacted permanent teeth because of the superimposition of the odontoma.…”

Aim: The objective of this study was to evaluate the clinical and radiographic features of unerupted odontomas of the jaws. Material and Method:A total of 23 odontomas detected in 21 patients were included in our study. The lesions diagnosed on panoramic radiographs were further evaluated with cone beam computed tomography (CBCT). Patients' age, gender, clinical symptoms, localization, type, presence of supernumerary tooth with odontoma, position (buccal, palatinal, between teeth), distance to crown/ root, distance to cortical plate, any complications due to odotoma or treatment method were evaluated.Results: Twenty-three odontomas were evaluated using CBCT. Fifteen lesions located in the maxilla whereas 8 lesions located in the mandible. The closest distance of the odontoma to the neighbouring crown/root varied between 0 to 4.5 mm with a mean of 1.3 mm. The closest distance of the odontoma to the buccal/palatal/lingual cortical layer varied between 0 to 4.6 mm with a mean of 1.8 mm. Associated impacted permanent teeth were left to erupt spontaneously or orthodontic traction was started at the same time or at a later stage. Seven of the impacted teeth were orthodontically tracked during surgery and 1 tooth was orthodontically tracked at a later stage. 2 teeth were extracted during surgery and 2 teeth were left to erupt spontaneously. Conclusion:Odontomas mostly located close to adjacent cortex; therefore, practitioners will not have difficulty in exploring the lesion. However; close proximity to associated tooth may result in tooth or root damage during surgical removal. We recommend CBCT evaluation for accurate surgical planning before removal of odontomas.
