Keratocystic odontogenic tumor is a special type of odontogenic cyst. Frequent recurrence after surgical removal, world health organization termed it as a tumor instead of cyst. It is a real challenge for oral and maxillofacial surgeon to deal with this tumor. To manage this tumor, a detailed radiological diagnosis may be of a great help to prevent recurrence. In this presented case, we used Cone beam computed tomography to find out the margin of the extension of cortical perforation diameter of the lesion and type of bone destruction.

Great variation has been found in sagittal condylar inclination (SCI) values among individuals with different skeletal structures. Therefore, average value articulators cannot fully represent the physiological characteristics of the mandible, or reproduce its sagittal movements. The purpose of this study was to measure the SCI value of skeletal Class II patients by two different three-dimensional assessments, and to evaluate the correlation and consistency between the two methods. A total of 23 patients (aged 15–65 years) diagnosed with skeletal Class II malocclusion were recruited from the Stomatological Center of Shunde Hospital, Southern Medical University. Subjects were divided into three groups based on different A point–nasion–B point angle (ANB), and angle between the upper central incisor and Frankfort horizontal plane (U1-FH). Bilateral SCI values were measured using computer-aided diagnosis axiography (CADIAX) and cone-beam computed tomography (CBCT). Statistical analysis showed that the SCI value measured by CADIAX was significantly higher than that measured by CBCT. Significant differences were found among different ANB and U1-FH groups, and the average value of the [Formula: see text] group was the highest. Our findings indicate that the measurement of SCI by CADIAX cannot be replaced by CBCT, and it is recommended that personalized measurements of SCI values in skeletal class II patients be carried out. Individual SCI measurement can help coordinate the physiological characteristics of patients in dental treatment, benefit the health of temporomandibular joint and improve the long-term outcome. Our results suggest that the SCI values obtained by CBCT is different from the real SCI values of patients, and we will look for a simpler and more accurate clinical method to measure SCI value in future research.

Periapical Cyst

Adenomatoid odontogenic tumor (AOT) is a rare noninvasive odontogenic tumor that occurs mostly in the second decade of life. Based on its tooth association, AOT can be classified into three categories of follicular, extrafollicular, and peripheral types; the follicular classification is considered as the most common type of AOT. This study reported a large extrafollicular case of AOT in a 40-year-old female. She was asymptomatic and tumor was detected accidentally by her dental practitioner. Since the panoramic radiograph showed a well-defined unilocular radiolucent lesion, we observed radiopaque spots within the lesion by using cone beam computed tomography. The extrafollicular type can mimic a periapical radiolucent lesion.
