Research objective. The study aimed to evaluate cone-beam computed tomography (CBCT) capabilities in diagnostics of cystic masses of the jaw.Methods. Over a period of 2015–2016 32 patients age 6 to 67 underwent both panoramic tomography and CBCT (using panoramic tomographic scanner STRATO 2000 and cone-beam computed tomographic scanner i-Cat respectively). 47% (n = 15) of the participants were women, 53% (n = 17) – men. Radiation exposure for a single procedure amounts to 0,05 mSv for panoramic tomography, 0,07 mSv for CBCT (FOV =13 cm), 0,06 mSv for CBCT (FOV =8 cm).Results. Comparative analysis of obtained results demonstrates that CBCT showed 54% (n = 27) more cystic masses of the jaws than panoramic radiography could. CBCT additionally showed the following pathologies: granulomas smaller than4 mm diameter – 85% (n = 23), 83% (n = 23) of said granulomas were found on maxilla, radicular cysts of maxilla – 11% (n = 3), incisive canal cyst – 4% (n = 1). Additionally panoramic tomography analysis misdiagnosed 5 granulomas (80% (n = 4) on mandibular premolar and molar areas) that were not found during CBCT analysis.Conclusion. The low effective dose and high informativity of CBCT enables the method to be used instead of intraoral radiography, panoramic tomography and MSCT as a screening procedure in diagnostics of dento-facial system pathologies, including cystic masses of the jaw.

Inferior Alveolar Nerve Injury

BACKGROUND A serious complication of surgical removal of impacted lower third molars is inferior alveolar nerve (IAN) injury. Evaluation of radiographic factors to predict IAN injury using CT and panoramic radiography includes root morphology assessment, follicular sac size, mandibular bone density, inferior alveolar nerve and vessels, condition of the overlying tissues, relation of the impacted tooth with the body and ramus of the mandible and the adjacent teeth. This study was done to evaluate the radiological features of the impacted lower mandibular teeth and their relationship with IAN through panoramic radiography and CT and to assess the most predictable radiological criteria for inferior alveolar nerve injury in impacted third molar surgery. METHODS All the patients indicated for lower third molar extraction were included in the study and pre-operative conventional panoramic radiographs (Planmeca Proline PM 2002 CC, Helsinki, Finland) and CBCT (Kodak CBCT) were taken. Any post-operative nerve injuries detected were followed up after 15 days or 1 month. Fisher’s exact test was done to find the association between the outcome variable and explanatory variables. RESULTS Only 11.4 % (N = 4) of all participants had IAN injury following surgical disimpaction. All the participants with IAN injury showed narrowing of the canal on their preoperative panoramic radiographs and presence of nerve approximation with the tooth in cone beam computed tomography (CBCT) reports (P < 0.05). CONCLUSIONS A statistically significant association exists between IAN injury and nerve exposure, radiographic signs of nerve involvement for panoramic radiograph, level of third molar impaction, and nerve approximation in CBCT.
