Morphological evaluation of the incisive canal with reference to gender and age: A cone-beam computed tomography study

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.

Objective: To evaluate the dimensions of the nasopalatine canal (NPC) and its relationship with the maxillary central incisors (MCI) using cone-beam computed tomography (CBCT) and to determine variations in the NPC in relation to age and gender. Methods: CBCT scans from 333 patients (67% female; 35.9 ± 14.6 years) were included. The CBCT scan was analyzed to determine the length and diameter of the NPC, the distance between the NPC and the MCI, and to evaluate the morphology of the NPC. The data were analyzed using the independent Student's t-test, the Mann–Whitney and Kruskal–Wallis tests, and Dunn's post-test (p < 0.05). Results: The average diameter and length of the NPC were 2.92 ± 0.91 mm and 12.67 ± 3.32 mm, respectively. The minimum and maximum distance between the MCI and the NPC were 0.78 ± 0.42 mm and 2.56 ± 1.38 mm, respectively. The NPC of male patients was greater in length compared with the female patients (p < 0.05). The majority presented a funnel-like morphology (34.1%), followed by a cylindrical morphology (27.5%). Conclusions: There was variability in the dimensions of the NPC and its relationship with the MCI, which was influenced by gender and age.
