Purposes:To determine the anatomical variability of the incisive canal (IC) and to clarify its characteristics, using cone beam computed tomography (CBCT) evaluation, in order to avoid intra-and post-operative complications in oral surgery. Materials and Methods:The diameter, length and angulations of the IC and the width of the bone anterior to the canal were measured on 100 digital CBCT using the Galileos Implant 1.9 software. The patients' ages ranged from 14 to 54 years (53 males and 47 females). The data were analyzed using the Stat View 5.0 software. Results:The anatomy of the IC shows a large variability in its morphology and dimensions, with the canal branching into up to four canals at the nasal level. The length of the IC varies from 4.94 mm to 26.13 mm with an average of 11.42 (±2.71) mm with a statistically significant difference between genders. The ICs were classified into 6 categories according to their shape viewed on the sagittal sections, with two new shapes found. The incisive foramen has four shapes with a statistical correlation with the gender of the subject. The bone thickness anterior to the canal shows a statistical correlation with the gender of the subject and the presence or absence of the central incisor. Conclusions:The present study highlights an important variability in the anatomy and morphology of the IC. Therefore, a CBCT analysis of this structure is essential to avoid any complications before any surgery in this area.

“…In the literature, the status of the central incisors significantly influences the length of the IC [11,13]. It was also previously reported that the period of the incisor loss statistically influences the IC length [11,13,14].…”

“…Although remodeling of the incisive canal following orthodontic tooth movement has not, to our knowledge, been reported, 25 relative changes in the position of the incisive canal because of changes in the surrounding alveolar bone following tooth loss have been noted in the edentulous dentition. 22,38 Therefore, to determine the remodeling potential of the incisive canal wall following orthodontic tooth movement, further evaluations using comparisons of pre-and posttreatment materials are necessary. Mean values with the same superscript letters within a row are not significantly different from each other.…”

Objective: To evaluate the morphologic features and the relative position of the incisive canal with regard to the maxillary incisor roots using computed tomography (CT). Materials and Methods: Morphologic evaluation of the incisive canal and its proximity to the maxillary central incisors were measured using CT images of 38 adults with skeletal and dental class I normal occlusion. Linear measurements were performed on the axial cross-sectional images corresponding to three vertical levels, the palatal opening of the incisive canal (L1), midlevel between the opening level and the root apex of the maxillary central incisors (L2), and the root apex of the maxillary central incisors (L3). Results: The percentage of subjects with an incisive canal width greater than the interroot distance of the central incisors was 86.8% and 63.2% at levels L1 and L2, respectively. The anteroposterior distance between the maxillary incisor roots and the boarder of the incisive canal was approximately 5-6 mm at levels L1 and L2. Conclusion: The anteroposterior distance between the maxillary central incisor roots and the incisive canal was approximately 5-6 mm. More than 60% of the subjects had an incisive canal width greater than the interroot distance. Evaluation of the proximity of the incisive canal to the maxillary incisors, along with its dimensional characteristics, may be helpful when a considerable amount of maxillary retraction is planned.

“…Нами также не выявлено признаков неврита: больные не отмечали боли в области дна носа, переднего отдела твердого неба, иррадиации болей. Мы считаем, что травмирование резцового нерва безусловно возни-кает при проведении резцовой проводниковой ане-стезии, однако оно минимально в связи с тем, что резцовый канал содержит в себе, помимо нервных структур, сосуды, жировую ткань, соединительную ткань, малые слюнные железы [12]. При медленном введении анестетика (1 мл/мин) его распределение происходит постепенно без выраженной компрес-сии нервных структур, что подтверждается отсут-ствием постинъекционных неврологических ослож-нений у наших пациентов.…”
