Type: article
Study design: Observational Study
Abstract: Objectives: , its anatomical variations, and the relationship between its opening sites and the anterior teeth in the Lithuanian population. Material and Methods: (CS) presence, distribution, opening diameter, and distances to surrounding anatomical landmarks were measured and compared by side, sex, and age groups using CS 3D Imaging software (Carestream Inc.). Results: Among 200 CBCT scans, CS was identified in 73% of subjects (365 canals), with bilateral presentation in 63% and predominantly palatal openings (96.7%). Most canals measured < 1 mm (88.7%) and median CS diameter was significantly greater on the right than on the left (0.78 [SD] vs. 0.7 [SD] mm; P = 0.034). Males exhibited significantly larger CS diameters and greater CS-nasal cavity floor and CS-buccal cortical bone distances bilaterally (P < 0.05). CS was most frequently located in the central and lateral incisor regions. No significant association was observed between CS location and sex or between age groups and CS dimensions or location; however, unilateral occurrence was more frequent in the age group of 18 to 30 years (P = 0.002). Conclusions: is a frequent anatomical structure in the anterior maxilla, most often presenting bilaterally with palatal openings. Sex-related differences were observed, whereas age showed no significant effect on canal dimensions.
