MDCT evaluation of nasopalatine canal morphometry and variations: An analysis of 100 patients
Abstract
The goal of this study was to investigate the possible variations in morphology of nasopalatine canal (NPC) morphometry depending on age, gender and absence of anterior incisors using multidetector row computed tomography (MDCT). A total of 100 patients (50 men, 50 women) with a mean age of 43.29±18.81 (SD) years (range: 18-90 years) who have undergone head MDTC were included into the study. Foramen nasalis diameter (P1), foramen incisivum diameter (P2), NPC length (P3), distance between buccal wall of incisive foramen and facial side of the buccal bone (P4), distances between buccal bone wall of NPC and facial side of buccal bone (P5), distance between mid-NPC buccal wall and facial side of buccal bone (P6), distance between buccal wall of NPC and the apex of anterior central incisors (P7) and NPC angle (P8) were measured. Formal variations in NPC were searched for. Differences in morphometric data were searched using Student t-test or Mann-Whitney test. Gender-based analysis of the variations was done with the χ(2) test. Pearson's test was used to search for correlation between morphometric data and age. P1 was larger in men (3.72±1.41mm) than in women (3.07±1.34mm) (P<0.001). Similarly, P3 was larger in men (13.68±2.73mm) th...Continue Reading
