Morphological and volumetric evaluation of the nasopalatinal canal in a Turkish population using cone-beam computed tomography

摘要

Purpose To establish (nasopalatine canal) NPC morphology and obtain linear and volumetric measurements using CBCT images. Methods We evaluated CBCT scans of 252 patients. NPC shape was classified as belonging to six groups. Following measurements were recorded: M1, nasal foramen diameter; M2, incisive foramen diameter; M3, NPC length; M4, distance from the buccal border of the incisive foramen to the facial aspect of the buccal bone plate; M5, distance from the buccal bone wall of the NPC to the facial aspect of the buccal bone plate; and M6, distance from the buccal border in the middle of the NPC to the facial aspect of the buccal bone plate. Volume and surface area measurements of the NPC were also conducted. Sex, age and maxillary anterior teeth status (MCI) were recorded. Four-way repeated ANOVA was performed. Significance level was set at p < 0.05.
