Analyzing the morphological characteristics of thenasopalatine canal in human dry skulls based onlength and shape through the application of artificialintelligence and machine learning.

Abstract

In this novel investigation, 56 dry human skulls, inclusive of both genders, underwent scrutiny to assess the dimensions and configurations of the nasopalatinecanal (NPC). The measurement of NPC length, extending from the interproximal region of the central incisors to the distal end of the incisive foramen, disclosed amean length of 17.8 mm in males and 14.2 mm in females. A noteworthy statistical distinction was evident between male and female lengths (P < 0.01). Furthermore, the diameter of the incisive foramen displayed a non-significant variation betweenmales (5.6 mm) and females (5.1 mm). Classification of nasopalatine canal shapesresulted in intriguing patterns, with cylindrical configurations prevailing in 27cases, followed by funnel shapes in 9, hourglass shapes in 20, and spindle shapes in4 skulls. The distribution of shapes exhibited statistically significant differences (P< 0.05). These findings emphasize the critical necessity of evaluating nasopalatinecanal morphology to mitigate the risk of iatrogenic injury to anatomical structures.
