[Age-related characteristics and sex differences in the anatomical structure of the incisive canal].
Age- and sex-associated features in the anatomy of the incisor canal were studied in 254 human skulls aged 22 to 70 with orthognathic intact occlusion and in 66 maxillofacial saw cuts with the use of craniometric and statistical methods of investigation. The findings evidenced age- and sex-linked differences in the mean length of the incisor canal and its openings in mature age. The incisor canal is situated near the central incisor root apexes, the mean distance being 7.4 +/- 0.1 mm. The incisor opening is situated on the lower surface of the maxillary palatal process along the median line at a distance of 9.8 +/- 0.2 mm from the point formed by the medial angles of the central incisor crowns, irrespective of the subject's sex. The distance between the incisor opening and the central incisor roots in adults is 3.5 +/- 0.1 mm.
