Background. The aim of the work is to study the morphological features and individual variability of the incisal canal, nasal and incisal openings in the first adulthood.
Materials and methods. The object of the study was 174 adults of both sexes aged 21–35 years. We studied the parameters of the craniofacial complex, the size and shape of the nasal and incisal openings, the incisal canal.
Results. It is established that the incisal canal, the nasal and incisal openings of the incisal canal have a pronounced individual variability in size, shape and topography. The incisal canal can open into the nasal cavity with one, two, three or four Stensen openings; in the oral cavity - one, two or three incisal holes.
Conclusion. The values of mesio-distal and vestibular-lingual diameters of the incisal and nasal orifices are statistically significantly higher in males. Three forms of the incisal opening were identified: heart-shaped (32.18 %), drop-shaped (28.73 %) and oval (39.08 %). Bone density in the incisal area is significantly higher in females. The length of the incisal canal prevailed in males. Most often the incisal canal had a funnel-shaped and hourglass shape, the spindle-shaped and cylindrical shapes of the incisal canal were detected relatively rarely. In most cases, the incisal canal was of the type with branches of the first order and second order, less often of all was the type of the channel with branches of the third order identified.
