Impacted canines are the second most common (after the third molars) impacted teeth. Good diagnostics for impacted canines is possible at approx. 10 years of age, when the incorrect angulation of the crown of the tooth can be seen on the panoramic X-ray. The initial assessment of impacted canines includes a basic dental examination (presence of persistent deciduous teeth, lack of erupted permanent canines in the dental arch after the end of tooth eruption) and a palpative examination of alveolar bone in the vestibulum. The diagnostics is based mainly on X-rays: mainly panoramic images, tooth X-rays and occlusal plate pictures. The new tool in the diagnostics of impacted teeth is computed tomography, especially CBCT. The study collates diagnostic methods based primarily on panoramic X-ray images for the assessment and prediction of the spontaneous eruption chances of maxillary canines.

Key words: impacted canine, diagnostics.
