| Description | Aim: The aim of the retrospective study was to analyze the relationship between the dental arches expressed by Angle classes in patients with eruption disturbances of the maxillary permanent canines. Material and methods: This retrospective study comprised 871 consecutive Caucasian orthodontic patients. The control group consisted of 603 subjects (376 females and 227 males) with physiologically erupted permanent maxillary canines. The palatally displaced canines group included 226 patients: 146 females and 80 males. The buccally displaced canines group comprised 42 patients: 18 females and 24 males. Results: In the set of 871 orthodontic patients, Angle Class I occurred in 45.4 %, Class II in 51.5 % (division 1 in 13.3 %, division 2 in 27.2 % and without division in 11 %) and Class III in 3.1 %. Stat. significant differences in frequencies of Angle Classes between the control and the set of patients with PDC (P=0.00001) and between the sets with PDC and BDC (P=0.015) were found. In the sets of patients with ectopic. erupting canines, significantly higher occurrence of Class II division 2 was not determined, but stat. significantly higher occurrence of Class I was found (P=0.000001). Conclusion: Retrusion of the maxillary incisors can be considered a more important factor relating to PDC than a type of the Angle Class. |
