[Dimensions of deciduous and permanent incisors in cases with Class II division 1 and 2 malocclusions].
The analysis of mesiodistal dimensions of the upper and lower incisors (in total and separately) has been carried out in order to investigate the interdependence of sizes of the teeth with defined malocclusions. The investigation included 180 cases of both sexes, out of which 90 had deciduous dentition and other 90 examinees had permanent dentition. There were 120 examinees with Class II malocclusion (60 with Class II/1, and 60 with Class II/2), whereas the rest of 60 examinees with normal occlusion were used as the control group. Gnathometric measurements were made on the plaster casts with calipher precision of 0.1 mm and were double checked. Computer analysis of the results obtained emphasized the following: the heterogeneity of findings in the deciduous dentition does not allow hypothesis of a connection between sizes of the deciduous incisors and defined malocclusions; in the permanent dentition the examinees with Class II division 1 malocclusion have significantly the largest incisors, and the smallest the examinees with class II division 2 malocclusion; the greatest difference in the size between the deciduous and permanent incisors was found in the examinees with Class II division 1 malocclusion and the smallest difference was found in the examinees with normal occlusion.
