[Study on the interrelation between dysplasias of permanent teeth and dental-jaw deformities. 1. Clinical-statistical study on the incidence and type of dental-jaw deformities among students with dysplasia of the permanent teeth].
A total of 125 students, aged from 6 to 18, with dysplasia of the permanent teeth were examined by a qualified pediatric stomatologist and orthodontist. Dental-jaw deformities (DJD) were established in 74.40% of all examined students. Most frequent proved to be the combination of DJD with hypomineralization in mixed dentition (34.41%) and with hypoplasia in permanent dentition--20.45% and hypomineralization--10.75%. The analysis with a view to the type of DJD revealed that the combination between dysplasias of the permanent teeth and deformities in the proportion of the jaws was most frequent (56.84%). The highest relative share of deep bite was established (27.89%) with no tendency to selfregulation in the permanent dentition. The authors underlined the necessity of follow-up care of the students with dysplasia in combination with DJD in connection with the joint therapeutic and orthodontic treatment.
