The condition of the parodontium was studied in 281 children. Group I comprised children with malocclusion treated by maxillary orthopaedic methods, group II--children with non-treated malocclusion, group III--children with normal occlusion. The condition of the parodontium was assessed in various types of malocclusion, in groups of teeth and in relation to the duration of treatment with maxillary-orthopaedic devices. The parodontium was evaluated using the indices GI and PMA. The highest prevalence of parodontitis was found in cases of isolated crowding of teeth. Changes were observed, most frequently, at the lower incisors. With time of device use the values of the GI and PMA indices increased to a peak value in the 2nd year of the treatment, while past that time these values fell.
