Aim of the study: Retention is an important and necessary step at the end of orthodontic treatments. Unfortunately, periodontal inflammation and gingival retraction due to plaque deposits are more difficult to control in case of orthodontic retainers’ wearers. Material and method: Our study was performed on 87 adult patients with various orthodontic retainers. To quantitatively determine the accumulation of dental plaque we used the Oral Simplified Hygiene Index OHI-S, the Quingley-Hein plaque index modified by Turesky and the Navy plaque index modified by Rustogi. Another studied parameter was the gingival recession. Results: The results showed that periodontal problems occured most often in case of male patients wearing fixed retainers and plaque accumulation is smaller in mobile retainer wearers; the exception was for the Hawley plate, where the accumulation of interdental plaque was higher than in all the other studied retainers. Conclusions: Periodontal damage occurs most often in case of male patients wearing a fixed retainer, the use of Hawley plate resulted in the highest accumulation of interdental plaque of all studied retainers.
