Background. The etiology of nocturnal enuresis (NE) is multifactorial and has not been fully explained yet. New ways of treatment are constantly being investigated, including the rapid maxillary expansion (RME). Methods. A total of 41 patients diagnosed with NE were divided into two experimental groups: A and B. Group A included 16 children who have been treated with RME. Group B comprised 25 children who have not undertaken orthodontic treatment. Children from both groups have been monitored in monthly intervals, during a 12-month period, towards the intensification of NE. The comparative analysis of both groups has been conducted after 3 years of observation. Results. Statistical analysis has shown a 4.5 times increase of the probability of reduction of NE in the case of the treated group in comparison with the group of children who have not undergone orthodontic treatment. Unfortunately, the chance of obtaining total dryness diminished proportionally to the higher degree of intensification of enuresis at the beginning of the test. Conclusion. RME can constitute an alternative method of NE treatment in children, irrespective of the occurrence of upper jaw narrowing.
