“…This therapeutic effect was lower than in previous studies. [1][2][3][4][5][6] The study reporting the highest therapeutic benefit was the work of Al Taai et al 4 That study, however, reported the enuresis frequency in the number of enuresis episodes per night instead of number of wet nights per week, which makes it difficult to compare. A previous metaanalysis of six articles showed that the average rate of becoming completely dry 1 year after RME was 31%.…”

“…21 Our previous study also indicated a higher response: 60%. 5 The sample in the present study was composed of mainly therapy-resistant children with a high enuresis frequency. This may partly explain why there was a lower full response rate than in the earlier studies.…”

“…This may partly explain why there was a lower full response rate than in the earlier studies. [1][2][3][4][5][6] Another reason may be that there was a shorter follow-up time used in order to limit the effect of spontaneous resolution, which is approximately 15% per year. 22 Most previous studies had a longer follow-up time than the current study, and it is quite likely that some spontaneous resolution occurred during the observation time.…”

“…The reduction of wet nights for the placebo group was minimal and, as in previous studies, the current study did not find a positive placebo effect of the appliance. 4,5 A large average daytime voided volume and a wide maxilla may be associated with an increased chance of having the enuresis frequency reduced, and these two variables seemed to be of favorable prognostic value. The association between voided volume and a favorable outcome of the RME treatment is worth mentioning, even though it was not statistically significant.…”

“…Rapid maxillary expansion (RME) has previously been reported to have a potentially curative effect on nocturnal enuresis (NE) or bedwetting. [1][2][3][4][5][6] The term nocturnal enuresis is used for involuntary voiding of urine at night in children aged 5 years or older. 7 After asthma and allergies, NE is the most common health problem in school children, affecting about 10% of 7year-olds.…”

Objective: To investigate whether rapid maxillary expansion (RME) is a useful treatment method for nocturnal enuresis (NE) and whether the treatment effect is due to placebo. The study also aimed to identify prognostic variables in patients responding to treatment. Materials and Methods: Thirty-eight children with therapy-resistant NE were recruited and randomized into two groups: the intervention group or placebo group. Both groups were treated with RME, but the placebo group received treatment with a sham appliance for 2 weeks before having the actual treatment. A medical history focused on micturition habits, previous treatment, heredity, and sleep disorders was taken. Daytime voided volumes and nocturnal urine production during wet nights were recorded before the intervention. Results: Of the 38 patients recruited, two dropped out as one patient was unable to take dental impressions and one refused to have the appliance fitted. There was a statistically significant reduction of wet nights after the RME treatment (P < .001). No significant reduction was found after the placebo treatment (P < .40). Eleven patients (35%) had their enuresis frequency reduced by >50%. Large voiding volume and a wide maxilla at baseline had a strong association with positive treatment outcome. Conclusions: RME has a modest effect on children with therapy-resistant NE. The treatment outcome does not seem to be due to a placebo effect of the appliance. A wide maxillary width and large voiding volume at baseline seem to be positive predictors regarding response to treatment.
