  5. 9. Nocturnal enuresis and rapid maxillary expansion : – long-term effect, prognostic variables, respiration during sleep and quality of life

    Författare :Ingrid Jönson Ring; Bazargani Farhan; Tryggve Nevéus; Agneta Markström; Maria Ransjö; Uppsala universitet; []
    Nyckelord :Rapid maxillary expansion; nocturnal enuresis; sleep disordered breathing; respiration; polygraphic sleep recording; quality of life.; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Background:The orthodontic technique rapid maxillary expansion (RME) has been reported to have a potentially curative effect on nocturnal enuresis (NE). The mechanism behind this is unknown but could possibly be due to placebo and/or effects on respiration during sleep. LÄS MER
