Clinical Studies

This article describes the clinical case of a patient, a 13-year-old boy, in whom the appearance of patent nasopalatine ducts was noted after having a rapid maxillary expansion performed. To confirm this finding, inspection and radiographic examination were performed in which gutta-percha cones were used as contrast. The patient related no symptoms or discomfort due to the ducts. The patient was followed up for a period of 6 months, during which he was instructed as regards correct cleaning to prevent the accumulation of food and infection.
