The aim of the study was to determine the influence of age on the location of the maxillary mucogíngíval junction. The material comprised orthopantomograms of 20 male and 20 female students aged 21–30 years and 20 male and 20 female adults aged 39–51 years. The mucogingival junction was revealed with Schiller's iodine solution and marked with short pieces of metal wire, attached to the teeth and gingivae with Squibb's Orahesive Dental Bandage in the midline of the facial surface of ech ototh. Orthopantomograms were taken to the marked dentitions with the X‐ray beam passing the horizontally positioned occlusal level at a –5° angle. From the radiographs the distance from the floor of the nasal cavity to the mucogingival junction was measured separately for each tooth to the nearest millimeter. The distance between the floor of the nasal cavity and the mucogingival junction was found to be the same in both age groups. Since thre is no reasons to believe that the floor of the nasal cavity would move downwards and certainly not upwards with advancing age, it was suggested that the mucogingival junction also remains at a constant location through adult life.
