[Changes in the physical properties of Gingivamoll flexible gingival epithesis].
It was the purpose of this study to investigate variations in weight, volume, hardness, material density, adjustment and colour of Gingivamoll flexible gingival masks during a period of twelve months. Additionally, patients were inspected for potential infections of Candida albicans. Thirty-three gingival masks of nine patients were selected for the study. One third was placed into patients' mouths, one third was placed on stone models under room conditions and a third group was submerged under water. At baseline all gingival masks were examined and measured. For the first half of the year, measurements were recorded monthly and in the second half of the year at two months' intervals. Results showed a constant Shore-A hardness, volume and density. Gingival masks submerged under water kept their weight. The other masks, i. e. those placed into patients' mouths and those placed on plaster models, lost weight. Adjustment deteriorated at distal sites. Colour stability was not satisfactory. Tests for Candida albicans remained negative. It can be concluded that Gingivamoll flexible gingival masks can be used without serious problems for a period of twelve months.
