[Clinical studies for the evaluation of the composite filling material Evicrol].

339 Evicrol fillings were clinically re-examined 0,52 to 2 years after insertion. The comparison of the results obtained with those from silicate cement fillings (Hildisch) evidenced that the properties of Evicrol are better. In assessing Evicrol for a prolonged period, special attention must be paid to the higher percentage (18--33%) of discolourations appearing already within 1--2 years.
