title: [Clinical evaluation of the quality of amalgam and polymer filling materials after various periods of function. A study of servicemen of the German armed forces].
abstract: A total of 354 amalgam and 123 polymer fillings in 50 soldiers were subjected to a post-treatment evaluation to obtain information on the life of plastic fillings. This study was performed using a simplified procedure based on the evaluation of margins, anatomic design, surface condition as well as (in polymer fillings) color. 45.5% of the single-surface and 67.9% of the multisurface amalgam fillings as well as 53% of the polymer fillings were in need of remaking. The quality of the fillings decreased with increasing age. Thus, only 12% of the newer (less than 4 years) but 30.8% of the older (greater than 4 years) amalgam fillings had the poorest ratings.
