title: [Calcium-containing incrustations on IUD's--detection using electron scanning microscopy].
abstract: On the surfaces of intrauterine contraceptive devices the occurrence of incrustations has been noticed, which presented blade or needle crystal structure on electron microscopic scanning exposures. In conformity with earlier findings, these products showed the character of calcium compounds. Attention is called to the significant part that such an incrustation is likely to play in the rise of complications and harmful side effects.
