J. Ruben et J. Arends, SHRINKAGE PREVENTION OF IN-VITRO DEMINERALIZED HUMAN DENTIN IN TRANSVERSAL MICRORADIOGRAPHY, Caries research, 27(4), 1993, pp. 262-265
The shrinkage of demineralized dentine is a serious problem in the ass
essment of mineral distributions and mineral changes by means of micro
radiography. In this article it is shown that a treatment with ethaned
iol of the thin slices used for transversal microradiography prevents
shrinkage for about 1 h. Without this so-called diol treatment, the sh
rinkage effects in demineralized dentin are about 20% in lesion depth
and about 30% in mineral loss (DELTAZ) after 120-second drying in air.
The prevention of shrinkage by diol treatment of dentine lesions is n
ot influenced by the presence of a surface layer.
