摘要

FIELD: medicine.;SUBSTANCE: diagnostic technique for initial dental caries consists in applying 1% Rodamin C fluorescent dye on a segment of the changed dental tissues after tartar removal, and fixing the dye for 1-3 min, rubbing the dye simultaneously with a microapplicator; the excessive dye is washed off with water; the moisture is removed; the dye is developed by means of a dental polymerisation lamp, and the presence of red colour visualised through an orange ophthalmic filter shows initial caries.;EFFECT: using the technique enables the reliable detection of initial caries in a relatively short time without the need of using special instruments.;2 ex, 4 dwg
