Why the study?
Do different plaque disclosants (erythrosine, fast green, sodium fluorescein, normal saline) differ in their effect on plaque score, plaque weight, and EDTA dispersion?

Supports interchangeable use of the four disclosants in practice; confirms their equivalence on plaque metrics.
Do different plaque disclosants (erythrosine, fast green, sodium fluorescein, normal saline) differ in their effect on plaque score, plaque weight, and EDTA dispersion?
The tested plaque disclosants did not significantly differ in their effects on plaque indices, and the low correlation between indices suggests they measure different aspects of plaque accumulation.
Varma et al. (1974) studied this question.
