Abstract

Developing enamel was stained with pH indicators and a banded colour pattern exhibiting alternate acidic (5.8-6.0) and neutral (7.0-7.2) staining was clearly visualized. The pH values of the enamel samples scraped from respective bands were confirmed by measuring them in suspensions with a pH meter. Neutral bands corresponded to red stripes of glyoxal bis(2-hydroxyanil) staining and acidic bands to unstained ones, suggested a correlation of the acidic and neutral stripes with the zones of ruffle-ended and smooth-ended ameloblasts.
