... 32.4 ± 6.0 and 17.1 ± 4.2 mM calcium after 1 and 5 min, respectively. Calculations showed that the plaque was saturated with respect to enamel during the first 5–10 minutes after food ingestion, in spite of the progressive drop in plaque pH. In conclusion, the present study demonstrated the reduction...

... after the 5% sucrose rinses, then fell; Pi reached a stable level of 12.2 ± 2.3 mEq/1 by 60 min. Calculations showed that conditions approached saturation with respect to enamel and dicalcium phosphate dihydrate as demineralization reached a maximum. Demineralization appeared to be limited at low plaque...

...H.M. Theuns; F.C.M. Driessens; J.W.E. van Dijk Sound human premolars were cut transversely and polished. The polished surface of the buccal enamel was exposed to buffer solutions of different degrees of saturation with respect to hydroxyapatite. The mineral content of the surface layers...

...J.M. ten Cate; P.P.E. Duijsters In this paper, the demineralization of dental enamel was studied in under-saturated calcium phosphate solutions with different pH and fluoride concentrations. The combined data of the mineral dissolved show a dissolution pattern not significantly different from...

... in relative saturations with respect to different calcium phosphates. Differences in area:solution ratios and baseline Zmax values may also have explained the different response to PF. Low-R lesions were similar to natural white-spot lesions in terms of mineral distribution, whereas high-R were...

... or infinitely undersaturated. In the partially saturated systems, calcium and phosphate concentrations were representative of plaque fluid. In the first study, demineralisation of enamel next to one dentine block was reduced in inverse proportion to the distance from the dentine. Demineralisation of enamel...
