Abstract
Treatments that obdurate dentin tubules have been used for reducing dentin hypersensitivity. The objective of this study was to determine the effects of multiple treatments with a mildly supersaturated calcium phosphate solution on the hydraulic conductance (Lp) of partially occluded dentin discs in vitro. The treatment solution contained 6.5 mmol/L (mM) each of calcium and phosphate, 0.25 mM fluoride, 30 mM KCl, and 50 mM HEPES buffer (pH adjusted to 7.0). The mean baseline Lp (in L cm-2 min-1 H2O cm-1) was 0.108 0.041 (mean s.d.; n = 9), and after five consecutive treatments, the mean relative Lp, presented as % of baseline, were 71 11, 58 10, 46 18, 40 14, and 25 10, respectively. The Lp values of the baseline and treatment groups were significantly (pCitation
