Table 3.

Mean values (standard deviation) of QLF for tested areas, ΔF₀ (sound vs.demineralized area) and ΔF₁ (soundXtreated area) in the experimentalgroups

Product	ΔF₀	ΔF₁
NC	− 27.8 (2.3)^a	− 34.8 (2.2)^C
PC	− 29.9 (2.4)^a	− 24.1 (2.3)^B
RDC	− 25.4 (7.8)^a	− 13.5 (5.6)^A
RES	− 26.4 (9.8)^a	− 21.3 (11.8)^B
SRP	− 29.8 (6.3)^a	− 29.5 (6.6)^B

Means followed by distinct letters, lower case for ΔF₀, upper cases for ΔF₁: significant, p < 0.05
