Mean ± standard deviation (sd), 95% confidence interval (CI) of hardness at baseline (HB), hardness upon acid-activated demineralization (HD), hardness after application of remineralizing agent (HA), hardness difference determined between after acid-activated demineralization and after application of remineralizing agents (HAD-diff = HA − HD), percentage of hardness recovery (%HR) of each group after application of remineralizing agents (HA) in comparison to after acid-activated demineralization (HD), and average crystal size for each treatment group.
