Abstract
Objectives:
This study aimed to examine the remineralizing effects of Miswak and amorphous calcium phosphate fluoride/casein phosphopeptide (MI paste plus) in treating artificially induced white spot lesions (WSL) following chemical or laser-assisted bleaching.
Materials and Methods:
premolars , resulting in forty specimens by immersing them in a freshly prepared demineralizing solution for 96 hours. An investigation using a scanning electron microscope (SEM) and energy-dispersive X-ray (EDX) elemental analysis was conducted. Twenty specimens were subjected to chemical bleaching using 36% hydrogen peroxide for a duration of 10 minutes. The remaining 20 teeth underwent bleaching with 36% hydrogen peroxide, triggered by a diode laser for 90 seconds over three treatments, interspersed with 60-second rest intervals. The evaluated remineralizing agents (Miswak and MI Paste Plus) were used either before to or after to bleaching. In the end, an additional SEM/EDX record was evaluated. The data were examined utilising the Kruskal-Wallis test, succeeded by Dunn’s post hoc test with Bonferroni correction for intergroup comparisons.
Results:
In treated specimens, Miswak was equivalent to MI paste plus for the enhancement of calcium and phosphate percentages, with no significant difference noted. The laser-assisted bleaching groups exhibited a significant rise in calcium percentage compared with the chemical bleaching groups. The pre-bleaching remineralizing groups exhibited a less significant rise in calcium and phosphate percentages compared to the post-bleaching groups.
Conclusions: Both Miswak and MIpaste Plus can remineralise white spot lesions (WSL) following bleaching; however, laser-assisted bleaching is more effective and safer than chemical bleaching for remineralization of WSL.
