| Abstract | ||
| Aim: To evaluate the effect of 45S5 bioglass nanoparticles versus Er:YAG 2940 nm laser, either alone or in combination, on dentin and dentinal tubule occlusion. Materials and Methods: Forty dentin discs were used for this study. All dentin discs were soaked in 1% citric acid and after that distributed equally into four groups. Group (1): received no treatment, only desensitization. Group (2): treated with bioglass nanoparticles alone. Group (3): treated with Er:YAG laser irradiation only. Group (4): treated with bioglass after Er:YAG laser irradiation. Dentin samples were morphologically assessed by scanning electron microscopy, and elemental analysis was carried out using energy dispersive X-ray analysis. Results: Compared with other groups, the combined group demonstrated noticeably better dentinal tubule closure, as verified by SEM imaging. The EDX analysis, which revealed the greatest calcium and phosphorus mass percentages in the combined group, validated these results. Conclusion: Dentinal tubule closure was deemed satisfactory with the use of bioglass and an Er:YAG laser. However, rather than employing each modality alone, it was discovered that combining bioglass and a laser produced better results and was more efficient. | ||
