Evaluating Surface Microhardness in Silver Diamine Fluoride-treated Primary Dentin Post-laser Irradiation: An In Vitro Study of Three Laser Modalities
Year: 2025
Type: article
Abstract: Aim and background: laser, neodymium-doped yttrium aluminum garnet (Nd:YAG) laser, and diode laser in extracted carious primary molars. The use of different lasers in combination with fluoride has been shown to have a synergistic effect on caries prevention by increasing fluoride uptake in the enamel. Following laser treatment, fluoride is not only deposited on the enamel and dentin but is also incorporated into the enamel and dentin crystalline structure. Materials and methods: laser, group III: received SDF followed by Nd:YAG laser, group IV: received SDF followed by diode laser. Then the samples were tested for the Vickers microhardness test. The data so obtained were subjected to statistical analysis. Results: laser), group III (Nd:YAG laser), and group IV (diode laser) were 272.53 ± 13.18, 321.2 ± 3.46, 294.92 ± 25.32, and 293.64 ± 17.57, respectively. Group II exhibited the largest mean difference, with an increase of 48.67 microhardness. Conclusion: Combining silver diamine fluoride (SDF) with CO₂ laser treatment significantly increases dentin microhardness, enhancing remineralization and caries resistance. This minimally invasive approach supports CO₂ lasers as a safe, effective adjunct to SDF in pediatric dentistry. Its subablative energy preserves surrounding tissues, aligning with evidence-based, conservative treatment practices. Clinical significance: lasers minimizes the risk of thermal damage to surrounding tissues, offering a safer and more precise treatment option for sensitive areas.
