Methods: Twenty-two patients having two contralateral deep occlusal carious molars with no signs of pulpal inflammation were recruited. The 44 cavities were prepared with partial caries excavation technique. Where, in group A; 0.2 ml of NSF solution was applied in the cavity and agitated for 2 minutes prior to the restoration. While, for group B; Glass ionomer (Equia forte) was directly applied into the cavity. Standardized digital periapical radiographs were taken at baseline and after 6 months. The carious dentin density and the dentin bridge formation were calculated using Digora for Windows (DFW) 2.5 software program. Comparison between the study groups was done using Mann Whitney U test for independent samples. Within group comparison between baseline and 6 months values was done using Wilcoxon Signed Rank test for paired samples. Results: Statistically significant increase of both the dentin density and the dentin bridge thickness was found for both groups after 6 months compared to baseline (p=0.001). However, the percentage change in the density after 6 months was significantly higher for group A that reached more than double that of group B (p= 0.008). While, no differences were found between both groups in the dentin bridge thickness (p= 0.885). Conclusions: Partial caries excavation for deep carious lesions showed significant remineralization of carious dentin and increase in dentin bridge thickness. Furthermore, NSF solution noted to be a promising agent helping in caries arrest.
