This *in vitro* study compared the remineralization efficacy of a hydroxyapatite-based gel (15% HAP) applied daily and a high-fluoride (12,500 ppm F) gel applied weekly on initial caries lesions, using artificial saliva as a control. Both gels showed significant remineralization (*p* < 0.0001), with no significant difference between them. Both gels were significantly more effective than artificial saliva alone (*p* < 0.001). The hydroxyapatite gel demonstrated homogenous remineralization across the lesion, while the fluoride gel's effect was limited to the surface zone. The study concludes that 15% HAP gel is as effective as the high-fluoride gel in remineralizing initial caries lesions.
