Aim: To evaluate the penetration depth, surface roughness, and color stability of resin infiltration restoration of artificial enamel lesions induced in primary and permanent teeth. Materials and methods: Primary (group I, n = 30) and permanent (group II, n = 30) extracted non-carious human anterior teeth were subjected to demineralization for four days after creating a window of 5 mm × 5 mm on the labial surfaces. Demineralized area was infiltrated with the low viscosity resin. Ten samples from each group were evaluated for penetration depth, surface roughness, and color stability, respectively. Penetration depth was determined using a stereomicroscope at 80× magnification. Surface roughness of sound and infiltrated enamel was recorded using a profilometer. The color stability was assessed at 2, 4, and 8 weeks along with baseline values using vita easy shade spectrophotometer. Results: Data were analyzed using the student “t” test and Friedman test. The degree of resin penetration was observed to be higher in primary teeth (32.6 ± 15.72 μm) compared to permanent teeth (24.23 ± 6.85 μm), but no significant difference was found (p = 0.138). Surface roughness values of resin infiltrated enamel is similar to that of sound enamel in both primary (p = 0.617) and permanent teeth (p = 0.234). The mean color stability scores immediately after resin infiltration at 2, 4, and 8 weeks intervals showed no statistically significant difference in primary (p = 0.998) and permanent teeth (p = 0.213). Conclusion: Resin penetration into enamel lesions was more in primary teeth enamel compared to permanent. The early enamel lesions, when treated with resin infiltration, showed surface characteristics similar to sound enamel and also exhibited acceptable color up to 8 weeks duration. Clinical significance: Resin infiltration can be considered as an effective and predictable treatment option for the restoration of early enamel lesions owing to its deeper penetration, provision of better surface characteristics, and reliable masking of white spot lesions in both primary and permanent dentitions.
