Abstract

Aim: To evaluate and compare resin infiltration (RI) and pit and fissure sealants on demineralized caries lesions with respect to the change in microhardness and surface roughness of lesions. Materials and methods: A total of 36 human-extracted premolars were used to create artificial demineralized lesions in enamel using the demineralizing solution. A total of 12 samples in each group was treated with respective materials—group I: nonfluoridated pit and fissure sealant; group II: RI; and group III: fluoridated pit and fissure sealants. Six samples in each group were subdivided for surface roughness and microhardness assessments using a digital surface roughness tester and a microhardness tester, respectively. The normality of the data was checked by Shapiro–Wilk test. Inferential statistics were performed using a one-way analysis of variance (ANOVA). Results: The value of microhardness for group I was 275.6 Vickers hardness number (VHN), group II 315.5 VHN, and group III 213.1 VHN, the same being statistically significant. The surface roughness values for group I was 0.377 μm, group II 0.296 μm, and group III 0.434 μm, the same being statistically significant. Conclusion: Group II showed the highest microhardness, followed by groups I and III, the same being statistically significant. Group II showed minimum surface roughness, followed by groups I and III with highest surface roughness, the same being statistically significant. Clinical significance: Resin infiltration (RI) and fissure sealants allow clinicians to manage early carious lesions with minimal invasion. These simple techniques are easy to acquire and practice for dentists and dental auxiliaries too. When used judiciously, these techniques can minimize the extensive and expensive treatment needs later.
