RESUMO
AIM AND OBJECTIVE: To determine and compare remineralizing efficacy of NovaMin, CPP-ACP, silver diamine fluoride (SDF), and P11-4. MATERIALS AND METHODS: Sixty permanent premolars were divided into four groups with 15 samples in each group; group I: self-assembling peptide (P11-4), group II: SDF, group III: Casein phosphopeptide-stabilized amorphous calcium phosphate (CPP-ACP), and group IV: NovaMin. Mineral content was assessed using a scanning electron microscope at 7, 14, and 21 days after remineralization with each agent. RESULTS: The mean remineralization in group I at 7 days was 1.73 ± 0.02, at 14 days was 1.79 ± 0.01, and at 21 days was 1.90±0.03. Mean remineralization in group II was 1.61 ± 0.01, 1.64 ± 0.02, and 1.73 ± 0.03 at 7, 14, and 21 days, respectively. Mean remineralization in group III was 1.62 ± 0.01, 1.65 ± 0.02, and 1.74 ± 0.05 at 7, 14, and 21 days, respectively. Mean remineralization in group IV was 1.59 ± 0.02, 1.62 ± 0.07, and 1.70 ± 0.09 at 7, 14, and 21 days, respectively. The maximum value was obtained on day 21. There was a significant difference in mean remineralization values between group I vs group II, group I vs group III, and group I vs group IV (p < 0.05). CONCLUSION: Self-assembling peptides showed maximum remineralization in tested specimens followed by CPP-ACP, SDF, and NovaMin-containing toothpaste. CLINICAL SIGNIFICANCE: CPP-ACP, SDF, and NovaMin-containing toothpaste can be indicated for remineralization of initial caries in clinical use.

Aspergillosis of the nasal and paranasal sinuses is recognized as being second to candidiasis, among opportunistic fungal infections in immunocompromised patients. However, invasive variant in normal and mildly immunocompromised hosts is a very rare occurrence. We report one such case of aspergillosis involving paranasal sinuses in mildly immunocompromised patient.
