The longevity of pediatric dental restorations was largely influenced by surface roughness and marginal sealing. While fluoridated dentifrices aid in caries prevention, concerns about their acidic pH and additives in young children have prompted the use of nonfluoridated alternatives such as nano-hydroxyapatite, NovaMin, and calcium sucrose phosphate. These agents offer biomimetic remineralization without fluoride-associated risks. This
Materials and Methods:
One hundred twenty extracted human teeth were randomly assigned to three groups restored with Type II GIC, Type IX GIC, and nano-filled composite, then subdivided and exposed to four dentifrices: Acclaim (nano-hydroxyapatite), Vantej (NovaMin), Toothmin (calcium sucrose phosphate), and Kidodent (fluoridated control group). Surface roughness was measured using a Mitutoyo SJ-210 surface profilometer, and microleakage was evaluated by rhodamine B dye under a 40× stereomicroscope. ANOVA and Tukey’s
Results:
NovaMin showed maximum surface roughness reduction in Type IX GIC (0.26715 ± 0.03,
Conclusion:
Nonfluoridated dentifrices, especially NovaMin and nano-hydroxyapatite, effectively enhanced surface smoothness of restorative materials but had a limited influence on microleakage.
