Abstract

Objective To investigate the effect of CPP-ACP and Novamin on citric acid erosion resistance of pellicle-covered enamel. Materials and methods Thirty-six human enamel samples, 2 x 2 x 2 mm3 in size, were covered by pellicle from storing in oral cavity of one healthy volunteer for 2 hours. Subsequently, enamel samples were divided into 3 groups (each group n = 12); control, CPP-ACP and Novamin groups. CPP-ACP or Novamin was applied on enamel surfaces for 3 minutes then rinsed with de-ionized water. Then, all samples were immersed in 1 ml of citric acid (1%) for 60 s. Calcium ions released into the acid solution were measured using icp-optical emission spectroscopy. The specimens were observed using scanning electron microscopy. Results Mean values (standard deviations) for the released calcium ions (milligrams per liter) from the control, CPP-ACP and Novamin groups were 23.65 (7.80), 29.76 (6.55), and 45.90 (9.61), respectively. The Novamin group had significantly higher mean value than the control group and the CPP-ACP group (p < 0.05). Mean values of the control and CPP-ACP groups were not significantly different (p > 0.05). Conclusion The amount of calcium ions dissolved in citric acid from the Novamin group was significantly higher than the control and the CPP-ACP groups. The results from SEM showed that these remineralizing agents provided resistance to citric acid erosion of pellicle-covered enamel.
