Effect of Remin Pro and Neutral Sodium Fluoride on Enamel Microhardness After Exposure to Acidic Drink

Abstract

Background and Aim: High consumption of carbonated diet soda is the most common etiologic factor for dental erosion. The purpose of this study was to evaluate the microhardness of the enamel surface eroded by cola after treatment with Remin Pro and neutral sodium fluoride. Materials and Methods: This in vitro experimental study was performed on 20 extracted premolars with no corrosion, abrasion, crack or hypocalcification. To properly evaluate the microhardness, the buccal surface of samples was polished with sandpaper and then the teeth were immersed in acidic drinks to achieve demineralization. Next, the microhardness was measured at three new points and the samples were randomly divided into two groups for application of neutral sodium fluoride and Ramin Pro. Duration of treatment was in accord with the manufacturer's instructions and the microhardness of the samples was measured again. Results: Significant differences were found between the two groups after the treatment, and the fluoride group showed higher microhardness (P=0.04). Also, the microhardness value was significantly different at the three time points (P<0.001). Conclusion: Cola decreased the enamel microhardness while Remin Pro and neutral sodium fluoride increased the microhardness of enamel. Neutral sodium fluoride showed better remineralizing effect on enamel microhardness.

The Preventive Effect of Remin Pro and Neutral Sodium Fluoride on Erosion of Dental Enamel: An In Vitro Study

“…This was in line with previous reports on this material [5,6]. It should also be noted that, as mentioned earlier, xylitol, hydroxyapatite, and fluoride can be effective in the decrease of surface roughness by inducing supersaturation of calcium and phosphate ions to promote remineralization, filling porous area, forming a protective film on the tooth surface, and inhibiting the adhesion of bacterial plaque [22]. Hydroxyapatite fills superficial enamel lesions and irregularities that arise from surface demineralization.…”

“…Some studies have shown that Remin Pro can be absorbed by saliva pellicle, creating an enriched reservoir of calcium that is able to increase remineralization. Furthermore, Remin Pro can increase microhardness [5,6,22]. In the current study, surface roughness after exposure to acid was increased in the two groups, but in Remin Pro groups, this enhancement of surface roughness was less than the initial surface roughness.…”

“…The amount of erosion was evaluated using profilometry with a contact probe. This is a common method for erosion evaluation, which has been used in different studies, and the accuracy of this device has been proven [6,[21][22][23]. The samples were polished well so the surface roughness of the samples was in the range of the measuring device (0.025 to 12.5 µm) with ≤±10% accuracy.…”

“…Hydroxyapatite fills superficial enamel lesions and irregularities that arise from surface demineralization. Furthermore, fluoride is converted to fluorapatite on the tooth surface, which makes the tooth more resistant to acid attacks [22]. In addition, fluoride ions are deposited in dentinal tubules and seal them.…”

Comparative Assessment of Enamel Microhardness Using Various Remineralising Agents on Artificially Demineralized Human Enamel

“…A remineralization treatment regimen (Remin Pro and Clinpro) was applied two times a day for three minutes as per the manufacturer's recommendations to make it clinically relevant [19,20]. The efficiency was evaluated at 14 days as it takes a minimum of 14 days for any toothpaste/cream to express its desired therapeutic effect [21].…”
