“…The results of our study show that, within the sensitivity of the applied method, the etching procedure significantly affected the dental enamel, in comparison with the bleaching method that used different concentrations of carbamide peroxide [12,13]. The results of this study are in agreement with previous literature reports [14,15].…”

“…These modifications are associated with the demineralization process which occurs by application of the etching agent on the enamel surface of teeth. By etching procedure the degree of demineralization is higher than that resulting from bleaching treatments of teeth, as our previously studies revealed [12,13]. Figure 4 presents the initial surface of one incisor in comparison with its surface after the etching treatment with ortho-phosphoric acid.…”

“…3suggesting a loosening of Ca-O bonds and a redistribution of the electron density to the adjacent P atoms and morphological changes on teeth surface. Therefore, the bleaching methods led to structural defects (erosion) of the enamel which become meaningful by increasing the concentration of the bleaching agent [12,13].…”

The acid etching procedure represents a procedure that increases the bond strength between the etched enamel and the composite resin. The aim of this study was to evaluate the effect of ortho-phosphoric acid 37% on the morphology and composition of the enamel surface. The surfaces of four extracted teeth (two incisors and two premolars) were etched with 37% ortho-phosphoric acid solution for 15 seconds. The teeth were examined by ATR-FTIR spectroscopy and SEM microscopy in order to determine the degree of the enamel demineralization. A major change on teeth composition and morphology has been found. The results are discussed and compared with those of the effects of different concentrations of bleaching agent (carbamide peroxide) on the enamel surface. Etching with 37% ortho-phosphoric acid caused structural and morphological changes to the dental enamel surfaces.

Analysis of the binding interactions of ibuprofen and silicified-microcrystalline cellulose (SMCC) has been undertaken. Co-processing of ibuprofen with SMCC was carried out by solid state ball milling, and aqueous state equilibration followed by freeze drying to investigate the effect of silicified-microcrystalline cellulose on ligand. Molecular docking study revealed that ibuprofen formed complex through hydrogen bond with microcrystalline cellulose (MCC) and silicon dioxide (SiO 2); the binding energy between MCC and SiO 2 , and ibuprofen and SMCC were found as-1.11 and-1.73 kcal/mol respectively. The hydrogen bond lengths were varying from 2.028 to 2.056 Å. Interaction of Si atom of SMCC molecule with Pi-Orbital of ibuprofen has shown the bond length of 4.263 Å. Significant improvement in dissolution of ibuprofen has been observed as a result of interaction. Binary and ternary interactions revealed more stabilizing interactions with ibuprofen and SMCC compared to SMCC formation.

“…However, for every two fluoride ions, tencalcium ions and six phosphate ions are required to form one unit cell of fluorapatite (Ca10(PO4)6F2). This means that, in case of topical application of fluoride, the availability of calcium and phosphate ions can be the limiting factor for net enamel remineralization to occur [1,6,7].…”

The aim of the present study was to assess the remineralizing potential of 10% casein phosphopeptide-amorphous calcium phosphate complex (CPP-ACP) -Recaldent used alone or with fluoride (CPP-ACFP) as compared to fluoride mouthrinse for the non-invasive treatment of occlusal non-cavitary caries lesions in vivo.A total of eighty subjects were randomly assigned to four groups, i.e. group 1 - 10% CPP-ACP, group 2- 10% CPP-ACP + 0.2% NaF, group 3- 0.05% NaF mouthrinse and group 4 �control. The lesions were assessed using visual examination and DIAGNOdent measurements. After 12 weeks of using the corresponding product, the results showed that the highest decrease in fluorescence was produced by CPP-ACFP (from 16.28�1.40 to 6.53�0.59, p=0.002), followed by CPP-ACP (from 15.70�1.82 to 8.18�0.70, p=0.004) and fluoride mouthrinse (from 14.32�1.72 to 7.88�0.68, p=0.005), significantly higher than in the control group (p[0.05). No significant differences were found between the three treatment groups.
