Effect of commercial pomegranate drink on the tooth enamel surface

Abstract Background: Low temperature atmospheric plasma has been studied in biomedical fields but the fluoride application effect of plasma on deciduous teeth has not been studied. This study examined the fluoride application effect of plasma devices (low frequency helium and microwave argon plasma) on the enamel surface of deciduous teeth.Methods: In the tooth specimens of the control group, only 1.23% acidulated phosphate fluoride (APF) gel was applied, whereas APF gel and plasma were applied to the specimens of the experiment group. The fluoride on the enamel surface was measured at different treatment times, and its retentivity was also observed over a 4 week period using an electron probe micro analyzer, which is a strong detector of fluoride. The study protocol was reviewed by the Institutional Review Board (IRB; PNUDH-2014-026) of Pusan National University Hospital.Results: More fluoride was measured and maintained in the experiment group than the control group, and the amount of coated fluoride increased with increasing applied frequency. A comparison of two types of plasma revealed the microwave argon plasma to have a higher application effect of fluoride than the low frequency helium plasma. This study suggests that fluoride application using plasma could be an effective and lasts longer than the method of applying only fluoride. Conclusion: The fluoride application with low temperature atmospheric plasma which is safe device is an innovative method to prevent dental caries and decrease number of visiting to dental clinic in children.

Background: Consumption of orange juice which had acidic quality will cause a demineralization on enamel. The most effective way to prevent the demineralization process was by involving remineralization agents. Fluoride was effective to improve remineralization but has toxicity effect and caused fluorosis at certain dose. Another alternative for remineralization agent without providing side effects is theobromine contained in cocoa peel extract (Theobroma cacao). Objective: To explain the effect of theobromine and NaF 2% exposure on enamel surface hardness after immersion in commercial orange juice. Method: Twenty-seven cattle incisors were cut into a square shape 1x1 cm and then planted in a round resin mold then divided into three groups. All three groups were immersed in orange juice beverage for 60 minutes. The control group was immersed in distilled water, group I was given theobromine 200 mg / L, and group II was given 2% NaF after exposure for 96 minutes. Surface hardness measurements were carried out using the Wolpert Micro Vickers Testers tool. Results: There was a significant difference (p <0.05) between surface hardness of tooth enamel from the control group and theobromine group and there was also a significant difference between the control group and the NaF group. However, there was no significant difference (p> 0.05) in the NaF group with theobromine group. Conclusion: The effect of exposure to theobromine and NaF 2% on surface enamel hardness after immersion in orange juice beverage has the same result.

Background: Tooth whitening usually includes the direct use of gels containing carbamide or hydrogen peroxide on the tooth enamel surface through a wide variety of products formulas. A generally new advancement in whitening of teeth uses the significant importance of the tooth color shift from yellow to blue in delivering a general enhancement in the observation of tooth whiteness. The aim of the current work was to measure the tooth whitening effects, surface roughness and enamel morphology of six different types of blue covarine-containing and blue covarine-free toothpastes using in vitro models. Methods: A total of 70 sound extracted human premolars were randomly and equally divided into seven groups, and each subjected to tooth brushing using different toothpastes. Tooth color and enamel surface roughness were measured before and after the brushing procedure using a white light interferometer, and scanning electron microscopy (SEM) was used to assess tooth surface after the procedure. Results: Toothpaste containing blue covarine resulted in the greatest improvement in tooth color amongst all groups as well as a statistically significant color difference when compared to blue covarine-free toothpaste. Furthermore, blue covarine-containing toothpaste resulted in fewer morphological changes to the enamel surface. This was confirmed with SEM images that showed smooth enamel surfaces with fine scratches. Conclusions: The results from the present study show that blue covarine containing toothpastes are reliable, effective in tooth whitening and produce less surface abrasion when compared to blue covarine-free toothpastes.

Demineralized Enamel

This paper investigates in situ remineralization of the acid-etched natural enamel surface, by incubation in a phosphate solution with neutral pH, at 37 �C for 4-10 days, without using any enamel matrix derivative (EMD). We investigated the morphology, crystallinity, chemical composition and structure of the newly grown layer onto the natural enamel surface stored in contact with artificial saliva (AS) having a composition similar to natural oral environment. The crystalline phases, crystallite size and orientation, as well as the chemical and phase composition of the remineralized dental enamel samples were studied by scanning electron microscopy coupled with energy dispersive X-ray spectrometry, Fourier transform infrared spectroscopy and X-ray diffraction. The experimental results showed that the enamel crystals grown on the demineralized enamel surface are mainly Ca-deficient apatite hexagonal structure. Fluoridated hydroxyapatite and sylvite-type KCl crystallites, which amount considerable increased in the case of sample stored in AS for 10 days, were also identified.

Abstract The aims of this study were evaluate cytotoxicity, genotoxicity, antimicrobial activity of desensitizing toothpastes compared to a common one and the surface roughness of tooth enamel submitted to brushing with these toothpastes. Samples of three desensitizing toothpastes (Colgate Sensitive, Sensodyne and Oral B Sensitive) and common toothpaste (Colgate) were placed in contact with gingival human fibroblasts. Cytotoxicity and genotoxocity were measured by MTT assay and micronucleus test. Antimicrobial activity of the toothpastes extracts against C. albicans, S. mutans and S. aureus were assessed. For surface roughness evaluation, bovine teeth were submitted to 10.000 brushing cycles. The results were analyzed statically using Mann-Whitney U, ANOVA and Z tests (p<0.05). All toothpastes caused cytotoxic effect to the cells (p<0.05), except Colgate Sensitive. The toothpastes did not increase the number of micronuclei compared to the untreated control group. Colgate eliminated all the evaluated microorganisms at lower concentrations compared to Colgate Sensitive and Oral B Sensitive, which were not able to eliminate S. aureus. Sensodyne did not reach the minimum microbicidal concentration. The surface roughness of tooth enamel increased after brushing with Colgate Sensitive and Oral B Sensitive, however the comparison between groups showed no difference on the enamel surface roughness presented by desensitizing toothpastes when compared with the common one (p>0.05). Based on these results, we can conclude that although none toothpaste has induced genotoxicity, Colgate Sensitive was also not cytotoxic. Colgate was the most effective against the microorganisms, and there were no differences on the enamel surface roughness between the groups.
