AbstractIntroductionThe efficiency of five natural antioxidants (curcumin, cranberry, pomegranate, grape seed extract (GSE), and açai berry) in reducing lipid oxidation in dog food was compared to that of the synthetic antioxidant butylated hydroxyanisole (BHA).Material and MethodsIn two different experiments content parameters were measured after 12 days of storage at 55°C. In experiment one, the natural antioxidants were added at 0.2% and BHA at 0.02% of the food (DM basis), and samples were analysed for thiobarbituric acid-reactive substances (TBARS). In experiment two, the effects of GSE and curcumin at two admixture proportions (0.1% and 0.2% of food DM) on omega-3 fatty acid (FA) content were evaluated.ResultsTBARS values were lower than the control (P < 0.01) for curcumin, cranberry, pomegranate, and GSE but not for the açai berry (P > 0.05). By day 12, although there were no significant differences (P > 0.05) between the two curcumin treatments, they preserved higher concentrations of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) (P < 0.05) than the BHA and control treatments. The addition of GSE or BHA to dog food held (P < 0.05) the concentrations of EPA higher than the control. The concentrations of EPA and DHA for the 0.2% GSE treatment were greater (P < 0.05) than the 0.1% GSE treatment. Grape seed extract at 0.2% lost less (P < 0.05) EPA concentration than BHA.ConclusionThe present results showed that, except for açai berry, the tested natural antioxidants could be used as a substitute for BHA in dog food.

Background and Aim: The bleached enamel surface requires application of antioxidant as there will be continuous release of free oxygen radicals. It would be beneficial if remineralizing agent which is recommended after bleaching also provides an antioxidant therapy. The natural antioxidants are colored. Hence, the aim of the present study was to evaluate the effect of natural antioxidants on the shade of the bleached enamel. Materials and Methods: Thirty single rooted maxillary anterior teeth were selected for the study. For all the samples middle third portion of the labial surface of the teeth was standardized using computerized cellophane stickers. Bleaching was carried out with 22% Carbamide peroxide gel (Philips Zoom Nite White). Based on the type of antioxidant solution application, samples were divided into three groups of ten samples each. Group I control (n=10) Group-II (n=10) 10% wheat grass solution (Sresta natural Bio products, India) Group-III (n=10) 5% grape seed extract (Zenith nutrition, Medizen Labs Pvt.Ltd, India). L, a, b values were recorded with spectrophotometry (Vita Zahnfabrik H. RauterGmbH & Co. KG,Bad Sackingen, Germany) thrice for each sample at the three respective time periods i.e at baseline, after bleaching and after antioxidant application. Results: ΔE values were subjected to statistical analysis using one way ANOVA with p>0.05 and the results were tabulated. It was observed that there was statistical insignificant difference between the groups with a p value of 0.295(p>0.05). Conclusion: The antioxidants 5% grape seed extract and 10% wheat grass extract did not affect the shade of the bleached enamel. Keywords: tooth bleaching, antioxidant, shade, spectrophotometry

The bond strength between resin-dentine is determined by the integrity of collagen, dentine and resin monomers. The susceptibility of the dentine bond results from the instability of the bonding structure that adheres to the bonding material. This can be achieved by using collagen cross-linker, synthetically and naturally in dentine substrates which are effective in protecting collagen fibrils from degradation, as proanthocyanidine. The aim of this study was to see the effect of grape seed extract as a crosslinker on the stability of dentine collagen and see the differences between groups. This study used 27 fresh premolars or third molars which were divided into 3 groups, namely group I giving grape seed extract 6.5%, group II giving chlorhexidine 2%, and group III only giving bonding ingredients. Samples were analyzed using SEM with 1000x magnification.  Data was analyzed using the kappa statistic, Kruskal-Wallis, dan Mann-Whitney. The result of the study significant differences between treatment groups (P <0.05), the 2% chlorhexidine group showed the highest value compared to the grape seed extract group and without treatment. Grape seed extract can be used as an alternative to chlorhexidine as a crosslinker to maintain bone strength of the composite restoration

Interest in the biological role of bioactive compounds present in medicinal herbs has increased over the last years. Of particular interest are plants that have an anti-Alzheimer activities. Several plants can be useful for Alzheimer (AD) management. Such as these which have anti-inflammatory activity, acetylcholinesterase (AChE) inhibitory action, antiapoptotic, slow the aggregation of amyloid peptide and antioxidant activities. Grape seed extract (GSE) is a complex mixture of several compounds, mostly represented by polyphenols and flavonoids. Their consumption is safe and is recognized to exert several health benefits. GS flavonoids have been associated with the reduced risk of chronic diseases, we present some findings on the potential benefits of GSE for the treatment of AD.

Abstract Aim: The aim of this study was to compare the reversal of shear bond strength of composite to bleached enamel immediately after bleaching followed by application of various antioxidant solutions. Material and Methods: Seventy central incisors were divided into seven groups. Groups I and II served as unbleached and bleached controls respectively. Groups III, IV, V, VI and VII served as the experimental groups and were subjected to 37.5% hydrogen peroxide bleaching followed by 10 min application of 10% sodium ascorbate, 25% alpha-tocopherol, 6.5% grape seed extract, 5% lycopene and 5% green tea extract respectively. Following composite bonding, shear bond strength was determined and the results were analyzed using ANOVA followed by Post Hoc Multiple Comparisons test. Results: The bond strength values for Group I (positive control) were maximum and significantly different than all the other groups except Grape seed extract group (Group V). When compared to Group II (bleached control), all the groups showed significantly higher bond strength. Significant difference in the bond strength values were seen between Group III (10% sodium ascorbate) and Group V. Also values for Group V were significantly different from Group VI (5% lycopene). All the other values showed insignificantly different results. Conclusion: All the antioxidant solutions improved the shear bond strength values after bleaching but only Grape seed extract application reversed the values to the non bleached levels. Lycopene was least effective. Other antioxidants showed comparable results.
