Grape seed is option for damage in dental restoration

Search from Ribeirao Preto Dental School (FORP) USP concluded that grape seed extract may be an alternative to combat damage in composite resin restorations, the material used in restorations. According to experts, the durability of restorations is currently considered one of the main problems facing the dental field.

Grape seed extract is a powder compound which can be used in diluted form.
Study carried out by the dentist Ana Beatriz Silva Sousa assessed the grape seed extract and two other solutions inhibitors of enzymes present in the mouth and that cause damage to the restorations. The researcher said that the results showed that the grape seed extract is more effective than chlorhexidine and as effective as doxycycline, materials normally used, with the advantage of being a natural product. "As doxycycline, the inhibitor solution use of grape seed extract prolongs the life of restoring resin and thus helps reduce extra expenses replacement aesthetic treatments.

Ana Beatriz explains that grape seed extract is a powder compound which can be used in diluted form; there are ongoing studies for the purpose of encapsulating the solution. Ana Beatriz´ part research was done at the University of Illinois at Chicago, USA. "Currently, the group where I worked in Chicago is researching ways to incorporate the grape seed extract in phosphoric acid we use in our traditional restorative protocol," he says.

To perform the test, with grape seed extract, they used 48 human teeth without cavities and without restoration. In each of them an opening was made in the center, and separated into four groups, one control group that did not receive the application of any solution, and the other three groups which have been implemented before the restoration, chlorhexidine, doxycycline and the solution with grape seed extract.

Then the traditionally restoration was carried out, the same as is done in the dental office. After, the samples were tested with artificial saliva and mechanical cycling (process that simulates the wear of a tooth for a certain period) to evaluate the bond strength between the dentin and the restorative material.

The results showed that the use of inhibitory substances did not alter the bond strength between the teeth and the shutter, but otherwise all solutions, including with grape seed extract, were able to reduce the damage caused by MMPs calls ( metalloproteinases), enzymes that act directly in the mouth and teeth causing damage to the restorations.

According to the researcher, in order to get better results in the durability of dental restorations, the main objective of the study was to evaluate the effectiveness of inhibitory substances. "The results add to other similar developed in Brazil and abroad, and shows grape seed extract as an alternative natural compound to act in the reduction of dental restorations of the damage."

The next steps of the research, he says, is to advance the application of the tests. "We will continue the evaluation of the effect of the use of inhibitors of MMPs and other enzymes that degrade the dentin adhesive restorations, but subject to more severe aging conditions." The thesis Effect of using bioactive primers on dentin-adhesive interface, was guided by Professor Fernanda de Carvalho Panzeri Pires de Souza FORP. The defense was in last July.
